Hi Everyone, I have been using RH Linux on our network for over 7 years
now and we have been testing out Fedora Core 1 on a machine and have been
pleased so far. However we have run
into a problem that I think is related to Fedora since we never have had the problem
in the Red Hat distros. The problem we are having is with Perl 5.8.1. For
the most part Perl works fine but a lot of our
programs in perl use the command “exec”
in the script. For example here is
a line of code from a program called usersearch.pl: if ($status == 1) { } else { exec “namelookup.pl” } I don’t want to get into programming here because this
isn’t what this list is for. However the problem is that Fedora does
not execute the “exec namelookup.pl” command. If you run the program from the command
line you get nothing like shown below (the status is equal to 0 for programmers
out there): [dave@doc dave]# ./usersearch.pl [dave@doc dave]# However, in all other RH distros the
program would execute the namelookup.pl program and you would get this output: [dave@doc dave]# ./usersearch.pl Enter ID of person: It appears that Fedora is somehow preventing Perl from running the “exec” command. I say “appears” because I
also believe it could be a problem with the Perl
packages in Fedora but I have the same versions (Perl
5.8.1) on RH9 and Fedora Core 1. It
works on RH9 but not Fedora. I have
been reading about a new feature in Fedora called “exec-shield”
which looks like it helps prevent programs from running in ceratin
memory areas. Could this be the
source of the problem. Has anyone else noticed anything weird
with Perl in Fedora? Like I said, not sure if it’s totally a Fedora problem
or Perl problem but I wanted to start where the only
thing I changed was the OS. Any
help someone could give would be appreciated. Thanks, Dave |
