Found this on the net:
It's because :: is IPv6 address, and this is what SSH binds to when it
first start's, being that IPv4 is also enabled, when it tries to bind to
the IPv4 address, it find's that it is already being used.
Possibly disable IPv6 support in kernel (?) or use the ListenAddress
option in your SSHD server config file.
If you're not using IPv6, just disable it in sshd_config:
ListenAddress 0.0.0.0
#ListenAddress ::
(or bind the ListenAddress to a specific IP)

Something happened after the last openssh update. Now every time
ssh is (re)started, I get this message in my syslog:
Nov 14 08:16:57 lansky sshd[1760]: Server listening on :: port 22.
Nov 14 08:16:57 lansky sshd[1760]: error: Bind to port 22 on 0.0.0.0
failed: Address already in use.
That was after a server restart this morning (to boot up the new
2239 kernel). The thing is, it does start up, it does run. And I can
shut it down completely (service sshd stop) and I can verify that no
ssh process is running and that there's nothing listening on port 22
('nmap -sS localhost' and by actually trying to connect to port 22
with another machine). Yet when I tell it to start ssh again, it
starts, but not after complaining with the above message.
Soooo, inquiring minds want to know.
