Subject: Help! Multiple ethernet config problems
Date: Sun, 17 Jan 1999 22:00:16 GMT
I am trying to setup a 486/50 computer with multiple ethernet cards to be
used as a firewall and am having all kinds of trouble getting both cards to
work at the same time. The cards in question are a (ISA) 3Com 3C509B and a
Linksys Ether16 using the 3c509 and ne modules respectively. I have
configured both to non-pnp via their Dos utilities and configured a kernel
with modular drivers as well.
The problem is that even though both cards appear to be initialized at boot
and will show up as active via an ifconfig command, I can only ever ping one
of the cards at once (from the box that they are installed in). Via
Linuxconf, I have setup the adapters with the io and irq information and have
introduced the parameters via lilo as an append statement also. Given that
either one card or the other can be pinged when I change the io and irq for
the card I am suspecting that it is a resource configuration issue. The
problem is that there are, obviously, a huge number of io and irq
combinations and I would like to try a better method than trial and error to
find the right combination.
The last combination I tried was eth0 at io 0x320, irq 5 and eth1 at io 0x340
irq 10. Other unsuccessfull combinations have included 0x210, irq 10 and
0x300, irq 5.
If anyone could offer any advice I would really appreciate it. I've spent a
ridiculous amount of time trying to find a solution! :-)

After a great deal of heart-ache I finally got linux to detect my
ethernet card properly and thought that was it, but oh no the tale of
woe continues......
(Thanks in advance to those who read this and help me out).....
My installation:
486 PC with pentium overdrive running SuSE Linux
Acorn RiscPC (StrongArm) running OS
Intel PII running windows 98
Linked on a network via a hub.
All network card have 1 port only (I'm not trying to use the 10base2
connector on a 10baseT network is what I'm saying)
THE PROBLEM:
whilst the two non-linux machines will happily 'ping' one-another and
exchange files, the Linux machine won't 'ping' either of the other two,
nor respond to being 'ping'ed itself.
A CLUE:
after setting the machine to ping another machine on the network, and
going off and reading the net-3-HOWTO and then coming back and
cancelling the 'ping' and checking out 'ifconfig' I get this output:
lo link encap: Local Loopback
inet addr: 127.0.0.1 Broadcast:127.255.255.255 Mask:255.0.0.0
UP BROADCAST LOOPBACK MTU:3584 Metric:1
Rx packets: 1087 errors:0 dropped:0 overruns:0
Tx packets: 1087 errors:0 dropped:0 overruns:0
eth0 link encap: 10Mbps Ethernet HWaddr: 00:20:18:35:20:BE
inet addr: 192.168.1.1 Broadcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Rx packets: 0 errors:0 dropped:0 overruns:0
Tx packets: 0 errors:0 dropped:0 overruns:0
Interupt:9 Base Address:0x300
To me this suggests that the machine is trying to 'ping' through the
loop back and not the ethernet card. (I could be wrong, I often am)
If any of you guys can help that'll be great as I've really got stuck on
this one,
Cheers,
Sam

Thanks for the input on the ipfwadm. I tried the command you gave, but
it didn't seem to work.... I've checked out the howto, but it doesn't
give anything (that I saw) on masquerading, which is all I'm interested
in now. How can I check that it's set up correctly? namely,
1. How to verify the kernel is ok with forwarding and masquerading?
2. How to check the forward and masq rules
3. How to test the system.
I tried testing it by pinging to an internet address from my LAN, to no
avail. I have NT on the LAN set up so my linux box is the default
gateway. Any suggestions?
thanks

You can try and manually try out several modules. Assuming default
installation,
they are located in /lib/modules/2.0.36-xxx/net.
use the modprobe command to try out several modules.
--modprobe eexpress.o. If it can't locate the card it gives an error.
try until you find the module that'll fit. Then insmod <modulename>
Check the files /etc/sysconfig/network and /etc/conf.modules.
Then use the ifconfig command to set IP adress and such and bring it up.
read the man page of ifconfig for this.
If you want to use the GUI configuration tool you may have to
give the right address and/or Irq when adding the card. Such as io=0x300 irq=11
(or whatever applies to your card)

Here is the suggested way and it works for us:

Read the following how to's on cable modem and dhcpcd (dhcpcd will
asign an ipaddress to the network card connected to the cable modem)
BTW, works great but just a little concerned about security and being
connected %100 of the time.

I had the same problem with Redhat 5.2, but SuSE 5.3 worked fine, probably
because it had a slightly updated kernel. Did you try the Redhat boot image
in the updates directory?

I had this problem.Me too I had an answer from this group.
U should type (or add those 2 lines in your rc.local)
route add 192.168.1.1
route add -net 192.168.1.0 netmask 255.255.255.0 eth0

Subject: Linux and winNT callback ... PPP doesn't work.. why ?
Date: Sun, 17 Jan 1999 19:46:41 +0100
hi,
I configured my linux box to connect to a NT RAS server with the callback
abilities. I know I get authenticated the first time. (I call my server, it
authenticates me .. and it call me back)
My modem answers the call, and around 30 seconds later, my modem hangs hup
and it seems there wasn't any ppp device created
Here follow the log of my connexion :

I believe the ftp.exe that comes with Win95 is a diret port of the
standard Linux ftp program.

Subject: Very nasty networking problem!
Date: Mon, 18 Jan 1999 02:32:04 GMT
This has been going on for months now.
When I first boot the system (slackware 3.5, 2.0.34 kernel) everything
is fine until I connect to my ISP. After a couple minutes to a couple
days my linux server can not connect to ANYTHING anymore (telnet,
fetchmail, sendmail, ftp). I cannot even telnet to the localhost! I
CAN ping everything so resolving an ip is not a problem.
Disconnecting from my ISP does nothing. I have to do a REBOOT to fix
the problem.
I have reinstalled/upgraded to the next version of slack, even
upgraded the motherboard, ethernet card, memory, also tried different
ISP but same problem. I use my same installation media for my MANY
customers, same configuration and many of my same scripts and they
NEVER, NEVER have this problem. I inow this maybe a tough one since I
have heard of only ONE other person with this problem.
PLEASE HELP, I mean PLEASE HELP!

Yes, it seems you have to recompile the kernel 2.0.x,
since some vendors forgot about some options in the networking
sections - so masquerading does not acutally work. Maybe
you want it to be built directly into the kernel.
But, well, you didn't tell of the osrelease - just in case:
the 2.1.x kernels use 'ipchains' for administration of
masquerade/firewall, not 'ipfwadm'. It's been my fault
some time that had been causing me some serious headache.

Subject: RedHat Linux 5.1 & Ethernet 3c509 NIC
Date: Sun, 17 Jan 1999 16:40:59 -1000
Reply-To: [EMAIL PROTECTED]
Hello,
I have 2 computers running RedHat Linux 5.1. The Pentium II runs fine
with an NE2000 compatible NIC. The 80486 with 3c509 NIC, however, does
not initialize eth0 and ifconfig only shows loopback. Here are the
specifics:
At boot:
(1) First error message:
Finding module dependencies: conf:2:missing module argument
/lib/modules/preferred/modules.dep does not exist
I checked and the file modules.dep does exist in the directory
specified. I'm not sure if this has anything to do with the NIC
problem. I don't know what other types of problems might occur because
of this. I'm not sure why it's having trouble with this file. It looks
like an ascii file.
(2) The second message:
Delaying eth0 initialization
When I look at eth0 after bootup, it is not active. I activate it and
restart the network daemon. ifconfig shows only loopback. Is there a
way I can initialize eth0 at the command line, activate it, restart the
network daemon and get this to work? Should I load RedHat Linux 5.2?
Should I get another NE2000 compatible NIC? (This NIC worked fine with
Windows 95.). I have all of the ip address and host information in the
databases. It doesn't like it when I specify the ioaddress and irq, so
I took that out. Are there any other diagnostic utilities I can run?
I appreciate your time and any suggestions or references to resources
you can point me to.

I don't think so. It's not the ethernet card that gives the ping replies,
its the kernel (or ip stack). When you ping the ip address of the card,
the kernel looks at the ip address and says, "hey, that's me" and replies
directly. The kernel doesn't have to ask the card to do anything.
Hope this helps.

From: Nick Papadonis <[EMAIL PROTECTED]>
Date: 17 Jan 1999 22:03:13 -0500
I haven't found a entensive online FAQ on this, so I thought
it might be a good question for this newsgroup.
I have heard the following on EQL Line Load Balancing:
If ppp0 interface is connected to an ISP
and If ppp1 interface is connected to an ISP
I can use both to get double throughoutput???
Can the connections be on different provider's lines?
Does my ISP have to know about this, and why??
Any insight or stories of past EQL experiences is
much appreciated.
