Internet is the most important and one of the basic amenities in today’s world. Sharing internet using WiFi router with slow speeds having low bandwidth is a real pain. Plus if you end up working from home and taking Skype for Business (formerly Lync) calls then you’ll be virtually fighting with your kids & wife. They’ll be using the same internet to browse youtube, shopping sites etc which are bandwidth hungry apps.
I was aware of Squid proxy but never explored it to use it for throttling bandwidth for clients. I followed this guide to install squid on my Raspberry Pi and modified configuration file according to my requirements. Below is the configuration file of squid proxy which will throttle the internet speed / bandwidth for the clients like laptop, android phones and tablets.

I’ve highlighted important lines in RED color above. I’ve created an acl called “clientpc” for the local network having IP address starting from 192.168.2.90 to .100. Created a default pool ‘1’ and class ‘1’. ‘delay_parameters’ for pool ‘1’ set to 64000 bytes (512KB). We can increase or decrease depending on the internet speed or bandwidth.
Enabled proxy in firefox. If you’re in stone age and still use ‘IE’ then go search for ‘proxy settings for IE’ in search engines 😛
- Click the Firefox menu. Select Options from the submenu.
- Open the Advanced category. It is on the right end of the category list. …
- Click the Settings button. This will open the Connection Settings window.
- Choose “Manual proxy configuration”. …
- Enter your proxy information.
Enabled proxy on the android phones and tablets by referring to this link.
Tested internet speed via speedof.me Below screenshot shows that the download speed was successfully throttled by Squid whereas my internet connection speed is 2 Mbps. Now I can work from home with peace of mind and grabbing a largest piece of “internet” pie.
It was time consuming and eaten up my Sunday but worth to spend the time as I don’t have to crib in future about internet speed or poor voice / audio issues.

Packagekitd daemon was using high memory usage on the Debian Linux server. Almost 30% of the total RAM!!
Tried to identify the root cause but didn’t help. so I had to kill the process to avoid further issues on the server.
“BOSS (Bharat Operating System Solutions) GNU/Linux distribution developed by C-DAC (Centre for Development of Advanced Computing) derived from Debian for enhancing the use of Free/ Open Source Software throughout India.The Beta Release of BOSS GNU/Linux Version 5.0 is coupled with GNOME Desktop Environment with wide Indian language support & packages, relevant for use in the Government domain.

I’ve copied above contents from BOSS Linux site. In this blog I’ve shared the screenshots of installation which exactly resembles typical Debian OS install. My base OS is Debian 8 🙂 I’ve tried BOSS on Oracle Virtualbox.
I’ve downloaded the ISO image of BOSS Linux v.6 from this link
Below screenshot shows the Oracle Virtualbox console. I’ve clicked on “New” and named the Virtual Machine (VM) as BossLinux, Type as Linux and Version as Other Linux(64 bit)
I’ve selected Country as India and selected keyboard layout as “US English”Given host name as ‘boss’ and default values are selected through out rest of installation steps of partitioning the disk. After disk partitioning, installation of system started and completed successfully. Selected GRUB as boot loader and installed it on /dev/sda1 partition (Infact we created only 1 partition)Login Screen looks stunning!! BTW BOSS Linux logo or moscot is very similar to Apple MAC… may be I could be wrong 🙂Desktop looks awesome, well placed BOSS banner. A typical GNOME desktop with nice wallpaper! As we can see Network Manager and PulseAudio are already installed as part of OS installation.
Most of the packages installed are generally available in other distros expect for the two packages ‘Boss Bulk Document Converter’ and ‘Boss Presentation Tool’ which are included as part of office suite apps.As mentioned in the beginning of the blog, Indian language packs are pre-installed and ready to use. Below screenshot shows a document with Kannada along with a simple to use / refer on-screen keyboard ‘EazyKeyboard’. Similarly other languages are also available
I hope this could come in handy while you use / refer this blog for exploring this Indian made OS derived from Debian OS. Thanks for reading and follow my blog for regular updates.
