why not try it for yourself.

    http://www.vergenet.net/linux/fake/

    Fake allows you to take over the IP address of another machine in the LAN
    by bringing up an additional interface and making use of ARP spoofing.
    The additional interface can be either a physical interface or an IP alias.


fake is integrated on heartbeat (linux-ha. www.linux-ha.org), fyi

is it possible to fake live IPs. ( AFAIK you can only spoof loopback IP. ) 
because i was wondering they already put into place allowed hosts on 
sshd_config... is it possible to bypass it by some remote host saying that he 
is one of the IP listed in the conf...?


TIA

if you can see its pid then look for it in /proc

/proc/<PID>/

check cmdline or exe to see what exeactly he's running

you can find out a lot of things there

i was looking for our bandwidth eater.... and i did some minor
investigation i  found out that in one of my box someone is doing an ftp
to
ftp.geocities.com.. initial action was to look who's connected and after
did  a pstree to look where the sftp respawn... luckily it didnt respawn
in a user  login... it respawn from init...

can someone tell me where to look so it doesnt happen again....
furthermore  when i did the top:

#top
 PID USER   PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
14791 userx  19      0   229M 229M  588        R        99.9   22.9
23425m  sftp

# pstree -ap

init,1)

  |-sftp,14791) ftp.geocities.com

TIA
          
Hi daddy,

I don't think that was ftp, it's a secure ftp, maybe the box was
compromized doing some upload of your confidential files (passwd/shadow)
putting it to their free webhosting like geocities.  check also your
contabs for other scripts that may run even this was removed in your init
scripts.
