  • Problem installing Exchange Server [closed]

    - by Carlos
    I can't connect to the instance of exchange server 2010 through EMC on the local machine running w2k8 r2. I've checked all the default website bindings, the kerberos auth and WSMan are set to native type in powershell and I still get this error message. Connecting to remote server failed with the following error message: The WS-Management service does not support the request. It was running the command 'Discover-ExchangeServer -UseWIA $true -suppresserror $true'

  • Resizing Partitions on Live RHEL/cPanel Server

    - by Timothy R. Butler
    I've resized many partitions over the years on Linux, Windows and Mac OS X -- but always using a GUI. However, the time has come where the preset partition sizes my data center placed on my server aren't the right sizes and I need to resize a production server's disks. I could fiddle with it and probably do OK, but given that it is a production server, I wanted to get some advice about the right way to do this. I do have KVM over IP access, so if it is best to take the server offline and boot off a rescue partition, I can do that. root [/var/lib/mysql]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 9.9G 2.1G 7.3G 23% / tmpfs 7.8G 0 7.8G 0% /dev/shm /dev/sda1 99M 77M 18M 82% /boot /dev/sda8 884G 463G 376G 56% /home /dev/sda3 9.9G 8.0G 1.5G 85% /usr /dev/sda5 9.9G 9.1G 308M 97% /var /usr/tmpDSK 2.0G 38M 1.8G 3% /tmp As you can see /var and /usr are quite close to being full and I've actually had to symlink some logs on /usr to directories in /home to balance things out. What I would like to do is to add 6-10 GB each to /usr and /var, presumably taking the space from /home. As I think about how the disk is arranged, the best thought I've come up with is to reduce /home by 16 GB, say, and move /var to the spot freed up, then allocating /var's space to /usr. However, that would put /var at the far end of the disk, which seems less than idea, given that MySQL has all of its data on that partition. I'd love to take the space out of the closer end of /usr, but I assume that would take a very arduous (and perhaps risky) process of moving all of the data in /usr around. I seem to recall having such a process fail for me on a computer in the past. The other option might be to merge / and /usr since / is underutilized, though I'm not sure if that's a good idea. Do you have any suggestions both on the best reallocation plan and the commands to use to accomplish it? UPDATE: I should add -- here's the partition table. There's one unused partition, which, if memory serves, was the original tmp location before I created a tmp image: Name Flags Part Type FS Type [Label] Size (MB) ------------------------------------------------------------------------------ Unusable 1.05* sda1 Boot Primary Linux ext2 106.96* sda2 Primary Linux ext3 10737.42* sda3 Primary Linux ext3 10737.42* sda5 NC Logical Linux ext3 10738.47* sda6 NC Logical Linux swap / Solaris 2148.54* sda7 NC Logical Linux ext3 1074.80* sda8 NC Logical Linux ext3 964098.53*

  • Jquery Accordion and Fading

    - by Slick Willis
    I am trying to create a jquery accordion that fades the header of the accordion out when the page is loaded then fades it in when the mouse hovers. The accordion also opens when the mouse hovers. I am able to get all of this working, the problem I am having is when the accordion opens the header moves away and the mouse is no longer on it to keep it lit. I would like the links to keep the header lit as well as if the mouse is on the header itself. Below is the code that I wrote for it. <html> <head <script type='text/javascript' src='http://accidentalwords.squarespace.com/storage/jquery/jquery-1.4.2.min.js'></script> <script type='text/javascript' src='http://accidentalwords.squarespace.com/storage/jquery/jquery-custom-181/jquery-ui-1.8.1.custom.min.js'></script> </head> <body bgcolor="black"> <style = "css/text"> .links { font-family: "Georgia", "Verdana", serif; line-height: 30px; margin-left: 20px; margin-top: 5px; } .Title { font-family: "Geneva", "Verdana", serif; font-weight: bold; font-size: 2em; text-align: left; font-variant: small-caps; border-bottom: solid 2px #25FF00; padding-bottom:5px; margin-bottom: 10px; } </style> <script type="text/javascript"> $(document).ready(function(){ $(".Title").fadeTo(1,0.25); $(".Title").hover(function () { $(this).stop().fadeTo(250,1) .closest(".Title").find(".links").fadeTo(250,0.75); }, function() { $(this).stop().fadeTo(250,0.25); }); }); $(function() { $("#accordion").accordion({ event: "mouseover" }); }); </script> <p>&nbsp</p> <div id="accordion"> <div class="Title"><a href="#"STYLE="TEXT-DECORATION: NONE; color: #25FF00;">Reference</a></div> <div class="links"> <a href="http://docs.jquery.com/Main_Page" STYLE="TEXT-DECORATION: NONE; color: #25FF00;">Jquery Documentation/Help</a><br> <a href="http://stackoverflow.com/" STYLE="TEXT-DECORATION: NONE; color: #25FF00;">Stack Overflow</a><br> <a href="http://www.w3schools.com/" STYLE="TEXT-DECORATION: NONE; color: #25FF00;">w3schools.com</a><br> </div> <div class="Title"><a href="#"STYLE="TEXT-DECORATION: NONE; color: #FF7200;">Gaming</a></div> <div class="links"> <a href="http://docs.jquery.com/Main_Page" STYLE="TEXT-DECORATION: NONE; color: #FF7200;">Jquery Documentation/Help</a><br> <a href="http://stackoverflow.com/" STYLE="TEXT-DECORATION: NONE; color: #FF7200;">Stack Overflow</a><br> <a href="http://www.w3schools.com/" STYLE="TEXT-DECORATION: NONE; color: #FF7200;">w3schools.com</a><br></div> <div class="Title"><a href="#"STYLE="TEXT-DECORATION: NONE; color: #00DEFF;">Grub</a></div> <div class="links"> <a href="http://docs.jquery.com/Main_Page" STYLE="TEXT-DECORATION: NONE; color: #00DEFF;">Jquery Documentation/Help</a><br> <a href="http://stackoverflow.com/" STYLE="TEXT-DECORATION: NONE; color: #00DEFF;">Stack Overflow</a><br> <a href="http://www.w3schools.com/" STYLE="TEXT-DECORATION: NONE; color: #00DEFF;">w3schools.com</a><br> </div> <div class="Title"><a href="#"STYLE="TEXT-DECORATION: NONE; color: #F8FF00;">Drinks</a></div> <div class="links"> <a href="http://docs.jquery.com/Main_Page" STYLE="TEXT-DECORATION: NONE; color: #F9FF00;">Jquery Documentation/Help</a><br> <a href="http://stackoverflow.com/" STYLE="TEXT-DECORATION: NONE; color: #F8FF00;">Stack Overflow</a><br> <a href="http://www.w3schools.com/" STYLE="TEXT-DECORATION: NONE; color: #F8FF00;">w3schools.com</a><br> </div> </div> </body> </html>

  • 403 forbidden while submitting a POST request with image data via iPhone application

    - by binnyb
    I am creating an iOS application which allows users to send image/text data to my webserver via a POST request. I am successfully sending POSTS to the server when image data is not included in the request. Any time i POST with image data the server spits back a 403 forbidden. I have tried adding the following to the .htaccess file in the directory of the script with no luck: Options +Indexes FollowSymLinks +ExecCGI Order allow,deny Allow from all web browsers and Android devices can successfully POST with image data to the script, the only device which cannot is the iPhone. POSTING with data to other hosting providers works as expected - it is just this host(ipowerweb.com). i noticed that when i try to POST to ANY script on the server with data returns a 403 forbidden. another note: i can successfully post to another server that is hosted by ipowerweb, but mine cant seem to handle it. My host has tried to resolve the issue but cannot, and they have marked it on their end as "resolved", so no more help from them. I wish to keep this host as moving would be a pain - i will change hosts as a last resort, so please help me! Why am i getting this 403 forbidden error only when i submit data via my iPhone application? How can i resolve the issue so i can successfully POST data? any advice on what i can do would be greatly appreciated. edit: as request, here are the response headers: { Connection = close; "Content-Length" = 217; "Content-Type" = "text/html; charset=iso-8859-1"; Date = "Wed, 12 Jan 2011 19:11:19 GMT"; Server = "Apache/2"; } edit: as request here are the request headers(oops): { "Accept-Encoding" = gzip; "Content-Length" = 5781; "Content-Type" = "multipart/form-data; charset=utf-8; boundary=0xKhTmLbOuNdArY"; "User-Agent" = "YeahIAteThat 1.0 (iPhone; iPhone OS 4.2.1; en_US)"; }

  • Why does one loop take longer to detect a shared memory update than another loop?

    - by Joseph Garvin
    I've written a 'server' program that writes to shared memory, and a client program that reads from the memory. The server has different 'channels' that it can be writing to, which are just different linked lists that it's appending items too. The client is interested in some of the linked lists, and wants to read every node that's added to those lists as it comes in, with the minimum latency possible. I have 2 approaches for the client: For each linked list, the client keeps a 'bookmark' pointer to keep its place within the linked list. It round robins the linked lists, iterating through all of them over and over (it loops forever), moving each bookmark one node forward each time if it can. Whether it can is determined by the value of a 'next' member of the node. If it's non-null, then jumping to the next node is safe (the server switches it from null to non-null atomically). This approach works OK, but if there are a lot of lists to iterate over, and only a few of them are receiving updates, the latency gets bad. The server gives each list a unique ID. Each time the server appends an item to a list, it also appends the ID number of the list to a master 'update list'. The client only keeps one bookmark, a bookmark into the update list. It endlessly checks if the bookmark's next pointer is non-null ( while(node->next_ == NULL) {} ), if so moves ahead, reads the ID given, and then processes the new node on the linked list that has that ID. This, in theory, should handle large numbers of lists much better, because the client doesn't have to iterate over all of them each time. When I benchmarked the latency of both approaches (using gettimeofday), to my surprise #2 was terrible. The first approach, for a small number of linked lists, would often be under 20us of latency. The second approach would have small spats of low latencies but often be between 4,000-7,000us! Through inserting gettimeofday's here and there, I've determined that all of the added latency in approach #2 is spent in the loop repeatedly checking if the next pointer is non-null. This is puzzling to me; it's as if the change in one process is taking longer to 'publish' to the second process with the second approach. I assume there's some sort of cache interaction going on I don't understand. What's going on?

  • Secret, unlogged, transparent, case-sensitive proxy in IIS6?

    - by Ian Boyd
    Does IIS have a secret, unlogged, transparent, case-sensitive proxy built into it? A file exists on the web-server: GET http://www.stackoverflow.com/javascript/ModifyQuoteArea.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:20:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... Problem is that a changes made to the file will not get served, the old (i.e. February of last year) version keeps getting served: HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:23:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... The same old file gets served, even though we've: renamed the file deleted the file restarted IIS The request for this file does not appear in the IIS logs (e.g. C:\WINNT\System32\LogFiles\W3SVC7\) And this only happens from the outside (i.e. the internet). If you issue the request locally on the server, then you will: - get the current file (file there) - 404 (file renamed) - 404 (file deleted) But if i change the case of the requested resource, i.e.: GET http://www.stackoverflow.com/javascript/MoDiFyQuOtEArEa.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com Note: MoDiFyQuOtEArEa.js verses ModifyQuoteArea.js Then i do get the proper file (or get the 404 as i expect if the file is renamed or deleted). But any subsequent changes to the file will not show up until i change the case of the file i'm asking for. Checking the IIS logs all indicate that the (internet) requests are all coming the correct client on the internet (i.e. not from some intermediate proxy). Since the file doesn't exist on the hard drive anymore, i conclude that there is a proxy. The requests serviced from this proxy are not logged in the IIS logs. The requests for new files are logged, and from the client IP, not a proxy IP. The proxy is case sensitivie. This does not sound like something Microsoft, or IIS, would do: - a transparent proxy - case-sensitivie - unlogged - surviving restarts of IIS - surviving in a cache for hours i can't believe that our customer's IIS is doing these things. i'm assuming there is some other transparent proxy in front of IIS. Or, does IIS have a transparent, unlogged, case-sensitive, memory based, proxy, that caches content for at least 7 hours? (Come Monday morning, IIS is serving the correct file, unlogged).

  • keyboard mappings are totally screwed after updating to kde4

    - by zeonglow
    I recently upgraded from KDE 3.5 to KDE 4, and I have been having weird issues with my keyboard. In one of the virtual consoles e.g. when I press ctrl + alt 1 , I can type perfectly, but in KDE, several of the number keys don't work, the left and right arrows don't work either. When I press the right arrow key in xev I get this: KeyRelease event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 903459, (111,55), root:(115,836), state 0x10, keycode 114 (keysym 0x1008ff11, XF86AudioLowerVolume), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False When I press the '3' key it toggles my Bookmarks toolbar in Firefox, in xev I get this: KeyPress event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 999968, (94,115), root:(98,896), state 0x10, keycode 12 (keysym 0x1008ff30, XF86Favorites), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 1000032, (94,115), root:(98,896), state 0x10, keycode 12 (keysym 0x1008ff30, XF86Favorites), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False As this is deeper down, changing the type of keyboard in the KDE meun's has no effect. I'm slowly beginning to wade through the mountains of documentation about the X keyboard model, but there has to be a better way. Does anyone no what it is? Edit: 1234567890 ! after deleting the entire .kde folder. but only until I change the Keyboard settings from the "system settings" applet, then its hosed full time. Regardless of what I set the settings too. (restore to default settings doesn't) 2nd Edit: I'm using Gentoo AMD64, I was upgrading from KDE 3.5 KDE 4.2. I think I had manual settings before, although I didn't change anything. I was originally running KDE without HAL until that stop working a year or so ago. The only customisation I made was to set the multimedia keys to control Amarok. 3rd Edit $ grep xkb /var/log/Xorg.0.log (**) Option "xkb_rules" "evdev" (**) Option "xkb_model" "evdev" (**) Option "xkb_layout" "us" (**) Option "xkb_rules" "evdev" (**) Option "xkb_model" "evdev" (**) Option "xkb_layout" "us" Xorg.0.log has this to say: (WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.

  • On-demand RHEL/Centos Linux admin and MySQL admin

    - by user1322092
    Could you share with me a few reputable businesses/websites where I can quickly onboard a RHEL/Centos Linux admin or even a MySQL admins (say if I need help with disaster recovery). I have a cloud server, and I would like to task an admin to perform specific maintenance or even periodic. With the abundance of solely-run cloud servers, I would imagine there's a demand for this type of service (certainly for me).

  • google docs document in Hebrew and English?

    - by JoelFan
    Is there any way to have Hebrew and English in the same document in Google Docs? So far, everything I have found about multiple languages seems to assume that you want the user interface (menus, etc) and document text in the same language, and that you only want that one language. I would like the interface to stay in English but let me type Hebrew and English into the document text.

  • Losing internet connectivity on server after installing LogMeIn Hamachi (with server set as gateway node)

    - by Kim Jong-Un
    Our domain controller (SBS 2003) completely lost internet and network connectivity yesterday after I remotely installed LogMeIn Hamachi on it and set it to be a gateway node- in an attempt to create a VPN link between the server and a remote site. I had to go in to the office to resolve the problem as, unsurprisingly, my own remote access to the server was also lost. I was only able to restore network connectivity by deleting a virtual network adapter Hamachi created when making the server the gateway node (called "Hamachi bridge" I believe), then rebooting the server. This is a repeatable problem. Every time I try to get this to work, it just takes the server offline. Why would this bridge affect regular TCP/IP connectivity on the NIC in this way? I have tried a "hub-and-spoke" configuration between the server and our PC at a remote site (server set as hub, remote site as spoke). This caused no such problems with general internet connectivity, and file transfer worked well between the two computers. However, there was a DNS issue with the VPN between the two sites- resulting in Active Directory not being able to communicate between them (could not log on using domain user accounts at remote site if they were not already cached on that machine). I only tried a "gateway" network as LogMeIn support told me: If you can get the Active Directory to work it would only be through a "Gateway" network type with the server acting as the Gateway Node. You would configure the gateway settings on the server in the Hamachi client on that machine to push whatever IP's/DNS settings you prefer and at that point AD would be able (all things being equal) communicate to the client node when it attaches. We do not have any ActiveDirectory configuration info as that's outside the scope of our support. I hope this helps. It would be fantastic if I could get Active Directory to work over a Hamachi VPN connection, without worrying about the server going offline in this way. Does anyone have any ideas how I should proceed, or any theories as to what is going on when I try to use the "gateway" network type? I want to try to narrow down what is going on here.
