[Ilugc] IR Receiver that works on Linux for an XBMC HTPC
Hello, everyone, I'm looking to buy an IR receiver that works easily on Linux. I know that it's possible to build one, but I'm really short on time here (I'm leaving for elsewhere soon and I want to make a HTPC for my parents/brother). Also, how does this sort of thing work? I have a Radioshack Universal Remote. Does the receiver need to be built for a specific remote or will it pick up the stuff and do the mapping from button-press-received to keypress in software? In the latter case, I can probably have the Radioshack remote configured correctly rather easily. The less complicated, the better. Any help is appreciated. What I've found so far is that lots of TV tuner cards come with an IR remote and a receiver. However, no one seems to post on the Internet about whether the remote and receiver work with the card or just the TV-tuner part. I could probably pick up an Intex TV Tuner card and try to get it to work, but I haven't used a TV Tuner on Linux in years (last was a couple of years ago with bttv and a Pinnacle PCTV 50i Pro, I think) and don't really know how these things work. By the way, I'm thinking of running XBMC because it looks way better. The output will be an ancient CRT TV for now, but my brother can probably work things out once I have everything set up so that if they buy a newer LCD TV, things will be fine. Any opinions on that are welcome as well. I have little experience with this, but hopefully things will go smoothly.

I remember using `namebench` to find a fast DNS server when the Airtel servers were (predictably) being terribly slow. If you're looking for a way to do what you want, that's a good place to start. It's unlikely that _every_ DNS server (and there are many) that `namebench` has in `/etc/namebench/hostname_reference.cfg` has been attacked so they're likely to return different addresses. There's the usual caveat that one domain can still point to multiple addresses but you can probably still exhaust all the alternatives by trying them enough times. Of course if you are even worried that your ISP's DNS servers have been poisoned just switch to using Google Public DNS or something and avoid the problem. Having those attacked in a way that allows someone to lose something is likely to cause such a huge fuss that you'll definitely notice.

[Ilugc] The right way to set permissions for an Apache Virtual Host
Hello, Is there a 'correct' way to set permissions on /var/www/example.com such that I can have a specific user write to that folder, and have apache use it for the Virtual Host example.com? I am running Apache 2.2 on Debian 5 (Lenny). While searching for a solution, the only relevant result I've found is <http://serverfault.com/questions/6895/whats-the-best-way-of-handling-permissions-for-apache2s-user-www-data-in-var> but that is from 2009 and I don't know if there's a better way now. Here's a summary of what I've gathered is a way to do this (but I'm not just trying it out because I don't want to create a hole that I forget to fix while undoing everything): 1. Create a new group `www-examplecom` and add the users `example-editor` and `www-data` to it. The former is the regular user I want to have access to the files for that Virtual Host and the latter is the Apache user which may need to upload files using PHP. 2. Change ownership of `/var/www/example.com` to `root:www-examplecom` 3. Change permissions of `/var/www/example.com` directory (and subdirectories) to 0775 to give owner and group read/write/execute and then to 2775 to set SetGID to ensure files created under `/var/www/example.com` are created under `www-examplecom` 4. Change permissions of files under `/var/www/example.com` to 0664 to read/write for users. 5. Change umask for user `example-editor` to 0002 so that files are created by him in a way that allows them to be edited by the group as well. 6. Set umask in the PHP program to 0002 so that files are created by user `www-data` in a way that allows them to be edited by the group as well. You might wonder why I need to give `example-editor` access to this host. Quite simply, I have a friend who I agreed to host and I need him to be able to write to this folder on his own. However, I don't want him doing something foolish and killing us all, so I can't just give him the root password. Is this the right way to go about things?

Let us see if we can work it out. First of all, resolution works in the opposite way to what you seem to believe. You resolve a domain name to an IP address. I will attempt to restate your problem and you can say if that is right. Then we can attempt to solve it. You have a domain name (example.com) and two subdomains on it (a.example.com and b.example.com). You want the following to happen: 1. When a user attempts to access a.example.com and b.example.com from a LAN that you control, you want them to go to 192.168.1.2 and 192.168.1.3 respectively. 2. When a user attempts to access a.example.com or b.example.com from outside your LAN, you want them to go to 203.0.113.1 (assume this to be the WAN IP of your server) Is this what you want to do? Well, the question is, where is the nameserver for example.com? If you want the same nameserver to serve up different records based on the origin network of the request, then using split-horizon will work fine. However, if you have one nameserver on the Internet (say your host provides one) that already resolves example.com and subdomains to 203.0.113.1, then let that be. Run a nameserver on your local network, add a zone to it each for a.example.com and b.example.com and give them A records pointing to 192.168.1.2 and 192.168.1.3 respectively. Also, you might want to check with the network admins at IITM. They have some solution for the problem since ftp.iitm.ac.in resolves to different addresses depending on the origin network of the request.

I forwarded your instructions (with the modification to unlock the root account) to the tech support team at my provider soon after receiving them but power failed in the middle of the night here so I was unable to reply. I'm told they're attempting to see what fsck is complaining about now. As for how this happened, I don't really have an explanation. I originally intended for this server to be where I test ways of doing things but as time passed I started using it for more than I should have. To top it all off, I moved from an older unsupported Ubuntu to the newest release because they pulled the repositories, and so some of my files were stored _only_ on what this server until I got a git pull off. Locking the root user was one of these things I was trying out. You see, Ubuntu runs by default in the following configuration: 1. One or more `admin` users who get elevated privileges using `sudo` by virtue of being in that group. 2. One `root` user who can't be logged into but with whose privileges you can run using `sudo`. 3. In the event of going into single-user mode it will drop you at a root prompt. There was no real reason to lock root, seeing as `sshd` has PermitRootLogin set to no. I did it at the time to see if I could emulate Ubuntu's behaviour. One of the first things I should've checked was whether dropping into single-user mode worked. Ridiculous, I know.

[Ilugc] Locked Root password, Debian 5 refuses to go into single user mode
Hello, I've got a terrible problem. After reading up on `sudo` and looking at archived emails on [debian-user], I came to the conclusion that a nice way of having multiple admins on my server is to use `sudo` to give them powers and then lock the root user. Unfortunately, on Debian this leads to a deadly situation. In the event of a failed fsck, Debian gives you the bog standard, "Enter root password to continue (or press Ctrl-D)" message. The problem is that the root user is locked. There is simply no password. `Ctrl-D` just restarts the OS. To make it worse, this computer is a VPS running on VMWare, hundreds of kilometres from me. The set up being fairly unusual, the sysadmins aren't sure what to do. They can get to the bootloader, but can't mount the drive elsewhere (limitation of the VMDK format) or do anything of that sort. Any advice would be appreciated. I'm having that horrible sinking feeling right now. Regards, -- Roshan George ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

All the solutions on the Internet use synclient. The problem with this is that synclient needs to be run at boot, after waking from suspend, and after logging in. Occasionally, it will stop working and require a reboot before it starts. Any advice would be helpful. I remember there being a gconf entry in some earlier release that allowed me to switch back to more usable settings but it seems to be missing. I'm beginning to regret upgrading, but I had no choice: they removed the old repositories. Regards, Roshan ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

What are the pros > and cons of moving to 64 bit? I've been running a pure 64-bit Ubuntu 9.04 since the time it's been released. At the time, I saw a marginal increase in ffmpeg encoding videos and an actual slight decrease in mencoder. This might be an issue with w64codecs, but I'm not sure. For most usage, the difference was really small. Performance advantages are tiny, so you probably shouldn't change just for that reason. You can even stick to 32-bit with the PAE kernel if you want to address more RAM or get NX-bit support. The repositories are nearly the same size. I haven't had trouble finding any software I need and I've installed quite a few packages (`dpkg --get-selections | wc -l` reports 1965 packages). I don't have Flash installed, but I did install it on a friend's 64-bit install. They have an experimental version that works fine. If you have proprietary graphics hardware, you still shouldn't be worried if it's mainstream. I have installed both nvidia's drivers as well as ati's fglrx with no trouble. There are minor quirks with both where suspend will work imperfectly on some hardware, though. If you're planning on installing 3rd party proprietary software, you might be in for a bit of trouble, though. Some games I remember trying didn't even release 64-bit versions, though IIRC, you could do something by jumping through hoops and installing the equivalent of ia32-libs for your distribution. Essentially, the long and short of it is that upgrading lost me nothing and gained me precious little. Do it if you feel like it.

While the RAM usage wouldn't show up under Buffers/Cache, it did drop to expected use as soon as I required the extra RAM (by mallocing up a few megabytes). I assume this is how this hypervisor (the vmware one, I think) works. Since I have since not noticed any performance issues any more, I think what I was experiencing was unrelated and so I've decided to just let things be. This is how things worked. `free` would report > 900 MB of RAM after subtracting buffers/cache but when I ate up that last 100 MB or so, `free` would report ~ 300 MB which is much closer to what I'd expect.

At the moment, I'm not seeing any trouble, but last night there was this short period when the server started swapping and performance was terrible. It would take ages to even serve a static webpage. I sorted the entries in `top` by memory and on top was mysqld (125 MB VIRT, 17 MB RES) followed by a few 4 MB apache processes. Even adding up the VIRT table (the highest values) comes to a number about a fourth of the RAM use reported by `free -m`. -- Roshan George ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
[Ilugc] Identifying the source of high memory usage
Hello, everyone, I'm running Debian 4.0 on a VPS. Yesterday, I had this problem where more than two-thirds the available RAM was taken without any programs running. RAM use was at around 700 MB _after subtracting cache/buffers_ but adding up the memory use of all the processes in `ps aux` would only reach about 150 MB at maximum. Is it possible that a program I was running earlier had memory leaks? If so, how would I go about fixing this without rebooting the server and how can I identify which program exactly is causing this? I have the source for none of the likely culprits.

Hi, Raja, I should say that it worked itself out. I suspended my laptop and when I later woke it up it connected to the wireless network and I had Internet access. Strange, eh?

Here's the thing. The Airtel tech set it up like this so I can't explain why it is the following way, but anyway here you go: Modem: 192.168.1.1 (if I connect to it directly with cable) Router: 192.168.1.1 (if I connect to it over wireless) My laptop: 192.168.1.2 (on both Windows and Ubuntu) Another laptop: 192.168.1.4 A desktop: 192.168.1.7 The last two are Windows-only. As you can see, I'm unable to access the modem while connected to the router. Thank you for your help. Unfortunately, I'm not about to change anything now that it is all working.

[Ilugc] Strange problem connecting to the Internet
Hello, everyone, I have a wireless router (it also has a modem inside) to get my Airtel internet connection. Generally, my computer connects to the wireless network and I browse. Recently, though, I was forced to get a modem and connect that to one of the wireless router's ports because the modem part of the router wasn't working very well. Now, I can connect to the wireless router from any computer but I can only access the Internet from Windows computers. Pinging any outside address from a Linux computer results in a 'Destination Net Unreachable' error. The very same computer will then connect to the very same wireless network when in Windows and browse (and ping) just fine. I can access other computers within the network when I'm on Linux. I just can't access the Internet. I've done the following so far: 1. Ask dhclient to get a new lease. 2. Deleted the network settings and then entered them again. 3. Rebooted (ha ha) Funnily enough, when I use the inbuilt modem in the router again it works just fine. Any advice would be appreciated.

Firstly, if you're using it for this purpose then you needn't worry at all. A difference in longitude from 80.23° to 80.234° is a difference in terms of surface distance of a few nanometres at most. Hardly a problem for weather. Secondly and more importantly, you're asking for the impossible. The floating point data type can only represent a fraction of all rational numbers accurately. This is not a limitation of the language you're choosing, it is a limitation of the format. -- Roshan George ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Well, I meant something like using 8000 and 23 instead of 80 and 0.23. Then when the time comes to print your number you can just do something like: a = str(8000+23) b = a[:-2] + '.' + a[-2:] Your output will be the nice 80.23 that you always wanted. Unless you're doing some division that requires you to hold on to the third place or lower, why use floats when integers will do the job? -- Roshan George ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

The number 80.23 cannot be represented exactly. Use the decimal module if you want exact numbers: <http://docs.python.org/library/decimal.html>. For more information look at the Python Docs on floating point: <http://docs.python.org/tutorial/floatingpoint.html>. As you'll see there, Python 3.1 will print the result in the way you want, but if you want more accurate arithmetic, multiply all your numbers by 100 and use integers instead or use the decimal module. -- Roshan George ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

I saved maybe 40 ms every request over Google's DNS so it was completely unnoticeable. Both Google's DNS and a caching name server (on the same LAN) were huge improvements over Airtel's stuff but the difference between the two was usually unnoticeable. With Airtel's DNS I would frequently be looking at time-outs quite frequently and when I wasn't the results were slow. -- Roshan George ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Hi, Arun, I might have access to a Pinnacle PCTV Pro PCI card (bt878 chipset, I believe). I gave it to a friend because I wasn't using it, but I don't think he is either. If this is not particularly urgent, then I can send this to you sometime in August when both my friend and I will be back in Chennai. I'm not sure if it is still available from retailers, but you'll find it in abundance in second-hand markets.

[Ilugc] Filtering specific languages (particularly Tamil) in Gmail

Oh, this seems rather easy. Here's what you have to do: 1. Login to your Gmail account from your desktop 2. On the right of the search box there's a link saying 'Create a filter'. Click it. 3. Now, among the boxes there, there's one labelled 'Subject'. In that box type 'க' (no quote marks). For another language you'll probably want a letter that is common in that language. 4. Test the filter by clicking on the appropriately named 'Test Search' button. 5. It will probably find all the Tamil mail. 6. Click 'Next Step' button. 7. Select the 'Delete it' checkbox and any others that are appropriate. 8. Click the 'Create Filter' button. You're done. If you want, you can use the OR and AND keywords to make a more complicated and possibly more accurate filter (fortunately the letter க is common enough to make this unnecessary). As for your other question, I'd rather not answer because I don't want to get sucked into that discussion. -- Roshan George ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

You filter it yourself. I decided to try this out and you know what? Filtering email with subjects containing the letter 'க' resulted in every email with a Tamil subject in the last 3 weeks (I don't have mail from this list before this date stored on my computer) being filtered and not one email with a non-Tamil subject being filtered.
