the notify.txt that is sent to players
--------------------------------------

Subject: the Armageddon game processed

Your turn is ready at
dom3minions.com

(courtesy of Gandalf Parker at Any1can.net)

----------------------------------------

the notification could also be changed to include the turn number. It could also easily be changed to include emailing the turn file.

Which makes you automatically think PbEM. If a game had its own email address such as armageddon@dom3minons.com then something like procmail could manage incoming emails to place the .2h files (which means "to host") into the game directory. It could also kick off a script to check for all turns being in and then run/quit the host. This would raise the number of games that a server can run by many levels.

I just realized that maybe this will interest some people....

OK all of you Linux people. Have fun with THIS one. This is my bl_game.sh for creating small blitz games.

Some highlists on that blitz script...

It selects random opponents (presently rem'd out in its use)

It selects a random port and it tests to see if that port is in use

It creates a random password and uses that as the master password for the game

It chooses a random word from the system spelling dictionary and uses that as the game name (some very interesting results have come from that)

It chooses a random era

It creates a random map for the game of 640x480 and 30 provinces. Suitable for a 2 or 3 player blitz game

It creates a game log and a game error file

It adds the games description (game name, port, settings) to a BLITZ_games.txt so that if I whip off 10 quick new games I can just upload that text to announce them

It creates a quick-kill shell in the games directory

It creates pre and post shells.

Sets up the pre shell to move the blitz map to the game directory once the game starts. That saves on cleanup of the games later.

Sets up the post shell to rotate the logs which can get very large depending on how many d's you use on the games command line

Any questions?

[Neophyte]

Does the IP address need to be specified (in the script) if one is IP forwarding through a firewall? If so, the address needs to be the address that remote clients will be using, correct? I hope I got the terminology right.

Thank's!

[Gandalf Parker]

I understand your question but Im afraid that I dont know the answer. I dont know of any way to tell the game which IP to run on. I think that when hosting, the game only concerns itself with port. So if the clients address hits the firewall, and the firewall forwards it to the right machine, things should be transparent to the user. But Im afraid thats just guesswork on my part.

By the way, Dom3 handles both IP or domain name for the server. Thats something I have tested quite abit. So Im able to send people to either 63.199.8.158 OR dom3minions.com for a game. (also 63.199.8.157 host.dom3minions.com which I use for blitz games)

[Neophyte]

Upon reflection, the whole IP thing is probably a switch issue not a computer issue anyhow - i.e. addyXZ internally is in all ways equivalent to addyYZ externally with IP forwarding setup. Should have thought of this last night, but it was late, and my networking knowledge is sporadic.

Thank's for the reply - I'll test out your scripts once Dom3 shows up hopefully next week.

PbEM scripting has been ironed out. The key is two switches which will start a game hosting automatically. The thread where this was discussed fully is at
http://www.shrapnelcommunity.com/thr...270&Forum=f187

The switches are:
--uploadtime
--uploadmaxp
