Working with IRSSI and Screen
Irssi is a command line IRC client, GNU screen is an application that keeps your programs running even when you're not logged in. Combined with SSH, this means that you'll never have to be disconnected from IRC again :)
On linux or MacOS you can simply open a terminal (Applications -> Utilities -> Terminal in MacOS).
On Windows you can install PuTTY, a ssh client.
To start, SSH to your box.
Starting Screen, some basic screen commands
To start screen for the first time, just type: screen
To resume a previous screen session, just type: screen -raAd (r-resume aA- some resizing d- detatch any remote sessions you may have left open elsewhere)
- Important:* do not start multiple screens, this will just lead to insane confusion and (possibly) overuse of system resources
Your screen session behaves exactly like a normal linux TTY, except you can detach it and reattach it from anywhere, meaning anything you may be doing will not be killed when you disconnect from SSH, this is ideal for IRC ;)
Some screen commands:
Ctrl-a-d: detaches your screen
Ctrl-a-c: creates a new window within your screen
Ctrl-a-<number>: switches to a different window within your screen
Ctrl-a-a: switches back to the previous window you were viewing
Ctrl-a-n: switches to the next window
Ctrl-a-p: switches to the previous window
Starting irssi
Irssi is a command line only IRC client, it is ideally suited for ssh shells.
To start irssi:
irssi
This will automatically connect you to the BySH IRC server, and you can start chatting instantly :)
Window 1 is the status window, this will show notices, ctcps, whoises and connection stuff (like motds) The activity alert shows you what has happened: if it's blue, someone has joined/parted/quit/changed nick if it's white, someone has said something if it's red, someone has said your nick
Some irssi commands
PageUp: scrolls up
PageDown: scrolls down
Ctrl-n: moves to the next window
Ctrl-p: moves to the previous window
Alt-<number>: jumps to window no. <number>
/wc: closes the current window
/connect irc.server.net: connects to a different IRC server, without closing current connections
/n: list users in the current channel
Some irssi configuration options
Show seconds in time stamps:
/set timestamp_format %H:%M:%S
Change the highlight colour:
/set hilight_color %colourcode
%k black %K dark grey %r red %R bold red %g green %G bold green %y yellow %Y bold yellow %b blue %B bold blue %m magenta %M bold magenta %p magenta (think: purple) %c cyan %C bold cyan %w white %W bold white
Change the activity alert colour for highlights:
/set hilight_act_color %colourcode
Configuring auto-connect to networks, channels and auto-identifying to NickServ
To set up autoconnection to IRC network: irc.example.net on port 6667 (default for most IRC servers), auto-joining channel: #channel and identifying to NickServ when connected.
/NETWORK ADD -autosendcmd "/^msg NickServ IDENTIFY PASSWORD;wait 2000" ExampleNetwork
/SERVER ADD -auto -network ExampleNetwork irc.example.net 6667
/CHANNEL ADD -auto #channel ExampleNetwork
screen_away:http://scripts.irssi.org/scripts/screen_away.pl this automatically sets your status to away when you detach your screen
active_notice:http://scripts.irssi.org/scripts/active_notice.pl prints notices in the window you are currently viewing rather than the status window
trackbar:http://scripts.irssi.org/scripts/trackbar.pl shows a line where you last read a channel
adv_windowlist:http://anti.teamidiot.de/static/nei/*/Code/Irssi/adv_windowlist.pl see later for description
autorejoin:http://scripts.irssi.org/scripts/autorejoin.pl auto rejoins you when kicked
to install a script, place it in ~/.irssi/scripts/
this may need to be created if it doesn't already exist
[email protected]:~$ cd ~/.irssi
[email protected]:~$ mkdir scripts
[email protected]:~$ cd scripts
[email protected]:~$ wget URL_of_script
to load the script in irssi, type:
/script load scriptname.pl
to autoload scripts when you start up irssi (not that you'll ever have to stop irssi ;))
symlink them in ~/.irssi/scripts/autorun
[email protected]:~$ cd ~/.irssi/scripts
[email protected]:~$ mkdir autorun
[email protected]:~$ cd autorun
[email protected]:~$ ln -s ../scriptname.pl .
Advanced Windowlist
Remove the standard activity notice element, advanced windowlist gives you a much better way to deal with the same thing :)
/statusbar window remove act
you may need to play around with /statusbar to get everything exactly to your liking
Highlight notifications on your local machine _This has only been tested on Linux + Gnome_ _It will definitely not work on windows_
"fnotify":http://www.leemhuis.info/files/fnotify/fnotify is a script that writes highlights into ~/.irssi/fnotify
save this in ~/.irssi/scripts/, symlink it in autorun and load it in irssi (See above).
notify-send is a linux command that sends notifications to your desktop environment, you can test that it is working/installed by typing: notify-send test into a terminal. If it doesn't work, you need to google around for how to enable notify-send on your box.
If it does work, you can then write a bash script on your local machine that will check this file for new highlights (using the tail command)
Paste this "code":http://www.burn-blue.com/paste/view/aGt5K8To into ~/irssi_notify.sh on your local machine, editing the connection info appropriately
then in a terminal, type:
cd
chmod 755 irssi_notify.sh
./irssi_notify.sh
You will now get nice notifications :)
Putty copy and paste Just highlight the text you want to copy with the cursor and it will be copied to the clipboard If you want to paste into putty, just right click
