Our servers usually behave nicely, but these are some tools to use to make sure we know if they aren't.

Issues connecting via ssh to VPS

Recently, after an update of an Ubuntu 16.04 LTS VPS, we got the following connection issue:

$ nc -zvn IPADDRESS PORT

nc: connectx to IPADDRESS port PORT (tcp) failed: Connection refused

The following command yields more information:

sshd -t

"Missing priviledge separation directory: /var/run/sshd"

The fix in this case was easy enough:

mkdir /var/run/sshd

sshd -t

(no issues reported)

service sshd restart

all good!
