You can check what mode is enabled before:
# ethtool eth1
to change:
# nano /etc/sysconfig/network-scripts/ifcfg-eth1
ETHTOOL_OPTS="speed 1000 duplex full autoneg off"
Restart Interface:
# ifdown eth1 && ifup eth1
Confirm:
# tail -30 /var/log/messages # ethtool eth1
with the command ifconfig -a you’ll see all the network interfaces which are installed.
To set an IP address make:
$ ifconfig "interfaces" x.x.x.x netmask x.x.x.x
$ ifconfig ath1 172.0.0.2 netmask 255.255.255.0 up
these commands as root.
T0 set a default gateway
$ route add default gw x.x.x.x
To add the dns resolve address locate the resolv.conf file and write them on it.
$ nano /etc/resolv.conf
nameservers 200.00.00.00
save and close.
