Network problem in SL 6.6
Hi all,
I downloaded Scientific Linux 6.6, but it didn't connect to internet.
There is a wrong sign on the "internet icon" on the start up bar and
when I click on this icon i find the wired connection closed (I can't click on), also the cable connected to the laptop dose not flash.
When I enter > system > network connections, I find wired system eth0 connection, in which the MAC address set to 00:00:00:00:00:00, while "Apply" icon is not activated
Here is the output of $ifconfig
lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:40 errors:0 dropped:0 overruns:0 frame:0 TX packets:40 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2880 (2.8 KiB) TX bytes:2880 (2.8 KiB)

Here is the output of $ifconfig eth0

The eth0 cofiguration file on /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
UUID=48b4edd8-26a9-427e-abad-b4acac8e42ee
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
HWADDR=52:54:00:EE:44:CD
PEERDNS=yes
PEERROUTES=yes
And when I type ifup eth0
[root@localhost network-scripts]# ifup eth0
Error: No suitable device found: no device found for connection 'System eth0'
Note that when I change the MAC address on
system> network connections > system eth0 to : 52:54:00:EE:44:CD, the Apply icon activated but the problem didn't solved ..
So any help ..
thanx
S.
