[SOLVED] how can i check if i have openssh running

[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

[CrucifiedEgo]

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

You have a sh*t load of dependencies, really bizarre dependencies for a Ubuntu Server... What kind of Ubuntu Server install did you do? Have you installed anything else after the original isntall? Did you try to install the Desktop?

[Fertech]

no just update, and some basic programs nothing specail
