While looking through my logs the other day, I came across the following in
my logs ...
sshd[2115]: Server listening on :: port 22.
sshd[2115]: error: Bind to port 22 on 0.0.0.0 failed: Address already in
use.
I have three questions:
(1) should this concern me? My gut says yes but I don't know why.
(2) why is ssh looking to bind to a port on 0.0.0.0 (why isn't is simply
looking to bind the port on the legal addresses for the machine, ie those
that I see when I do ifconfig -a?)
(3) how do I find what app/server/etc has already done the bind of port 22
to 0.0.0.0?
regards,
ed
