• Getting started with VNC

  - by Stephen

  I have subscribed to a VPS service for the purpose of running some remote applications. To do this I'm going to need a remote desktop of one sort or another. With this in mind it was suggested that I try Ubuntu. The installation that was prepared for me was Ubuntu 11.10 64 bit (Ubuntu 11.10 (GNU/Linux 2.6.18-348.4.1.el5.028stab107.1 x86_64)) From here I used apt-get install ubuntu-desktop which completed successfully. I rebooted the machine and reconnected via ssh. When I attempt to connect from TightVNC on my Windows machine I get a message about the session being actively refused. What should I do to confirm the service is running? Do I need to setup a firewall rule to allow the ports to pass through? (I am a linux newb so explicitness is appreciated)

• Can the Windows 8 Live SDK use another Microsoft Account other than the current user?

  - by Jerry Nixon

  Using the Windows 8 Live SDK you can have a user give you permission to their Microsoft Account. With this you can get their name and photo and more. But using the Live SDK appears to require the user of the app to use the same Microsoft Account as whoever is signed into the current session of Windows 8. In some scenarios, using a different account is very legitimate. I have simple sign-in working like a charm! This uses the same account. I can't find a way to do use another. Is it possible?

• Windows Desktop Randomly Switches Resolution

  - by bobber205

  Once per log in a specific account, Windows XP is switching to 800x600 and 8 (looks like) bit color. It then after a few seconds switches back to the regular settings. This, so far, has only happened, once per log in session but it is becoming very annoying for the end user. :P Any ideas? I've tried turning off hardware acceleration as well as getting rid of her picture desktop wallpaper but nothing has made a difference. Thanks for any help!

• Wyse Simple Imager. Unable to Create Product Directory

  - by Steve

  I am trying to submit a post on www.technicalhelp.de, but I receive an error: Invalid Session. Please resubmit the form. This happens if I delete temporary internet files and log out and back in, and if I use a different browser, and if I use a proxy browser. Perhaps someone on this forum can help I am trying to push a Wyse device image to a USB thumb drive. The image is on a remote server, and the thumb drive is connected to my desktop PC. I am using Wyse Simple Imager to do this. When I select the following: Product: V90 Image Version: 5.010627.512 Image File: \servername\folder\OLD_Rapport\V90-withusb\9V90.i2d Almost instantly, without attempting any action, I receive the message: WyseImager Unable to Create Product Directory. Add Image Failed I have completely formatted the USB drive with FAT32. It is new out of the fox, and I can create folders in it. How do I fix this?

• Determine $DISPLAY socket name on OS X 10.6?

  - by Nate

  I'm looking to do something that's a little odd. I'm SSH'ing from a server to a Snow Leopard client to start an X11 data display process. In other words, SSH's X11 forwarding isn't what I want. I can do: client$ echo $DISPLAY /tmp/launch-SOMETHING/org.x:0 client$ ls -l $DISPLAY srwx------ 1 myuser wheel 0 Dec 9 15:47 /tmp/launch-SOMETHING/org.x:0 And, when I do: server$ ssh myuser@client client$ export DISPLAY=/tmp/launch-SOMETHING/org.x:0 client$ xterm I happily get my xterm. What I need, then, is some way to find out the correct value for $DISPLAY in my ssh session. From what I've read, $DISPLAY is set by launchd, but I haven't found any way to see that value. If it matters, I know that when my process connects from $server to $client, $client will logged in to the terminal as the same user.

• Log highlighted lines to window in irssi

  - by Sebastian P.

  I usually keep an irssi session running on my server at all times. Often times it also takes me quite a while between remembering that I in fact have it running. Therefore I'd like to know if there's an easy way to log all lines that are highlighted to a custom window, such that I later, when I return, can see what people have said that was directed at me. Most useful would of course be if it logged both nickname, time and place (channel, network) of the message. I've been looking around, and haven't managed to get anything working which accomplishes this, so it would be splendid if such a thing existed.

• phpMyAdmin logs out when selecting database

  - by deed02392

  I'm having an issue with pma whereby after logging in (as root or the database owner), and trying to switch to a certain database, I am automatically logged out. I cannot do any actions on the database and in the page that loads immediately before I'm logged out I note that I can't see any tables in the database. The database is accessible by the cli mysql program and all records are still present. To clarify: Literally login works fine, I can browse ALL databases except the one of my projects. Trying to use that database causes the phpMyAdmin session to end. Thanks!

• How to manage large number of desktop VMs?

  - by symcbean

  I'm looking at the feasibility of providing remote access to multiple virtual machines. The VMs themselves will provide user desktops. To make best use of the available resources, I'd like the VMs to hibernate when the user disconnects. Which implies being able to start them up when a user connects. Ideally each user would 'own' a VM image - but if not then I'd require that the session was terminated. Obviously this would require the remote access protocol to be tied into the VM management. Is there anything out there to provide such functionality? (extra credit for open protocols! ;)

• How to log Windows server share connections?

  - by sbussinger

  Can anyone make a suggestion for the best way to log connections and disconnections from Windows workstations to a Windows Server 2003 file share? We're having some issues with workstations that have a drive mapped to a server that seem to work fine for awhile and then suddenly appear to get disconnected from the server (with files open). Needless to say this causes some data corruption and error messages. It would help me to troubleshoot the problem if we could somehow monitor and log the session connections and disconnections, to attempt to correlate the connectivity issues with what actions the user is taking at the time and what the server is doing. I just haven't been able to find a way to do this. Specifically I'm talking about the same information that is displayed in the Computer Management control panel applet in the "System Tools|Shared Folders|Sessions" page. Thanks!

• Windows 8 / Server 2012 RDP connection is slow

  - by Chris

  I recently installed Windows Server 2012 for development purposes at our office and noticed immediately that connecting via RDP is slow. It can take 5-10 seconds to connect at times, where as connecting to any of our Win7 or Win2008R2 boxes takes at most 1-3 seconds. At first, I chalked this up to the box itself needing a driver update or something, but just yesterday, I installed Win8 on my desk PC and connecting from home to that machine produces the same result. There is a 3-4 second pause at "securing remote connection" and then again at "configuring remote session". I don't see any warnings in the event log, and once connected, there do not appear to be any performance issues. Is there a known problem with RDP connections on Windows 8 systems? Anything I should look for?

• How to "eject" non-existing USB drive from Windows 7 host?

  - by gencha

  I use a USB key which is encrypted with BitLocker to store various data. I keep that key with me all the time. What happens all the time is that I send my home computer to hibernate without ejecting the USB key first. Then I unplug the key and take it with me to work. When I get home, I resume my Windows session and even though the key is not plugged in, the drive still appears as mounted on the system. I can also unmount the non-existing device with mountvol, but that only removes the drive letter. Windows will still think the device is plugged in. When I plug the key in, nothing happens. The device's class ID is listed in mountvol output, but the device is not listed in the Disk Management panel.

• Fixing copy/paste for Remote Desktop Connection sessions [duplicate]

  - by netadictos

  Possible Duplicate: Can't copy and paste in Remote Desktop Connection session Recently I have been working with Remote Desktop Connection. I use it to access a virtual machine implemented through Hyper-V. I have had many problems with the simple operation of cut-and-paste from my machine to the virtual one. The link between my clipboard and the remote clipboard is often broken. It is usual that this happens, when I copy/cut in the remote machine and then copy in my computer and then paste in the remote machine, How do I fix this?

• How to setup a simple Ubuntu Server Tomcat cluster on VirtualBox for testing?

  - by Alex Pakka

  I am looking for a step by step instructions to setup at leat two (and later more) simple Ubuntu Virtual Core 12.10 Server VMs on Oracle VirtualBox under Windows 7 64bit. The test setup would be: Apache HTTP server on the Windows host acting as a Load Balancer. The result will be that going to http://localhost:8080 would balance between two nodes and prove session replication. Two lean, small footprint Ubuntu Server guest nodes with Java 7 and Tomcat 7. The intention is to help everyone doing High Availability / Load Balancing development and testing to create a reasonable environment on the local workstation or mainstream notebook in as little time as possible.

• Terminal, vim and ssh color problem

  - by xaph

  I'm using vim for my editor. I've problems about the colors of vim. The same colorscheme of vim gives different outputs in terminal, ssh session and screen. I learnt they've different colors(16, 88 or 256). I don't care of using 16 color or 256 color. Also the terminal emulator is not very important to me. My questions: 1- How do I use same vim colorscheme with same output on everywhere? 2- I want to write a color definition and use it every terminal(maybe with Xdefaults file). Is it possible?

• How to set the laptop screen brightness programatically?

  - by zls

  I'm currently migrating to openbox without gnome session. In unity i can use the vendor keys to set the screen brightness, but in openbox I'm on my own. /sys/class/backlight/acpi_video0/brightness works fine, the problem is that I need sudo to set the brightness and that wouldn't work with keyboard mappings. xbacklight -get/set doesn't do or output anything. I don't really want to use xrandr --brightness. Are there any other options or a way to fix the problems with xbacklight or acpi_video0 ?

• XDMCP is slow any ideas? (looking for alternative remote desktops)

  - by peteri

  I've been used to using RDP on Windows to remote to machines, and I've got an asus eee 701 which I want to use to do some *nix programming on. While the eee is a lovely little machine the screen and keyboard are a little small to use for lots of programming. I've tried using Xming (the free version) to remote login into the eee from my desktop using XDMCP (or even using a ssh session as a straight X11 server and no desktop on the eee) the whole thing seems seriously slow over wifi the initial desktop takes at least 5 seconds to paint (might even be 10 seconds I haven't actually timed it). So my real question is what do other folks use for remote control with a GUI for their *nix boxes? I am finding it hard to believe the performance is so bad over a wifi network (It makes the Mac IIs I used to use a college in 1988 seem fast) or is this just a problem with Xming and using say the Cygwin X11 server would be better.

• How do I restore the Gnome Panel volume control in Ubuntu 10.04?

  - by Neil

  I use alsa, and I don't have a volume control applet on my Gnome Panel. When I right click and select "add to panel", there is nothing that has to do with "sound", "audio" or "volume" in the list, and the "Indicator Applet" or "Indicator Applet Session" things have no volume controls, or properties that would let you enable any sort of volume control. How can I get a volume control in Ubuntu, so I don't have to run aumix in a terminal or something? I've been using Linux since Redhat 5, it's beyond me why these sorts of problems are still around. Someone should just put a damn "Volume Control" element in the list of things to add to the panel, even if it doesn't work, perhaps showing an error message.

• ADFS http login failure not re-requesting credentials

  - by Devnull

  We have ADFS working with HTTP (401) login. If a user types their password incorrectly, ADFS barfs and requires that the browser be closed, rather than asking the user for to attempt to log in again. Reprompting for user credentials is the typical behavior with other web servers (even IIS). This appears to be an artifact of setting the HTTP session, but other HTTP-login applications dont behave this way. We are having additional issues now because some users are saving that password, and its causing them account lockouts because the browsers do not realize they need to update saved credentials. Anyone know of a workaround? Wed rather not enable forms login if possible.

• Virtualise Excel in a browser

  - by Macros

  Is it possible to give users access to a virtualised instance of Excel - I don't want to give them access to a full OS (although this will clearly be running in the background, all they can access is Excel - they don't even see any other screens)? Secondly, if it is possible, is it possible to do within a browser? Edit I am building a system which is designed to test candidates skills in Excel and for this reason needs to use the full desktop version and not a web app. I don't want to have to ensure Excel is installed on the client machine as there will be issues around differing versions and security as the workbook(s) that are used in the test use VBA extensively to customise and mark the exercises. Ideally my web app would be able to open a session to the server which then just puts the user into an instance of Excel without ever seeing a desktop. I would also need to be able to pass in command line parameters in order to define which workbook to open and also pass in a unique token to identify the user

• reverse-proxy web access on a server where only SSH is allowed

  - by Kaii

  Every once in a while i have to connect to a server where access is highly restricted. Only inbound SSH is allowed by the DMZ firewall - outbound HTTP connections are blocked. I'm looking for a good way to tunnel web access through my SSH session, so i can install updates and software via yum / apt-get. What do you do in such a situation? SSH has the -D <port> SOCKS proxy option. But unfortunately it is one-way only from client to server and there is no reverse option.

• How do I get rid of the Cisco CP one-time user message on a Cisco 2901 router?

  - by user65712

  I get this message on a new 2901 Cisco router: Cisco Configuration Professional (Cisco CP) is installed on this device and it provides the default username "cisco" for one-time use. If you have already used the username "cisco" to login to the router and your IOS image supports the "one-time" user option, then this username has already expired. You will not be able to login to the router with this username after you exit this session. It is strongly suggested that you create a new username with a privilege level of 15 using the following command. username <myuser> privilege 15 secret 0 <mypassword> Replace and with the username and password you want to use. It appears every time I login and everytime I show run. I already set up my username. How do I turn it off?

• How do I permanently disable Linux's console screen saver, system-wide?

  - by raldi

  I've got an Ubuntu server that boots up in text mode. It rarely has a screen or keyboard attached to it, but when I do attach a screen, I usually have to attach a keyboard too, because the darn console mode screen saver will be on and I'll need to hit a key to see what's going on. I'm aware that the setterm command can disable this, but it's a per-session thing. How can I make it so the machine never ever blanks the screen in text mode, even when it's first booted up and sitting at the login prompt?

• Manage a lot of open ssh sessions to servers with id's for hostname

  - by kimausloos

  Lately I'm working a lot with a few open ssh connections to multiple VPS servers. The hostnames of the servers all follow an ID approach and it's becoming very difficult to know on what machine I'm working with. I was wondering if there is a way to put a name I define somewhere as the title of the terminal. So I would, for example, associate IP 123.123.123.123 with webserver-stg. When opening the connection to the IP, webserver-stg would automaticaly be displayed as the name of the session. Of course I'm not able to change code on the VPS servers, so the solution should be client-side.

• Cannot login as root to centos server

  - by perpetual_dream

  I used to login as :ssh root@servip with a password authentication into my centos 6 server. I am not sure if what I have done has caused this, but while trying to get over my problem of accessing webmin remotely I followed the following tutorial until I reached: adding auth required pam_google_authenticator.so into /etc/pam.d/sshd. Then by mistake, I have closed the ssh session. When I tried to login in back with the usual password, I get: Permission denied, please try again error. How can I get over this problem? I don't have a physical access to the server.

• Disable RDC Welcome Screen in Windows 2008 R2

  - by mikebridge

  Is there a way to disable or bypass the "Welcome" screen I see when I'm using RDC to log in to a machine using saved credentials? I have startup task which launches an RDP session automatically to localhost when the machine boots. This works, except that the remote desktop window stops and waits for an "OK" on the Welcome screen: MACHINENAME-A.B.C.D(Server ID:Console 0) Welcome [OK] This screen is preventing me from automating this login. Is there any way to get around it? EDIT: Here's the command line I'm currently using to launch it: start /min C:\windows\system32\mstsc.exe c:\rdp\ServiceRunner.rdp
