Options are:
--args <filename>
Read the options from <filename> as if they were given on the
commandline.
-P|--inherit <fd-number>
Inherit filedescriptor <fd-number> from the parent process as
socket to listen for connections.
-u|--udp <portnumber>
Specify the <portnumber> for the UDP port, overriding the com‐
piled-in default.
-D|--define <macro>[=<text>]
Add <macro> (optionally to be expanded to <text>) to the list of
predefined macros known by the LPC compiler.
-E|--eval-cost <ticks>
Set the number of <ticks> available for one evaluation thread.
-M|--master <filename>
Use <filename> for the master object.
-m|--mudlib <pathname>
Use <pathname> as the top directory of the mudlib.
--debug-file <filename>
Log all debug output in <filename> instead of <host>.debug.log .
--access-file <filename>|none
Activate access control with these access permissions data. If
'none' is given access control is deactivated.
--access-log <filename>|none
Log valid and rejected connections into this file. If 'none' is
given no log is written.
--hostname <name>
Use <name> as hostname, instead of what the system says.
--hostaddr <addr>
Use <addr> as address of this machine, instead of what the sys‐
tem says. In particular this address will be used to open the
driver ports.
--compat
--no-compat
Select the mode (compat or plain) of the driver. Note that this
choice does not affect the default name of the master object.
-d|--debug
Generate debug output; repeat the argument for even more output.
-c|--list-compiles
List the name of every compiled file on stderr.
-e|--no-preload
Pass a non-zero argument (the number of occurences of this
option) to master->preload(), which usually inhibits all
preloads of castles and other objects.
--erq <filename>
--erq "<filename> <erq arguments>"
Use <filename> instead of 'erq' as the name of the ERQ exe‐
cutable. If the name starts with a '/', it is take to be an
absolute pathname, otherwise it is interpreted relative to
/usr/local/sbin. If not specified, 'erq' is used as executable
name. With the proper use of quotes it is legal to pass arbi‐
trary arguments to the erq, however, these may not contain spa‐
ces themselves.
-N|--no-erq
Don't start the erq demon (if it would be started at all).
--alarm-time <time>
The granularity of call_out()s and heartbeats (minimum: 1).
--heart-interval <time>
The time to elapse between two heartbeats (minimum: 1).
--sync-heart
All heartbeats are executed at the same time (modulo granular‐
ity).
--async-heart
Heartbeats are executed immediately when they are due (modulo
granularity).
-t|--no-heart
Disable heartbeats and call_outs.
-f|--funcall <word>
The lfun master->flag() is called with <word> as argument before
the gamedriver accepts network connections.
--cleanup-time <time>
The idle time in seconds for an object before the driver tries
to clean it up. This time should be substantially higher than
the reset time. A time <= 0 disables the cleanup mechanism.
--reset-time <time>
The time in seconds for an object before it is reset. A time <=
0 disables the reset mechanism.
--regexp pcre|traditional
Select the default regexp package.
--max-array <size>
The maximum number of elements an array can hold. Set to 0,
arrays of any size are allowed.
--max-callouts <number>
The maximum number of callouts at one time. Set to 0, any num‐
ber of callouts is allowed.
--max-mapping <size>
The maximum number of elements (keys+values) a mapping can hold.
Set to 0, mappings of any size are allowed.
--max-mapping-keys <size>
The maximum number of entries (keys) a mapping can hold. Set to
0, mappings of any size are allowed.
--max-bytes <size>
The maximum number of bytes one read_bytes()/write_bytes() call
can handle. Set to 0, reads and writes of any size are allowed.
--max-file <size>
The maximum number of bytes one read_file()/write_file() call
can handle. Set to 0, reads and writes of any size are allowed.
--max-write-buffer <size>
The maximum number of bytes to be kept pending for each socket
to write. Set to 0, an unlimited amount of data can be kept
pending.
-s <time>
| --swap-time <time>
-s v<time> | --swap-variables <time>
Time in seconds before an object (or its variables) are swapped
out. A time less or equal 0 disables swapping.
-s f<name> | --swap-file <name>
Swap into file <name> instead of LP_SWAP.<host> .
-s c | --swap-compact
Reuse free space in the swap file immediately.
--hard-malloc-limit <size>
Restrict total memory allocation to <size> bytes. A <size> of 0
or 'unlimited' removes any restriction.
--soft-malloc-limit <size>
If total memory allocation exceeds <size> bytes, inform the
mudlib master about a developing low memory situation. A <size>
of 0 or 'unlimited' removes the threshold. <size> must be
smaller than --hard-malloc-limit.
--min-malloc <size>
--min-small-malloc <size>
Determine the sizes for the explicite initial large resp. small
chunk allocation. A size of 0 disables the explicite initial
allocations.
-r u<size> | --reserve-user <size>
-r m<size> | --reserve-master <size>
-r s<size> | --reserve-system <size>
Reserve <size> amount of memory for user/master/system alloca‐
tions to be held until main memory runs out.
--filename-spaces
--no-filename-spaces
Allow/disallow the use of spaces in filenames.
--strict-euids
--no-strict-euids
Enforce/don't enforce the proper use of euids.
--share-variables
--init-variables
Select how clones initialize their variables:
- by sharing the current values of their blueprint - by initial‐
izing them afresh (using __INIT()).
--tls-key <pathname>|none
Use <pathname> as the x509 keyfile, default is 'key.pem'. If
relative, <pathname> is interpreted relative to <mudlib>. If
'none' is given TLS is deactivated.
--tls-cert <pathname>
Use <pathname> as the x509 certfile, default is 'cert.pem'. If
relative, <pathname> is interpreted relative to <mudlib>.
--tls-trustfile <pathname>|none
Use <pathname> as the filename holding your trusted PEM certifi‐
cates,
default is 'none'.
If relative, <pathname> is interpreted relative to <mudlib>.
--tls-trustdirectory <pathname>|none
Use <pathname> as the directory where your trusted PEM certifi‐
cates reside,
default is 'none'.
If relative, <pathname> is interpreted relative to <mudlib>.
--tls-crlfile <pathname>|none
Use <pathname> as the filename holding your certificate revoca‐
tion lists,
default is 'none'.
If relative, <pathname> is interpreted relative to <mudlib>.
--tls-crldirectory <pathname>|none
Use <pathname> as the directory where your certificate revoca‐
tion lists reside,
default is 'none'.
If relative, <pathname> is interpreted relative to <mudlib>.
--wizlist-file <filename>
--no-wizlist-file
Read and save the wizlist in the named file (always interpreted
relative the mudlib); resp. don't read or save the wizlist.
--pidfile <filename>
Write the pid of the driver process into <filename>.
--randomdevice <filename>
Determines the source of the seed for the random number genera‐
tor. (tries /dev/urandom by default and uses system clock as
fallback)
--random-seed <num>
Seed value for the random number generator. If not given, the
driver chooses a seed value on its own.
--gcollect-outfd <filename>|<num>
Garbage collector output (like a log of all reclaimed memory
blocks) is sent to <filename> (or inherited fd <num>) instead of
stderr.
--check-refcounts
Every backend cycle, all refcounts in the system are checked.
SLOW!
--check-state <lvl>
Perform a regular simplistic check of the virtual machine
according to <lvl>:
= 0: no check = 1: once per backend loop = 2: at various points
in the backend loop
--gobble-descriptors <num>
<num> (more) filedescriptors are used up. You'll know when you
need it.
--options
Print the version and compilation options of the driver, then
exit.
-V|--version
Print the version of the driver, then exit.
--longhelp
Display this help and exit.
-h|-?|--help
Display the short help text and exit.
