I've got a CGI script where I am trying to run a shell command and report the results. For some reason it works as expected from the command line but not via the web server.
#!/usr/bin/perl -w
use Data::Dumper;
use CGI qw/:standard/;
use CGI::Carp 'fatalsToBrowser';
use strict;
$ENV{'PATH'} = '/bin:/usr/bin';
delete @ENV{'IFS', 'CDPATH', 'ENV', 'BASH_ENV'};
my $cmd = qq(rsh case3 /home/dncms/bin/testForwardLookup.pl case3 &|);
my $result = "";
print header;
print "running {$cmd}\n";
open(FOO,$cmd) || die "Failed to run $cmd: $!";
while (<FOO>)
{
print "feh: ";
$result .= "$_\n";
}
close(FOO);
print ( $result );
Here's the shell response:
dncms@alien 531 > perl foo.pl
Content-Type: text/html; charset=ISO-8859-1
running {rsh case3 /home/dncms/bin/testForwardLookup.pl case3 &|}
feh: 130.42.0.117
Here's the sum total of the web response:
running {rsh case3 /home/dncms/bin/testForwardLookup.pl case3 &|}
It doesn't seem to matter whether I use setguid or not. Does anyone have an idea of what I'm doing wrong? Thanks!
