• Windows, Apache and MSSQL Authentication

  - by user1114330

  I have a create database script written in perl. I remember it working just fine another machine. A couple years later using a Vista machine I am trying to use it again and it keeps failing. The main difference is that now I am using Apache instead of IIS. In the script the IUSR account is granted permissions as it needs to write to the database as a part of another program. IIS has been uninstalled on this machine but the IUSR account still exists. The NT AUTHORITY\IUSR is also seen in the logins drop down in MSSQL(2012). The machine is running Vista Home Edition. However when running the script I get errors that say that NT AUTHORITY\IUSR cannot be found. I tried also with COMPUTERNAME\IUSR just for the heck of it and of course it was not found. I also tried with IUSR alone and for some reason the user isn't being "found"? Any ideas?

• Saving Proxy Settings from different networks

  - by elcool

  I go to different clients and they all have their networks with different proxy settings. So I'm always having to change the proxy settings and saving the info in a notebook, and it becomes a pain after a while. So, any good way to save all those proxies and have them recognize the network I'm on and load up? Currently I maintain two: one in IE for clients, and none in Firefox for when I'm at home. And I think the last network I was on asked me to save the proxy and I think it went to system settings. But I don't know much about networking.

• Sharing RAM resources between 2 or more computers

  - by davee44

  I know there was a somewhat similar question before: How to share CPU or RAM? But, let me just specify it a little more... When Microsoft Windows requires more RAM capacity than available it uses a swap-file to temporarily store the data there, this is actually something like a hard-drive-based RAM. This technology is used for many years. Theoretically, it shouldn't be too hard to implement a similar technology that uses the RAM of different computer(s) in the network for temporary data storage. This just requires a software that runs on computers in the network that accepts and returns data from/to the main computer and keep that data in the RAM; plus the operation system of the main computer must have the ability to use computers in the network instead of (or in addition to) the swap-file. I wonder, are there any implementations of this idea? This would allow users to build RAM clusters using all of their home or office computers, that will boost the performance of a single computer for some development/gaming/video tasks, etc.

• htaccess rewrite condition old site to new site with querystring

  - by Brandon Braner

  I am not even going to pretend to fully understand how htaccess rewrite conditions work. I've been working on this for a while searching and searching. I have an old Wordpress site www.old-site.com and a new site www.site.com. Wordpress uses query strings page_id=# to redirect to pages. On the old site page_id=2 went to a specific page but on the new site it goes the the home page. I need old-site/?page_id=2 to go to site.com/our-company Here is what I am trying RewriteCond %{HTTP_HOST} ^(www\.)?old-site.com$ [NC] RewriteCond %{QUERY_STRING} ^page_id=2$ RewriteRule ^(.*)$ http://www.site.com/our-company/ [R=301,L] If I take out the rewrite condition for query string it redirects all traffic from old-site.com to the company page on the new site. Where am I going wrong? I have about 15 redirects I need to do this way.

• How to automatically copy a file uploaded by a user by FTP in Linux (CentOS)?

  - by Buttle Butkus

  Outside contractor says they need read/write/execute permissions on part of the filesystem so they can run a script. I'm ok with that, but I want to know what they're running, in case it turns out there is some nefarious code. I assume they are going to upload the file, run it, and then delete it to prevent me from finding out what they've done. How can I find out exactly what they've done? My question specifically asks for a way of automatically copying the file, which would be one way. But if you have another solution, that's fine. For example, if the file could be automatically copied to /home/root/uploaded_files/ that would be awesome.

• What is causing my wireless problems?

  - by user34629

  I have a Dell XPS M1330, since I moved to my new house, the wireless barely works on it, my housemates report no problems, so I guess it's something to do with my laptop. It's eratic in normal mode, sometimes not working for days, usually working on-and-off, forcing me to reload pages a few times before they work, etc. It works perfectly in safe mode, the driver I'm using is the Intel PRO/Wireless 3945ABG Network Connection, version 12.4.4.5, with a date at 26/10/2009, the most recent one I could find, bluetooth is not enabled, and I'm running Vista 32-bit Home Premium, which it shipped with. I also tried disabling IPv6 and resetting the IP stack, both to no avail. Can anybody help me?

• Windows/Samba connection error

  - by Gomibushi

  I have a Linux fileserver serving up /home for linux and windows users. I was able to connect from my windows client, but not from a DC. Then suddenly I could connect from the DC too. The linux servers run Centrify clients, and as such are part of the domain. All on same subnet. This is what the the log.smbd says, repeatedly: [2010/02/11 11:25:57, 0] lib/util_sock.c:read_data(534) read_data: read failure for 4 bytes to client 192.168.200.3. Error = Connection reset by peer On Windows it appeared as an "unknown error". EDIT: the error code is "0x80004005". We are developing a system depended on the samba share, and are worried this will appear again. It would be nice to pin point the root of this. Any ideas what this might be? Places to look?

• Problems getting auditd set up on my server

  - by Tola Odejayi

  I'm trying to figure out which processes are deleting files from a specific directory, so I want to set up and run auditd on my system. I've set up the following rule in audit.rules: -w S unlink -S truncate -S ftruncate -a exit,always -k cache_deletion -w /home/myfolder/cache Then I type this to start the audit daemon: auditctl -R /etc/audit/audit.rules -e 1 But I get this error message: Error - nested rule files not supported Does anyone know what I am doing wrong here, and how I can resolve this? Also, what do I have to do to get the daemon running at startup?

• Workaround broken sudo?

  - by perreal

  I managed to break sudo by deleting the libc.so.6 sym-link in /lib. I copied the actual file and created a symbolic link with the same name under my home directory by using LD_PRELOAD=/lib/libc-2.11.3.so. At this point, all binaries linking libc are working through preload except sudo. For sudo, I need to write (and don't know why): $ /lib/ld-linux-x86-64.so.2 --library-path . /usr/bin/sudo but this gives me: $ sudo: must be setuid root Checking the permissions: $ ls -l /usr/bin/sudo $ -rwsr-xr-x 2 root root 166120 So the setuid bit is actually set. Question: I need to create a symbolic link named /lib/libc.so.6 through my active ssh connection without using sudo, or, make sudo work somehow. I don't have the root password and I can't connect through ssh anymore. Is there any other way I can get authorization?

• How to join a Windows Domain an Map NEtwork Drives on Ubuntu Partition

  - by AgainstClint

  I just installed the current build for Ubuntu on a partition for my work computer. I am a novice when it comes to Linux/Ubuntu, which is why I installed it along side windows. I want to learn how to operate and use Ubuntu much more than I do now, so I figured installing it and trying to do day to day functions here would be a "Thrown into the pool with sharks" way to do it, and I like that way. I did however have a few questions: We are on a Domain in Windows, is there any way to join that domain using the Ubuntu partition? We Also have 16 mapped network drives. I don't actually need ALL of them mapped for Ubuntu, but is there a way to Map at least one of them to see/use here in Ubuntu. Outlook Corporate email, how can I sign in/use it while...well, you get the idea. As I said earlier, I am VERY new to Ubuntu, i've only played around with it a bit at home and never at the office. If you could simplify it down for me a bit, that would be great.

• Virtualbox: Raw linux partition not booting

  - by abalter

  I have a dual-boot laptop with Windows 7 and Ubuntu 12.04. I am trying to boot the ubuntu partition from windows using Virtualbox. I have successfully created the .vmdk, and created the virtual machine. However, I can't get it to boot (in Virtualbox). All I get is a black screen with the cursor in the top left. I wonder if I'm specifying the partitions correctly. My Ubuntu install has 3 partitions: \, \boot, \home. No swap partition. These are all in Disk 0, partitions 3,4,5 respectively. The command I used to create the .vmdk is: VBoxManage internalcommands createrawvmdk -filename C:\Users\abalter\.virtualbox\ubuntu.vmdk -rawdisk \\.\PhysicalDrive0 -partitions 3,4,5 Then I create a virtual machine based on that .vmdk. Why won't it boot?

• Mac and different Spaces: conserving the windows arragement when changing the external monitor

  - by user10826

  Hi, I use Mac OS X Leopard with 4 different Spaces and an external monitor at workplace, which is located above the laptop. On each Space I work on a different project, with different terminal windows and Xcode and Finder windows. The problem happens when I am at home, then I use an external monitor but now located at left position. When the MacBook wakes up, everything gets messed up and even some windows switch from one space to another. Could I somehow fix it so always the windows belonging to one Space remain there and also the association to main/external monitor even if I change to another external monitor? Thanks

• What is meant by "no password set" for root account (and otthers)?

  - by MMA

  Several years back, we were more accustomed to changing to the root account using the su command. First, we switched to the root account, and then executed those root commands. Now we are more accustomed to using the sudo command. But we know that the root account is there. We can readily find the home directory of user root. $ ls -ld /root/ drwx------ 18 root root 4096 Oct 22 17:21 /root/ Now my point is, it is stated that "the root password in Ubuntu is left unset". Please see the answers to this question. Most of the answers have something to this effect in the first paragraph. One or two answers further state that "the account is left disabled". Now my (primary) questions are, What is meant by an unset password? Is it blank? Is it null? Or something else more cryptic? How does the account becomes enabled once I set password for it? (sudo password root) In order get a better understanding, I checked the /etc/shadow file. Since I have already set a password for the root account, I can no longer see what is there (encrypted password). So, I created another account and left it disabled. The corresponding entry in the /etc/shadow file is, testpassword:!:16020:0:99999:7::: Now perhaps my above queries need to be changed to, what does an ! in password field mean? Other encrypted passwords are those very long cryptic strings. How come this encrypted form is only one character long? And does an account become disabled if I put an ! in the (encrypted) password field?

• Cannot SSH into Virtual Machine

  - by MasterGberry

  I am running a CentOS VM on my desktop that I use for development testing when coding in python. At my school I have a dedicated IP setup for the VM and my desktop so I never seem to have an issue ssh'ing from desktop into VM. I am now at home for winter break and cannot seem to SSH into the VM using the local ip address behind my router, the external IP with port 22 forwarded to my VM, or anything. Strangely enough I can ssh into my production server and then fromt here ssh into the VM, but not from my desktop to the VM directly What should I do to get this to work? Thanks

• Kernel compiling with -j2+ parameter ends prematurely with no error message or output bzImage

  - by Minix

  I've noticed quite a while ago that compiling a kernel with the parameter -j set to 1 or more doesn't produce a bzImage. Instead, it ends prematurely without any advice. I have reproduced the same behavior in both my netbook and home server. As far as I'm aware, the point where the compilation stops is random - Compiling twice with the same parameters will probably stop at different files. However, when I run make with no -j* parameter the compilation ends just fine and outputs a working bzImage. Both machines run Intel Atom (N270 on the netbook and 330 on the server) and I've compiled for these processors. If I recall correctly, I've tried compiling both with Atom and with generic x86_64 options. The kernel version I'm building is 2.6.34.1 I've always compiled normally with those options in my Core2Duo and Pentium Dual Core machines. Has anyone experienced this issue? Any ideas why does this happens? Is there a fix or workaround?

• Problems with connecting to wireless network on windows 7

  - by Naveen

  I have a Dell laptop with Windows 7 (Home premium) 64 bit edition installed on it. I use a Wi-Fi router to browse the net. My problem is, I lose the network connection every 10 minutes or so. The network icon on the system tray shows the refresh icon and the status as "identifying network". The network is fine and works fine with my phone. I saw on the net this may be caused if I have enabled IPv6, so I disabled it but still problem persists. When I look at the event log I see the following entries: "Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0xXXXXXXXX. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server." I have also installed VirtualBox(32 bit edition) on the laptop. Does anybody any solution to this?

• Debian/Linux backup files changed by user

  - by verhogen

  I would like to backup my server that is hosting a few websites in such a way that I can restore everything to the way it was from a fresh format. I know that I should backup all the home folders and then probably my /etc/ folders. Is there a way to figure out all the folders that are relevant for backup in that they were not automatically generated or installed from apt-get? It would ideally restore all the users with their current passwords as well. Basically, enough to clone the system but only copying configuration files.

• Most efficient RAID configuration with 6 disks?

  - by Bob King

  I have a hand-me-down server that I'm setting up at home and it's got 6 72Gb hard disks (as well as 2 18Gb drives that I'm using for the OS). What is the best way to configure those 6 drives? Should I RAID 5 or 6, or go with something simpler, like mirroring? I'm planning to use it to hold a source control repository, and possibly data for a development SQL server. The machine has a hardware raid controller. It is an old IBM server.

• Can't get port forwarding to work on Ubuntu

  - by Znarkus

  I'm using my home server as NAT/router, which works well. But now I'm trying to forward port 3478, which I can't get to work. eth0 = public interface eth1 = private network $ cat /proc/sys/net/ipv4/conf/eth0/forwarding 1 $ cat /proc/sys/net/ipv4/conf/eth1/forwarding 1 Then to forward port 3478 to 10.0.0.7, I read somewhere that I should run iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 3478 -j DNAT --to-destination 10.0.0.7:3478 iptables -A FORWARD -p tcp -d 10.0.0.7 --dport 3478 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT I also ran ufw allow 3478 But testing port 3478 with http://www.canyouseeme.org/ doesn't work. Any idea what I have done wrong?

• xen 4.0 squeeze fails to start guests with: launch_vm: SETVCPUCONTEXT failed

  - by mcr

  As Chris Benninger says over at: http://www.benninger.ca/?p=58 lots and lots of people have the problem with Squeeze and xen4.0 telling them: launch_vm: SETVCPUCONTEXT failed (rc=-1) but nobody seems to know what the solution is. I don't know either, but at least here, a solution might get recorded. In my case, I can start one guest machine. An identical configuration for a second machine fails. Whichever one I start first, is the one that runs, the other gets the error. I've got at least a dozen other systems (at my work) running great with Squeeze and 64-bit XEN, but not this new machine at home.

• What happened to NewsGator and FeedDemon?

  - by user1413

  It's been a while since I used NewsGator and FeedDemon. I tried to log on last week and today and both seem broken. NewsGator no longer has a login -- it has been replaced by DataWire on the www.newsgator.com home page and my login no longer works. FeedDemon is completely broken -- it is no longer sucking in RSS feeds. What happened? And what do I do now? Do I need to get a completely new RSS feeder? Or is there something else that NewsGator is doing that I'm not aware of?

• How to get Apache to follow symlink instead of downloading it?

  - by user792445

  I am just using the standard apache config file which mentions that it follows symlinks, but when I hit the url http://localhost/test it downloads the symlink file instead of following it. What config do I need to change to get apache to follow the symlink instead of downloading it? This is an ls on the directory: $ ls -al total 10 drwx------+ 1 SYSTEM SYSTEM 0 Oct 20 10:55 . drwx------+ 1 SYSTEM SYSTEM 0 Aug 26 12:27 .. -rw-r--r--+ 1 me None 47 Oct 20 10:14 index.html lrwxrwxrwx 1 me None 29 Oct 19 17:10 test -> /home/me/projects/test This is in my apache config file: <Directory "D:/Program Files (x86)/Apache Software Foundation/Apache2.2/htdocs"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory>

• How to setup Microsoft Remote Desktop?

  - by jsoldi

  I'm trying to establish a connection between this app and my Win 8.1 Pro PC, but every guide I've found so far skip steps such as what to put under PC name or under Gateway. Also, should the User name be my email or something else? I've also no idea how to find or add a user in the step 6 of this guide because the only location listed is my PC and I don't even know what am I supposed to search for. I'm not even sure whether I have to add a user or this is an step I can skip. A comprehensive guide for people without experience in networking would be highly appreciated. Both my android tablet and PC are connected to the internet through a home router, in case this matters.

• Booting an EXT4 image file from GRUB2

  - by sjjg

  My friend needed a fast HDD so I gave her my small 64GB SDD. This SSD had my Linux install on it. I used dd to make an image of the partition (boot, root and home on one partition). This partition is now sitting on a traditional 500GB EXT4 formatted drive. Is there any way I can get GRUB to just boot using this .img file I have? I'm not getting my SSD back and I can't be bothered to go through the hassle of setting up my Linux install from scratch. I have come across loopback support in GRUB for ISO images. Does this support EXT4 also? I don't seem to be able to find anything specific and don't want to trash anything. Cheers.

• Trying to figure Windows 2008 Server and Active Directory - complete novice!

  - by Simon E

  I am a novice in networking and I want to learn more about Windows Server 2008 and Active Directory. Basically I have serveral Windows 7 PC's in my home and an IBM server with Win Server 2008 installed. I have enabled Active Directory and set the server to have a static IP. Thats as far as I have got and I feel a little overwhelmed at the moment as I am not sure what to do next. What I eventually want to do is have the Windows 7 PC's to be able to be authenticated by the server - basically a mock up of what most large or medium sized businesses/organisations run. Sorry if I sound a bit sketchy, but I understand some things but not the whole picture, I guess I just need confirmation that I am sort of on the right track :) Also what are some good resources out there you can point me to, what are the absolute basics I need to to get started so I can further my learning?
