The network does not start anymore and I do not know what is wrong, it is not selinux blocking it, because the fix does not work :(, there might be something wrong with the original network scripts :(, booting hanged, I had to boot into level 1 and chkconfig network off, in order to boot :(

[root localhost ~]# rpm -qa initscripts*
initscripts-8.89-1.i386                 
You have new mail in /var/spool/mail/root
[root localhost ~]# service network status
Configured devices:
lo eth0 eth1
Currently active devices:
lo
[root localhost ~]# service network restart
Shutting down loopback interface:                          [  OK  ]
Disabling IPv4 packet forwarding:  net.ipv4.ip_forward = 0
                                                           [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:
Determining IP information for eth0...^C
[root localhost ~]# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 10.128.0.4
nameserver 10.154.16.130
nameserver 10.128.0.129
[root localhost ~]# ifconfig eth0 10.154.19.210 netmask 255.255.255.0
[root localhost ~]# route add default gateway 10.154.19.1

The other two machines use NetworkManager and there are no problems to report there :)

There is something wrong should I open a bugreport, unless someone has beated me to it :)

Regards,

Antonio
