is this a linux or a solaris system? on linux, you have separate tools for v4 and v6, so "ping" would still return the v4 address (on solaris, the regular ping would try v6 unless you brost@linuxbox:~# ping -n portrix-systems.de PING portrix-systems.de (46.30.25.51) 56(84) bytes of data. 64 bytes from 46.30.25.51: icmp_seq=1 ttl=58 time=19.9 ms 64 bytes from 46.30.25.51: icmp_seq=2 ttl=58 time=16.0 ms --- portrix-systems.de ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1007ms rtt min/avg/max/mdev = 16.000/17.999/19.999/2.003 ms brost@linuxbox:~# ping6 -n portrix-systems.de PING portrix-systems.de(2a02:22f0:3:bb90::51) 56 data bytes 64 bytes from 2a02:22f0:3:bb90::51: icmp_seq=1 ttl=60 time=20.0 ms 64 bytes from 2a02:22f0:3:bb90::51: icmp_seq=2 ttl=60 time=16.0 ms Same is valid for traceroute and nslookup. That is why I asked you to try "host", or you could try "dig AAAA" > So even though my SRS has IPv6 enabled, I'm not seeing that come into play > when doing name lookups.

You could also snoop your dns traffic to check if during the lookup, it asks for (and gets AAAA records) > I considered the IPv6 angle [I know nothing about IPv6] but thought it was > suspect because from that SRS, uttsc works with other WTSs; it's only this > one particular WTS that's giving the SRS uttsc problems. But that does not mean you should rule it out. Maybe the other names don't have AAAA entries. Or maybe they all do but ipv6 is only "broken" on one of them. > The other reason was that I'm pretty sure IPv6 has been enabled on this > interface for some time now since I built it maybe a year ago [not sure why I > enabled IPv6]. Because it is the right thing to do. We all have to accept that IPv6 is going to become more and more relevant. > I can just unplumb/delete the IPv6 on that interface without affecting the > existing IPv4 config, right? I think so but you better test and try this first. Or simply do a snoop on your interface and filter for ipv6 traffic to confirm if it tries to connect that way first Bjoern _______________________________________________ SunRay-Users mailing list [email protected] http://www.filibeto.org/mailman/listinfo/sunray-users
