Make sure in the file '/etc/sysconfig/network' that the line:
GATEWAYDEV=
either doesn't exist or points to a non-existant device.
( I use the non-existent device method, myself )
It get set pointing to your 'eth0' if you answered 'YES' to default
gateway device durning the system install. For which 'YES' sounds
correct but isn't if you are also going to be using 'pppd' to connect to
an outside network.
If the 'default route' already exist 'pppd' will not install one and
this can make it appear to NOT WORK, {unless you add the additional
routing information manully}.

Look at the ethertap Kernel Device or RAW Packet Sockets.
If you only need to send self define IP Packets, then you can use SLIP
attachd to a virtual Terminal.
BTW: on Freefire you can find the Pointer to netlib or fake, tools which
enable you the MAC address Sending. Receiving s a bit more ugly, though...

The only insight I can give you on this is that I use mars OJT and it hasn't
been a bottleneck. My environment is dos 622 connected to a linux server running
"test cases" that take anywhere from 24hrs to 2 days to run. I've optimize our
setup and our bottleneck has been processor and memory related. What I do,
requires alot of network I/O. It is comparable to samba from my perspective.

But here you start sending username and password without waiting to be
prompted for! Dialin using minicom go trough the login and memorize the
output of the server. After this build a better except-Script. The man
page of pppd tells how it does have to be composed. Maybe you have to
send "ppp^M" after successfull login to start the pppd on the
terminal-server.

And that's the result of not being logged in but sitting on the password
prompt. If you would be located before or after the password prompt you
would probably have seen an additional message "link not 8-bit clean".

Subject: Surfboard sb1000 cable modem
Date: Fri, 08 Jan 1999 16:38:32 -0500
I'm using a Surfboard cable modem (a sb1000). It's an internal ISA
jobbie and it's using 1 way downstream with a modem used for uploading.
I've set up the modem to dial out, configured the routing properly, and
have configured isapnp to recognize the isa card.
However, when starting ppp, the modem connects fine, gets an ip address
etc, but there is something wrong with the cable modem...
i get the correct message for the modem being activated in
/var/log/messages
...... kernel: cm0: sb1000 at (0x100,0x000), csn 1, S/N 0x3079fa51,
IRQ 10.
but then get a timeout:
...... kernel: cm0: card_wait_for_ready timeout
does anybody have any advice? has someone seen this and fixed it? all
help is appreciated.

I am trying to convert a win95 box to a redhat5.1 workstation on my
university's net. I am using an ISA 3COM Etherlink III with twisted pair
cable. In win95 the computer has a static ip address and runs without any
problems. I used the same network settings as in win95 for ip, gateway, dns
etc, but the network is still unreachable. Here is an excerpt of my boot
log:
Jan 7 13:31:51 jeffress kernel: eth0: 3c509 at 0x240 tag 1, BNC port,

To look at that, it looks like it is a recognized card and that it's up
and running. I'd have to see the log later (next couple lines) to tell
you for sure, but it looks fine.
eth0 is your first ethernet connection, not the card making the
connection. Type '/sbin/ifconfig' and see if you get a bunch of lines
like:
lo <line>
<line>
<line>
eth0 <line>
<line>
(line>
There will be more lines than that, but you get the idea. If you get
eth0 with anything, it's working.

I have tried many times now to install Redhat 5.1 on my old 486 and
some no-name ethernet (ISA) adapters. I can't ever seem to get it to
find either adapter!
I know next to nothing about Linux/UNIX, and have been using Que's
Using Linux to help me through.
I can get Linux installed, but never is it able to find the ethernet
adapters.
Incidentally, the adapters are from Hawking Technology, and I have no
idea what the "real" brand is as they are unmarked. They are "Fully
compatible with NE2000" according to the box.
I have turned off PNP and have tried a few I/O's and IRQ's, but there
are just too many options.
I have also tried using an AOpen card, but didn't spend much time on
it. I'd rather get the others working!
Please keep your replies simple as I am a newbie to Linux! I know
lots of Dos/Win/NT/OS/2, but that doesn't help here!
I'd also like to have two of the cards in my machine, so that it can
act as a server for my ADSL connection.

I reported before a problem of connection between my labtop and my Linux

with a cable allowing direct connection of the computer to a RJ-45
socket and that I plug this cable to the RJ-45 out of my NE2000

shops close to Tottenham in London. If I exclude the stupids remarks
concerning the fact that I am not able to install the driver and they
can do it for me for �45 !!! or that it's not possible Linux with Win95
! The most raisonable remark was that for a RJ-45 network, even between
two computers, you definitely need a hub. Is that true ? I am a bit

Including the spammers. My problem with that approach is that it

I think the point of the thread was that 'nospam' is simple for a
computer to remove and tedious for a human. I may disagree with the
argument that there are no benefits to munging addresses, but that's
just me...

a) That would involve getting the government in on this, which, given
their general lack of morals, I would rather not do.
b) I'd rather not receive any spam-mail at all than spend all my time
reporting spammers to the cops.
Is there a real solution? Naturally, I can't say for sure. However,
if it -does- become illegal to send spam-mail, people with enough time
on their hands to do so could set up special e-mail accounts designed
specifically to catch people doing so (perhaps by forwarding all
incoming mail to the FCC), and post to usenet with them.
OTOH, I don't pretend to know very much about politics, either in real
life or on the net. I just live with whatever happens, I guess, and
defend myself in the meantime.

All,
Talk about so close yet so far...
I've set up UUCP over TCP using all the info I could find, and I am
running into a strange problem. We've got a PC running Red Hat 5.1,
3com network board, network is uo and running. We can FTP, ping, rlogin
- no problem. UUCP doesn't work.
According to the Debug file, we see and respond to the login prompt, we see and
respond to the password prompt, but we still get
login incorrect. Now before you say I typed the password in wrong,
If I cu to the machine, and type in my login, NO ECHO. hit return,
passwd prompt, type in passwd. waits.....login incorrect.
Rlogin with same user name and passwd works fine.
The important clue is the no echo back when I manually
enter in my login on a cu..........
Any ideas?
