• GNOME/KDE Linux entirely in RAM?

  - by František Žiacik

  Hi. I'd like to have very responsive linux but I also like modern, elegant and functional desktops like gnome or kde, not the lightweight ones like xfce or lxde. Once I tried PuppyLinux and was impressed by the responsivity when I clicked an application. In my Ubuntu, it bothers me much when I click chromium and must wait 5 seconds of disk flashing until main window appears. Or evolution or anything else. Is it possible to make GNOME or KDE run entirely in RAM like PuppyLinux (of course, I mean frequently used applications and services, not all) if you have enough of it? I don't care if boot time is longer. I tried using "preload" but it didn't help much.

• Host a SSTP VPN Server on Windows 8

  - by Maarten

  I have a small server computer running Windows 8 at home. Currently it is hosting a PPTP VPN server using the build-in Windows 8 functionality for that. What I would want is something more secure, like an SSTP VPN server. However, I can't find any functionality of windows 8 or 3rd party software that can HOST a SSTP vpn server on Windows 8. I've only seen Client stuff and vpn pass trough services via google, all which i don't want/need. The only HOST stuff i find via google is the PPTP i set up currently. Is there any way of hosting a SSTP VPN server on my home machine? Thanks in advance, Maarten

• Why do some web servers not respond to icmp requests?

  - by John Himmelman

  What is the purpose of blocking/dropping inbound ICMP traffic on a public web server? Is it common for it be blocked? I had to test if a server was accessible from various locations (tested on various servers located in different states/countries). I'd rely on ping as a quick & reliable method of determining if a server was online/network-accessible. After not receiving a response on a couple boxes, I tried using lynx to load the site, and it worked.

• Making the most of dual channel DDR2: how do I arrange the sticks?

  - by andrz_001

  I've searched online, but I can't find anything definitive that will put me at ease. I turn to superuser. This is how I have the RAM sticks arranged now: To make the most of the RAM and the dual channel capability, it occurred to me that perhaps I have the sticks arranged incorrectly. Should I move the stick in the DDR2_2 slot one over--to the adjacent, red slot? I appreciate any suggestions. (BTW, can something in BIOS tell me whether I'm running at "optimal" memory speeds??) edit: I'm running Windows XP SP3, 32-bit. Thanks.

• Terminal Server/Win2K3: Users can't write to their My Documents or Temp folders

  - by Tim Sullivan

  I have a situation where a bunch of users are running our software on a Terminal Services machine on Windows 2003 Server. I've removed most permissions from the User group, but made sure they all have the appropriate permissions for their own application folders, as well as for their Documents and Settings folder. For some reason, even though everything seems to be set up properly, users can't create or delete files from their My Documents, Temp or other D&S folders. Whatever could be going on? I thought this was going to be straightforward, but clearly it's not! :-) Thanks for any help!

• Installing Wordpress - constant PHP/MySQL extension appears missing

  - by Driss Zouak

  I've got Win2003 w/IIS6, PHP 5 and MySQL installed. I can confirm PHP is installed correctly because I have a testMe.php that runs properly. When I run the Wordpress setup, I get informed that Your PHP installation appears to be missing the MySQL extension which is required by WordPress. But in my PHP.ini in the DYNAMIC EXTENSIONS section I have extension=php_mysql.dll extension=php_mysqli.dll I verified that mysql.dll and libmysql.dll are both in my PHP directory. I copied my libmysql.dll to the C:\Windows\System32 directory. When I try to run the initial setup for WordPress, I get this answer. I've Googled setting this up, and everything comes down to the above. I'm missing something, but none of the instructions that I've found online seem to cover whatever that is.

  My university assigned me to theorizing a data center for an Web Hosting company. The company should provide the following services: Shared WebHosting; Dedicated Servers; VPS (Virtual Private Server); The bandwith (as resquested) is limited to 10 Gbps. Is there any good book / other info I can read (max 100 pages) about how to design a good data center for hosting, what are the best practices and what should be done from a (logical) network perspective, what security policies should be implemented and how the data center should be built (physically)? Thank you ;)

  Hi, Do you know any software or compilations that you recommend to handle drivers and codecs for newly formated computer?

• Is it possible to combine two internet connections to increase performance?

  - by cornjuliox

  I've got a small home network, 3 PCs plus a laptop or two when the relatives come to visit, connected to a single cable internet connection. Now, as soon as everyone starts using the 'net the performance starts to suffer and if the load is heavy enough nobody can get anything done and everyone complains. At one point it was so bad that only one of us could use it at a time. I was researching possible solutions to this problem and I heard that internet cafes that utilize 2 internet connections, possibly from different providers, and have some sort of router that allows them to split the traffic between the both of them, with online games going through one and web traffic going through another. Is this possible? What is the technical term for it, and can/should it be applied to a home network setup or is there another solution to this problem?

• Why is my hosts file not working?

  - by elliot100

  I've been using the hosts file to for local website development, and it's recently stopped working. No entries other than localhost resolve. I've simplified to test, so it now contains only 127.0.0.1 localhost ::1 localhost 127.0.0.1 test.dev localhost responds to ping, test.dev does not. The file is called hosts with no extension It has no trailing spaces It's saved in C:\WINDOWS\System32\drivers\etc which matches the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath Oddly, despite UAC being on, I can edit, delete and save the file without admin permissions No proxy is being used, PC is not connected to network for testing Stopping the DNS Client service seemed to resolve the issue for a few minutes, test.dev briefly resolved but doesn't any more. Only firewall is Windows' Machine has been restarted. Is there anything else I should try?

• Cannot connect to telnet server

  - by BloodPhilia

  So, I can't use telnet to connect to any server but it works fine from a different computer. It just says it can't connect. I tried the following things: Disable firewall and AV protection. (Basically, there was no security feature left online) Telnet is set to "Trusted" in my AV protection. (Kaspersky Internet Security 2011) Using Putty to telnet, but apparently Putty's connection is also inhibited. (Says it can't connect to host) Disabling the telnet client in Control Panel and then re-enabling it. (Windows 7 Ultimate) hosts file is clean. Checked for nasties using MBAM and KIS 2011 as well as going though my HijackThis logs, nothing found. I can connect to the same machines/servers through the web browser, ping, tracert, etc. Only telnet seems to be blocked. Any other thoughts?

  - by black sensei

  I've installed netbeans which comes with glassfish. i just got a book about glassfish and i wanted to try.the first surprise is the time it took to the admin page to load. i've found on serverfault and by googling that the server is making call to external resource on the network on online (not sure about that). but the adding of the java options didn't speed up the loading of the admin page. how to work around it? i've heard so good about glassfish that this leaves me perplexed. thanks for reading and for helping.

• How can I uninstall a clustered SQL instance if the cluster has been destroyed?

  - by Bob

  First time going through this scenario, and apparently I did it very wrong. On the DB servers I deleted the cluster group that held SQL and Reporting Services. I then destroyed the cluster. Then I tried to uninstall SQL. No dice. SQL still thinks its part of the non-existant cluster and will not let me uninstall it. I went into the Maintenance menu of the SQL setup and tried to Remove Node...nope. Unless I find a way out of this I will have to rebuild the OS if I can't get SQL off the box.

• Fastest web server for serving static content

  - by Swader

  Hello, I'm optimizing our system for some faster static content delivery, and was wondering if anyone has any proper experience with the fastest web servers out there for such a purpose. From the three main candidates I've considered, Nginx, Cherokee and Lighttpd, each seems to have its own problems - but the reports I've read online are somewhat biased and lean towards whichever server the user is currently using. Any ideas on where to see a proper benchmark for this specific purpose, or at least a non-biased list of pros and cons? Any personal experiences and pitfalls I should be vary of? Thanks Edit: Serverfault.com gave the answer as nginx. I'd still like to hear some developer thoughts from this end of the universe.

• How to bulk mail-enable contacts from AD in Exchange 2007?

  - by George Hewitt

  Hello, We have several thousand 'contacts' setup in AD already for a faxing system. We're migrating to an online fax provider that uses e-mail rather than plain old telephone. So, we've bulk edited all the AD records so that the 'mail' attribute is populated with the right e-mail address in the right format. Now, how do we enable these contacts within Exchange 2007? I've looked through http://technet.microsoft.com/en-us/library/bb684891.aspx but that only seems to talk about manually editing the CSV output to specify the external addresses. AD already knows the external e-mail addresses - I just need the info in Exchange! Any thoughts?

• Distributing application updates using SCCM 2007

  - by theraneman

  Hi all, If there are any System Center Config Manager (SCCM) users out there, please clarify my doubt here. I have used the ConfigMgr console to distribute a custom application to a client machine. Now I need to distribute some updated files of that application. Isnt's it possible to add those files in the same package source used earlier and advertise again? Or should I use the SCCM software update section for this? Not sure if its only me, but the Software distribution process looks much easier than the Software Updates process in SCCM 2007. Please do let me know if there any online tutorials which explain how to update a custom application. Any help much appreciated.

• email archive for multiple users

  - by evanmcd

  Hi, I'm moving a web site from one server to another, and am realizing that I need to move the name servers for the domain as well (they are set to the current host, not to the registrar). So, knowing that email services will stop as soon as I switch the DNS, I'm scrambling to figure out how to archive and make available email data for folks that have mostly been using webmail for the past few years, and may not even have a computer on which to install a client to download the mail to. What does one do in this situation? Thanks for any help offered! Evan

• modprobe ndiswrapper - not found

  - by David

  I'm trying to use ndiswrapper on a Slackware 12 (I think) box, but I'm running into a problem with modprobe. Everything I find online says that it should be working, but for some unknown reason it isn't. Here's what I've done so far: Installed ndiswrapper (latest tarball, make, make install) Ran ndiswrapper -i on the WinXP driver for my USB wireless card Ran ndiswrapper -l which tells me the driver is present and the device is present (lsusb also confirms the device is present) Ran ndiswrapper -m which put an alias for wlan0 in /etc/modprobe.d/ndiswrapper.conf Ran depmod -a Ran modprobe ndiswrapper which tells me "FATAL: module ndiswrapper not found" Ran modprobe -l which shows no listing for ndiswrapper I even tossed in a reboot or two while trying various combinations of the above, still nothing. So naturally ifconfig wlan0 up isn't working because the device isn't being created, presumably because the module isn't loading the driver. Does anybody have any suggestions? Everything points to the notion that this should work fine, but modprobe just isn't able to find what it needs. Have I missed an important step?

• TCP/IP performance tuning under KVM/Qemu

  - by vpetersson

  With more and more companies switching to public cloud services, I'm curious what you guys' thoughts are on TCP/IP tuning in the cloud. Is it worth bothering with? Given that you don't have access to the host-server, you're somewhat limited I presume Let's say for the sake of the argument that you're running three MongoDB-servers in a replica-set on FreeBSD or Linux that all sync over an internal network. I'd also be curious if anyone made any actual performance benchmarks to back up their arguments. I benchmarked the various network drivers available for KVM/Qemu here, but I'm curious what the gurus here suggest to tune further. I started playing around a bit with the tuning-recommendations as suggested over here, but interestingly enough I saw a decrease in performance, rather than an increase, but perhaps I didn't fully understand the tweaks. Update: I did a few more benchmarks and posted the result here. Unfortunately the result wasn't really what I expected.

• Why does PsExec hang after successfully running a powershell script?

  - by Matt

  The script is fairly straight forward. Simply tries to start a bunch of windows services. Execution locally works fine when on the target machine. The script is actually executing fine as well when done via PsExec, it just never returns until I hit the "enter" key on my CMD prompt. This is a problem, because this is being called from TeamCity, and it makes the Agent hang waiting for PsExec to return. I've tried the following: Adding an exit and exit 0 at the end of the Powershell script Adding a < NUL to the end of the PsExec call, per the answer in this SF question Adding a > stdout redirect This is how I am actually calling psexec: psexec \\target -u domain\username -p password powershell c:\path\script.ps1 No matter what I do, it hangs until I the locally on the cmd prompt. After I hit enter, I get the message: powershell exited on target with error code 0.

• web (server) based password manager

  - by laurens

  Hi all! I know there have been a few topics here about password managers but I read them all and did not really find what I'm looking for. What I'd need is a free or cheap (most password mgr software is $500 for 20+ users, exaggerated!) multi-user password manager, highly preferable web-based so that we can host it on one of our local server, of Hyper-V VM's. So: -free or cheap ( <100$) -multi-user of groups -web based -not very hard to install I tried a few, one very expensive, one I did not get to work- Web Keepass Manager This works with tomcat and probably conflicts with our IIS 7.0 or 7.5 PS: thus, nothing online (!) it has to stay local Thanks in advance!
