Yes. I think so.
Lemme give you some more details.
the perl program basically revolves around this:
@lines=`/usr/utils/prog -v`;
while ($line = shift(@lines)) {
if ($opt_v) {print ("Received : $line\n");}
print $line;
}
prog -v spews out the version
This all works if I run my perl program as root.
should I change prog to suid root?
Why am I getting?:
su-2.05$ /usr/optec/bwutil.pl
Can't do setuid
Any ideas? And what should I do to set it as suid.
chmod 4755 prog
chown root.wheel prog
????
Thanks.
