• Volume size doesn't match Disk size after gparted expansion

  - by Cybersylum

  I just expanded a basic disk on a Windows XP VM from 15gb to 40 gb using GPARTED LiveCD (0.5.2-11). I didn't notice anything unusual during the expansion; but after I rebooted back into Windows, the disk capacity doesn't match the disk size as it should (only 1 volume on the disk). The disk shows as 40gb; but the C: volume still shows the original size. I've tried expanding the disk again with GPARTED (no change), and using VMware converter and have it adjust the size of the volume during the process (complains about a lack of space of snapshot error inside the os). The volume has 27% free space so I don't think it is a space issue. Chkdsk doesn't seem to find anything wrong either. The OS seems to run just fine, it doesn't see the additional space however. Any ideas?

• Which iptables rule do you think is a 'must have'

  - by Saif Bechan

  I have some basic iptable rules set up now for my vps. Just block everything except some default ports, 80,21,22,443. I do get brute forced a lot. I have heard that iptables is very powerful but I have not seen many use cases. Can you give me an example of a(some) rule(s) you always use and give a small example why. I can not find a general best practice post here on SF, if there is any I would like the link. If this is a duplicate I am sorry and it can be closed.

• No network adapter drivers after Windows re-install

  - by Arno

  This is a pretty basic question. I got a PC (Packard Bell Easynote TK11-BZ-010BE) that had linux on it, so I thought, just delete the partition and its alright. Well, it wasn't. I went into grub recovery and couldn't do anything, so I re-installed windows again. Now the problem is that everything works expect my network adapter. When I go to device manager, I get that there aren't any driver's for it installed. But without internet, I can't install the so called driver finders. How should I solve this?

• How to generate the right password format for Apache2 authentication in use with DBD and MySQL 5.1?

  - by Walkman

  I want to authenticate users for a folder from a MySQL 5.1 database with AuthType Basic. The passwords are stored in plain text (they are not really passwords, so doesn't matter). The password format for apache however only allows for SHA1, MD5 on Linux systems as described here. How could I generate the right format with an SQL query ? Seems like apache format is a binary format with a lenght of 20, but the mysql SHA1 function return 40 long. My SQL query is something like this: SELECT CONCAT('{SHA}', BASE64_ENCODE(SHA1(access_key))) FROM user_access_keys INNER JOIN users ON user_access_keys.user_id = users.id WHERE name = %s where base64_encode is a stored function (Mysql 5.1 doesn't have TO_BASE64 yet). This query returns a 61 byte BLOB which is not the same format that apache uses. How could I generate the same format ? You can suggest other method for this too. The point is that I want to authenticate users from a MySQL5.1 database using plain text as password.

• Apache 2.4 and PHP 5.4 getting connection reset errors in the browser

  - by zuallauz

  In the weekend I upgraded my development web server to Apache 2.4 and PHP 5.4. In my web application which was previously working great on Apache 2.2 and PHP 5.3 it now starts getting these messages saying the "connection was reset" in Firefox. See screenshot. I am connecting to the linux machine via local LAN. I'm assuming it might be something to do with the new version of Apache or PHP, or the new LAMP stack which I downloaded from BitNami? It would seem to happen every 5-10 requests and throw this error, perhaps more likely to trigger it is if I send a POST request from a page. Is it timing out the script or something? These are just basic dynamic pages I'm loading and they worked perfectly in Apache 2.2 and PHP5.3. Here are my httpd.conf and PHP.ini if that has any clues. Any ideas? Any help much appreciated.

• Ways for managing the installation and configuration of various software applications and settings i

  - by EmpireJones

  What are some ways for managing the installation and configuration of various software applications and settings in group of linux development and server computers? Is a set of basic scripts a good means of attack? I was thinking about just having a ton of scripts, such as: setup_dev_env [install|uninstall|reinstall] setup_nfs [...] setup_nfs_share [...] setup_http [...] setup_memcache_node [...] Is there any better method? It would be nice to be able to "upgrade" an installation script too, for example, to change common development settings.

• Tunneling HTTP traffic from a particular host/port

  - by knoopx

  Hello, I'm trying to figure out how to access from my development machine (Devel) to a third party web service (www.domain.com) which I am not allowed to directly contact using my office IP address. Here's a basic diagram (i'm not allowed to post images...): http://yuml.me/diagram/scruffy/class/%5BDevel%5D-%5BA%5D,%20%5BA%5D-%5BB%5D,%20%5BB%5D-%5Bwww.domain.com%5D The only machine allowed to access that service is B (production server) but I do neither can directly access it from my development machine (Devel). So in order to access the web service I have to ssh into A, and then from A to B to access www.domain.com Is there any way of tunneling traffic from B to A and then back to my development machine so I can directly access www.domain.com without having to ssh into every box? Devel: My development machine. A, B: Linux servers. I own root access on both. B: Production server www.domain.com: Third party HTTP API production server uses.

• Extending C drive not possible

  - by gokul

  This is my computer partition list. You can see my C drive is running very low on disk space. I wanted to extend my disk space, so I used mmc Disk managment to shrink a volume, but I can't extend it to the C drive because the extended volume in dropdown list of C is not clickable. I've tried many packages, but none were able to do it. My C drive is simple, basic, NTFS, healthy (boot, crash dump, primary partition). The MMC Windows: What should I do?

• Authorization error when testing FTP to UNC

  - by user64204

  We have a Windows Server 2008 R2 with Active Directory (hereafter called DC) running as a domain controller on which we have IIS and an FTP site installed. We have a second Server 2008 (hereafter called SHARE) which is joined to that domain and has a disk shared as a network share (\\share\Office). That network share is used as the ftp's physical path on DC. We've tested the FTP from the IIS FTP configuration panel, by clicking on Basic Settings... then Test Settings.... When setting Administrator as a username with the Connect as... option, everything is fine: When no user is provided we can the below error: Q1: Could someone explain in more understandable terms what is written in the Details text area?

• Memeory Leak in Windows Page file when calling a shell command

  - by Arno

  I have an issue on our Windows 2003 x64 Build Server when invoking shell commands from a script. Each call causes a "memory leak" in the page file so it grows quite rapidly until it reaches the maximum and the machine stops working. I can reproduce the problem very nicely by running a perl script like for ($count=1; $count<5000; $count++) { system "echo huhu"; } It is independent of he scripting language as the same happens with lua: for i=1,5000 do os.execute("echo huhu") end I found somebody describing the same issue with php at http://www.issociate.de/board/post/454835/Memory_leak_occurs_when_exec%28%29_function_is_used_on_Windows_platform.html His solution: Firewall/Virus Scanner does not apply, neither are running on the machine. We can also reproduce the issue on other Developer Machines running XP 64, but not on XP 32 Bit. The guilty guy for the allocation is C:\WINDOWS\System32\svchost.exe -k netsvcs which runs all the basic Windows services. Does anybody know the issue and how to resolve it ?

• Using Terminal Services 'query' in batch file

  - by dboarman-FissureStudios

  I have a batch file that checks several of our servers for a user. From the command: query user %userID% /server:ServerName I want to capture the output before it goes to the screen. Is there a way to redirect the output to a variable? The basic gist of what I want to accomplish is this - we iterate through our servers: query user %userID% /server:Server1 query user %userID% /server:Server2 query user %userID% /server:Server3 query user %userID% /server:Server4 Instead of outputting a message that the user could not be found on a specific server, I would like for it to only notify me if it finds the user on a server.

• Amavis / Atermime - Dynamic Email Signatures (Disclaimers)

  - by Frank

  I am running a basic iredmail install with amavis, postfix, dovecot. I want to use the declaimer feature to automatically append a disclaimer (in our case a signature). The reasoning for this is that clients (ipad, outlook, etc) don’t have to be configured with signature settings, and that we have corporate control over the actual signatures that are posted. Instead of: '[email protected]' => 'boss.domain.com.txt' I am trying to get to %mailbox + ‘@’ + %domain => %mailbox + “.” + %domain + ‘.txt’ This way we can simply use a script to generate the .txt / .htm signature files using just mysql / php. THANKS IN ADVANCE

• How to authenticate users in nested groups in Apache LDAP?

  - by mark

  I've working LDAP authentication with the following setup AuthName "whatever" AuthType Basic AuthBasicProvider ldap AuthLDAPUrl "ldap://server/OU=SBSUsers,OU=Users,OU=MyBusiness,DC=company,DC=local?sAMAccountName?sub?(objectClass=*)" Require ldap-group CN=MySpecificGroup,OU=Security Groups,OU=MyBusiness,DC=company,DC=local This works, however I've to put all users I want to authenticate into MySpecificGroup. But on LDAP server I've configured that MySpecificGroup also contains the group MyOtherGroup with another list of users. But those users in MyOtherGroup are not authenticated, I've to manually add them all to MySpecificGroup and basically can't use the nested grouping. I'm using Windows SBS 2003. Is there a way to configure Apache LDAP to do this? Or is there a problem with possible infinite recursion and thus not allowed?

• How do I overclock a dual core processor?

  - by Pankaj Bhardwaj

  This is a serious problem. I want to speed up my compilation process. I have never been especially fond of overclocking, however my current compilation time for my project makes my crazy! I found information about which parameters I should change to overclock and which values are safe. However, I have one basic problem. I don't have the ability to change this option in my BIOS. It is possible that these options have been blocked by the system administrators? Getting a faster processor is not an option. How do I edit the proper values to overclock my CPU. Do I need to flash my bios to another version? My specs: Entium Dual-Core Cpu E5400 @2.7GHz Asrock motherboard 4GB RAM Windows 7 Ultimate 32-bit

• windows server backup 2008 R2 - what is generating all the change data?

  - by bobjandal

  We have a small relatively idle windows server 2008 R2 installation that does basic filesharing and exchange for about 10 not very active users. When running a windows server backup, the incremental data daily is about 20GB. This is not coming from users shared files, nor from changes in their mailbox sizes. The total size of the installation is 249GB, which is mostly old files. Where is all this data coming from, and how can I reduce it ? Using online backup of the vhd file from the backup is taking a while because of this daily change. Is there some way I can at least see what files are changing and contributing to this data ? Options I can think of but am not sure about: 1) pagefile churning - altho the backup does not include the pagefile, perhaps the changed blocks left behind are included ? 2) logs or something ? but the installation size stays the same every day 3) should I zero free space using sdelete before backing up perhaps ?

• How does the data storage work? [closed]

  - by Andres Adhi

  I am really new to the whole concept of Data storage, Domain, Server and everything else related to this. Can someone pleases explain what a Domain is? How are server part of the Domain and How are Database stored in the Server or Domain? How does a new server be able to connect to existing database server to get all the data needed. I tried to find this information in the web but I am not really finding a good resource. It may be because these is really basic information. I will really appreciate if someone can explain these concept in plain terms. Thanks in advance.

• Questions about Domains and DNS

  - by ShoX

  Hi, I am totally new to the DNS and server hosting world and not quite sure what I need. I want to get a domain, forward it to my own server, so that the user sees example.com in the url bar and example.com/foo/bar will work. Depending on what subdomain it is, it should do different things (another base-directory at webserver, ftp, etc). Also my email should be able to be sent to and received by that server. What irritates me, is the fact, that in the A-record I can only list IP-addresses and no ports. So do I have to set up a nameserver on my own server? Or do I accomplish this via vhosts on my webserver? I would appreciate any help or link to a tutorial. I know how DNS works, know some basic apache-stuff, etc... so no need to explain that. Thanks

I get this error when I run the troubleshooting option. I met two more people in the same hotel with win XP laptop and they too dont have any problem. I have gone to possibly all the forums and website but I haven't been able to fix this error :(. I have done all the basic troubleshooting but I have no luck yet. Pls help.

• VPN within a VM to allow for internet access on the host

  - by David Durrant

  I have a network connection (created under Networks and Sharing) that I use to connect to a customer's site. But when I use this to connect to the site, I loose all access to the public internet, and can only access customer specific items. I want to circumvent this issue by creating a VM and then utilizing the VM to connect to the network location and interact within the customer's domain, while leaving my host machine open to the internet. I'm not extremely familiar with networking, but I have a few basic skills. Please let me know if this is possible and what the correct procedures are. I already have a VM created with VirtualBox, and both the host and guest are running Windows 7 x64. I have created duplicate VPNs already, but can only connect successfully on the host machine.

• subversion: enforce TLS

• Memory is free, but still swapping?

  - by japancheese

  Hello, I'm sure this is a pretty basic question, but I'm just trying to get a grasp of what's going on with my Ubuntu (Hardy Herron) server (running a Rails-based site). It seems that I have free memory available, yet the system is reporting that it is still swapping memory (unless I'm reading this incorrectly?). Here is the "free -m" output total used free shared buffers cached Mem: 1024 905 118 0 33 409 -/+ buffers/cache: 462 561 Swap: 2047 95 1952 Could anyone explain to me some possible reasons that it is maintaining 95mb of swap at all times (it is never less)? I'm just looking for some leads on things I could check out that would explain to me exactly how memory is utilized in Linux.

• Tools to monitor guest OS performance in vSphere

  - by Quick Joe Smith

  I am looking for some tool or way to retrieve performance data from guest VMs running under vSphere 4.1. I am currently interested in the 4 basic metrics: CPU(%), Memory(%), Disk availability(%) & Network utilisation(Kb/s). The issue I have is that all of vSphere's performance data is from a ESXi host perspective (active, shared, consumed, overhead, swapped etc.) which is far removed from the data from the VM's own perspective. For instance, I have a Windows server VM idling, using around 410MB (~25% of its allocated 2GB) as reported by Task Manager, and this is the value I'm after. vSphere's metrics seem unable to arrive at this figure by any reliable and repeatable means. Is anyone aware of tools that can obtain this kind of data? The simpler, the better.

• Dell Studio XPS 16 Runs Hot

  - by dtbarne

  Specs: 1920x1080 i7 1.6 GHz quad core 6GB RAM 1GB ATI Radeon HD 6570M/5700 Series 500GB 7200rpm Hard Drive Love this laptop for many reasons, but it constantly runs hot (CPU is low 70s with basic tasks and often 80+ is not uncommon) and I'm finding it too much to deal with. The laptop feels very hot (almost too hot for a lap) and often gets so hot that the OS slows down or freezes altogether. I've tried cleaning it out and even replacing the thermal paste. I often use an external cooler, but it only helps 3-5 degrees and it's a pain to have to use. I've come to the conclusion that it just runs hot. I have two questions: What is to blame? The i7 processor, the gfx card, or is it just that this laptop has poor cooling? Does the Dell XPS 15 run cooler? I'm looking at replacing my current laptop, but I don't want to run into the same problem.

• Is there a constraint-based scheduling/calendar application?

  - by wonsungi

  Is there a constraint-based scheduling/calendar application? This application would be used to coordinate multiple people's schedules. Two basic use cases: Multiple people need to schedule a time to meet together. Everyone is busy at different days/times. Each person enters blocks of days/times they cannot meet, and the application suggests the best times to meet given a desired time range. Multiple people need to use some common resources for a specific length of time (over some time span like a week), but the exact date/time does not matter. These people enter the resources and time needed, and the application suggests the best way to share these resources. This use case still accounts for people's blocks of busy time. I imagine this program would be graphical, but other interfaces would be acceptable. Also preferable if web-based/works on both PC's and Mac's, but PC-only/Mac-only solutions are acceptable.

• Copy a file from source directory to target base directory and maintain source path

  - by Citizen Dos

  Forgive me, I am probably not using the right terms to describe the problem and misunderstanding the most basic usage for a couple of common commands. I have a simple find statement that is locating files that I want to copy. I want to tack on the -exec cp {} and have cp copy the file from the source directory to a new base directory, but include the full path. For example: "find . -name *.txt" locates /user/username/projects/source.txt "cp {} [now what?]" copies the file to /user/newuser/projects/source.txt
