I've just had an email from my hosting company telling me I'm in violation of their Acceptable Use Policy.
They forwarded me an email from another company complaining about something to do with a "TCP sweep of port 22". They included a snippet from their logs,
20:29:43 <MY_SERVER_IP> 0.0.0.0 [TCP-SWEEP] (total=325,dp=22,min=22.214.171.124,max=126.96.36.199,Mar21-20:26:34,Mar21-20:26:34) (USI-amsxaid01)
Now, my server knowledge is limited at best, and I've absolutely no idea what this is or what could be causing it.
Any help would be greatly appreciated!
