Hi there,

Are you able to ping 192.168.1.139 IP address?

Is firewall running on 192.168.1.139. Usually if firewall is on it gives connection refused. The error message that you mentioned show that client machine is unable to connect to 192.168.1.139 on port 22.

Which means either ssh service is not running on 192.168.1.139 or your client machine is unable to communicate to 192.168.1.139.

Let us know the linux distribution that you are running on.

The above tells us that the request is getting to the server but it is getting refused. Are you sure firewall is disabled. Did you check the selinux status?

We will not be able to help you if you will not provide us the full information. I asked you which linux distribution you are using but you didnt mention.

Did you uncomment these lines in /etc/ssh/sshd_config file mentioned below :-

#Port 22
#Protocol 2,1

if not, uncomment these above two lines in file /etc/ssh/sshd_config

Thanks colucix

Hi srinivasmmdl,

fedora15 32bit os(fc15-i686)

I would suggest you to check selinux status on this server. You can check the selinux status using the following command:

Code:

sestatus

If it is running in enforcing mode then you can then disable it and then give it a try. To disable selinux edit its config file. Following is the command:

Code:

vi /etc/selinux/config

Change the value of SELINUX=enforcing TO SELINUX=disable, restart you machine and then give it a try to ssh.

I hope this helps.

I noticed you mentioned running an SCP command are you able to just SSH directly into a shell, or are you using scponly or some other type of restrictive shell? Is SCP enabled in your ssh config?
