anyway, your best bet is measuring your own lag only and take your chances from there

yea guess you're right, i don't think there's any script that does this, so doing it this alone is a good improvement.
thanks for the help, this was kinda fun hehe

that's why implementing anything beyond pinging your own server is simply not viable, it would become too complex with too many factors to account for

besides, you can't know what server joining users are on, so you can't really implement such a system, even if you are certain about the algorithm

however, a pure network-wide lag tracking system (one that is not coupled with protection scripts) could be implemented; in fact, it has been implemented already, at least in one instance: there was a bot on EFnet's #netsplit years ago that was announcing to the channel which server is about to split from which, and all takeover monkeys would race to that server in a bid to get ops and fight with rejoining op parties thereafter

anyway, your best bet is measuring your own lag only and take your chances from there

mmm i guess am taking the lag effect from 1 side: that the lagging server will RECEIVE the joins suddenly, and not SEND them suddenly.

anyways in this case , it would be to complex to let the bot know everything and decide, lol trying to figure all this out might even make it lag hehe

you don't care about server3? what if your users are on server3 or/and servers behind it and it's server3 that sends all those legitimate JOINs at once, tricking you in locking the chan?

lol

i think each on is taking the word lagging differently.

am not checking whether server2 and server3 are lagging
let's take this:

i am the bot
i pinged my own server and i got a 0.01 sec reply no lag to my own server, my connection is fine...

i ping server2 and server3
i found that the reply is 0.02 and 0.01 everything seems to be normal, the server am connected to is not lagging relatively to the other servers

i ping server2 and server3
i got replies : 3.21 and 4.32 most probably the server am connected to is lagging , since both server2 and 3 had big reply time

i ping server2 and server3
i got replies: 0.02 and 4.32 i can't assume that my server is lagging, because of the reply from server2 is 0.02 , it could be that server3 is the one lagging, but i don't care about it

i hope am not confusing you

so we are back to my previous post about complex lag tracking system and zillions scenarios

lagging to what? to the bot? then what does [ping server2] means in your pseudo-code?

i want to check if the bot is lagging to server2 (in case it's not lagging to server1, it's own server)
if the bot is not lagging to it's server
and the bot is lagging to server2 and server3
then this most porbably means that server1 is lagging to other servers.

b-

3 means pinging other servers

yes i want to ping other servers to accomplish a

anyways for now i'll settle for what's done and test it. the case of the lagging server can wait lol

i thought about parsing LINKS(to get the list of servers) and WHOIS (to know where the bot is connected)

there is global variable server, don't go with whois'ing self

what am actually checking if the server that the bot IS connected to is lagging or not. not other servers
because if it is then it could cause probs.

lagging to what? to the bot? then what does [ping server2] means in your pseudo-code?

and also is not about splits/rejoins
it's about to know forexample : if the bot noticed 6 joins happened in 3 seconds it could be due to 3 possible reasons:
1- the is actually a flood
2- the bot it self is lagging
3- the server on which the bot is connected is lagging and suddenly received the packets and displayed them.

1 and 2 are taken care of, 3 remain to be completed.

hopefuly this clears up my thought more

3 means pinging other servers

hmm so you are proposing a complex lag tracking system but you are not elaborating on details

obviously, you'll need to know the structure of the network, i.e. which servers your server connects to (that can be obtained by analyzing LINKS output); and you will have to come up with some algorithm for taking the ultimate decision whether to take action or not; however, that won't be easy since there can be all kind of scenarios; consider for example:

you are on server A, which connects to B, C and D; you have pinged B, C and D and detected no lag; however, D connects to E, and D is lagging to E, and most of your users are either on E or on servers behind E; so E splits, rejoins, and you take action because your averaged lag measurement for the neighbouring servers didn't go above the trhreshold

if the ping reply is greater than 3 seconds then the bot is lagging due to it's connection or load on box or whatever.
in case it's not, we should also check if the IRC server is lagging (is about to split or something)

pinging other servers is pointless since if you are lagged to your own server, you'll be lagged to all others anyway - you have only one connection to IRC in any given moment, and that connection is through the server you are on

Code:

proc lag_check {} {global laggingset lag0 [ping server1]if {$lag0 > 3 } { set lagging 1 return}# server1 != server2 != server3set lag1 [ping server2]set lag2 [ping server3]if {$lag1 > 3 && lag2 > 3 } {set lagging 1return}}

explanation of pseudo code: (EDIT*: it's not really pseudo code, it's more like code hehe)
server1 = the server to which the bot is connected.
if the ping reply is greater than 3 seconds then the bot is lagging due to it's connection or load on box or whatever.
in case it's not, we should also check if the IRC server is lagging (is about to split or something)
so we ping 2 other servers , server2 and server3
if the reply of both is greater than 3 seconds then server1 is lagging
and thus the bot is considered lagging and shouldn't issue commands

what do you guys think about this?

what's needed is:

a function that pings the server and returns the reply
to get the 2 other server names to ping.

i know it's should be in the scripting forum but it's about the pervious.

but what will you do if you notice the bot has lagged 60s and somone triggers a 10s flood? do you want to ignore the flood? it might have been really a flood, it might have not been. How will you determine?

i have more than 1 bot protecting the channel, so if one bot is lagging
i will rely on the others.

and I will probably have periodic lag checks; on mass flood, I won't issue any server commands if the average lag from previous minute or so has been unacceptable

that seems to be a good idea, to rely on an average lag time

you get the lag not by parsing .status but by pinging the server and measuring its response time
