• Apachebench on node.js server returning "apr_poll: The timeout specified has expired (70007)" after ~30 requests

  - by Scott

  I just started working with node.js and doing some experimental load testing with ab is returning an error at around 30 requests or so. I've found other pages showing a lot better concurrency numbers than I am such as: http://zgadzaj.com/benchmarking-nodejs-basic-performance-tests-against-apache-php Are there some critical server configuration settings that need done to achieve those numbers? I've watched memory on top and I still see a decent amount of free memory while running ab, watched mongostat as well and not seeing anything that looks suspicious. The command I'm running, and the error is: ab -k -n 100 -c 10 postrockandbeyond.com/ This is ApacheBench, Version 2.0.41-dev <$Revision: 1.121.2.12 $> apache-2.0 Copyright (c) 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Copyright (c) 2006 The Apache Software Foundation, http://www.apache.org/ Benchmarking postrockandbeyond.com (be patient)...apr_poll: The timeout specified has expired (70007) Total of 32 requests completed Does anyone have any suggestions on things I should look in to that may be causing this? I'm running it on osx lion, but have also run the same command on the server with the same results. EDIT: I eventually solved this issue. I was using a TTAPI, which was connecting to turntable.fm through websockets. On the homepage, I was connecting on every request. So what was happening was that after a certain number of connections, everything would fall apart. If you're running into the same issue, check out whether you are hitting external services each request.

• SCVMM 2008 R2 problems migrating VM from VS2005 to Hyper-V host

  - by Scott Ivey

  I have System Center Virtual Machine Manager 2008 R2 installed, and have a Hyper-V R2 host and a Virtual Server 2005 host. I'm trying to migrate my machines from the VS2005 host to the Hyper-V host, and keep getting the following error... VMM is unable to complete the requested file transfer. The connection to the HTTP server myserver.mydomain.local could not be established. (Unknown error (0x80072efd)) Recommended Action Ensure that the HTTP service and/or the agent on the machine myserver.mydomain.local are installed and running and that a firewall is not blocking HTTPS traffic. (Note - migrations between Hyper-V hosts managed by the VMM server work fine - my problem is just going from VS2005-Hyper-V hosts) I have no firewalls turned on on either of the servers, and no firewalls in the middle. I've looked all over for answers to this problem, and am getting nowhere. All the articles I find when searching are talking about either V2V or P2V - and i'm just trying to do a straight migrate VM. I've tried rebooting the boxes, changing the BITS SSL port number, restarting services, triple-checking firewalls, etc. Does anyone have any good suggestions as to how I can resolve this problem?

• Why isn't ICMP routing with iptables nat routing

  - by Scott Forsyth - MVP

  I'm using iptables on Ubuntu server to route a public IP to a private IP. I want to nat all traffic, including 80, 443 and ICMP. However, it appears that ICMP isn't routing. I have a steady ping going to the public IP and it never stops, even with NAT pointing to a bogus IP. Here are the rules that I'm using: iptables -t nat -I PREROUTING -d 206.72.119.76 -j DNAT --to-destination 10.240.5.5 iptables -t nat -I POSTROUTING -s 10.240.5.5 -j SNAT --to-source 206.72.119.76 I tried with rules for ICMP specifically, but no such luck: iptables -t nat -I PREROUTING -d 206.72.119.76 - icmp --icmp-type echo-request -j DNAT --to-destination 10.240.5.5 Any ideas?

• Getting SMB file shares working over a PPTP VPN

  - by Ben Scott

  I'm having issues getting SMB file shares working over a PPTP VPN. The server setup consists of a security device (DrayTek V3300) which passes the PPTP authentication to a SBS2003 server running RRAS. The server is the DC and provides DNS and WINS, the single NIC's name server is set to the NIC's IP (192.168...), and DHCP on the DrayTek sets the server IP as the DNS. If I create a new VPN connection in Win7, leaving everything as default apart from the server, username, password and domain, I can: ping everything by IP address resolve IPs with nslookup using their fully-qualified name, as in nslookup fileserver.mydomain.local ping machines by fully-qualified name, as in ping fileserver.mydomain.local However if I try to access a file share: within Explorer, I get "Windows cannot access ..." with "Error code: 0x80004005 Unspecified Error", using net use z: \\fileserver.mydomain.local\share, I get "System error 53 has occurred. The network path was not found." If I add the machine name to my HOSTS file I can use the file share, which is my last-ditch workaround, but I have a number of VPN users and would rather a solution that doesn't involve me trying to hand-edit system files on computers half a country away. If I set the WINS server explicitly in the connection's IPv4 settings I don't have to use the FQN to ping the machine, but that doesn't change anything else. EDIT: The PC I'm having the issue on is running Win 7 Home Premium. After more testing I actually have two other PCs that work, one W7HP, one XP Home, and another Vista PC that doesn't work (not tested as much as the others), all four on the same internet connection (behind the same router). All of them were tested with a straight-forward, all defaults, new VPN configuration.

• Oops, no RSA or DSA server certificate found for 'server.host.name:0'?

  - by Scott Warren

  I'm setting up a new web server that hosts a dozen virtual hosts on Ubuntu 12.4 using Apache 2.2.22 with one config file per site. I created all the configuration files all at once and ran a2ensite * to enable them all at once. When I reloaded the configuration it failed and after restarting apache I found the following error message in my error.log: Oops, no RSA or DSA server certificate found for 'server.host.name:0'?! Most of the results for this error message are years old that don't fix the problem or are bugs that have been fixed https://issues.apache.org/bugzilla/show_bug.cgi?id=31709

• RoboCopy fails with "the specified network name is no longer available"

  - by Justin Scott

  We have a scheduled task that runs robocopy periodically to mirror a rather large folder structure from one server to another (thousands of folders, 100,000+ files, 50+ GB in size). There is a share on the receiving server where the mirror gets stored. We're running the task from the origin server connecting out to the share on the receiving end. Both servers run Windows Server 2003 and are connected to the same network switch (100Mbps). The process will sometimes complete all the way through without error. More often than not, however, at some point during the process (seems random as to where), robocopy will fail with the error The specified network name is no longer available. It will wait 30 seconds and try the file again and eventually give up after a number of retries. Process will repeat at the next schedule interval and may complete... or not. When this occurs I am not able to access the share at all on the destination server from anywhere on the network for up to 30 minutes. There is nothing else on the network using this share. My question is what does this error mean specifically? Why is the share "dropping off" and becoming inaccessible? Is there a way to prevent it and get the file mirroring to be more stable?

• TFS 2010 : Unable to add Project to a collection

  - by Scott

  This morning I'm trying to setup Team Foundation Server 2010 to demo for my team. As this is just a demo, I thought I would install it on my Windows 7 machine which also serves as my development machine. My development machine uses Visual Studio 2008 Team Suite. I installed Team Explorer 2008 and then reapplied SP1. Finally I installed and setup TFS 2010. TFS by default gave me administrator privileges. I started up Visual Studios, and connected up to the Collection just fine. However, I'm unable to create a new project and get the follow error message: "TF30172: You are trying to create a team project either without required permissions or with an older version of team Explorer. Contact your project admin..." To check to permissions, I used my home computer which is running Visual Studio 2010. On this machine I was able to connect up to the same TFS instance and create a project no problem. So it looks as though it is a team explorer problem, but everywhere on the web people are saying not only am what I'm trying to do possible, but they have done it themselves. What am I missing to add a project to TFS 2010 under Visual Studio 2008?

• Outlook 2007 won't close

  - by Scott Weinstein

  I use Outlook 2007 at home as an IMAP client and RSS feed reader. I have a problem that when I close outlook, the window exits, but the process remains running. This prevents me from opening outlook again and on Win7 prevents rapid shutdown of my computer. How can I have Outlook 2007 exit for real? Edit: Here's what the addins dialog reports Active: None Inactive: MS Outlook Mobile Service, MS VBA for Outlook, OneNote Notes for Outlook Items, Outlook Change Notifier, Windows Search Email indexer.

• ClearOS - how to create a site to site VPN between two ClearOS boxes?

  - by Scott Szretter

  I plan on setting up some ClearOS boxes at several sites, and would like to set up site-to-site VPN between the remote sites and a main site (all running ClearOS enterprise 5.2sp1 / latest version). I have found references for how to set up ClearOS to VPN in to devices such as cisco for IPSEC, and others with PPTP. But for these methods it did not mention how you might configure 2 ClearOS boxes to talk to each other ipsec or pptp. I also saw documentation on installing OpenVPN and using the OpenVPN client software to VPN in to the ClearOS box. I will probably use this for individual users to VPN in, but I have some small sites ( 1 to 10 users) that will have their own ClearOS box and need to create a site to site VPN link back to the main site's OpenVPN box. Is this possible, can you point me to docs, or other info or basically, how? A couple updates: I did find a thread that asks the same basic question, where the user has a vpn set up between the two clearos machines (after installing ipsec vpn modules), just not transporting traffic between the LANS - and the very last post claims you have to edit some files (/etc/ipsec.conf) and set leftnexthop rightnexthop values to %direct. After that, it's supposed to work. Could it be that simple? I also posted to clear foundation, and they pointed me to some documentation for setting up ipsec unmanaged vpn. This looks pretty good, but, I will most likely need to figure out how to handle a dynamic dns type setup at least on one end. Also, what does it mean by multi-wan? Finally, what happens when a vpn connection goes down exactly - someone has to reboot the box or ?

• Windows 7 Office 2007 GPO install

  - by Scott

  I have a GPO that works fine for installing Office 2007 Pro Plus on Vista and XP but when it installs Office on Windows 7 somehow the office key does not get entered via the customized msp, and needs to be entered manually. Has anyone else run into this? Any suggestions for a fix? Its defeats the purpose of remote unattended install if I then have to run around entering the stupid key. edit: I am sorry I should have specified I also have the config.xml file customized already. I have it set to display level none, completion no, suppress modal to yes accept eula to yes, the key put in and the company name and the username variable (%USERNAME%).

• Imagemagick PDF to JPG conversion failing

• SCVMM 2008 R2 problems migrating VM from VS2005 to Hyper-V host

• Windows Explorer is blank

  - by Scott Mitchell

  I am using Windows 7 Utlimate x64. Once a week, or so, when I boot up n the morning and launch Windows Explorer it shows up blank, as the following screen shot show. Clicking on my Computer doesn't load anything. Interestingly, I can go the the Address bar at the top and type in a folder name. This brings up that folder's files and subfolders, but as I drill around the tree of folders on the left only shows the immediate folder and not its siblings. There's no plus icon to expand the folder, etc. My usual "solution" is to reboot, which typically brings everything back to normal, but this is a frustrating remedy. Any idea what's going on and how to fix it? Some Googling turned up this discussion, but the remedy was to uninstall a particular piece of software that I don't have installed (Virtual Clone Drive). Thanks

• Is there a Unix/Linux platform equivalent to Telligent Community?

  - by Scott A. Lawrence

  Telligent Community combines blogs, wikis, forums, and file-sharing capabilities into a single product with single sign-on, using all Microsoft technologies. Is there an equivalent offering that runs on Unix/Linux? Or would I have to pick and choose individual product offerings and figure out another option for single sign-on across them? Are there plug-ins for something like WordPress or MovableType that might add the necessary functionality? A friend of mine is looking to add a "members-only" area to her company's website, and since they're hosted on Dreamhost (and can't afford StackExchange pricing yet), I'm trying to find other options for them.

• Enable RemoteApp Full Desktop programmatically

  - by Scott Chamberlain

  I am writing a powershell script to set up some HyperV VM's however there is one step I am having trouble automating. How do I check the box to allow Remote desktop access from the RemoteApp settings programmatically? I can set up all of my customizations I need by doing #build the secrity descriptor so the desktop only shows up for people who should be allowed to see it $remoteDesktopUsersSid = New-Object System.Security.Principal.SecurityIdentifier($remoteDesktopUsersGroup.objectSid[0],0) $aceTemplet = 'O:WDG:WDD:ARP(A;CIOI;CCLCSWLORCGR;;;{0})' $securityDescriptor = $aceTemplet -f $remoteDesktopUsersSid #get a copy of the WMI instance $tsRemoteDesktop = Get-WmiObject -Namespace root\CIMV2\TerminalServices -Class Win32_TSRemoteDesktop #set settings $tsRemoteDesktop.Name = $ServerDisplayName $tsRemoteDesktop.SecurityDescriptor = $securityDescriptor $tsRemoteDesktop.IconPath = $IconPath $tsRemoteDesktop.IconIndex = $IconIndex #push settings back to server Set-WmiInstance -InputObject $tsRemoteDesktop -PutType UpdateOnly however the instance of that WMI object does not exist until after you have the above box checked. I attempted to use Set-WmiInstance to instantiate and set the settings at the same time but I keep getting errors like: Set-WmiInstance : At line:53 char:16 + Set-WmiInstance <<<< -Namespace root\CIMV2\TerminalServices -Class Win32_TSRemoteDesktop -Arguments @{Alias='TSRemoteDesktop';Name=$ServerDisplayName;ShowInPortal=$true;SecurityDescriptor=$securityDescriptor} + CategoryInfo : NotSpecified: (:) [Set-WmiInstance], ArgumentException + FullyQualifiedErrorId : System.ArgumentException,Microsoft.PowerShell.Commands.SetWmiInstance (also after running the command and getting the error it will delete the instance of Win32_TSRemoteDesktop if it already exited and un-check the box in the properties setting) Is there any way to programmatically check that box or can anyone help with why Set-WmiInstance throws that error?

• How to find and diagnose poorly-performing Firefox addins?

  - by Scott Bilas

  I use a lot of addins in my Firefox. One of them is causing periodic freezes when watching video. Super annoying. Aside from doing a binary search of disabling addins to narrow down the problem (which would take a very long time due to frequency of the freezes), are there any other options? If the problem came from the native app, then I'd just load up a profiler and see where the time is going. But it's all in Javascript. Are there any tools that exist to help figure this out? Maybe some instrumentation I can throw on a few key source files in a local build to help diagnose the problem?

• How do I change OSX package install directory?

  - by Scott

  It drives me nuts that every time I download a binary to run on OSX that it wants to install in system directories. ~/Applications is a perfectly fine place to install and doesn't require blindly authenticating somebody else's binary. Is there a way to change the install directory for packages? On a few I've been able to open the package and edit the plist to install it elsewhere, but that doesn't work universally. I install from source when I can, but it isn't always an option. Is there a good way to force the installer to use ~/Applications?

• How do I effectively use WinSCP on my GoDaddy Dedicated Hosting

  - by Scott

  After being told that Virtual Private Servers would not fit the scope of my project, I have timidly entered the world of dedicated hosting. Unfortunately, this is forcing me how to learn the basics of being a Linux server admin. GoDaddy has a master account for the server. When you use SSH, they want you to use "su" to switch to the root user. Thus far, I have been able to do everything I have needed to thus far via the command line as this root user. However, now I need to upload files to my server. I'm used to using WinSCP to upload files. I can use my general server account to view the files but when I try to drag or create files its says that I cannot because I do not have permission to do so. I have researched the WinSCP documentation and it seems that this "su" function is beyond the scope of the program. How am I to grant myself access to upload these files using SSH? Should I create a user with the proper permissions? I'm happy to do this but thus far I have not been able to make sense of what I have found online. I'm going to try and move forward but any help and/or insight is appreciated.

• Windows 7 64bit keyboard issues

  - by Scott

  I have a Pavilion dv4 notebook running Windows 7 64bit Enterprise edition. This morning I started to notice some really strange behavior in how it handled its built-in keyboard. At random intervals there will be a long delay in key presses, to which some keys will never show and other keys will continue to repeat until you hit the backspace. Other keys get mapped incorrectly to other keys. If I hook up an external keyboard the problem does not appear. Before I reformat the machine and do a fresh install, I thought I would check here to see if anyone has experienced this same issue and if so, how did you fix it?

• Executing Oracle SQLPlus in a Powershell Invoke-Command statement against a remote machine

  - by Scott Muc

  We have a basic powershell script that attempts to execute SQLPlus.exe on a remote machine. The remote does not have Oracle Instant client installed, but we have bundled all the necesary dlls in a remote folder. For example we have sqlplus.exe and dependencies in the directory C:\temp\oracle. If I navigate to that path on the remote server and execute sqlplus.exe it runs just fine. I get the prompt for username. If I go: Invoke-Command -comp remote.machine.host -ScriptBlock { C:\temp\oracle\sqplus.exe } I get the following: Error 57 initializing SQL*Plus + CategoryInfo : NotSpecified: (Error 57 initializing SQL*Plus:String) [], RemoteException + FullyQualifiedErrorId : NativeCommandError Error loading message shared library Thinking that it's potentially a PATH issue I tried the following: Invoke-Command -comp remote.machine.host -ScriptBlock { $env:ORACLE_HOME= "C:\temp\oracle"; $env:PATH = "$env:ORACLE_HOME; C:\temp\oracle\sqlplus.exe } This had the same result. The error code is not very helpful and is extremely frustrating since it does work when I log on to the machine. What is powershell remoting doing that's making this not work?

• Patch Management and System Inventory on a Windows network?

  - by Scott

  What are some good ways to have patch management and systems/hardware inventory for a Windows (Server 2003 or 2008) network? For example, at a minimum knowing the basics for all the machines out on the network such as OS version, patch level, what hotfixes they have, processor, ram, etc. Even better would be knowing more details such as peripherals. Ideally if there were a way to push service packs, and hotfixes (and other software?) to the machines, that would be great. What are some options for this?

• Limiting bandwidth on internal interface on Linux gateway

  - by Jack Scott

  I am responsible for a Linux-based (it runs Debian) branch office router that takes a single high-speed Internet connection (eth2) and turns it into about 20 internal networks, each with a seperate subnet (192.168.1.0/24 to 192.168.20.0/24) and a seperate VLAN (eth0.101 to eth0.120). I am trying to restrict bandwidth on one of the internal subnets that is consistently chewing up more bandwidth than it should. What is the best way to do this? My first try at this was with wondershaper, which I heard about on SuperUser here. Unfortunately, this is useful for exactly the opposite situation that I have... it's useful on the client side, not on the Internet side. My second attempt was using the script found at http://www.topwebhosts.org/tools/traffic-control.php, which I modified so the active part is: tc qdisc add dev eth0.113 root handle 13: htb default 100 tc class add dev eth0.113 parent 13: classid 13:1 htb rate 3mbps tc class add dev eth0.113 parent 13: classid 13:2 htb rate 3mbps tc filter add dev eth0.113 protocol ip parent 13:0 prio 1 u32 match ip dst 192.168.13.0/24 flowid 13:1 tc filter add dev eth0.113 protocol ip parent 13:0 prio 1 u32 match ip src 192.168.13.0/24 flowid 13:2 What I want this to do is restrict the bandwidth on VLAN 113 (subnet 192.168.13.0/24) to 3mbit up and 3mbit down. Unfortunately, it seems to have no effect at all! I'm very inexperienced with the tc command, so any help getting this working would be appreciated.

• ClearOS - how to avoid getting stuck at a fsck message at boot?

  - by Scott Szretter

  I have had this happen a couple times - I have a ClearOS Enterprise 5.2 box, and due to a power outage or similar, it ends up showing an error at boot and saying that fsck needs to be run (I think it said with (or without?) the -a parameter). The problem is, I need this box to be headless, at a remote location (miles away)! SO, I need to come up with a solution on how to either have it automatically repair itself, without someone to be present with a monitor and keyboard. Another possibility is to simply avoid the issue all together - maybe there is something that can be changed so it's very unlikely to happen (I am unable to avoid the power outage of course - at least not practically). Finally, maybe it can be boot off a read only media (cd) or file system or similar? At least the base OS, so that it would always at least boot with enough configuration that might allow remote access, or basic connectivity?
