RHEL 5.7 on VShpere - Cannot connect to internet when on static / DHCP Connection is slow
Lets prefece this with saying I AM NOT A Linux admin - this is a projecet that the company went with...
RHEL 5.7
Firewall turned off via GUI
VMWARE VShpere 4
Network
192.168.36.0/24
Gateway 192.168.36.1
Through
192.168.34.0/24
Gateway 192.168.34.240 (Gateway to Outside)
When I set the server static on the 36 network (36.6) I cannot connect to the 34 network - I cannot ping inside or outside. I did set up a route from .36/24 to the 34.240 gateway.
If I set the server to use DHCP it gets an ip address, I set the nameservers, and restart network. Then I can ping all across network and to outside; However if I go to a browser and try to open up www.redhat.com - it takes so long to connect. I have deleted the config files made sure there was no routes set.
Thoughts? I know its alot - and this is a FRESH install - maybe I missed something?

It could be something to do with your DNS server, which is 192.168.36.8.
What kind of DNS server do you have on 192.168.36.8?
Please run
nslookup www.redhat.com
dig www.redhat.com

The DNS Servers are both Server 2008.
I have attached the screen shots of the output.
Could it have something to with the NIC driver that VMware installes and RHEL doesnt like the intel NIC?

Hert is the last part of my traceroute

Do you have any Windows machine in the network and run this command in command prompt
c:\> tracert 96.6.48.112
Also on Linux do
traceroute -I 74.125.115.104 (which is www.google.com)

So from that point what I did was a FRESH install without inputing in the Install number - and for what ever reason everything is working now. I think it was installing the wrong kernal for me being on VMWARE.
Thanks for all your help.

> installing the wrong kernal for me being on VMWARE.
Every kernel upgrade requires re-configure the vmware-tools (as root, run vmware-tools-configure.pl )
It make sure the new network driver is loaded for new kernel.

Yes - I installed the VMWARE tools - I think everything is good
What IP did it get? run
/sbin/ifconfig
netstat -nr
cat /etc/resolv.conf
> I did set up a route from .36/24 to the 34.240 gateway.
So the default route on the routerA, 192.168.36.1, is set to 192.168.34.240? ===> This is required.
Also, that routerA has ip connect to 192.168.34.0/24 network?
