Hi Everyone!
I am trying to figure out a very odd issue. I am trying to run a perl script remotely over an ssh session on a Solaris box (SunOS peso 5.9 Generic_122300-09 sun4u sparc SUNW,Sun-Fire-880) with perl (v5.6.1 built for sun4-solaris-64int). The process is that the monitoring box (Zenoss) logs in to the target solaris host over ssh with /bin/sh as it's default shell. Then it runs the perl script.
When I walk through this process, I log into the monitoring box and then su to the monitoring process user. Then I make the ssh connection to the target solaris host as the monitoring user. I then run the command to the perl script and I get an output as expected. However, when I run it from the application I get a command not found error. I thought that perhaps when the monitoring app starts its session that it maybe trying to run the script prefaced with another shell like:
/bin/sh /usr/local/zenoss/libexec/check_pp1.pl -r "All paths alive"
When I try to run it that way I get the following error:
$ /bin/sh /usr/local/zenoss/libexec/check_pp1.pl -r "All paths alive"
/usr/local/zenoss/libexec/check_pp1.pl: my: not found
/usr/local/zenoss/libexec/check_pp1.pl: syntax error at line 5: `\./' unexpected
I understand that the 'my' statement is a native function and it does work if I just run the command without the extra shell preface:
$ /usr/local/zenoss/libexec/check_pp1.pl -r "All paths alive"
peso PowerPath 2 Dead Paths Detected
The script looks like this:
Code:
#!/usr/bin/perl
my $hostname = `/bin/hostname`;
if ( $hostname =~ /^(.+?)\./ ) {
$hostname = $1;
}
chomp $hostname;
if ( &check() ) {
print "$hostname\tPowerPath\t0\tAll Paths Alive\n";
} else {
print "$hostname\tPowerPath\t2\tDead Paths Detected\n";
}
sub check {
my ( $status );
$status = 1;
open (IN, "/etc/powermt display dev=all |");
while (<IN>) {
$status = 0 if ( /dead/ );
}
close IN;
return $status;
}
So the question is why the command fails when run under a sub-shell...
Anyone?
Thanks in advance.
