I'm looking for a good tutorial on traceroute. Specifically, I'm looking for a discussion of the different responses you can get, especially "network unreachable". I recently saw an excellent discussion of this, I thought in a Linux tutorial/manpage. But now I don't remember where I saw it. Anybody know where I can find such a thing? __________________________________________________ Do You Yahoo!? Get Yahoo! Mail – Free email you can access from anywhere! http://mail.yahoo.com/
