There are some important limitations to consider when running CGI scripts on Tripod. Certain Perl commands have been disabled for security reasons. This is to prevent
people from performing such malicious acts as reading your private directories. People doing normal Web-site programming very rarely use most of these commands, but
there are a few more common commands that you might want to know about. These are:
system
exec
fork
chown
chmod
sleep
unlink
kill
eval
All commands involving sockets
We've also limited how many system resources are available to each script. For example, a script can only use up to one second of CPU time before it is deemed to be
causing problems and is terminated. This ensures that users don't accidentally -- or intentionally -- write scripts that run endlessly and eat up all of the server's
resources. It's unlikely that you'll run into system-resource constraints unless you're running a script which requires an exceptional amount of processing time
or memory.
