• Cannot access https sites through any browser on Win XP?

  - by manwood

  This isnt a firewall issue, I can telnet to gmail with no problems, but all browsers (chrome, IE, firefox) return a This web page is not available. error when tring to access it through the browser. I can access the same pages, using the same browsers, on the same machine, but through a different user account with no problem. What the hell is going on? Help appreciated. Edit: This is definitely a windows setup issue - I have just created a new admin account and can access https with problems. This is seriously infuriating.

• Resizing mysterious partition written by DDing an ISO file

  - by Jon

  I downloaded clonezilla and then wrote it to a USB flash drive with this: dd if=clonezilla.iso of=/dev/sdb I've confirmed that the system boots and clonezilla runs from the flash drive. I want to store a clonezilla backup on the same flash drive clonezilla is running on, but I tried it and ran out of space, so I started looking at how to resize the mysterious partition type that was generated from the ISO. fdisk -l /dev/sdb .... Device Boot Start End Blocks Id System /dev/sdb1 * 1 111 113664 17 Hidden HPFS/NTFS .... I've tried using ntfsresize from the Debian ntfsprogs package. I'm trying gparted next, but thought I'd ask here if anyone knows a neat way to resize a partition created on flash from a liveCD image. Thanks in advance Jon ps. Assume Debian 6 please.

• Replacing quotes in a file

  - by Matthijs

  I have a large number of large semicolon-separated data files. All string fields are surrounded by double quotes. In some of the files, there are extra quotes in the string fields, which messes up the subsequent importing of the data for analysis (I'm importing to Stata). This code allows me to see the problematic quotes using gnu-awk: echo '"This";"is";1;"line" of" data";""with";"extra quotes""' | awk 'BEGIN { FPAT = "([^;]+)|(\"[^\"]+\")"}; {for ( i=1 ; i<=NF ; i++ ) if ($i ~ /^"(.*".*)+"$/) {print NR, $i}}' 1 "line" of" data" 1 ""with" 1 "extra quotes"" but I do not know how to replace them. I was thinking of doing the replace manually, but it turns out that there are several hundred matches in some of the files. I know about awk's -sub-, -gsub-, and -match- functions, but I am not sure how to design a search and replace for this specific problem. In the example above, the respective fields should be "This", "is", 1, "line of data", "with", "extra quotes", that is: all semicolons are separators, and all quotes except for the outermost quotes should be removed. Should I may be use -sed-, or is -awk- the right tool? Hope you can help me out! Thanks, Matthijs

• How to get LAN ip to a variable in a Windows batch file

  - by Ville Koskinen

  I'm streaming audio from my Windows 7 laptop to a sound card attached to a router. I have a little batch script to start streaming. REM Kill any instances of vlc taskkill /im vlc.exe "c:\Program Files\VideoLAN\VLC\vlc.exe" <parameters to start http streaming> REM Wait for vlc TIMEOUT /T 10 REM start playback on router plink -ssh [email protected] -pw password killall -9 madplay plink -ssh [email protected] -pw password wget -q -O - http://192.1.159:8080/audio | madplay -Q --no-tty-control - & As you see the http stream is hard coded. It would be nice to get the address dynamically to reuse the script on other machines. Any ideas?

• Is there a command-line utility app which can locate a specific block of lines in a text file?

  - by fred.bear

  The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :)

• Ubuntu 13.10. Can't access Internet and unable to install anything

  - by Crandacular

  After upgrading to Ubuntu 13.10 I was not able to access the Internet on any program that required it. So I uninstalled Firefox but I could reinstall from the software center so I used the terminal, everything ran smoothly, I told me how much additional space would be used, then it said "Err http://us.archive.ubuntu.com /ubuntu/ saucy/main Firefox i386 24.0+build1-0ubuntu1 Could not resolve 'us.archive.ubuntu.com Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/f/firefox/firefox_24.0+build1-0ubuntu1_i386.deb Could not resolve 'us.archive.ubuntu.com' E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?" And with both given possible fixes I also get errors. Please help, it's been like this sense the day the 13.10 update was released

  - by PPS

  I would like to know that, We have a small Wireless Network that covers 40 mtrs indoor. Now we plan to expand our Network Coverage area apporx. 200 Mtrs (Outdoor). Due to our requirement we used TP- Link Access Point TL-WA5210G Outdoor(This AP covers 15Km area). We have 3 blocks between 200 mtrs, We like to connect all the laptops Lan Card directly with required Access-point. What should we do to achieve this, right now we are not getting the full strength signal, when we cross the 80 mtrs. So please suggest me proper configuration for implementing this TP-Link access point. Thanks PPS

• pfsense log file retention

  - by Colin Pickard

  We have a pfSense firewall in our datacentre. By default, pfSense is only storing 500K of firewall filter logs, which is only a few hours for us. How can I increase this? pfSense uses clog rather than the usual BSD newsyslog. I only want the log for debugging firewall rules, not compliance or anything, and the firewall has 100GB of spare disk space, so I'd rather have the logs on the firewall itself than set up a syslog server.

• Two threads in a rails initializer file seems to not run them properly

  - by Luccas

  Initially I was using one thread to listen a queue from amazon and works perfectly. aws.rb Thread.new do queue1 = AWS::SQS::Queue.new(SQSADDR['my_queue']) queue1.poll do |msg| ... but now I appended another thread to listen another queue: ... Thread.new do queue2 = AWS::SQS::Queue.new(SQSADDR['my_another_queue']) queue2.poll do |msg| ... and now it seems to not work. Only the last one receives response... I have to join the threads? I can't understand What is going on?

• Which file format to use for simple video editoring

  - by Craig HB

  I've just bought a Sanyo VPC-CG10 camcorder which saves clips as MPEG-4 (specifically, High-Definition 720p MPEG-4 AVC/H.246) I want a simple, cheap way to edit the clips and as, I'm using Windows Vista, I though Windows Movie Maker would be a good choice. But you can't import mp4 files into Windows Movie Maker. I've tried various codecs, but I'm not sure what is the best format to convert to, so that I can edit the files in Windows Movie Maker. AVI, MPG, WMI... I'm not sure what format is best. Should I try to keep the movie clips in MPEG-4 and edit them in that format (and then which editor do I use?) or is there a better format that I should convert to before editing (and what format is that?) ?

• Can't delete keyboard shortcut set for a .ink file

  - by Sirhaian

  So, I installed the Chrome App Launcher on my PC (now on Win8.1) a few weeks ago, and, as I use it very often, I wanted to assign a keyboard shortcut for it. So, I right-clicked the icon on my desktop, and I assigned Ctrl+Alt+<. The problem is... I moved the shortcut to my taskbar, and suddenly noticed that when I wanted to write the "\" (on a Belgian keyboard), it launched the Chrome App Launcher, which is very annoying. I wanted to change it back, but I can't... I deleted the taskbar shortcut, but the keyboard shortcut still launches the App Launcher. I also tried creating a new shortcut with the same association, hoping that it would crush the existing one, but it didn't work. I searched on Google for similar issues, and I couldn't find any... x~x So... How can I delete this shortcut association..?

• Screenflow file type convert to AVI?

  - by Dave

  I've got a couple of large files 2 - 3GB each which were of a training course where the instructor used Screenflow on the Mac to record all his keypresses. I'm currently on a PC.. Problem: how to convert from .screenflow (and associated .scc files) to AVI or something a PC can play? Problem2: If I borrow a Mac can I d/load http://www.telestream.net/screen-flow/overview.htm (which I think was the package) and convert the files?

• How can I gain access to a player instance in a Minecraft mod?

  - by Andrew Graber

  I'm creating Minecraft mod with a pickaxe that takes away experience when you break a block. The method for taking away experience from a player is addExperience on EntityPlayer, so I need to get an instance of EntityPlayer for the player using my pickaxe when the pickaxe breaks a block, so that I can remove the appropriate amount of experience. My pickaxe class currently looks like this: public class ExperiencePickaxe extends ItemPickaxe { public ExperiencePickaxe(int ItemID, EnumToolMaterial material){ super(ItemID, material); } public boolean onBlockDestroyed(ItemStack par1ItemStack, World par2World, int par3, int par4, int par5, int par6, EntityLiving par7EntityLiving) { if ((double)Block.blocksList[par3].getBlockHardness(par2World, par4, par5, par6) != 0.0D) { EntityPlayer e = new EntityPlayer(); // create an instance e.addExperience(-1); } return true; } } Obviously, I cannot actually create a new EntityPlayer since it is an abstract class. How can I get access to the player using my pickaxe?

• Windows Virtual PC File Copy from host very slow

  - by Shiv Kumar

  I have a Windows 7 desktop on which I've installed Windows Virtual PC and an instance Windows 7. I also have virtual XP instance on the same host. The problem I am having is that copying files from the host to the virtual machine is dog slow. I'm talking 17KB/sec. The host machine has a gigbit NIC. While using the XP virtual instance to do the same I didn't notice a huge difference but on the Window 7 virtual instance the time is really slowing me down. Is there something I need to do (settings) to fix this? I've attached an image of the Resource monitor (of the virtual Windows 7 instance) that shows my network traffic going in bursts rather than relatively steady. The files are on a "public" folder on my host machine.

• Is it time to add IPv6 access to my websites?

  - by Rob Hoare

  I have several dedicated servers and VPS servers, and some of those are at companies that have provided me with native IPv6 blocks (in addition to the IPv4 IP addresses). Does it currently make sense to point an AAAA record to an IPv6 address on my server, in addition to the A record pointing to the IPv4 address? This would be for (for example) the www subdomain. (the networking and web server software would be set up on the server to respond appropriately). A while ago I read that a small percentage of users (1 in a thousand?) would have slow or no access if a subdomain had both A and AAAA records because their networking software asked for one and got the other. Is that still the case, will adding an AAAA record inconvenience some users, or is the percentage already smaller and falling? In other words, is now the time to get around to adding native IPv6 support for a busy website aimed at the general public, or is it still too early?

• Encrypt tar file asymmetrically

  - by DerMike

  I want to achieve something like tar -c directory | openssl foo > encrypted_tarfile.dat I need the openssl tool to use public key encryption. I found an earlier question about symmetric encryption at the command promt (sic!), which does not suffice. I did take a look in the openssl(1) man page and only found symmetric encryption. Does openssl really not support asymmetric encryption? Basically many users are supposed to create their encrypted tar files and store them in a central location, but only few are allowed to read them.

• How can I store all my level data in a single file instead of spread out over many files?

  - by Jon

  I am currently generating my level data, and saving to disk to ensure that any modifications done to the level are saved. I am storing "chunks" of 2048x2048 pixels into a file. Whenever the player moves over a section that doesn't have a file associated with the position, a new file is created. This works great, and is very fast. My issue, is that as you are playing the file count gets larger and larger. I'm wondering what are techniques that can be used to alleviate the file count, without taking a performance hit. I am interested in how you would store/seek/update this data in a single file instead of multiple files efficiently.

• File replication among EC2 instances

  - by Peuge

  I am pretty new to AWS so please excuse my ignorance. We are wanting to have a setup whereby we have a SQL DB instance + web server instance. However we would like the Web server to sit behind an ELB thus allowing us to use Autoscaling. My question however is how to we replicate the web app across instances? Say for example we have two web servers running and we need to make a critical update to the web app, ultimately we would only want to upload to one instance and not both. Is it even best practice to store your web app on the instance or are there better ways to store and share the app between instances?

• Using 301 Redirects on new site when access to old site denied?

  - by Cape Cod Gunny

  I have a situation where I'm standing up a new website on a different web host. I've been denied access to the old site by the hosting company and the old site will most likely be turned off very soon. If my new site contains pages that are named slightly different how do I go about setting up 301 redirects on my new site? For example: www.oldsite.com\aboutus\ www.newsite.com\aboutus.html www.newsite.com\productx.html www.oldsite.com\productx\ Edit: Clarification: The old domain name is different from the new domain name. On my newsite do I just duplicate every page that existed on the old site and place redirect code inside those pages? What does the redirect code look like?

• Looking for a file-system overlay using LD_PRELOAD

  - by ki.lya.online.fr

  Hi, I'm looking for a shared library that is to be loaded using LD_PRELOAD that would modify the view of the filesystem to the client program. Ideally, I'd like to choose the filesystem root (or use / as root) and to overlay the filesystem by renaming filenames. For example, I might want to tell my program to look for /usr/lib/* in /usr/lib32/* instead. Do you know of such a program ? Thanks.
