It is very sad to see this Didier, as we need all the active systems we
can get.
However, I note your list looks like:
Unknown 0 192.168.1.15 2053 65.55.251.22 25 TIME_WAIT
Unknown 0 192.168.1.15 2044 193.17.41.44 25 TIME_WAIT
Unknown 0 192.168.1.15 2028 63.193.154.130 25 TIME_WAIT
Unknown 0 192.168.1.15 2959 65.55.251.22 25 TIME_WAIT
Unknown 0 192.168.1.15 2950 222.231.35.24 25 TIME_WAIT
Unknown 0 192.168.1.15 2947 62.209.45.169 25 TIME_WAIT
Unknown 0 192.168.1.15 2938 213.199.154.22 25 TIME_WAIT
(etc)
Since all of these are to port 25, and you dont list SMTP as a service
you provide, why not just firewall or tune off your mail service? The
problem will then go away.
Even if you do need to run mail, it may be possible to configure it with a
maximum number of permitted connections, implement grey listing etc. All these
can counter the problem.
I suspect that some spammer is trying to use your system as a relay, rather
than a true Denial of Service attack.
Dont let the bad guys win!
