yum keeps its own history, so you can find out when a package was installed or updated using its history. For instance, yum history packages-info ruby will give you all the transactions involving ruby, where the oldest one is usually the one where the package was installed. Transaction ID : 102 Begin time : Thu Apr 3 17:15:17 2014 Package : ...

Fedora 21 and RHEL/CentOS 7 use the new Python-based postgrey reimplementation. In this implementation the only change you need in your Postfix configuration is to call the service from smtpd_recipient_restrictions. For instance, taken from my own mail server: smtpd_recipient_restrictions = #.....other stuff here # This should be ...

The rich rules aren't necessary at all. If you want to restrict a zone to a specific set of IPs, simply define those IPs as sources for the zone itself (and remove any interface definition that may be present, as they override source IPs). You probably don't want to do this to the "public" zone, though, since that's semantically meant for public facing ...

...I eventually figured out that the file ownership and permissions details have changed. And, I made a small error in the configuration files, too. As many software packages do, the new scheme installs with examples that include many comments and commented out lines that prompt you to get the configuration you want. However, there was no line like this in ...

What I had installed is listed in the question above. However, I did a yum list clamav-* and found there were packages available I did not have installed, including a milter, among other things. ...

I'm not sure about the firewalld command to do so, but you can change the zone in the ifcfg files in /etc/sysconfig/network-scripts — edit ifcfg-enp2s0 and ifcfg-enp5s4 and add ZONE=external and ZONE=internal, respectively.

I'd use OpenVPN. Either put the VPS on the same OpenVPN instance you're using for remote access, or create a new OpenVPN server instance for VPSes. I do the latter to connect a slew of cheap test VPSes around the world back into my home network. The client export config archive option makes it easy to configure the VPS side.

It turns out that after much gnashing of teeth, I noticed that there's a package I had installed that NOBODY had referenced so far as I had ever seen. It's called spamass-milter-root. So, after having checked EVERYTHING I could think of, I figured, why not? ... ("#" is the system root account's CLI prompt.) # systemctl enable spamass-milter-root.service ...

When I have experienced this it was because of SELinux getting in the way. To test if this is your problem, simply turn off - or change to non-enforcing - the SELinux software. To do this, edit /etc/selinux/config and set SELINUX to either permissive or disabled. If changing to permissive, restart SELinux with systemctl status selinux.service. If turning ...
