thanks mr nath,
but how come this would have been done ? if seems i don't have a choice but
to reinstall and resetup. is it possible to reinstall the damaged area as
reinstlling and resetup will be big problem for me.
i am using this server for NAT/RAS/DNS/DHCP/PROXY/WEB services. i am using
ipchains and setted masq on ppp and eth1 ports to allow to use this box as
gateway to some users as rest use proxy settings.

only recently we have started using cable internet and got one ip. could
this has helped the hackers ? earlier we were using diapup connectivity. if
possible please help me and tell as what precautions should i take to keep
away the hackers.

 i will let u know what u have asked as right now my system is in use by
users as rest everything is working except login. and see all details i have
to boot it to linux single.

thanks
km
