27 * Definitions used everywhere in the server
28 * NOTE: Changing any of these definitions is equivalent to a protocol
29 * revision. Every server on a given network must also use the same sizes.
33 * NETWORK is the name the server claims the network is
35 #define NETWORK "UnderNet"
38 * URL_CLIENTS is a URL to where to find compatible clients
40 #define URL_CLIENTS "ftp://ftp.undernet.org/pub/irc/clients"
43 * NICKLEN is the maximum length allowed for a nickname
45 * Because certain networks are very helpful in finding bugs, the below
46 * is a default that can easily be overridden in CFLAGS. Just add
47 * -DNICKLEN=15 to CFLAGS and save your config in .., and you can forget about
48 * it. Thanks for helping debug guys.
54 * USERLEN is the maximum length allowed of a user name including an optional
55 * leading '~' if the user name has not been authenticated by an auth (RFC 931)
60 * HOSTLEN is exactly long enough to hold one (1) segment of FQDN or hostname.
61 * This is due to an historical misinterpretation of RFC 1034.
62 * 3.1. Name space specifications and terminology
64 * The domain name space is a tree structure. Each node and leaf on the
65 * tree corresponds to a resource set (which may be empty). The domain
66 * system makes no distinctions between the uses of the interior nodes and
67 * leaves, and this memo uses the term "node" to refer to both.
69 * Each node has a label, which is zero to 63 octets in length. Brother
70 * nodes may not have the same label, although the same label can be used
71 * for nodes which are not brothers. One label is reserved, and that is
72 * the null (i.e., zero length) label used for the root.
74 * This has proven not to be a problem in the past as connections with FQDN's
75 * of greater than 63 characters are rejected by the server, and most FQDN's
76 * are shorter. It is possible to have a valid FQDN longer than 63 characters.
80 * ACCOUNTLEN is the maximum length for the account name, which can be set
81 * with the ACCOUNT (AC) command. This is used for keeping track of who's
82 * logged into which account, for the benefit of irc services.
86 * REALLEN is the maximum length for user supplied information about a client
87 * connection (gcos). This information is set at client/server registration
92 * PASSWDLEN is the maximum length for a password used for connecting servers
97 * SOCKIPLEN is the length of a dotted quad ip address "XXX.XXX.XXX.XXX"
101 * TOPICLEN is the maximum length for channel topics and kill comments
105 * AWAYLEN is the maximum length for away messages
109 * BUFSIZE is exactly long enough to hold one protocol message (RFC 1459)
110 * including the line termination (\r\n).
