Having had a few problems with some users misusing the IP's posted to channel. We was looking to modify it to work on say. wfc<nick> <<--<nick>being the nick of the other player.And it would be via notice And also a notice to Chanops, so they can ensure
the IP has resolved correctly.
Any ideas help in this would be most appreciated.
# wfc is a means by which non-technical users can advertise their host and IP
# addresses in channel. This script generates the same output as the original
# wfc used by #ScrabbleOn and its siblings. However, this script will reveal
# information for +x users, which the original version could not do.
#
# Note that this version will run slightly slower than the original, as it
# waits for a /whois reply before processing the nslookup.
#
# Requirements for the bot running this script:
# * A shell with nslookup available (this was an existing requirement).
# * At least local IRCOp privileges (to reveal information on +x users).
# * A network running the Unreal ircd (see the notes on RAW 378).

bind pubm -|- "% wfc" do_wfc
bind raw - 378 wfc:whois_reply
bind raw - 318 wfc:whois_reply
###############################################################################
# This procedure is triggered by a user's request to reveal his or her
# information. If the user is -x his/her address is already available, but
# without reading their flags we don't know if it's legitimate or masked.
# So, we always issue a /whois to see what response we get.
#
# We save the user's channel and (supposed) host address to global arrays
# keyed off of the user's nick, so we can retrieve them in the /whois
# handler. Since they're global (and therefore "sticky") and not cleared
# here, we set timers to unset them in case the /whois doesn't go through;
# this prevents us from generating useless variables that don't expire.
#
# Note that, since the nick becomes part of a variable name, we have to
# strip out any special characters before creating the variable. This will
# only cause a problem if two people whose nicks resolve to the same result
# (e.g., Me[away] and Me{away}) both did a wfc at approximately the same time.

# This procedure handles raw numerics 378 and 318 returned from a /whois.
#
# * 318 is a standard "End of /whois" message.
# * 378 includes the full unmasked host address of the target.
#
# (Note that a 378 is only sent if the target is +x AND the bot is an IRCOp.
# Note also that a 378 and its format are specific to the Unreal ircd; for
# example, PTLink uses a differently-formatted raw 616 for this function.)
#
# If a 378 is received, parse out the user's host address and store it over
# top of the one that was originally retrieved (since the latter is now
# known to be masked).
#
# When a 318 is received, grab the user's host address and pass it to
# nslookup, then process the results and display them in channel.
#
# Note that the array "addr" is set global only so that data stored in it
# will be "sticky" and be retained from the 378 to the 318... in other words,
# the equivalent of C's "static."
