[Q: WHAT IS THIS ROAD RUNNER UNOFFICIAL FREQUENTLY ASKED QUESTIONS POSTING?]
This is a volunteer effort of a loosely compiled list of Frequently Asked Questions and issues that have been posted and answered in the roadrunner.help, roadrunner.faq, roadrunner.d newsgroups, e-mail and in discussion with the San Diego Southwestern Cable TV Road Runner support. These answers represent the combined efforts of various individuals. These answers are not necessarily endorsed by Southwestern Cable TV or Times Warner, Inc.
** Update ** This faq is was initially created in 1997. Much of the information
within is outdated. Keeping that in mind, feel free to use what you may deem
appropriate. However, I would recommend that you go to RoadRunners technical
support web site at http://help.rr.com.
[Q: WHAT IS ITS PURPOSE?]
The main purpose of the Road Runner Unofficial Frequently Asked Questions
posting is to assist people with their use of the Road Runner system. The
information provided here is to be considered only as a possible way to
solve a problem or provide assistance while using the Road Runner environment.
Because many issues have a tendency to come and go rather quickly in newsgroups,
this will also help to archive issues for future reference, particularly
for new users.

[Q: WHERE CAN I FIND THE LATEST VERSION OF THIS FAQ POSTING?]
Currently this FAQ is available at the page you are viewing:
* Web site: http://home.san.rr.com/main/rrfaq/index.html
[Q: HOW OFTEN IS THE ROAD RUNNER FAQ UPDATED?]
It is my intention update the FAQ based on a few factors:
How much new information there is to communicate.
The type and amount of response I receive from users.
How long the posting is retained and is available
to newbies.
How much time I have available to volunteer to the
project.
[Q: HOW CAN I HELP WITH THIS POSTING?]
This FAQ only works with your input. Please feel free to give me your,
questions, suggestions on new topics, opinion regarding the format, and
content, additional resources or any information that you would like to
gripe about. Do not reply to this post in the newsgroup. It will
create too many duplicated posts and make it difficult to manage and use.
To get in touch with me see contacts below. Constructed criticisms are
always welcomed.
[Q: FORMAT?]
Notice, I grouped the issues into categories hopefully to make it easier
to use. In the future these will be hyperlinked.

PROXY SERVER
================
date: 07/24/97
[Q: DO I HAVE TO USE THE PROXY SERVER?]
No. As of 07/22/97 port 80 has been opened up. This means that using
the proxy server is optional.
[Q: HOW DO I SET THE PROXY SERVER FOR NETSCAPE?]
Some applications will require setting the proxy server using only the
URL name and not the HTTP://
For example:
HOST: proxy-server
PORT: 8080
Other applications may require the HTTP://
For example:
HOST: http://proxy-server
PORT: 8080
[Q: WHAT NEEDS TO BE PUT INTO THE NO PROXY SERVER?]
It is important to separate the arguments correctly per the applications
requirements. Some use ";" or "," or " ". You
may have to play around a little to find the correct method. See next
question.
[Q: HOW DO I ACCESS ANOTHER SAN DIEGO ROAD RUNNER USER'S SERVER?]
NETSCAPE COMMUNICATOR 4.0 PR 3
For do not use proxy:
* Specify san.rr.com and anybody accessing the any
RR site using the URL within the intranet should be able to get there.
* And/Or specify the full IP Address 204.210.10.123
and anybody using the IP Address within the intranet should also
be able to get there.
Notice Netscape for this version is using "," to separate arguments.
Other releases used ";" or " ".
ams-server,login-server:8081,ftp://,gopher://,san.rr.com,204.210.10.123
IE 3.01B
For do not use proxy:
use dt*.san.rr.com
and/or 204.210.*.*
Make sure that the argument is not broken between lines.
ams-server;login-server:8081;ftp://;gopher://;
204.210.*.*;dt*.san.rr.com
LYNX
1) Edit your lynx.cfg and modify/add the following line:
http_proxy:http://proxy-server.san.rr.com:8080
2) Contributed by Guy Berliner
To use a proxy server with
lynx, set an environment variable called PROTO_proxy, where PROTO is the
protocol
for which the proxy
is used. For example, to set up an http proxy using the server proxye3-atm.san.rr.com,
port 8080
in a Bourne style shell,
add export http_proxy=proxye3-atm.san.rr.com:8080
[Q: WHERE CAN I LEARN MORE ABOUT THE PROXY SERVER?]
Proxy software details are available at www.netcache.com. Details on
the latest release are at
http://www.netapp.com/products/netcache/

NEWSGROUPS
==============
date: 06/30/97
[Q:WHAT IS THE PURPOSE OF EACH ROAD RUNNER NEWSGROUP?]
Each group has a specific function:
roadrunner.d
Topic discussion.
roadrunner.faq
Many previously asked questions
and answers can be found here.
roadrunner.flame
Allows for impassioned comments
(wining, gripes, etc.).
roadrunner.help
Place for questions and
answers related to using the roadrunner environment.

[Q: WHY AM I NOT ABLE TO READ ALL THE NEWSGROUPS THAT I AM ABLE TO GET VIA ANOTHER NON ROAD RUNNER ISP?]
Many people have an issue with this and RR support says that the full
number of groups will soon be available.
[Q: HOW MANY NEWSGROUPS DO WE RECEIVE?]
date: 08/01/97
It is 29424.
[Q: HOW LONG DOES ROAD RUNNER RETAIN THE NEWSGROUP POSTINGS?]
date: 04/13/97
I repeat, our retention period for ALL groups (including binaries)
is 7 days (EXCEPT road runner groups which are kept for 10). Our
feed is acceptable at this time. Of 202,393 articles available yesterday,
we accepted 186,568. This is 92% -- we are normally within the 90%
to 98% range. The loss is due to groups we do not carry. The
speed of article retrieval from our upstream news server will increase
when we triple our external bandwidth on Wednesday. You are, of course,
free to continue paying for additional news services elsewhere.

For a list of usenet servers:
http://search.yahoo.com/search?p=usenet+servers
For a comparison on different commercial vendors
http://www.airnews.net/compare/study.html
[Q: WHAT KIND ON EXPERIENCES HAVE PEOPLE HAD WITH OTHER USENETS?]
I just subscribed to AirNews myself ($9.95 a month) - personally, I think the usenet articles available on RR are severely lacking.
I've used alt.net for over a year now and besides having ALL the groups
including clarinet and biznet (?), there seems to be a much longer expire
time than RR. The binary groups usually expire no less than 5 days and
the non-binaries stay a few weeks before expiring.
Jim
FWIW, here's my take on some of the commercial news servers -
- I subscribed to zippo news for a month, and they definitely
had a better coverage than RR. However, the connection is
pretty slow, and no Clari newsgroups.
- Alt.net allows you to connect to their server and view some
of the
news.xxx groups. However, again, the connection
seemed pretty slow. I can't say anything about their coverage
- I subscribed to airnews (http://www.airnews.net/),
and they definitely had a better selection than RR, and its a fairly fast
connection. They also have clari newsgroups

LOGIN
=======
date: 08/01/97
[Q: I WANT TO LOGIN BUT WANT TO USE A DIFFERENT BROWSER OR NONE AT ALL.]
Go to the RR Login Software dialog box Browser/Change/Change Point to the program (IE, Netscape) or batch file (ie. Null Batch, Atom Time Batch) that you want to start up.
NULL BATCH
You can run a NULL batch file that won't run any browser at login.
Then you can run, or not, the browser when you are ready. See:
http://home.san.rr.com/main/rrfaq/null1.exe
ATOM TIME BATCH
Will automatically adjust the systems Date & Time with the current
Atomic Clock Time value and won't run any browser at login. Then you can
run, or not, the browser or application when you desire. See:
http://home.san.rr.com/main/rrfaq/atomtim1.exe
[Q: IS THERE A BETTER LOGIN PROGRAM?]
WINBATCH
Replaces this login program. Trial software can be downloaded from:
http://www.windowware.com/winware/download.html#download
Milo D. Cooper at mcooper1@san.rr.com offers the following script
It's basically a Windows95 management language. For anyone using WinBatch
to automate his/her Road Runner login, I've modified my autologin script,
in case you're interested. My main interest was getting rid of the
crude time delays, in favor of prompting from the actual RR login software.
Here's my new login script:
If WinExist("Road Runner Login Software") == @TRUE Then Exit
Run("C:\RUNNER\LOGIN.EXE","")
IntControl(36,"Road Runner Login Software",-1,0,0)
IntControl(35,25,0,0,0)
SendKeysTo("Road Runner Login Software~","password{ENTER}")
While MsgTextGet("Road Runner Login Software") != "Connection to
Road Runner System is established."
EndWhile
SendKeysTo("Road Runner Login Software~","{ENTER}")
WinHide("Road Runner Login Software")
Notes:
'While...established."' is all one line (in case
your news reader wraps it around).
IntControl 36 waits for an input request from the
RR login window, then it lets the script proceed to enter the password.
This is (obviously) quicker than any Delay or TimeDelay
command, and more reliable as well.
IntControl 35 merely sets the keystroke input speed
to 25 milliseconds, in case the rate has been changed elsewhere.
I also made a slight modification to my autologout batch:
If WinExist("Road Runner Login Software") == @FALSE Then Exit
WinShow("Road Runner Login Software")
PlayWaveForm("sound.wav",1|16)
Display(2,"Road Runner Login Software","That's All, Folks!")
WinClose("Road Runner Login Software")
... Just so I get user-friendly, audiovisual con-formation that I've logged out.

[Q: IF I LEAVE WINDOWS ON FOR A DAY OR SO, I BECOME UNABLE TO CONNECT TO ROAD RUNNER PROPERLY AND I HAVE TO REBOOT TO BE ABLE TO CONNECT.]
There are two possible explanations, because Road Runner requires that you run two programs on an ongoing basis to remain logged in.
The first is the DHCP client, which must renew the IP address lease at least once per hour. The DHCP client is a standard part of W95. The second is the RR login program, which sends an unacknowledged keepalive every minute. If this doesn't happen, you're silently logged out. It's also possible that your entire system (or at least its network stack) is crashing for some other reason.
To help isolate the problem, see if you can ping successfully after
the problem occurs (sendings pings does not require that you be logged
in). If this works, the problem is almost certainly with the login program.
If it does not, try running WINIPCFG.EXE and clicking on the "renew all"
button to renew the DHCP lease. If that works, the problem is with your
DHCP client. If that doesn't work, then the problem must be elsewhere.
Phil Karn
[Q: WHY DO I GET A MESSAGE DURING LOGIN THAT SAYS TO "TRY AGAIN LATER".]
The current heartbeat (or as you call it, 'ping-pong') is actually five
minutes. You need to ALWAYS logout before closing the login, shutting
down the machine, etc. This will stop the please try later problem.
The BEST technical fix is to completely get rid of the login. This is something
we hope to do soon.
David Somers
[Q: I NOTICED A NEW LOGIN FILE WAS DOWNLOADED AUTOMATICALLY?]
If you have the download version updates box checked, then it's downloading
a new "Toshiba" client with a five minute heartbeat and also 3.02 of IE.
If you are using rrlogin or rrconnect, then it won't make a difference,
otherwise, the client works better. Of course, the
best solution is to dump the client entirely, which we're working on.
Dave Somers
This requires that you login using your master account. You will be
prompted to run the install.exe file.
======================
STATIC IP ADDRESSES
======================
date: 07/18/97
[Q: IS THERE ANYWAY WITH ROAD RUNNER TO GET STATIC IP ADDRESSES AND POSSIBLY NAME SERVICES?]
At this time Road Runner does not provide static IP Addresses. Here is a site
that (will) offer domain names to dynamic IP Address sites.

CACHE
========
date 08/01/97
[Q: HOW DOES THE CACHE WORK?]
For a COMPLETE and DETAILED description of EXACTLY how the cache works,
I direct you to the following url:
http://catarina.usc.edu/danzig/
date: Saturday, April 26, 1997
Dave
<snip>
So Dave, forget what the above message said, but I'm asking this:
am I seeing the benefit of harvest cache only, or am I assuming correctly
that is will be indicative of the router upgrade improvement, as you migrate
each router to the new software, or what would you suppose?
Mike
Mike,
What you are seeing is a combination of things. Your request
is going to your local distribution hub (one of 15 distributed
throughout the service area -- in your case #11). It is traversing
cable router 11 and then TAS 11 (an UltraSPARC 170) then down the wire
to the harvest cache first. The cache is running on 4 Ultra Enterprise-2
170s (dual processor) with substantial raid storage. If the page
is in the cache and not scheduled to expire then it is loaded from the
cache and sent back to you. If it is not (which would be unusual
but not impossible for the local content server), then it is retrieved.
In this case from the local server but in most cases from the Internet.
None of the production routers has been upgraded yet so this is not what
you
are seeing. A lot of news postings have attempted to place the
blame for slowness on the cache. This is EXTREMELY unlikely.
I can't conceive of a scenario in which the cache would slow things down
though I am willing to investigate anything reported. In most cases
this is, as you've suggested, caused by external sites, routers, etc. which
are out of our control
The problem with NetMedic is that it uses ICMP for it's determinations
of what is happening. The cable routers don't handle ICMP well and
will usually give you strange results. Also, various packet filters,
customized load-balanced DNS and other security measures will sometimes
make netmedic think that DNS is broken (when it's not) and "suggest" a
fix. DON'T LET IT FIX ANYTHING! It will generally insert some
parameters into your TCP/IP configuration that will make it impossible
to logon or connect.
Dave Somers
[Q: HOW SHOULD I SET MY MEMORY AND DISK CACHE IN MY BROWSER?]
You will have much better results reducing your memory cache to about
1 meg and your disk cache to about the same. This will greatly speed
up your retrieval of web pages. Let us do the "proxy server harvest" cache
for you :)>
Dave Somers
However, if you have a direct connect to the internet and are not using
the proxy server then you want to increase the memory and disk cache to
a level depending on the amount of ram and free disk space you have available.
I use 4k or 8k on my Win 95 machine.
[Q: WHY DO SOME GIF'S (MOSTLY INTERLACED GIF'S) NOT LOAD PROPERLY?]
Hitting "Reload" does not help in this case since the GIF image was
embedded in the page and "Reload" only reload the fresh page not the fresh
images. There are many reason for the cache GIF image to be damaged, lack
of disk spaces is the most common, IO error during transferring etc. Fix
by clearing your cache directory completely.

[Q: WITH A PROXY SERVER, ITS PRETTY OBVIOUS THAT PI'S ARE DYNAMICALLY DEFINED. DOES ANYONE KNOW HOW YOU CAN AT LEAST SEE THE IP YOU HAVE FOR YOUR SESSION?]
* Windows 95 use winipcfg
Windows NT use ipconfig
* Just go to a DOSshell (if you're using windows or windows95) and
type
arp -a
* Hit a site that shows your IP Address to you. Try

[Q: I WOULD LIKE TO KNOW HOW TO WORK MIRC AND PIRCH WITH THIS NEW SERVICE. CAN IT BE 32-BIT OR DOES IT HAVE TO BE 16-BIT?]
I've been using mIRC 32-bit right along. Proxy or no proxy, no
change to my mIRC setup. IRC is not using 80 or 8080 and works just fine.
I have been running an IRC Server for a month.

MULTIPLE COMPUTERS
=======================
date: 06/30/97
[Q: IS THERE A CHARGE TO CONNECT MORE THAN ONE COMPUTER TO THE ROAD
RUNNER CABLE MODEM?]
date: 04/22/97
For the next six months, your second computer will
be at no charge. Beginning November 1st, 1997, the charge will be
an additional $5.00. Best regards,

General Manager, Road Runner
[Q: I AM USING A ETHER H5 ETHERNET HUB TO CONNECT A DESK TOP AND A PORTABLE COMPUTER TO THE RR MODEM. DESKTOP WORKS FINE BUT CAN'T LOG IN WITH THE PORTABLE. WHATS WRONG?]
You need the equivalent of a "null modem" cable or adapter between the hub and the cable modem!! Called an "uplink adapter" or a "cross-over" cable, it's nothing more than a cross-wired section of UTP cable, with a male RJ45 on one end and a female on the other.
You use "straight-thru" cables from the NIC in each computer to the hub. But the "uplink" adapter section is required between the hub and the cable modem, which in this case, serves as a router for your LAN.
You can make this crossover/uplink adapter yourself, if you have the
crimp tool, and male/female plugs. Otherwise, it's best to just buy one.
[Q: CAN ANYONE GIVE ME A PARTS LIST AND SOME DIRECTIONS ON HOW TO GO ABOUT IT?]
You need to get an Ethernet Workgroup Hub, from various vendors.
Mine is made by Linksys, and has 5 ports, ran about $75 at CompUSA.
Hubs typically cost $60 and up. My 5 ports will be utilized as follows:
2
for 2 computers, 1 for an HP laser, and one the uplink to RR.
Try to get a hub with an "uplink" port (allows you to connect the hub to
other hubs), so that you buy the simplest, straight through cables.
Also, pick up a second (or 3rd, 4th) Ethernet patch cable (straight thru
if you have the uplink port on the hub), which is anywhere from $7-15 depending
on the length you get. You'll need one extra cable to link in the
hub, and one extra cable for each additional computer.
The installation can typically be done without changing any software.
Shutdown your system(s) completely, but leave the cable modem on. Power
up the hub as per the manufacturer's instructions. Take the end of
the Ethernet cable coming from the back of your system, and plug it into
a NON-uplink port of the hub. Do the same for all other computers.
Take an additional cable, lug one end into the back of the cable modem,
and the other into the uplink port of the hub. Restart all the systems,
and your one! I don't know of a small home office/workgroup hub that
requires software modifications to your system - it should be transparent.

[Q: HOW DO I CONNECT FROM WORK TO MY HOME ROAD RUNNER COMPUTER?]
Windows95:
Host machine (at home)
1) Share a directory (or more than one) using Explorer.
Assign a password to the share(s)!
example: Share name: CDRIVE
Path: C:\ Password: ABC
2) Run WINIPCFG to get the IP address of the machine at home
example: Adapter Address: 204.210.43.0
Client machine (at work)
1) Create or modify C:\<win95root>\LMHOSTS
(where <win95root> is the directory where Windows95
was installed)
Add a line with your PC's IP address and name.
An example of this file can be found in
C:\<win95root>\LMHOSTS.SAM.
example:
# comment C:\WIN95\LMHOSTS
204.210.43.0
HOMEPC
2) You should be able to ping your host machine now. example:
PING HOMEPC
3) Click on Start/Run... and enter the name of your home PC, preceded
by \\ example:
\\HOMEPC
4) In a short while an Explorer-like screen should automatically come
up and you can either work from here, or map a drive
letter by right clicking on a directory and selecting
Map Network Drive. Each shared directory will show up here. When
you click on a directory, Windows will ask you for
the password for that directory, assuming that you set one in "Host,
step 1".

[Q: I CAN NOT CONNECT MY DELL LAPTOP COMPUTER TO RR, I'M TRYING TO LOAD THE DRIVERS FOR MY 3COM PCMCIA CARD, IT ASKS FOR A FILE "ELPC3R.SYS"].
Check out the 3COM site:
"NDIS 3 for Win95 (mini-port) 3C562X.EXE

[Q: DOES RR SUPPLY THE ETHERNET CARD FOR MACINTOSH?]
Macintosh does not support the 3Com 3C508 or 3C509 cards that SWC has been
giving out. You should just go to a computer stores and buy a card. Try
using a NE-2000 clone.
==========
CERFNET
==========
date: 08/01/97
[Q: WHAT IS THE CERFNET?]
California Education and Research Federation Network. It was one of the original National Science Foundation (NSF)- sponsored "regional" networks, each hubbed at a NSF supercomputer center (in CERFnet's case, the San Diego Supercomputer Center on the UCSD campus). CERFnet connected sites in the Southern California area to the ARPANET, which was the Internet "backbone" in those days (56kb/s links!) Because of its status as the first San Diego area ISP, many long-time Internet sites (companies and universities) are connected to CERFnet, including Qualcomm, UCSD, Scripps, SDSC, SAIC, etc. This means a lot of traffic from Road Runner users goes to CERFnet.
As of 08/01/97 Road Runner's connection to the Internet is through MCI,
and CERFnet.

CABLE MODEM
===============
date: 06/20/97
[Q: INTERESTED IN RESEARCHING AND KEEPING UP TO SPEED ON THE CABLE MODEM SCENE:]
http://www.cablemodem.com
http://www.ansi.org
http://www.infinisource.com/
[Q: CAN I IMPROVE THE CABLE MODEM SPEED?]
First: This is not for everyone. Remember to backup the registry (System.dat,&
User.dat). You can use Regedit to do this.
Second: A problem exists in the 32 bit TCP\IP stack that comes with
Windows 95 where it does not acknowledge a packet transfer fast enough
and so the sending machine re-sends the same packet. Effectively you end
up receiving twice as much data as you should - which in turn means you
are only downloading at half speed.
You need to make sure that the "MaxMTU" parameter in your registry is set to a value appropriate for the cable modem. This probably is 1500. This apparently is the default.
You can use regedit to check it and change it. But rather than taking a chance and change the registry you can use a shareware program, "TCPIPCFG.EXE", that will do it for you and allow you to experiment with the value. If it is not already set, try setting it to 1500. If later you find that when you are using a regular dial up modem (14.4 - 33.6) and this causes a problem you might want to set it to 576 or what ever is best depending on the datagram you are receiving.
You can get "TCPIPCFG.EXE" at http://www.c2000.com/software/software.htm
If you want to learn more regarding this program you can go to the authors
page at
http://www.aimnet.com/~jnavas/modem/faq_a.htm#SolarisBug
[Q: I DOWNLOADED TCPIPCFG, EXTRACTED IT INTO WINDOWS/SYSTEM AND I DON'T KNOW WHAT TO DO FROM HERE. HOW CAN I TELL IF I AM RUNNING ONE OF THE UNSUPPORTED BUILDS THAT WERE MENTIONED? I ALSO DON'T SEE ANY MAXMTU IN MY REGISTRY.]
In the control panel / system you can get the reference to the Win 95 version build.
You should see a DUN TCP/IP in your control panel. I don't remember
if you have to restart windows but might give it a try. If you see
it and run it. It will probably say what your MaxMTU setting is, make sure
it is 1500.
[Q: IS THERE AN EASIER WAY TO TWEAK THE TCP/IP WINSOCK PARAMETERS?]

[Q: HOW DO I GET POINTCAST NETWORK TO RUN UNDER ROAD RUNNER? IT WORKED FINE WITH MY OLD ISP DIAL-UP?]
A Try starting RR login first.
B Try downloading and installing the most current version again. The
Pointcast Network is located at
http://www.pointcast.com.
C Make sure your PCN setting are correct.

=====
DNS
=====
[Q: IF YOU ARE EXPERIENCING ANY OF THE FOLLOWING, YOUR DNS SERVER IS PROBABLY IN NEED OF RE-CONFIGURATION BY RR.]
Here's the symptoms:
1. Can ping san.rr.com, but not external sites such as microsoft.com
from the DOS prompt.
2. Can tracert at DOS prompt san.rr.com, but not external sites. System
locks up.
3. Can't retrieve external e-mail from other ISP's via RR over TCP/IP.
4. Can't use RR without the proxy server settings enabled.
5. Can't have DNS Configuration enabled under the network settings.
6. Can't FTP sites using the URL name but can using the IP address.
[Q: HOW DO I OBTAIN MY DNS SERVER ADDRESS?]
WINDOWS 95:
A. Click on START, Click RUN, type "winipcfg", click OK
B. Click on "more info" and read the second line from the top
(DNS Server)
[Q: IN WIN95, HOW DO I SET UP A DNS DOMAIN NAME SEARCH ORDER SO THAT
I
DON'T HAVE TO PUT THE DOMAIN NAME ON ALL REFERENCES TO MACHINES
ON MY
NETWORK AT WORK?]
The question here refers to enabling you to do: "ftp mymachine" instead
of: "ftp mymachine.mydomain.com" (or telnet,
or ping, etc.,) since most likely you are used to doing the first thing
when you are at work, not the second.
Control Panel --> Network --> TCP/IP(for your Network adapter)properties --> DNS Configuration:
Enable DNS: checked
Host: "DEFAULT"
Domain: "san.rr.com"
(I'm pretty sure the Host and Domain get overridden by DHCP but something
needs to be there for Win95 to accept the changes to the DNS config)
DNS Server Search Order: <DNS server's IP address from winipcfg>
Domain Suffix Search Order:
san.rr.com
mydomain.com
com
edu
That should allow you to specify just the hostname in any machines at
san.rr.com and mydomain.com (and any other domains you put in the list
as well) and the names will get fully resolved. It should also let
you do things like "ftp theirmachine.netscape" or "telnet their machine.ucsd"
thereby removing the need to put .com or .edu at the end, respectively.
This is only there for the truly lazy like me :-) I find this very
convenient.

PING
=====
[Q: HOW DO I PING AN EXTERNAL SITE?]
WINDOWS 95
To "ping" external sites such as Microsoft do the following:
Windows 95:
A. Click on START, Click Run, type "command", click OK
B. Type cd\ and hit return
C. Type "ping san.rr.com" and hit return
D. This will produce the normal ping response
E. Now type "ping microsoft.com" and see what happens
F. If you get a blinking horizontal cursor, close the dos
window.
==================================
MICROSOFT INTERNET EXPLORER
==================================
[Q: HOW DO I UPGRADE MY INTERNET EXPLORER?]
date: 06/04/97
The upgrade to the most current version that Road Runner provides is
automatically performed when you login using your master account. Microsoft's
IE has been upgraded to ver 3.02. Make sure you have at least 18000KB
of free space available on drive "C". Make a note of your proxy settings,
especially the exceptions, (view -> options -> connection -> proxy server
settings -> exceptions) since the upgrade will overwrite them. For Windows
95 the file rrie95.exe (7536KB) is downloaded to C:\Runner\rr1e95. After
the upgrade you can delete the file if you desire.
[Q: MY NEW RR IE IS CRASHING REGULARLY. THE DETAILS OF THE ERROR MESSAGE ARE IEXPLORER CAUSED AN INVALID PAGE FAULT IN MODULE MSHTML.DLL AT 0137:635b906a?]
I suspect that your History folder or index that tracks the history
folder is damaged. Check this page for a possible solution
http://www.microsoft.com/kb/articles/q160/2/56.htm
Or
You may find the quickest way is to reinstall the IE program from the
floppy disks or perhaps RR has a copy of their IE on their site.
============
WEB PAGES
============
date: 08/01/97
[Q: WHAT ARE PERSONAL WEB PAGES?]
Personal web pages are simply a web site that the ISP provides its customers so they can publish their own pages and make them available to the Internet at large.
As of 08/01/97, San Diego Road Runner users have the capability to create
personal web pages on a Road Runner sponsored server.
=============
FRONT PAGE
=============
[Q: WHY SINCE INSTALLING RR, MICROSOFT PERSONAL WEB SERVER NO LONGER RECOGNIZES LOCALHOST, WHICH IS CRITICAL FOR WORKING WITH FRONTPAGE?]
Localhost should resolve to 127.0.0.1. Open up your hosts file and add: 127.0.0.1 localhost
Depending on your OS:
Unix
/etc/hosts (and
check /etc/resolv.conf or
/etc/nisswitch.conf)
Windows NT
%WindowsDir%\SYSTEM\DRIVERS\ETC
Windows95
%WindowsDir%
where %WindowsDir%
is where you installed Windows, e.g.
"C:\WINNT" or "C:\WINDOWS"

This is most likely a cable plant problem. In order to troubleshoot
this please email sysadmin@san.rr.com with your modem serial number, phone
number, address and as specific a description of the problem as possible
(ping tracing to tas.san.rr.com, mail.san.rr.com, what SPECIFICALLY
you are doing when you have a slowdown .. i.e., if you are accessing a
site outside of RR, then a traceroute to that site would help). I
apologize for the problems you're having but if you get us the info. we'll
do our best to fix it.
Dave Somers
[Q: WHY CAN I NOT CONNECT TO MSN?]
date: 08/01/97
The proxy server prevents RR users from connecting to MSN. There is currently no solution, so MSN accounts are, for the most part, useless here.
Unless you also have a Linux system on your network with the tunnel driver installed. You can then tunnel your packets to MSN via tunnel.qualcomm.com. These appear as IP-in-IP packets to the RR filter; the fact that they're really TCP packets to port 80 is hidden, so the filter will let them pass.
You may want to consider disabling your proxy-server by using direct
connection to the internet.
========================
DATA COMMUNICATION
========================
[Q: WHAT IS DATA COMMUNICATION SPEED?]
The speed of your internet connection is determined by the bits per second that data is transferred. This may vary from 9600 bps per second) to 2.488 Gbps (gigabits per second). In telecommunications a byte is probably best counted as 10 bits, to consider the start and stop bit that has to be added to each normal byte of 8-bits. 60,000 bytes per sec could equal 600,000 bits per sec.
The following information outlines the method of connection and the rate per second for each method:
Method = Rate Per Second
Frame Relay = 56Kbps
ISDN BRI = 64 Kbps
ISDN PRI = 23 * 64 Kbps (fractional T-1)
Dual Channel ISDN = 128 Kbps
E-1 = European T1. = 2.048 Mbps
E-3 = European T3 = Approximately 34 Mbps.
T-1 = 1.544 Mbps.
T-2 = 6.312 Mbps.
T-3 = 44.736 Mbps.
T-4 = 274.167 Mbps.
FDDI = 100 Mbps (fiber)
CDDI = 100 Mbps (copper)
OC3 = 155 Mbps
OC12 = 622 Mbps service.
OC48 = 2.488 Gbps service
10BaseT (Ethernet) = 10 Mbps
100BaseT (High Speed Ether) = 100 Mbps
DS-1 = T1: 1.544 Mbps. In Europe, same as E1: 2.108 Mbps.
DS-3 = Same as T3: approx. 44.736 Mbps

GLOSSARY
===========
10Base2
A form of Ethernet and IEEE 802.3 network cabling
using thin coaxial. It refers to I0Mbit/s speed Baseband transmission
ver 200 meters maximum length in practice 185m)
and is commonly known as Cheapernet.
10Base5
A form of Ethernet and IEEE 802.3 network cabling
using thick coax. It refers to 10Mbit/s speed Baseband transmission
and 500m maximum length.
10BaseT
A form of Ethernet and I EEE 802.3 network cabling
using twisted pair cabling. It refers to 10Mbit/s speed Baseband
transmission twisted pair cable with a maximum segment
length of 100m.
100BaseT
IEEE standard from proposals by the Fast Ethernet
Alliance (including 3Com and SynOptics). It will support Category
3, 4, & 5 UTP cabling.
100BaseVG-AnyLan
A competing proposal to 100BaseT (promoted by Hewlett
Packard, IBM and Proteon among others) to the IEEE for a
100Mbit/s standard over voice grade UTP the cable
most users already have installed in existing 10BaseT systems. Based
on Quartet Signaling and demand priority protocol,
it preserves the infrastructure and will need only a new hub and
upgraded adapters in PCs/work stations. It claims
support for Category 3,4 & 5 UTP cabling for both Ethernet and
Token Ring.
Bandwidth
The range of frequencies a transmission line or
channel can carry: the greater the bandwidth, the greater the information
- carrying capacity of a channel. For a digital channel
this is defined in bit/s. For an analog channel it is dependent on the
type and method of modulation used to encode the data.
Bit
binary digit A bit is the smallest unit of data
in computing, with a value of either 0 or 1. Whenever you see a lowercase b
associated with a number, it's likely to be a bit.
It can be prefixed with kilo- (for 1,024 bits, or to the 10th power) or
mega- (1,024 x 1,024 bits)--and sometimes finds
its way into data transfer speeds (such as 14.4 kbps).
Byte
A byte usually denotes 8 bits (also called an octet
or a word), which the computer treats as a single unit. Longer
sequences like 16 and 32 bits are also possible.
Abbreviated as uppercase B.
Dynamic Host Configuration Protocol (DHCP)
A proposed industry standard implemented in Windows
95 for configuration of TCP/IP and IP address allocation and
management. Assigns a unique IP address to the machines
logging on to the internet.
Domain Name Server or Domain Name Service (DNS)
Which is the method used to translate the name of
a computer (which is easier for humans to remember) into its numeric
IP address (which is needed by any computer
trying to connect to it).
Gigabyte
This year's minimum hard disk size is one gigabyte,
or 1,073,741,824 bytes, which should be enough for Windows 95 and
other modern operating systems--for a few months
at least. Abbreviated as GB.
Kilobyte
Although kilo is Greek for a thousand, a kilobyte
actually contains 1,024 bytes (that's 2 to the 10th power). In other
words, a thousand bytes is actually less than
a kilobyte. Remember that the next time you download a file. Abbreviated
as K.
Megabyte
Although mega is Greek for a million, a megabyte
actually contains 1,048,576 bytes (1,024 x 1,024 bytes). In other
words, million bytes is actually less than a megabyte.
Remember that the next time you buy a hard disk or try to fit files
onto a floppy disk. Abbreviated as MB.
TCP/IP
Some MS winsock parameters:
DefaultRcvWindow = 16-bit number
Specifies the default receive
window advertised by TCP. The default is 8192.
DefaultTOS = 8-bit number
Specifies the default type
of service (TOS) for IP packets initiated by Microsoft TCP/IP. The default is 0.
DefaultTTL = 8-bit number
Specifies the default time
to live (TTL) for IP packets from Microsoft TCP/IP. The default is 32.
MaxMTU = 16-bit integer
Specifies the maximum size
datagram IP that can pass to a media driver. SNAP and source
routing headers (if used
on the media) are not included
in this value. For example, on an Ethernet network MaxMTU will default
to 1500. The
actual value used will be the minimum
of the value specified with this parameter and the size reported by the
media
driver. Thedefault is the size reported
by the media driver.
UDP (User Datagram Protocol)
The IP standard protocol that allows an application
program on one machine to send a datagram to an application
program on another machine. UDP uses the Internet IP to
deliver datagrams.
UPS (Uninterruptable Power Supply)
A battery, attached to a piece of hardware, for
example a server, that provides backup power for conducting an orderly
shutdown if the server's normal power supply fails.
UTP (Unshielded Twisted Pair)
The standard cabling used for telephone lines. The
standard IEEE 802.3, 10BaseT, defines use of Ethernet over UTP
for rates up to l0Mbit/s. The general LAN medium
of choice for the 1990s, UTP is marketed in brands such as AT&T's
PDS (Systimax) and OSCA.
