I added an IP (IPs changed for this example): ifconfig eth0:1 192.168.197.179 netmask 255.255.255.128 up
It was listed with "ifconfig -a". Then I removed it with: ifconfig eth0:1 192.168.197.179 down And it was gone (not listed) from "ifconfig -a". But I can still ping it from a remote machine and logon to it. Then I tried to reset eth0:1 by giving it a different IP, but the old IP still worked. And I tried (as documented in linux/Documentation/networking/alias.txt): ifconfig eth0:1 down Any ideas on how I get it to stop listening to that IP ... I found a way: I assigned the IP to eth0:4, then I assigned a different IP to eth0:4 and then it was gone (and I couldn't connect to it). Any ideas why I could connect to an IP that wasn't listed by ifconfig? Can anyone reproduce this? This is Debian 2.2 Linux 2.2.14. Jeremy C. Reed
