Reply-To: [EMAIL PROTECTED]
I read the other posts about the 3c905b problems. I'm dealing with
Slackware and the same card. I've seen the 3c9x.c (I think that's what
the name of the piece of source code is), but I don't really know what
to do with it.
(If I could get this 905b card to work with the win98 machine, I would
use its 3c905 --!b-- card in the linux box. It boots without a single
glitch)
I tried rebuilding the kernel, but got sprayed with so many errors, I
wouldn't even know where to start debugging. So, I'm using the
/sbin/modprobe 3c59x. It just comes back and says that my card doesn't
have support and I should edit rc.modules (which is where I load the
module) or re-compile the kernel...Tried both...nothing doin'.
What it boils down to is....If I get the code for the new driver, 1) How
do I compile it? 2) Is it better to use modules or compile the kernel (I
only have 16 MB RAM in this box, so I'm currently opting for modules)?
3)Is there a URL/site with good directions/troubleshooting helps on
re-compiling the kernel?
Thanks,
Jason

Hi,
I have a network of Windows machines connected to the internet by a
static modem line through my linux box running kernel 2.0.36. Before
this, the gateway was a very unreliable WindowsNT Server machine. Email
was handled through a program call MDaemon. Any mail to my domain
(ldcglobal.com) was sent to my ISP and queued there. MDaemon would send
the string "ETRN ldcglobal.com" to the ISP's mail server and the ISP
would release the queue of email to MDaemon. Users then could check
their individual accounts through any POP3 mail client. MDaemon does
not work through IP Masq through the linux box. The mail queue never
gets released. The string is sent and received, but no mail is ever
sent back. My question is how do I get MDaemon to work through IP Masq
through the linux box _OR_ how do I set up the equivalent of MDaemon on
the linux box with users being able to check their mail with a POP3
client? Any help is really appreciated.
Thanks,
Ben

You could buy the NFS package for Netware and the Linux Server will show
up in your tree. It is fairly expensive though.

Subject: Telnet daemon problem fixed
Date: Tue, 16 Mar 1999 19:29:59 GMT
I have been having a most annoying telnet problem in my Linux box,
and although I have noticed that I did not seem to be the only sufferer,
fixes for it did not seem to be forthcoming. Thanks to hints from
members of this forum I have fixed it myself, and would like to share
the fix with the rest of you guys.
The problem: I can do telnets only in loopback. Any other incoming
telnet calls are rejected, the caller never getting the login prompt.
The platform: Linux 2.0.33 in a Slackware distribution (I forget
which version, sorry about that.)
Items to watch: Make sure that /etc/hosts.allow and /etc/hosts.deny
are not blocking incoming calls themselves. Make sure you have your own
IP address in your /etc/hosts. Make sure that your inetd daemon knows
about the in.telnetd daemon in its configuration file.
The fix: A radical one, consisting of downloading and compiling the
in.telnetd daemon in the netkit-telnet-0.10 package. When doing so make
sure that you have an up to date version of the ncurses library (which
you can also download in source code form). When configuring
netkit-telnet-0.10 the configure script fails to detect the ncurses
library, even if it is correctly installed (at least this is what has
happened to me). This is because of the following line in the configure
script:
$CC $CFLAGS $WARNINGS $LIBS -lncurses __conftest.c -o __conftest >
/dev/null 2>&1
Changing it to
$CC $CFLAGS $WARNINGS $LIBS __conftest.c -o __conftest -lncurses >
/dev/null 2>&1
allows the configure script to detect the ncurses library all right
(assuming it is correctly installed, of course).
The resulting in.telnetd executable works as expected, offering the
login prompt to incoming telnet calls, assuming that the remote side is
not subject to restrictions imposed by a firewall or some other security
mechanism.

Apparently, there's a package called Mars_NWE that provides a Netware Server
emulation. As for Netware client support, get the ncpfs tools and enable
the ncpfs support in your kernel. With these, you can client mount Netware
servers to your Linux file system hierarchy.

I posted this same question a fews weeks ago. I ended up getting a Netgear
DS108 8-port 10/100 hub for $154 from www.buycomp.com. Basically, the 10/100
dual speed 8-port hubs are an n-port 100-baseT hub and an (8-n) port 10-baseT
hub with a switch between the two. So 100bt packets stay away from 10bt segment
and vice-versa, unless:
1) the destination is 10bt and the source is 100bt
2) the destination is 100bt and the source is 10bt
3) it is a broadcast packet.
A very clean solution, without the hassles of routing netbios/appletalk traffic
between the two eth cards. I put a spare NIC in the Linux box, though, and plan
to try fiddling with your other option of routing between two single-speed hubs,
for educational purposes. For simplicity, though, get the dual-speed hub.
Later on, you can plug fast ethernet hubs and normal 10bt hubs into the
dual-speed hub to expand your network.

Subject: Re: 2 LAN Cards: delaying eth1 initialization
Date: Tue, 16 Mar 1999 04:22:41 GMT
Tricky little bugger - I found the answer in one of the HOWTO's.
To get 2 identical cards (that is 2 cards that use the same
driver) reconginzed you have to run linuxconf and set the IO and
IRQ of each eth0 and eth1 to both! OK to summarize:
eth0
ne < -- I'm using NE2000 driver.
IO 0x280,0x300 < -- Yes set IO= both addresses separated by
comma.
IRQ 5,3 < -- Yes set IRQ= both IRQs separated by comma.
eth1
ne < -- I'm using NE2000 driver.
IO 0x300,0x280 < -- I don't know if you have to switch order but
I did
IRQ 3,5 < -- and it seemed to work.
That will work! I Too am trying to get an @home IP masquerade
working but have yet to succeed. I did get past the NIC card
problems however.
I can PING the outside world from my LAN machine but can't browse
out there yet.
Also, for some reason sendmail is running on my Linux box and
take about 10 minutes to boot! How do I turn off sendmail? I
already have mail provided by @home. Don't need another mail
package. (do I?)
Good Luck,

Hefin,
Our current system is dual P2/350MHz on a SuperMicro P6DBS board, runs
great. We are using the intel pro/100, it also is great. We run a
distributed Oracle database and not a lick of problems. Averaging over
10GB/wk between the servers without a problem.
The local
university has 6 linux servers, including a full feed news server, all
using the intel card on dual
pentium/233s and have not had one problem. Very stable.
Good luck,
Daniel

are you saying that
1) gateway machine used to refuse direct root login from telnet.
2) someone hacked into your box.
3) you can now directly login as root via telnet.
did you reinstall the complete system between 2 and 3? you will need
to, since all manner of things may have been corrupted. a fresh
install is the only way to be sure everything is gone.
if you did reinstall, maybe it's a configuration. redhat, for

We are using a 16MB 486dx2-80 as a firewall/router/gateway between

a 56K modem to our ISP at the same time. The linux box is using less than
