Creating a central syslog server

Your home network might already contain some devices or systems like a home server, a WiFi router, a media player, or home automation system. It is a best practice creating a central syslog server and storing logs of various sources in one place.

Update: The fail2ban and GeoIP related contents have been merged into post visualizing Fail2ban logs in Kibana.

This post will cover the basics. Creating a central log server and receiving logs from an OpenWRT device. Please note that you can do many more. See the other posts I created in this subject.

Docker failed to restart after upgrade

I already had plans to write about Docker. However a recent system update caused issues and Docker failed to restart. This service outage made me think and write about such a typical maintenance task.

Accessing media contents on TV

We already able to access our NFS exports on our Linux workstations or client machines. But how to access them on a TV?

There are two TVs in this article, one comes with an Ethernet connector and has DLNA functionality, while the other although also has “Smart TV” capability, but it is limited to a single USB storage device and does not support DLNA. Both of them are Samsung devices, but it does not really matter.

Let see how to access the media contents on them. I tell no lies, NFS will not play any role in it.

Mounting NFS exports by using autofs

When I created a central file sever, I mentioned that some of the problems with the solution are yet to be resolved.

autofs better than manual

  1. YaST created an import rule in file /etc/fstab, which is the de-facto place for storing such information. Its content and the mounts are usually static in server environments. On most client (in term of using an export of an NFS server) the network connectivity rarely or never changes in traditional environments.
    However in case of mobile devices like on laptops, the network state could vary a lot. It can be offline, or on WiFi, or on wired connection, maybe using VPNs. We need much more flexibility than a mostly static file.
  2. Users would like to mount exports on their own. The system should be as transparent as possible to the end users.

Lucky for us, mounting NFS exports by using autofs service help us and gives the following advantages too. Continue reading Mounting NFS exports by using autofs

Creating an NFS file server

In 2019 almost everyone has a digital life, so as I. Having digital photos or videos taken with our smartphones is an every day action.
Year by year the number of smart phones and computers rises in households. Files started to be found everywhere. In your computers, in the cloud, everywhere
Why do not we store them in one place and access them from everywhere?

I wanted to create a file server providing a central location for all our digital data. Creating an NFS file server looked promising.
