Or, at least you should update libc/net/getaddrinfo.c and libc/net/name6.c I don't know why getaddrinfo(3) fails for localhost query, exactly. However, probably updating to 4.1-RELEASE fixes your problem. cactoss> I tried to look at the sources for telnet. In file commands.c:2292, there's cactoss> an assignment of variable "family". I couldn't understand where the variable cactoss> is coming from. The variable `family' is came from command line of telnet. If -4 is specified, telnet tries only AF_INET. If -6 is specified, telnet tries only AF_INET6. Default is AF_UNSPEC, that is try both IPv6 and IPv4. cactoss> Could you please take a look at `ifconfig lo0`: cactoss> lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 cactoss> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x6 cactoss> inet6 ::1 prefixlen 128 cactoss> inet 127.0.0.1 netmask 0xff000000 cactoss> Does it look okay? It seems fine. cactoss> One question. Firewall rules apply to both IPv4 and IPv6, right? There cactoss> shouldn't be separate rules to IPv6, should there? No. Rules for IPv6 is set separately by ip6fw. Firewall for IPv6 is enabled by specifying `options IPV6FIREWALL' in your kernel config. -- Hajimu UMEMOTO @ Internet Mutual Aid Society Yokohama, Japan ume@mahoroba.org ume@bisd.hitachi.co.jp ume@FreeBSD.org http://www.imasy.org/~ume/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
