Re: How to debug inetd/sshd services?

[Peter Buckley <peter dot buckley at cportcorp dot com>]

I think it is the right idea to change the AppArgs 
to have the "-d" (debug) option. IIRC you should be able to 
do this for both inetd and sshd, but it may be easier to 
install the service with something like Firedaemon so you 
can access the parameters from the services control pane. 

The error you are getting when sshd service fails to start 
sounds like your user account doesn't have the necessary 
rights to start a service. You may want to give your account 
those rights- they are detailed in 

/usr/doc/cygwin/inetutils-1.3.2.README 

Or you can try starting the service from the services control panel, 
or rebooting to start automatically. 

HTH,

Your mouse has moved.
