• Drive By Download Issue

  - by mprototype

  I'm getting a drive by download issue reported on www.cottonsandwichquiltshop.com/catalog/index.php?manufacturers_id=19&sort=2a&filterid=61 reported from safeweb.norton.com when I scan the root url. I have dug through the entire site architecture, and code base and removed a few files that were malicious, i upgraded the site's framework and fixed the security holes (mostly sql injection concerns)..... However this one threat still exists and I can't locate it for the life of me, or find any valid research or information on removing this type of threat at the server level, mostly just a bunch of anti-virus software wanting to sell you on their ability to manage it on the client end. PLEASE HELP Thanks.

• Restricting A Directory Through .htaccess

  - by Whitechapel

  I'm trying to put all of my FTP accounts into a folder on /public_html/ftp and password protect it so search bots can't crawl their private files. I'm also trying to redirect all site traffic from the non-www to www. I keep getting 500 errors when accessing the site, and I need to point it to www.vivalanation.com/ftp to www.vivalanation.com/ftp/, because the /ftp just errors out, you need the trailing slash. Here is my .htaccess in the /public_html/ftp folder: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] AuthName "FTP Access" AuthType Basic AuthUserFile /home1/vivalst/.htpasswds/public_html/ftp/passwd Require valid-user I created a passwd file in /.htpasswds/public_html/ftp And here is my basic .htaccess in the root of /public_html/: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

• What's the difference between "Service" and "/etc/init.d/"?

  - by Marco Ceppi

  I've been managing server installations both on and off Ubuntu flavor for some time - I've become quite adjusted to /etc/init.d/ for restarting servcies. Now I get this message: root@tatooine:~# /etc/init.d/mysql status Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service mysql status Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the status(8) utility, e.g. status mysql mysql start/running, process 14048 This seems to have been brought about in the latest LTS of Ubuntu - why? What's so bad about /etc/init.d/ and what/is there a difference between service and /etc/init.d/?

• Ubuntu dual-boot errors in 13.10

  - by Charlie

  Specs: Lenovo U530, 500 GB HDD, 8 GB RAM, 64-bit, i7 Intel Processor with integrated graphics I'm trying to dual-boot Ubuntu but I have the following problems: After booting from live DVD, the GRUB loads but with the following errors: "Could not open '\EFI\BOOT\fallback.efi': 14" and "error: variable 'root' isn't set. I have disabled Fast Startup and SecureBoot before booting the disc. Also, after trying to "Try Ubuntu without installing" my screen, and DVD Drive shutoff momentarily but then my drive boots up but my screen remains black and sometimes flashes but doesn't display anything. I will greatly appreciate any help. P.S. I don't have any previous version of Ubuntu installed so this is NOT an upgrade from a previous version.

• How can I use a CanoScan N640Pex scanner over a USB/parallel cable?

  - by detly

  I have an old CanoScan N640Pex flat bed scanner and a USB-to-parallel port cable through which I can connect it to my PC. Unfortunately neither Simple Scan nor XSane detect the scanner. I'm running Ubuntu 12.04 (plus updates and backports) with kernel 3.2.0-31-generic. dmesg tells me this when I plus the cable in: [256411.641910] usb 7-1: new full-speed USB device number 10 using uhci_hcd [256411.872392] usblp0: USB Bidirectional printer dev 10 if 0 alt 1 proto 2 vid 0x067B pid 0x2305 [256411.872417] usbcore: registered new interface driver usblp lsusb shows this device for my cable: Bus 007 Device 010: ID 067b:2305 Prolific Technology, Inc. PL2305 Parallel Port The device node created is /dev/usb/lp0 crw-rw---- 1 root lp 180, 0 Sep 9 17:46 /dev/usb/lp0 There is no extra information from any of these commands when I attach the scanner to the cable and power it on, though. I suspect I might need to change something in /etc/sane.d/canon_pp.conf, but I have no idea what to put for the ieee1284 line, since there is pretty much zero documentation for that parameter. So how can I get it to work?

• How to hide process arguments from other users?

  - by poolie

  A while ago, I used to use the grsecurity kernel patches, which had an option to hide process arguments from other non-root users. Basically this just made /proc/*/cmdline be mode 0600, and ps handles that properly by showing that the process exists but not its arguments. This is kind of nice if someone on a multiuser machine is running say vi christmas-presents.txt, to use the canonical example. Is there any supported way to do this in Ubuntu, other than by installing a new kernel? (I'm familiar with the technique that lets individual programs alter their argv, but most programs don't do that and anyhow it is racy. This stackoverflow user seems to be asking the same question, but actually just seems very confused.)

• Best practice, or generally best way to set up web-hosting server, permissions, etc. [closed]

  - by Jagot

  Hi, I'm about to set up a server upon which a friend and I will be hosting web sites, and I'll be using Debian. I've set up a LAMP solution many times just to using for local testing purposes, but never for actual production use. I was wondering what are the best practices are in terms of setting the server up, in reference specifically to accessing the web root directory. A couple of the options I have seen: Set up a single user account on the server for us both to use and use a virtual host to point to the somewhere in the home directory, e.g. /home/webdev/www. Set each of us up a user account, and grant permissions in some way to /var/www (What would be the best way? Set up a new group?) I want to get this right when I first set this up as there won't be any going back for a while once our first site is up and running. Appreciate any guidance in advance.

• After 10.10 -> 11.04 upgrade, can only login via Classic (No Effects)

  - by Ryan P.

  Yesterday I upgraded from 10.10 to 11.04, everything seemed to go okay until immediately after login: the desktop goes into a "corrupted" looking state (similar to having too high resolution set). I can see some kind of movement by moving the mouse around/right clicking, and can enter text terminals via ctrl + alt + f1 It does this in both plain "Ubuntu" and "Ubuntu Classic", and only seems to login/startup properly with Ubuntu Classic (No Effects). I have checked my video card (Radeon X600) and run the unity support test which passes with all "yes" results (Unity supported: yes): /usr/lib/nux/unity_support_test -p I have tried re-installing my Ubuntu desktop: rm -rf .gnome .gnome2 .gconf .gconfd .metacity sudo apt-get remove ubuntu-desktop sudo apt-get install ubuntu-desktop With no success. I can workaround for now with Classic (No Effects), but I'd really like to find the root problem. Any suggestions on what else to try would be appreciated!

• Fixing a broken toolbox (In Visual Studio 2010 SP1)

  - by mbcrump

  I was recently running into a situation where every time I opened Visual Studio 2010 SP1, the following message would appear for about 60 seconds or so: "Loading toolbox content from package Microsoft.VisualStudio.IDE.Toolbox.ControlInstaller.ToolboxInstallerPackage '{2C98B35-07DA-45F1-96A3-BE55D91C8D7A}'" After finally get fed up with the issue, I started researching it and decided that I’d share the steps that I took to resolve it below: I first made a complete backup of my registry. I then removed the following key: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Packages\{2c298b35-07da-45f1-96a3-be55d91c8d7a}] I went to the following directory: C:\Users\Your Name Here\AppData\Local\Microsoft\VisualStudio\10.0\ and created a folder called bk and moved the .tbd files to that folder (they are hidden so you will have to show all files). I then removed the .tbd files in the root directory. I then launched Visual Studio 2010 SP1 again and it recreated those files and the problem was gone. Anyways, I hope this helps someone with a similar problem. I created this blog partially for myself but it is always nice to help my fellow developer.  Thanks for reading. Subscribe to my feed

• Have search engines recognise multi-lingual sites

  - by mark

  Hello. I have organised my site by language using the following structure: www.domain.com #spanish language version www.domain.com/en #english language version The site is of Spanish subject matter hence Spanish language takes priority at root of domain. Although the site is new at this stage I would hope visiting from google.com and google.es would return English and Spanish versions respectively. Are there any particular steps I need take to separate the two. Should I add them both as individual sites in Google's webmaster tools and also should I submit individual site maps for each 'site' or as a whole? Thanks in advance.

• Why can't my jsp page read chinese chars from mysql? [migrated]

  - by Canking

  The mysql chars is utf-8, and the jsp page is also set to utf-8. I use the method: DriverManager.getConnection("jdbc:mysql://localhost:3306/jsptest?"+"useUnicode=true&characterEncoding=UTF-8","root",""); But it can not be use. When I insert Chinese chars into mysql and select it out, that would be proper functioning. The question is when I select some Chinese chars that I write into mysql at first, it would be all the "?" at the Chinese char place! Please watch the picture:

• Move site to new domain divided by language across subdomains

  - by mark

  I managed to find a nice domain for a fairly fledgling site of mine that actually hasn't been parked by scumbag squatters. Given the upcoming move I'm thinking I'd take the opportunity to split the content across subdomains according to language, much like wikipedia for example: current: www.old-domain.com/en/subject # English www.old-domain.com/subjecto # Spanish (default so not locale in url) proposed en.new-domain.com/subject es.new-domain.com/subjecto The advantage of doing this is a fairly competitive keyword such that I may wish to put a copy of my application on a Spanish slice in order to gain a few serp's. Also pure vanity. Google's webmaster tools allows me to move to the new domain and I can add the root domain and the subdomains but forward to only one. I'll 301 from the old domain appropriately but is there anything I should know about webmaster tools in this respect where effectively I'm moving to two addresses? (Feel free to dissuade me from doing this if it's a bad idea in comments.) I've now asked this same question on google's forums.

• eth0 not working on startup

  - by user4106

  Hi to all, This might sound strange but, working with my Lubuntu 10.04 i've experienced troubles when connecting to my eth0 newtwork. After some googling, i've found out that by writting in the CLI the following command: mii-tool eth0 -F 10baseT-FD and activating the eth0 in the toolbar (by clicking "activate eth0") everything works just fine. Well, up to now, i did not have any problem, because every time i turned on the computer i had to do this, but it was very little effort.But now, i would like to use the machine as a file server, accesing it by ssh, without monitor or keyboard. So, i won't be able to make this actions, and can't do this at startup because mii-tool needs root permissions. So, the question is: Do you know what does that command do, and how can id make that change permanent? Or do you know any other solution for my problem? I hope i was clear! If not, tell me and i'll try to be as clearer as possible. Thanks in advance!

• Ubuntu VM cannot start after Kernel upgrade

  - by AAz

  Several Ubuntu 10.04 VMs were restarted after few months and began getting "Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)" message. Restoring those VMs from backup (to the "paused" state) allows to boot normally. However restarting the VM again results in the mentioned error message. I suspect it's the updated kernel version (2.6.32-37-server, 2.6.32-38-server) that misbehave - another Ubuntu VM (that's used as template for those failing VMs) still has 2.6.32-24-server and reboots fine. We're using HyperV (2008R2) as the server host. Nothing were changed in it's configuration. Has anyone faced this issue, please advise the solution. Many Thanks in advance!

• Change permission of raw device by UUID

  - by Omid Kosari

  I am using "Apache Traffic Server" which may and it is better to use raw device like /dev/sdb without mounting it as a directory . So i should change the permission of /dev/sdb from root to user "trafficserver" to allow it formatting whole device as it likes . The problem starts after each reboot because /dev/sdb changes randomize so i should use UUID . But i can not change the permission of /dev/disk/by-uuid/48c2fac6-06eb-42c7-8b8a-3b83b781f28c . Is there a way to permanently change permission of disk drive by UUID ?

• Is there an apt command to download a deb file from the repositories to the current directory?

  - by Lekensteyn

  I am often interested in the installation triggers (postinst, postrm) or certain parts of packages (like /usr/share and /etc). Currently, I am running the next command to retrieve the source code: apt-get source [package-name] The downside is, this file is often much bigger than the binary package and does not reflect the installation tree. Right now, I am downloading the packages through http://packages.ubuntu.com/: Search for [package-name] Select the package Click on amd64/i386 for download Download the actual file This takes too long for me and as someone who really likes the shell, I would like to do something like the next (imaginary) command: apt-get get-deb-file [package-name] I could not find something like this in the apt-get manual page. The most close I found was the --download-only switch, but this puts the package in /var/cache/apt/archives (which requires root permissions) and not in the current directory.

• Can't find my DVD drive in Ubuntu 12.04

  - by user72953

  I am completely new to Linux, due to some problems in my Windows I decided to give Linux a try. I am quite liking it accept for some minor issues. The biggest of them is that I cannot find my DVD drive in Ubuntu. After I insert the disk, the drive's green light flickers and then nothing. I don't get anything on my unity bar or desktop. There is no folder inside my /dev folder which indicates a dvd drive. There is a cdrom folder in my root folder but nothing is there. If you guys know what's wrong, I'd appreciate the help. Am a complete newbie so don't expect me to know anything about Ubuntu, although I have spent lots of hours in last 2 days googling my issue so I have basic information...

• How do I know if I've gone too far with processing things in a game?

  - by ThePlan

  A common programming quote I see every day is: Premature optimization is the root of all evil! I admit I'm one of those guys that like to do premature optimization in a pretty obssessive manner but that's probably because I'm not aware how powerful modern processors are. I can think of lots of sollutions for a problem, but all of them are tough on the memory side, and I keep thinking "This will hurt me more in the future when I'll have to re-do it because it's bad performance-wise." How do you know when the code you are thinking of is going too far and is not a case of premature optimization? How much can your game handle at a time before performance becomes a problem?

• Given a used laptop with Ubuntu installed, how do I get past the password demands?

  - by user287494

  Recently given a laptop with Ubuntu 12.1 installed alongside Windows 7. Can only access Ubuntu, which is fine for everyday use (LibreOffice, Firefox, etc.) but there's an authentication password required to install the 500+ updates, and when trying to run anything in terminal, it asks for "quiz's" password. It won't allow me to go into root mode to bypass the password (if that's even a real thing?). I'm completely new to Linux, but am fascinated at the capabilities and would like to mess around some more, but keep getting stopped by these passwords. What do I have to do? Uninstall and re-install? How does one do that if I don't even have access to the Windows 7 OS because it is password protected as well? Thanks in advance for any information and help.

• A peculiar issue with nm-applet

  - by montreux

  There is a somewhat strange error that I've noticed with my gnome sessions. It's not a problem that causes a lot of trouble, but at times it becomes annoying. Anyway, here it is: when I fire up gnome-session-fallback (which is the main one I use), the network applet doesn't run with root permission. Here is what it looks like http://i.imgur.com/8kc7Vrd.jpg . On the other hand, here is what the regular gnome session looks like http://i.imgur.com/wfkkE3E.jpg . From the regular session I can easy edit and add networks, but from fallback session I cannot add/edit anything, or turn off/on the wireless or networking. Any ideas?

• How do I make a USB RS232 dongle show up in /dev/ttyUSB* ?

  - by mtrw

  I have a couple of FTDI based USB to Rs232 serial dongles. Sometimes when I plug them into my Ubuntu 10.04 laptop, they show up as /dev/ttyUSB0 and /dev/ttyUSB1, which is what I want to have happen. But sometimes they don't. When they don't, sometimes rebooting fixes the problem and sometimes it doesn't. They always show up in lsusb hanging off of Bus 5: Bus 005 Device 003: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 005 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub I can see them if I do ls /dev/bus/usb/005 as 002 and 003. But if I pass /dev/bus/usb/005/002 to pyserial, which is what I'm using to access /dev/ttyUSBx, I get SerialException("Could not open port: [Errno 13] Permission denied: '/dev/bus/usb/005/002'",).

• How can I install the Realtek RTL8111E version 8168 driver?

  - by Unknown_Fool

  I downloaded and extracted the latest Linux driver version from Realtek. I read the readme file and it instructed me to run ./autorun.sh as root. I did that. It compiled the driver for my kernel, removed the old default module, but then it fails to install the new 8168 module. It claims that it can't be found. Can this driver be installed manually? Is there a way to fix autorun.sh so it can install properly?

• Installing VMware Worstation/Player 8.0.4 on Ubuntu 12.10 fails to load with Unable to start services

  - by user106986

  I have been attempting to install this application for a few weeks without any success. I have installed and uninstalled the application and pathes with no change. I have even tried to load a VM in Virtualbox and install the application there to a base install of Ubuntu 12.10 and it still did not install. I have downloaded the patch and modified it to reflect the version of VMware Worstation and Player I am installing. I still receive the same error I saw in the first attempt to install the software. Which leads me to think that I am missing something. The error is: Unable to start services. See log file /tmp/vmware-root/modconfig-7674.log for details. I have the output of the log file if that will help. According to the dialogue box Virtual Network Device and VMware Blocking Filesystem fail to either load or execute. Any help would be greatly appreciated.
