0006604: ~msgbypass:censor does not work on ~text:censor bans

Thu, 15 Jan 2026 08:21:43 +0100

A ~msgbypass:censor exemption does not work on ~text:censor bans, as it may be expected.

0006486: UnrealIRCd Windows binaries have incorrect PE header when built from source

Fri, 06 Dec 2024 08:37:54 +0100

this only affects builds from source.
i am using a extension for the version tab but basically details tab also shows there's a issue as well.
CompanyName is none for some reason as well.
regression

0006439: two listen blocks with same port

Sat, 20 Jul 2024 08:39:10 +0200

Someone reported that you could (accidentally) add a second listen block and reported it crashed the server (on Windows). I add it on *NIX and it doesn't crash but no error/warning either. Both are bugs, presumably needing the same resolution.

0006326: Provide more information on Permission denied for oper privileges

Tue, 15 Aug 2023 10:45:43 +0200

So, for some reason my bot receives this at login.
But I have no idea why!

:Permission Denied- You do not have the correct IRC operator privileges

0004687: Linking to server by hostname: try IPv4 address first and then IPv6

Sun, 19 Mar 2023 11:40:48 +0100

Ideally, when connecting to a server by hostname with both an IPv4 and IPv6 record then UnrealIRCd should try IPv6 first and then IPv4. Right now it tries IPv6 and then if that fails, it gives up.
To workaround it currently you have to force IPv4 either by specifying an IPv4 link::bind-ip or setting an IP explicitly in link::outgoing::hostname.

Of course this "only" matters if the IRCd is IPv6-capable (like many) but the host is not truely connected to an IPv6 network (very common as well) and the remote host has an IPv6 address (right now.. not so common).

0005465: run scripts through shellcheck

Sat, 28 May 2022 16:29:52 +0200

Apparently there is https://www.shellcheck.net/ to check shell scripts
Run ours through those... who knows if it catches something.

0005949: ERR_NOSUCHNICK should not be sent as a reply to NOTICE

Sat, 03 Jul 2021 09:37:33 +0200

This is a bit of a controversial issue, but:

"automatic replies must never be
sent in response to a NOTICE message. This rule applies to servers
too - they must not send any error reply back to the client on
receipt of a notice"
<https://tools.ietf.org/html/rfc1459#section-4.4.2>

'automatic replies MUST NEVER be sent in response to a NOTICE message.
This rule applies to servers too - they MUST NOT send any error repl
back to the client on receipt of a notice."
<https://tools.ietf.org/html/rfc2812#section-3.3.2>

and Unreal does not follow this

0005926: Remote pings come back without the label message-tag

Fri, 25 Jun 2021 19:59:39 +0200

To reproduce:

CAP REQ :message-tags labeled-response batch
// This comes out OK, but it's not a remote ping. It's the local server replying
@label=zzz PING irc.goat.chat
@label=zzz;msgid=3J25TFrS7JaQ33NpuF7e3q;time=2021-06-25T17:44:40.071Z :irc.shitposting.space PONG irc.shitposting.space irc.goat.chat

// This is an actual remote ping but it comes back without the label!
@label=zzz PING * irc.goat.chat
@msgid=tkHnKAoWS5UtO9Erx8Tj5N;time=2021-06-25T17:44:43.287Z :irc.goat.chat PONG irc.goat.chat foo

0003917: set::modes-on-oper doesn't support negative/removing modes

Fri, 18 Sep 2020 20:52:40 +0200

hello,

for set::modes-on-oper the combination of adding AND removing several usermodes doesn't work.

0005643: Moddata serialize function is called for modules that failed to load

Sat, 27 Jun 2020 13:09:58 +0200

A module can request request client moddata with sync enabled and provided serialize and unserialize functions inside the MOD_INIT call. If the later MOD_LOAD fails, the moddata remains registered, resulting in a crash during server linking when unavailable code for serialize function is called.

0005474: Prod translators to update helpop etc

Wed, 15 Apr 2020 09:02:00 +0200

But before we do, probably have a look at helpop yourself first, eg the tables. Only a quick look though.

0005202: Remote rehash -ssl gives no output

Wed, 04 Dec 2019 08:32:51 +0100

The command "/rehash remoteserver.example.com -ssl" causes no reply. I would expect something, just like with a regular rehash.

0005467: Windows: Crash on "About UnrealIRCd"; GUI option disabled for now

Mon, 18 Nov 2019 14:36:40 +0100

In the Windows GUI version of UnrealIRCd, if you click on "About UnrealIRCd" it will crash. This is since the 32 bit to 64 bit conversion.
I've temporarily disabled the 3 gui options so you get an empty dialog for now. Let's take a look at this later... not really important for end-users anyway.

0005091: no bind/config errors in GUI?

Fri, 07 Sep 2018 10:30:34 +0200

Some quick note / impression on some system:
Had something else listening on an ircd port, then fired up UnrealIRCd GUI version. It did not complain at all in the GUI and showed the normal status screen even though it couldn't bind to the port.
Makes you wonder what else isn't shown...

0004923: admin block required even with m_admin disabled.

Tue, 04 Apr 2017 07:25:38 +0200

If you choose not to load the m_admin module in modules.conf, the admin{} block is still required as it throws the following error on rehash:

*** Loading IRCd configuration..
*** error: admin {} block is missing
*** error: 1 errors encountered
** error: IRCd configuration failed to pass testing

0004694: Windows file editor: support for colors is broken

Sat, 04 Jun 2016 19:27:21 +0200

The Windows GUI has a config/MOTD editor which has support for foreground/background colors, but this is broken. It produces incorrect output.
(Also a crash was reported which had possibly something to do with this as well, not sure)

Not terribly important, but it's an issue..

I've never touched this code, it looks rather ugly too.

0004043: Caution about mismatched cloak-keys should also apply to hiddenhost-prefix ?

Sun, 26 Feb 2012 21:42:44 +0100

http://www.unrealircd.com/files/docs/unreal32docs.html#setblock cautions that cloak-keys must be the same on all linked servers. It seems to me that the same caution also ought to apply to hiddenhost-prefix?

Ideally the ircd would also check for mismatches at link time in much the same way cloak keys are checked.

0002308: Virus Help Channel Suggestion

Sun, 10 Jun 2007 18:51:30 +0200

I was playing around with the virus help channel spamfilters, and I noticed that it had been done quite well.

Unfortunatly, I have noticed that with mIRC, if the channel window is closed, all the client gets is "PART Unknown command". After that, the client has no way to re-open the channel window to get the help it needs.

Because of this, I am suggesting another option for the spamfilter which will detect a PART sent from the client and respond with a JOIN. This can either be an option, such as set::spamfilter::virus-help-channel-force-rejoin, or can be hard-coded behavior of Unreal.

For those who do not understand, there is an example in Additional Info.

0002261: Alias block documentation

Fri, 27 Apr 2007 12:52:38 +0200

The docs need a little more information about using channels. Nothing is mentioned about channel modes affecting messages, and there is also nothing mentioned about needing to be out of the target channel in order to use the alias.
