Can't see computer from internal network
11/09/2017 9:30
I hope this is the right place to post this, as I believe it is a linuxissue.

I recently installed Fedora Core 5 on one of my home PC's. Afterinstalling I have ssh setup and running. I have two other PC's in myhouse, one a windows xp desktop, and the other a windows xp laptop(connected to the network via wireless).

Here's the situation.

1). I can ssh into the linux box from my xp desktop pc and ping it.

2). I can ping my laptop from my xp desktop and my laptop can ping myxp desktop.

3). My laptop cannot ping my linux box, nor can my linux box ping mylaptop.

I am curious if anyone has any ideas as to what might be going on? Ifmore information is needed please let me know, I'd be more than happyto provide any details.

Thanks.

Someone might be better able to advise you if you provided information aboutthe wireless access point, and the output of route print on the XP boxesand /sbin/route -n on the Linux.

11/09/2017 9:30 - On 1 Apr 2006, in the Usenet newsgroup comp.os.linux.networking, in article<1143907599.810689.212730@z34g2000cwc.googlegroups.com>, chad.angerer@gmail.com OK - local net - reach the world through 192.168.0.1. What happened to theloopback? OK - where did using 5.0.0.0 come from. That network is not currentlyallocated. Please don't pull addresses out of mid-air. There are over17 million addresses in RFC1918 you could be using for local stuff.

So it looks like two interfaces here (192.168.0.100 and 5.15.59.145) plusloopback and two interfaces here (192.168.0.105 and 5.15.61.202) plus the loopback All three systems expect to be able to talk _directly_ to each otherwithout using an intermediate router. Unless your wireless router isbridging, this won't be the case. Use a packet sniffer - and try toping the other host. Does the Linux box ask for (ARP) the MAC addressof the lapdoggy, and does the _router_ respond with it's MAC but theIP of the lapdog. Or does no one respond, because the lapdoggy never heardthe ARP. The same would be true from the lapdog - does it ARP and geta response from the router when trying to talk to the Linux box? Old guy

My router is a D-Link DI-524. It has an address of 192.168.0.1 Here is the linux routing table.
