Don't use IO::Socket. You're on the right track with LWP::Simple, and LWP has some other classes that give you finer grain control, like LWP::UserAgent. > > >You install libwww-perl using the normal perl module > distribution drill: > > > > perl Makefile.PL > > make > > make test > > make install > > I executed the first instruction with prefix option.

I would suggest you go right with the host faq and create /home/user/perl. Then untar the distribution in some other directory (say /home/user/build). Go to /home/user/build and enter: perl Makefile.PL PREFIX=/home/user/perl That should create a Makefile (not makefile) in your /home/user/build directory. Now you can do: make make test make install That should drop the files in the right place in directories below /home/user/perl (e.g. /home/user/perl/LWP/Simple.pm). Now, in your script: use lib '/home/user/perl'; use LWP::Simple; should work. The build/install instructions will be the same no matter what modules you're installing (i.e. *always* use PREFIX=/home/user/perl and *always* use lib '/home/user/perl') -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
