[Bug 332521] [NEW] [jaunty] no internet connection: dhclient-script cannot be execve'd

[Matteo Settenvini]

Public bug reported:

Description:	Ubuntu jaunty (development branch)
Release:	9.04
Linux Dahlia 2.6.27-1-powerpc64-smp #1 SMP Fri Nov 7 02:34:19 UTC 2008 ppc64 GNU/Linux

After today updates, I find myself unable to have dhcp working (thus,
also networkmanager doesn't work).

If I run manually "dchlient eth1", I get:

root at Dahlia:/var/cache/apt/archives# dhclient eth1
There is already a pid file /var/run/dhclient.pid with pid 9119
killed old client process, removed PID file

execve (/sbin/dhclient-script, ...): Permission denied
Listening on LPF/eth1/00:11:24:70:fe:6e
Sending on   LPF/eth1/00:11:24:70:fe:6e
Sending on   Socket/fallback
DHCPREQUEST of 192.168.1.215 on eth1 to 255.255.255.255 port 67
DHCPACK of 192.168.1.215 from 192.168.1.1
execve (/sbin/dhclient-script, ...): Permission denied
bound to 192.168.1.215 -- renewal in 9772 seconds.

So, I tried running manually dhclient-script as root:

root at Dahlia:~# /sbin/dhclient-script 
bash: /sbin/dhclient-script: /bin/bash: bad interpreter: Permission denied

However:

root at Dahlia:~# ls -l /sbin/dhclient-script 
-rwxr-xr-x 1 root root 8714 2009-02-19 18:50 /sbin/dhclient-script

and:

root at Dahlia:~# head -n 1 /sbin/dhclient-script 
#!/bin/bash
root at Dahlia:~# ls -l /bin/bash
-rwxr-xr-x 1 root root 842096 2008-05-12 20:49 /bin/bash

WTF is going on???
