Fedora Core 6 cannot ping WinXP LAN

DSL gateway: 192.168.0.1
D-Link router: 192.168.1.1

WinXP 192.168.1.100
Linux 192.168.1.101

I can open a shell to the linux machine. I can ping the linux
machine. I cannot ping the WinXP machine from the linux machine. The
linux machine can get to the internet and can successfully ping
cnn.com. It can also ping both the DSL modem and the router.

I've read over a good many posts on here about the same subject but I
was not able to find an answer specific to my problem. I'm not
worried about samba. This is more about the linux machine hosting an
oracle database and running an application server that needs to be
accessed by the WinXP machine on the LAN.

What brought this to the surface was trying to install oracle through
an xsever. The DISPLAY=192.168.1.100:0.0 but this failed...started
troubleshooting and it appears that the linux machine cannot see the
WinXP machine.

Any help or advice would be greatly appreciated.

Thanks.

Microsoft Windows does not behave well with 255.255.0.0 netmask addresses.
I would try and extend the subnet mask to 255.255.255.0 and
change the address of the DSL gateway to 192.168.1.xxx if possible.

Regards,

Mark.

Is your XP machine running SP2?
If so, is the firewall enabled?
I believe the default firewall settings in XP SP2 is not to reply on ping.
You might have to change some firewall settings, at least during the Oracle
install.

Verify that the netmask (255.255.254.0?) on both Linux and Windows is the
same.

Sounds like you need to change your Windoze firewall settings, a
discussion of this, of course, would be off-topic in this NG.

Windows does not have xsever (sic). Did you install one?

Here's how this was resolved:

WinXP firewall was turned off. ZoneAlarm unblocked traffic from
192.168.1.101. WinAxe was installed as the xserver.

I was able to successfully install the oracle instance and the
application server.

What remains is that I'm not able to access the management pages for
the oracle instance from WinXP. The hostname is set on the linux
machine, both in /etc/hosts and /etc/sysconfig/network. The app pages
load fine from the linux machine. (httpd.conf ServerName is set
correctly to match the hostname of the linux machine). I have the
entry in the windows /etc/hosts as:

192.168.1.101 servername.domain.com (in example). I'm able to ping
the linux box by servername.domain.com, but can't get pages from the
linux machine to load on the WinXP:

http://severname.domain.com/em (in example)

I'm not sure what I'm overlooking, but based on the previous firewall
issues I wouldn't be so bold to think its not something simple.

Thoughts?

This is definately firewall related; likely down at the router level.
I'm going to close this out and get off this group.

Folks, thank you very much for the help and guidance. Much
appreciated.
