I'm a novice at network things. I enabled remote-login on my home mac (OS 10.12.5) so I could git between home and office. To make it work, I had to tell the wifi to fix my Mac's IP and to redirect Port 22 to it. Works fine. My log file, however, has thousands of messages (one every few seconds) of the form:
com.apple.xpc.launchd (com.openssh.sshd._hex_[_int_]): Service exited with abnormal code: 255
Nothing in the log explicitly mentions a refused authentication, and I don't seem to have an
secure.log file (other posts suggested to look in there).
Any idea what's going on here?
