Transcending the Value of 8layer Job Orientation

It’s the time when students line-up, submit their application and find a company for their respective OJT subject.

With too many IT students looking for a haven where they can find relevant learning, prepare them for the real world and take a step into the practice of professionalism, 8layer finds it hard to trim down candidates and accept only a few.

This summer, we got our room and hands full with about 10 Job Trainees from PUP Sta Mesa, AMA, TIP and Divine Word College of Calapan, Mindoro and plunge into the 8layer Job Experience encapsulated in 250 hours or so.
But before they get started in getting their hands dirty with hardware and network nitty-gritty, minds boggled with programming and agile framework concepts and firmed to enhance confidence in public speaking, each individual must go through the 8layer Orientation.

Aside from merely introducing our company; people, process, rationale and culture plus our special way of welcoming newcomers, we regard the Job Orientation as a major element of becoming part of the team to make sure that each one is aligned to understanding what it is to become an 8lien.

Operation Occupy 8OHQ

On March 28, 2012, more than 50 4th Year Computer Engineering Students from the Queen City of the South invaded the 8layer Orange Headquarters(8OHQ) as part of their Seminar and Field Trip subject.

They are the enthusiastic and future IT practitioners and professionals from the University of San Carlos, Cebu City.  This was the same time that most of us were just coming back from the Intel Negosyantech Event (Legaspi Leg) so it was Dondi and Jasper’s turn to walk them through KahelOS for these students to have a hands on experience with Linux and Open Source.
Part of their objective was to have a feel and sense of how an Open Source IT Company runs and operates and basically what are the services that 8layer offers.

The Cebuanos came at around 10:30 in the morning, toured the office, listened and participated to the seminar especially prepared for them for two hours. Before they left with the 8layer Experience on our community projects, advocacy and work, they also got home with them KahelOS CD Installers for them to tinker and play around.

This year marks 8layer’s 7th Anniversary.  Last April 2 at the 8OHQ, Team 8liens gathered to celebrate our togetherness through thick and thin as we pursue our simple whims to provide affordable, reliable and easy to use applications for the Filipinos.
It was a really pleasant, meaningful and joyous anniversary bonding that started at merienda through dinner. #8liensunite. Padayon at ipagpatuloy ang ningas ng ating samahan at pinagsasamahan.

Here are some of 8layertech Milestones.
 - As part of our advocacy, we co-launched the release of the New KahelOS Version

Neighbour table overflow

After implementing a network gateway and firewall server solution to one of our clients having 500+ users, we encountered “Neighbour table overflow” error upon checking of the server logs.

This is the command to view server logs:

$sudo tail -f /var/log/messages

Mar 30 10:39:25 www kernel: Neighbour table overflow. Mar 30 10:39:30 www kernel: printk: 7 messages suppressed. Mar 30 10:39:30 www kernel: Neighbour table overflow. Mar 30 10:39:36 www kernel: printk: 4 messages suppressed. Mar 30 10:39:36 www kernel: Neighbour table overflow. Mar 30 10:39:40 www kernel: printk: 10 messages suppressed. Mar 30 10:39:40 www kernel: Neighbour table overflow. Mar 30 10:39:45 www kernel: printk: 12 messages suppressed. Mar 30 10:39:45 www kernel: Neighbour table overflow. Mar 30 10:39:50 www kernel: printk: 24 messages suppressed. Mar 30 10:39:50 www kernel: Neighbour table overflow. 

This message indicates that the server is too busy processing some firewall rulesets.

The immediate and rational solution that we opted is to increase the internal ARP cache size of the server and DNS threshold for ARP.

At the console, edit sysctl.conf

$sudo vi /etc/sysctl.conf

Append the following values:

# Force gc to clean-up quickly
net.ipv4.neigh.default.gc_interval = 3600
# Set ARP cache entry timeout
net.ipv4.neigh.default.gc_stale_time = 3600
# Setup DNS threshold for arp
net.ipv4.neigh.default.gc_thresh3 = 4096
net.ipv4.neigh.default.gc_thresh2 = 2048
net.ipv4.neigh.default.gc_thresh1 = 1024

To make sure that the solution is working, load the new changes using sysctl command.

$sudo sysctl -p

Upon several tests, the solution proved to work.
