Can't Ping Linux CentOS 5.3 Machine to XP SP2 Windows Machine

[Moderns]

Dear Mates,

I have two machines, one has XP service pack2, second one has CentOS 5.3 (Linux), they are connected through crossover cable.


I have configured everything fine but don't know why till now can't ping!

A. Windows machine settings as follows:

IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gatway: 192.168.1.1
+ Firewall is turned OFF.

B. For Linux machine, I will list everything stored in network files, logged as [root@localhost ~]# :

1. /etc/sysconfig/network:

ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
route add default gw 192.168.1.1 eth0
NETWORKING = yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain



2. /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
IPADDR="192.168.1.4"
NETMASK="255.255.255.0"
ONBOOT="yes"
BOOTPROTO="yes"



3. /etc/resolv.conf

nameserver 192.168.1.4
search locadomain



4. I restarted network service using this command:

/etc/init.d/network start

everything is fine.

When checking using ifconfig command.

I get the following:

eth0 Link encap: Ethernet HWaddr 00:08:0D:EE:19:66
inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr:........
UP BROADCAST RUNNING......
RX....
TX....
collisions:0........
RX bytes:0 (0.0 b) TX bytes:......

lo Link encap: Local Loopback
inet addr: 127.0.0.1 Mask:255.0.0.0
inet6 addr:........
UP LOOPBACK RUNNING......
RX....
TX....
collisions:0........
RX bytes:0 (0.0 b) TX bytes:......

I mean I assigned the IP: 192.168.1.4 to Linux machine (Eth0).

I did everything above and can't ping till now, when pinging from windows or linux I get a message "destination host unreachable" restarted Linux many times but same result. NETWORK CABLE is working fine I tested it.

Please advise me.

Thanks guys.

CentOS 5.3 commands are similar to Redhat commands.

I hope to find answer soon here, waiting you.

Thanks.

I like clean config files so lets start out with the simple things.

A. Windows machine settings as follows:

IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gatway: 192.168.1.1
+ Firewall is turned OFF.

Ensure the firewall is turned off.

1. /etc/sysconfig/network:

ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
route add default gw 192.168.1.1 eth0
NETWORKING = yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
GATEWAY=192.168.1.1

Remove the RED statements above. They are not needed.
Add the BLUE statement to this file

2. /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
HWADDR=00:08:0D:EE:19:66
IPADDR="192.168.1.4"
NETMASK="255.255.255.0"
ONBOOT="yes"
BOOTPROTO="yes"
BOOTPROTO="static"

Add the first BLUE line and replace the RED statement with the second BLUE statement.

After the above is done restart the network with;

service network restart

I mean I assigned the IP: 192.168.1.4 to Linux machine (Eth0).

I did everything above and can't ping till now, when pinging from windows or linux I get a message "destination host unreachable" restarted Linux many times but same result. NETWORK CABLE is working fine I tested it.

How did you test the cable?

Post the output from the following command;

route -n

On the windows maching please post the output from the following;

route print

Hi Robert,

Thank you very much for your efforts.

Actually I just solved the problem before few hours and had internet connection problem couldn't post here immediately.

I removed all gateway statments like:

"Default Gatway: 192.168.1.1"
"route add -net 192.168.1.0 netmask 255.255.255.0 eth0"
"route add default gw 192.168.1.1 eth0" from Linux files also didn't include it in windows.

The problem was the driver of Local Area Network (LAN), it was not the right driver, I changed the driver to the correct one and now able to ping from linux to windows and vise verse.

However your comments are so useful and I will take them in regards.

Thanks again and I hope it's clear to all

Regards,
