  • Windows 2012 VPN setup without Active Directory

    - by iss42
    I have followed the guide here: http://www.youtube.com/watch?v=9qbpxKRb-94 But my situation differs with respect to there being no AD (Active Directory) setup. When I try to connect I get this in the server event log: "The user xx connected from x.x.x.x but failed an authentication attempt due to the following reason: The account does not have permission to dial in." Is there a way to enable this without AD?

    I am trying to get postfix working, and when I test it using mail user I enter the subject, message, ect and get the following error: mail: /usr/sbin/sendmail: No such file or directory Can't send mail: sendmail process failed Why is it talking about sendmail?

  • IIS 7 doesn't do a 301 redirect

    - by rohde
    Hi there! I have just migrated some sites to IIS7 from IIS6, and am experiencing problems with one of the sites. When a request comes in for the site (www.ourdomain.com/site1/) with a trailing slash everything is fine. But if the trailing slash is left out (www.ourdomain.com/site1), then the request fails. Apparently it doesn't do a 301 redirect on the slashl-less URL, resulting in ASP.NET throwing an exception. This is not happening with the other sites at the same domain. What can be the cause of this? EDIT: The exception I get is this: System.Web.HttpException: Failed to Execute URL. at System.Web.Hosting. ISAPIWorkerRequestInProcForIIS6.BeginExecuteUrl(String url, String method, String childHeaders, Boolean sendHeaders, Boolean addUserIndo, IntPtr token, String name, String authType, Byte[] entity, AsyncCallback cb, Object state) at System.Web.HttpResponse.BeginExecuteUrlForEntireResponse(String pathOverride, NameValueCollection requestHeaders, AsyncCallback cb, Object state) at System.Web.DefaultHttpHandler.BeginProcessRequest(HttpContext context, AsyncCallback callback, Object state) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

  • What ways are there to set permissions on an Exchange 2003 mailbox?

    - by HopelessN00b
    I'm having a difficult/impossible time tracing down a permissions issue on an Exchange 2003 mailbox, and I was wondering if I'm missing any technical possibilities here. The basic question is what ways are there to set a user's permissions to access a mailbox in Exchange 2003? I know of two. Permissions on the mailbox itself (Mailbox Rights) and having delegated rights. And then, if it's possible, how would one view all the permissions (including delegated permissions) on the mailbox? The situation is that a new user who's been set up "exactly like all the others" in his department (pretty sure he was copied via the right click option in ADUC, in fact) can't access a specific shared mailbox, which I've been assured about a dozen other people do have access to and access on a regular basis. As to how they got permissions to the mailbox, no one knows, so it must have been granted by a white wizard whose spell has since worn off, so now IT has to handle it instead. Anyway... This mailbox is a normal AD user, created as a service account, for which no one knows the password (of course), so it's probably not the case that this service account was being used to delegate permissions. Upon taking examining the Mailbox Rights directly... Here are the permissions I see: This leads me to believe that one of two things are happening - the managers have been delegating full mailbox permissions to the rest of the department, or everyone's logging in using... not their own account. But, before I get too excited about the prospect of busting out the LART and strolling over to that department, I want to make sure I'm not missing another possible explanation. Like most of the rest of the world, I ditched Exchange 2003 at the earliest possible opportunity, and had been looking forward to never seeing it again, so I'm a bit rusty on the intricacies of how it [mostly, sort of] works. Anyone see any or possibilities, or things I may have missed, or does the LART get to come out and play?

    - by Mark Milford
    Hi I have a windows server 2008 running in Parrallels (on Mac osx)... the mac crashed yesterday and so I hard rebooted it, when I fired up the Windows Server 2008 VM this morning it goes as far as the progress bar then goes black screen and does nothing else (even when left for a long time). I can boot into safe mode, Event Viewer says: "The following boot-start or system-start driver(s) failed to load: spldr stoflt" Any ideas? What should I do next?

  • Private IP getting routed over Internet

    - by WernerCD
    We are setting up an internal program, on an internal server that uses the private 172.30.x.x subnet... when we ping the address 172.30.138.2, it routes across the internet: C:\>tracert 172.30.138.2 Tracing route to 172.30.138.2 over a maximum of 30 hops 1 6 ms 1 ms 1 ms xxxx.xxxxxxxxxxxxxxx.org [192.168.28.1] 2 * * * Request timed out. 3 12 ms 13 ms 9 ms xxxxxxxxxxx.xxxxxx.xx.xxx.xxxxxxx.net [68.85.xx.xx] 4 15 ms 11 ms 55 ms te-7-3-ar01.salisbury.md.bad.comcast.net [68.87.xx.xx] 5 13 ms 14 ms 18 ms xe-11-0-3-0-ar04.capitolhghts.md.bad.comcast.net [68.85.xx.xx] 6 19 ms 18 ms 14 ms te-1-0-0-4-cr01.denver.co.ibone.comcast.net [68.86.xx.xx] 7 28 ms 30 ms 30 ms pos-4-12-0-0-cr01.atlanta.ga.ibone.comcast.net [68.86.xx.xx] 8 30 ms 43 ms 30 ms 68.86.xx.xx 9 30 ms 29 ms 31 ms 172.30.138.2 Trace complete. This has a number of us confused. If we had a VPN setup, it wouldn't show up as being routed across the internet. If it hit an internet server, Private IP's (such as 192.168) shouldn't get routed. What would let a private IP address get routed across servers? would the fact that it's all comcast mean that they have their routers setup wrong?

  • Is there a good Open Source alternative to the commercial software "Quicken"?

    - by Alex R
    I just need good solid double-entry / multi-account transactions with a variety of simple reports. I've previously used Quicken but their file and OS version compatibility issues are a nightmare. I need a software that will have a good chance of still opening the files I create today, several years from now. Quicken has failed me in this regard. So I figure anything that comes with source code is a safer bet.

  • Installing Heroku on Lucid Lynx reveals missing dependencies

    - by Sir Emeth
    I am trying to get a Ruby on Rails app hosted free somewhere, and Heroku is looking like my last resource. It is supposed to work on Linux, and the gem installs with no errors, but whenever I run any Heroku command it spits out several errors, all connected, and talking about a failed require. I looked it up in the code, and it says: require 'readline' That is it. I have tried to install every variation of libreadline that I can find and think of, but none of it makes any difference.

  • Why cache static files with Varnish, why not pass

    - by Saif Bechan
    I have a system runnning nginx / php-fpm / varnish / wordpress and amazon s3. Now I have looked at a lot of configuration files while setting up the system, and in all of them I found something like this: /* If the request is for pictures, javascript, css, etc */ if (req.url ~ "\.(jpg|jpeg|png|gif|css|js)$") { /* Remove the cookie and make the request static */ unset req.http.cookie; return (lookup); } I do not understand why this is done. Most of the examples also run NginX as a webserver. Now the question is, why would you use the varnish cache to cache these static files. It makes much more sense to me to only cache the dynamic files so that php-fpm / mysql don't get hit that much. Am I correct or am I missing something here? UPDATE I want to add some info to the question based on the answer given. If you have a dynamic website, where the content actually changes a lot, chaching does not make sense. But if you use WordPress for a static website for example, this can be cached for long periods of time. That said, more important to me is static conent. I have found a link with some test and benchmarks on different cache apps and webserver apps. http://nbonvin.wordpress.com/2011/03/14/apache-vs-nginx-vs-varnish-vs-gwan/ NginX is actually faster in getting your static content, so it makes more sense to just let it pass. NginX works great with static files. -- Apart from that, most of the time static content is not even in the webserver itself. Most of the time this content is stores on a CDN somewhere, maybe AWS S3, something like that. I think the varnish cache is the last place where you want to have you static content stored.

  • Simple mdadm RAID 1 not activating spare

    - by Nick Liu
    I had created two 2TB HDD partitions (/dev/sdb1 and /dev/sdc1) in a RAID 1 array called /dev/md0 using mdadm on Ubuntu 12.04 LTS Precise Pangolin. The command sudo mdadm --detail /dev/md0 used to indicate both drives as active sync. Then, for testing, I failed /dev/sdb1, removed it, then added it again with the command sudo mdadm /dev/md0 --add /dev/sdb1 watch cat /proc/mdstat showed a progress bar of the array rebuilding, but I wouldn't spend hours watching it, so I assumed that the software knew what it was doing. After the progress bar was no longer showing, cat /proc/mdstat displays: md0 : active raid1 sdb1[2](S) sdc1[1] 1953511288 blocks super 1.2 [2/1] [U_] And sudo mdadm --detail /dev/md0 shows: /dev/md0: Version : 1.2 Creation Time : Sun May 27 11:26:05 2012 Raid Level : raid1 Array Size : 1953511288 (1863.01 GiB 2000.40 GB) Used Dev Size : 1953511288 (1863.01 GiB 2000.40 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Mon May 28 11:16:49 2012 State : clean, degraded Active Devices : 1 Working Devices : 2 Failed Devices : 0 Spare Devices : 1 Name : Deltique:0 (local to host Deltique) UUID : 49733c26:dd5f67b5:13741fb7:c568bd04 Events : 32365 Number Major Minor RaidDevice State 1 8 33 0 active sync /dev/sdc1 1 0 0 1 removed 2 8 17 - spare /dev/sdb1 I've been told that mdadm automatically replaces removed drives with spares, but /dev/sdb1 isn't being moved into the expected position, RaidDevice 1. UPDATE (30 May 2012): A badblocks destructive read-write test of the entire /dev/sdb yielded no errors as expected; both HDDs are new. As of the latest edit, I assembled the array with this command: sudo mdadm --assemble --force --no-degraded /dev/md0 /dev/sdb1 /dev/sdc1 The output was: mdadm: /dev/md0 has been started with 1 drive (out of 2) and 1 rebuilding. Rebuilding looks like it's progressing normally: md0 : active raid1 sdc1[1] sdb1[2] 1953511288 blocks super 1.2 [2/1] [U_] [>....................] recovery = 0.6% (13261504/1953511288) finish=2299.7min speed=14060K/sec unused devices: <none> I'm now waiting on this rebuild, but I'm expecting /dev/sdb1 to become a spare just like the five or six times that I've tried rebuilding before. UPDATE (31 May 2012): Yeah, it's still a spare. Ugh! UPDATE (01 June 2012): I'm trying Adrian Kelly's suggested command: sudo mdadm --assemble --update=resync /dev/md0 /dev/sdb1 /dev/sdc1 Waiting on the rebuild now... My questions are: Why isn't the spare drive becoming active sync? How can I make the spare drive become active?

  • LogMeIn style remote access to NAS drive

    - by Mere Development
    I've been asked to setup some remote access to a NAS drive. The NAS drive will sit on a VLAN inside a network that uses a Cisco 891 IS router as gateway. The charity have no SSL-VPN licenses for the Cisco. At present there are no open ports or services on the Cisco itself and ideally we would like to keep it that way for a while, hence the request for a LogMeIn style service that's initiated from inside. We need multiple user access, about 10 max. Using LogMeIn on a machine connected to the NAS would only provide screen sharing I believe, and no concurrent connections (could be wrong?) The end users need to be able to read and write files to the NAS from Mac's and PC's around the globe. Read-only access from Mobile devices would be a bonus but not absolutely necessary. This is for a charity, non-commercial, but they are willing to spend if necessary. Cisco config knowledge is at a minimum so if I can avoid upsetting that delicate device I'll be happy :) Anyone have any clever ideas? I can provide more information on request. Thanks, Ben

  • Youtube "unable to convert video file"

    I encoded some videos from a dvd format (mpeg 2 I think) to h246 (using a .mkv container). When I upload them to youtube, most of them work, but there are a few that don't. After I upload it, I get the message "Failed (unable to convert video file)" What could be the problem because all the videos are the same format, and only a few of them fail. When I click upload details, while uploading, the file seems to be recognized by youtube: Format: MATROSKA Dimensions: 704 x 480 px Video codec: H264 Audio codec: AAC

  • Understanding tcptraceroute versus http response

    - by kojiro
    I'm debugging a web server that has a very high wait time before responding. The server itself is quite fast and has no load, so I strongly suspect a network problem. Basically, I make a web request: wget -O/dev/null http://hostname/ --2013-10-18 11:03:08-- http://hostname/ Resolving hostname... 10.9.211.129 Connecting to hostname|10.9.211.129|:80... connected.

So I try a tcptraceroute to see what's up: $ sudo tcptraceroute hostname 80 Password: Selected device en2, address 192.168.113.74, port 54699 for outgoing packets Tracing the path to hostname (10.9.211.129) on TCP port 80 (http), 30 hops max 1 192.168.113.1 0.842 ms 2.216 ms 2.130 ms 2 10.141.12.77 0.707 ms 0.767 ms 0.738 ms 3 10.141.12.33 1.227 ms 1.012 ms 1.120 ms 4 10.141.3.107 0.372 ms 0.305 ms 0.368 ms 5 12.112.4.41 6.688 ms 6.514 ms 6.467 ms 6 cr84.phlpa.ip.att.net (12.122.107.214) 19.892 ms 18.814 ms 15.804 ms 7 cr2.phlpa.ip.att.net (12.122.107.117) 17.554 ms 15.693 ms 16.122 ms 8 cr1.wswdc.ip.att.net (12.122.4.54) 15.838 ms 15.353 ms 15.511 ms 9 cr83.wswdc.ip.att.net (12.123.10.110) 17.451 ms 15.183 ms 16.198 ms 10 12.84.5.93 9.982 ms 9.817 ms 9.784 ms 11 12.84.5.94 14.587 ms 14.301 ms 14.238 ms 12 10.141.3.209 13.870 ms 13.845 ms 13.696 ms 13 * * * … 30 * * * I tried it again with 100 hops, just to be sure – the packets never get there. So how is it that the server does respond to requests via http, even after a minute? Shouldn't all requests just die? I'm not sure how to proceed debugging why this server is slow (as opposed to why it responds at all).

This is not supported yet.. /usr/sbin/grub-setup: error: embedding is not possible, but this is required for cross-disk install. root@answe:~# grub-install /dev/sdb Installation finished. No error reported. So 1) "update-grub" find only /sda and /sdb Linux, not /md0 2) "dpkg-reconfigure grub-pc" says "GRUB failed to install the following devices /dev/md0" I cannot load my system except from /sdb1 and /sda1, but in DEGRADED mode... Anybody can resolve this issue? I have big headache with this.

  • Why Wireshark does not recognize this HTTP response?

    - by Alois Mahdal
    I have a trivial CGI script that outputs simple text content. It's written in Perl and using CGI module and it specifies only the most basic headers: print $q->header( -type => 'text/plain', -Content_length => $length, ); print $stuff; There's no apparent issue with functionality, but I'm confused about the fact that Wireshark does not recognize the HTTP response as HTTP--it's marked as TCP. Here is request and response: GET /cgi-bin/memfile/memfile.pl?mbytes=1 HTTP/1.1 Host: 10.6.130.38 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: cs,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip, deflate Connection: keep-alive HTTP/1.1 200 OK Date: Thu, 05 Apr 2012 18:52:23 GMT Server: Apache/2.2.15 (Win32) mod_ssl/2.2.15 OpenSSL/0.9.8m Content-length: 1048616 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Content-Type: text/plain; charset=ISO-8859-1 XXXXXXXX... And here is the packet overview (Full packet is here on pastebin) No. Time Source srcp Destination dstp Protocol Info tcp.stream abstime 5 0.112749 10.6.130.38 80 10.6.130.53 48072 TCP [TCP segment of a reassembled PDU] 0 20:52:23.228063 Frame 5: 1514 bytes on wire (12112 bits), 1514 bytes captured (12112 bits) Ethernet II, Src: Dell_97:29:ac (00:1e:4f:97:29:ac), Dst: Dell_3b:fe:70 (00:24:e8:3b:fe:70) Internet Protocol Version 4, Src: 10.6.130.38 (10.6.130.38), Dst: 10.6.130.53 (10.6.130.53) Transmission Control Protocol, Src Port: http (80), Dst Port: 48072 (48072), Seq: 1, Ack: 330, Len: 1460 Now when I see this in Wireshark: there's usual TCP handshake then the GET request shown as HTTP with preview then the next packet contains the response, but is not marked as an HTTP response--just a generic "[TCP segment of a reassembled PDU]", and is not caught by "http.response" filter. Can somebody explain why Wireshark does not recognize it? Is there something wrong with the response?

  • Show full URI/URL in Chrome's developer tools Network tab

    - by Lev
    When using Chrome to debug, I find it incredibly difficult to be efficient due to the fact that I don't see how I can force the "Network" tab of the developer tools to show the full request URI. It will show the full URI if you hover the link and wait a second, but this is incredibly counterproductive. All of my AJAX requests are sent to ajax.php, and handled by using query string arguments, like: ajax.php?do=profile-set ajax.php?do=game-save ... etc. Since I use AJAX extensively, my network tab is filled with "ajax.php", but I have to manually hover each and every entry to find the request I am looking for. Surely there has got to be another way!? I am constantly fed up by something new in Firefox and immediately force myself back into Chrome, but it is always the developer tools in Chrome that keep me from using it for an extended period of time. Hopefully I can find out how to do this so I can continue using Chrome as my numero uno. I've provided a screen shot to show you where I mean:
