Hi all,

I tried to ssh to my cygwin box today and was unable to connect. It
seems the sshd service can no longer run, for reasons that mystify me:
# net start sshd
System error 1069 has occurred.

The service did not start due to a logon failure.

I wasn't aware of having changed anything; would it be advisable to just
reinstall sshd from setup.exe and/or sshd_host_config, or is there some
simple troubleshooting I might do?

reinstall is not the way. Likely something reset the cyg_server privileges. Try to re-enable them with

editrights -u cyg_server -a SeAssignPrimaryTokenPrivilege
editrights -u cyg_server -a SeCreateTokenPrivilege
editrights -u cyg_server -a SeTcbPrivilege
editrights -u cyg_server -a SeServiceLogonRight
editrights -u cyg_server -a SeIncreaseQuotaPrivilege
No luck, the same error still occurs. However, now that you mention it, I
did play with cygserver settings while trying to install pgsql a while back.


Is there a way to view the privileges to see what I may have broken?

$ editrights -u cyg_server -l SeAssignPrimaryTokenPrivilege SeCreateTokenPrivilege SeTcbPrivilege SeServiceLogonRight SeDenyRemoteInteractiveLogonRight
Mine has all those, plus SeIncreaseQuotaPrivilege (possibly thanks to the above from Marco).

It seems that I managed to de-configure sshd somehow. There's no sshd_config in /etc/ (just the skeleton in /etc/defaults/), and sshd-host-config doesn't seem to exist, either. So, I blew away the sshd and cygrunsrv services and their associated users and re-ran ssh-host-config. All is well now... except that now an enormous ascii art hippo greets me at login. Ick.

Thanks,
Ryan
