Date: Wed, 8 Sep 1999 13:58:09 -0400
Has anyone had any experience using linux on Media One Road Runner - south
east region?
I can not get linux to get an IP. I know my NIC is fine, because if I put
my windows machine and my linux machine on the same subnet I can ping back
and forth and I can telnet into my linux.
Media One claims it should work, but I have found a couple How To's that
claim Media One does not use a standard DHCP and has caused problems.
Any suggestions on where to go from here? Anything else I shoud test?

Subject: Good Documnet for setting up ADSL
Date: Wed, 08 Sep 1999 22:17:20 GMT
Greetings,
My ISP started ADSL service, but they said Linux won't be supported
because they haven't tested on it. ISP said Linux will be supported by
the end of October(hopefully), and I could try to install it myself if I
really wanted to.
If I want to do this by myself I'll have to spend $40 whether I succeed
or not since there is no trial period. I was wondering if there is any
good document that I could look at; so that I could install it on my
Linux Box by myself.

OK.
And what if there are several questions you are replying to
in a single message? Do you then type all your responses at
the top and expect your reader to keep referring back and
forth to the original questions at the bottom to figure out
what it is you're responding to in your answers? Yuck!
It seems to me easier to handle each question separately;
quote the question first, then write your response, then
quote the next question, write your next response and so
on.
And no, you don't need to quote the entire original letter
in your response. You edit out all but the specific issues
you are responding to, leaving only enough context as is
required to present the question in sensible and undistorted
terms. You may also paraphrase, perhaps in square brackets,
to keep excessively verbosity under control or recast
poorly written question in a more sensible and concise
light. This was especially important in the old days of
usenet, when it was transported using uucp over dial-up
connections and pay-by-the-minute long distance charges.
Now that usenet is transported over the internet nobody
seems to give a rip about bandwidth concerns anymore, but
that's another issue entirely...
This seems to have been a "de facto" convention for as long
as I've been using usenet and BBS systems, going on 12 years
now...

Win9x includes a telnet client but it's nothing special.
Try Kermit95 from the kermit project at Columbia
University. It's one of the best telnet clients available

Subject: Re: Two boxes connected to same hub (with cable modem), different subnet
Date: Wed, 08 Sep 1999 19:13:47 -0400
I know I could go this way, but I'd prefer my current setup for the following
reasons:
1) I'm not "technically" permitted to do this by my cable company (I know, I
know, there's no way of them finding out, etc., but it's harder to get tech
support when you're doing stuff you're not supposed to. Not that they support
Linux anyway...)
2) I'd need an extra box and two extra NIC's. I realize I can use a dirt-cheap
box (486) and NIC's don't cost too much these days, but they aren't free.
3) My current setup is, well, already set up, and I'm kind of lazy.
I've heard that I can play with the static routing tables on the Linux box,
although I'd have to change them each time my address changed via DHCP. I
just want my two boxes to talk to each other through the hub... :(

FTP is probably the best way to guage transfer performance. PacBell's
response does seem *lame*, but I bet they can get away with it :-(.
However, if your ISP is anything like mine, you might have a good way to
test. I assume from your message that you were transferring files to/from
somewhere in the 'world'. If you have some web space with your ISP, just
do the transfers to/from there. If not, talk to your ISP, tell them what
you're trying to test. I'm sure they will be helpful. They probably even
have files to download from there website. Ask if they have a web page
caching server. If you pull something from there, I'm sure it will take
any ambiguity away fro mthe 'world' part of the equation.
Good luck.

Not only that, but IPChains as well, so you can set up minimal
firewalling rules, to block connections or attacks from a certain site,
to a certain port. But, DEFINITELY get TCPWrappers working. they will
help you a lot. You may want to check into the Linux Administrators

Hum, maybe that's my problem. I was using RH5.2 and it worked fine. I just
upgraded to 6.0 and DHCP won't get the default gateway from Mediaone
(Suburban Chicago). It get everything else. So, I manually put in the gateway
address. That's only fine until I move to a different network.
BTW, my NT side work just fine.

I don't really know. (I don't think so, not for simple setups.) If you
want to keep it you could always add rules to your filewall similar to
the ones you have already but to stop outgoing stuff as well. You
certainly don't need WINS outside of your local network...

Subject: 95 on Token Ring segment loses route to net???
Date: Wed, 08 Sep 1999 14:55:39 -0400
Here is the setup that i have
====================
Router eth0 (internet) --ISP
eth1 (lan) ---Various boxes
tr0 (lan) ----Various boxes (Win 95 loses
route to eth0, although NT is fine)
===================
This router routes traffic between the ethernet and token ring segments
and also from the lan segments to the internet via ipmasq. The weird
thing is that 95 clients on the token ring side randomly lose the route
to the internet. No problem seeing the ethernet segment though. I can
not find any errors or anything. Does anyone have any idea as to what
could be causing this problem? NT boxes are just fine. They never lose
the the route. I was thinking something maybe something with 95's
tcp/ip handling?
Thanks in advance for any assistance.

The connection messages looked like you made two good connections. Do
you have /etc/resolv.conf configured with nameservers? man 5 resolver.
Do you have the pppd option defaultroute? Otherwise you can try adding
the pppd debug option (using whatever is equivalent for the kppp frontend)
to get more detailed debug messages and see what the logs look like then.

Your -D_KERNEL_ s/b -D__KERNEL__; note that it is "2"

just remove it. The compiler seems to give some erroneous

Hi There,
I've just installed RedHat and though most things seem to be working
well, I'm having some major difficulties with networking.
I've run linuxconf and netconf a number or times (like 2 million)
and checked and double checked my configurations a million times and it
all seems to be in order.
My machine is Mtl-Linux.montreal.hcl.com. I can ping the machine
itself, either by name or by IP address and it's successful. I can ping
my network (xxx.xxx.xxx.0) but I can't ping anything else!!
Does any one have any idea what I can do? I've already applied the
networking kernel patch and recompiled the kernel but still nothing. I
can't download or get any other patches or kernel updates since I'm not
able to get connected to the network. The killer of this is, I had it
working yesterday and then after I rebooted, it stopped working.
Thanks in advance.
