Question

I have just started a networking module in college and am really interested in this area, and would like to continue in this career path. I have tried to get an answer from my lecturer but she cant give me one, so here it is for you.

Is it possible to intercept information across a wirless network (which i have access to) as in IM messages/ emails etc, which is being sent by another pc on the network (home)?

If so is there a commercially available program to do this.

sorry if this is a stupid question, but im really interested to find out ASAP.

Interested to find out ASAP, intercept across wireless the IM's/emails to a system on a home network...doesn't exactly sound like you're doing this with the best of (legitimate) motivations. — Bart Silverstrim, May 30 '12 at 18:19
This is really more of a [security](http://security.stackexchange.com) question, and a bad fit anyway because... well, *Google*! — voretaq7, May 30 '12 at 18:32

Assuming they're not using SSL, yes.
And it's not hard.

If so is there a commercially available program to do this.

Yes. And a bunch of free ones. And you can do it yourself with tcpdump / ethereal / wireshark if you're sufficiently motivated.

If your lecturer is unable to answer they are not worth what you're paying for the class.
If they are unwilling to answer, see Bart's comment on your question.
