Is there any way to find out what the IP address of another computer on a wireless network is? Is there a way to find out using finder>network?

[Peter]

no, easiest to go to your wireless router and look for a client table.

Actually, you can just ping their Bonjour address (either with ping in the Terminal or with Network Utility) and it will give you their IP.

Oooh, I have a similar question, but on a wired network, on Windows in cmd prompt if I type ping <Computername> I get its IP, in OS X in the terminal ping <Computername> gets me unknown host. Is there anyway to do this on OS X?

If it says unknown host, doesn't that mean that the machine is unreachable?

Thats what I thought, but I know the computer is there and Windows can do it. What I want to be able to do is to be able to ping or do something with the name of a computer on my network so that I can find it's IP address without having to go to the computer or use Windows.

Try computername.local

Hmm, I can do that all day long using the "ping" command in Terminal and just typing in any computer's name...

[seanc]

Tried that Simon, still doesn't work.


Would it make any difference if I said that i'm trying to ping Windows computers?

Code:
PowerMac:~ seancurran$ ping Gateway
ping: cannot resolve Gateway: Unknown host

Gateway is an old Gateway pc (funnily enough) running Windows 2000. Windows XP can ping it and give me the IP address, OS X gives me the above error.

[besson3c]

are these WIndows computers bound to Active Directory?

[besson3c]

what are your search domains set as?

Doing a "ping Gateway" (where "Gateway" is a machine name) will not work if there are no search domains defined.

[seanc]

Ah, maybe this is the problem, I have no domain . This is my home network, all WIndows computers just have a workgroup, we used to have a server and a domain and reliased there was no point in it. The servers been gone for at least a year or two and all the pcs have had Windows re-installed at least once since then so they shouldn't be getting confused.

Run tcpdump on the relavant interface, ping the broadcast address of the network, you'll get replies from everything on your subnet. Apple's ping follows standard Unix rules, so if a system isn't in a DNS table, it will have an unknown hostname. Windows probably reports a WINS name.

I see. I assume I can't ping a WINS name from OS X

[Thinine]

You might if you set the WINS server preference.

[ghporter]

Why is this in the OS X forum, when it's ALL about networking?

[seanc]

How do I set the Wins server preference?
