Re: Strange permissions problems running bash scripts from ssh


If I ssh into the same cygwin account from a remote machine, and perform
the identical test, that is, changing directory to a directory in F:,
then run echo test >zap fails with permission denied. 
I am sure is some weird problem with NT permissions or the account under
which the sshd is run, but I have not been able to figure it out.? BTW,
sshd was started from my cygwin account, not Administrator.? Can that be
the problem??? Setting CYGWIN to nontsec or ntsec does not seem to make
a difference.??

A review of <http://cygwin.com/problems.html> might help to get the basics covered.
Another annoyance is that when the bash scripts are run locally, e.g. in
a cygwin window started on the server, everthing works fine.?? Under
SSH, I get minor failures because I start getting DOS line endings in
surprising places.? E.g. commands like basename and the result in a \r.

>And you're sure that 'basename' is Cygwin's version?

>>Yes
