Trying to set up a static ip so I can ssh in using putty on fresh centos 6.3 install

Xitherius · 01-28-2013, 12:06 AM

I have changed the ifcfg-eth0 file to the following

DEVICE=eth1
NM_CONTROLLED=yes
ONBOOT=yes
HWADDR=00:11:43

2:32:43
TYPE=Ethernet
UUID=6a129ba5-6430-40cc-b863-882ec2f3d34d
BOOTPROTO=static
NAME="System eth0"
IPADDR=184.70.179.154
NETMASK=255.255.255.252
GATEWAY=184.70.179.153
USERCTL=no
DNS1=64.59.184.13
DNS2=64.59.190.242

the DNS are the ones supplied by my network provider

here is what I get when I do ifcfg -a

[root@OHS network-scripts]# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:11:43

2:32:43

I can ssh in using the dynamic ip which is the one listed for eth1
but when I try to connect using the static ip the connection times out

can someone help please

thanks in advance,

Have a look at the doc here -->http://www.centos.org/docs/5/html/5....aces-eth0.html

Which interface are you trying to ssh in on? There should be a file for each. The IP address showing for eth0 is what you have specified. If you are trying to ssh on eth1, then you are in the wrong config file.

I don't know how to set up the putty client to use different interfaces. I expected that it didn't matter.
Thanks,

You just specify the IP address and correct port.

Can you ping from the clinet system to the IP address you are trying to ssh to? If not, there is a network problem to understand.
