How to enable SSH server?

[jnpine]

Thanks for your replies! 

I have already obtained the PinePhone IP address using ¨ifconfig¨. 

In Mobian is available in /sbin/ifconfig
It has to be executed in the path as it is not aliased. 

I am indeed trying to connect via wifi, I have already accomplish this in Ubuntu touch but not in Mobian. 

I am thinking that I am missing something in the configuration to enable incoming SSH connections onto the PinePhone in Mobian.

Ooh - have you installed pinephone-devtools or just openssh-server? If just openssh then install dnsmasq-base as well.

I installed both packages and was not able to SSH neither, the problem was my client: iTerminal iOS 13.5 in an iPhone.   I changed to another SSH app WebSSH and it is working now.  
I am doing some changes in the /etc/sshd_config to see if something is preventing SSH from the other app. 
So far have deactivated:
#ChallengeResponseAuthentication
#UsePAM yes

And added: 
PermitRootLogin yes. ##To enable SSH from root user, this is working so far. 

I think I will mark this as solved. 
Thanks to everyone for your replies and help!
