Firstly set an environment variable JNET to point to the installation directory, i.e. if installed in /homes/james/ setenv JNET /homes/james/jnet (for sh, csh, tcsh) or export JNET=/homes/james/jnet (for bash)
All the perl scripts in the perl dir will need there #!CHANGEJNET headers changing to direct the script to the perl interuptor, which is usually /usr/loca/bin/perl. The script $JNET/perl/change_header will do this for you if you have sed and sh. Change directory to the Perl installation directory and run the script from there. Perl 5 is a requirement for all the scripts in Jnet.
*SGI ONLY* If using an older SGI machine (r4000), rename the jnet_mips2 binary to jnet. The original jnet binary was optimised for the R10,000, mips4 architecture.
