• Can't detect wireless networks, running ubuntu 9.10 on eeepc 1000he

  - by David Brown

  Hi, I am running Ubuntu 9.10 on an ASUS eeepc 1000HE, and my wireless card, RaLink RT 2860, is failing to recognize any wireless networks. It was working fine this morning, until I accidentally hit Fn F2, disabling the wireless card. I hit Fn F2 again to reenable it, but it no longer will detect any wireless networks (and other computers in the household do recognize them). Any help at all will be greatly appreciated! I googled quite a bit and talked to a human about this but could not fix it. We tried dhclient ra0, which returned There is already a pid file /var/run/dhclient.pid with pid 2438 killed old client process, removed PID file Internet Systems Consortium DHCP Client V3.1.2 Copyright 2004-2008 Internet Systems Consortium.

• Route from Cisco ASA over site to site VPN

  - by Wookie321

  I want to be able to push f/w logging traffic to a server at a remote site. This server is accepting syslog traffic on port 514. In the ASA I've configured it to use this server as a syslog server. The Cisco f/w's inside interface address is 10.0.0.1 and I want to route over the link to an address of 192.168.1.1. The vpn is up and working between sites, and local clients at each site can access resources etc. How would I go about setting up the route from the f/w to this remote server only?

• Slapd service won't start, unable to open pid file

  - by Foezjie

  I'm trying to set up a test LDAP-server for some developers but I'm running into some trouble. service slapd start errors so I run /usr/sbin/slapd -d 1 and this gives me the following error at the end: unable to open pid file "/var/run/ldap/slapd.pid": 13 (Permission denied) slapd destroy: freeing system resources. slapd stopped. The rights for /var/run/ldap are as follows: root@pec:/var/run/ldap# ls -ld drwxr-xr-x 2 openldap openldap 60 2012-07-04 20:45 So I don't get why there is still a permission denied.

• Search files for text matching format of a Unix directory

  - by BrandonKowalski

  I am attempting to search through all the files in a directory for text matching the pattern of any arbitrary directory. The output of this I hope to use to make a list of all directories referenced in the files (this part I think I can figure out on my own). I have looked at various regex resources and made my own expression that seems to work in the browser based tool but not with grep in the command line. /\w+[(/\w+)]+ My understanding so far is the above expression will look for the beginning / of a directory then look for an indeterminate number of characters before looking for a repeating block of the same thing. Any guidance would be greatly appreciated.

• Windows 2003 Cluster: Failover Delay

  - by Ramon Marco Navarro

  I am testing the failover policies of our test failover cluster system. When I shutdown the node who is currently controlling the cluster (NODE1), it takes about 2 mins and 40 seconds before the next node on the preferred list (NODE2) takes control of the cluster. I tried changing the looksAlive and isAlive interval to 5000ms to all resources, but that didn't help. Looking at the Event Viewer of the remaining nodes, it shows that it was almost instantly detected that NODE1 was down. But it took another ~2:40 minutes for it to be removed from the live cluster list and for NODE2 to take over. Is there anyway of changing or shortening this "failover delay"? This is the setup of the cluster: (1) One ClusterDC connected to the public network (3) Three nodes running Win2003 with a quorum type of MNS Private network is connected to network hub ________________ _________________ (ClusterDC)=------=| |=------=(Node1)=------=| | |Public Network|=------=(Node2)=------=|Private Network| | (Switch) |=------=(Node3)=------=| (Hub) | ---------------- -----------------

• Microsoft Word RTF formatting breaks after pasting in HTML and saving

  - by meder

  I have developed an HTML e-campaign which uses tables and all the ugly stuff required for HTML emails. I'm pasting this via Open File ( I paste the URL ) and it retrieves the resources ( images ) and pastes the layout in MS Word. When I go and save this as an RTF, close Word and reopen the RTF, the images are broken. Anyone have a clue as to how to work around this issue? I can confirm 100% that the image resource is VALID, it's through http and NOT https. I've tried various advanced options relating to tables/formatting and all to no avail.

• Logging Bounced messages to a Database (Postfix with virtual domains/users)

  - by Gurunandan

  We have a postfix installation with a couple of virtual domains each with virtual users. These domains and users are mapped using a mysql database. I have been until now tracking bounces by parsing the postfix log file. I suspect there must be better and more efficient ways of doing this. I thought of three but I am not sure what is best: Write a Postfix content filter that logs the bounce and throws away the mail Use procmail - but I am not sure how procmail would work with virtual users who have no $HOME defined Write a script that POPs mail from mailboxes; parses and logs them and deletes the bounced email I would appreciate advise on which would be best from a maintenance point of view and efficient from conserving server resources point of view. Thanks

• Http 400 'Bad Request' and win32status 1450 when larger messages are sended to a WCF service

  - by Tim Mahy

  Hi all, we sometimes receive Http 400 bad request resultcodes when posting a large file (10mb) to a WCF service hosted in IIS 6. We can reproduce this using SOAP UI and it seems that it is unpredictable when this happens. In our WCF log the call is not received, so we believe that the request does not reach the ASP.NET nor WCF runtime. This happens on multiple websites on the same machine each having their own application pool. All IIS settings are default, only in ASP.NET and WCF we allow bigger readerQuota's etc.... The win32status that is logged in the IIS log is 1450 which we think means "error no system resources". So now the question: a) how can we solve this b) (when a is not applicable :) ) which performance counters or logs are usefull to learn more about this problem? greetings, Tim

• Locking down a box on the web

  - by glowcoder

  I'm a Java developer who is looking to put a game on the web. I'm not much of a web or server guy, though, and frankly I seem a little lost at where I should start with putting something on the web. My application works fine on my machine, and I'm sure I can make it work fine on any box I put it on. But the security of that box is pretty important. If I sign up for a standard hosting package (let's say from GoDaddy or something) can I simply tell them "make port 12345 open for communication" and let them handle the rest of the security details? If I can't, what are the things I'm going to need to know to prevent my game server from getting hacked to shreds? (Links to solid resources fine by me!) Thanks!

• Choosing between a dedicated and virtual dedicated server for my startup

  - by MarathonStudios

  I'm about to launch a startup site I've been working on for some time, and I'm just now looking over hosting plans. The site's main feature is fairly processor-heavy (a lot of text processing), so I probably need something other then shared hosting to ensure I don't get shut down for overusing resources. I would like to spend as little as possible on hosting until the site starts generating income, so under-$60/mo is my goal. One caveat is that I need a Windows box for this particular site, so it's harder to get a good deal. For that price, I can either get a bottom-tier dedicated (2gigs ram, pentium 4) or a middle-tier VPS (3gb RAM, a bit more traffic and HD) for a few bucks more per month. I had a bad experience with a low-end VPS a few months ago, so making sure that whatever I get can handle the basic traffic of a website as well as giving me what I need (extra processing power) is essential. Do you have any suggestions as to which way to go, or a certain hosting company you've worked with that you can recommend?

• trouble backing up large mysql database

  - by Patrick

  I have a wordpress MU database with something like 10,000+ tables for various user's blogs. I need to upgrade wordpress MU to newest version, but want to backup the DB before hand. PHPMyAdmin fails to even load the page when i click export. Ive tried going into the server (windows) and using dos command line: mysqldump -u USERNAME -p PASSWORD> BACKUP.sql but it hangs for a minute and gives me the error: error 23: out of resources when opinging file '.\USERNAME\wp_1037_links.MYD' (Errorcode: 24) when using LOCK Tables What am i doing wrong, or should i be doing? Is PHPMyAdmin right for something this size? Is there a better way of doing this than the two methods i tried? **Note that this is not my site, so any suggestions as to the setup of the DB ill have to run by the owner. Im just here for WP related crap, this is kind of out of scope for what i was brought on to do.

• How to configure CruiseControl.Net for Windows Authentication?

  - by balu

  I am using CruiseControl.Net for continuous integration which is now accessing the dashboard through login plugin, which in turn is authenticating and authorizing after verifying it with a set of users saved as XML file in the CruiseControl.Net server. Now, i need to bring in Windows Authentication to the system whereby which CruiseControl.Net server webdashboard when accessed from a client machine(local machine associated with a common server), would be authenticated and be authorized to access the CruiseControl.Net features based on the authority of the logged in users. Kindly guide me to go ahead with this, appreciate all kinds of resources that would be helpful for achieving this. Thanks.

• What happens to modern-ui apps when they aren't in the foreground?

  - by Mark Allen

  If I start a modern-ui app and then switch to a different app or a normal program running on the desktop, what happens to the first app? I've heard something about the first app being suspended, but realized that I don't really know that for certain. I mean, could you write a SETI@Home (BOINC) app if you wanted to, or will apps that aren't in the foreground always be suspended? Can you change that? I could see changing that based on available resources, running from AC vs. battery, etc. This morning I heard about an iPad being recovered thanks to the "Find my iPad" app, and was wondering whether you could write such a thing as a modern-ui app and have it work without being the running foreground app. (I'm aware that you'd just write a Windows service or similar, that's not what I'm asking about.)

• How can I determine which named property (or properties) are filling my exchange 2007 information st

  - by Mikey B

  Hi Guys, I'm experiencing the following error on an Exchange 2007 server: Event ID: 9667 Type: Error Category: General Source: msgidNamedPropsQuotaError Description: Failed to create a new named property for database "" because the number of named properties reached the quota limit (). User attempting to create the named property: . Named property GUID: . Named property name/id: . I understand that this can occur if the exchange information store is filling up with named properties... but I don't know how to determine which specific named property is at fault here. Is there a way to examine the DB for this type of info to see if there's a specific recurring named property that is consuming resources? -M

• Terminal OS X Error when using Python

  - by Stephen

  Hey, I'm trying to learn how to program so I've installed the latest version of Python and I've been following the Byte of Python tutorial. I'm using Textwrangler I've only gotten as far as the simple "Hello World" intro and I'm already having a problem. I type out the code (just without the ""): "#!/usr/bin/python" "#Filename: helloworld.py" "print('Hello World')" and save it to my desktop as helloworld.py. I then go into terminal and type "python3 helloworld.py" and I get the following error message: /Library/Frameworks/Python.framework/Versions/3.1/Resources/Python.app/Contents/MacOS/Python: can't open file 'helloworld.py': [Errno 2] No such file or directory I was hoping someone could tell me what I'm doing wrong. If I choose to run the script from Textwrangler it operates just fine however I'm not able to access it from the Terminal. Thanks so much!

• Autoloading Development or Production configs (best practices)

  - by Xeoncross

  When programming sites you usually have one set of config files for the development environment and another set for the production server (or one file with both settings). I am assuming all projects should be handled by version control like git or svn. Manual file transfers (like FTP) is wrong on so many levels. How you enable/disable the correct settings (so that your system knows which ones to use) is a problem for me. Each system I work on just kind of jimmy-rigs a solution. Below are the 3 methods I know of and I am hoping that someone can submit a more elegant solutions. 1) File Based The system loads a folder structure based on the URL requested. /site.com /site.fakeTLD /lib index.php For example, if the url is http://site.com then the system loads the production config files located in the site.com folder. However, if I'm working on the site locally I visit http://site.fakeTLD to work on the local copy of the site. To setup this I edit my hosts file and add site.fakeTLD to point to my own computer (127.0.0.1/localhost) and then create a vhost in apache. So now I can work on the codebase locally and then push to the server without any trouble. The problem is that this is susceptible to a "host" injection attack. So someone loading site.com could set the host to site.fakeTLD and then the system would load my development config files instead of production. 2) Config Based The config files contain on section for development - and one for production. The problem is that each time you go to push your changes to the repo you have to edit the file to specify which set of config options should be used. $use = 'production'; //'development'; This leaves the repo open to human error should one of the developers forget to enable the right setting. 3) File System Check Based All the development machines have an extra empty file called "development.txt" or something. Each time the system loads it checks for this file - if found then it knows it is in development mode - if missing then it knows it is in production mode. Since the file is NEVER ADDED to the repo then it will never be pushed (and checked out) on the production machine. However, this just doesn't feel right and causes a slight slow down since all filesystem checks are slow.

• Idle VMware Guests Resource Consumption

  - by Ravenor

  I want to setup a number of guests with multiple CPUs (4) and at least 4Gb ram running Ubuntu Linux. These machines will mostly be idle, but from time to time their workload will require all their resources, especially the CPU. The hosts are ESXi 5.x. The question is, am I right in thinking that the resource consumption of the machines when idle will be negligible? We know this true of disk and the CPU. The only concern left therefore is memory. Since ESX over-commits memory it makes sense that unused memory of any guest is paged out. If my thinking correct?

• Doubts about Cloud Infrastructure

  - by Pravin

  Maybe a little more of the same questions that others have asked but wanted to clarify my doubt, for some years run my hosting company (reseller of esds) and I've done well so far, but I am determined to bring quality and server technology to offer another level. So far I have understood that there is a difference between cloud and cluster servers because the cluster function as load balancers that distribute in different servers roles and use the servers less overloaded in the cloud is the union of multiple servers and then the same is vitualized unlike the cluster that is allowed to use the resources of the CPU and RAM servers in the virtualized environment. My approach is to use 3 dedicated servers to create a cloud server, My doubts: Does this type of cloud servers are only reserved for big companies? (Either because the union of the servers is done by hardware or software with high price) What characteristics should these servers meet? Possibly through software which should be used? Available? Thanks for your time, Cheers!

• What causes winsock 10055 errors? How should I troubleshoot?

  - by Tom Kerr

  I'm investigating some issues with winsock 10055 errors on a chain of custom applications (some of which we control, some not) and was hoping to get some advice on techniques to troubleshoot the problem. No buffer space available. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. From research, non-paged pool and ports seem to be the only resources which can cause this error. Is there another resource which might cause 10055 errors? Currently, we have perfmon counters setup on the applications and non-paged pool usage looks low in most circumstances. Open TCP connections looks low and I am unaware of another way to monitor ports. Since it only happens in production, we are unable to use more invasive counters. Is there some other tool or procedure you would recommend to diagnose which application is causing the issue?

• DNS updating issue

  - by Will

  Hey guys, I'm new to serverfault so please excuse me if I sound a tad nub. I work in an environment that is kinda peace mealed together, and I honestly don't know how it works. I'm new to the IT field and am still in school. When I replace a PC I rename the old one to mo-o-pcname and give the new one the proper name of mo-pcname (mo is a location thing we use so it really doesn't apply to the problem.) The new PC will function on the network; it will have the ability to access network resources (printers, file shares, etc) and it will have the ability to get out to the internet. However I can no longer ping the machine. It would appear as if the DNS (A) record is not getting updated or something. Like I said I'm kinda new to the field and just trying to work through this problem. Thanks for your help.

• Handling inconcistent resource availability in Project 2007

  - by Lachlan McDonald

  Afternoon all, I have four resources; a project manager, and three developers. The project manager can work anywhere from 9 to 5pm each day, but only for a total of 10 hours per week. It doesn't matter when he works, as long as he isn't over-allocated 10 hours per week. The developers on the other hand can only work up to 2 hours per day, for a total of 10 hours per week. If they work more than 2 hours in a day, they are over-allocated. How do I best configure Project to handle this kind of scheduling requirement?

• User cannot book a room resource in Exchange 2010

  - by bakesale

  Im having a problem with a specific user not being able to book a room resource. No error message is generated at all. The user attempts to add the room as a meeting resource and it simply doesnt register with the resources calendar. I have tested the resource with other accounts and other rooms for this user but it is only this room that is having issues for this user. This Exchange server was migrated from 2007 to 2010. All rooms except for the problem room were created back on Exchange 2007. This new room was created with Exchange 2010. Maybe this clue has something to do with the problem? This is a paste of the mailboxes folder permissions [PS] C:\Windows\system32Get-MailboxFolderPermission -identity room125:\calendar RunspaceId : 448ab44a-4c2a-4403-b46c-fce1106c0823 FolderName : Calendar User : Default AccessRights : {Author} Identity : Default IsValid : True RunspaceId : 448ab44a-4c2a-4403-b46c-fce1106c0823 FolderName : Calendar User : Anonymous AccessRights : {None} Identity : Anonymous IsValid : True

• World Wide Publishing Service very slow to restart on IIS? Why?

  - by StacMan

  Every now and then, we look to restart our IIS server by restarting the "WWW Publishing Service". On most systems this would usually only take a minute or two, but this can often take up to 10 minutes to stop the server and restart. Does anyone know any way to work out what is taking so much time to stop the service? After reading up around the net I've learned this may be due to locked resources used by users and/or lower-level IIS cached items being recycled. But I cant seem to work out where I can validate if this is true on not. Also if anyone knows how to fix or speed this up, that would be excellent. We have a large codebase which contains over 280 aspx pages across the site. Our main domain contains about 100 aspx pages whilst the subdomains contain 15 or 20 each. Some specs: Code is written in C#; runs on .Net framework 2.0 Server Windows Web Server 2008 IIS7; DB running SQL Server 2008 Standard

• Stop SQL Server services from conveniently

  - by MedicineMan

  I have a general use laptop. I use it for games, development, and web surfing. I've just installed SQL Server 2008 with Analysis, Reporting, and Error reporting, as well as any of the other options on the installer. I also have a default instance of SQL server as well as a named instance. When I'm not doing development, I'd like to shut down these services conveniently. I'm thinking that a batch file would be good. What are the commands to shut these services down and release the associated memory and resources? It appears that: net stop MSSQLSERVER seems to stop the MSSQLSERVER instance. What about the other services?

• Logitech Optical Mouse Frozen In Middle of Windows XP Pro Screen

  - by Code Sherpa

  I have a Logitech Optical Mouse/Keyboard. I have been using them just fine with the system drivers for almost a year now. I recently updated my Kaspersky software and rebooted. Now the mouse is frozen in the middle of my screen. I am not able to login to the Windows XP Pro box that has the frozen mouse (because i can't work the mouse) but am able to remote desktop to this computer. Things I know / have tried: When I boot on the problem computer, I am able to use the keyboard, but not the mouse. I have installed the latest version of Logitech's SetPoint (with the updated drivers) on the problem computer (via remote desktop) and that didn't seem to matter. I bought new batteries for the mouse and that didn't matter. I have tried the mouse/keyboard on another computer and the mouse works just fine there. My suspicion is that the Kaspersky install has overwritten a driver of some sort. Things I have not done (and would appreciate detailed steps if you feel this is the way to go): 1) Uninstalled all the mouse drivers on the machine and reboot. Then, reinstall. Note: When I get to the Device Manager I don't see an option for Human Interface Devices (where the mouse device is). Here are my options: Computer, Disk Drives, DVD/CD-Rom drives, Floppy controllers, IDE ATA/ATAPI, Imaging devices, Network Adapters, Other devices, Ports, Processors, Sound, video, and gaming, System devices, USB controllers. Also, I should point out that Video Controller is the only thing under Other devices and it has a yellow exclamation mark. The same is true for all the items under Universal Serial Bus controllers. I think this means I have to update my BIOS but, since my mouse was working just fine without doing that, I don't think that is my problem. So, how do I get to my Mouse Device? 2) Update my BIOS. Note: As pointed out above, I don't think this matters as my mouse was working just fine under my computer's current BIOS version. Thanks for your help.
