Some links that can point you in the right direction, they are excellent
sources of information for networking windows and your RH box:

Subject: Direct ethernet connection under Linux
Hello everyone,
I get a problem with ethernet connection under linux:
I want to connect 2 laptops, both equipped with PCMCIA 10/100BaseT
ethernet card. So I took a cross-over cable (not the normal twisted-pair
one)
My setup is the following:
IP=130.60.93.222 resp. 130.60.93.223
Mask=255.255.255.0, Broadcast=130.60.93.255 (for both hosts)
Under Windows98, it's no problem, both cards detect a 100Mbit/s mode.
(The actual transfer rate is lower.)
When I booted ONE host to Linux, ethernet cards can still detect
100Mbit/s mode, but there is no connection available. Then I pulled out
this crossed-over cable from the linux host, connected this linux host
with normal twisted-pair cable to our switch, (without reboot and
changing any network information), it can problemlessly connect to
internet
(ping, ftp, telnet...).
When both hosts booted to Linux, there was still no improvement, ping
showed
no response from the other host.
/var/log/messages tells me
kernel: eth0: Setting full-duplex based on MII #0 link partner
capability of 41e1.
The ifconfig command tells me
eth0 Link encap:Ethernet HWaddr 00:60:08:B5:73:E2
inet addr:130.60.93.222 Bcast:130.60.93.255
Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:99 errors:2 dropped:0 overruns:0 frame:2
TX packets:44 errors:0 dropped:0 overruns:0 carrier:44
collisions:0 txqueuelen:100
Interrupt:10 Base address:0x100
Does anyone have an idea what I configured wrong under Linux?
BTW, Linux version I use is Mandrake6.0 and Redhat6.0.
Thanks a lot!

Subject: Share an Internet connection?
Date: Mon, 16 Aug 1999 11:28:41 GMT
This might be a duh question, but I'll ask anyway.
I have two machines networked -- connected directly with NICs and cable.
One is running Linux Redhat 6, the other NT4 wkstn. I use the Linux
machine primarily as a webserver, and generally for learning Linux. Both
are configured with dial-up Internet access. Samba is installed and
working.
Can I configure things so that if I connect to the Internet via the NT
machine I can also access this connection (while its up) from the Linux
machine? Right now the Linux machine communicates fine with the NT
machine but doesn't "see" an Internet connection when the NT machine is
dialed-in. I have to disconnect the NT machine and dial-in from the
Linux box.
Any suggestions appreciated, but please go easy with this beginner (it's
amazing I got this far on my own!)

Just a thought here,
Have you disabled all the Power Saving stuff in your BIOS? I have had
similar problems with Linux in the past and found it does not work well with
this stuff enabled. Especially with the Wake on LAN type of NIC cards.
Again, just a thought!!

Can I interpret this correctly as saying that I cannot use Win98 as a PPTP
client (behind my Linux firewall) to connect to a PPTP server (outside my

Hi Folks,
Sorry if this is a little OT ... please redirect me if I'm off base.
I need to know the difference between running a job in batch mode and
running it from a prompt. I have an executable file and, if I'm logged in
as root and start the job, it gets so far and craps out. If, however, I
submit it as a batch job, it runs to completion.
I'm probably missing something simple ... suggestions?
Thanks,

Has anybody ever configured a Frame Relay modem?
They usually use a router with an internal IP and I would like to use my
linux box straight.
Such modems have 25 pins parallel like connexions to the router and then
RJ45 to the hub/machine connected to it.

Try quoting the string: '\rAT&F&B1&A3E0Q0V1&C1&D2S0=0'
Without quotes the "&"s on the chat argument list have special meaning to

That \rAT in the original script should be quoted too. It has been

If that doesn't cure "nothing works" then post exact log messages,

I need to qualify this a bit. In the past pppd has not returned the
ttySx parameters to their original state and this denied access to some
programs, notably stty but perhaps chat too. It was annoying enough
that I patched pppd so it would reset ttySx properly. I *think* that
ppp-2.3.9 (the latest pppd package) resets the parameters correctly.
If you have minicom then you can execute it and then immediately exit
with Alt-q . Minicom can access the ttySx after pppd and it sets the
parameters so that ttySx can be accessed by stty after an Alt-q exit.
This may also work to allow chat to access the ttySx and the suggestion
below to work.

Just a hunch where your problem might be..:-)
Are both NIC under win installed as PNP?
(Unless of course you are using kernel version 2.2.10, it has pnp support,
but you have to compile it into a new kernel....:-)
If your cards are PNP this _could_ cause some problems under Linux....
if they are already installed as non-pnp devices..... sorry I can't help,
since I'm new to linux myself....
but if they are installed as PNP ( most of them are) you should disable PNP
on the cards, (look into your floppy for a help or readme-file. After you
disabled pnpray, then you have to install a non-pnp driver under WinXX,
(take the driver from the floppy,)
One last chance to make it work is the Bios, there change the IRQ for the
card from pnp to a non-pnp......

I have a similar problem with a new SuSE 6.1 installation. After
posting my logs on another newsgroup, I got the following response:
If your host is a BSDI system, it may apply to you as well.
==========================
Date sent: Sat, 14 Aug 1999 00:04:56 -0700
From: Vilmos Soti <[EMAIL PROTECTED]>
I had exactly the same problem, and my ISP also used BSDI. I
finally tracked down the problem that the first frame's starting
character, a "~", coming from the ISP, was missing. Try enable
complete logging (So you can see what's coming from the wire)
and decode :-) it. I couldn't find a solution and was forced to
use a different package.
One way to check out if the opening "~" character is missing is
to logon to your ISP through minicom or seyon and login to PPP.
See if the first printable character in the ppp garbage (full
with "}") is a tilde. If not, then you have the same problem I
had and I don't know any solution. I think the problem is on the
BSDI side. My ISP's tech support was a nice person and logged
into his account through HyperTerminal and sent me the output.
The frame opening tilde was missing there, too.
Here it seems the Linux TCP/IP code ignores the incomplete frame
(and causes headaches) but the Windows one (I used WIn95, long
gone from my machine...) "recreates" the missing info.
