SSH server on Legato

Hi all,
We are planning to connect WP7605 and our SoC using USB, and we would like to use SSH to control WP7605 from our SoC.
I think this structure is the same as MangOH board and ubuntu PC.
I guess some kind of SSH server is running on Legato in WP7605.
I’d appreciate any advice regarding the name of this SSH server like module and where I can find the code of it.

it used this one:

root@swi-mdm9x28-wp:~# ps aux | grep dropbear
root 1343 0.0 0.2 2396 336 ? Ss Oct25 0:00 /usr/sbin/dropbear -r /etc/dropbear/dropbear_rsa_host_key -p 22 -B

Thank you for the information.
I’ve found the code at GitHUB.
