I'm running 1.1.5b7 under Red Hat Linux (2.0.18 kernel) and find that java.net.InetAddress.getLocalHost() throws a HostUnknownException when I'm on a PPP connection. This does not happen under Windows95 using the 1.1.6 JRE from Sun (ie. it works, and gives the PPP server-supplied IP addy). Any suggestions? I need to get my PPP-based IP addy in my application. I tried getHostByName("localhost"), but that just returns 127.0.0.1 of course. Sam Hokin | [EMAIL PROTECTED] | http://www.fusion.kth.se/~samh
