====== Update UnrealIRCD ======

===== Introduction =====

Installing / updating UnrealIRCD (tested with version 6.1.0)

===== Importing GPG keys =====

<code bash>
wget -O- https://raw.githubusercontent.com/unrealircd/unrealircd/unreal60_dev/doc/KEYS|gpg --import
</code>

===== Download source =====

First we download the source files. The current version is replaced instead of x.x.x (e.g. unrealircd-6.1.0.tar.gz).

<code bash>
wget https://www.unrealircd.org/downloads/unrealircd-x.x.x.tar.gz
</code>

===== Check integrity =====

<code bash>
wget https://www.unrealircd.org/downloads/unrealircd-x.x.x.tar.gz.asc
gpg --verify unrealircd-x.x.x.tar.gz.asc unrealircd-x.x.x.tar.gz
</code>

===== Unpack archive =====

Now we unpack the archive.

<code bash>
tar xfvz unrealx.x.x.tar.gz
</code>

===== Stop / rename old IRCD =====

To protect the config files, the directory with the obsolete IRCD should be renamed. To do this, the UnrealIRCD must first be stopped.

<code bash>
./Unreal.x.x.x/unreal stop
mv Unrealx.x.x Unreal
</code>

===== Configuring the sources =====

Let's change to the directory of the new IRCD and start with the configuration.

<code bash>
cd Unrealx.x.x
./Config
</code>

Now the configuration process begins. The following values are recommended:

<code bash>
In what directory do you want to install UnrealIRCd?
(Note: UnrealIRCd 6 will need to be installed somewhere.
 If this directory does not exist it will be created.)
[/home/USER/unrealircd] ->

What should the default permissions for your configuration files be? (Set this to 0 to disable)
It is strongly recommended that you use 0600 to prevent unwanted reading of the file
[0600] ->

If you want, you can manually enter the path to OpenSSL/LibreSSL here.
In most cases you can leave this blank and it will be detected automatically.
[] ->

UnrealIRCd comes with support for 'remote includes', this allows things like:
include "https://www.example.org/files/opers.conf";
Do you want to compile with the libcurl library to enable additional protocols?
If you answer 'No' then only https:// links will work for remote includes.
Answer 'Yes' if you need other protocols, such as plaintext http, ftp, tftp or smb.
Most people answer 'No' here because they don't use remote includes or only need https.
[No] ->

How far back do you want to keep the nickname history?
[2000] ->

GeoIP is a feature that allows converting an IP address to a location (country)
Possible build options:
     classic: This is the DEFAULT geoip engine. It should work on all systems
              and receives automatic updates.
libmaxminddb: This uses the libmaxminddb library. If you want to use this, then
              you need to install the libmaxminddb library on your system first
        none: Don't build with any geoip library (geoip-csv is still built)
Choose one of: classic, libmaxminddb, none
[classic] ->

What is the maximum number of sockets (and file descriptors) that
UnrealIRCd may use?
It is recommended to leave this at the default setting 'auto',
which at present results in a limit of up to 16384, depending on
the system. When you boot UnrealIRCd later you will always see
the effective limit.
[auto] ->

Are you running UnrealIRCd as a test, debugging a problem or developing a module?
Then it is possible to run with AddressSanitizer enabled. This will make it
catch bugs such as out-of-bounds and other memory corruption issues, which can
be really helpful in some cases. The downside is that it will consume a lot
more memory and run slower too. So, only answer 'Yes' if you are OK with this.
Also, on some systems (notably FreeBSD), when you enable AddressSanitizer,
UnrealIRCd may fail to start. So when in doubt, answer 'No'.
Do you want to enable AddressSanitizer?
[No] ->

Would you like to pass any custom parameters to configure?
Most people don't need this and can just press ENTER.
Otherwise, see `./configure --help' and write them here:

==== TLS parameters ====

The details can be set as required.

===== Compiling the sources =====

Now we compile the sources.

===== For a new installation =====

<code bash>
make install
</code>

The config files must then be edited.

===== For update =====

===== Copy the config files =====

FIXME This section still refers to version 3

The following files must be copied from the old directory to the new one:

<code text>
ircd.motd
ircd.rules
oper.conf
server.cert.pem
server.key.pem
server.req.pem
spamfilter.conf
unrealircd.conf
vhost.conf
network/yournetwork.network
</code>

===== Start Unreal =====

Now we can start the IRCD.

<code bash>
./unrealircd start
</code>
