Everyone,

I've actually had to lock down most ports on my server; because, I got
tired of all the attempts at attacks.
Everyone, please use a firewall.  I've noticed many attacks to the
following ports:
   111 -- sunrpc  ** this effects Linux machines
   135 -- DCE Endpoint Resolution
   137 -- netbios-ns
   139 -- netbios-ssn
   445 -- microsoft-ds  ** these affects samba services as well.
 1433 -- ms-sql-s
 1434 -- ms-sql-m    ** I don't know why SQL ports are being attacked.

  1023 -- ???
  5554 -- ???
  9898 -- ???  ** this group may be related to PCAnywhere, or Worm, etc.

The most active:  port 445 by far!

Just giving everyone a heads-up on the security issues.

Good points James...you missed one though... port 22. I see more attempts on SSH than any other port....stupid and LAME attempts but more on this than any other...

-Eucke




Yes, I missed that in the logs. They are so few attempts, I only got 2 during the one day I sampled. Of course, when they can connect, they try several names.

I also left off ports:  55838, 1026, 1027, 4899, 1334, 1025,. 6129...

If anyone is interested, I can send a copy of the report or even the log file information.

Thanks,
James Kosin
