Putty connecting Ubuntu:network Error:connection refused

Reason:

Ubuntu has a bug: missing a folder in the/var/run/directory sshd

Workaround:

At the command line, enter:

sudo mkdir/var/run/sshd

Sudo/usr/sbin/sshd

Netstat-nlt

The following log issues are resolved:

Active Internet connections (only servers)
Proto recv-q send-q Local address Foreign address state
TCP 0 0 127.0.1.1:53 0.0.0.0:* LISTEN
TCP 0 0 0.0.0.0:22 0.0.0.0:* LISTEN

TCP6 0 0::: $:::* LISTEN
TCP6 0 0:: 1:631:::* LISTEN

You can see that port 22nd is open and you can use Putty to connect to Linux for remote access.
