• What is a good web interface for remote linux load monitoring?

  - by Jakobud

  I'm looking for some type of remote linux monitoring software that you can view using a web interface. And I'm not just looking for the basic load information. I'm also looking for process information, similar to the info that you get from TOP. Like I'd just like to be able to pop open this webpage to view whats going on with the server at a moments notice. For example, perhaps just a basic PHP page that is on the server that uses basic AJAX to display and refresh results from the TOP command in the page. I was thinking about writing something like this, but I don't want to reinvent the wheel.

• Is Samba "remote browse sync" possible across OpenVPN tunnel?

  - by John Reynolds

  I'm connecting 2 TomatoUSB (Shibby build on WNR3500L v2) routers with an OpenVPN routed connection: ----------------------- ----------------------- | Router 1, subnet 20 | <--tunnel--> | Router 2, subnet 21 | ----------------------- ----------------------- Router 1 is the OpenVPN server and Router 2 is a client. Clients attached to the routers on both subnets can ping clients on the other subnet, so the tunnel and routing works. I've enabled file sharing on both, in order to get their Samba WINS servers running. Is it possible to get name resolution across the tunnel? I've tried remote browse sync = 192.168.21.1 in /etc/smb.conf on the server side, to no avail. Also tried using the IP adress that the client gets from the OpenVPN address pool (usually 10.8.0.something), but still no joy.

• How to print index in a 'for-loop' being executed in remote host through SSH?

  - by YShin

  I want to ssh into a remote host, and then execute a for loop that goes through sequence of numbers to control number of different nodes. ssh user@host /bin/bash << EOF for i in {1..10} do echo $i done EOF If I do this, the output is just 10 blank lines, instead of printing out numbers from 1 through 10. If I execute same code on my local machine, I get the desired output which is ten lines each line printing from 1 through 10. How would one achieve the intended functionality, that is accessing the index in a for loop that is being executed in SSH?

• Options to efficiently synchronize 1 million files with remote servers?

  - by Zilvinas

  At a company I work for we have such a thing called "playlists" which are small files ~100-300 bytes each. There's about a million of them. About 100,000 of them get changed every hour. These playlists need to be uploaded to 10 other remote servers on different continents every hour and it needs to happen quick in under 2 mins ideally. It's very important that files that are deleted on the master are also deleted on all the replicas. We currently use Linux for our infrastructure. I was thinking about trying rsync with the -W option to copy whole files without comparing contents. I haven't tried it yet but maybe people who have more experience with rsync could tell me if it's a viable option? What other options are worth considering?

• How can I tell what command is running on the remote end of an ssh connection?

  - by user268385

  Tl;dr - how do I find the name of the command (eg $BASH_COMMAND) running on the remote end of an ssh connection? ... My example setup is two tmux vertical panes, LH pane runs a local vim session with vertical split, RH pane runs an ssh session running vim, again with a vertical split. Using tmux-navigator I can navigate from left to right over the first 3 vim buffers, but the 4th (far right hand one) is inaccessible. The reason for this is that tmux-navigator tests the value of 'pane_current_command' and compares it to 'vim' before deciding which keystrokes to dispatch. On the right hand tmux pane, the current command is 'ssh' and not 'vim'. What I want to do is test for (pane_current_command =~ 'ssh'), and if so, examine the command that is running on the far side of the connection? I cannot find a way to get hold of this, so any suggestions would be welcome? For information, the problem is almost the same as this one, but without the nested tmux sessions: https://github.com/christoomey/vim-tmux-navigator/issues/12

• Can Remote Desktop connect only 2 monitors when the client has 3 or 4 monitors connected?

  - by user12931

  I have three monitors (all 1920x1200) connected to my desktop and I would like to RDP into another computer (running Windows Server 2003) and use only two of my three monitors. The main monitor is used for notification from the LAN like email, build status, etc. I've tried modifying the .rdp file to have a higher resolution (i.e. 3840x1200 ) which sort of works but the bits per pixel goes down to 8 and you have to manually resize the window which means that you need to change it to around 3840x1150. If I supply /span to the commandline it gives me a bit more than 3840 spanned across the three monitors (is there perhaps a limitation of say 4096 for the maximum resolution?). WORKAROUND: Connect twice to the same computer. Here's an interesting post from Microsoft: http://blogs.msdn.com/b/rds/archive/2009/08/21/remote-desktop-connection-7-for-windows-7-windows-xp-windows-vista.aspx

• How do I run perfmon against a remote machine?

  - by WindyCityEagle

  For starters I'm trying to do this from a Windows 7 box to a Windows 7 box. I know the simple answer should be to enter \\computername where it says "Select Counters From Computer". Trouble is, every time I do that I get an error message that says "Unable to connect to machine" I know the machine is out there and accessible, because I can bring up windows explorer and enter \\computername\c$ in the explorer bar and then can browse their c drive. So the machine is out there. Are there special permissions for perfmon? Is here a service which needs to be running on the remote machine?

• Automated monitoring of a remote system that sends email alerts.

  - by user23105

  I need to monitor a remote system where the only access I have is that I can subscribe to email alerts of completed/failed jobs. I would like a system that can monitor these emails and provide an SMS or other alert when: An email indicates failure. A process that was expected to complete by a given time has not. A process that was expected to complete N minutes after completion of another process has not completed. Are there any existing tools that allow this? I'd consider any option - SaaS, open-source, COTS, as long as I don't have to write it myself! Cheers, Blake

• strange memory usage pattern on windows server 2008 on login through remote desktop..

  - by headsling

  I'm running Windows Server 2008 Datacenter Service Pack 2 on a VM Ware instance with 10Gb ram allocated. I'm not running IIS or SQL Server. Under 'normal' conditions, the machine uses ~5.5Gb of memory. However, when I login to the server through remote desktop, the memory usage slowly climbs up to 9.8Gb of memory in use. After several minutes the memory slowly creeps back down to the 5.5Gb mark. I've tried killing all the processes associated with my login, on login, barring the taskmanager without success, and I can't see any process that is growing in memory usage when the memory is increasing. I'm assuming this is some system level cache that is growing / shrinking... but why is it doing this?

• NDepend tool – Why every developer working with Visual Studio.NET must try it!

  - by hajan

  In the past two months, I have had a chance to test the capabilities and features of the amazing NDepend tool designed to help you make your .NET code better, more beautiful and achieve high code quality. In other words, this tool will definitely help you harmonize your code. I mean, you’ve probably heard about Chaos Theory. Experienced developers and architects are already advocates of the programming chaos that happens when working with complex project architecture, the matrix of relationships between objects which simply even if you are the one who have written all that code, you know how hard is to visualize everything what does the code do. When the application get more and more complex, you will start missing a lot of details in your code… NDepend will help you visualize all the details on a clever way that will help you make smart moves to make your code better. The NDepend tool supports many features, such as: Code Query Language – which will help you write custom rules and query your own code! Imagine, you want to find all your methods which have more than 100 lines of code :)! That’s something simple! However, I will dig much deeper in one of my next blogs which I’m going to dedicate to the NDepend’s CQL (Code Query Language) Architecture Visualization – You are an architect and want to visualize your application’s architecture? I’m thinking how many architects will be really surprised from their architectures since NDepend shows your whole architecture showing each piece of it. NDepend will show you how your code is structured. It shows the architecture in graphs, but if you have very complex architecture, you can see it in Dependency Matrix which is more suited to display large architecture Code Metrics – Using NDepend’s panel, you can see the code base according to Code Metrics. You can do some additional filtering, like selecting the top code elements ordered by their current code metric value. You can use the CQL language for this purpose too. Smart Search – NDepend has great searching ability, which is again based on the CQL (Code Query Language). However, you have some options to search using dropdown lists and text boxes and it will generate the appropriate CQL code on fly. Moreover, you can modify the CQL code if you want it to fit some more advanced searching tasks. Compare Builds and Code Difference – NDepend will also help you compare previous versions of your code with the current one at one of the most clever ways I’ve seen till now. Create Custom Rules – using CQL you can create custom rules and let NDepend warn you on each build if you break a rule Reporting – NDepend can automatically generate reports with detailed stats, graph representation, dependency matrixes and some additional advanced reporting features that will simply explain you everything related to your application’s code, architecture and what you’ve done. And that’s not all. As I’ve seen, there are many other features that NDepend supports. I will dig more in the upcoming days and will blog more about it. The team who built the NDepend have also created good documentation, which you can find on the NDepend website. On their website, you can also find some good videos that will help you get started quite fast. It’s easy to install and what is very important it is fully integrated with Visual Studio. To get you started, you can watch the following Getting Started Online Demo and Tutorial with explanations and screenshots. If you are interested to know more about how to use the features of this tool, either visit their website or wait for my next blogs where I will show some real examples of using the tool and how it helps make your code better. And the last thing for this blog, I would like to copy one sentence from the NDepend’s home page which says: ‘Hence the software design becomes concrete, code reviews are effective, large refactoring are easy and evolution is mastered.’ Website: www.ndepend.com Getting Started: http://www.ndepend.com/GettingStarted.aspx Features: http://www.ndepend.com/Features.aspx Download: http://www.ndepend.com/NDependDownload.aspx Hope you like it! Please do let me know your feedback by providing comments to my blog post. Kind Regards, Hajan

• How do I get a Dane-Elec mp3/mp4 player working?

  - by user40432

  My MP3/MP4 does not plug-in and play and therefore I can not transfer any file to the MP3/MP4 dane-elec music my touch or only dane-elec with 8 gb in memory and perhapses model zt1 with radio,..and microsdhc card slot following the above link the mp3/mp4 is there and it is MP3 Player: TOUCH MY MUSIC and the complete information is on this site http://www.danedigital.com/8-Music-Media-Players/2-music-touch.html as the Technical Specifications MP3 Player: TOUCH MY MUSIC The Mp4 player has a very classy. It allows its users to play music and view photos and video. His fluent interface, its touch-pad, his radio and RDS Micro SDHC reader makes him a very complete device will become the ideal musical companion. ubuntu i am with is ubuntu 11.10 kernel 3.0.0-14-generic the latest I tried to install many applications but nothing worked. With disk utility I can see that Ubuntu can recognize something, that as a peripheral device named rockchip usbdisk user and rockchip usbdisk sd, and i can plug and play other devices, and only this mp3/mp4 do not connect to the computer with ubuntu and the device as no problem working disconnected to computer I try to see if work on Windows and it does! I can see the device and transfer files to the MP3/MP4 dane-elec folder device and use FAT32. So why can not do on Ubuntu!? What can I do and why does not work on Ubuntu? What is wrong with it?

• Randomly placing items script not working - sometimes items spawn in walls, sometimes items spawn in weird locations

  - by Timothy Williams

  I'm trying to figure out a way to randomly spawn items throughout my level, however I need to make sure they won't spawn inside another object (walls, etc.) Here's the code I'm currently using, it's based on the Physics.CheckSphere(); function. This runs OnLevelWasLoaded(); It spawns the items perfectly fine, but sometimes items spawn partway in walls. And sometimes items will spawn outside of the SpawnBox range (no clue why it does that.) //This is what randomly generates all the items. void SpawnItems () { if (Application.loadedLevelName == "Menu" || Application.loadedLevelName == "End Demo") return; //The bottom corner of the box we want to spawn items in. Vector3 spawnBoxBot = Vector3.zero; //Top corner. Vector3 spawnBoxTop = Vector3.zero; //If we're in the dungeon, set the box to the dungeon box and tell the items we want to spawn. if (Application.loadedLevelName == "dungeonScene") { spawnBoxBot = new Vector3 (8.857f, 0, 9.06f); spawnBoxTop = new Vector3 (-27.98f, 2.4f, -15); itemSpawn = dungeonSpawn; } //Spawn all the items. for (i = 0; i != itemSpawn.Length; i ++) { spawnedItem = null; //Zeroes out our random location Vector3 randomLocation = Vector3.zero; //Gets the meshfilter of the item we'll be spawning MeshFilter mf = itemSpawn[i].GetComponent<MeshFilter>(); //Gets it's bounds (see how big it is) Bounds bounds = mf.sharedMesh.bounds; //Get it's radius float maxRadius = new Vector3 (bounds.extents.x + 10f, bounds.extents.y + 10f, bounds.extents.z + 10f).magnitude * 5f; //Set which layer is the no walls layer var NoWallsLayer = 1 << LayerMask.NameToLayer("NoWallsLayer"); //Use that layer as your layermask. LayerMask layerMask = ~(1 << NoWallsLayer); //If we're in the dungeon, certain items need to spawn on certain halves. if (Application.loadedLevelName == "dungeonScene") { if (itemSpawn[i].name == "key2" || itemSpawn[i].name == "teddyBearLW" || itemSpawn[i].name == "teddyBearLW_Admiration" || itemSpawn[i].name == "radio") randomLocation = new Vector3(Random.Range(spawnBoxBot.x, -26.96f), Random.Range(spawnBoxBot.y, spawnBoxTop.y), Random.Range(spawnBoxBot.z, -2.141f)); else randomLocation = new Vector3(Random.Range(spawnBoxBot.x, spawnBoxTop.x), Random.Range(spawnBoxBot.y, spawnBoxTop.y), Random.Range(-2.374f, spawnBoxTop.z)); } //Otherwise just spawn them in the box. else randomLocation = new Vector3(Random.Range(spawnBoxBot.x, spawnBoxTop.x), Random.Range(spawnBoxBot.y, spawnBoxTop.y), Random.Range(spawnBoxBot.z, spawnBoxTop.z)); //This is what actually spawns the item. It checks to see if the spot where we want to instantiate it is clear, and if so it instatiates it. Otherwise we have to repeat the whole process again. if (Physics.CheckSphere(randomLocation, maxRadius, layerMask)) spawnedItem = Instantiate(itemSpawn[i], randomLocation, Random.rotation); else i --; //If we spawned something, set it's name to what it's supposed to be. Removes the (clone) addon. if (spawnedItem != null) spawnedItem.name = itemSpawn[i].name; } } What I'm asking for is if you know what's going wrong with this code that it would spawn stuff in walls. Or, if you could provide me with links/code/ideas of a better way to check if an item will spawn in a wall (some other function than Physics.CheckSphere). I've been working on this for a long time, and nothing I try seems to work. Any help is appreciated.

• Github file size limit changed 6/18/13. Can't push now

  - by slindsey3000

  How does this change as of June 18, 2013 affect my existing repository with a file that exceeds that limit? I last pushed 2 months ago with a large file. I have a large file that I have removed locally but I can not push anything now. I get a "remote error" ... remote: error: File cron_log.log is 126.91 MB; this exceeds GitHub's file size limit of 100 MB I added the file to .gitignore after original push... But it still exists on remote (origin) Removing it locally should get rid of it at origin(Github) right? ... but ... it is not letting me push because there is a file on Github that exceeds the limit... https://github.com/blog/1533-new-file-size-limits These are the commands I issued plus error messages.. git add . git commit -m "delete cron_log.log" git push origin master remote: Error code: 40bef1f6653fd2410fb2ab40242bc879 remote: warning: Error GH413: Large files detected. remote: warning: See http://git.io/iEPt8g for more information. remote: error: File cron_log.log is 141.41 MB; this exceeds GitHub's file size limit of 100 MB remote: error: File cron_log.log is 126.91 MB; this exceeds GitHub's file size limit of 100 MB To https://github.com/slinds(omited_here)/linexxxx(omited_here).git !

• I have a problem with a AE1200 Cisco/Linksys Wireless-N USB adapter having stopped working after I ran the update manager in Ubuntu 12.04

  - by user69670

  Here is the problem, I use a Cisco/Linksys AE1200 wireless network adapter to connect my desktop to a public wifi internet connection. I use ndiswrapper to use the windows driver and it had been working fine for me untill I ran the update manager overnight a few days ago. When I woke up it was asking for the normal computer restart to implement the changes but after rebooting the computer, the wireless adapter did not work, the status light on the adapter did not light up even though ubuntu recognizes it is there and according to ndiswrapper the drivers are loaded and the hardware is present. the grep command is being a bitch for some unknown reason today so this will be long sorry Output from "lspci": 00:00.0 Host bridge: Advanced Micro Devices [AMD] nee ATI Radeon Xpress 200 Host Bridge (rev 01) 00:01.0 PCI bridge: Advanced Micro Devices [AMD] nee ATI RS480 PCI Bridge 00:12.0 SATA controller: Advanced Micro Devices [AMD] nee ATI SB600 Non-Raid-5 SATA 00:13.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI0) 00:13.1 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI1) 00:13.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI2) 00:13.3 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI3) 00:13.4 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI4) 00:13.5 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB Controller (EHCI) 00:14.0 SMBus: Advanced Micro Devices [AMD] nee ATI SBx00 SMBus Controller (rev 13) 00:14.1 IDE interface: Advanced Micro Devices [AMD] nee ATI SB600 IDE 00:14.3 ISA bridge: Advanced Micro Devices [AMD] nee ATI SB600 PCI to LPC Bridge 00:14.4 PCI bridge: Advanced Micro Devices [AMD] nee ATI SBx00 PCI to PCI Bridge 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RC410 [Radeon Xpress 200] 02:02.0 Communication controller: Conexant Systems, Inc.

• How best do you represent a bi-directional sync in a REST api?

  - by Edward M Smith

  Assuming a system where there's a Web Application with a resource, and a reference to a remote application with another similar resource, how do you represent a bi-directional sync action which synchronizes the 'local' resource with the 'remote' resource? Example: I have an API that represents a todo list. GET/POST/PUT/DELETE /todos/, etc. That API can reference remote TODO services. GET/POST/PUT/DELETE /todo_services/, etc. I can manipulate todos from the remote service through my API as a proxy via GET/POST/PUT/DELETE /todo_services/abc123/, etc. I want the ability to do a bi-directional sync between a local set of todos and the remote set of TODOS. In a rpc sort of way, one could do POST /todo_services/abc123/sync/ But, in the "verbs are bad" idea, is there a better way to represent this action?

• Site-to-site VPN using MD5 instead of SHA and getting regular disconnection

  - by Steven

  We are experiencing some strange behavior with a site-to-site IPsec VPN that goes down about every week for 30 minutes (Iam told 30 minutes exactly). I don't have access to the logs, so it's difficult to troubleshoot. What is also strange is that the two VPN devices are set to use SHA hash algorithm but apparently end up agreeing to use MD5. Does anybody have a clue? or is this just insufficient information? Edit: Here is an extract of the log of one of the two VPN devices, which is a Cisco 3000 series VPN concentrator. 27981 03/08/2010 10:02:16.290 SEV=4 IKE/41 RPT=16120 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 27983 03/08/2010 10:02:56.930 SEV=4 IKE/41 RPT=16121 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 27986 03/08/2010 10:03:35.370 SEV=4 IKE/41 RPT=16122 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) [… same continues for another 15 minutes …] 28093 03/08/2010 10:19:46.710 SEV=4 IKE/41 RPT=16140 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 28096 03/08/2010 10:20:17.720 SEV=5 IKE/172 RPT=1291 xxxxxxxx Group [xxxxxxxx] Automatic NAT Detection Status: Remote end is NOT behind a NAT device This end IS behind a NAT device 28100 03/08/2010 10:20:17.820 SEV=3 IKE/134 RPT=79 xxxxxxxx Group [xxxxxxxx] Mismatch: Configured LAN-to-LAN proposal differs from negotiated proposal.

• using x11 forwarding with ssh and vnc?

  - by simona

  I am working on a remote cluster via ssh with the -X option, because I need to visualize data and graphs, over a vpn protocol. Sometime due to the instability of the internet connection I lose my session. They told me I could use vnc in order to not lose my current session, so that if the internet connection drops I can reconnect and continue with my previously open session. What I do is to log in the remote cluster 'remote.cluster' and type vncserver :1 then I open another terminal on my system and I type ssh -C -NL 5901:remote.cluster:5901 [email protected] & Then I start vinagre on my system and I connect using ssh protocol. The problem is that I do not have x11 forwarding and I cannot open windows. If I try to connect using the vnc protocol with vinagre it doesn't connect, because I get something as connection timeout. What should I do?

• IIS 7.5 fails to open database after computer machine on that database server is working restarts.

  - by Jenea

  Hi. I decided to post this question also here in case the issues we have is related to sql server. There is a problem that bother me for some time. I have an asp.net mvc that uses NHibernate for modeling the database. The infrastructure is the following: Windows 2008 R2 for all virtual machines. IIS 7.5 is working on one virtual machine. Sql Server 2008 is working on another virtual machine. We have couple of databases, two that stores application data and one that registers all unhandled exceptions. Sometimes virtual machine that hosts database server restarts (in the middle of the night, not quite sure about the reason) after that connection to the databases that stores application data is not working and as result there are thousands of unhandled exceptions that get registered in the third database. Important to mention that databases are accessible from Management Studio. The problem is solved by resetting IIS. Connetion are handled via NHibernateUtil class which opens and closes session at each request.

• OS X (10.6) Apache Sudden Death, Nginx not working either...

  - by Jesse Stuart

  Hi, I turned on my computer today and apache wasn't working. This is weird as its been working for the last 6 months without issue. The only thing I did which may of caused a problem, is I uninstalled a bunch of gems. This shouldn't be the issue though as apache doesn't rely on gems. I decided to give nginx a try to see if it would work and have the exact same issue. The symtoms are: I go to http://localhost and get the browsers default 404 page (not rendered by apache/nginx) No error is found anywhere (I checked all logs) Apache is rinning (also tried with Nginx) How can I debug this to find the root of the problem? I can't think of why this would be happening. I've tried repairing permissions in case this was the issue, apparently it wasn't. Everything was working the other day, and nothing changed in the apache config. Update: Here is the output of telnet localhost 80 $ telnet localhost 80 Trying ::1... telnet: connect to address ::1: Connection refused Trying fe80::1... telnet: connect to address fe80::1: Connection refused Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host

• How do I allow remote access to mysql using xampp?

  - by sprugman

  I'm using xampp and navicat to manage mysql on two dev machines (laptop & desktop). The laptop is my main machine, while the desktop acts as a local dev server for the group. Connecting to mysql via localhost in navicat is working fine on the laptop. Is there a way (other than the http tunneling method) to allow access to the desktop from the laptop via navicat?

• Web Interfaces not opening even after Port Forwarding is said to be working!

  - by Ahmad

  I'm encountering this strange problem which has baffled me to the ground, and which I haven't encountered even after years of doing port forwarding .. ! I am hoping somebody here can help me solve this mystery .. :) My network configuration is as follows: I have a DSL modem (custom made and branded by my ISP) which is receiving a DSL stream ... it has an external IP which is visible to the world, say, 11.22.33.44 ... This modem has DHCP enabled, has an internal IP for itself, which is 192.168.1.1 .. it is connected to 2 laptops via and ethernet cable .. Laptop 1 has IP 192.168.1.2, and Laptop 2 has IP 192.168.1.3 ... On Laptop 1, two applications are running, jDownloader and Media Player Classic, which have their web interfaces on ports 8765 and 13579, respectively ... I can access both of these web interfaces from Laptop 2 by opening these addresses: 192.1681.2:8765 and 192.168.1.2:13579 ... both of their web interfaces open up, meaning the web interfaces are working fine .. Moving on, I now want to access these web interfaces from outside my network as well, and so I've configured port forwarding in my PTCL modem to forward all traffic on ports between 8000 and 14000 (both TCP and UDP) to IP 192.168.1.2 ... I have verified that port forwarding is working by testing it using PortForward.com's port checker tool, and this website too: [URL]http://www.yougetsignal.com/tools/open-ports/[/URL] When I use the website, if I'm running the applications on Laptop 2, the website reports that the port is open .. if I then close the application, the website reports the port is closed ... This makes sense as nothing is listening on my machine in the latter case .. Also, if I disable port forwarding in my modem, again, the website reports the port is closed ... so, the website's results seem to be okay ... Same of the above can be said when I'm used PortForward.com's port checker tool ... So again, everything okay so far ... Now, here comes the problem !! ... Despite the above tools reporting that port forwarding is working, I am unable to open the web interfaces from outside my network ... So for example, if I tried to browse 11.22.33.44:8765 or 11.22.33.44:13579, nothing opens in my browser ... But if I accessed these web server's locally from Laptop 3, by typing in 192.168.1.2:8765 or 192.168.1.2:13579, they opened ... So where is the problem here ?? The tools report unanimously that port forwarding is working, and yet I am unable to open the web interfaces from outside the network .. Also note that I have disabled the firewall from my computer, and have also made sure that any option in the above programs (whose web interfaces I am trying to open) that says only local connections are to be accepted, is disabled ... So whats the problem ... ?!! Any ideas ??

• Under which circumstances can a *local* user account access a remote SQL Server with a trusted connection?

  - by Heinzi

  One of our customers has the following configuration: On the domain controller, there's an SQL Server. On his PC (WinXP), he logs on with LocalPC\LocalUser. In Windows Explorer, he opens DomainController\SomeShare and authenticates as Domain\Administrator. He starts our application, which opens a trusted connection (Windows authentication) to the SQL Server. It works. In SSMS, the connection shows up with the user Domain\Administrator. Firstly, I was surprised that this even works. (My first suspicion was that there is a user with the same name and password in the domain, but there is no user LocalUser in the domain.) Then we tried to reproduce the same behaviour on his new PC, but failed: On his new PC (Win7), he logs on with OtherLocalPC\OtherLocalUser. In Windows Explorer, he opens DomainController\SomeShare and authenticates as Domain\Administrator. He starts our application, which opens a trusted connection (Windows authentication) to the SQL Server. It fails with the error message Login failed for user ''. The user is not associated with a trusted SQL Server connection. Hence my question: Under which conditions can a non-domain user access a remote SQL Server using Windows Authentication with different credentials? Apparently, it's possible (it works on his old PC), but why? And how can I reproduce it?
