[EMAIL PROTECTED]:~$ lsmod | grep ipv6 ipv6 268960 12 I guess 2.5 :) Ubuntu reports it as 2.5-0ubuntu14 [EMAIL PROTECTED]:~$ ls -al /lib/libc.so.6 lrwxrwxrwx 1 root root 11 2007-05-18 01:12 /lib/libc.so.6 -> libc-2.5.so I think that telnet could see that "::1" is the IPv6 loopback string and replace it with "127.0.0.1" if it wanted. Haven' looked at the code, just why this behaviour may be possible.
In case anyone wanna try.. test attached.
This is the output: getaddrinfo AF_UNSPEC/SOCK_STREAM/AI_ADDRCONFIG failed so, yes: hints.ai_flags = AI_ADDRCONFIG; makes getaddrinfo fail. -- Lucian Adrian Grijincu
