Context Technically a loopback address should be able to resolve immediately if it can connect or not. But for IPV6 loopback ::1 (to port that is not been bounded), this is not the case and the client may be waiting for the socket to get connected up to the maximum 3-4 mins timeout. (If you are on the global zone, it is ok). In global zone with IPv6 for localhost # telnet ::1 9999 telnet: Unable to connect to remote host: Connection timed out <- Quite immediately In localzone with (IPV6 on lo0:1) # telnet ::1 9999 ..... telnet: Unable to connect to remote host: Connection timed out <- 3 mins 40 sec later Is this something wrong with zones/ip (for ipv6) compared to global zones. PS: This is consistent across all the other machines Config SunOS v4u-xxxx 5.10 Generic_118822-25 sun4u sparc SUNW,Ultra-2 Solaris 10 1/06 s10s_u1wos_19a SPARC TESTCASE 1. Enable IPV6 on globalzone 2. Create a local zone with IPv6 on hme0 3. Boot the zones ---------------------------------------- # zonecfg -z zone3 info zonepath: /zones autoboot: false pool: inherit-pkg-dir: dir: /lib inherit-pkg-dir: dir: /platform inherit-pkg-dir: dir: /sbin inherit-pkg-dir: dir: /usr net: address: 10.t.x.y physical: hme0 net: address: fe80::a00:20ff:fe9a:999c/10 physical: hme0 -------------------------------------------- 4. Use the localzone /usr/apache2/bin/apachectl start (after configuring /var/apache2/httpd.conf) so that say telnet ::1 80 works (in the zone3) 5. Now do telnet ::1 80 --> OK telnet ::1 9999 -> FAILS Dtrace on fbt:::: OK |-> 2006 Jul 13 23:17:44 telnet 112464627215 sockfs.sowaitconnected tid=1 3298560182936 3 |<- 2006 Jul 13 23:17:44 telnet 112464627256 sockfs.sowaitconnected tid=1 164 0 Not OK |-> 2006 Jul 13 23:00:29 telnet 111429905553 sockfs.sowaitconnected tid=1 3298560182936 3 |-> 2006 Jul 13 23:00:29 telnet 111429905597 genunix.cv_wait_sig_swap tid=1 3298560182984 3298560182968 ... |<- 2006 Jul 13 23:04:14 telnet 111654582049 genunix.cv_wait_sig_swap_core tid=1 612 1 |<- 2006 Jul 13 23:04:14 telnet 111654582096 sockfs.sowaitconnected tid=1 140 3298560182936 |
