• Seamless Remote Windows on Linux Client

  - by prestomation

  I really like the RemoteApp features of Windows Server 2008 Are there any solutions for similar functionality for Linux clients and a Windows server? We have users that are running Linux on the desktop and rdesktop to a Windows server, mostly for Outlook. It would be nice if Outlook could behave more seamlessly. From what I can tell rdesktop doesn't do that yet, it only implements RDP 5. I've also seen "SeamlessRDP" from Cendio, which is an extension to rdesktop, but I can't get it to work. I think it doesn't work in Vista, but that is just a guess. Any ideas? And thanks in advance. EDIT: I emailed Cendio and they confirmed SeamlessRDP doesn't work with Server 2008 for unknown reasons. It appears there is no way to do this with a 2k8 server. It's either windows clients with RemoteApp or using a pre-Vista OS with seamlessrdp

• Linux command to concatenate audio files and output them to ogg

  - by hasen j

  What command-line tools do I need in order to concatenate several audio files and output them as one ogg (and/or mp3)? If you can provide the complete command to concatenate and output to ogg, that would be awesome. Edit: Input files (in my case, currently) are in wma format, but ideally it should be flexible enough to support a wide range of popular formats. Edit2: Just to clarify, I don't want to merge all wmas in a certain directory, I just want to concatenate 2 or 3 files into one. Thanks for the proposed solutions, but they all seem to require creating temporary files, if possible at all, I'd like to avoid that.

• Force the computer to always use current display settings

  - by sazpaz

  So I'm having a terrible black screen problem with my new installation of Windows 8. The screen basically goes to black every time I turn it on or sleep, or connect to an external or monitor. I dont really know what steps actually cause the problem and cant seem to figure what steps allow the screen to come back, besides forcing restarts, going to sleep and waking up, and smashing Win + P. I have a strong feeling it's because the Switchable graphics I have (Intel HD + Radeon 5060), so I'm looking for a way to make the computer always use a specified mode (i.e the current mode I'm on, that does show stuff on the screen) and force it to use it everytime? Any ideas? EDIT: I've Installed all the latest drivers I've found. Tried most of the solutions around the web for this problem. Updated the BIOS to UEFI (from HP Support Assistant), etc. Laptop is an HP- Envy 14

• Windows Server firewall asking for advice

  - by George2

  Hello everyone, I have Windows Server 2003/2008 machine, and I deployed some application on this machine. I want to put this machine in a sandbox environment, which means I want this machine to be able to access only proxy/gateway, its private used SQL Server database server, and I want to avoid network access from this machine to other machines in lab server room. Any easy solutions? BTW: my current environment is, I have a server which runs some Beta software in a Lab server room. It connects internet through proxy/gateway. Since the software is Beta, I want to reduce the risk of being hacked from internet and controlled by hacking sofwtare to attack my other servers in the same Lab server. thanks in advance, George

• Custom resolution - Windows 7 - no drivers

  - by Vytautas Butkus

  I'm having some problems with my VGA card. When I enable my VGA drivers and boot windows up they crash and I get message that the problem occured with atimdag.sys drivers or smth like that. I'm gettin BSOD all the time, unless I go to control panel and I disable drivers manually. I can live with disabled drivers just fine(I'm already used to it in quite some time) but the annoying problem is my display resolution. I can not set my res to anything higher than 1024x768. I was wondering if it's possible to change resolution to my native displays resolution without drivers? I've been trying to find something that would work w/o drivers, but with no luck(I've found many of solutions how to do it with working drivers, but as you know I can not enable my drivers). So please, maybe someone could help me and tell me how to set custom resolution?

• How to prevent any files from being copied onto the Desktop?

  - by Kaushik Gopal

  Gentlepeeps, Is there any solution to prevent copying of files onto the desktop? My folks and i currently have one super-common-comp in our place. And when all of the laptops are busy, we tend to do some quick surfing on this comp. I prefer to keep things freakishly organized in this comp and one thing i hate is having those off-shoot irritating forwarded downloads on my desktop. Is there some way to restrict files from being copied onto the desktop? I tried making the administrator user's desktop folder as read-only :P . That doesn't solve the problem. Any other ideas/software/solutions? cheers.

• Network wide rule to forwared IP address

  - by Patrick

  Hi, we have a virtual machine which hosts a web based bug tracker in our network which is reached internally via e.g. 192.168.1.5:9800. From the outside we made a port forwarding in our firewall so that the web site can be reached via e.g. 72.10.10.10:9800. Now that works fine but the problem is that we got different IP addresses to reach the same service depending if we are in the office or at home and when the service sends out an email the link doesn't always work :) So we are looking for a solution to fix it. One could be to make a rule in out firewall that all communication to 72.10.10.10:9800 is forwarded to 192.168.1.5:9800... If that's possible that is considering it's an IP address + a port. The reason we used a port is because we only got one static public IP address but multiple virtual web appliances. Thanks for any suggestions or solutions :) Patrick PS: The network is a Win 2008 R2 domain by the way

• Sharp flat panel scaling with Nvidia drivers

  - by Brecht Machiels

  I have a Samsung 226BW flat panel with a 1680x1050 native resolution. As my PC is rather dated (Athlon XP 2600+ and GeForce 6600 GT), I need to run more recent games (but still old) on a lower resolution. Unfortunately, scaling low resolutions to 1680x1050 results in a very blurry image (bilinear scaling). I have created a custom resolution of 840x525 in the Nvidia control panel. Technically, this resolutions allows perfect upscaling to 1680x1050 without the need for bilinear interpolation. Unfortunately, the Nvidia driver always seems to do bilinear scaling, again resulting in a blurry image. However, I seem to remember that I did obtain crisp images using this resolution in the past (before a Windows re-install). Maybe only some driver versions support integer upscaling without bilinear filtering? Or perhaps there are other solutions?

• How to ignore query parameters in web cache?

  - by eduardocereto

  Google Analytics use some query parameters to identify campaigns and to do cookie control. This is all handled by javascript code. Take a look at the following example: http://www.example.com/?utm_source=newsletter&utm_medium=email&utm_ter m=October%2B2008&utm_campaign=promotion This will set cookies via JavaScript with the right campaign origin. This query parameters can have multiple and sometimes random values. Since they are used as cache hash keys the cache performance is heavily degraded in some scenarios. I suppose there's a not so hard configuration on cache servers to just ignore all query parameters or specific query parameters. Am I right? Does anyone know how hard is it in popular web cache solutions, to create ? I'm not interested in a specific web cache solution. It would be great to hear about the one you use.

• Single sign-on for intranet?

  - by Jason Swett

  I'm trying to set up a single sign-on for my intranet. I've found a couple solutions online but I'm not sure if they apply to my particular situation. I have several subdomains on the same server. One level of user should be able to access all subdomains and another level of user should only be able to access some subdomains. Signing into one subdomain should make it so you don't have to log into any others. Can anyone point me in the right direction? I'm on Ubuntu using Apache.

• zfs rename/move root filesystem into child

  - by Anton

  Similar question exists but the solution (using mv) is awful because in this case it works as "copy, then remove" rather than pure "move". So, I created a pool: zpool create tank /dev/loop0 and rsynced my data from another storage in there directly so that my data is now in /tank. zfs list NAME USED AVAIL REFER MOUNTPOINT tank 591G 2.10T 591G /tank Now I've realized that I need my data to be in a child filesystem, not in /tank filesystem directly. So how do I move or rename the existing root filesystem so that it becomes a child within the pool? Simple rename won't work: zfs rename tank tank/mydata cannot rename to 'tank/mydata': datasets must be within same pool (Btw, why does it complain the datasets are not within same pool when if fact I only have one pool?) I know there are solutions that involve copying all the data (mv, or sending the whole dataset to another device and back), but shouldn't there be a simple elegant way? Just noting that I do not care of snapshots at this stage (there are none yet to care of).

• looking for a clean way of how to bring down a ftp server for maintenance

  - by harald

  hello, i'm currently thinking of a clean way of how to bring an ftp server down for maintenance. i wonder, if anybody out there could give me some hints of how to solve this: i don't want to interrupt any current uploads, but want to block any new connects / uploads and wait, till uploads have finished, before taking down the ftp server is there a way of dynamically prevent user-logins and show a message eg.: "ftp currently down for maintenance" when a user tries to log in? are my thoughts on this very uncommon or how do others handle this -- i feel, that just halting ftp server and killing any current uploads is not the right way for this ... i use proftpd (with SQL backend) btw, maybe there are some specific solutions for this -- or are there any generic tools to achieve this? many thanks!

• Does liquid cooling mean I no longer need to dust my machine?

  - by Starkers

  I've got two long haired cats, a dog and I live with a smoker. I use my computer pretty much all day everday, and though I put it to sleep in the night, those fans are constantly going during the day. In just 6 months the rear fans have so much hair wrapped around them it looks more like something from a vacuum cleaner rather than electronic equipment! Due to this, I'm interested in liquid cooling. However, it appears that liquid cooled systems have fans and liquid cooling? Are those just hybrid solutions? They wouldn't really help my situation. There does appear to be fanless systems that use a radiator to dissipate heat. If I implemented one of these could I seal up the vents on my PC and never have to dust it again? Is there a disadvantage to fanless liquid cooling? I don't need to overclock at the moment but I ever want to push my components will fanless liquid cooling be pretty rubbish?

• accessing a web server from the LAN and WAN

  - by jessh

  My router does not support loopback. In order to view a webpage on my server, I either have to type in the local ip (192.168.1.201), or be on another network. What are my options for making this easier? Here are some possible things: Route all web traffic through an external proxy (seems to be overkill) Run my own DNS server (where to start?!) Buy a new router that supports loopback. Surely there is another way that I can use my laptop on the LAN and the WAN by typing in my domain more easily than these solutions.

• What are the benefits of running chef-server instead of chef-solo?

  - by strife25

  I am looking at automated deployment solutions for my team and have been playing with Chef for the past few days. I've been able to get a simple web app up an running from a base Red Hat VM using chef-solo. Our end goal is to use Chef (or another system) to automatically deploy application topologies to the cloud as we run builds. Our process would basically run like so: Our web app code, dependencies, and chef cookbooks are stored in SCM A build is executed and greats a single package for images to acquire and test against The build engine then deploys new cloud images that run a chef client to get packages installed. The images acquire the cookbooks from SCM or the Chef server and install everything to get up and running What are the benefits and/or use cases for getting a Chef Server running? Are there any major benefits to have a Chef Server hold and acquire the cookbooks from SCM vs. using chef-solo and having a script that will pull the cookbooks from SCM?

• VPN authentication and MAC addresses

  - by zakk

  I have to set up a VPN (various clients connecting to a web service on a server, which is also the VPN server) and I want to make sure that no user will share his/her credentials with third parties. I know that this problem is not solvable completely, but I'd want to set up some additional security checks... Some idea I have: 1) An additional check on MAC address, but... are MAC addresses preserved thru VPN? 2) Some kind of extra identification of the client (User Agent, open ports, I want to make sure that is the very same client I authorized). 3) I would like to avoid commercial solutions like a security token... I realize it would be the perfect solution, but it will be to expensive, I suppose... Do you feel that these options are viable? Do you have any other ideas? Thanks in advance for your replies!

• Windows 8.1 clean install keeps failing with Oxc0000005 error

  - by joaocandre

  I'm encountering the error Oxc0000005 when making a clean install of Windows 8.1 x64 on a Samsung 840 SSD. I don't know where the error is coming from, I'v already tested several solutions/workarounds I found online and nothing seems to work. The SSD is healthy, I can install Linux (Ubuntu) on it, but apparently the Windows install reports the drive as "locked" when trying to "refresh" the install. According to diskpart, however, the SSD is not in read-only mode, so I don't understand what is going on. I had Windows 8 installed before formatting the drive.

• Domain connection shows as "unauthenticated"

  - by gareth89

  I have seen various different questions for this problem floating around but either the circumstances arent the same or the solution doesnt work so thought i would post it to see if anybody has any suggestions. Various domain PCs and laptops appear to randomly give the connection name of "lewis.local 2(Unauthenticated)" - lewis.local being our domain - and provides an exclamation mark where the network type logo is normally shown. This also appears to happen every time connecting via vpn. Our setup is: 2 servers both running windows server 2003 R2 (x32) main server has AD, DNS and DHCP installed IPv4 on approx 30 client machines (some wired, some wireless) If anybody has any thoughts on solutions i would appreciate it. I have tried removing all but AD server roles, resetting all of the systems and nothing. It doesnt prevent anything from working just like a domain connection most of the time however it is getting fustrating! Also dont know if it could have anything to do with it but the DHCP server seems to have quite a long lead time on issuing the IP address to the client.

• Unknown Host Error, is this a registrar problem or a host problem?

  - by jerrygarciuh

  Hi guys, I am dealing with a barrel of weasels on this one. Ad agency registered the domain in mid-August with Network Solutions. 72 hours ago I updated the DNS to point to a host provided by an associate of the client whose credentials are dubious. The DNS servers are at NETSONIC.NET (NS1 and NS2) and respond to ping no problem. I can FTP to the server using its IP but the name is no go. The name is also no go for tracert and ping: tracert voodoobbqfranchise.com Unable to resolve target system name voodoobbqfranchise.com. ping voodoobbqfranchise.com ping: unknown host voodoobbqfranchise.com I called NetSol and of course their tier one guy swears it must be the host but I insist that an unknown host must be a NetSol issue. Otherwise we'd get somethng like an httpd_conf error after being routed to the Netsonic server. Am I right? Is this an issue at the registrar? TIA JG

• Ubuntu server failing daily

  - by deanvz

  Symptoms: Server becomes unresponsive - Increase in load, all services stop Loss of connectivity - Ping/SSH Flush MySQL hosts after reboot - As MySQL refuses new connections Intermittent Apache crashes Generally happens early morning hours - 2 days of the week are however excluded Changes made: Updated the OS - to Ubuntu 10.04.4 LTS Not sure if the MySQL server was also updated in the process Current MySQL version - mysql Ver 14.14 Distrib 5.1.63, for debian-linux-gnu (x86_64) using readline 6.1 Updated Plesk from 10.4.4 Update #47 to 11.0.9 Update #23 Rebooted on almost daily basis All crons stopped for the times corresponding to the server crashes Created a MySQL log to monitor the lock times on queries Possible causes: Failing hardware Incorrect software configuration (MySQL, Apache etc) Responsibilities: Small webserver Runs our billing system - WHMCS Responsible for CRONs Bulk-email solution - No delivery times coincide with server crashes Proposed solutions: Move machine over to VM Format and restore the Plesk server backup and take it from there? Side notes: Seems to be a general Apache failure across all our linux servers - Intermittent problem Are we doing something fundamentally wrong in the Apache config? (I understand that this is a secondary question, just making sure that it isnt possibly holding any relevance)

• Looking for FTP server that allows user management from database

  - by hughesdan

  I'm planning a server application that will handle files uploaded via FTP. The application must parse text documents that it receives and write them to a database (most likely a document-oriented database like Mongo). And the application must also relay all large binary files it receives to Amazon S3 for storage and hosting. I'd like to manage all aspects of the FTP server programmatically. For example, when a user registers via a web page the application should be able to create the user account in the database and provision a directory on the server for receiving files. I'm using a Linux server but am otherwise open to considering any programming language or framework. I experimented with VSFTPD but didn't like the way the application relies on config files and the creation of users and directories via the command line. Can someone please recommend what server framework I should consider? I'm a little biased toward solutions that leverage Javascript/Nodejs or Python. However, I'm open to anything that can run on a Linux box.

• How to add the Windows defender into Windows Explorer's right click menu to scan a particular drive/folder/file on demand?

  - by avirk

  There is no option in Windows Explorer to scan a particular drive (or file) on demand by right clicking on it in Windows Explorer as we had in Windows 7 with Microsoft Security Essentials or like other antivirus solutions. I know we can run a custom scan for the particular drive or specific folder but that process is too lengthy and time consuming. The guide How to Add a "Windows Defender" Cascading Desktop Context Menu in Windows 8 explains how we can add Windows Defender in the desktop right click menu, so I'm curious, is there a way to add it in the Windows Explorer right click menu to launch a search whenever I need to?
