Trek to Deo-Tibba Base - A Travelogue

Note: All images are available in the gallery.  Sorry, could not add links to the thumbnails.
Trek to Deo-Tibba Gallery

More than a month ago, from Aug 5th to Aug 13th, I went on a trek to Deo-Tibba base. The trek was good and it was the first time I went into the wild, away from the civilization. This is a small travelogue on the trek and hope it would be of some use to the future trekkers ;)
The medhas gallery has a more complete dump of the images that we took during the trek. All the images below have also been linked to their higher resolution versions from the gallery. Feel free to use the images that don’t have people in them for your own purposes. A link to our gallery would ofcourse be appreciated ;)
On Saturday, the 5th of August 2006, me and Bala started at Hyderabad and reached Delhi the same day by afternoon. We were joined by Metta and Gupta in Delhi and all four of us boarded the Himachal Pradesh Tourism operated bus to Manali the same day. We reached Manali on Sunday well before the lunch time, checked-in to the guest house and visited a few places in Manali. The photo above in which all of us are seen holding hands was taken when coming down from Hidimba temple in Manali. We met our trek operator Surinder (Alpine Tours) the same day.

Gupta, Metta and Bala at the Hidimba temple. Hidimba is a demon from Mahabharat, one of the epic stories of hindu religion. She is believed to be the mother of Ghototkachha and wife of Bhima.

We started our trek on Monday, with us were five porters, a guide and a cook (That’s right, seven people were with us and we were only four!). The itenary for the first day was to trek from Jagarsukh to Kannol. The govt of Himachal Pradesh is constructing a dam on Jagatsukh Nala and most of the work is currently at Kannol. A road is being constructed and the half done road is horrible to walk on - the mud was slippery and made it difficult to trek too! Kannol was the last place where we could find any significant human numbers. By the time we reached Kannol, it started raining too!

On our way to Kannol

First look at Kannol

Our tents at Kannol. Rain and worker camps made it difficult to find a proper place for camping here.

Tuesday we started at Kannol to Chikka. Due to all the construction that is going, the old trek route was closed and a new path was taken… this new path again had less grass and lose soil. The rain made it muddy and slippery too. Halfway through our journey on Tuesday we crossed the stream to join the old trek route, which made it feel like heaven. The first half of the way between Kannol and Chikka was slippery and a few slips could throw us into a stream 100 meters below.

Crossing to old route

This bridge marks the saperation between the new trekking route and the old. The real trek started here… we leave all the civilization behind at this place.

Chikka was a beautiful place located on the banks of Jagatsukh Nala. There is a small temple accompanied by a couple of small buildings. I will talk more about these buildings when I describe our journey back.

At Chikka

Our camp at Chikka

Bala and I had to use a different tent here because the tent we used in Kannol let some water seep in! And with this one I had a shock next morning when I saw a small creepy, caterpillar kind of an insect on my sleeping bag… eeks.

We started back early next day… it was raining and we put our umbrellas to use. The trek from Chikka to Seri was tiresome and we had to take many breaks for water and snacks before we reached Seri. Bala and I were a lot ahead of others and my research about Seri said that it was a huge plain land which would be of a great interest to flora enthusiasts - I was just walking and walking with a hope to find the huge plain land.

On our way to Seri

On our way to Seri

The trek from Chikka to Seri was at a much greater altitude, climate was cold and a significant part of the trek was through mist.

Camp at Seri

The huge plain at Seri

This plain was long time back a glacier which has now dissapeared. Going to the album you will find photos of the nearby glacier and snaps of the Deo Tibba peak as seen from the plains.

Waterfall and the Deotibba peak

Waterfall at Seri

The water fall is one big source of Jagatsukh nala, while the glacier pictured in other photos is the other source. Water from many peaks comes together just before falling down here. In the background is the Deo-Tibba peak.

The next day it was a looong trek. We were supposed to go till the Chota Chandertal and come back directly to Chikka, which was expected to take about 9 hours — yeah right, nine hours of trek in the mountains! We started fine, walking through the marchy football sized plain of Seri, but soon we reached a point where we had to cross the Jagatsukh Nala. I changed my definition of cold water after crossing the stream - we had to walk though a stream flowing at zero degrees! What more, we had to cross it twice in our route to Chota Chandertal and twice when returning!

The trek wonderfully well, till we found that we lost our way and instead of going to the Chota Chandertal lake, ended up going close to the Deo-Tibba base camp. We had to return due to lack of time. The photo here shows the joining of many small streams to form the Jagatsukh nala.

On our way back, we decided that we will not go by the same route. This time we had to go to Manali via Baraha, a small village close to Jagatsukh. We could find some accomodation at the temple buildings in Chikka. Our guide told us that the buildings here were constructed by the villagers of Jagatsukh for use by visitors to Chikka. It had all the required “comforts” like a room heater, food grain enough for about 200 people, bedding enough for about 30 people etc - and all this put in here by the villagers for the comfort of visitors, trekkers etc!

Next day, we trekked directly from Chikka to Jagatsukh, from where we went to our accomodation. One day more in Manali and started back to Hyderabad!

Quickest Microsoft Patch Ever

It took three days for Microsoft to release a patch to its DRM after a hacker developed an application called FairUse4WM that strips the copy protection from Windows Media DRM 10 and 11 files.

Compare this with “Patch Tuesday” - the second Tuesday of every month, the day on which Microsoft releases security and other patches to all its software.

Wired News: Quickest Patch Ever by Bruce Schneier:

If you really want to see Microsoft scramble to patch a hole in its software, don’t look to vulnerabilities that impact countless Internet Explorer users or give intruders control of thousands of Windows machines. Just crack Redmond’s DRM.

[...]

Since 2003, Microsoft’s strategy to balance these costs and benefits has been to batch patches: instead of issuing them one at a time, it’s been issuing them all together on the second Tuesday of each month. This decreases Microsoft’s development costs and increases the reliability of its patches.

The user pays for this strategy by remaining open to known vulnerabilities for up to a month. On the other hand, users benefit from a predictable schedule: Microsoft can test all the patches that are going out at the same time, which means that patches are more reliable and users are able to install them faster with more confidence.

[...]

Why? Because it makes near-term financial sense to Microsoft. The company is not a public charity, and if the internet suffers, or if computers are compromised en masse, the economic impact on Microsoft is still minimal.

Microsoft is in the business of making money, and keeping users secure by patching its software is only incidental to that goal.

Now, this [developing an application that strips the copy protection] isn’t a “vulnerability” in the normal sense of the word: digital rights management is not a feature that users want. Being able to remove copy protection is a good thing for some users, and completely irrelevant for everyone else. No user is ever going to say: “Oh no. I can now play the music I bought for my PC on my Mac. I must install a patch so I can’t do that anymore.”

[...]

This clearly demonstrates that economics is a much more powerful motivator than security.

[...]

It should surprise no one that the system didn’t stay patched for long. FairUse4WM 1.2 gets around Microsoft’s patch, and also circumvents the copy protection in Windows Media DRM 9 and 11beta2 files.

[...]

Certainly much less time than it will take Microsoft and the recording industry to realize they’re playing a losing game, and that trying to make digital files uncopyable is like trying to make water not wet.

Choosing the right MTA - Part 2

The following are two articles on LWN about the mail transfer agents.  The second would be available for free reading after September 7th, 2006.

A Comparision of Mail Transfer Agents  - Part I
A Comparision of Mail Transfer Agents - PartII

Choosing the right MTA

What are the general expectations from an MTA?

  1. Perform its primary task of sending mails. Should allow custom mail routes, sending via a SMTP server, envelope rewrite, virtual hosting.
  2. Allow interfacing with spam and anti-virus utilities
  3. Support authentication using the already existing authentication systems in my organization
  4. Efficient mail storage (mbox is obsolete)
  5. Support quotas
  6. Easy to configure, help the administrator avoid mistakes
  7. Performance and Security - most

Where do the existing MTA software stand?

  1. Sendmail does its primary task of sending mails very well - it is mature and has been adopted to almost all possible mailing situations. Supports authentication using SASL, which means that it can authenticate using many of the existing authentication mechanisms. Both spam detection software and anti-virus software are well integrated with sendmail, thanks to its milter interface. While all this makes sendmail a very good MTA, there is one thing that makes many of the above not easily usable - the difficulty in configuration. Its a nightmare to use all the features that sendmail supports and even for comparatively simple requirements, the configuration is vague and is a pain. Its bulky and is considered not very efficient too - the through put of other MTAs is reported better by many people. The difficulty in configuration adds to poor security awareness of many administrators, thus making sendmail a difficult choice in high-security environments.
  2. Postfix is considered the best alternative for Sendmail - it is commandline compatible with sendmail, has good number of mailing features and administrators very rarely need any features that are not supported by postfix that are supported by Sendmail. Postfix supports maildir format for more efficient mail storage and is also reported by many to have a comparitively better performance over Sendmail. Security is considered high, mostly because of the simple configuration files and less chance for administrators to commit mistakes. Authentication is supported via SASL.
  3. QMail is considered the most-secure and very efficient MTA, but it is low on features and distributions rarely come with qmail that can be run out of the box. Qmail needs administrators who not just can change the configuration files, but can also locate the required patches and compile the software. Even basic features like authentication, SMTP over SSL need patches and are not part of the base QMail. QMail has a very good record of large-scale installations. If you think you have an administrator who is motivated enough to find the patches and compile QMail to your requirements, go ahead with QMail. Also, make sure you read the QMail license which restricts re-distribution of binaries - thats the reason you wouldn’t find QMail in any of the linux distributions.
  4. Exim is again a sendmail alternative like Postfix. It has a good feature list and is easy to configure. Easy to extend and does not have a bad security history. Well documented too. Not very mature and not widely used on the Internet!

Sendmail is the MTA that I used and recommended, and after seeing that not many can configure and maintain sendmail (MTAs don’t generally need big configuration changes) I am in search for an alternative… for now its Postfix.

http://www.geocities.com/mailsoftware42/ has a very good evaluation of MTA software. Postfix and Exim have definitely improved a lot since then (Some of the features like IPv6 support in Postfix, mentioned as patches in this document are now into the original software)

http://zgp.org/linux-elitists/20020428173758.D31458@merlins.org.html has a good description of MTA software too.  This post also has some conclusions and the author prefers Exim and recommends Postfix to people who don’t need the extra features that Exim provides.

NetworkManager - Mobile Networking made Easy

NetworkManager:

Networking on Linux right now is painful for the mobile desktop user, especially in comparison to other operating systems. A laptop user should never need to use the command line or configuration files to manage their network; it should “Just Work” as automatically as possible and intrude as little as possible into the user’s workflow. NetworkManager attempts to make networking invisible. When moving into areas you’ve been before, NetworkManager automatically connects to the last network the user chose to connect to. Likewise, when back at the desk, NetworkManager will switch to the faster, more reliable wired network connection.

I always had a problem with switching networks between my workplace, friend’s flat and home… and the problem was even more severe when I visit other places!  After trying some scripting, I started search for network in synaptic to find this wonderful tool called NetworkManager!  Though the website does not give much information, try it and network switching would JUST WORK ;)

btw… this tool is well integrated with GNOME, KDE and XFCE systrays.

Google listed on SpamCop

Reverse DNS query from dnsstuff.comScreenshot of the query on spamcop.netSomething unusual came up today when one of my colleagues complained about mails from GMail not reaching him. The bounced message said “Mail from 66.249.92.170 not accepted - check www.spamcop.net/bl.shtml”. I just discovered that a block of google ips have been listed as spammers in the spamcop.net’s blacklist. Here are screenshots of aquery on spamcop database as well as the reverse dns query on dnsstuff.com.

Ubuntu: Derivative or Fork?

LXer: Ubuntu: derivative or fork?:

Ubuntu has something special that no other distribution ever had before. It shipped its own CDs to you, anywhere in the world for free. It has money (10 million USD from Mark Shuttleworth) and can afford that. For Linux newbies out there, Ubuntu is like Windows. In much the same way they have believed for years that Windows was included for free with their computers, they now have the same kind of facility with Ubuntu: they order CDs for free and it lands in their postal inbox. But much in the same way that they paid for Windows without knowing it, somebody has to pay for the free shipping.

Umm… just today when trying out the Ubuntu-6.06 (Breezy Badger) Server Edition, I felt that the server edition was nothing but some marketing shit!  Its a coincidence that I also stumbled upon this article when I was looking for howtos on creating a debian based distribution.

Economic Times article on OpenOffice.org

Goodbye MS Office, hello OpenOffice - The Economic Times:

OpenOffice, a multiplatform and multilingual office suite, gives users the chance to be Microsoft free — at last!

The Indian media has articles about free software — at last!  Media has always had something with Microsoft, everything that Microsoft does, including realeasing a toilet paper would be great news.  Gate’s visit to India would be on the first page… and in most cases you will need a mignifying glass to find news about a visit by Richard Stallman!

A similar article (very similar article) also featured on the Rediff a couple of days back.

Would love to see the media explain the philosophy behind the Free Software and the risks they are getting into by using non-standards complaint softwares like MS-Office.  I know, this is too much to ask ;)

Slashdot: Is Silicon Valley Reproducible?

Slashdot | Is Silicon Valley Reproducible?

“Paul Graham, in his latest essay, looks at the ingredients which make Silicon Valley what it is. From the essay: ‘Could you reproduce Silicon Valley elsewhere, or is there something unique about it? It wouldn’t be surprising if it were hard to reproduce in other countries, because you couldn’t reproduce it in most of the US, either. What does it take to make [a Silicon Valley]?’. In his opinion: ‘I think you only need two kinds of people to create a technology hub: rich people and nerds’. He concludes that if a city can attract these people, it can stand a chance of replicating Silicon Valley. What do you think of Paul’s opinions? If you would like some changes to the current Silicon Valley, what would those be?” While the people are an important part to the Silicon Valley experience, they are only part of the requirement. What local characteristics must also be present, even if Silicon Valley is to be duplicated on a smaller scale? What draws technology companies to a specific location?

Wanted to blog this, but got busy and was reminded of this slashdot discussion only after I saw a post on Rajan’s blog. This is the only article of Paul Graham that I read, and I liked it.  As always, the comments on slashdot make articles a more interesting read!
This slashdot discussion came up as a reaction to an article - “How to be a Silicon Valley” by Paul Graham.
