Post scans

I don't mind the random port scan, but I start to become a tad suspicious of port scans over a period of 3 days from the  same plusnet IP.

Re: Post scans

It's one of the servers that we use for the Community Site - I can't see it being anything to worry about.

Re: Post scans

Thanks Chris,
I'm not worried, just puzzled.
Why has a plusnet "community server" taken such an interest in my ports.  Cheesy

I don't know why you've only recently started noticing it. The suprious packets arrive during or shortly after you browse these forums. The source port would be 44340 if you use https, otherwise the source port is 80.
