Greetings,

Exploit scanning (RPC mountd, NFS showmounts, NMAP-based pings, FTP
attempts) was detected from host d48.z194-58-100.relcom.ru of the
EUnet/RELCOM network between 1:45 PM and 2:43 PM EST (GMT-0500) on
August 15 directed at our web server. This type of network activity is
not appreciated, and we would prefer its discontinuance.  Please
forward this notification to the responsible party.

Thank you,
