Me and my colleague spent a day or two trying to fix issues like this that kept creeping up on our beaglebone black boards. We would be unable to SSH to them or it would hang at: debug1: identity file /Users/cmicali/.ssh/id_dsa-cert type -1 It wouldn't always say connection closed. I tried every single idea I saw posted in this thread and others.
In the end it seemed Avahi daemon was causing issues. I found this through the following: 1.) I ran "top" which showed me that systemd and systemd-journal were running at 100% of the CPU combined. 2.) I used "journalctl -b" to see what journal output was being created for this boot. This showed error after error for Avahi at full CPU speed. 3.) I stopped avahi-daemon, which I haven't yet seen the ramifications of using: systemctl disable avahi-daemon.service 4.) I ran "df -h" which showed me that my storage was completely used up! 5.) I located the log in /var/log/journal/<some weird string of numbers and letters> 6.) I deleted all the files in the aforementioned directory 7.) I did as this thread suggests for the 20th time and deleted the dropbear_rsa_host_key file 8.) I stopped dropbear using: "/etc/init.d/dropbear stop" 9.) I started dropbear using "/etc/init.d/dropbear start" 10.) It proceeded to generate a new key. 11.) At this point I tried connecting again from a client which was successful. Perhaps I could have stopped at step 6 and just stopped and restarted dropbear but that's what I did to make it work! Hope this saves someone else a day -.- On Wednesday, May 1, 2013 2:39:49 PM UTC-7, cmicali wrote: > > Hi, > > I got two BBBs in the mail - I plugged one in and everything has been > working fine.
