Hi,
I was trying to embed a ssh key in a script and pass it via stdin
(unfortunately not directly supported by ssh). Investigating ways how
this can be done, I ran into a curiosity. With bash, the following does
about what I need:
#!/bin/bash
ssh -i /dev/stdin luser@localhost ls <<EOF
-----BEGIN RSA PRIVATE KEY-----
....
Trying to do the same thing with perl:
#!/usr/bin/perl
open STDIN, ">&DATA";
exec "ssh -i /dev/stdin luser\@localhost ls";
__END__
-----BEGIN RSA PRIVATE KEY-----
....
does _not_ work - ssh will complain "Permissions 0755 for '/dev/stdin'
are too open" (which is not true anyway) and refuse to use the key.
Does somebody have a good explanation for this different behavior?
I thought, from the perspective of ssh both variants should be
equivalent ...
Regards,
Peter
