RE: [Ssh-sftp-perl-users] Running a Net::SSH::Perl script via a W eb server

[Ari G. <ar...@su...>]

Big thanks to Vladimir for this one, it sure is less then the few lines of
code I wrote to do the same thing.

Just as an update to this, it's starting to look like this may really be a
systems issue (at least on my side) and not really the Net::SSH:Perl module.

The process which calls the script for me is owned by one user, but that
process is a child process of one that is owned by root.  So what it looks
like is that even though the UID is that of one user, the shell is that of
root's.  Similar to the difference between doing an: 
	su - username     (where you inherit username's shell)   versus
	su username		(where you don't inherit....)

And so that's seems to be why we need to reset the HOME env var, so that the
proper known_hosts file is accessed.

Regards,
Ari

I am too lazy to research why....
Quick solution is:

$ENV{HOME}=(getpwuid $<)[7];
