Although the later does seem to belong to a router, as it runs RomSShell_4.61 [1] As a workaround, a bit of googling suggests that writing DEFAULT_IP=IP_VERSION4 into /etc/default/inet_type should disable ipv6. Unplumbing the inet6 interfaces should also leave with a working ipv4 system until it is fixed.

I dont see any problem there. Do you? So record is missing at dns. If dns cannot be changed ipv6 address must be added to /etc/inet/ipnodes (which is always a good idea if dns is not 100% reliable). /usr/lib/inet/in.ndpd is running. ifconfig -a6 shows that the ip address is configured three times as local interface for the same physical interface. Is this expected? And physical interface bnx0 is associated with a link local address only. This shows that the router is not propagating the site prefix. So you must change the router config or add the site prefix locally. Maybe interfaces were not plumbed. I'd really like to reboot tomorrow. Everytime I do what is the equivalent to /etc/init.d/networking restart it adds an interface with the v6 address. The next try from my side would be to switch back to the old v6 range to see if the problems all go away. I currently cant reach even from the same network. root@willow:~# ping 2a02:ec80:101:301::2:2 ^C Solaris is not my home base system but I only changed the prefixes in the config files so it should work as it did before. Lets see how this goes tomorrow after some sleep.

[Toolserver-l] IPv6
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, During the next maintenance window I plan to start the (somewhat overdue) deployment of IPv6 at the Toolserver. In preparation for this, I will be adding IPv6 addresses to all hosts today. I don't expect this to cause any problems for users, except that the IP address for willow (which already has one) will change. I will leave the old IP in place until everything has migrated, but the new IP will be used for outgoing connections. - river. -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.11 (SunOS) iEYEARECAAYFAk3h5w4ACgkQIXd7fCuc5vIc4QCggvuH0CpZ1scPjb82g8xjxcmX IkoAoK8xKuYW2WO8Zqv4T8qUbamZPAvQ =c2zi -END PGP SIGNATURE- ___ Toolserver-l mailing list (Toolserver-l@lists.wikimedia.org) https://lists.wikimedia.org/mailman/listinfo/toolserver-l Posting guidelines for this list: https://wiki.toolserver.org/view/Mailing_list_etiquette
