I was upgrading FreeBSD on my virtual host, from 10.0 to 11.1. While upgrading from 11.0 to 11.1 I was confronted with a large amount of files that had to be diffed and edited. I tried my best, failed, and now can't login to my server.

Using ssh -vvv I can see the following happening:

OpenSSH_7.3p1, OpenSSL 1.0.2l  25 May 2017

debug2: resolving "xxxx" port 22

debug1: Enabling compatibility mode for protocol 2.0

Is there a way to just force FreeBSD to accept whatever factory settings it comes with on 11.1? Basically wipe everything out and let me reconfigure from the start?

Update

My host comes with 10.0 only so a new clean install would involve me upgrading from 10.0 to 11.1 all over again. I'm already at 11.1, I just want it to work.

  • But I don't know what else is broken. And the file doesn't exist. – ruipacheco Oct 08 '17 at 11:50
  • some info here https://unix.stackexchange.com/a/321972/153195 see the similar problems – GAD3R Oct 08 '17 at 12:07
  • During the upgrade on the server freebsd-update alters /etc/ssh/sshd_config on your FreeBSD server. It tries to be smart about it but it has messed up my config more than once. It is a simple text file which is easy to read and correct. – Claus Andersen Oct 09 '17 at 08:15
  • Do you have physical access to host, if so replace /etc/ssh/sshd_config on the disk with a version from a FreeBSD 11.1 installation. That should let you back in - but who knows what else is broken if you did not complete the merge fully. – ColtonCat Mar 20 '18 at 04:16
