RE: SV: [cobalt-security] - too many sendmail processes



Something is going on...The list goes on and on I would say there are about 50 sendmail processes. Here is my setup

Maximum Message Size (MB) [5]
Smart Relay Host Name [BLANK]
Relay for the following Hosts/Domains [IPs,Domain names on BOX]
Host/Domain Aliases [all www.domain.com on BOX]
Reject the following Users/Hosts/Domains [Blank]
POP Before SMTP Relaying [ON]
Relay Window (minutes) [15]


When i run ps aux the processes with send mail all look like this.
root 3013 0.0 1.3 2896 1772 ? S 10:22 0:00 sendmail: q2/f8SE

Anymore ideas...

Malcolm- You said I can look in the outgoing mail to see what it is, where is the directory?

type
ps aux
this will show what started the process e.g. script, program, etc
it'll give you an indication of what is using sendmail
I'd also suggest having a look in the outgoing mail to see what it contains


if you don't like it kill it
kill PID#

that'll give you some pointers for more info on howtos just post back

I am fairly new to the security world but i installed chkrootkit on one of
my cobalts and have found it to be a great way to keep on top of the log
files. My problem however is after I installed it I noticed when I ran top
the following was in the list: (not sure if chkrootkit has anything to do
with this)

1911 root     0   0  1660 1660  1388 S       0  0.0  1.2   0:00 sendmail
1912 root     0   0  1768 1768  1336 S       0  0.0  1.3   0:00 sendmail
2000 root     0   0  1660 1660  1384 S       0  0.0  1.2   0:00 sendmail
2001 root     0   0  1820 1820  1344 S       0  0.0  1.4   0:00 sendmail
2108 root     0   0  1660 1660  1388 S       0  0.0  1.2   0:00 sendmail
2111 root     0   0  1768 1768  1336 S       0  0.0  1.3   0:00 sendmail
2174 root     0   0  1660 1660  1388 S       0  0.0  1.2   0:00 sendmail
2175 root     0   0  1776 1776  1340 S       0  0.0  1.3   0:00 sendmail
2224 root     0   0  1660 1660  1384 S       0  0.0  1.2   0:00 sendmail
2225 root     0   0  1820 1820  1344 S       0  0.0  1.4   0:00 sendmail
2246 root     0   0  1660 1660  1388 S       0  0.0  1.2   0:00 sendmail
2248 root     0   0  1776 1776  1340 S       0  0.0  1.3   0:00 sendmail
etc....

Any idea on what is causing this or what is going on? Is there a way to kill
these or is it ok to have them running? I have about 15 sites on this
server.

Hope you guys can help.

Cheers,
Nick Damoulakis
