I have noticed quite a few of these in my logfiles:-

current:Aug 20 06:30:54 [sshd] Failed password for illegal user test from
222.99.91.173 port 47112 ssh2
current:Aug 20 06:30:57 [sshd] Failed password for illegal user guest from
222.99.91.173 port 47189 ssh2
current:Aug 20 06:31:00 [sshd] Failed password for illegal user admin from
222.99.91.173 port 47263 ssh2
current:Aug 20 06:31:02 [sshd] Failed password for illegal user admin from
222.99.91.173 port 47334 ssh2
current:Aug 20 06:31:05 [sshd] Failed password for illegal user user from
222.99.91.173 port 47406 ssh2
current:Aug 20 06:31:08 [sshd] Failed password for root from 222.99.91.173
port 47473 ssh2
current:Aug 20 06:31:10 [sshd] Failed password for root from 222.99.91.173
port 47549 ssh2
current:Aug 20 06:31:13 [sshd] Failed password for root from 222.99.91.173
port 47625 ssh2

Can someone explain the significance of the port numbers?  I have port 22
open for ssh plus 25 and a couple for vnc, but everything else is blocked
at the firewall and yet my server seems to be rejecting login attempts on
other ports because of incorrect usernames and passwords.
