-Unless you are connecting from a datacenter //(see **"IRC in the Cloud"** below)// you will want to use a [[security:vpn|VPN]]. This is because on IRC //everyone can see your hostname and IP address//. So if you do not want people tracing back to your location, connect to IRC from a VPN, or from a remote server in the cloud.+Depending on how you are using IRC, you may not always need a [[security:vpn|VPN]]. If you are using TLS to connect to your favorite IRC servers, then your connection is already encrypted. If you are using IRC remotely //(see **"IRC in the Cloud"** below)// via SSH, then know SSH encrypts your connection as well. So rest assured, if you are hanging out with terrorists on EFNet, all anyone can really see is that you are connecting to EFNet - but they cannot see anything else unless this is happening in a public room on EFNet, which they would have to go find in a list of thousands of channels unless they have a way to man-in-the-middle a TLS connection. 
 + 
 +In many cases you will want to use a VPN. This is mainly because on IRC //everyone can see your hostname and IP address//. So if you do not want people tracing back to your location, connect to IRC from a VPN, or from a //via media// remote server in the cloud. 
 + 
 +You will also want a VPN if you are working sensitive [[:op:operations]] on a private IRC server. If you have a remote client in an opsec-conscious environment, you will want a VPN both ways: both between your local machine and your remote client, and between your remote client and the server. Even with encrypted connections using SSH and TLS, the datacenter can still pick up the IP addresses of everything your remote client talks to, and you cannot always trust the datacenter.

 +IRC was developed in a time before the prevalence of mobile phones & wireless internet connections. Because of this, it is a little frustrating to use on unstable connections. Furthermore, when you are disconnected and waiting to reconnect, you completely miss any messages that are being sent in your favorite channels.
 +
 +To get around this, you will want to set up an IRC client on a remote machine. For under $10/m, you can get a [[https://www.vultr.com/?ref=9732786-9J|Debian VPS with Vultr]] //(complete with automated backups)// on which you want to install [[tools:byobu]] or [[tools:tmux]], and a [[tools:bash|terminal-based]] IRC client like [[https://weechat.org/|WeeChat]] or [[https://irssi.org/|irssi]].
 +
 +By running an IRC client in this type of software stack, it will stay alive 24/7 even if you disconnect or close the window. When combined with a remote machine, you can use [[tools:ssh|SSH]] to check IRC at your leisure without missing a single message. You can even combine it with [[tools:wireguard|WireGuard]] to obfuscate the location of your VPS's datacenter from other IRC users.
 +
 +
 +===== Application Specific Instructions =====
 +
 +Here are some quick-start guides for several popular IRC clients, if you need help getting started.
 +
 +==== Configuring HexChat ====
 +
 +To point HexChat to our IRC, configure it as follows. (Click to enlarge)
 +

 +:tools:ss_1756624463.png Network List | Create entry for Hackint, favor and edit

 +
 +
 +
 +==== Configuring WeeChat ====
 +
 +Eventually you may need more functionality out of your IRC client, and when that time comes you will need a [[tools:bash|terminal]] client. WeeChat is probably the simplest of the terminal clients to configure. It also has a pretty robust out-of-the-box setup without having to track down plugins. For both these reasons, we recommend using WeeChat if you have never used a terminal-based client before.
 +
 +You can install WeeChat in Debian with the ''apt'' command, and then the ''weechat'' command to start it:
 +
 +  $ sudo apt install weechat
 +  $ weechat
 +
 +WeeChat requires a little bit of configuration to get going. First off, you will need to tell WeeChat to use Dynamic Rejoining. With this set, WeeChat will remember which channels you were in last, and automatically rejoin them when you connect:
 +
 +  /set irc.server_default.autojoin_dynamic on
 +
 +Next, you need to connect WeeChat to a server //(again, we will use Hackint as an example)//. To do this, you first need to define some details about the server:
 +
 +  /server add hackint irc.hackint.org/6697 -ssl -autoconnect
 +  
 +Then, use the ''/connect'' command to connect to Hackint:
 +
 +  /connect hackint
 +  
 +Once you are connected, you can type ''/join #ami'' to enter our IRC channel. To test that autoconnect works, type ''/quit'' to exit WeeChat. Then reopen WeeChat. It should dump you right back into #ami on Hackint. There is no real limit to how many servers/channels you can have WeeChat automatically join.
 +
 +To keep WeeChat alive on a remote machine, simply run it inside [[tools:byobu]] or [[tools:tmux]] via [[tools:ssh|SSH]]. Then just reattach to your session when you SSH back in.
 +
 +==== Configuring irssi ====
 +
 +Many power users prefer irssi as a terminal IRC client. Like WeeChat, it can be run locally, and on a remote machine via SSH.
