Re: path problems when logged in through ssh

I had a similar problem with ssh.  In my case, I couldn't even log in
through ssh because the spawned child process could not find the cygwin
DLL.  The problem was that my system PATH value was longer than 512

The sshd daemon is supposed to copy its environment for the child
process.  Through debugging, I determined the child process did get a
copy of the daemon's environment -- except for PATH, which was set to
some useless default like /usr/sbin:/c/WINNT that didn't include the
cygwin directory.

I looked at the sshd sources and noticed a limit on the environment
value sizes of 512 in the code that copies the environment.  Since
shortening my system PATH value was not an option, I solved the problem
by overriding the PATH value for the sshd daemon's environment.  I did
this by editing the registry for my sshd service, but you can also do it
by recreating the sshd service with cygrunsrv and specifying the PATH
value as part of the service's environment.
