Hi,
nsd-4.0.0b5
after upgrading a host from Debian squeeze to wheezy I get tons of
$subject after the first query arrive (and no answer at all)
I assume I have to recompile. But there is no --disable-recvmmsg
Where should I start? Do you need more information about the host?
Thanks,
Andreas
nsd-4.0.0b5?
Latest version on/in Debian is 3.2.15-1

yes, it's BETA5 for nsd4
Hi Andreas,

This should be fixed in nsd trunk version - it checks at configure
time if recvmmsg is implemented.
Thanks, but it doesn't help (at least me).
I run the same package on different virtual machines. Both where upgrades von Squeeze to Wheezy.
But basicly it both Debian. One VM work, the other doesn't.

Hi Andreas,

Are you sure? Your output suggest vm1 is a Red Hat box.

I'm confused why the apparently identical binary works on the debian
machine. The man page states: "The recvmmsg() system call was added in
Linux 2.6.33. Support in glibc was added in version 2.12."
Did you really run ./configure on both VMs?

Yuri

I use virtual hosts from different (cheap) vhost providers for years.
The vhosts don't need an own kernel package and I didn't care about till now.
Looks like the hosts running the vhosts use different distos.
But that's the sense of virtualization and should not matter.
Did you really run ./configure on both VMs?
no.
I build Debian packages on a dedicated, external build host. But that host also run
Debian Wheezy. Doing so was never a problem last years.
NSD4 uses kernel? features. Availability is checked at build time and that looks wrong here.
It should be possible to select at run time.
For now I try to disable HAVE_RECVMMSG in config.h ...

patch (ugly) attached
NSD should not really detect the system at runtime; it is built by the
packager. But, an option to make the build compatible with older
Linux kernels is good, and I added this to the NSD4 source.
The attached patch for NSD4(beta5) adds a configure time option
that --disable-recvmmsg for compat with older Linux kernels,
by default it autodetects support in the kernel on the buildmachine.

right.

The patch modify configure.ac. But my buildsystem just uses configure
and ignore the changed configure.ac.
I'm not the expert to modify configure itself.
