DHCPv6 client with support for link-layer address DUID

WoW, latest version of Dibbler DHCPv6 client supports Link layer addressed based DUID, which means now server can advertise client specific stuff more easily, like assigning them static IPv6 addresses. So, time for setting up an IPv6 network using DHCPv6 :)

My first vim hack: syntax file for Coco/R

Few days back I hacked a vim syntax file for Coco/R. It is available under Vim license. Download it from http://wahjava.googlepages.com/coco.vim . To install it, see Installing a syntax file, and filetype page.

If you’re feeling lazy, looking for simple steps:

[abbe@chatteau ~] mkdir -p ~/.vim/syntax && wget -P ~/.vim/syntax http://wahjava.googlepages.com/coco.vim
[abbe@chatteau ~] cat >~/.vim/filetype.vim <<EOF
" my filetype file
if exists("did_load_filetypes")
    finish
endif
augroup filetypedetect
    au! BufRead,BufNewFile *.atg    setfiletype coco
augroup END
EOF

NOTE: Above steps, might alter your existing vim setup, so better read the vim manual :-P. Anyways, happy viming… :-)

Wanna run a nested X server

Running a nested X server Xephyr in Fedora 7 is so easy. Follow the following steps:

1. Install xorg-x11-server-Xephyr package from Fedora repositories using yum install xorg-x11-server-Xephyr command
2. Start 2 instances of terminal (e.g. xterm) in already running X server.
3. In 1st instance of terminal, execute xwininfo |fgrep "Window id".
4. Now with the crosshair cursor, select 2nd instance of the terminal.
5. Note on the window id which prints on the 1st terminal. e.g. 0x4c00022 is the Window ID from following output:
   xwininfo: Window id: 0x4c00022 "wahjava@chatteau:~"
6. Now in 1st instance of terminal, execute Xephyr -parent 0x4c00022 -ac :1 &.
7. Now to run gedit in new Xephyr X server, execute following in 1st instance of terminal:

   [wahjava@chatteau ~]$ DISPLAY=:1 metacity&
   [5] 6365
   [wahjava@chatteau ~]$ DISPLAY=:1 gedit&
   [6] 6366

8. So if there is anything you wanted to execute in this Xephyr X server, you’ve to make sure that you’ve DISPLAY=:1 environment variable set.
9. When done playing with your Xephyr X server, do killall Xephyr.
10. Back in 2nd terminal instance :)

Some screenshots:

This might not be a recommended way to run Xephyr. So don’t complain, anyways Happy Xephyring… :-D
