Yes, CGI can be used, which can be coded in Perl, C/++, Python and
other's. They can use combinations (or only) of CGI, PHP, ASP, Java,
etc. Many, many things are used, it depends on what you know best, and
what works best on said web server's OS/web server, etc. That's a very
vague question.

Do we have ASP for any OS other than Windows yet? If not, why bother even
mentioning it?
ASP is pretty good, but as long as it's locked up on Windows, there is no
need to bother with
it. Same goes to VBScript and JScript, both of which are okay for server
side work.
If I am just out of date, please tell me...

Subject: running a service as root
Message-Id: <PBPT4.17$e61.7873@dummy.bahnhof.se>
I have written a client and server based unixsystem administration
tool. The ide' is to install the server on several machines and the client
on one protected(no user access) server. I can then use a webinterface on
my client machine to administrate all my servers.
For the servercode to be able to do the things i want it to it has to
run as root. I don't like it but in this case it is a must.
1. I run it as a service through inetd(tcp) with a tcp-wrapper.
2. I have incode ip and user/password authentication.
3. All comunication between client and server is encrypted with
Crypt::Twofish.
4. All server->system activity that don't require root access is run as the
user
it effects(eg. when creating a file i a user directory, do it as the user.)
- Still to be implemented.
5. All system calls are run with "exec 'program', '$arg1', '$arg2'" where
all
$args are matched with regexps.
I would be happy for any suggestions in making my client-server more secure.
I know that buffer owerflows is a classic way to hack servers. What is the
best way to
prevent/avoid buffer overflow.

Run the ".pl"? What's a .pl?

Check that call:
open (STATSLOG, "$userstatslog") or die "Open failed for $userstatslog
$!";
Also, look into something called "file locking".

Check your call. (refer to above).
Lock the file...

Why do you write another tab delimiter at the end for?
> close(SLOG);
Check the call...
Read the Perl Docs and other help/information. Maybe buy a book? It's
hard to explain problems, if you don't understand enough about it to
avoid all of them. Basically, you'll end up having other's write it for
you, in which case you learn nothing and you have the same problems
again. Maybe you just neglected to provide the other information in your
code?

I completely neglected to mention the above. You already have @STATData
= <STATSLOG>, so why do a for loop and then split to assign each field?
You already have the array and values, no need to for loop and step
through it just to create, or re-create another/same one. Just split the
fields of the array you already have.

Thats fine and dandy but it isnt reporting the :
"Can't "last" outside a loop block at ... "
error message which would have been useful. Read what it says about that
message in the perldiag manpage.

This is because a fetch of any sort is meaningless with a query that doesnt
return any rows such as an insert, delete or update. The execute() is
all that you need or alternatively you can use do().

Subject: WoT MUD Looking for Coder who knows Perl
Message-Id: <8foge0$ls8$1@nnrp1.deja.com>
Our MUD is a project in the works, based on Robert Jordan's Wheel of
Time novels, but centered to open in Pre-Trolloc Wars era. We’re at a
very exciting stage right now as we've opted to base the MUD in a time
where we knew little to nothing about the cultures and countries of the
world, and so this gives us not just the adequate space to be creative
and in a way create our own world, but it lessens the frustration of
starting everything from scratch by giving us a general basic concept
to structure all our ideas upon.
Our MUD has been in existence for nearly two and a half years now.
While work has gone slowly up until now, we have three cities in the
works, as well as some firm ideas on a complex fight system that just
waits for a coder to put it into effect. We recently decided to switch
our time period from the time of the books to one that will allow us
more freedom. Most of what needs to be done at this point will be idea
work and coding.
The staff we'd like to acquire is one not just of coders, but one of
people who have ideas and wish to see them go through and become
reality to our world. We currently have two Imps who are overseeing the
creation of cultures, as well as a few staff members who are working on
a very advanced and exciting fight system for the code.
Head Coder and Assistants:
We're looking for a Head Coder who is willing to take on a few
assistants as they may appear and who has a good knowledge of Perl, SQL
and C, as our codebase has been greatly modified from its original
structure. Assistant Coders must be willing of course, to work with the
Head Coder and be people persons as well as quick learners. Whereas the
Head Coder will work on bigger projects, the Assistant Coders will
mostly be working on smaller things, as well as helping the HC where
she/he may need it.
If at all interested, please send a mail to srm@missupportservices.com
and rynaln@hotmail.com with who you are, your background and experience
with the Wheel of Time series, Building in OLC or coding in Perl, SQL
and C, depending of course, on the position you wish to apply for.
Also, if you're applying to be a builder, please include a sample
description of your work, hopefully on a room or whatever you may
specialize in, be it objects, rooms or mobs.
Thanks!
