Yes, you can do that.

There are several applications that can help you deal with this.For
example, you can use a network snnifer, to see what's goin on with your
network. Some Wireless routers have a status log, where you can see the
internal ip, the external ip, the port that's been used, the protocol,
and some other things...

Depends on what you're expecting to see. If you want to see what's on the
other screen, then no network tool will do that. You'd need to have remote
desktop, vnc or some other tool installed and configured on it in order to
'see the screen'. If you just want to watch what packets are going across
the airwaves then you could use something like the 'ethereal' program.

It's a packet sniffer and it'll let you capture the raw packets and then
examine them. It won't reassemble complete web pages or pictures. But
it'll show you things like what domain names are being sought, mail sessions
(or at least parts of them) and more.

The better question is WHY do you want to do this? What are you trying to
watch and why? There are other tools available but their costs and
complexities might not make them practical. But you'd have to explain what
you're after first.

Of course, if the original poster had bothered to disclose the maker
and model of his wireless router, the guesswork could be minimized.

I sniff my traffic regularly to keep an eye on what's moving over the
neighborhood LAN. I use Log Viewer 2.1 SP1
http://svs.sv.funpic.de
for the purpose. I supports a limited subset of Linksys hardware,
which are able to send syslog entries as SNMP traps. The WRT54G
running alternative software with SNMP enabled can allegedly do this,
but I can't remember how I did it.

For some others, I use LinkLogger ($50):
http://www.linklogger.com

Both display the URL's accessed by various connections which is all I
really need to figure out what they're doing. The only problem is
that neighbors aspiring delinquent is now surfing via a content
filtering proxy server, which keeps him off the porno sites. I can't
tell what he's browsing as the log viewer shows the proxy server site
for everything.

Oh lovely. Log viewer shows that I'm being probed and possibly
attacked by a local ISP's DNS server. Now what?
