I have gone through several of the forums regarding setting up static IP address on RHEL. But I couldn't able to ping any IP address either within the same subnet or outside. Even I can't ping host IP or default gateway. All I get back is "Destination Host Unreachable".
I can get reply incase when I ping - localhost , IP_address (9.145.136.112).

I shall detail out the steps I followed.

Edited "/etc/sysconfig/network-scripts/ifcfg-eth0" to have the below shown contents

DEVICE="eth0"
HWADDR="00:50:56:9B:00:04"
IPADDR="9.145.136.112"
NETMASK="255.255.255.0"
NM_CONTROLLED="no"
ONBOOT="yes"
BOOTPROTO="static"
TYPE="Ethernet"
GATEWAY="9.145.136.1"

Added GATEWAY IP in /etc/sysconfig/network file

Added DNS IP in /etc/resolv.conf

Finally restarted the network service. Is there anything else I need to follow.
I am doing this installation as a guest machine on VMware host.

Couple of days back I did for ubuntu and it worked as charm.
Steps I followed in that case are
1. added IP details in /etc/network/interfaces
auto eth0
iface eth0 inet static
address 9.145.136.112
netmask 255.255.255.0
gateway 9.145.136.1
2. updated DNS IP
3. ifup eth0

I mentioned the ubunu steps just to show there is no issues with respect to HOST to Guest bridging .

You don't mention what the actual problem is.

- Which command/step doesn't seem to work?
- Any warning/error messages?

RHEL sets up pretty conservative firewall rules by default. Check that icmp is not blocked by iptables.

I have stopped iptables and turned it off. No luck.

an another info... When I tried to ssh to a ip in same subnet( sure its a linux box), I ge t the following error message.

"ssh : connect to host 9.145.136.110 port 22: No route to host"

I tried to check the output of "route -n" command, which is as below

-----------------------
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
9.145.136.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0
0.0.0.0 9.145.136.1 0.0.0.0 UG 0 0 0 eth0
-----------------------

Show your ifconfig -a.
Also show your arp -a after you tried to ping some host in your subnet.

check if the ip address and route right
check if the vmware network setting is bridge mode

thanks guys.. culprit is vmware n/w settings.. I am bale to resolve it now..
thanks again for all your help
