rehash errors such as error: set::geoip-classic::ipv6-database: cannot open file "/home/xxxx/unrealircd/data/https://www.unrealircd... and possibly even a crash. The initial boot of UnrealIRCd, however, was always fine, this only happened when rehashing. It also seemed to occur more with ftp:// includes or at least with multiple parallel includes, that may or may not have different or more latency. In any case it seemed to affect some remote includes setups semi-consistently, and others not at all. The root cause was a complex code path causing a read-after-free. We now use a simplified code path which can no longer cause this. The only downside is that rehashing may be delayed up to an extra 250ms (quarter of a second), but that should hardly be noticeable, if at all. Issue reported by Bun-Bun.

How to get started
Please consult our excellent online documentation at https://www.unrealircd.org/docs/ when setting up the IRCd!
Step 1: Installation
Windows
Simply download the UnrealIRCd Windows version from www.unrealircd.org
Alternatively you can compile UnrealIRCd for Windows yourself. However this is not straightforward and thus not recommended.
*BSD/Linux/macOS
Do the following steps under a separate account for running UnrealIRCd, do NOT compile or run as root.
Step 1: Compile the IRCd
- Run
./Config - Run
make - Run
make install - Now change to the directory where you installed UnrealIRCd, e.g.
cd /home/xxxx/unrealircd
Step 2: Configuration
Configuration files are stored in the conf/ folder by default (eg: /home/xxxx/unrealircd/conf)
Create a configuration file
If you are new, then you need to create your own configuration file: Copy conf/examples/example.conf to conf/ and call it unrealircd.conf. Then open it in an editor and carefully modify it using the documentation and FAQ as a guide (see below).
Step 3: Booting
Linux/*BSD/macOS
Run ./unrealircd start in the directory where you installed UnrealIRCd.
Windows
Start -> All Programs -> UnrealIRCd -> UnrealIRCd
