Buildroot-ts setup ssh
From embeddedTS Manuals
The default configuration has Dropbear set up. Dropbear is a lightweight SSH server.
Make sure the device is configured on the network and set a password for the remote user. SSH will not allow remote connections without a password set. The default configuration does not set a password for the root user, nor are any other users configured.
passwd root
After this setup it is now possible to connect from a remote PC supporting SSH. On Linux/OS X this is the ssh command, or from Windows using a client such as PuTTY.
