2026.08.27(1) User Commands 2026.08.27(1) NAME 2026.08.27 - ldmud SYNOPSIS ldmud [options] [<portnumber>...] DESCRIPTION 2026.08.27 13:49:46 Seeding PRNG from /dev/urandom. LDMud 3.3.720 - a LP- Mud Game Driver. Release: Build 3010 (stable); 2011-02-22 Compiled: Aug 27 2026 13:49:32 Options are: --args <filename> Read the options from <filename> as if they were given on the com- mandline. -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 system 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 executable. If the name starts with a '/', it is take to be an absolute path- name, 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 arbitrary arguments to the erq, however, these may not contain spaces 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 granularity). --async-heart Heartbeats are executed immediately when they are due (modulo granu- larity). -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 number 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 alloca- tions. -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 allocations 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 initializing them afresh (using __INIT()). --tls-key <pathname>|none Use <pathname> as the x509 keyfile, default is 'key.pem'. If rela- tive, <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 rel- ative, <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 certificates reside, default is 'none'. If relative, <pathname> is interpreted relative to <mudlib>. --tls-crlfile <pathname>|none Use <pathname> as the filename holding your certificate revocation lists, default is 'none'. If relative, <pathname> is interpreted relative to <mudlib>. --tls-crldirectory <pathname>|none Use <pathname> as the directory where your certificate revocation 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 rel- ative 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 generator. (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.
