Farewell Speech (Tech Issues)

Below is the soft copy of my farewell speech on tech issues.

Good evening everyone. Carry forward the legacy left by one of our seniors, I am going to narrate a short story.

There was a boy, by name OMI, who came to IIIT without having any background in computers. He used to spend all this time in workspace exploring Linux usually at the cost of missing his lectures and even meals. Inspired by the works done by Nirnimesh, SMR etc., over a period of two years, after struggling, only as he could have done, he climbed onto the post which he always wanted, the sysadmin of IIIT.

Today I would like to speak about a few topics. The first one among them is my experiences as a sysadmin.

Our network is not ready to take the ever increasing load. The old wifi infrastructure has already crossed its End Of Life period. Also, the network is not properly planned which increases the time required to solve the issues. For example, it took several days to fix the network loop problems in different research centers last year.
Though we use open source to cut down our IT budget, we don’t make the best use of it.
The process of getting things done is slow. For example, we have not been able to narrow down on buying a firewall since last six months.
Now coming to the people part of it, the server room staff is generally co-operative but the problem lies with the administration mostly because of the slow decision making.
Within the administration, there is lot of interference by the people who don’t have adequate background in related fields.
Most of the time server room staff do the work they should not like asset management. Why a person who spent all his life in exploring technology should count number of computers in your lab?

Now, I’ll talk about the changes I tried to bring about and problems I faced.
There has always been an invisible gap between students and server room server room administration. It wasn’t very easy to convince people to stop treating the other end as enemy.
It was my top priority to restore the faith of administration in students so that more students can be brought into administration process.
Different research centers manage their own servers which poses a great difficulty for the server room staff to assist them. Everybody having their own network eventually increases the security loopholes as well. We tried to reduce the decentralization. Research centers are not usually ready to give up the rights easily but slowly things are changing and we have already moved few servers back to server room.
Since our network is growing, the policies that have been in place for past few years are becoming obsolete. We are in process of revisiting the different policies.

I’ll conclude by mentioning few key points. We urgently need to renovate the existing infrastructure otherwise there will be chaos. There is a need to invest more funds in IT infrastructure as its the backbone of the institute and it should not be seen as a burden. Gear up the approval process. We should be more transparent with students while forming the new policies.

I would like to thank IIIT for giving the students an opportunity to be involved in system administration and I hope the future batches will take this up as a serious job.

Thank You!

Mumbai Trip and First Time Flying Experience

As I said in my previous post, I was asked to visit Rediff Office in Mumbai. I thought Wednesday (25th) would be a great idea. Informed the same to HR. I got the return ticket to Mumbai on Tuesday. This was the first time I was going to Mumbai and also the first time I was boarding a flight. Both flights were Indian Airlines.

To Mumbai

Took Aero-Express from Hitech City to Airport. I was at airport (Shamshabad) at 6:15AM. Flight was a 7:50AM. So there was a lot of time that I could waste on the airport. With no idea how to proceed, I kept following a co-passenger (from the bus) and ended up in a queue for international flights 😛 Security redirected me to entrance for domestic flights. I proceeded to check in counters following a very simple approach. Look for counters with hot girls 😛 Among those, look for a counter with smallest number of people in the queue 😀 And it worked out of the box. Got the tickets. Moved in for security check. It was hassle free as I didn’t have any luggage. It was still an hour for the flight to take off. Used the free internet for few minutes. I was a bit nervous 🙂 About half an hour later, we were asked to proceed for boarding.

Ten minutes later, I was in plane. It was Airbus A320. Luckily I got the window seat. I was surprised as there was no in-flight entertainment system and the airbus looked technologically challenged 🙂 Few minutes later, the plane started crawling. It kept crawling at the same speed (20-30 km/hr) for so long that I got extremely frustrated. I was thinking, “Abe Mumbai paidal lekar jayega kya??” (Are we going to Mumbai by foot). I breathe a sigh of relief when it started accelerating. It was a thrilling experience after that long boredom. Things I imagined while playing NFS and other car games suddenly became live. We were on the ground at almost 300km/hr. The feeling while the plane takes off is damn nice. You feel something in the chest for sometime. After the plane is completely in air, things again become boring as the plane looks static with respect to ground. I was feeling like, “Why the hell its not moving??”. As the charm of flying for the first time was over, I picked up the newspaper. It was business line. Couldn’t really figure out a story to read. Then I picked the Air India magazine. While I was turning the pages, saw Katrina on sidebar of a page. Continued reading the story and figured out that both Airbus A319 and Airbus A321 have in flight entertainment systems. It was a real bad feeling to get stuck into A320 when both A319 and A321 were awesome 😐 The food served in breakfast was pretty good. Few minutes later, it was announced that we were in Mumbai. Landing in Mumbai was awesome. Actually, the planes first goes into the sea and then take a U turn. The landing experience was also awesome. It feels great when the plane decelerates.

To Rediff Office (Mahim)

I was warned by Sachin about the taxi drivers charging huge fare for no reasons. So I was a bit careful. But still ended up paying twice the actual charge. I left the airport at around 9:40AM. It was damn hot there at that time. My destination was Rediff office which is located somewhere in Mahim(West). Airport to Bandra (Western Express Highway) was totally jam packed. Taxi wallah turned out to be a bit smart and took the service root and managed to save a lot of time. Still it took almost an hour to reach the office.

In Rediff Office

I met Sumit in the office. He introduced me to a lot other people in NOC team. A small HR interview was conducted which was a surprising element for me as I never expected something like that. But it was fun talking to people from HR department. Then I met Sachin there. He introduced me to a lot other people related to domains I like. After that I had a small chit-chat session with managers from the NOC dept. After that Sachin introduced me to CTO, Rediff. We had a long chat session (almost half an hour). We talked about a lot of things in different domains (mainly open source). After that inspiring chat session, Sachin and me went out for lunch. I felt good to see good north Indian food nearby. We returned to office. Few minutes later, Sachin introduced me to CEO and CFO, Rediff. After that I had a long chat with Sachin about company environment and work culture.

Keeping in mind the traffic conditions, I left for the airport at 4:30PM. Unfortunately/fortunately I didn’t encounter any traffic and reached the airport at 5:00PM which was like 2 hours before the flight. To fight boredom, I headed over to Kingfisher check-in counters and found out a place to sit optimizing the view 😛

To Hyderabad

I was in plane at around 6:50PM. A321 looked really advanced as compared to A320. We were on the runway at scheduled time. But on the way it halted and waited there for another 20 minutes. By the time the plane took off, it was 25-30 minutes late. This time also I got the window seat. BTW plane was almost empty (only 40% of the seats were occupied). We were above sea in a few minutes. The view of the city in night from the sea was beyond my imagination. Every single light adding to the beauty of it. The view was best when the plane took a U turn. The entire Mumbai was visible and lights increased the beauty exponentially. The highways looked like long chains of light sources intersecting each other. It was a really wonderful experience. As we left Mumbai, the in-flight entertainment system was activated. I was browsing the channels and found one of them playing “Sorry Bhai”, one of my favorite pass-time bollywood flick. We reached Hyderabad at around 8:40PM. Took Aero-Express back to Gachibowli.

All in all it was an awesome trip to Rediff Office and also a wonderful first time flying experience 🙂

Rediff Interview

A few days back I got a call from an alumnus about a job opening at Rediff in my domain (server side craziness :P). Initially I was a bit surprised because I was not expecting something like that at all. After discussing a bit more about it, I returned to my room and forwarded the resume. Two days later while I was in RnD Showcase, I got a call from Rediff regarding the interview timings. It was scheduled on Saturday 21st at 1PM.

Saturday 21st

In the morning at around 9:40AM, I got a call from Sumit Rajwade (VP, Tech, Rediff) asking if interview can be conducted at 10:30AM. I replied positively. I got a bit nervous as I had to quickly arrange a place where we can meet. Arranged a conference room. At around 10:15AM, I got another call from Sumit saying that he was at coffee shop. I was deeply shocked. Coffee Shop :O I couldn’t really figure out what was going on. In my point of view, coffee shop is THE best place in IIIT Hyderabad. For me its a holy place 😛 When I reached coffee shop, I saw two guyz enjoying cold milk. Sumit said, “Whenever I come to IIIT, I always visit coffee shop. I can’t miss this cold milk”. I was still dumbstruck.

After brief introductions, interview started. He asked some NATing questions seeking answers at TCP level. I was able to answer those. Then we moved on to open source domain. Talked about Apache compression and keepalive for sometime. Then we moved on to squid and caching. I feel so good when somebody asks me something about caching/squid. Have been experimenting with caching/squid since last 1 year. Then we exchanged a few thoughts about our interests. Luckily there were no questions about printf statements. Then I briefed him about things I have been doing since last four years. After that he introduced me to the kind of work they are expecting from me. It looked pretty awesome and inspiring at the same time. Few more thoughts exchanged and it was all done. I was asked to take some time out to visit Rediff Head Office in Mumbai.

All in all, it was fun talking to Sumit. He has been hacking (here hacking means hacking and not cracking) open source softwares since years. Inspiring personality.

The most shocking thing to me was the coffee shop part of it. I never imagined that I’ll be interviewed at Coffee Shop.

To be or not to be Marcus Cocoza

The feeling that B.Tech. is almost over forces me to feel a bit nervous. I spend (I am not sure whether to call it wastage) a lot of time socializing (at coffee shop and in BC with friends) and rest of the time I am sitting in front of my computer screen trying to develop or explore something. My life at IIIT has been influenced by a lot of factors from Dr. Kamal‘s use of a tablet pc and wifi to connect to the projector for a lecture or Dr. Sangal‘s outstanding way of teaching or the limited bandwidth forcing me to think of alternatives or Nirnimesh‘s inclination towards Linux or Ranta‘s entrepreneurial skills or Sandeep Saini‘s dedication towards downloading. You have so many people around you with exceptional skills in their fields. All these have forced me rethink about myself in one or the other way.

Today there was a mail on squid development mailing list with a link to this page. I was pissed off by the C++ code on the page. At one time I was very good at C/C++ but python killed the interest and knowledge over time. I was strongly inclined towards OOP back then. When I saw the above page today, I felt an inclination towards C++ yet another time. Well, thats me. Just think about something and start doing it without thinking what would be the result. I picked up “The C++ Programming Language” by “Bjarne Stroustrup” from the cupboard and started turning pages. While doing that the page after the Introduction caught my attention. There was a long quote. I generally don’t read stuff like this but I felt some urge to read it. It was

… and you, Marcus, have given me many things; now I shall give you this good advice. Be many people. Give up the game of being always Marcus Cocoza. You have worried too much about Marcus Cocoza, so that you have been really his slave and prisoner. You have not done anything without first considering how it would affect Marcus Cocoza’s happiness and prestige. You were always much afraid that Marcus might do a stupid thing, or be bored. What would it really have mattered? All over the world people are doing stupid things… I should like you to be easy, your little heart to be light again. You must from now, be more than one, many people, as many as you can think of…

— Karen Blixen (writing under the pseudonym “Isak Dinesin”),
from “The Dreamers”, from “Seven Gothic Tales”.

It was a wonderful reading. Inspiring enough to force me to blog about it. Looking forward for reading a bit about C++ also and becoming a squid developer from a squid plugin developer 🙂

The best new year gift

We just received a mail from IIIT-H help desk stating

New year special proxy server has been created for all users as gift from
IIIT Server Room staff. There are no moderations done on that proxy so all
websites are accessible. Even better there is no connection limit per IP
or per user on the new proxy.

Proxy is accessible at IP _SNIP_ on port _SNIP_. Please feel free to
download as much as you want from this new proxy server.

Merry Christmas and Happy New Year!

Regards,
IIIT Systems Help Desk

Probably the best gift I have ever received.

I announce cachevideos.com ( the official guide for caching videos )

I still remember when I launched saini.co.in in November last year. That was my first website that I owned and I came to know about things like hosting, domains and related things. This year, I am proudly launching cachevideos.com, which will act as an official website for my (now) popular squid plugin youtube cache. The website is drupal based and all I have done is populated the content, modified some CSS, installed some modules, themes etc. It took almost 1-2 days for building that website. Drupal is a real cool CMS if you want to build sites quickly. Will write a post about how I build that site sometime. A big thanks to Sambhav Jain for customizing the header image for the website using photoshop. And train loadz of thanks to SMR for providing fu**ing awesome hosting service at g33k.in. Will write a review about the hosting sometime soon.

My addiction for purchasing domain names is growing with time. I currently own 10+ domains just for the heck of it. Wasted (invested?) more than $100 in last one year on purchasing domains. I own the following domains currently.

Hopefully I’ll stop purchasing domains and start working on putting content on them 🙂

Exams Over and Upgraded to WordPress 2.6.2

Finally the exams are over for the 20th time ever since I joined IIIT. 20 times in just 3 years is a bit too much of evaluation and still there is not even single person in my batch who can really be evaluated based on his/her scores in these so called exams. More than 80% of janta spend 6-7hours per course per semester other than attending classes which anyway doesn’t count. And a BIG THANKS to the 20% of janta for studying damn seriously and teaching creatures like me 😛

Also, upgraded to wordpress 2.6.2 to be on the technology front-end. Previous version was giving some problems with image uploads and it was an irritating experience using elinks and stuff to upload image files.

A visit to Dr. Reddy’s Labs

Yesterday, a team for five (four people from administration and me) visited Dr. Reddy’s Labs in Hyderabad for a live demo of two security products Linkproof and DefensePro from Radware. DefensePro is a firewall kind of thing (for lay man) which protects your critical servers and Intranet from internal as well as external attacks. Linkproof is a load balancer for outbound as well as inbound traffic in case of multiple (<= 3) ISPs. Linkproof also manages traffic in case one of the ISP fails.

We reached their office at around 2:40PM. The office looked just like another office of some IT company. Fully loaded with sensors. You need not push/pull the door when you enter the office. And everything that an enterprise office should have.

A few minutes later, one of the person from Radware accompanied us to their technical wing called “Information Systems”. Their we had a demo of both the products on consoles. Demo went on for almost half an hour. After the demo we asked if we can see the actual hardware they have deployed. Then the admin in DRL (Dr. Reddy’s Labs) accompanied us to their DMZ (DeMilitarized Zone, its a common term in security industry. Denotes a place where all your critical servers are placed. A highly secured zone basically). I was amazed by the hardware that I saw. I just can’t express my feelings. Though we were not allowed to enter the rooms but everything was visible through the glasses. Rack mountable servers everywhere. Racks, racks, racks and more racks. Awesome experience. I wanted to stay there forever and keep looking at the beasts but …

We headed back to IIIT after that. And yesterday night, in my dreams I saw I own a server farm which had uncountable racks of servers. Racks everywhere 🙂

PS : The above two products will be deployed soon in IIIT for testing purpose 😀

Three days with Fluctuating Internet

We had three days with totally fluctuating internet. The fluctuation was almost like a sine wave. Nobody could really figure out what went wrong and where the problem was.

NOTE : This post is not just another ‘masalla’ post. I am writing down the actual experience I had.

DAY 1 : August 26

All this started on August 26th sometime in the early morning hours when browsing speeds and the bandwidth usage touched the lowest levels in the last month. As I keep monitoring the bandwidth usage (bandwidth monitoring and download progress bars appeal me somehow for certain unknown reasons. I keep looking at progress bars when I download something. I just get lost in kind of dreamworld while looking at them.), I was surprised to see the low usage because everyone was in the campus and usage should touch the peak levels. It returned to normal after a short period of time and browsing was normal. But this pattern kept repeating itself. I went to attend the class. I returned at 11:30AM and rushed to server room to checkout whats going on. By that time server room was swamped by the phone calls from different research centers.

Nobody was actually able to figure out what was going on. All that we knew was that there was heavy broadcast from a segment on the network. We suspected it as the same problem which we faced last week. But isolating the problematic area is heck of a job and nobody was ready to check the network devices at the leaf level because of following reasons (1) It’ll take almost a day to check individual NIC in all the labs, (2) There is no security that problem will be resolved.

We took a tough decision of shutting down the network in entire problematic segment. This worked and network was fine. No fluctuations. But it proved out to be a wrong decision. We didn’t inform the people in the affected network (which unfortunately consisted of major research centers at IIIT i.e. CVIT, CDE, CVEST, LTRC (temp) etc.) and immediately we had to face the phone calls from HODs. One thing that I learnt from this situation is that Internet connectivity is equally important for everyone at IIIT including faculty members. Though we keep blaming students for being addicted to internet. Internet here is not an addiction, its a need. We had to re-up the network. And the rest of the network started fluctuating again. Everybody left for lunch.

As the time passed, the frustration among the users grew and everybody was almost shouting. Everybody wanted to know why its was taking so long to solve this problem. After lunch one of the admins went to the problematic area and started debugging at the individual switch level. But he faced a real tough time as most of the switches at leaf level are unmanageable (you can’t see any error reports unless you plug into individual switch). And we have a lot of switches (by a lot I mean a real lot of switches). And the switches are cascaded in such a dangerous manner that isolating a problem becomes way difficult. By evening that day we could isolate two research labs and three other segments which were generating heavy broadcast. We shut them off and everybody left for the day. There was a kind of blackout in those segments. No internet, no LAN.

During the night, I kept monitoring the network. A lot of people pinged and complained about the DNS resolution problem. Web pages were loading at a high speed but the name resolution was taking a lot of time. I tried looking at the logs and the traffic. Everything was fine except that the nameserver was swamped by the mail servers for name resolution. I tried a few hacks but nothing worked.

DAY 2 : August 27

I didn’t have any class that day. Admin XYZ called me at around 10:30AM and requested to come to server room if possible. I was sleeping and I hardly wake up at that time. But I didn’t want to miss the opportunity. Got up quickly and rushed to server room wasting as least time as possible. I was in server room at 11:00AM.

Admins suspected some problem with proxy as the fluctuation persisted even after cutting off the problematic areas. By the time I reached server, admins switched over to the stand by proxy machine. And to get started from Zero, entire network except the main building was shut down. We waited for almost half an hour. Everything worked absolutely fine. No fluctuations at all. So, main building is fine.

At around 11:40AM, network was restored in all the hostels. We waited for another half an hour. No fluctuation yet. But hell lot of phone calls sensitizing the situation. Everybody including seniors members rushing to server room. We suspected some attacks from hostels on the server in labs. But we were wrong. The problem is in the library building. But where?

Till lunch time, no network in areas except main building and hostels. As the time passed, the issue became more and more serious. It became difficult to answer phone calls from senior members as the word “Heavy Broadcast” now became irritating for them. They were listening to this since last two days. But nobody actually knew the exact answer. The origin of the broadcast was still not known.

Admin XYZ rushed to the library switch. Now XYZ was in live contact with admin PQR in server room and restoring the network in research centers one by one. Restore network in one research center, wait for half an hour. If no fluctuation, proceed otherwise revert back. Using this technique (this was the only solution), we restored network in all the centers except two. Connections to these centers also cascade to other areas. Complete outage in the two research centers. Everybody left for the day, leaving the two research centers in dark.

Network stabilized a bit. And fluctuation was not frequent (almost none). I monitored the network up to 2AM. Didn’t sleep because had a class at 8:30AM.

DAY 3 : August 28

I had a class up to 10AM. Rushed directly to server room after the class. We already narrowed down to a smaller region. Now the problem was smaller and there were lesser number of people after us. Admin ABC with a student was sent down to inspect individual switches. Thats the problem with unmanageable switches. You have to go and check each and every switch for any error messages. Anyway we kept narrowing down the problematic area till lunch. I left for lunch and returned to my room as I didn’t sleep during previous night. I don’t know what happened in the afternoon. I missed that 🙁 At 6:30PM, I called admin XYZ and asked about the status. He informed that the problem has been isolated. Only two very small labs were left.

Three days and problem was still there. People were really out of control. Anyway network worked perfectly in other areas except those two labs. The good thing was that these labs were at the leaf level and they were not cascading connections further.

DAY 4 : August 29

I had a lab from 10AM-11AM. But it went up to 11:45AM. By the time, I reached server room, the problem was already resolved. Everyone was connected and no more complaints. Rawat sir updated me with a few decisions which are beyond the scope of this post. The problem was the routing queries from one of the ISPs connected to those labs at leaf level.

It really took almost four days to debug this problem. Debugging a network, especially debugging a network which is randomly cascaded, has more than one entry points, has no perimeter and has a lot of unmanageable switch is a real challenge.

Anyways it was again a learning experience for me. I used to blame people for not able to solve the network problems quickly. I just realized that its very easy to blame.

PS : Longest post on the occasion of bloggers’ day 🙂

Freaking 50 hours

All this started after returning from dinner at around 8:00PM on August 19.

August 19 – 08:30PM – 10:30PM : Slept.

I woke up at 10:30PM and started browsing random stuff. Gave a finishing touch to GSoC project – IntelligentMirror and announced the release for testing.

August 19 – 10:30PM – 12:30PM : Browsing + Blogging + Browsing.

After that its time for some refreshments.

August 20 – 12:30PM – 02:00AM : Snacks + Toasts.

Then started the same old thing. Browsing. Why the heck we have to browse all the stuff in this world which has no meaning 😐 Also, I had to prepare for my presentation about SMTP protocol in Topics of Information Security class. So, downloaded all the RFCs (thats what we do all the time. download all the academic stuff and feel good about it. Who has time to open and read them 😛 ). Read a bit of stuff from the RFCs.

August 20 – 02:00AM – 07:00AM : Browsing + Reading RFCs + Browsing.

If you are up till 7AM, breakfast is worth a try. Had a breakfast which was good eventually.

August 20 – 07:30AM – 08:00AM : Breakfast.

After that, I though I would go to bed and will sleep for sometime. But then Internet is a real devil which will not let you sleep. Started browsing again and checking everyone’s status message. Reading blogs and some more blah blah. For god sake, don’t put links like this in your status messages.

August 20 – 08:30AM – 12:30PM : Browsing + Fantastic Contraption + Browsing

If you are up till 12:30PM, its good to have lunch before you go to bed 😀

August 20 – 12:30PM – 01:30PM : Lunch.

After lunch, I was desperate to sleep. But then I had this class called “Music Appreciation” at 5PM. I was afraid of losing an attendance and didn’t sleep. I read RFCs in the meantime. No browsing this time 😀

August 20 – 02:00PM – 04:30PM : Reading RFCs. No bc.

At around 4:45PM we rushed to coffee shop and then to class. After reaching the class, we realized that prof will not turn up and class stands canceled.

August 20 – 04:30PM – 05:20PM : Coffee shop + Class.

While returning from class, I just wanted to visit server room to see whats going on (actually the network was fluctuating really badly and just wanted to know what exactly is going on. I am a student sysadmin, so kinda concerned about these issues). But I came to know, some serious problem has occurred due to real heavy broadcast from few research labs. Sysadmins were zeroing on the problem. I suddenly forgot about sleeping and all. There may not be a better opportunity to learn how to configure a switch and how to debug a network problem. I was lost somewhere in the switches and servers and I realized it was 7:00 by the time admins sorted out the problem.

August 20 – 05:30PM – 07:00PM : Server room (real good experience. Learnt a bit about how to configure switches 😀 )

By the time, I left server room it was almost 7:30PM. So just rushed to Yuktahaar to have food. Had some good food. Yuktahaar is probably the only mess in the campus where you can actually eat something.

August 20 – 07:30PM – 08:00PM : Dinner.

As I had to give the presentation on SMTP the next morning, thought of reading some more stuff quickly. Read up to 9:00PM. At this time, I was *REAL* desperate to go to bed. But at about 9:19PM, Himank called up and told about bloggers meet. I was like WTF. Well I wanted to attend the meeting and rushed to main building. Meeting went upto 10:30PM. The meeting was real fun and it was a good experience to meet all the bloggers from my batch. We decided few things to promote blogging in IIIT. Find the details in the link in next line.

August 20 – 08:30PM – 10:30PM : Reading RFCs + Bloggers Meet.

After returning from the meeting, I though of finishing the RFCs and preparing the presentation. But RFCs was a lot more than I assumed, so reading went upto 1:30AM. Prepared the presentation.

August 20 – 10:30PM – 01:30AM : Reading RFCs + Preparing presentation.

I was about to sleep and suddenly Rishabh appeared and now there is something with proxy 🙁 We discussed about the proxy and other misconfigurations for almost 1 hour.

August 21 – 01:30AM – 02:30AM : Discussion about proxy.

I went to bed at 2:30AM. Felt a bit relaxed. But couldn’t sleep. Why?? I was feeling hungry 🙁 Get up at 2:45AM and rushed to Deepak’s room for having some snacks.

August 21 – 02:30AM – 03:00AM : Snacks + Toasts.

I was in my room at 3:00AM trying to analyze the situation. “If I go to bed now, I’ll not be able to wake up for 8:30AM class and the whole idea of preparing the presentation will be wasted. Should I sleep or not??” Went to bed but got up again in 15 minutes thinking that its impossible to wake up for the class(lack of confidence??). Browsed stuff for sometime and then had a look at the servers. And this time mailman was not working on the students server. Mails to students mailing list was not being delivered. Tried to debug that for almost 2 hours, but all in vain. Monitored servers for sometime and some more browsing. Please forgive me for sending all the test mails 🙂

August 21 – 03:00AM – 06:30AM : Mailman debugging + Server monitoring + Browsing.

By 6:30AM, I was like “I’ll die if I don’t sleep. But if I sleep, I’ll miss the class. WTF :(( “. I finally decided to sleep. But scheduled alarms at full volume on my computer. Scheduled high beat songs(shell scripting rocks 😀 ). And decided to sleep on the chair itself as its difficult to get out of bed.

August 21 – 06:30AM – 07:45AM : Sleeping (on chair 🙁 )

Woke up at 7:45AM and rushed to mess at around 8:00AM.

August 21 – 08:00AM – 08:20AM : Breakfast. OBH mess serves the worst breakfast you can have. They server chowmin in breakfast. I AM NOT KIDDING.

Now starts the actual hectic session. Continuous class upto 1:00PM. whoaaaa!!!!!

I would have gone to room for sleeping now. But mailman is still not working and students are missing their mails 🙁 Went back to server room. Did ad-hoc management to bypass mailman for temporary mail delivery. Fixed few other things.

Enough is enough. I *MUST* sleep now. Returned to room quickly ignoring the dinner and went to bed thinking that I’ll sleep for at least 14-16 hours (normally I sleep for 12-14hours at a stretch). But who knew that its not possible. I wake up at 12:30.

Woke up at 12:30AM. And Internet is here again. Browsing. Browsing. Browsing. Browsing. Browsing. And blogging. BTW, a newer version of youtube cache is available now.

Browsing again. And I have been writing this god damn post since half an hour. Its almost 3:30AM now and I am thinking of going to bed again. Hopefully I’ll sleep well this time 😀

August 22 – 02:30AM – 03:30AM : Blogging.

Previous two days was really hectic. No? Well, I can’t really take more than that. I think my biological clocks are out of synch. Need a break.

PS1 : Change your status messages frequently. Don’t bore me.

PS2 : Need to blog more frequently. Have a lot of stuff to blog about. This sem is real happening.

PS3 : Have two courses on security this sem. Wish me luck 😀
