Hi, I used to build from source, but for our CentOS 7 and 8 servers I have been using the Terabithia RPMs with no problems. The downside is that, like Malcolm Hunter mentioned, I have subsequently applied some local patches - sent to the list - so that meant rebuilding the RPMs. I would say if you use the stock code, then the RPMs are trivial to install rather than building from source. If you have local mods then it's up to you - build from source or rebuild the RPMs. Either way you have to rebuild something :-) At the moment I'm keeping an eye on the 'Terabithia RPMs still active?' thread, since it may of course mean reverting to building from source. Although the question may be modified to how much is the source on sourceforge being updated anyway?

I used to build my own RPM, but Terabithia is so easy, I just use it.

So now you've got me interested. I'm not thrilled with devmon, but it mostly gets done what I need. What does the built in SNMP do for me? Where do I find out more about it?

We've been using Terabithia for quite a while. We pull the repositories down into our Satellite server and it makes for easy install and deployment across our organization. I wish he could get the packages added to EPEL, but pulling from Terabithia has been working just fine.

Really? I've just run a test on a local server, and neither chronyd was disabled nor was ntpd installed. after installing xymon, chronyd kept running as it was before, and the ntpd package was not present before or afterwards.

I downloaded the source rpm and installed it. The spec file for building
the RPMs contains this:
%if %{without trunk}
%if 0%{?rhel} <= 7
Requires: ntp
%endif
%endif
So, yeah, it builds into the binary RPMs the requirement to pull in ntp.
I'm not sure if that can be made into a conditional, to require ntp OR
chrony.

I think there's an historical reason for the ntp package being required.
The xymonnet binary uses ntpdate (via NTPDATE defined in xymonserver.cfg)
to be able to monitor the "ntp" service. Specifically it execs "ntpdate -u
-q -p 1 <host IP>". The code in do_net.c is written around the output of
ntpdate, so chronyc couldn't be used as an alternative without some
serious munging of the output. So for a base Xymon server deployment,
ntpdate is generally required. [Actually, Xymon can use sntp instead of
ntpdate, but this isn't actually relevant to the current situation.]
I seem to recall, on earlier (prior to v6) versions of RHEL, that the
ntpdate binary used to be part of the ntp (or xntp or xntpd) package. This
is probably where the dependency on "ntp" came from.
Installing (the package) ntp also brings in ntpdate (as a prerequisite),
but installing just ntpdate should not install ntp. This seems to be the
case for RHELv7 and v6. I'd say the spec file should match %{?rhel} between
6 and 7 and do "Requires: ntpdate".

Looks like ntpdate and options are defined in ~/lib/environ.c and ref. in the ~/xymonet/xymonnet.c and ~/xymond/rrd/do_net.c code. Looks like something that needs to be updated, as I'm running a dev xymon server on CentOS 8 and the ntp rpm's are not part of the distro anymore. Dave

When we went for CentOS 8, we simply took the CentOS 7 source RPMs for ntp and rebuilt them for CentOS 8. There are good reasons why you would want to choose NTP over Chrony in certain corner cases. Mark

It is true that ntp/ntpdate are not part of RHEL 8 at all. Has anyone gotten it working with the Terabitha RPMs on RHEL 8 yet? Sounds like there are code changes that are needed to make the 'ntp' checks work correctly, beyond just changing the RPM spec? Thanks! -- Matt Vander Werf
