Apache trouble: help!

[Wyatt Anderson]

Well, I've had everything working fine on my Powermac 4400 running YDL 2.1
and Apache 1.3.14 or something, and then all of a sudden this afternoon, it
only accepts connections from my iBook. No other computer, even on my local
network, is able to connect. To anything. SSH, FTP, Telnet, HTTP, everything
is screwed. I have no idea what's wrong, I've rebooted, checked my settings,
etc. Is there a fix to this, or has anyone else had this problem?
