  • Get drop down selection from GridView on button press

    - by Chris Stewart
    I have an ASP.NET GridView that has four columns. The first three are typical BoundField elements bound to a DataTable. The forth is a TemplateField element that I create a DropDownList in on the OnRowCreated event for the GridView. What I'm attempting to do is walk down the data source for the GridView when a button is pressed. I really just need to get the values for columns one and four of each row. The first three columns have data as expected but the forth is displaying as empty. Is this because it wasn't a part of the DataTable originally? Is there any way to get the value for each drop down as I've described it, or will I need to rework this so each drop down list is a part of the DataTable?

  • lighttpd: Backend is overloaded + fcgi-server re-enabled + all handlers are down

    - by AbuZubair
    We have a standard lighttpd deployment with PHP-CGI and our error logs are flooding with the following. This is causing a huge problem because we keep returning 500's to our clients: 2012-10-14 14:28:38: (mod_fastcgi.c.3001) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 36 2012-10-14 14:28:38: (mod_fastcgi.c.2764) fcgi-server re-enabled: 0 /tmp/php-7735.socket 2012-10-14 14:28:39: (mod_fastcgi.c.2764) fcgi-server re-enabled: 0 /tmp/php-7735.socket 2012-10-14 14:28:40: (mod_fastcgi.c.3001) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 37 2012-10-14 14:28:40: (mod_fastcgi.c.2764) fcgi-server re-enabled: 0 /tmp/php-7735.socket 2012-10-14 14:28:41: (mod_fastcgi.c.3001) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 57 2012-10-14 14:28:41: (mod_fastcgi.c.3001) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 57 2012-10-14 14:28:42: (mod_fastcgi.c.3597) all handlers for /index.php? on .php are down. Does anyone have any clue as to what is going on? We restarted all php and lighttpd related processes and that didn't fix the problem. We ended up rebooting the whole box and now its gone away, although we fear it may come back later.... In general our deployment has been doing fine for a long time and this is the first time this has happened.

  • Making the iPhone work with stripped down Windows XP

    - by Gabriel
    Hi, this is my first time posting here and I have a really specific question. I have an ASUS eee 901 running Windows XP Home. I had everything working well, but then I decided to improve performance by moving Windows to the smaller but faster internal SSD. I used Nlite to strip down Windows, following the instructions here: http://wiki.eeeuser.com/howto:nlitexp I now have a very lightweight installation of XP home with SP3 and all the current updates. Almost everything is working really well. I have installed iTunes and I CAN sync with no problems. However, each time I plug in my iPhone 3GS (latest firmware), Windows tries and fails to install drivers. The Found New Hardware Wizard launches, but nothing I do will make it complete successfully, with the result that the iphone does not show up in Windows as removable storage, or as a camera. When I launch the Camera and Scanner Wizard, it shows only my webcam, not the iphone. I have verified that I have the following files in place: Windows\System32\ptpusb.dll (regsvr32 successful) Windows\System32\ptpusd.dll (entry point not found, can not be registered) Windows\System32\usbaaplrc.dll (entry point not found, can not be registered) Windows\System32\drivers\usbaapl.sys Windows\System32\drivers\usbscan.sys Windows\System32\drivers\usbstor.sys Does anyone know if some other file is required or if there's some other element preventing this from working? Edit (From posted answer) I did select Cameras & Camcorders, and my webcam is working fine for video & still capture.

  • Good PC-based video conference control tools?

    - by Jeremy Wadhams
    I'm looking to improve the user experience in our video conference rooms, by simplifying the things users do all the time (setting up a call, muting and unmuting, panning and zooming between a few room-appropriate presets) and totally taking away the functions that we don't use or that are more likely to ruin the experience (changing the brightness of the TV, using the VNC presenter mode). The rooms each have Tandberg Edge or MXP video units, I'm not looking at PC-based solutions like Skype or iChat. The classic way to do this would be to plunk down huge money for an AMX or Crestron panel. This does have some advantages, and I am considering that approach, but in my initial investigation, that looks expensive, inflexible, and proprietary. On the other hand, the Tandberg video units I'm looking to control are very thorough XML API (PDF), so some of the integration magic that Crestron and AMX consider to be a value add, I could reproduce at mashup speeds. Anyone aware of an Open Source or Commercial product that takes advantage of the readily available web APIs, some simple touch screen PCs, and builds a product that is more like skinning an AJAX web app, and ideally more cost effective than the proprietary panels?

  • apache with php fastcgi keeps going down

    - by Josh Nankin
    I have an apache2 server configured with MPM worker and php fast cgi. Lately the apache logs have been telling me that MaxClients is being reached frequently, even though it's already pretty high. My server is now constantly going down, and I see a bunch of lines like this in the log: [Sun Mar 06 04:25:40 2011] [error] [client 50.16.83.115] FastCGI: comm with (dynamic) server "/var/local/fcgi/php-cgi-wrapper.fcgi" aborted: (first read) idle timeout (20 sec) [Sun Mar 06 04:25:40 2011] [error] [client 50.16.83.115] FastCGI: incomplete headers (0 bytes) received from server "/var/local/fcgi/php-cgi-wrapper.fcgi" I can see that my php-cgi processes are pretty large (about 70mb on average). Here's my apache configuration for MPM worker: KeepAlive ON KeepAliveTimeout 2 <IfModule mpm_worker_module> StartServers 5 MinSpareThreads 10 MaxSpareThreads 10 ThreadLimit 64 ThreadsPerChild 10 MaxClients 20 MaxRequestsPerChild 2000 </IfModule> Heres my fastcgi apache configuration: <IfModule mod_fastcgi.c> # One shared PHP-managed fastcgi for all sites Alias /fcgi /var/local/fcgi # IMPORTANT: without this we get more than one instance # of our wrapper, which itself spawns 20 PHP processes, so # that would be Bad (tm) FastCgiConfig -idle-timeout 20 -maxClassProcesses 1 <Directory /var/local/fcgi> # Use the + so we don't clobber other options that # may be needed.

  • Why are SMART error rates going down?

    - by Jeff Shattock
    I have a hard drive that's part of a Linux software raid5 array. SMART has reported that its multi_zone_error_rate was 0, then 1, then 3. So I figured I better start backing up more frequently and prepare to replace the drive. Now, today, the multi_zone_error_rate of that very same drive is back down to 1. It seems that 2 errors unhappened while I wasn't looking. I've also seen simliar behaviour by inspecting the syslog on the server. Jun 7 21:01:17 FS1 smartd[25593]: Device: /dev/sdc, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 7 21:01:17 FS1 smartd[25593]: Device: /dev/sde, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 7 21:01:18 FS1 smartd[25593]: Device: /dev/sdg, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 8 02:31:18 FS1 smartd[25593]: Device: /dev/sdg, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 Jun 8 03:01:17 FS1 smartd[25593]: Device: /dev/sdc, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 Jun 8 03:01:17 FS1 smartd[25593]: Device: /dev/sde, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 These are raw values, not the human-useful values that smartctl -a produces, but the behaviour is similar: error rates changing, then undoing the change. None of these are the drive that had the multi_zone weirdness. I haven't seen any problems from the RAID; its most recent scrub ( < 24 hours ago) came back totally clean. The only thing I can think of is that the SMART reporting circuitry on the drive isn't working properly all the time. The cables are in tight on the drive and board. What's going on here?

  • What should I set so that VMware tools is running after a guest reboots or comes back from sleep?

    - by Thierry Lam
    On my Ubuntu 10.04 Server guest VM running from VMware fusion, the VMware tools doesn't seem to be running after a reboot or my computer comes back from stand-by or sleep(when I close my MacBook lid): $ /etc/init.d/vmware-tools status vmware-guestd is not running I did try running it as a service but the tools would still not run after coming back from stand by: sudo service vmware-tools start Any ideas what I should do to make the tools run all the time? My Ubuntu Server can only be accessed from the CLI, I won't be able to try any GUI solution.

  • Tracking down the cause of a web service fault running in IIS

    - by BG100
    I have built a web service in Visual Studio 2008, and deployed it on IIS 7 running on Windows Server 2008 R2. It has been extensively tested, handles all errors gracefully and logs any uncaught errors to a file using log4net. The system normally runs perfectly, but occasionally (2 or 3 times a day) a fault occurs and screws up the application which needs an iisreset to get it working again. When the fault occurs I get some random errors that are caught by my catch-all error log, such as: Value cannot be null. Could not convert from type 'System.Boolean' to type 'System.DateTime'. Sequence contains no elements These errors are raised on every request until I manually do an iisreset, but there is no sight of them when the system is running normally. The web service is a stateless request-response application. Nothing is stored in the session. It could be load related, but I doubt it as there are only around 30 or 40 requests per minute. This is proving very tricky to track down. I can't work out what is putting IIS into this bad state, and why it needs an iisreset to get it working again. Nothing is reported in the event log. Can anyone suggest how to enable more extensive logging that might catch this fault? Also, does anyone know what might be causing the problem?

  • Netbook (Samsung N220) on Ubuntu 10.04 slows down WiFi for other computers

    - by Joachim
    I encountered a really odd problem with my new netbook. I am running Ubuntu 10.04 on a Samsung N220 Mito. So far everything worked fine. Now I tried the machine for the first time in our work group where we have a wifi (with internet access) for all laptops. The wifi is controlled by a computer running Suse 9.3 which provides a DHCP server and imposes a firewall. At the moment there is only a macbook in the wifi, where no problems with the internet or wifi connection are encountered. Now coming to my actual problem: In addition to the macbook i connect the Samsung N220 to the Wifi. Problem: My download speed is for some reason limited to 70KB/s max. This is neither a limitation of the server/website i browse on, nor a configuration of the netbook: at home i have 500KB/s download speeds. Furthermore, it is not a default limitation for "untrusted" or "new machines" in the wifi, as for instance other new laptops get full speed internet with our wifi. Problem: Once the Samsung N220 is generating traffic in the wifi, the wifi is slowed down dramatically for all other machines: I run a ping to the router from the macbook. The ping times with the N220 ideling are 2-6ms. When I start downloading or browsing in the web with the N220 the ping speed drops to 800ms. Vice versa, when the macbook is generating the traffic the ping of the N220 to the rooter stays constant at around 2-6ms. So clearly, it is some problem originating from my netbook or maybe its treatment in the wifi. Thanks for any help

  • iptables management tools for large scale environment

    - by womble
    The environment I'm operating in is a large-scale web hosting operation (several hundred servers under management, almost-all-public addressing, etc -- so anything that talks about managing ADSL links is unlikely to work well), and we're looking for something that will be comfortable managing both the core ruleset (around 12,000 entries in iptables at current count) plus the host-based rulesets we manage for customers. Our core router ruleset changes a few times a day, and the host-based rulesets would change maybe 50 times a month (across all the servers, so maybe one change per five servers per month). We're currently using filtergen (which is balls in general, and super-balls at our scale of operation), and I've used shorewall in the past at other jobs (which would be preferable to filtergen, but I figure there's got to be something out there that's better than that). The "musts" we've come up with for any replacement system are: Must generate a ruleset fairly quickly (a filtergen run on our ruleset takes 15-20 minutes; this is just insane) -- this is related to the next point: Must generate an iptables-restore style file and load that in one hit, not call iptables for every rule insert Must not take down the firewall for an extended period while the ruleset reloads (again, this is a consequence of the above point) Must support IPv6 (we aren't deploying anything new that isn't IPv6 compatible) Must be DFSG-free Must use plain-text configuration files (as we run everything through revision control, and using standard Unix text-manipulation tools are our SOP) Must support both RedHat and Debian (packaged preferred, but at the very least mustn't be overtly hostile to either distro's standards) Must support the ability to run arbitrary iptables commands to support features that aren't part of the system's "native language" Anything that doesn't meet all these criteria will not be considered. The following are our "nice to haves": Should support config file "fragments" (that is, you can drop a pile of files in a directory and say to the firewall "include everything in this directory in the ruleset"; we use configuration management extensively and would like to use this feature to provide service-specific rules automatically) Should support raw tables Should allow you to specify particular ICMP in both incoming packets and REJECT rules Should gracefully support hostnames that resolve to more than one IP address (we've been caught by this one a few times with filtergen; it's a rather royal pain in the butt) The more optional/weird iptables features that the tool supports (either natively or via existing or easily-writable plugins) the better. We use strange features of iptables now and then, and the more of those that "just work", the better for everyone.

  • What tool to use to check newly built PC before installing Windows?

    - by Borek
    There is a similar question: http://superuser.com/questions/31786/what-tools-to-test-the-reliability-and-stability-of-a-newly-built-pc but I'm interested in some tool / bootable CD that would check the PC (CPU, RAM, GPU) before I install Windows. Reason: I'm just installing Win7 64b on a machine with Core i7 and SSD and it's suspiciously slow (after 15 minutes, it's just began expanding installation files) so I'm seeking tools that would help troubleshoot it.

  • Nagios check_host_alive and check_ping not showing host as down

    - by Kyle
    I am using the check_host_alive command to send 5 packets every minute to all my routers at remote locations. I noticed today I received a notification from The AT&T Global Client Support Center that a router was down (which can take 5-30 minutes to send these notices out) and never received a notice from Nagios. I went onto Nagios and it is was showing the host as alive with a latency of 0ms. This tells me it is seeing the automated response from my router in the data center that, "TTL expired in transit" as a reply from the remote router. Is there anyway for me to tell nagios to check where the reply is comming from? I feel like other people have to of had this issue... I tested it with the check_ping command and it produced the same results. I have the command defined has %hostname% and the proper IP in the host definition, and it works fine for telling me the latency is high. Any ideas are welcome, I have already exercised my Google skills with no results. EDIT: root@IM-UBTU:/# /usr/local/nagios/libexec/check_ping -H 192.168.250.1 -w 100.0,10% -c 200.0,20% -vvv CMD: /bin/ping -n -U -w 10 -c 5 192.168.250.1 Output: PING 192.168.250.1 (192.168.250.1) 56(84) bytes of data.

  • Fill down in Excel, but based on multiple values

    - by Jenn D.
    I have spreadsheets (not created by me) that have blank entries in one column where they should really have data. I want to take every empty cell and fill it with the nearest value above it. I'm looking for as little manual intervention as possible, because I'll have to do it repeatedly. I thought some previous version of Excel, or maybe another spreadsheet from the distant past, would do this by default -- that is, if you selected the column with foo and bar, and chose the equivalent of "fill down", you would get what's in the WANT column. What I actually get in Excel is the GET column. HAVE: WANT: GET: foo 1 foo 1 foo 1 2 foo 2 foo 2 bar 1 bar 1 foo 1 2 bar 2 foo 2 3 bar 3 foo 3 I'm worried that this might need a macro to be done properly. I used to be a whiz with Excel macros, and then suddenly they were all in VB. My fallback position will be to dump the whole thing to CSV and write a Python script, but if there's any way to do it in Excel that would be much preferable. Even if it involves a couple of different manual steps, that's fine; just not one step per group of lines. That is, a process of "copy the column, do X to it, cut and paste it back" would work, but "do X for each occurrence of foo or bar" won't. The files are too big for that. Any thoughts are appreciated!

  • Jailkit not locking down SFTP, working for SSH

    - by doublesharp
    I installed jailkit on my CentOS 5.8 server, and configured it according to the online guides that I found. These are the commands that were executed as root: mkdir /var/jail jk_init -j /var/jail extshellplusnet jk_init -j /var/jail sftp adduser testuser; passwd testuser jk_jailuser -j /var/jail testuser I then edited /var/jail/etc/passwd to change the login shell for testuser to be /bin/bash to give them access to a full bash shell via SSH. Next I edited /var/jail/etc/jailkit/jk_lsh.ini to look like the following (not sure if this is correct) [testuser] paths= /usr/bin, /usr/lib/ executables= /usr/bin/scp, /usr/lib/openssh/sftp-server, /usr/bin/sftp The testuser is able to connect via SSH and is limited to only view the chroot jail directory, and is also able to log in via SFTP, however the entire file system is visible and can be traversed. SSH Output: > ssh testuser@server Password: Last login: Sat Oct 20 03:26:19 2012 from x.x.x.x bash-3.2$ pwd /home/testuser SFTP Output: > sftp testuser@server Password: Connected to server. sftp> pwd Remote working directory: /var/jail/home/testuser What can be done to lock down SFTP access to the jail? FWIW, I mostly used this as a guide: http://digitalpatch.blogspot.com.ar/2010/03/openssh-daemon-hardening-part-3-setup.html

  • Mysqld shutting down by itself

    - by AJ Naidas
    I'm running a Wordpress Blog that gets medium-high traffic. It is hosted in an Ubuntu Server 2GB Memory 2 Core Processor 40GB SSD Disk, 3TB Transfer. The problem is that MySQL shuts down by itself after an hour or two. I had to restart mysql each and every time this happens. I checked the logs and this is what I found: 140612 6:48:14 [Warning] Using unique option prefix myisam-recover instead of myisam-recover-options is deprecated and will be removed in a future release.

  • Active Directory server down, recovering without reinstalling

    - by whatever
    My Windows 2003 server suddenly ceased to function as a DC (this server is the only DC of the domain). All AD related services are down. The only way I can login to the AD is physically to the machine. Everytime I access an AD-related service (e.g. "AD users and computers") I get the below error: Naming information cannot be located because: The specified directory service attribute or value does not exist. Contact your system administrator to verify that your domain is properly configured and is currently online. I found the below system event which matches the time when the issue started, this re-occurs everytime I reboot the server. NTDS General | Global Catalog | Active Directory was unable to establish a connection with the global catalog. Additional Data Error value: 1355 The specified domain either does not exist or could not be contacted. Internal ID: 3200d33 I started the troubleshooting with DNS. Netdiag throws the below error although I think this is simply a consequence of not being able to access the Global Catalog. The procedure entry point DnsGetPrimaryDomainName_UTF8 could not be located in the dynamic link library DNSAPI.dll. Anyway DNS seems OK because I can ping the DC FQDN from the DC itself. I found the below solution which is supposed to help by doing some cleanup of the metadata: http://support.microsoft.com/kb/216498 If I follow procedure 1 here is what I get at step 9: no current site Domain - DC=<mydomain>,DC=<com> no current server no current naming context I can continue the procedure until step 14. I haven't tested step 15 as my understanding is that I will have to reinstall the whole AD again. Is there any way I can recover my AD from there without having to reinstall the whole thing? Update: Yes, the server was powered off/on because reboot would take forever (not because I thought power cycling the unit would fix it more than a reboot).

  • Network card shuts down when stressed

    - by user142485
    I have a network card that functions fine with light use, but quits functioning after heavy use. I replaced it with a brand new one and still have the same issue, also updated drivers. It is a wired D-Link card. The Internet seems fine for a small amount of web browsing but when I run a bandwidth test it starts out fast and slows quickly until the card completely quits; I have a constant ping of the gateway going while I run this and it starts timing out after a couple seconds into the speed test. The card will stay on and the data light on it still flashes some but I cannot ping the gateway or anything else until the computer is rebooted. When I boot into safe mode I can browse and run the speed test fine with no problems. I am guessing that this is probably some program that is loading in regular mode but not safe mode that is causing the issue? I have very limited software (turned off av and firewall) on the computer but I am thinking that I'll just have to start eliminating start-up programs and see if that helps. This is on Windows 7 if that makes any difference. Anyone had a similar issue or have any other suggestions/ideas for narrowing down this problem?

  • Why would my network slow down?

    - by monkthemighty
    The network at my work has about 40 computers on it and a quite a few printers. When there are a lot of people working the network will be slow. I can test the ping between my computer and the router and it will keep rising, sometimes to the point that it times out. The router we are using is running Ubuntu on a atom processor and it has 4gb of ram. When the network slows the process Ksoftirq will be using most if not all of the processing power. I have found that Ksoftirq is a process that handles irq requests. Also when the network slows down I have captured packets from the router and using tshark and looked at it using wireshark on my laptop. With the capture show a lot of packets with TCP Dup ACK and TCP Retransmissions. The destinations of the TCP Dup and TCP retransmissions are to most of the computers on the network but there are some that are far more than others. What could this problem be caused by?

  • Web Server slows down (ASP.NET)

    - by mfeingold
    below is a question I posted on stackoverflow . as suggested by Martin Clarke I also post it here. We have a really strange problem. One of the servers in the server farm becomes really slow. We see a number of timeouts in the logs and overall response time is not where it should be (and is on other servers in the farm). What is also strange is that it is not just the web app - Just logging into the server takes up to 1.5 min to show you the desktop. Once you are in, the system is as responsive as ever - unless you try to launch something, i.e. notepad - it takes another minute to launch and after launch it works fine. I checked a number of things - memory utilization is reasonable, CPU is below 15%, windows handles, event logs do not show anything. Recycling the aps.net process does not fix it - it still takes over a minute to log in. Rebooting the server helped, but now it started to slow down again. After a closer look we found out that Windows Temp directory is full of temp files - over 65k files. This is certainly something to take care of. But my question is could it be the root cause of the sluggishness, or there is still something else lurking in the shadows? Edit After more digging I am zeroing in on the issue related to the size of temp directories. This article: (see the original post this thing will not let me include a second link) describes something very similar. It still does not answer the question why the server is still slow even there is no activity.

  • Cannot open /dev/rfcomm1 : Host is down

    - by srj0408
    I am working on raspberry PI and on Bluetooth. I am using old raspberry pi kernel as the new one has got some bugs that were not resolved with respect to the bluez daemon. At present my kernel version is 3.6.11. I am using a USB bluetooth dongle and my sole purpose is to auto connect the bluetooth dongle when ever it is in range. For that i think i have to run a script in the backend on RPI that will keep on checking the existence of usb bluetooth dongle. I started from the very scratch. I installed bluez daemon using apt-get install bluetooth bluez utils blueman and then i used hciconfig which gives me that my bluetooth usb dongle is working fine. But when i did hcitool scan , it give me no device in range even though my Serial bluetooth Device was on. I wasn't able to find any device in vicinity. Also when i unplugged and plug the USB dongle again, i was able to scan the serial device , but when i repeat the process, i find the earlier condition of not finding any deice. I had find another useful link, but that need address of the bluetooth device that need to be connected. I want to automate this using hcitool scan, storing the output to the a file and then comparing it with already paired devices and their name. For that i need to figure out why hcitool scan is sometime working and sometime not. ? Can some one help me in figuring out why this is happening. Is there any problem on hardware side i.e Bluetooth dongle is buggy or i had some problem in bluez utils. Edit 1: While as of now, hcitool scan is giving me my remote device address but still i am getting the same issue of HOUST IS DOWN, '/dev/rfcomm1'. I am really not getting any idea of what to be done.

  • How do I calculate the week number given a date?

    - by GH
    If I have a date, how do I calculate the week number for that date within that year? For example, in 2008, January 1st to January 6th are in week 1 and January 7th to the 13th are in week 2, so if my date was January 10th 2008, my week number would be 2. An algorithm would be great to get me started and sample code would also help - I'm developing in C++ on Windows. Related: Getting week number off a date in MS SQL Server 2005?

  • View Source and Chrome Developer Tools showing different output

    - by patricksweeney
    I have a page located here. Viewing it in Chrome and Firefox show a really small h1 title, and also it changes color as if it is a link. The template that generates everything looks exactly how it should be. When diagnosing the issue, the relevant section of code looks like this when I go to view source: <div class="page-heading"> <h1>Title Here</h1> </div> However, when I go to view it in Chrome's Developer tools, it is throwing in extraneous malformed anchor tags, which is obviously causing the hovering behavior. This is what it looks like to the dev tools: <div class="page-heading"> <h1> <a style="font-family: arial; font-size: 9px" <="" a="">Title Here</a> </h1> </div> In addition, when viewing a local copy of the site, the output shown in the dev tools is the same as viewing the source and they both render correctly locally. Oddly enough, all version of IE render it correctly. The current version of both Chrome and Firefox both render it weirdly. Initially I thought it may be a user agent stylesheet problem, but if anything the CSS is fine, it's the HTML that is malformed.
