Using eth1:
Cat/etc/udev/rules.d/70-persistent-net.rules record the MAC address of the ETH1

# Vi/etc/sysconfig/network-scripts/ifcfg-eth0
Change device= "eth0" to Device= "eth1",
Change the hwaddr= "00:0c:29:8f:89:97" to the MAC address above hwaddr= "00:0c:29:50:bd:17"
# Service Network Restart

Optimize SSH connection speed:
Vi/etc/ssh/ssh_config and Vi/etc/ssh/sshd_config, setting Gssapiauthentication No, usedns=no and restarting: Service sshd restart or etc/init . d/sshd Restart
