Hello,

In my imac I've got this strange problem. Executing ruby's testsuite will take a very long time. I've isolated the reason to resolving of "localhost" address. The ruby uses getaddrinfo. At the end o fthis mailis a test code that show this strange behaviour. Running it will give the following output

./test localhost resolving name=localhost family=30 sock_type=1 protocol=6 flags=0x0 canonname=(null) ip=::1 serv=0 family=2 sock_type=1 protocol=6 flags=0x0 canonname=(null) ip=173.19.2.144 serv=0 family=2 sock_type=1 protocol=6 flags=0x0 canonname=(null) ip=127.0.0.1 serv=0.

Eg. the first localhost ip is "173.19.2.144". This IP is not configured in my mac. Here is the ifconfig -a

hmm. i cannot seem to repeat the symptom with my iMac G5 + OS 10.4.9 with your sample program. is there any way to detect libc version? itojun@the author of "IPv6 network programming" book itojun[imac-itojun-org:~] ./a.out resolving name=localhost family=30 sock_type=1 protocol=6 flags=0x0 canonname=(null) ip=::1 serv=0 family=2 sock_type=1 protocol=6 flags=0x0 canonname=(null) ip=127.0.0.1 serv=0 itojun[imac-itojun-org:~] ifconfig -a lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280 stf0: flags=0<> mtu 1280 en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::214:51ff:fe98:9f98%en0 prefixlen 64 scopeid 0x4 inet 221.249.121.230 netmask 0xfffffff8 broadcast 221.249.121.231 inet6 2001:240:501::214:51ff:fe98:9f98 prefixlen 64 autoconf ether 00:14:51:98:9f:98 media: autoselect (1000baseT <full-duplex>) status: active supported media: none autoselect 10baseT/UTP <half-duplex> 10baseT/UTP <full-duplex> 10baseT/UTP <full-duplex,hw-loopback> 100baseTX <half-duplex> 100baseTX <full-duplex> 100baseTX <full-duplex,hw-loopback> 1000baseT <full-duplex> 1000baseT <full-duplex,hw-loopback> 1000baseT <full-duplex,flow-control> 1000baseT <full-duplex,flow-control,hw-loopback> en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 00:14:51:86:f0:19 media: autoselect (<unknown type>) status: inactive supported media: autoselect fw0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 4078 lladdr 00:14:51:ff:fe:98:9f:98 media: autoselect <full-duplex> status: inactive supported media: autoselect <full-duplex> itojun[imac-itojun-org:~] uname -a Darwin imac-itojun-org.local 8.9.0 Darwin Kernel Version 8.9.0: Thu Feb 22 20:54:07 PST 2007; root:xnu-792.17.14~1/RELEASE_PPC Power Macintosh powerpc itojun[imac-itojun-org:~] ls -l /usr/lib/libc.dylib lrwxr-xr-x 1 root wheel 15 Dec 14 16:00 /usr/lib/libc.dylib -> libSystem.dylib itojun[imac-itojun-org:~] ls -l /usr/lib/libSystem.dylib lrwxr-xr-x 1 root wheel 17 Dec 14 16:00 /usr/lib/libSystem.dylib -> libSystem.B.dylib itojun[imac-itojun-org:~] ls -l /usr/lib/libSystem.B.dylib -r-xr-xr-x 1 root wheel 4406292 May 26 09:01 /usr/lib/libSystem.B.dylib itojun[imac-itojun-org:~] md5 /usr/lib/libSystem.B.dylib MD5 (/usr/lib/libSystem.B.dylib) = 25ee99bbf8ecce741b1be22a4417341b _______________________________________________ Do not post admin requests to the list.
