This
tutorial
will show you how to compile suidperl for Slackware so you can run Open
WebMail (OWM). Later versions of the perl package for Slackware don't
come with suidperl, so you have to download the package source and
compile the package yourself so you'll have suidperl. Once
suidperl is setup you can then setup SpeedyCGI so OWM will run faster.
This tutorial was written for Slackware 10.2 with perl 5.8.7 but
should also apply to other versions.
1. First, download the source for the perl package. Go to http://slackware.com/getslack/ and find a mirror near you. Once there go to the perl source directory (slackware-10.2/source/d/perl) and download all the files there.
2. Run the perl.SlackBuild script to first build the standard package.
3. Once that is done you'll need to edit the perl.SlackBuild script file. Go to the section that starts with "# Extract the source code:" You'll want to comment out the 'rm' and 'tar' lines:
#rm -rf perl-$VERSION
#tar xjvf $CWD/perl-$VERSION.tar.bz2
Next go to the configure section "# Configure perl:" and comment out the entire section:
#./Configure -de \
# -Dprefix=/usr \
# -Dcccdlflags='-fPIC' \
# -Dinstallprefix=/usr \
# -Doptimize="$SLKCFLAGS" \
# $USE_THREADS \
# -Dinc_version_list='5.8.6 5.8.5 5.8.4 5.8.3 5.8.2 5.8.1 5.8.0' \
# -Darchname=$ARCH-linux
Now add in a command to make sure we compile suidperl, go to "# Build perl" and add in a "make suidperl" line:
# Build perl6. Once the package is installed make sure the suid bit is set:
chmod +s /usr/bin/sperl5.8.7Depending upon the version of perl you are installing the filename will need to be changed.
That's all that's needed. Now just follow the OWM readme file and install the extra perl modules that are needed to run OWM. Once you get your installation of OWM up and running you can think about running it with SpeedyCGI to get a pretty good performance increase.
