So! It’s been long since my last blog-post! But this one will compensate for the time I’ve been off-air.
Well, Logan‘s done a presentation on fq_codel and I got really interested in the topic. fq_codel (fair-queuing controlled delay), in a nutshell, was designed to overcome Bufferfloat; a phenomena in Networking whereby excess buffering of packets causes bottlenecks and thus reduces network quality. fq_codel is a scheduling algorithm that sets limits on delays suffered due to the bufferings. I won’t go too technical deep in this blog post.. This post will only show the setting-up of OpenWRT, and configuring it to enable CoDel and thus improve our networking performance. Hopefully, more posts about OpenWRT will follow including tutorials for some amazing features 🙂 Stay tuned !!
To be honest, I had some experience beforehand with those Operating Systems. I once got an Access Point from somebody that did not support bridge mode. I had to kick the propriety firmware out, install DDWRT, configure it (+ some tweaks 😛 ) and had it up and running. It’s still working since around a year or so..
The router I chose is a TPLINK WR841N; chose another model that had modem capabilities built-in but unfortunately, same did not support OpenWRT. Had to get it replaced by the vendor.
Well, let’s dive inside..
Following my past article entitled A short word about Linux, ideas were tossed on the Mauritius Internet Users mailing list about BSD having different approaches compared to Linux. The need for a BSD user group was voiced-out as well as raising the awareness on BSD and its advantages. Following that, a little chat with Logan again, who is also a BSD developer, brought out some fruitful information about BSD. Following is what I could extract from Logan 😛
Well, this will be a quick post but very important one.
Scrolling through my Facebook feeds, i stumbled across a post from a technology page regarding a vulnerability in some Wireless ASUS Router with USB network storage capabilities. The fact was that anybody could access the contents of the devices without passwords and without much efforts. From wedding pics, to music files to personal videos; everything! After some diving, i found that some people have already had their data stolen by some malicious guy asking for $50 to return the data.
More after the break line..
Imagine yourself in one of these situations; You are on the road, traffic jam and you badly need to connect to the Internet on your laptop… You are at home; there’s a power cut and you need an Internet Connection on your laptop but your router does not have backup battery.. How on Earth can you connect to the Internet ?? There exist Mobile Internet USB dongle, but the rains pouring outside, and you do not have a new SIM card to insert in the dongle. BUT !! You have a smartphone ! that already has a data plan or that can connect to the Internet and that very smartphone has a Wi-Fi antenna. Can you browse the Internet using your mobile phone as access point ?? Read on 😉
