- Subject: Upgrade Challenges, ssh login failure after update
I just updated Cygwin to the latest version from one that had been
installed in maybe 2009... old.
During the update process there was a note to go to cygwin.com to see
what had changed in the new version that might affect me, but in the
"upgrade" or the "faq" area I could find nothing warning me about
I was installing this on a box 2000 miles away where I tunnel remote
desktop through ssh. Thank goodness I took down the firewall before I
rebooted, because ssh no longer worked after a reboot, and I had to make
a direct remote desktop connection to the machine before I got ssh up
I'm sending this mail to warn other users trying to upgrade sshd...
After the upgrade I got login failures even though sshd service was
running. I Googled and Googled, but I couldn't find an answer; port was
open, ssh was up, and ssh connections worked fine (even to the external
IP) from the local cygwin ssh, but not from a remote ssh. Logging
locally didn't help, ssh -vvv remotely didn't help. FINALLY I figured it
out, it was that the USERNAMEs are now case sensitive!!! So
"administrator" fails but "Administrator" succeeds. I read somewhere I
can fix this now by going back and editing /etc/passwd, but I haven't
tried that yet; right now I'm just happy to have my firewall back up and
tunneling remote desktop through ssh again. (I did a ssh-host-config in
the process of debugging but I don't think I needed to.)
Since I couldn't find this answer I'm sending it now to the list,
hopefully the next person that runs into this will find it.
