Ping Windows machine from Linux

mselaledi · 09-30-2010, 09:03 AM

I am interested in testing if two computers can communicate with each other.
Infrastructure: Computer A - Windows Machine
Computer B - Linux Machine

I am able to successfully ping B from A, but cannot do the same visa versa.
Both A and B are on the same network with the same Netmask of 255.255.255.0

Please provide me with suggestions.

In all probability, the linux computer's firewall is configured to drop ping packets. Check your firewall settings on the linux box.

I have checked the firewall settings, and still no results.

Post your distro and what tools you are using to check your firewall configuration. Also, post exactly what commands you are running on your windows box to ping your linux box and what output you get when you run those commands. Finally, open a console on your linux box and run either:

$ sudo ifconfig

or if you have a root account:

$ su
<enter root password>
# ifconfig

and post the output here.

The problem does not lie when pinging from Windows, but from pinging from Linux.

I'm going to have to read these posts more carefully. Sorry about that.

OK. Reverse the steps then. First check your windows firewall(most likely source of problem). Turn it off and see if you can ping the windows box from linux. If you can, the problem is with the windows firewall configuration. If that doesn't help, open a dos prompt in windows and run:

ipconfig

and post the output here. Post the command you run on the linux box to ping windows and the output.

Kilgoretrout is correct: newer versions of Windows (Vista, Server 2008 and Windows 7) all disallow "ping" by default. Here's one way to re-enable ping:

By design, Vista doesn’t allow any ICMP pass though the firewall and you can’t ping it. However, you may have two options.

A. You can create inbound rule for ICMP using Windows Firewall with Advanced Security. To do this, please follow these steps.

1) Open Administrative Tools from Control Panel.

2) Double-click Windows Firewall with Advanced Security.

3) Double-click Inbound Rules.

4) You may find File and Printer Sharing (Echo – ICMPv#-In). The # can 4 for IPv4 and 6 for IPv6.

5) Decide which one you want to enable and highlight, then click Enable Rule.

B. Whenever the exception for File and Printer Sharing is enabled, Windows Firewall automatically enable ping.

Try typing this in a terminal, OP:

Code:

sudo ping -f www.microsoft.com

You are absolutely correct. And the problem is *caused* by Windows (specifically, the default firewall/network configuration of Windows Vista and higher).

Please read my earlier post and let us know what happens!

Thank you .. PSM
