Re: [Jailkit-users] [Fwd: Trouble with perl program on Gentoo Linux]

[Stephen Tallowitz]

Hello John,

I like a challenge and so I've tried getting test.pl to work on my system in a 
jail. I've succeeded and this is how I did it:

jk_init /srv/jailtest/ uidbasic
jk_cp -v /srv/jailtest/ /bin/bash
# create jailuser with login shell /bin/bash, copy test.pl to users' directory 
and change test.pl permissions and mode bits
# then create a perl binary package using quickpkg from gentoolkit (gentoo 
specific) and install that package in the jail directory.
# Users of other distributions may want to consult their distributors' manuals 
to find out how to install a package to a second location in the filetree
quickpkg perl
tar -xvjf /usr/portage/packages/All/perl-5.8.7-r3.tbz2 -C /srv/jailtest/
# install different, missing libraries (see messages when trying to run 
# test.pl):
jk_cp -v /srv/jailtest/ /lib/libxyz.so.x
# install missing executables:
jk_cp -v /srv/jailtest/ /bin/dirname
jk_cp -v /srv/jailtest/ /bin/pwd
jk_cp -v /srv/jailtest/ /bin/basename
# "login" to jail and execute script
su - jailuser
./test.pl

output:
bash-3.00$ ./test.pl 
$0: ./test.pl
pgm: not_set
working_dir: not_set
$0: ./test.pl
pgm: test.pl
working_dir: /home/jailtest1

Cheers,
Stephen
