Agreed. "Host key verification failed" tells me that either the permission or the ownership of /etc/key-rsa is wrong-- if you're going to run autossh as a SYSTEM service, then the key has to be owned by SYSTEM and only readable by it. Another possibility is that the key is encrypted, so SYSTEM can't read it without a password; maybe your user process is getting it from an ssh-agent. A good way to get more information about why the service fails to start would be to add -v or -vv to the ssh flags (within the argument of -a). > First thing to try: run the service as your user, i.e. add --user name> to the service installation. Yes, this is really better. I need to recommend this in the autossh README. > And don't expect too much, I use it all the time and it works but it > fails to start very often, I end up starting it manually. Hm, I'm surprised to hear that. I haven't run autossh as a service in a while, but when I did it worked very reliably for me. Can you tell me anything more about how or why it fails to start?
