My experience with Linux is limited and as part of a project, I ordered a Linux dedicated server. This is an unmanaged server with OpenSuSE 13.2. When I try to ssh into the server, I get a connection refused message
ssh: connect to host xxx.xxx... port 22: Connection refused
I think their default image does not comes with ssh enabled on startup but I may be wrong. They provide a rescue system which is a Linux system installed and loaded from ram for troubleshooting. When I load this, I can connect to the system via SSH. I can mount the hdd and make changes.
I'd like to know how to check and/or whatever configuration changes that need to be done to enable ssh on startup for OpenSuSE 13.2 from within a recovery system. I can provide any configuration file contents if required. I'm basically from a Windows background and hence if you can provide verbose steps, it will be helpful.
As part of my research, I checked init.d file, there was no sshd
file in there, ssh is installed I guess as there exists files in /etc/ssh
like `/etc/ssh/sshd_config.

1. Verify installation
Run
which sshd
to get the path it is called from. If you don't get/usr/sbin/sshd
in response, it is most likely not installed.2. Installing sshd
Run
zypper in openssh
to install the application.3. Check firewall
Run the command
cat /etc/sysconfig/SuSEfirewall2 | grep sshd
.You need to see
FW_CONFIGURATIONS_EXT="sshd"
- This means the firewall allows incoming traffic on port 22.If you do not find it, you may add it using a text editor like this:
vi /etc/sysconfig/SuSEfirewall2
and locate the line where it saysFW_CONFIGURATIONS_EXT=""
and change it toFW_CONFIGURATIONS_EXT="sshd"
4. Check the service is running
systemctl status sshd | grep Active
- If you getActive: inactive (dead)
you need to start it withsystemctl start sshd
.Run the command again
systemctl status sshd | grep Active
and you should now seeActive: active (running) since ...
5. Enable SSH on startup
systemctl enable sshd
