Hello,

My TIS firewall recorded these strange messages several times in a day.
But disappeared on the following day and did not appear again.

Can anyone explain to me what these lines are all about ?

Nov 7 11:01:25 MYserver vmunix: securityalert: tcp from 127.0.0.1:2807
to 127.0.0.1 on unserved port 2121 
Nov 7 11:02:01 MYserver vmunix: securityalert: tcp from 127.0.0.1:2814
to 127.0.0.1 on unserved port 2121 
Nov 7 11:02:38 MYserver vmunix: securityalert: tcp from 127.0.0.1:2818
to 127.0.0.1 on unserved port 2121 
Nov 7 11:03:49 MYserver vmunix: securityalert: tcp from 127.0.0.1:2825
to 127.0.0.1 on unserved port 2121 
Nov 7 11:03:49 MYserver vmunix: securityalert: tcp from 127.0.0.1:2826
to 127.0.0.1 on unserved port 2121

Thanks in advance..

Regards,
