ircu snowmasks list

These descriptions are current up to ircu2.10.11 alpha. The most current description of these values can be found in the ircu source code in the file include/client.h

This document (hopefully) gives a brief explanation of the use of server notice masks new to ircu2.10.xx.
This mask allows clients to specify which types of server notices they will receive when usermode +s.
The mask may optionally be omitted, and reasonable defaults will be used by the server.

*Note* the descriptions here will be best understood by those with knowledge of C syntax.
We do not attempt to explain either this or hexadecimal values in this document and familiarity with these is assumed of the reader.

Usage: /mode <nick> +s [+/-][mask]

Mask		Hex value	Description
1	    SNO_OLDSNO	0x1	/* unsorted old messages */
2	    SNO_SERVKILL	0x2	/* server kills (nick collisions) */
4	    SNO_OPERKILL	0x4	/* oper kills */
8	    SNO_HACK2	0x8	/* desyncs */
16	    SNO_HACK3	0x10	/* temporary desyncs */
32	    SNO_UNAUTH	0x20	/* unauthorized connections */
64	    SNO_TCPCOMMON	0x40	/* common TCP or socket errors */
128  	SNO_TOOMANY	0x80	/* too many connections */
256	    SNO_HACK4	0x100	/* Uworld actions on channels */
512	    SNO_GLINE	0x200	/* glines */
1024	SNO_NETWORK	0x400	/* net join/break, etc */
2048	SNO_IPMISMATCH	0x800	/* IP mismatches */
4096	SNO_THROTTLE	0x1000	/* host throttle add/remove notices */
8192	SNO_OLDREALOP	0x2000	/* old oper-only messages */
16384	SNO_CONNEXIT	0x4000	/* client connect/exit (ugh) */
32768	SNO_DEBUG	0x8000	/* only applies to servers compiled in debug mode (NOT production servers) */


standard +s	SNO_DEFAULT (SNO_NETWORK | SNO_OPERKILL | SNO_GLINE)
standard +s when +o/O	SNOSNO_OPER (SNO_DEFAULT | SNO_HACK2 | SNO_HACK4 | SNO_THROTTLE | SNO_OLDSNO)
only opers may set	SNO_OPER (SNO_CONNEXIT | SNO_OLDREALOP)


Examples of usage:

To receive only operkills, use:
/mode <nick> +s 4

To receive operkills and glines, add the values:
/mode <nick> +s 516 (512+4=516)

If you are already receiving some notices and you wish to add notices of netjoins/breaks use:
/mode Ghostwolf +s +1024

If you wish to stop receiving netjoin/break notices, but continue to receive other notices, use:
/mode Ghostwolf +s -1024 or
/mode Ghostwolf -s +1024

A user doing:
/mode Ghostwolf +s
will receive netsplits/joins, operkills, and g-lines.

Opers who are +s will additionally receive HACK notices and anything that was originally in sendto_ops() and wasn't changed.
Only opers can choose to receive connect/exit notices and anything that originally was in sendtoreal_ops() and hasn't been changed (connect/exit notices also require a #define in config.h).
If you have further questions about server notices (implementation, etc.), please consult the ircu source code and/or e-mail coder-com@undernet.org.
