[SOLVED] sshd not starting after upgrade

[DePingus]

Let's get the shameful part out of the way first...So I foolishly did a pacman -Syyu and rebooted without reading and now my sshd doesn't start. I can tell only because nmap from a remote system shows the only open ports to be samba; 139 and 445.

I am able to connect the USB flash drive to a different system and look through the logs. I couldn't find anything of relevance in anything but the pacman.log. Here is the pacman.log:

I assume the important part is where sshd was moved to /usr/bin. But I could be wrong. Perhaps my system upgraded itself to systemd and failed to systemctl enable sshd? Or even a combination of the two? Can I symlink or copy sshd from its new location in /usr/bin to its old home? And where would that even be?

Of course, this is a completely headless server and I only have access to the file system by hooking its USB flash drive to a different system. Any ideas what went wrong? How can I start sshd up again by just accessing files (no access to the systemctl command)?

The rc.d scripts for openssh, along with most of the other packages, have been removed or are in the process of being removed. If you're not on systemd, get on systemd.

[moonman]

1. complete reinstall
2. chroot from another arm system
3. chroot from x86 system with qemu-user (may be difficult)

You can try putting this under /etc/rc.d under sshd name and make it executable

There could be a problem?
