Citeren Roger Price <[email protected]>:
I added [::1] to the upsd line in /etc/hosts.allow
upsd : 10.0.0/24, localhost, LOCAL, 127.0.0.1, [::1] : ALLOW
and then ran command "rcupsd restart" to restart NUT.
The latter is a waste of effort. This is not how tcp-wrappers works.
[...]
The man page for upsmon.conf currently says for the MONITOR directive:
MONITOR system powervalue username password type
Each UPS that you need to be monitor should have a MONITOR line.
Not all of these need supply power to the system that is running
upsmon. You may monitor other systems if you want to be able to
send notifications about status changes on them.
You must have at least one MONITOR directive in this file.
system is a UPS identifier. It is in this form:
<upsname>[@<hostname>[:<port>]] The default hostname is "localhost".
Perhaps it would be worthwhile adding the following note to this description
Note. The hostname "localhost" you specify here cannot be relied on
as the only possible hostname in access control file hosts.allow.
You may also need to specify other possible identities for local
system, for example "upsd : localhost, LOCAL, 127.0.0.1, [::1] :
ALLOW". See also hosts_access(5) and hosts_options(5).
The SEE ALSO for upsmon.conf refers to upsmon(8), upsd(8),
nutupsdrv(8). I suggest adding hosts_access(5), hosts_options(5) and
maybe tcpd(8).
This has nothing to do with upsmon(.conf). The connection is rejected
by the upsd server. In the upsd(8) man page there is already a
reference to hosts_access(5). Sadly this isn't very specific about
systems running both IPv4 and IPv6 at the same time.
The hosts_options(5) and tcpd(8) provide no useful information for
people setting up NUT with tcp-wrappers. The problem you're seeing
here is common for applications that use tcp-wrappers and really
should be fixed by packagers (by adding a line to the /etc/hosts.allow
file).
