3 machines and no sharing

demonace · #1 October 6th, 2009, 01:55 PM

I have 3 machines and they are all on the same subnet, (192.168.1.x), all have the same subnet mask, and gateway.

I have web servers on 2 of them, they can view the site locally, but not from another machine.

They all have web sharing enabled.

Machine - IP - subnet mask - gateway
Machine 1 – 192.168.1.166 – 255.255.255.0 – 192.168.1.1
Machine 2 – 192.168.1.106 – 255.255.255.0 – 192.168.1.1
Machine 2 – 192.168.1.131 – 255.255.255.0 – 192.168.1.1

All 3 can get on the internet.
All 3 can ping the gateway.
All 3 can ping the printer (192.168.1.58)
They are not able to ping each other at all.

I have done a good bit of research, still not able to get them to talk to each other.

Any other ideas where machines on the same subnet are not able to talk to each other?

Are all 3 Mac OS X?
What exact version of OS?

If they are Mac OS X, are you sure "Enable Stealth Mode" is not enabled? System Preferences > Security > Firewall > Advanced.

Do you have any firewall enabled on the router or on your computers?

2 of the machines are 10.5.8, without stealth enabled.
1 machine is Vista.
Not worried about the Macs connecting to the windows machine, trying to get the web sharing working to remote machines.
I have checked that the firewall is turned off on vista, and both OSX machines have "Allow all incoming connections" enabled.

They are connected to a network hub, non-switched.

Are those with dhcp or static or manual ip?
What's your gateway?

Are you pinging by IP address, or computer name?

Are you saying that, for example, there's a web server on machine 192.168.1.106, and if you open Safari on, say, machine 192.168.1.166 and type "192.168.1.106" in the URL bar, you get... an error message? A 404 page? A "could not resolve host" message?

What router are you using? Did you open the correct ports ("Well known" TCP and UDP ports used by Apple software products) on your router to allow local sharing?

Thanks for the tips,

Giaguara: They are all DHCP right now, can switch to static if needed. I have verified the IP of each machine before pinging.

Its in a business environment, not sure what the gateway is.

I have setup a Redhat and Windows 2008 servers, which had served as web servers with no issues.

ElDiabloConCaca: I am pinging by IP address. And I do not get any 404s, just timeouts.

Satcomer: I'll try to check with the group that supports/maintains the router, but I do not think that would be the issue as previous machines (see above) were brought up as web servers with no issues.
