Running a Net::SFTP::Foreign script from cron

rah has asked for the wisdom of the Perl Monks concerning the following question:

I wrote a script using the Net::SFTP::Foreign module for performing unattended sftp file transfers. The script works beautifully from the command line on any platform. It also performs without problems when called from cron on MacOS X or on Redhat Linux. However when I try to run the same script from cron on HP-UX or AIX, it fails with a broken pipe error. The failure is

open2: exec of ssh -l user some.location.com -s sftp failed at /usr/local/lib/perl5/site_perl/5.8.0/Net/SFTP/Foreign.pm line 67

Additionally, HP-UX complains about write to ssh pipe error, while AIX complains about a read from ssh pipe error. The setup uses an RSA key, so the script does not prompt for any user input. Does anyone know what is going on and/or how I might be able to coax this script to run from cron?

Net::SFTP::Foreign

ssh

Net::SFTP

ssh

Net::SFTP::Foreign

The remedy is either to switch to Net::SFTP or to set ssh_cmd => $sshcmd to the full path of your ssh.

my $sftp = Net::SFTP::Foreign->new('host',{ ssh_cmd => '/usr/bin/ssh' 
+});

Thank you so much. I must have had one of those duh moments. ssh is in /usr/bin on my two systems that work (and therefore in my sparse cron environment), but installed elsewhere on my two systems that failed. Good catch. Works fine now.

ssh_cmd => $sshcmd

perl "D:\Projects\sftp.plx"

$ssh_cmd
