* irc[d] configuration options.
* Most of the following defines are related to the server,
* some apply to the client.
* If you don't want the server to keep reading the MOTD file from the disk,
* define CACHED_MOTD. The server will store the MOTD in memory, and only
* read it again from the disk when rehashing if the file has changed.
* Define for value added security if you are a rooter.
* CPATH, MPATH, LPATH, PPATH, TPATH, QPATH, OPATH,
* FNAME_USERLOG, FNAME_OPERLOG, FNAME_CONNLOG, FNAME_AUTHLOG
* must have RPATH as root directory! Set them in Makefile
* You may want to define IRC_UID and IRC_GID
#define ROOT_PATH "/where/to/change/root/dir"
* The SUMMON command requires the ircd to be run as group tty in order
* to work properly in many cases. If you are on a machine where it
* won't work, or simply don't want local users to be summoned, undefine
#undef ENABLE_SUMMON /* local summon */
#undef ENABLE_USERS /* enables local /users (same as who/finger output) */
* As defined this will show the correct invisible count for anyone who does
* LUSERS on your server. On a large net this doesnt mean much, but on a
* small net it might be an advantage to undefine it.
* When defined, your users will not automatically be attributed with user
* mode "i" (i == invisible). Invisibility means people dont showup in
* WHO or NAMES unless they are on the same channel as you.
* If you dont believe operators should be allowed to use the /KILL command
* or believe it is uncessary for them to use it, then leave OPER_KILL
* undefined. This will not affect other operators or servers issuing KILL
* commands however. OPER_REHASH and OPER_RESTART allow operators to
* issue the REHASH and RESTART commands when connected to your server.
* Left undefined they increase the security of your server from wayward
* operators and accidents. Defining OPER_REMOTE removes the restriction
* that O-lines only become fully effective for people on the 'same network'
* as the server. Undefined, it increases the security of the server by
* placing restrictions on where people can use operator powers from.
* The 'LOCOP_' #defines are for making the respective commands available
* to 'local' operators. Note that the 'OPER_' #defines affect both global
* (big O) and local (little o) operators. Defining 'LOCOP_x' has no effect
* if 'OPER_x' is undefined so you can't give local operators more rights
* than global ones.
* Maximum number of network connections your server will allow. This should
* never exceed max. number of open file descrpitors and wont increase this.
* Should remain LOW as possible. Most sites will usually have under 50 or so
* if you have a lot of server connections, it may be worth splitting the load
* over 2 or more servers.
* 1 server = 1 connection, 1 user = 1 connection.
* This should be at *least* 4: 2 listen ports (1 tcp, 1 udp)
* 1 dns port, 1 client
#define MAXCONNECTIONS 50
/* MAXIMUM LINKS
* This define is useful for leaf nodes and gateways. It keeps you from
* connecting to too many places. It works by keeping you from
* connecting to more than "n" nodes which you have C:blah::blah:6667
* lines for.
* Note that any number of nodes can still connect to you. This only
* limits the number that you actively reach out to connect to.
* Leaf nodes are nodes which are on the edge of the tree. If you want
* to have a backup link, then sometimes you end up connected to both
* your primary and backup, routing traffic between them. To prevent
* this, #define MAXIMUM_LINKS 1 and set up both primary and
* secondary with C:blah::blah:6667 lines. THEY SHOULD NOT TRY TO
* CONNECT TO YOU, YOU SHOULD CONNECT TO THEM.
* Gateways such as the server which connects Australia to the US can
* do a similar thing. Put the American nodes you want to connect to
* in with C:blah::blah:6667 lines, and the Australian nodes with
* C:blah::blah lines. Have the Americans put you in with C:blah::blah
* lines. Then you will only connect to one of the Americans.
* This value is only used if you don't have server classes defined, and
* a server is in class 0 (the default class if none is set).
#define MAXIMUM_LINKS 1
* A pure non-routing leaf server can undefine HUB for best performance.
* If your server is running as a a HUB Server then define this.
* A HUB Server has many servers connect to it at the same as opposed
* to a leaf which just has 1 server (typically the uplink).
/* #define HUB */
* MAXSERVERS is the maximum number of servers that will be linked
* to your server at the same time. This number is not a limit,
* it is used to allocate memory when ircd is started.
# define MAXSERVERS 3
# define MAXSERVERS 1
* If you want to use timed klines, set it to frequence in seconds,
* how often to check if client is to be removed; usually 60 seconds
* (smallest granularity you can get in K:line anyway).
* Advised not to use it ;-) --Beeth
/* R_LINES: The conf file now allows the existence of R lines, or
* restrict lines. These allow more freedom in the ability to restrict
* who is to sign on and when. What the R line does is call an outside
* program which returns a reply indicating whether to let the person on.
* Because there is another program involved, Delays and overhead could
* result. It is for this reason that there is a line in config.h to
* decide whether it is something you want or need. -Hoppie
* The default is no R_LINES as most people probably don't need it. --Jto
/* Also, even if you have R lines defined, you might not want them to be
checked everywhere, since it could cost lots of time and delay. Therefore,
The following two options are also offered: R_LINES_REHASH rechecks for
R lines after a rehash, and R_LINES_OFTEN, which rechecks it as often
as it does K lines. Note that R_LINES_OFTEN is *very* likely to cause
a resource drain, use at your own risk. R_LINES_REHASH shouldn't be too
bad, assuming the programs are fairly short. */
* NOTE: defining CMDLINE_CONFIG and installing ircd SUID or SGID is a MAJOR
* security problem - they can use the "-f" option to read any files
* that the 'new' access lets them. Note also that defining this is
* a major security hole if your ircd goes down and some other user
* starts up the server with a new conf file that has some extra
* O-lines. So don't use this unless you're debugging.
#undef CMDLINE_CONFIG /* allow conf-file to be specified on command line */
* To use m4 as a preprocessor on the ircd.conf file, define M4_PREPROC.
* The server will then call m4 each time it reads the ircd.conf file,
* reading m4 output as the server's ircd.conf file.
* If you wish to have the server send 'vital' messages about server
* through syslog, define USE_SYSLOG. Only system errors and events critical
* to the server are logged although if this is defined with FNAME_USERLOG,
* syslog() is used instead of the above file. It is not recommended that
* this option is used unless you tell the system administrator beforehand
* and obtain their permission to send messages to the system log files.
* If you use syslog above, you may want to turn some (none) of the
* spurious log messages for KILL/SQUIT off.
#undef SYSLOG_KILL /* log all operator kills to syslog */
#undef SYSLOG_SQUIT /* log all remote squits for all servers to syslog */
#undef SYSLOG_CONNECT /* log remote connect messages for other all servs */
#undef SYSLOG_USERS /* send userlog stuff to syslog */
#undef SYSLOG_OPER /* log all users who successfully become an Op */
#undef SYSLOG_CONN /* log all uncomplete/rejected connections */
* If you want to log to a different facility than DAEMON, change
* this define.
#define LOG_FACILITY LOG_DAEMON
#endif /* USE_SYSLOG */
* define this if you want to use crypted passwords for operators in your
* ircd.conf file. See contrib/mkpasswd/README for more details on this.
* If you want to store encrypted passwords in N-lines for server links,
* define this. For a C/N pair in your ircd.conf file, the password
* need not be the same for both, as long as hte opposite end has the
* right password in the opposite line. See INSTALL doc for more details.
* define this if you enable summon and if you want summon to look for the
* least idle tty a user is logged in on.
* Idle-time nullified only from privmsg, if undefined idle-time
* is nullified from everything except ping/pong.
* Added 3.8.1992, email@example.com (nam)
* use these to setup a Unix domain socket to connect clients/servers to.
* If you start the server as root but wish to have it run as another user,
* define IRC_UID to that UID. This should only be defined if you are running
* as root and even then perhaps not.
#define IRC_UID 65534 /* eg for what to do to enable this feature */
#define IRC_GID 65534
* this controls the number of bytes the server will allow a client to
* send to the server without processing before disconnecting the client for
* flooding it. Values greater than 8000 make no difference to the server.
#define CLIENT_FLOOD 1000
/* Remote query flood protection. */
#define CHREPLLEN 8192
/* Default server for standard client */
#define UPHOST "irc"
* If you wish to run services, define USE_SERVICES.
* This can make the server noticeably bigger and slower.
* services are not fully implemented yet, so don't use it unless you really
* know what you are doing.
* Define the following to make the delay for nicks random.
* Some people believe a bot can exactly time the delay and don't like it,
* I think this is a useless concern. -krys
* You've read the BOFH saga and you liked it, then define the following.
* The two following will change the nick delay and channel delay features
* making them totally user unfriendly but more efficient.
* Defining this will enable the use of compressed server-server links.
* In order to have it work, you must have the zlib version 1.0 or higher.
* The library and the include files must have been found by configure,
* if you have installed the zlib after running configure, run it again.
* Defining this will add an artificial 2 seconds delay for accepting
* connections. This is the OLD behaviour of the server.
* NOTE: Undefining this leads to a significant increase in CPU usage if
* you reject client which keeps connecting.
* Defining this will make the server check for rapid connections from a single
* host and reject new connections from this host if the limit is reached.
* NOTE: Enabling this feature will significantly increase the CPU usage
* for servers carrying several hundred clients and getting many connections.
* IMPORTANT: This **MUST** defined if SLOW_ACCEPT is NOT defined
* Because ip6.arpa is still not delegated for the 6bone (3ffe::/16)
* this options allows you to still resolve it using ip6.int.

/* You shouldn't change anything below this line, unless absolutely needed. */
* To be used, OPER_KILL must be defined.
* LOCAL_KILL_ONLY restricts KILLs to clients which are connected to the
* server the Operator is connected to (ie lets them deal with local
* problem users or 'ghost' clients
/* Default server port, used by client. */
#define PORTNUM 6667

#define LISTENQUEUE 128
/* define DEBUGMODE to enable debugging mode.*/
* Time interval to wait and if no messages have been received, then check for
* PINGFREQUENCY and CONNECTFREQUENCY
#define TIMESEC 60 /* Recommended value: 60 */
* If daemon doesn't receive anything from any of its links within
* PINGFREQUENCY seconds, then the server will attempt to check for
* an active link with a PING message. If no reply is received within
* (PINGFREQUENCY * 2) seconds, then the connection will be closed.
#define PINGFREQUENCY 120 /* Recommended value: 120 */
* If the connection to to uphost is down, then attempt to reconnect every
* CONNECTFREQUENCY seconds.
#define CONNECTFREQUENCY 600 /* Recommended value: 600 */
* Often net breaks for a short time and it's useful to try to
* establishing the same connection again faster than CONNECTFREQUENCY
* would allow. But, to keep trying on bad connection, we require
* that connection has been open for certain minimum time
* (HANGONGOODLINK) and we give the net few seconds to steady
* (HANGONRETRYDELAY). This latter has to be long enough that the
* other end of the connection has time to notice it broke too.
#define HANGONRETRYDELAY 30 /* Recommended value: 30 seconds */
#define HANGONGOODLINK 900 /* Recommended value: 15 minutes */
* Number of seconds to wait for write to complete if stuck.
#define WRITEWAITDELAY 15 /* Recommended value: 15 */
* Number of seconds to wait for DNS/authentication to complete.
* Note that iauth's default timeout per module is 30 seconds, so this value
* should be at least 30 * number of modules. Extra time should really be
* given to be safe.
#define ACCEPTTIMEOUT 90 /* Recommended value: 90 */
* Max time from the nickname change that still causes KILL
* automaticly to switch for the current nick of that user. (seconds)
#define KILLCHASETIMELIMIT 90 /* Recommended value: 90 */
* Max time for the channel history and nick delay to be effective.
* It should be the same value on all servers of a same net, and
* be greater than the split durations usually seen.
* DELAYCHASETIMELIMIT is the default.
#define DELAYCHASETIMELIMIT 1800 /* Recommended value: 1800 */
* Max time for !channel history, this *MUST* be fairly long (usually
* much longer than the value above) to ensure shortname unicity.
* It makes very little sense to use a short time limit here.
#define LDELAYCHASETIMELIMIT 5400 /* Recommended value: 5400 */
* Max number of channels a user is allowed to join.
#define MAXCHANNELSPERUSER 10 /* Recommended value: 10 */
* USE_IAUTH makes ircd use the iauth program for authentication.
* it can always be overriden by using the -s switch
* the compression level used. (Suggested values: 3, 4, 5)
* Above 5 will only give a *very* marginal increase in compression for a
