Not really - this is a bit of a mystery. > - why did that Tomcat 5.5.29 "listen only on IPv6" until it was forced > to IPv4 by specifying "0.0.0.0" in the Connector ? The key question. > - why, when Tomcat is listening (only) on IPv6 [::]:8080, does it not > accept telnet connections on port 8080 ? Because the telnet client is likely making the request only on IPv4, since the DNS mechanism (or hosts file) probably only has IPv4 addresses in it. > - why, when Tomcat was listening (only) on IPv6 [::]:8080, did > HTTP:8080 connections from a browser on localhost work, but not > the ones from other stations ? The internal one would have connected on the IPv6 loopback ([::1]), while the outside ones most likely attempted only IPv4 connections. We don't even know if the OP's network supports IPv6 routing. > - can you set Tomcat to listen on /both/ IPv4 and IPv6 on port 8080 at > the same time ? This should be the default, and that's what 5.5.17 appears to have been doing. Why 5.5.29 doesn't exhibit the same behavior is TBD. I haven't downloaded 5.5.29 yet, but it's on my list for this weekend, to see what it does on my dual-stack machine. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
