oops, sorry for the subject confusion. My faux-paux.
Here's what I do: I start ntop as a service at boot. In my /etc/ntop.conf
file I specify the interfaces (eth1, eth2) to listen on with the -i flag. I
do not assign addresses to the interfaces I listen on. In this case, ntop
brings the interfaces up without IPs. If I shut one down with ifconfig, I
have to reboot the machine to bring it back up; ifconfig will not bring it
up w/ no IP. So my ifconfig output ends up looking like this (just to prove
I'm not making this up! ;-) ):

I have tried that, and I also tried a different OS, I had fedora, I
tried SUSE 9.1, also RedHat 9. All seem to have the same issue, without
an IP, the interface does not come up, at least where NTOP can see it.
I do not think this is an NTOP issue, but a Linux question. Does anyone
know how to bring up the interface without having an IP?
