I’ve been using VoIP (Voice over IP) for quite sometime now. I got fed up with the local telco offerings here in Canada, and decided to ditch them for VoIP.

This page will display the uptime of this Linux server and refresh every 5minutes. Uptime is the number of hours / days that a server is powered ON - no restarts, no reboots, no buts. For personal preference, a server with high uptime is just pure awesome! That means a sysadmin was able to maintain the system in tip-top shape without the need for a reboot! Or it could also be the reverse!

It’s been a while since I’ve added a new entry to this site, mainly because of the time I’m putting in reviewing for RHCSA. I’m almost done with one of the key areas of the exam, and there are 7 more to go!

I’d like to put a write up how I utilize VoIP for day to day communication needs.

I’m using Debian Linux and i3 window manager. Debian was a previous install on my main laptop while I was preparing for CompTIA Linux+ / LPIC-1. Debian grew on me and hadn’t had time to reformat to CentOS.

I do have several servers / VMs that are running on CentOS though. I experienced first-hand that there are several commands that behave differently in the CentOS / Debian world.

I really want to get this RHCSA over with. Gonna dedicate at least 2hrs everyday to practice and be RHCSA certified before my birthday kicks in! It is the best motivation for me, getting certified on my birthday!

I’ve integrated Google Analytics in my site, it’s a great piece of software that tracks and reports website traffic.

After 5 days of integrating it, I’d like to share some statistics. My favorite part of the report is the Sessions by Country, it lets me view where my visitors are from! Didn’t knew I have reached China and Singapore LOL!

This site now utilizes HTTPS! HTTPS is the secure version of HTTP, the ’S’ at the end of HTTPS stands for ‘Secure’. It means that the communication is encrypted.

Several things to make it work in my environment - edit hugo config file, create port forward rule in router, and finally configure HTTPS in Apache.

This will document the steps I did to be able to host a PXE server using CentOS and OpenWRT in my environment.

Requirements for PXE server -

• DHCP server to assign IP addresses
• TFTP server to host the pxe files
• FTP server to host the install files
