Proposal for EFNet Channel Fixer William Rockwood, March 28, 2001 Modified April 07, 2001 by William Rockwood PURPOSE: Prevent channels which lose ops from remaining in an oppless state. BACKGROUND: There have been a number of solutions proposed informally and even tried on the production EFnet network and each have and have had their own drawbacks. The common drawbacks among all of the ideas involve human resources or the time of operators to actually intervene. The reason for this resource drain is different in each case and more extreme in two. The Hybrid 7 implementation of 'vchans' requires an operator to create them, due to scaleability concerns if users were to create thousands of the same vchan. This creates an unacceptable amount of work for the operators and admins who have enough to do already with day to day maintenance of their own server, their day jobs, family life and what not. The EFNext (ircd-comstud-based) project implemented OJOIN and specified a means of aggregating the channel ops in every channel on the network which would be referenced by server operators when requested to assist with an oppless channel. The administrative overhead of this would also quickly become insane and is unreasonable. The patch for hybrid (infamously known as "OPME") was released, and run without a vote on several servers, and technically worked fine, but completely overlooked many issues which are raised when restoring ops to a channel. Essentially requiring a "leap of faith" on the part of the oper involved and left no room for accountability should the decision made in the end have been the wrong one. Further, there is precedent which shows that operator assistance in any of the above ways implies that we as a group of administrators and operators sanction the content of any of the channels which opers "interfere" with. This becomes undesirable when opers are asked to "fix" a channel such as #0daywarez or #sexpics (random examples) which potentially encourage the trading of illegal material. While opers could simply refuse to help these channels, a much simpler, cleaner, fairer solution can be managed. This proposed "channelfix" solution presents a quick fix to the oppless channel problem with a "services-like" server which does, on a constant basis, what the efnext "snapshot" mechanism does--cull a list of chanops, index it and build averages over periods of time. Rather than require server operators to be concerned with it, however, channelfix operates on the client layer with a "fixerbot" client which it uses to restore ops to channels which have become oppless. There are further potential uses for the channelfix server which are outside the scope of this document but include "repairing" TS0 channels, DCC functionality so admins and selected operators could "log in" to the service to watch chanfix's activities in realtime. FUNCTIONAL OVERVIEW: The channelfix server operates as a "services-like" server in that it links to the network but does not carry clients, or even have the ability to carry clients. It merely grabs the 8-10meg burst every 10-30 minutes, distills it to useful information and stores it in a database to be held for 3-10 days as a historical datagram of information which it will then self-reference when it detects that a channel has lost ops. Once fully functional, channelfix will join its "chanfix" client to the affected channel, compare the members of the channel to its stored list of people who have been opped in that channel and op the 5-most-frequent nicks (by userhost) and leave the channel, leaving it once again in a state of having ops. Here's a mock-up of what might happen: Pub: #fixtest stranged log @wjr *** #fixtest : End of /NAMES list. *** Mode change "-o wjr" on channel #fixtest by wjr *** chanfix (firstname.lastname@example.org) has joined channel #fixtest *** Mode change "+o chanfix" on channel #fixtest by chanfix.efnet *** Mode change "+oo wjr stranged" on channel #fixtest by chanfix.efnet *** chanfix (email@example.com) has left channel #fixtest Pub: #fixtest @stranged log @wjr *** #fixtest : End of /NAMES list. #fixtest stranged G@ ~firstname.lastname@example.org (0 *Unknown*) #fixtest log H* ~email@example.com (4 *Unknown*) #fixtest wjr H@ ~firstname.lastname@example.org (0 *Unknown*) As you can see, when wjr deopped himself, chanfix immediately saw it and remedied the situation. Since this channel was newly-created and wjr was the only one to ever have ops in the channel, log's userhost was not included in the op snapshot and thus log was not opped. TERMS AND LIMITATIONS: 1) The channelfix server will not be able to be used to restore ops to channels until it has been linked long enough to get enough samples to build averages. 3-5 days will be required for this. 2) The channelfix server will not operate when less than 7/8 of the "full network" is linked--in other words, if 6 servers are split, and oppless channels exist on the part of the net that the channelfix server is connected to, it will do nothing, until the servers rejoin. This is to avoid excessive "fixing" during periods of instability. It will also not update its "snapshot" database during such times. 3) The channelfix server will log all channels it fixes and who it opped. This information will be available (updated nightly) on a password-protected ssl webserver and made available to all admins. 4) The channelfix server will only track channels with 8 or more users in it on a "full net." Channels with 7 or less users will need to coordinate the re-creation of said channels on their own. This will cut down on the database size and the amount of "re-ops" performed by channelfix tremendously. 5) The channelfix server will only track non-dynamic, idented userhosts. A list of dynamic 'keywords' will be used to "weed out" hosts to ignore. This prevents Joe Dialup User from stealing John Dialup User's identity in order to take over a channel. 6) The channelfix server will have C/N lines to all hub servers with full H:. This allows it to connect anywhere in the event of a network outage due to attacks or natural catastrophe. DETAILED FUNCTIONAL SPECIFICATION: Awaiting coder input. Non-detailed spec should be sufficient for admins to make a determination whether or not this system is appropriate for use on EFnet or not.
