As another part of my basic setup, here is my irssi theme file:

default.theme.tar

And my precious key bindings, see this post to understand why it is from F7 to F10.

For this to work, just copy/paste this into your irssi:

The GNU Screen manual tells you that to use scrolling, you must first enter “Copy mode” with C-a [.

You can easily fix this and use regular PgUp/PgDn by simply adding a line to your ~/.screenrc. I really don’t know why this isn’t a default setting except that it seems to mess with Vim scrollback.

Here’s the line:

termcapinfo xterm ti@:te@

Enjoy.

Typically, from a single ssh connection comes a single shell, let’s improve this situation.

We will use a terminal multiplexor GNU Screen, which provide multiple terminals. We will also implement a neat tab bar to allow naming/showing tabs and automatic session re-attachment capability.

Follow these steps to significantly enhance your distant shell experience, you will need to install screen and ssh, mutt and irssi are optional.

The first step involves using environment variables in order to detect if the login is locally originating or not. If the user is logging from a distant machine, we will reattach an existing detached screen session or create a new one.

When logging in remotely, the most evident distinction i’ve found between a local and remote shell is the environment variable SSH_CONNECTION=, with this var we have a way of detecting remote logins easily and launch something else accordingly.

This is how i got my linux shell looking so wonderful, using GNU Screen of course and its famous ~/.screenrc configuration file.

Let’s create it and paste this into it:

#hardstatus string ” %wb%-w%wr%n %t%-%+w %=%D %d %M %y %c”
#hardstatus string “%r%c%k | %w% ? (%h)% ?”
#hardstatus string “%{gk}[ %{G}%H %{g}][%= %{wk}%?%-Lw%?%{r}(%{W}%n*%f %t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B} %m/%d %{W}%c %{g}]“
hardstatus string ‘%{= c}[ %{W}%H %{c}][%= %{= w}%?%-Lw%?%{c}(%{W}%n*%f%t%?(%u)%?%{c})%{w}%?%+Lw%?%?%= %{c}][%{W} %d/%m %{W}%c %{c}]‘

bindkey -k F1 prev
bindkey -k F2 next

screen -t irssi 1 irssi -c irc.freenode.net
screen -t mutt 2 mutt
screen -t monitor 0 lwatch -i /dev/xconsole

hardstatus alwaysignore hardstatus alwayslastline

The whole aesthetic thing reside in the first uncommented line, this is where it sets what is displayed in the hardstatus line which is always the last line. You can find documentation about the variables that can be used to display different types of information in the screen man page. ($ man screen).

As for the bindkey, you’ve guessed they bind keys to go forward and backward in your terminal tabs, and yes F1 means F11, don’t ask me why. I use F11 and F12 because i intend to use F9 and F10 in irssi to move between windows.

Gmail requires a secured connection for authentication and for this we need a certificate, here’s how:

Verify the current certificate gmail is using with this command:

openssl s_client -connect smtp.gmail.com:995 -showcerts

Hit Ctrl-c to terminate the command once you got something like this:

Here’s how to use postfix to send mail through gmail. Assuming you have postfix and libsasl2-modules installed, the rest should be automatically installed since it depends on it. First open your postfix main.cf file located at /etc/postfix/ (on debian).

Append this to the end:

relayhost= [smtp.gmail.com]:587
smtp_use_tls = yes
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous

smtp_destination_rate_delay = 60
relay_destination_rate_delay = 60

mailbox_command = /usr/bin/procmail -a $EXTENSION

My home file server used to be headless, but i thought it deserves a head even if it’s only a PIII 300mhz/256mb of ram, no video accel. So i installed a minimal Xorg server with openbox as a window manager. Then i remembered, maybe 10 years ago when i was using WindowMaker and/or Blackbox i had to fiddle with xmodmaps and xkeycaps to get french accents working. Now i realize there is a much more simpler way to do it through the Xorg config file /etc/X11/xorg.conf.

Section “InputDevice” Identifier “keyboard”
Option “XkbRules” “xorg”
Option “XkbLayout” “ca”
Option “XkbVariant” “fr”
EndSection

Just modify your keyboard section with the above Xkb options.

And there you are, with a french canadian keyboard layout! Now i can watch pictures with french accents in the filename…
