Try without identifying current user Small change that warns the user if the current user cannot be identified rather than aborting. This came in handy when I put dropbear on a dlink that did not have a true user environment. Falling back on the "-l" option and user@ options works just fine as a client. The only implication I found is that the -J option will fail ungracefully without a known own_user.

#!/bin/sh
exec 2>&1
exec dropbear -d ./dropbear_dss_host_key -r ./dropbear_rsa_host_key -F -E -p 22
