> Having searched just about everywhere else, in search of the answer to this question I'm searching here. What was (in the past) the use of the R: ?
R: lines enabled admins to establish different policies about users connecting, rather than the simple authorization methods allowed by I: and K: lines. I would suppose they are still useful on smaller networks, but on a network such as Undernet, the number of clients connecting would result in too much CPU usage, and thus, lag. Also, they are most useful when the user connecting is local, so that the program run can access more information about the user. I suspect they were used with more frequency in the earlier days of IRC when nearly all users connected via their college network, to an IRC server that was also on the school network, so that school network use policies could be enforced without having to implement them into the ircd. -- Aurorian
