Hi,

I am trying to connect to another m/c in my network with ssh
when i execute the command as
# ssh 10.10.10.69

it gives me following error as
ssh: connect to host 10.10.10.69 port 22: Connection refused

i can't understand why it is happening?
i checkd the following files on 10.10.10.69 it's contents are
vi /etc/sysconfig/system-config-firewall

--enabled
--port=22:tcp

what should i do???

Is the sshd running there (to listen for incoming connections)?

You should be able to quickly check using netstat if sshd is running. do this from the box you are trying to connect to..

Code:

it-etch:~# netstat -alnp | grep ::22

tcp6       0      0 :::22                   :::*                    LISTEN      3205/sshd

Do you try to connect localhost with ssh ?

[root@CentOS ssh]# ssh cf.linux@localhost
cf.linux@localhost's password:

Do you check the configuration of ssh in /etc/ssh/sshd_config;

Quote:

Port 22
#Protocol 2,1
Protocol 2
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::
…………

There maybe some errors in your firewall settings ,the result can not be accessed.

Code:

when i execute the command as
# ssh 10.10.10.69

The root user isn't normally allowed to login with ssh
So ssh to the other computer as yourself, and then become root in the normal manner if you need to:

Code:

user@localhost:~$ ssh 10.10.10.69
user@10.10.10.69:~$ su root
root@10.10.10.69:~#

Sounds like you don't have SSHD or openssh-server installed correctly, what distro are you using? if your using debian for example, that will likely not come with openssh-server straight after an install and you may need to use apt-get to install it.
