Hi,

For whatever reason, we're investigating/learning IPv6 on our (me + friend of mine) lab network where a couple of x86, sparc, alpha and of course mips machines are running. IPv6 under Linux/x86 seems pretty solid:

Code: Select all


root@magna:/# host -t AAAA ipv6.google.com


ipv6.google.com is an alias for ipv6.l.google.com.


ipv6.l.google.com has IPv6 address 2001:4860:a003::68


root@magna:/# host 2001:4860:a003::68


8.6.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.3.0.0.a.0.6.8.4.1.0.0.2.ip6.arpa domain name pointer fx-in-x68.google.com.


root@magna:/#

However, doing the same thing under IRIX seems rather broken?

Code: Select all


speedo 2# host -t AAAA ipv6.google.com


ipv6.google.com is an alias for ipv6.l.google.com.


ipv6.l.google.com has AAAA address 2001:4860:a003::68


speedo 3# host 2001:4860:a003::68


Host \[x20014860A00300000000000000000068/128].ip6.arpa not found: 1(FORMERR)


speedo 4#

Anyone have a clue what's going on?

Further oddities:

Code: Select all


speedo 5# host -n 2001:4860:a003::68


Host 8.6.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.3.0.0.a.0.6.8.4.1.0.0.2.ip6.int not found: 3(NXDOMAIN)


speedo 6#

...which seems about right. IP6.INT is obsolete.

I don't see anything wrong on 6.5.30

Code: Select all


julien@speedy > uname -R


6.5 6.5.30m


julien@speedy > host -t AAAA ipv6.google.com


ipv6.google.com is an alias for ipv6.l.google.com.


ipv6.l.google.com has IPv6 address 2001:4860:a003::68


julien@speedy > host 2001:4860:a003::68


8.6.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.3.0.0.a.0.6.8.4.1.0.0.2.ip6.arpa domain name pointer fx-in-x68.google.com.


julien@speedy > host -n 2001:4860:a003::68


8.6.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.3.0.0.a.0.6.8.4.1.0.0.2.ip6.arpa domain name pointer fx-in-x68.google.com.

Not so good on 6.5.22m on an Indy...

Code: Select all


bash-2.05b$ uname -R


6.5 6.5.22m


bash-2.05b$ host -t AAAA ipv6.google.com


ipv6.google.com is an alias for ipv6.l.google.com.


ipv6.l.google.com has AAAA address 2001:4860:b002::68


bash-2.05b$ host 2001:4860:a003::68


Host \[x20014860A00300000000000000000068/128].ip6.arpa not found: 1(FORMERR)


bash-2.05b$ host -n 2001:4860:a003::68


Host 8.6.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.3.0.0.a.0.6.8.4.1.0.0.2.ip6.int not found: 3(NXDOMAIN)

6.5.30m you say...
I'm running 6.5.30 f , in case that makes any difference?

I've already added IPv6-related in nsswitch.conf:

Code: Select all


ipnodes:                dns(ip6_rtld="ip6.arpa.") files

It looks like it's "sort of" working, but the reverse-IP6 lookup still doesn't.

nekonoko : I don't see a link to a patch somewhere in that thread? The thread involves a whole other issue where in older versions of IRIX they pointed to IP6.INT (which is deprecated by now) instead of IP6.ARPA. This is fixed in later versions of IRIX:

Code: Select all


speedo 7# strings /var/ns/lib/libns_dns.so | grep ip6


ip6.arpa.


ip6_rtld


speedo 8#

Infact, we're using IP6.ARPA already:

Code: Select all


speedo 11# host 2001:4860:a003::68


Host \[x20014860A00300000000000000000068/128].ip6.arpa not found: 1(FORMERR)


speedo 12#

I'm beginning to think the 'host' utility is broken? (FORMERR message seems obvious, = Format Error)
Any other ideas?

bplaa.yai : How did you set up you IPv6 that could differ from mine? Could you provide a 'cksum' of /usr/sbin/host?

Code: Select all


speedo 25# cksum /usr/sbin/host


3313214999 1299676 /usr/sbin/host


speedo 26#

I didn't setup anything special for ipv6. It's just a stock install in this regard.

We're indeed not using the same binary :

Code: Select all


julien@speedy > cksum /usr/sbin/host


442620923 1689916 /usr/sbin/host

That was more in reply to porter; as he's running 6.5.22 and it is known to be broken in that regard. You didn't indicate which version of IRIX you were using, so it was hard to say one way or another if that was something you needed to look at as well.

Ah. My mistake.
