hi,
i have one ethernet with 3 ip addresses...

root# ifconfig shows (think the word vsnet0 is same as eth0 only i'm running in vps)...
venet0:0 = 75.126.18.81
venet0:1 = 75.126.18.82
venet0:2 = 75.126.18.83

i have 4 linux users:
root, user1, user2, user3

i want when user1 is logged in (through ssh or direct) then user1 can use 75.126.18.81 for internet related programs,
user2 use 75.126.18.82
and user3 use 75.126.18.83,
etc...

is this possible (i'm using CentOS 4.4 and have no GUI)?

Check out IPTABLES tutorials..you can filter upon username or ID...so block traffic for the user in question except for the interface you want him to use.

the thing i am trying to do is i want to run one application (say bittorrent for example) on the first ip, and then i want to run a second application (like limewire) on the second ip, and another application like an emule client on the 3rd ip.

right now they all want to run on the first ip (on different ports so it works) but i want them to run on different ips.
any suggestions?

Need to set up three different Networking files. One for each user (user1, user2, and user3). Each user would be on a different I.P. ( user1 on [75.126.18.81], user2 on [75.126.18.82] and user3 on [75.126.18.83] ). Try using a shell as "root", and editing the files after creating them. Remember to save all the files that are created, and also save all the files that are modified. Good luck.

the problem is these network config files seems to reset to defaults when the machine is rebooted.
the machine is a VPS (dedicated server) by the way.
