How to launch VNC with aMule at Linux boot
By Frankk
This describes a very simple configuration to launch VNC at Linux startup (as a specified user). aMule will be launched automatically with VNC. This will work in Slackware and distro based on the same init method. If someone knows how to modify it to make it work under other distros you are welcome to add it to this page. Thanks.
Add the rc.vnc script to /etc/rc.d
Modify user according to the user running aMule.
The rm /tmp/.X11-unix/X$theScreen is there in case the server crashes or your mother/wife removes the power plug cleaning the room... ;-)
#!/bin/sh # # Startup/Stop script for vncserver. # #Here, the choosen user to run amule theUser=choosenuser #And here, the choosen screen to run the vncserver theScreen=1 case "$1" in 'start') if [ -f /tmp/.X11-unix/X$theScreen ]; then rm /tmp/.X11-unix/X$theScreen; fi /bin/su - $theUser -c "PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin /usr/bin/vncserver :$theScreen" ;; 'stop') /bin/su - $theUser -c "PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin /usr/bin/vncserver -kill :$theScreen" ;; *) echo "Usage: /etc/init.d/rc.vnc { start | stop }" ;; esac
Make it executable with:
chmod 755 /etc/rc.d/rc.vnc
Modify the following files:
In /etc/rc.d/rc.local add:
# Start VNC server if [ -x /etc/rc.d/rc.vnc ]; then . /etc/rc.d/rc.vnc start fi
In /etc/rc.d/rc.6 add:
# Shut down the VNC server if [ -x /etc/rc.d/rc.vnc ]; then /etc/rc.d/rc.vnc stop fi
In ~/.vnc/xstartup (in home directory of the user specified above) add (change with your preferred aMule startup script):
amule &
On Debian Woody
Run (as root):
apt-get install vncserver xvncviewer apt-get install vncserver flwm
There is no support for ~/.vnc/xstartup so, instead, use $vncStartup in .vncrc to determine a xstartup-script (this replaces your ~/.xsession file).
For more information, read man vnc.conf
For example, in a Woody/Sarge/Sid:
Login as the user who is going to run aMule
mkdir ~/.vnc/
Create the ~/.vnc/xstartup file, with the next content
/usr/bin/flwm & /usr/bin/amule & /usr/bin/amule &
With sone versions of vncserver, it's necessary to launch at least twice the aMule. The flwm is an optional window manager.
Create the file ~/.vncrc with the next content:
Login as the user and run xvncviewer :1 to create the password file and debug possible probelms (the logs are under the ~/.vnc/ dir
$vncStartup = "/home/amule/.vnc/xstartup"; $geometry ="800x600";
(replace /home/amule for the home of the user running VNC)
To show the aMule window, run:
xvncviewer localhost:1
Mandrake 10.0
The script from Frankk is the one I use, but you can customize the size of the VNC server :
/bin/su - $theUser -c "PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin /usr/bin/vncserver :$theScreen"
add
/bin/su - $theUser -c "PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin /usr/bin/vncserver :$theScreen -geometry 1240x980"
or whatever value.
Personaly, I use as xstartup script (iceWM is really nice and so CPU-cheap) :
#!/bin/sh starticewm& amule
To start VNC at startup, I called the previous script /etc/init.d/amulevnc and chmod to 744 (chmod 744 /etc/init.d/amulevnc as root).
Instead of modifying /etc/rc.d/rc.vnc, I added links in the corresponding /etc/rc$RUNLEVEL.d directories.
It's quite simple to understand how it works:
Each directory represents a runlevel, and contains links to the scripts from /etc/init.d which need to be run/stop.
For instance, the link /etc/rc5.d/S55sshd to /etc/init.d/sshd will start sshd on runlevel 5,
whereas /etc/rc6.d/K25sshd linked to /etc/init.d/sshd will stop it in runlevel 6.
You get it? Links starting with 'KXX' will stop a service, and those starting with 'SXX' will start them. The number will define the order.
So to run VNC on startup, just do (as root :-) )
ln -s /etc/init.d/amulevnc /etc/rc5.d/S99amule ln -s /etc/init.d/amulevnc /etc/rc6.d/K02amule
and you're all set!
PS: This method should work on systems other than Mandrake, give it a test.
