i am a linux newbie trying to set up my home lan to share a dsl connection. The problem is linux (redhat 7.1) doesn't seem to be recognizing my second ethernet card (the one connected to the hub). When i go to the kde system control it shows both my linksys LNE100TX and the second one EN-1207D and says they are both operational. But when i go to information --> pci under the control center it does not list an irq for the second card. When i run dmesg i get this:
Linux Tulip driver version 0.9.14 (February 20, 2001)
PCI: Enabling device 00:09.0 (0184 -> 0187)
PCI: Found IRQ 11 for device 00:09.0
PCI: The same IRQ used for device 00:07.2
eth0: Lite-On PNIC-II rev 37 at 0x1400, 00:A0:CC:E1:C6:53, IRQ 11.
PPP generic driver version 2.4.1
and earlier:
PCI: Found IRQ 11 for device 00:07.2
PCI: The same IRQ used for device 00:09.0
usb-uhci.c: USB UHCI at I/O 0x1060, IRQ 11
i dont see "eth1" anywhere.
i am very new to linux so i apologize for my ignorance, hope someone can help me.
If you have "PnP OS" on in your BIOS, turn it off.
Are there entries in /etc/modules.conf for these cards?
If the drivers are modules, it should do with two lines like this example:
alias eth0 tulip
alias eth1 tulip
Now try "modprobe ethX" then "dmesg | grep ethX" for each interface number X.
i'm sorry, i should have posted here to tell you all that i got it straightened out. But now i still cannot get the internal MASQed machines to connect to the internet. I can ping them from the linux box, and the linux box (both NIC cards, no less) from the Windows machines, but that's it. Any suggestions?
1. Did you set the Gateway address on the Windows boxen to point to the appropriate NIC in your Linux machine?
2. Can you can ping addresses outside your network? Try 204.71.200.74 (Yahoo). If you can ping, but can't use URLs, check the DNS settings on the Windows machines.
This non-pinging means your Linux box is dropping MASQ requests. I'd suggest www.linuxdoc.org and looking for the MASQ howto, or optionally for iptables use netfilter.samba.org for this version of masquerading. This topic encompasses quite a bit of problems, but the heart of it is that your linux box is not forwarding packets to the internet like it should.
