We have two network interfaces, one is for connecting CERN network and the other is for DCS network.



CERN network:
*************

[root@pcalitrd00]# cat /etc/sysconfig/networking/devices/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=dhcp
HWADDR=00:13:77:36:d0:3b
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes



DCS network:
************

[root@pcalitrd00]# cat /etc/sysconfig/networking/devices/ifcfg-eth2
# Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+
DEVICE=eth2
ONBOOT=yes
BOOTPROTO=none
IPADDR=10.160.144.181
NETMASK=255.255.0.0
HWADDR=00:10:60:77:03:5D
TYPE=Ethernet



Wireless network:
************

[root@pcalitrd00]# cat /etc/sysconfig/networking/devices/ifcfg-eth0
# Atheros Communications, Inc. AR5005G 802.11abg NIC
DEVICE=eth0
ONBOOT=no
BOOTPROTO=dhcp
HWADDR=00:16:E3:EB:DB:01

Remark: 
*******
CERN network is registered as pcalitrd00.cern.ch
DCS network setting is already done in laptop

alitrdwn005 is accessible through
mount alitrdwn005:/data/dcsnfs /data
