[freetds] IPv6 support?

[Dick Visser]

Hi everyone

I am currently deploying MS SQL Server 2008R2, which is running on an
IPv6-only system.
This seems to work OK (i.e. server can be managed and SQL server can be used).
We are mostly a Linux shop, and thus have set-up our monitoring with
Nagios on Ubuntu.
I would like to use this Nagios plugin:

http://labs.consol.de/nagios/check_mssql_health/

That is written in Perl, using DBI, which uses DBD::Sybase, which in
turn uses FreeTDS, which does not (yet) support IPv6.

Would it be possible to add support for IPv6?

Many thanks!

Are you asking if anybody is willing to write support for IPv6 or if
we are happy you provide a patch for IPv6 and are you asking if we are
going to accept it? Well.. yes, we accept patches!

If you search on internet for "patch IPv6" there are quite a few.
Personally I'd use getaddrinfo/getnameinfo and write portable wrapper
if not available.

Yep, I'm working on a new IPv6 patch.

Thanks to Peter now we support IPv6 !!

Perhaps patch require some additional tweak but mainly for platforms
that does not support IPv6.

Our test suite is happy and no leaks are detected.

I am successfully using it to monitor my IPv6-only SQL2008R2 box using
Nagios :-)

This is a great step.
Since Microsoft has very good support for IPv6, the number of
Microsoft servers that run IPv6 will only increase.
The FreeTDS library now enables many applications to use SQL Server
instances on such servers.

Many thanks!!!
