I`ve tried to install ssh ssh-server and ssh-client in linux on dex , but there seems something wrong with the ssh when i tried to connect to dex on linux in my computer .
get the ip address in terminal using ifconfig

then i tried :

    dextop@localhost:~$ ps |grep ssh
    dextop@localhost:~$ sudo /etc/init.d/ssh start
    [sudo] password for dextop:
    * Starting OpenBSD Secure Shell server sshd [ OK ]
    dextop@localhost:~$ ps |grep ssh
    dextop@localhost:~$

it seem`s ssh was not running.

Is that we can`t enable the port22 due to the Android limit ?
Is there any way to connect to linux on dex by ssh?

If ssh works well in linux on dex , that may help develop a lot!

Port 22 can’t be used in android
Linux on Dex is executing a container version of Ubuntu. The container cannot open privileged ports which is any port lower than 1000.
