RE: Dual NIC Problem
Sorry I have taken so long as well. I got pulled onto another project. Yes, I have both configurations in /etc/network/interfaces. The only difference is that eth1 is on a different segment so the only number that is similar between the two NIC is the subnet mask. This is what I have (number are fictisous): iface eth0 inet static address 172.30.14.171 network 172.30.14.0 netmask 255.255.254.0 broadcast 172.30.15.255 gateway 172.30.14.2 iface eth1 inet static address 172.30.12.219 network 172.30.12.0 netmask 255.255.254.0 broadcast 172.30.13.255 gateway 172.30.12.2 Now, I am using 3Com 3C905B NICs. I think I am going to swap them out for some Intel Pro/100s and see what happens.

RE: Dual NIC Problem
Thanks, for the advice. However I did notice that I do not have /etc/init.d/networks file. I have a /etc/init.d/networking file. I noticed this when I first started looking but thought that the file names might have been changed between Debian 2.1 and 2.2. Do you know, or anyone for that matter, if that is the case? Or do I have a botched installation?

Re: Dual NIC Problem
This did change in 2.2. /etc/init.d/networking has replaced /etc/init.d/networks, although a normal upgrade will still use the old one (i.e., the symlinks to /etc/rc*.d aren't created if /etc/init.d/networks exists).

RE: Dual NIC Problem
Well it sure didn't take to long to reach the limit of my knowledge. I really don't know where to look to find what services are running. I found a /etc/services file but that looked more like porting information (telnet 23/tcp). I could not find anything that had the a telnet 127.0.0.1 110 line. Sorry, I am a new user. I am trying this as work and we are on an ethernet network running TCP/IP on class b numbers. There are only two Debian machines on the network right now. Both are purely experimental at this point. I did check the hosts file at it does have the machine name and IP number. When I said I could ping I meant I can the IP address not the device name. I don't have anything set up for name resolution right now for these machines. We are basically an NT VAX shop. The second experimental machine that has only one NIC card I can telnet into just fine without any problems. In setting up the second NIC card on the first machine I could not find much documentation so I just decided to edit the /etc/host file and added another line with the same device name and a second IP address on another segment. Then I went to the /etc/network/interfaces file and added a iface eth1 inet static section defining the IP address, netmask, network, broadcast and gateway numbers. That all I did. I could not find much more information in the How Tos, online documentation or SAMs Debian Unleashed book. I am sure I have missed something. In any case thanks for the help and I hope I have provided enough information to fuel an answer.

Dual NIC Problem
I am a new Debian (2.2) user and am trying to set up an Intel machine for two NIC cards. One NIC will monitor (tcpdump) one ethernet segment while I telnet into the machine on the other NIC on another segment. eth0 is on the segment I want to monitor. eth1 is the one I was planning to telnet into. The problem is that I do not get a login prompt when I telnet into the device, I get a telnet prompt. If someone could point me in the right direction, either to some written resources or advice, I would greatly appreciate it. Thanks, Brian
