Dirk, are you able to reproduce? It's working for me.

Sebastian, please, could you set DEFAULT_LOGGING to "yes" in /etc/sysconfig/autofs, restart the automounter, reproduce the problem and attach the logs from /var/log/messages here? Also, I'd like to see the contents of /etc/sysconfig/autofs.

Thanks.

verbose debugging gives:

I should add here that bridge.fresse.org is an IPv6 node.

> Sebastian, please, could you set DEFAULT_LOGGING to "yes" in

Sorry, I meant "debug" and not "yes" above.

I can reproduce the problem here, AutoFS doesn't seem to work with IPv6 servers. However, the original version from 11.4 (5.0.5-14.17.1) also doesn't work for me. This makes me wonder if it's the same problem.

IIRC, to use IPv6 with AutoFS, it needs to be linked against libtirpc (and on 11.4 it isn't).

Please, could you attach debug logs from the version that works and also from the version that fails? Thanks.

I guess I'm a div.

Whereas on a x86_64 it's broken with 5.0.5-14.17.1 too, so I guess you're using the 64b version as well.

    The TAB here ^^^ shouldn't cause any trouble, but since it's the only difference I could spot so far, could you replace it with a space and check if it still fails?

Negative, still fails.

Could you please attach /proc/mounts from the machine that works, after the volume was mounted? Thanks.

While we figure out what's needed to make this work on 11.4, you can use the packages available in the filesystems repository:

  http://download.opensuse.org/repositories/filesystems/openSUSE_11.4/

These should work.

I still can't understand how this works on klang :/

When I query the AAAA records from bridge.fresse.org on DNS, it returns two addresses: 2a01:198:5b7:200::1 and 2001:470:9141:200::1. Is it possible that the first works while the second doesn't?

The AutoFS maintenance update released for 11.4 includes some patches that could have caused the behavior change:

  * use weight only for server selection
  * mount using address for DNS round robin host names

2a01:198:5b7:200::1 and 2001:470:9141:200::1 are the same machine, and they both work.  Like I said, the 14.17.1 works on 32bit 11.4 but *NOT* on 64bit 11.4.

> Like I said, the 14.17.1 works on 32bit 11.4 but *NOT* on 64bit 11.4.

Yes, I understood that. I even installed a 32bit 11.4 here to test and confirmed that both versions do not work :(

Please, could you capture the network traffic between the server and klang with both versions (14.17.1 and 14.19.1)?

I will, but I will have to reproduce a klang-like machine because klang is actually a production machine and can't be used for debugging.

Sebastian, I'm preparing the AutoFS update for openSUSE 11.4. This update will include several bug fixes from upstream and one important change: automount will be linked against libtirpc. This is necessary to fix this bug and to make AutoFS behave better on IPv6 environments.

I'd appreciate if you could try the packages that are now available in:

http://download.opensuse.org/repositories/home:/leonardocf:/branches:/openSUSE:/11.4:/Update:/Test/standard/


... and report whether it works well on your environment. Thanks!

Works like a charm!
Thanks heaps for that.

Cool, thanks for testing! I've submitted this to 11.4:Update:Test and I'm now waiting for it to be accepted.

Now released in the updates repository (autofs-5.0.5-14.21.1).
