  • Cannot connect to remote mail server for sending emails in ASP.NET

    - by Dave
    I want to migrate a web application from a Windows Server 2003 to a Windows Server 2008 R2. All works fine except sending emails from the application. If I configure the application to use the smtp server on "localhost" it works, but changing it to the "real" host name (e.g. mail.example.org) no mail is sent. The error message says, that the remote server needs a secure connection or smtp authentication. But since it works when using "localhost" instead of the host name I doubt that this is the problem. Also it's unlikely a problem with the mail server, I also tried it with another one. So for me it seems like the firewall is blocking the outgoing connection to the mail server. I tried to open port 25, but it still did not work. Maybe I just did it the wrong way. Update: For clarifying my setup: I have a Windows Server 2008 R2 with hMailServer installed (set up for some of the hosted domains) For the website I'm talking about I need to use an external mail server (totally different hosting provider) Apparently I was a bit off the track. It seems like it works when using connecting to the local mail server either with the host name "localhost" or "mail.somedomain.com" (while somedomain.com is set up in my mail server). But when using the host name of the external mail server ("mail.externaldomain.com") it seems like it tries to connect to the local server again, although this domain is not set up in the mail server. Thanks to Evan Anderson for the tip to use telnet - why I have not thought of it myself?... :-) Note, the website www.externaldomain.com is hosted on my server but the DNS entries are maintained by the other hosting provider. "externaldomain.com" is the only entry which points to my server all other records (MX, subdomains) are pointing to the other server. So I think the question is now, how do i bring my server to connect to the external mailserver. Do I have to configure this in my mail server or is it a windows server thing?

  • grouping two sites under domain and sub domain

    - by Dave
    I have 2 websites a main website hosted at fasthosts and an e-commerce website hosted at Vidahost. I want to combine both websites under the same domain set. Main site would be www.mydomain.com Store site would be shop.mydomain.com I want to keep the directory path showing on the shop subdomain so what was previously www.mystore.com/product/hat would become shop.mydomain.com/product/hat How can I accomplish this, have already created the subdomain on fasthosts and setup web forwarding to the store but the directory paths do not show.

  • How to generate user-specific PDF with encrypted hidden watermark?

    - by Dave Jarvis
    Background Using LaTeX to write a book. When a user purchases the book, the PDF will be generated automatically. Problem The PDF should have a watermark that includes the person's name and contact information. Question What software meets the following criteria: Applies encrypted, undetectable watermarks to a PDF Open Source Platform independent (Linux, Windows) Fast (marks a 200 page PDF in under 1 second) Batch processing (exclusively command-line driven) Collusion-attack resistant Non-fragile (e.g., PDF - EPS - PDF still contains the watermark) Well documented (shows example usages) Ideas & Resources Some thoughts and findings: Natural language processing (NLP) watermarks. Apply steganography on a randomly selected image. http://openstego.sourceforge.net/cmdline.html The problem with NLP is that grammatical errors can be introduced. The problem with steganography is that the images are sourced from an image cache, and so recreating that cache with watermarked images will impart a delay when generating the PDF (I could just delete one image from the cache, but that's not an elegant solution). Thank you!

  • Citrix Access Gateway not redirecting to login URL

    - by Dave
    We have an older setup for XenApp - users log in through Citrix Secure Gateway running on a windows box. (We hope to start using a NetScaler soon.) Earlier today, connections to https://citrix.company.com/ starting throwing up a 503 error page, instead of redirecting to https://citrix.company.com/Citrix/XenApp/ If you go directly to the /Citrix/Xenapp/ URL, the user is properly directed to the login page, and can launch apps. We've restarted the service, and rebooted the server. We haven't yet tried uninstalling and reinstalling the software. Before we do this, I'm looking for ideas as to how we can get the redirect working again without a fairly major outage window. To make things more interesting, many of our users have Citrix Receiver installed, also pointed at https://citrix.company.com/. Receiver makes itself the default launcher for ICA files, and gives a connection error when it tries to load apps - probably because of the same non-functional rediect?

  • lighttpd with multiple IPs, each with a UCC certificate and many hostnames

    - by Dave
    I'd like to get lighttpd working with UCC certificates, but I can't seem to figure out the correct syntax. Essentially, for each IP address, I have one UCC certificate and a bunch of hostnames. $SERVER["socket"] == "10.0.0.1:443" { ssl.engine = "enable" ssl.ca-file = "/etc/ssl/certs/the.ca.cert.pem" ssl.pemfile = "/etc/ssl/private/websitegroup1.com.pem" $HTTP["host"] =~ "mywebsite.com" { server.document-root = /var/www/mywebsite.com/htdocs" } The above code works fine for one hostname, but as soon as I try to set up another hostname (note the same SSL cert): $SERVER["socket"] == "10.0.0.1:443" { ssl.engine = "enable" ssl.ca-file = "/etc/ssl/certs/the.ca.cert.pem" ssl.pemfile = "/etc/ssl/private/websitegroup1.com.pem" $HTTP["host"] =~ "anotherwebsite.com" { server.document-root = /var/www/anotherwebsite.com/htdocs" } ...I get this error: Duplicate config variable in conditional 6 global/SERVERsocket==10.0.0.1:443: ssl.engine Is there any way I can put a conditional so that only if ssl.engine is not already enabled, enable it? Or do I have to put all my $HTTP["host"]s inside the same $SERVER["socket"] (which will make config file management more difficult for me) or is there some entirely different way to do it? This has to be repeated for multiple IPs too (so I'll have a bunch of SERVER["socket"] == 10.0.0.2:443" etc), each with one UCC cert and many hostnames. Am I going about this the wrong way entirely? My goal is to conserve IP addresses when I have many websites that are related and can share an SSL certificate, but still need their own SSL-accessible version from the appropriate hostname (instead of a single secure.mywebsite.com).

  • Windows Server 2008 Antivirus Software with an API

    - by Dave Jellison
    I'm looking for an Antivirus package that is compliant with Windows Server 2008. That's not the hard part. What I need is an API layer on the Antivirus that i can call from managed .net code. For example: I am developing an Asp.Net (C#) website that allows users to upload files to the web server which the web site resides on. We have full control of the server so there are no security/rights issues on the server. I need to be able to run the antivirus algorithm on the newly uploaded files without (hopefully) shelling out to a command-ilne version of the software. Does anyone know of such a package?

  • How do I get a chart in LibreOffice Calc to have regular time intervals when the data is not regular?

    - by Dave M G
    I have an area chart in LibreOffice Calc where I would like the X axis to be measured in one month intervals spaced evenly apart. The data going into the graph, however, is not regularly spaced at one month. There can be zero, one, or two entries in any given month. Right now, the chart is keeping the horizontal pacing of the data consistent and adjusting the X axis to accomodate, which is the reverse of what I want. In the example picture below, you can see that there is one data point in March, one in May, and two in June. Along the X axis, April is gone and June is taking up double the space. Instead of this, I'd like the months to stay the same spacing so there is April, May, and June, and for the data area of the chart to compress or extend horiozontally as necessary. I have tried editing the X axis and adjusting the time intervals, but this doesn't seem to do anything. Is what I'm after possible?

  • Is it possible to set the name of the current virtual desktop via commandline?

    - by Dave Vogt
    The utility wmctrl has the possiblity to list the names of all virtual desktops: % wmctrl -d 0 - DG: 3360x1200 VP: 0,0 WA: 0,0 3360x1199 Mail / Comm 1 * DG: 3360x1200 VP: 0,0 WA: 0,0 3360x1199 Web / Docs 2 - DG: 3360x1200 VP: 0,0 WA: 0,0 3360x1199 A 3 - DG: 3360x1200 VP: 0,0 WA: 0,0 3360x1199 B I would like to be able to change, from the commandline, the name of the current desktop to something else. This is possible by using some pagers, for example, but I couldn't find out how to do it from the command line. Update: the xprop utility seems to be able to set the desktop names, but I could not figure out the exact format to do so, yet: % xprop -root -f _NET_DESKTOP_NAMES 8s -set _NET_DESKTOP_NAMES asdf % xprop -root _NET_DESKTOP_NAMES _NET_DESKTOP_NAMES(UTF8_STRING) = "asdf", "Web / Docs", "A"

  • Creating an ec2 image on amazon fails at mkfs.ext3

    - by Dave Orr
    I'm trying to create an image of my ec2 instance in Amazon's cloud. It's been a bit of an adventure so far. I did manage to install Amazon's ec2-api-tools, which was harder than it seemed like it should have been. Then I ran: ec2-bundle-vol -d /mnt -k pk-{key}.pem -c cert-{cert}.pem -u {uid} -s 1536 Which returned: Copying / into the image file /mnt/image... Excluding: /sys/kernel/debug /sys/kernel/security /sys /proc /dev/pts /dev /dev /media /mnt /proc /sys /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/z25_persistent-net.rules /mnt/image /mnt/img-mnt 1+0 records in 1+0 records out 1048576 bytes (1.0 MB) copied, 0.00677357 s, 155 MB/s mkfs.ext3: option requires an argument -- 'L' Usage: mkfs.ext3 [-c|-l filename] [-b block-size] [-f fragment-size] [-i bytes-per-inode] [-I inode-size] [-J journal-options] [-G meta group size] [-N number-of-inodes] [-m reserved-blocks-percentage] [-o creator-os] [-g blocks-per-group] [-L volume-label] [-M last-mounted-directory] [-O feature[,...]] [-r fs-revision] [-E extended-option[,...]] [-T fs-type] [-U UUID] [-jnqvFKSV] device [blocks-count] ERROR: execution failed: "mkfs.ext3 -F /mnt/image -U 1c001580-9118-4a50-9a25-dcf02be6d25f -L " So mkfs.ext3 wants -L, which is a volume name. But ec2-bundle-vol doesn't seem to take in a volume name as an argument, and the docs (http://docs.amazonwebservices.com/AmazonEC2/gsg/2006-06-26/creating-an-image.html) don't seem to think one should be needed. Certainly their sample command: # ec2-bundle-vol -d /mnt -k ~root/pk-HKZYKTAIG2ECMXYIBH3HXV4ZBZQ55CLO.pem -u 495219933132 -s 1536 doesn't specify anything. So... any help? What am I missing?

  • IIS cannot access itself

    - by dave
    We are on a corporate network that uses ISA and I am having issues trying to not have requests go through ISA. I have IIS7 on my local Windows 7 machine that has websites and a service layer. The websites access the service layer using a xxxx.servicelayer.local address that is set up in my HOSTS file to point to 127.0.0.1. I have Windows Firewall client which I have disabled. I have tried both adding this address into IE so that it does not go through ISA and also disabled this section altogether. When the website (which is actually IIS making the request to itself) tries to access the service layer I receive an ISA error that proxy authentication has failed. Considering that everything I can see to configure is set to not go through the proxy, ISA, I cannot see how this is actually going through the proxy and giving this error. Is there something within Windows 7 that forces the proxy setting, some sort of caching or similar?

  • Using a named pipe to simulate a serial port on a VMware virtual machine (linux host and client)

    - by Dave M
    Trying to write a python program to create a simulated data stream and feed it, through a named pipe, to a VMware virtual machine. The host is running Ubuntu 11.10 and VMware player 5.0.0. The Vm is running Ubuntu netbook 10.04. I am able to get the pipe working on the local machine but I am not able to get the pipe to pass data through the virtual serial port to the programs running on the virtual machine. #!/usr/bin/python import os # # Create a named pipe that will be used as the serial port on a VMware virtual machine SerialPipe = '/tmp/gpsd2NMEA' try: os.unlink(SerialPipe) except: pass os.mkfifo(SerialPipe) # # Open the named pipe NMEApipe = os.open(SerialPipe, os.O_RDWR|os.O_NONBLOCK) # # Write a string to the named pipe NMEAtime = "235959" os.write(NMEApipe, str( '%s\n' % NMEAtime )) Test to see if the python program is working on the host machine (displays 235959 if data is passing through the pipe) $ cat /tmp/gpsd2NMEA 235959 Serial port as defined in the VMware .vmx file: serial0.present = "TRUE" serial0.startConnected = "TRUE" serial0.fileType = "pipe" serial0.fileName = "/tmp/gpsd2NMEA" serial0.pipe.endPoint = "client" serial0.autodetect = "FALSE" serial0.tryNoRxLoss = "TRUE" serial0.yieldOnMsrRead = "TRUE" Test to see if the serial port in the VM is receiving data $ cat /dev/ttyS0 or $ minicom -D /dev/ttyS0 or $ stty -F /dev/ttyS0 cs8 -parenb -cstopb 115200 $ echo < /dev/ttyS0 None of these display any data from the python program.

  • New build won't boot: some fans turning, no beep or video

    - by Dave
    When my new system is powered up, the case fan and power supply fans turn fine. The CPU fan twitches, but never gets going. Although I've heard that with AMDs and Gigabyte motherboards that is not necessary a problem. Hard drive is spinning. However, there is absolutely no indication that anything else is happening. The motherboard, as far as I can tell, does not have an internal speaker, but I harvested one from another machine and plugged it in and still no beeps at all. The monitor screen stays black, on both the integrated VGA and DVI. This is a brand new build, and has never successfully booted. My parts are: AMD Athlon II X2 245 Regor 2.9GHz Socket AM3 65W Dual-Core Processor Model ADX245OCGQBOX - includes CPU cooler) GIGABYTE GA-MA785GPMT-UD2H AM3 AMD 785G HDMI Micro ATX AMD Motherboard - Retail G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL8D-4GBRM - Retail CORSAIR CMPSU-400CX 400W ATX12V V2.2 80 PLUS Certified Compatible with Core i7 Power Supply - Retail SAMSUNG Spinpoint F3 HD502HJ 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive COOLER MASTER Elite 341 RC-341C-KKN1-GP Black Steel MicroATX Mid Tower Computer Case - Retail I also have a DVD burner, but it acts the same whether that is plugged in or not. I'm using the on board video. What I've tried so far: I've switched power supplies, with no difference. I've tried different monitors (of which all are working on other machines) with no difference. I have tried putting it one memory module at a time, with no difference. I have tried the absolute minimum I can think of (power supply into motherboard, power button ONLY plugged into front panel, CPU fan plugged in), with no difference. I appreciate any ideas anyone might have. Do I need to RMA the motherboard? This is my first build, so there might be something obvious. I was very careful in assembly with static; I'm confident nothing was zapped during assembly.

  • Virsh: Different XML with edit than dumpxml. Why?

    - by Dave Vogt
    I'm trying to fetch the VNC access data from a virtual machine managed by libVirt. However, when I run virsh dumpxml $machine, the vnc passwd is missing: <graphics type='vnc' port='-1' autoport='yes'/> Checking the same using virsh edit $machine, I see the password is actually there: <graphics type='vnc' port='-1' autoport='yes' passwd='asdf'/> Why is this? Is this intentional (what reason?), or could this be a bug?

  • How do I convert an animated GIF to a YouTube friendly video format?

    - by Dave Webb
    My son has made some animations with Pivot Stickfigure Animator which we'd like to upload to YouTube. The problem is Pivot saves as animated GIFs which I can't upload to YouTube. The Wikipedia article recommends using Windows Movie Maker to convert GIF to WMV, but unfortunately I'm using Windows 7 for which you can get the new Windows Live Movie Maker which doesn't seem to support GIFs. I Googled and found an article which said to use Beneton Movie GIF to convert animated GIF to AVI, but this seemed to rely on a 3rd Party application which wasn't installed and so failed. Installing the missing application - pjBmp2Avi - by hand and adding it to the path still didn't allow Beneton to do the conversion. I hoped FFmpeg might do the trick but this only outputs to animated GIFs, it won't read from then. Further Googling found lots of applications with 30 day trials and so on but I was hoping for something free. So any suggestions on how I can convert an animated GIF to a movie file on Windows using free (as in beer) software?

  • Windows 2000 under Windows 7 Virtual PC not working correctly

    - by dave
    I have just moved my Windows 2000 Virtual PCs from Vista to Windows 7 Professional (64-bit). The machines work to a point but I have found some problems: drive mapping does not seem to work any more. I need this to exchange data. I do not need network access to the virtual PC so would rather leave it unconnected. the virtual PC would automatically shutdown the session and go to the login screen after a few minutes of inactivity. I tried installing the Virtual PC Integration Components but the install failed (one of the messages basically says it's XP+ only). Now I'm stuck in 640x480 mode with mouse capture. I have heard that you can install an older version of the Integration Components but this sounds a bit suspect. Does anyone have any ideas on how to get Windows2000 working with drive sharing on a Virtual PC?

  • Junior admin - how to discover/map the network to increase understanding?

    - by Dave
    I am a junior admin and have been tasked with gaining an understanding of the network. The 2nd line team are somewhat condescending so I'd rather not ask them. I know and use some of the servers on the network, so am able to tracert/ping them to see the names/addresses of equipment there are along the way, and gradually build a map, but how do I put the feelers out to find out what's out there if I don't know the names of server etc?

  • Is there a way to suppress keyboard sounds picked up by a desktop microphone in Windows 7?

    - by Dave Andersen
    The problem I'd like to solve is that my desktop microphone picks up all my keystrokes very loudly compared with my voice. Even just lightly tapping a key without depressing it causes a loud click to be picked up. I'd like a way to filter out this type of sound, while picking up voice normally. Is there any software input equalizer/filter that could do this? Or alternatively, some sort of hardware hack?

  • Windows Vista - Can't start any program without choosing "Run as administrator"

    - by Dave Forgac
    A friend called me saying that her computer recently said it was applying a Windows update when it was shutting down. Now when logged in as her normal user whenever she tries to run any program from the start menu or from a shortcut on the desktop she gets the following popup: "Windows cannot access the specified device path or file You may not have the appropriate permissions to access the item" If she right-clicks and chooses 'Run as administrator' the program will run. We checked the Windows update history and it said the update was applied successfully and that there are no updates available. Unfortunately I'm in a different city so I don't have physical access to the system to look at it any further. Has anyone had a similar problem or have any suggestions?

  • Publishing an Excel spreadsheet using Microsoft SBS 2008 to a web page that is viewable by mobile ph

    - by Dave Heath
    I am getting well out of my “superuser” depth here and would love some support. At work we have an Excel workbook (*.xls format circa Office 2003) which maintains our “engineers” timesheet. This handles what events we are doing across the year and how many “work units” it is. As far as a workbook goes, it is fairly simple with just a few =SUM(range) cells and some linked across sheets (12 sheets, one for each month) It is stored on a server, in a folder that provides “management” with full access and “engineers” with read-only access. The workbook itself is read-only for “engineers” and full access for “management”. I think these permissions are controlled through Active Directory. The workbook is protected with a password, assumingly to allow “management” to edit it even if they are working at a terminal logged in as an “engineer”. This protection prevents “engineers” from going to certain cells to see formulae and therefore editing them. The workbook has a macro which saves and closes it ten minutes after opening. This is to stop other “management” from being locked out by any one person who has logged in with editing privileges. I hope this is making sense to someone... :S Now then, we have Microsoft Small Business Server 2008. We have a shiny new web-based login for when we are offsite so we can get to Exchange webmail and our internal site (which uses Sharepoint 3.0). “Management” would like to be able to publish this timesheet automatically after changes (they don’t want to have to do anything different to what they are currently doing) so that using an iPhone “engineers” can check on it while out of the office. I am currently having a look at “Excel Services” for Office 2007 on TechNet but I am not sure if I am running down the right garden path at the moment. < EDIT This seems to suggest that I have to have Sharepoint Server 2007, with no mention of Sharepoint 3.0... ... "MOSS builds on WSS by adding both core features as well as end user web parts" - Wikipedia entry for Microsoft Office SharePoint Server (MOSS) this is not good news... "...and using the ASP.NET APIs, web parts can be written to extend the functionality of WSS." Wikipedia entry for Windows Sharepoint Services. Could this bring back what I need? Is this good news? Do I need to start learning ASP.NET? This link here implies that we need MOSS to do what I want and the bosses say we aint' getting it. http://serverfault.com/questions/20198/what-is-some-cool-things-you-can-do-with-sharepoint-2007/22128#22128 Back to the drawing board. < /EDIT Please could someone suggest some “further reading” for me to help point me in the right direction or to put me back on the right track. Many thanks. I will try to keep this up to date with how I get on.

  • Bouncing between a 502 and 503 error

    - by Dave
    This has become an increasingly frustrating ordeal. I'm mostly a web developer, so forgive me if I am using improper terminology here. I have a client that had purchased a domain at JustHost. We built him a website and have it on our own server space. Now, I'm mostly used to dealing with godaddy and it is simple enough to manage dns records and point the A record to our server IP, where Apache on our end deals with the domains via name-based virtual hosts. But for some reason, in setting this up with JustHost, when attempting to go to the domain name, I either get a 502 or 503 error or "webpage does not exist". Now, I know that the basic functionality of the webpage must be working because I can access the the index etc straight through my servers www data (IE [server-ip]/website_folder). I was on the phone with technical support for over three hours yesterday with justhost and the best I could get was "That's really weird..." I've checked my logs and there doesn't seem to be anything coming through to my end. Does anybody have an idea of whats going on here? I would love for it to be a problem on my end, because justhost doesn't seem capable of helping further. Any help is greatly appreciated, thanks. I forgot to mention that we have several other sites up and running and completely accessible.

  • New to building computers worried about temps

    - by dave
    I'm new to building my own computers and I was wondering about maximum temperatures. I understand that the room temp can affect the computers temp but how relevent is it? I understand that if my room temp is 20°C none of my computer parts could be lower than that. But if my room is 27°C instead of 20°C would this cause my computers parts to heat up more/faster? My new computer I built myself for gaming is i7 2600k 16gb ram ddr3 1600 hd6970 2 gb 240gb ssd ( bought a nas with 3 2tb drives in raid 5 for my home network ) 850w modular psu I also have my old hp computer i3 2120 8gb ram hd6770 1tb hdd I also have 3 laptops in my household, but I am not worried about their temps, they heat up my legs but they are never under stress. Due to size and money reasons I used an old case and it only has one of the sides left on it. Is this bad for the computer and will the extra dust cause problems? Or should I leave it this way or take the missus wrath and buy a case? If so is there any certain case I should get? I don't care about looks I just want card reader and usb slots and for it to run as cool or cooler than now, my case has 1 fan. Also what are the max temps for my new and old computer parts? Is 40°C under load ok for my CPU, what about 70°C for my GPU is that ok too, or should I worry? What are normal and safe temps for my components? I have looked around but there seem to be lots of different answers. I know that 100°C is bad but I want my parts to last as long as possible and this site always seems to give good replies without arguing or flaming.
