Hi, Iam using 2.4.26 linux source and patch it with uml-patch-2.4.26-3 patch. I have built the uml binary with ipv6 support and my host has ipv6 module loaded. The telnet client and daemon are IPV6 supported on the Host machine. Iam able to telnet on the localhost with ipv6 address. For example to telnet on localhost with loopback address ( ::1 ) , it works fine. Now Im running uml on this host (RedHat 9) with command as follows: ./linux ubd0=guest1.diff,root_fs con=port:9001 con0=fd:0,fd:1 umid=guest1 mem=32m Now when i try to telnet on UML with following command : telnet 127.0.0.1 9001, it works fine But if I telnet with : telnet ::1 9001 it gives message connection refused. Can anyone throw some light on it why this is happening??? Thanks and Best Regards, Adil Mujeeb |

You didn't mention if the UML guest had the ipv6 module loaded. Also, you need to telnet to the *host's* port 9001, since the exterior of UML is offering the connections, not the interior. To test ipv6 on the guest, you could configure inetd or xinetd on the guest to serve telnet. Or assuming that off-site networking is configured, you can try to actually telnet from the guest to the host, or to another machine on your net that will accept your telnet connection. Remember that telnet is not encrypted, so plain text passwords are exposed and stealable if you connect across the network. I always use ssh or slogin. It's a good way to get a session on another machine, such as the UML guest, but you need to have networking functional on the guest first. James F.
