Hello list.
Today I saw something strange in logs one of my servers. Part of the
/var/log/security:
Mar 12 15:01:03 server sshd[28505]: Invalid user abc from ::ffff:x.x.x.x
Mar 12 15:01:03 server sshd[28503]: Invalid user ab from ::ffff:x.x.x.x
Mar 12 15:01:03 server sshd[28507]: Invalid user abcd from ::ffff:x.x.x.x
Mar 12 15:01:03 server sshd[28509]: Invalid user abcde from ::ffff:x.x.x.x
Mar 12 15:01:03 server sshd[28511]: Invalid user abcdef from ::ffff:x.x.x.x
Mar 12 15:01:04 server sshd[28515]: Invalid user abcdefgh from ::ffff:x.x.x.x
Mar 12 15:01:04 server sshd[28513]: Invalid user abcdefg from ::ffff:x.x.x.x
"abcdefgh" is my username to the different machine in the other
domain, x.x.x.x it's my workstation. Yesterday, I loged into machine
where my login is "abcdefgh" from x.x.x.x. But not to the "server".
Anybody has an idea?
Regards
