How to configure ssh access to the Zentyal 7.0

[seidhe]

Hello everyone,
I'm a new user in this community.
I had Zentyal 3.2 server but It has failed. Decide to buy the new staff.
On the new machine I installed Zentyal 7.0 and I can not configure the ssh connection...  The ssh configuration folder has additional subfolders and I don't know for what... How to use it?
Can somebody help me properly configure service sshd?
Definitely, I will be grateful for any help.
Best Regards,
Seidhe.

Hi,

You need to check if the ssh service is running, which port it is using and if it is listening in that port:

Code: [Select]

## To see if the SSH is running
sudo systemctl status ssh

## To get the SSH port
sudo grep 'Port' /etc/ssh/sshd_config

## To see if the port is correctly listening (in this example, the port is 22)
ss -tunpl | grep '22'

Once you have ensure that the service is OK, make sure that the firewall allows the connection. You can check it in Zentyal Admin Interface.

Hi,
after modification of ssd_config I received this:

sudo systemctl status ssh

After that I allowed access from external network for ssh in firewall module and I saved settings.
allow    10.8.0.6/32    SSH    access SSH    
allow    10.8.0.0/24    SSH    access SSH
It seams to not working when I tried to connect from external network. Server is running on eth0 192.168.1.2/24. Routing on router is fine.

According the output, your SSH service is using port 100. Did you modify the SSH service (Network -> Services) or created a new one with that particular port?

Yes, I did, I don't want to share the connection on the standard port.

I found the issue, I created a new service for SSH with port 100, but I should add just a new configuration line in the defined SSH service. Now it works. Thanks a lot.
