So this is an UnrealIRCd with default settings? No changes to config.h/struct.h? I can't reproduce it with 'azertyuiopqsdfghjklmwxcvbnazer' on my ircd. Does it also occur with a different 30 character nick? |
|
|
Also, any source modifications? Any 3rd party modules? |
|
|
Yes, default settings, no patch applied, no 3rd party modules. Same bug occurs with the nickname "iiiiiiiiiiiiiiiiiiiiiiiiiiiiii" and we doesn't use the "set::nick-length" configuration. Links are configured as "insecure" : link ircdev02.prodin.orbus.fr { outgoing { hostname 172.18.104.193; port 6667; options { autoconnect; insecure; }; }; incoming { mask 172.18.104.193; }; password "*"; hub *; class servers; }; I can send you our unrealircd.conf in private if it can help you ^^ |
|
|
Strange. Yes, could you send your entire unrealircd.conf from both servers to [email protected] ? Best to ***** out the passwords, even for me :) |
|
|
Done ;) |
|
|
Thanks, I was going to email you that I cannot reproduce. But now I just reproduced the problem and saw the kill. I'll look into this now :) |
|
|
Could you keep the issue quiet while I trace this? I'm not sure if it has security impact (yet) :) |
|
|
OK ! Thx ;) |

Fixed in 4.0.9, released yesterday. Thanks again for informing us about this bug :) https://github.com/unrealircd/unrealircd/commit/a3cdb49bc94388e5d918777b8f61b528aff4e69a |
