Regarding connecting to internet from RHEL 5 server

Linux and Unix-Like Red Hat
1

Dear All,

I have a RHEL 5 server of 64 bit . I have disabled the firewalls and added the name server also in resolv.conf.

I want to connect to internet inorder to link the machine with Linux Network.

# I could not connect to any website from this server for ex

ping google.com is not working .

So I need to configure internet in this server...Pl give me some ideas on this.....

Not sure the file name in /etc,
But you need to edit a file similar
To name defaultrouter, with one line
For IP of router.

In another file you need to edit the
Box IP Address.

They are all in /etc.

Try using the system-config-network tool.

See https://access.redhat.com/site/documentation/en-US/Red\_Hat\_Enterprise\_Linux/5/html/Deployment_Guide/ch-network-config.html

Dear Murphy,

Is there any way to add http_proxy address in my export variable and then try for connecting it to internet and access google etc.

Apart from adding the proxy address profile , are there any additional steps that needs to be taken in accessing the internet.

I searched the docs mentioned by you..but could not get a clear picture...

The default firewall rules won't block access to websites.

You haven't shown us your configuration, so how can we know what's wrong?

Post the contents of:

  • /etc/sysconfig/network-scripts/ifcfg-eth0 (assuming eth0 is the correct interface)
  • ifconfig eth0 (again assuming eth0 is the correct interface)
  • /etc/resolv.conf
  • /etc/sysconfig/network

Also, are you running "RHEL" on a physical server or in a VM?

Dear Scott,

Pl find the below details.....

1.cat /etc/resolv.conf
search localdomain
nameserver      xxx.30.3.1
2.cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 82576 Gigabit Network Connection
DEVICE=eth0
BOOTPROTO=none
BROADCAST=xxx.30.7.191
HWADDR=00:21:28:E7:93:32
IPADDR=xxx.30.7.163
NETMASK=255.255.255.192
NETWORK=xxx.30.7.128
ONBOOT=yes
GATEWAY=xxx.30.7.190
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
 
3.cat network

HOSTNAME=sun2

I am running RHEL on a physical server .

Thanks and Regards
Rj
