I'm using OpenWRT. My router, whose IP address changes unpredictably, makes its ssh-listening port available on another host running at a stable IP address, using autossh/dropbear to create a reverse channel.
Sometimes the host's key changes from time to time, which can stop the autossh process at a prompt (to nobody) to decide what to do about the change. Ordinary OpenSSH has a StrictHostKeyChecking option which can be used to bypass the so-called "ask" prompt and just make the connection regardless. By reading the source, I learned that Dropbear's ssh client evidently has a similar feature, the "-y" invocation option. But I can't pass the -y to it via autossh because autossh doesn't approve of it. Dropbear's ssh client also does not offer a config file utility, AFAIK. Dropbear evidently ignores all -o options, too; they wind up in a bit bucket called something like "dummy". Does anybody know the answer, short of editing/recompiling autossh so it won't be so persnickety and just get out of the way? Steve Newcomb
