Re: Can't ping Windows XP guest OS from Linux host...

bringert · ‎02-21-2007

I have Windows XP running as a guest under VMWare player on an Ubuntu host. I use NAT for the guest and networking works fine from the guest. The problem is that I can't ping or connect to any ports in the guest from the host.

I'm running VMWare Player 1.0.3 build-34682 under Ubuntu Dapper, kernel 2.6.15-28-amd64-k8. The guest OS is Windows XP SP2 with all security updates. I have turned off the Windows XP firewall.

On the host:

In order to see your guest from the outside world when the guest is NATted, you need to set up port forwarding. See either the Server or Workstation manual -- http://www.vmware.com/support/ws55/doc/ws_net_nat.html

KevinG · ‎02-21-2007

The host computer has a host virtual adapter on the NAT network (vmnet8) (identical to the host virtual adapter on the host-only network(vmnet1)). This adapter allows the host and the virtual machines to communicate with each other. You should be able to access the guest from the host without any port forwarding setup. If you want to access the guest from any system other than the host, you will need to setup port forwarding.

bringert · ‎02-23-2007

KevinG: Yeah, that's what I expected, but it doesn't seem to work. Do you have any ideas for what I could check?

One thing that confuses me is that the host has 192.168.90.1 as the address of vmnet8, but the guest uses 192.168.90.2 as the gateway. It seems to work fine for the guest, but is it correct?

Adding port forwarding to the guest made it possible to contact the guest from the host, thanks. It seems like overkill though, I don't want to allow the whole world to talk to the guest. I just need to be able to reach it from the host.

The 192.168.90.1 is the address of the virtual network adapter vmnet8.

The 192.168.90.2 is the NAT service, which is the gateway to the outside world

Not to rehatch an old problem, but...

I have the exact same problem, RHEL 3 host, XP Guest, NAT. I can't ping or contact the guest in any way from the host via the command line. Interesting that I can contact a 2000 SP4 Guest though....

So I followed what you guys have recommended and I vi-ed my nat.conf file per the documentations instructions. I did a test with telnet. I enabled telnet on the guest (port 23) in nat.conf I add the line:

\[incomingtcp]

8889 = 192.168.0.128:23

I restart vmware. If I do a netstat -an |grep 8889 I can see that vmware is now listening on 8889 if I do a telnet localhost 8889 it times out. Doing a netstat -an on the guest shows that 23 is listening but nothing ever connects. I tried telnet 192.168.0.2, 1, 127.0.0.1, etc, etc.

The guest is 192.168.0.128. Is there anything more I have to do than just restart vmware? Does the guest need some sort of change?

jakestokes · ‎03-23-2007

To anyone that reads this here is the solution to my problem, and why it seems that the problem is with XP:

The problem is with XP. When you build a new XP anything, it defaults the firewall to on... The XP firewall blocked my incoming pings, nat.conf port forwardings, pretty much everything... I turned it off and everything worked.
