[newbie] How do I turn in a hacker?

[Eric L. Damron]

My secure log showed the following entries:

Oct  6 16:45:12 C287853-A ipop3d[11229]: connect from 193.137.8.223
Oct  6 16:45:12 C287853-A ipop3d[11229]: error: cannot execute
/usr/sbin/ipop3d: No such file or directory

nslookup 193.137.8.223
Name:    oboe.dsi.uminho.pt
Address:  193.137.8.223

He's running an apache webserver and his name is Jorge Figueiredo .

Even with all of this information I'm not sure how to contact his ISP.

Any suggestions?

Thanks
