BUSYBOX - SSHing to a W-Gate Router

I had to ssh ing to this box running a a stripped version of BusyBox witha really tiny ssh server support with Dropbear that wasn't accepting connection from a regular ssh client on Ubuntu.
After succesfully trying connecting with the dbclient (the dropbear client that acts more or less as a ssh client) , dbclient that is available in ubuntu official software I have noticed that thas box need a specific kind of MAC (Message Authentication Code) algorithm to connect.



Using this option ( -o MACs=hmac-sha1 ) the ssh client connected succesfully letting me make the tunnel that I wanted:


ssh -o MACs=hmac-sha1 -vvvl user ip
