SSH

Not exactly sure if this does work, but seems like it should.

nvram_get SSH_SERVER_REMOTE_ENABLE

Default status

Enable 

nvram_set SSH_SERVER_REMOTE_ENABLE 1

After running above command

Commit changes

nvram_get commit

Reboot

reboot

Change password

Seems like I am missing a step. Seems to change the password in the nvram, but does not actually change it permanently

Get current password

nvram_get 2860 Password
admin

Set Password

nvram_set Password newpassword

Commit Changes and reboot

nvram_set commit
reboot

Uses some of the commands (i.e. nvram_get 2860 HostName )
