Copying a MUSH

A family member wanted to create a new TinyMUSH using an existing one as a starting point. She felt it would be easier to modify the existing one than to start a new one from scratch. I took the steps detailed below to copy the existing MoonDreaming MUSH to a new one that she wanted to set up for SailorMoon roleplaying.

I shut down the original MUSH using the @shutdown command while logged into the MUSH as god. I then ran ./Backup from the command line.

$ ./Backup
Creating flatfile ./backups/moondreaming.1007-1558
Loaded module: comsys
Loaded module: mail
Using gdbm file: ./data/moondreaming.gdbm

Output: TinyMUSH-3 version 1: Zone Link Parent ExtFlags MoreFlags Powers QuotedStr TypedQuotas Timestamps VisualAttrs

Cleaned 1600 attributes (now 1376): 222 deleted, 186 renumbered (96 objects and 463 individual attrs touched).
Creating database archive ./backups/moondreaming.1007-1558.tar.gz
./backups/moondreaming.1007-1558
./data/mod_comsys.db
./data/mod_mail.db

I changed the working directory to the one containing the existing MUSH directory and then copied that directory and its subdirectories recursively.

$ cp -p -r moondreaming sailormoon

I then made the current working directory the one for the new MUSH.

$ cd sailormoon

I then edited mush.config in that directory. I changed the GAMENAME line to match the name of the new MUSH. I left the OWNER line the same, since the owner was the same person in this case.

GAMENAME=sailormoon

I then renamed the old conf file to match the new MUSH name and deleted the log and pid files from the other MUSH. The pid file contains the process id for the other MUSH process. A new one will be assigned the first time the new MUSH is run. If the pid file is not deleted, when you run Startmush it will state that the MUSH is already running.

$ mv moondreaming.conf sailormoon.conf
$ rm moondreaming.log*
$ rm moondreaming.pid

I also deleted the db directories that came from the other MUSH's directory.

$ rm -f -r db-*

I edited the new sailormoon.conf file I renamed to set the port for the new MUSH and its new name, changing the lines below within it.

crash_database  moondreaming.db.CRASH
gdbm_database   moondreaming.gdbm

port 7676
mud_name MoonDreamingMUSH

The new MUSH must listen on a different port than the existing MUSH and one that is not in use by any other application. You can use netstat -a | grep 9999 substituting the port number you've picked instead of 9999 to see whether an application is listening on that port. If no other process is listening on that port, at least at the time you run the command, you see the command prompt returned, but nothing else. Only the root account can use a port less than 1024; ports below that number are considered to be "reserved".

I changed the working directory to the data directory and renamed the old gdbm file to use the name associated with the new MUSH. I deleted the FLAT and KILLED files associated with the other MUSH.

$ cd data
$ ls
mod_comsys.db      mod_mail.db      moondreaming.FLAT  moondreaming.KILLED
mod_comsys.db.old  mod_mail.db.old  moondreaming.gdbm
$ mv moondreaming.gdbm sailormoon.gdbm
$ rm moondreaming.FLAT
$ rm moondreaming.KILLED

I then moved up to the main diectory for the MUSH and removed all of the backup files from the other MUSH, which are in the backups directory.

$ cd ..
$ ls
moondreaming.0310-2131.tar.gz  moondreaming.0316-1729.tar.gz
moondreaming.0315-1900.tar.gz  moondreaming.1007-1416.tar.gz
$ rm backups/*

I then ran ./Startmush


$ ./Startmush
./Startmush: line 83: [: : integer expression expected

Don't worry about the "integer expression expected", the first time the Startmush is run for the MUSH; it won't appear the next time you use Startmush.

After the MUSH loaded, I logged in as god and changed the password.

@password oldpassword=newpassword
Password changed.
