Learn IP Networking

by anil on July 6, 2008

I get emails from fresh computer science graduates on career guidance. Many of them want to enter the field of computer networking and security. So they ask me what should they do. Many of them have already done course like CCNA, RHCE, etc. hoping that those certifications would help them to start their career. To my surprise I understood that they successfully obtained their certification despite the fact that many of them don’t even know the basics of computer Networking.

If someone asks my opinion about joining such a course, I would discourage them, unless they know the fundamentals of computer networking. And I suggest them to go through their text books once gain before they spend money on any such course. Many of them asks me to suggest a list of things they are supposed to know to start a career in computer networking. This prompted me to compile a list of articles entirely from the Web which would enable a fresh-out-of-college to gain fair amount of knowledge to find an entry level job in this field.

Here is the list I prepared. Go through it and I am sure that you can start a career in computer networking with confidence once you finish it. All the best.

o Start your journey here [compnetworking.about.com].
This is a very good tutorial with a good breadth of coverage. This will help you understand the basic concepts and to build a vocabulary on the subject.

o Learn Linux. Linux is your best friend in understanding what really happens behind the scenes. I would recommend you to use a distribution like Debian Linux and not the ones like Ubuntu. If you use a Linux distribution with well-designed GUI such as Ubuntu, you will take longer to understand what you are actually doing. Once you learn what’s is happening behind, you can do the same on Windows and Ubuntu with insight.

This page [www.debian.org] will help you to get started with Debian Linux.

o Once you have learnt Linux, you start the real learning here [linux-ip.net]. Don’t get discouraged that this tutorial is too much Linux specific. You gotta learn some tools to learn hands-on Networking and I would say that Linux is the one of the best tools around. So go ahead and graduate in Linux Networking.

o Now you can move on to Windows. Windows too has got a bunch of useful command line tools. Start with them. This tutorial [commandwindows.com] will help you to get acquainted with those commands.

o Now you are familiar with basic Networking concepts, principles and tools. Now you can have a look at Windows Networking. I am sure that you will be able to look at the already-familiar mechanisms of Windows such as File Sharing and Firewalling with a deeper insight now. Read it here [compnetworking.about.com].

o Still most of the Network administrator jobs are in medium to large organizations running Microsoft Windows. I think now you have reached a position to design and implement a Windows Network. This Cisco Web page will help you to get started.

o Now, send me your résumé 🙂 You will get to know IP Networking inside out at Linuxense.

PS: Let me know if this list of URLs helped you improve your knowledge. More importantly, if you come across a useful URL, please forward it for inclusion here so that others too will be benefited.

May 1 Ride (2008)

by anil on May 5, 2008

[Correction 1: (corrected text in bold) … straight Highways and a deviation at any point towards the west will take you to some beach …]

[Correction 2: Thenmala is around 10Km ahead from the KTDC restaurant we had lunch at. This restaurant is exactly opposite to the Palaruvi road in NH208]

We at Silver Bullets have been consistently riding on all one-day holidays for the last one year. The latest in the series was May 1. One-day rides normally covers a round-about distance of around 300Km.

In Kerala you can choose to ride along the coast lines (straight Highways and a deviation at any point towards the east will take you to some beach) or through the eastern sides of Kerala which are full of twisties and hills. Most of the time we choose to ride through the eastern side called Western Ghats. This ride was no exception.

By Wednesday we kind of finalised the route: Trivandrum, Ayur, Anchal, Punalur, Achancoil, Shenkottai and decided to choose the return route along the way depending on the road conditions and mood.

There were not many takers for this trip. SB Trivandrum members were unusually busy with work/family this time. There were just me, Sankar (cutcrank) and Bala. But we had a few guests this time: my buddy Binuraj (who originally suggested the route), then Gokul and Shahu (both from Linuxense). Binuraj rides a Honda Unicorn. Gokul rides a brand new TVS Apache RTR 160 (who is running-in the engine as per the MotoTune theory and the reason for participating in this ride) and Shahu was pillion riding.

We gathered at Paruthipara at around 6:00am. Weather was cool and crisp and luckily the unexpected downpour prevailed since last week has stopped just the day before. So we had a very nice morning and we hit the MC Road by 6:30. This time too I was the sweep and cutcrank was the obvious choice to be the lead.

Ayur, the first deviation, was around 50Km from Trivandrum and then another 10Km to Anchal. We reached Anchal by 7:30am. Binuraj is a native of Anchal and we waited for him to join us. By that time cutcrank took out his Canon EOS400D and started flashing. Here is one pic from that lot (which I clicked): At Anchal

Our next destination was Punalur which is 12Km away from Anchal towards the East. We had a nice breakfast there and headed towards Achancoil. To those who are planning to venture this route: you need to take the Ranni route and take the road that goes to the right at around 4Km (the junction is called Alimukku). It’s very easy to miss this deviation; some of us did.

I used to accept hitchhike requests, when I’m riding, from locals if my luggage permits; especially from aged people. I kind of chat with them and get some geo/socio information from them. I found it interesting. This time too, I offered ride to an ammavan (uncle by age). But this time I was in a kind of trap.

As mentioned above, I missed the deviation at Alimukku. I was riding along the Ranni highway enjoying the scenery and the weather, one aged man in his 70s asked for a ride. I offered. As usual I started chatting with him and a few minutes later I explained where I’m heading. Then he realised that I’m a lost guy heading in a wrong direction! He said with exclamation that I lost my way. And the situation was more interesting because he was in trouble too: I either should get him back to the place where I picked him up or I should take him to the next point where he can get another ride (or catch a bus). I said to myself; well, I’m out here to ride and why not do a social service. And I decided to ride three more kilometres to the wrong direction and dropped him in a junction before I headed back.

That’s one of the good sides of motorcycling I enjoy. We can never do (or we don’t prefer to do) this if we are driving a car. With a motorcycle you are more free, more local and you can afford to show some random act of kindness.

Punalur Achancoil is the leg in which we leave civilisation and enter forest. Houses and grazing cattle begin to disappear and the green lush will get thicker. What you would notice while in a forest is the “deafening” silence. We stopped at several places to enjoy that and roamed around to get the feel of oxygen-rich unpolluted atmosphere.

In the forest

Achancoil is a township in the midst of the forest and at the border of Kerala and Tamil Nadu. People speak Malayalam there. I think they can speak Tamil too. We approached a local corner shop in Achancoil hoping to get some drink. We were totally tired by then. Bala was prudent enough to stock a few bottles of water but the terrain combined with this riding style made them pop out and fell down along the way; leaving all of us thirsty and tired. We found pre-packed sambharam in the corner shop. But that guy discouraged saying that that was not good (it may be of low quality butter milk prepared for local people for a cheap price) and offered Soda-Naranga Vellam (Neembu paani). Surprisingly he has got a Mr. Butlers Sodamaker in his shop and he prepared enough glasses of drinks for us in no time. We were recharged and ready to proceed to Shenkottai.

Riding through the forest

Achancoil–Shenkottai is more scenic. It has some excellent twisties for those who enjoy it. cutcrank and Binuraj were racing through the twisties pushing their bikes to the limits. And we reached Shenkottai by around 1:30pm. Our next priority was to find an eatery.

Shenkottai seemed deserted. May be because it was May 1. And we found it strange that we could not locate any restaurant. To add to the difficulty, majority of the team voted for a non-veg (read “mutton”) meal. So we checked with the locals for any “non-vegetarian” restaurants around. They said “yes” and pointed us to some direction. But, surprisingly, each time we landed in front of a vegetarian restaurant! Then we found out a small bug in our communication: the “non” in “non-vegetarian” was not understood by the locals and so it was ignored!

Gradually we realised that we were not going to get non-veg food in Shenkottai. The weather was gruelling; the temperature must be above 35 though humidity felt to be lower than that of Trivandrum. We decided to have some soft drink and head back to the Kerala border. Heading back to Kerala

For our return trip we decided to take the Ariankavu, Thenmala, Madathara, Nedumangadu, Trivandrum route. NH208 takes us from Shenkottai till Thenmala. NH was excellent till we cross the Kerala border. After Ariankavu it was totally broken. It was an acid test for the shocks and an endurance test for our body. At Thenmala we stopped at the KTDC restaurant for lunch (finally we found a place!).

But disappointing some of the ardent mutton fans in our team, they had only chicken in stock. But [luckly] our folks lost their ability to distinguish mutton from nicely prepared chicken. So they didn’t make much noise this time. We enjoyed homely meal there, took a 20-minute rest and we were ready for the last leg.

***

It was around 3:30pm when we started from Thenmala. There were around 80Km lying ahead to reach Trivandrum. We decided that there won’t be any scheduled stops hereafter and we would stop only on as-needed basis.

Kallada dam is located in Thenmala and it was visible from the road we took. We can ride over the dam. There weren’t much tourists there when we reached that spot. So we decided to have a stopover and take some snaps. Here are some: Kallada Dam. Bala riding down the dam: Bala

Binuraj said goodbye at Kulathupuzha (5Km down from Thenmala) and deviated to Anchal. From Kulathupuzha to Trivandrum, were almost solo riding. cutcrank and Gokul were riding ahead with considerable lead, followed by Bala and me.

We were safely back home by around 6pm covering around 300Km. Rough roads and lack of physical activities these days made us tired and caused some body aches here and there. But we were totally charged. I found a great way to fight the hang over: plan the next trip! Yeah, we are going to ride through Munnar soon!!!
