System call scp error 256

[srchulo]

Hi all,

I am running an scp command in my script to copy a file to a remote server. However, whenever I run it from a Perl script, I get a value of 256 returned and it does not work. Yet when I run the exact same command on the command line, I get a value of 0 returned and it works properly.

Does anyone have any idea what the issue could be? Here is the code that I am running:

my $result = `/usr/bin/perl /path/to/script/remote_copy.pl file=1323036682.png remotehost=otherserver localpath=/tmp/ remotepath=/path/to/images`;

remote_copy.pl is a script that just runs scp. Like I said, this exact command runs on command line, just does not work in Perl. I am working in a mod_perl environment if that helps at all.

Many thanks

srchulo:

Usually the web server account has fewer permissions than a user account. Try running the script in a command line shell as the web server account to see what error message shows up. (Or just check the web logs.) Check directory permissions, environment variables, etc.

Thanks roboticus! It was a permissions error.

Does SCP return code 256 apply? If not, we'll likely need to see a listing of /path/to/script/remote_copy.pl.
