[cobalt-users] Constant problem with one IP 'attacking' me.

["First Hosting" <sales@xxxxxxxxxxxxxxxxxx>]

Hi,

For some time now, I have had the following message reported by Logcheck
on an hourly basis. I have contacted my hosts, who own the IP concerned,
but they say the enquiry is not coming from them.

The message that logcheck gives me every hour is:-

Jan 24 13:00:07 cob698 portsentry[1427]: attackalert: UDP scan from
host: 209.207.168.221/209.207.168.221 to UDP port: 820 
Jan 24 13:00:07 cob698 portsentry[1427]: attackalert: Host:
209.207.168.221/209.207.168.221 is already blocked Ignoring 
Jan 24 13:04:08 cob698 portsentry[1427]: attackalert: UDP scan from
host: 209.207.168.221/209.207.168.221 to UDP port: 820 
Jan 24 13:04:08 cob698 portsentry[1427]: attackalert: Host:
209.207.168.221/209.207.168.221 is already blocked Ignoring 

Etc...

I have tried and failed to get rid of these messages - can anyone
suggest what I can do to stop the messages from coming through, or
better still to stop the 'attacks' in the first place.

Thanks in advance,

Ian.
