Not sure what you mean by "cable system"? The network is @Home and the
cable modem itself is a 3Com USR CMX.

No. Specifically:
eth0: 3Com 3c905B Cyclone 100baseTx at 0xe400, 00:10:4b:9a:82:e5, IRQ 11
8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface.
MII transceiver found at address 24, status 786d.
MII transceiver found at address 0, status 786d.
Enabling bus-master transmits and whole-frame receives.
eth1: 3Com 3c900 Boomerang 10Mbps Combo at 0xe800, 00:60:97:c8:01:c8, IRQ 10
8K word-wide RAM 3:5 Rx:Tx split, autoselect/10baseT interface.
Enabling bus-master transmits and whole-frame receives.
BTW, dumping the packets from eth1 shows a slew of arp calls, so the NIC is
obviously communicating with the cable modem.

Reason #1: Because eth0 is a 100Mbps device (like the rest of the devices on my LAN)
and eth1 is a 10Mbps device, which is fine for communicating with a cable
modem.
Reason #2: I previously *did* have this card (eth1) working under Linux. I
replaced it with the 3C905 when we went to an all-100Mbs LAN. Having 2
NICs in this box is a first for me, but they don't seem to be in conflict.
I know that the hardware works. The NICs, anyway. The cable modem is
still an open quesion since I haven't yet successfully established
communications with the @Home network through it.
Thanks for the response.

The #com combos ( a majority of the time) have to be the FIRST card
initialized in a mixed card network. i.e. if it is on the server make
sure the server is up and to the login point BEFORE you turn on any
other boxes on the network.
If you reboot server or box with the 3com in it you must also
afterwords reboot all other NE2000 cards.
Ain't 3com wunnerful!

Date: Sat, 22 May 1999 15:16:45 -0500
hi,
ip masquerading is set up as per the HOWTO at
http://mirrors.indyramp.com/ipmasq/ipmasq-HOWTO.html
kernel was compiled as per that doc except without ipautofw
linux host:
address 192.168.1.1
tulip based ethernet card
56k USR modem
windows host:
address 192.168.1.2
3c509b ethernet card
the two hosts are connected with a crossover cable, communication
between the two works fine.
ppp on linux host using diald is setup correctly and has been working
fine
for months. while setting this up i forced the ppp connection to stay
up.
enabled masquerading using these commands:
echo 1 > /proc/sys/net/ipv4/ip_forward
ipfwadm -F -p deny
ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0
also tried changing that second ipfwadm command to
ipfwadm -F -a accept -S 192.168.1.0/24 -D 0.0.0.0/0 -m
(i removed the previous rule first then i did the one above)
i get the same problem with both commands, tcp connections last less
than a minute. i can telnet somewhere on the outside network from
the windows box and i get a login prompt and can login in and run
commands,
but after less than a minute the connection is dropped. same thing
happens
with web pages, part of the page will download then it will just hang.
ftp does the same thing when the ip_masq_ftp module is loaded.
ping works fine, dns works fine.
any ideas?
thanks,
-brandon

Hi all,
I am using Redhat 5.2 with kernel 2.2.5, recently the system reboots
itself a few times without any reason.
At first I thought someone has hacked into my system, but I could not
trace any sign as I checked through from commands such as last and
lastcomm, the necessary log files such as /var/log/message and
/var/log/secure, and crontab.
I disabled other services but only ftp and telnet, and these two
services are controlled by TCP wrappers in hosts.deny and hosts.allow,
which means the box only accept from trusted hosts.
Could it be having some hardware failures like hard disk, IO controller
and etc?
Please advice.

Subject: NE2K-PCI with Redhat 5 fails to initialise NIC
Date: Sat, 22 May 1999 13:40:54 +0100
Hi, im trying to install Redhat 5 (from a magazine coverdisk) and am having
real grief
getting it to talk to my PCI NE2000 network card.
Well i say that, but in the first instance it worked fine, as I did a FTP
install from my
winNT box, and it auto-probed and found the card no problem, and installed
over the
network, but when I came to boot the machine from the hard disk (using
loadlin from dos,
but ive also used lilo from a boot floppy with the same result) it failed to
find the
card. This at least proves I am using the right driver, and the card is
physically fine.
I tried using ifconfig to bring the card up manually, but it says it is
delaying
initialisation of the card, ie
ifconfig
using netcfg from X does the same thing (Yes i managed to get X working
fine, so i am
happy messing with config files - in fact I think thats a much better way of
doing it
that the sodding regestry on MS os's!!)
I also tried directly insmod'ing the ne2k-pci.o file, but it complained of
missing
symbols
(
Unresolved symbol ei_open
Unresolved symbol ethdev_init etc
)
I also read on usenet that you should insmod the 8390.o module first,
()
before loading the module. Again I got missing symbols:
Unresolved netif_rx...
etc
I think maybe it missing some lower level of the network stack, but being
bought up on MS
software (which either works, or needs re-installing...) i would like to be
able to learn
something about Linux/Unix while I fix the problem, instead of taking the
easy way out
and installing a different distribution of Linux
I would be very grateful if anyone who has beaten this particular problem
could share the
solution with me
if possible would you be able to mail me directly at
[EMAIL PROTECTED]
as well as posting to usenet, as my newsreader is a bit crap

You don't really need a route to this host (itself).
I doubt it is causing problems though.

Why is there a '.' after the address? Is this a copy error? Worth

The driver that came with my copy of RedHat 5.2 didn't work for my
3c905b card. I got and updated driver
(http://cesdis.gsfc.nasa.gov/linux/drivers/3c509.c which contains the
905b driver too) from http://cesdis1.gsfc.nasa.gov/linux/drivers/ and
achieved happyness.

Did you try to set the firewall timeouts to higher values? I think the
parameter was ipfwadm -S with three numeric parameters appended. Check out
the man page on that...

Did they have computers in 1979? ;) Anyway the date, if true, may mean
that the device file is damaged in some subtle way or that the ioctl

file; does ls -l /dev/modem point to /dev/cua1?
You can make new device file with mknod, man mknod. The major and minor
device numbers, 5 and 65, are correct. Addition insight into device
files is found in the files /dev/DEVICES and /dev/README.MAKEDEV.
Oh yes, just to forestall anyone posting a remark about it, the kernel
powers-that-be say to use /dev/ttySx and that /dev/cuax will not be
supported someday. However, even the newest kernel from the 2.2.x line
will still use them - although they complain about it in a log file.

By proxy, do you mean a network proxy, so that internal machines can
access the net THROUGH this machine with the static ip? If so, that's
easy, and it's call IP Masquerade. Look below for a great site on
