If you are using OpenDKIM behind a restrictive network that doesn’t allow all outgoing UDP connections, you may find some issues when checking authoritative responses for public keys:
key retrieval failed (s=20120113, d=gmail.com): '20120113._domainkey.gmail.com' query timed out
key retrieval failed (s=20120113, d=gmail.com): '20120113._domainkey.gmail.com' unexpected reply class/type (-1/-1)
The workaround is to set static DNS servers (whatever is allowed in your network) in /etc/opendkim.conf using the directive Nameservers:
In order to enable NFS auto-discovery, open Zabbix’s interface, go to “Administration” -> “General” -> “Regular Expressions” -> “File systems for discovery” and add “NFS” to the regular expression.
Depending on the interval defined on the discovery rule, it may take some time for the partitions to show up.
So, your newly configured service doesn’t work properly whenever you have SELinux enabled… Instead of just disabling it, try one of the proper ways to fix it:
– Reproduce your problem so fresh logs are generated.
grep denied /var/log/audit/audit.log > /tmp/denied_stuff.log
– Check and confirm the content of the log.
cat /tmp/denied_stuff.log | audit2allow -M service_please_do_this
– Check and confirm the policies in the file “service_please_do_this.te”
semodule -i service_please_do_this.pp
