Re: [cobalt-security] IP listed as restricted doing Whois from samspade.org



Yes I am back with silly IP questions again ;-)

Thanks for the above URL, I ran another IP that FTP'd into my RAQ
(crc.xnet.ro[217.10.198.254]). It reports back with the below, that bad part
is I don't have any customers in Romania, so now I am on the hunt to chase
what they may have done in the 5 mins they were FTP'd in. How do I tell what
user they FTP in with? I know how to ps, ps aux, top, who etc. But I am an
amateur here and need all the help I can get.


Check you /var/log/messages file for a line similar to:

Jun 11 10:33:19 www PAM_pwdb[5946]: (ftp) session opened for user *** by (uid=0)

This line tells you which user logged into FTP and at what time.

I recommend you install Logcheck if you haven't already, which will report this kind of information back to you on an hourly basis. Check out http://www.psionic.com/abacus/logcheck for more information. It is very simple to install, but I would be happy to provide you with instructions in case you get stuck.
