server/client program design advice wanted

[Junpei]

Hi, I basically want to create a server program in perl that does two
thing:
1) can receive a request, with parameters from the client to execute a
command with those parameter, and
2) executes the command, and returns some form of output (in this case
a a few 10kilobyte images).
whats the best way to do this? or is there a better way to do this
besides through perl? i've never done network programming so please be
nice .

There are many ways to do this. What is "best" depends on several
factors. Perl is certainly a good choice, as are other languages that
permit you to write TCP/IP servers, such as C, C++, Java, Python, and
no doubt others. Remote Procedure Call (RPC), and (on unix), rsh and
ssh will also let you execute programs remotely. You don't say what
your platform is.

If you want to use Perl, then you should check out the IO::Socket and
IO::Socket::INET modules. Also look at 'perldoc perlipc' for network
programming.

Be sure to check the incoming parameters from the client before
actually executing commands on your server system. To do otherwise is a
major security risk.
