[Fertech]

im trying to use winscp but says cant connect to the network, i try putty same error. i was looking around the forums and seen i someone had the same problem. then i guess i found out that he needed to install openssh. well me i already have it install, but dont know if its running, how can i check if its running.

The ssh daemon is called 'sshd'. To see if it is running, open a terminal and type 'ps -A | grep sshd'. This will list all processes that have sshd in their names. If you see one, then the daemon is running; otherwise it is not.

Use this command:

ps aux | grep ssh


My results:

jordan@einstein:~$ ps aux | grep ssh
root      5301  0.0  0.0   5280   988 ?        Ss   Oct20   0:00 /usr/sbin/sshd
jordan    6734  0.0  0.0   4432   540 ?        Ss   Oct20   0:04 /usr/bin/ssh-agent x-session-manager
jordan   27014  0.0  0.0   2980   776 pts/0    S+   12:21   0:00 grep ssh

sshd is the server

In the true spirit of unix, there's more than one way to do anything. I'd recommend doing something like:

sudo netstat -natp | grep sshd

This should show you if sshd is running, and if it is, what ip address and port it's listening on. It outputs something like this:

james@poseidon [~] $ sudo netstat -natp | grep ssh
tcp        0      0 67.207.149.257:30000     0.0.0.0:*    LISTEN 3647/sshd

In this case, it's listening on 67.207.149.257(this is fake for obvious reasons), port 30000.

I always use telnet to test low level stuff:
$ telnet servernameoripaddress portnumber

Ferinstance:
$ telnet mylab 22
Trying 172.24.107.10...
Connected to mylab.example.com.
Escape character is '^]'.
SSH-2.0-OpenSSH_4.7

Now I know the DNS resolves, the server is listening and the firewall allows the port through.

Cheers,

Herman

Yours isn't running.

Start it with sudo /etc/init.d/ssh start

Did you installed it?

sudo aptitude install openssh-server (ENTER)
