###  - capture the 'Word' and insert it into a larger URL containing an absolute reference to task view 'Word'

Server setup The first step is to install znc:

apt-get install znc

Make sure you get the 1.0 series (in jessie or trusty, not wheezy or precise) since it has much better multi-network support. Then, as a non-root user, generate a self-signed TLS certificate for it:

openssl req -x509 -sha256 -newkey rsa:2048 -keyout znc.pem -nodes -out znc.crt -days 365

and make sure you use something like irc.example.com as the subject name, that is the URL you will be connecting to from your IRC client. Then install the certificate in the right place:

mkdir ~/.znc
mv znc.pem ~/.znc/
cat znc.crt >> ~/.znc/znc.pem

Once that's done, you're ready to create a config file for znc using the znc --makeconf command, again as the same non-root user:

• create separate znc users if you have separate nicks on different networks
• use your nickserv password as the server password for each network
• enable ssl
• say no to the chansaver and nickserv plugins

Finally, open the IRC port (tcp port 6697 by default) in your firewall:

iptables -A INPUT -p tcp --dport 6697 -j ACCEPT

Client setup (irssi) On the client side, the official documentation covers a number of IRC clients, but the irssi page was quite sparse. Here's what I used for the two networks I connect to (irc.oftc.net and irc.mozilla.org):

servers = (
   
    address = "irc.example.com";
    chatnet = "OFTC";
    password = "fmarier/oftc:Passw0rd1!";
    port = "6697";
    use_ssl = "yes";
    ssl_verify = "yes";
    ssl_cafile = "~/.irssi/certs/znc.crt";
   ,
   
    address = "irc.example.com";
    chatnet = "Mozilla";
    password = "francois/mozilla:Passw0rd1!";
    port = "6697";
    use_ssl = "yes";
    ssl_verify = "yes";
    ssl_cafile = "~/.irssi/certs/znc.crt";
   
);

Of course, you'll need to copy your znc.crt file from the server into ~/.irssi/certs/znc.crt. Make sure that you're no longer authenticating with the nickserv from within irssi. That's znc's job now.

Wrapper scripts So far, this is a pretty standard znc+irssi setup. What makes it work with my workflow is the wrapper script I wrote to enable znc before starting irssi and then prompt to turn it off after exiting:

#!/bin/bash
ssh irc.example.com "pgrep znc   znc"
irssi
read -p "Terminate the bouncer? [y/N] " -n 1 -r
echo
if [[ $REPLY =~ ^[Yy]$ ]]
then
  ssh irc.example.com killall -sSIGINT znc
fi

Now, instead of typing irssi to start my IRC client, I use irc. If I'm exiting irssi before commuting or because I need to reboot for a kernel update, I keep the bouncer running. At the end of the day, I say yes to killing the bouncer. That way, I don't have a backlog to go through when I wake up the next day.

Missing: you can just hit Alt-F2 and enter the command

	in-target apt-get --purge -y install sysvinit-core
 

there, no need to preseed. But this does not eliminate the aforementioned shortcomings, of course.
