Syslog and SIGHUP on FreeBSD

Unbound
1

Hello unbound-users,

I'm using unbound on FreeBSD with syslog from FreeBSD ports. Query logs were
written in it when I started unbound first, but unbound didn't write any query
logs in it after I sent HUP to unbound with kill command. Unbound just wrote
"Restart of unbound 1.1.1.", never logs were written then.

I looked over some source files and found that unbound wrote query logs to
syslog when closelog() in util/log.c was commented out, but I don't know why
it did so. I don't have confidence whether this is correct. Does anyone solve
the same problem without touching source codes, or does this problem depend on
FreeBSD?

Thanks.

Hi Atsushi,

A fix is in svn trunk for unbound.

It no longer re-opens syslog, only if it logged to file does it reopen
the file to facilitate log rotation.

This makes it easier to deploy unbound. Previously, unbound needed a
dev/log link into the chroot environment.

Best regards,

I've just added the patch to the port.

Hi Wouter and Sergey,

Thank you for your fixing.

I tried your patch from FreeBSD port. It works fine!
Thank you for your helping!
