• Forwarding port 3306 on Mac OS X in order to connect to a remote MySQL Database

  - by Jonathan Mayhak

  I'm on Mac OS X 10.6.2 trying to connect to ubuntu server 8.04.1 at linode. ssh -L 127.0.0.1:3306:[[remote ip]]:3306 user@server -N I want to set up ssh tunneling so that I can access a remote mysql server. First of all, I'm told bind: Address already in use. This is only after I've tried the command before. How do I manually close a port forwarding session? Second, when I change the command to be ssh -L 127.0.0.1:3310:[[remote ip]]:3306 user@server -N (I changed the local port to listen on). I'm told channel 1: open failed: connect failed: Connection refused when I try to connect to the MySQL server via MySQL workbench or sequel pro. To connect through MySQL workbench I use the following settings: host: 127.0.0.1 port: 3310 (if 3306 is in use) username: mysql username password: mysql password database: I don't put anything in

• Windows 7: Open File - Security Warning box appears for every app on the desktop

  - by Michael Ratanapintha

  Whenever I double-click to open an executable on the desktop (.exe, .bat, etc.), or a shortcut on the desktop that points to an executable, the "Security Warning" pops up and asks me "Are you really sure you want to open that? Stuff from the Internet is dangerous!" I don't usually mind this warning and don't want to disable it globally, but now I'm getting it for any executable on the desktop, even ones that I didn't download from the Web and don't have the Mark of the Web alternate data stream. (That is, streams -d * shouldn't and doesn't help.) This started fairly recently, but I can't really point to anything I did that triggered it. It only occurs in one user account on the machine; the other account doesn't have this problem. Running System Restore didn't help. How can I fix the problem and make the pop-up warning appear only when it's supposed to?

• Tool needed for remote software deployment to Windows PC's over internet

  - by user56527

  Hi Can anyone recommend a commercial software package that enables automated rollouts of a bespoke software package across the internet? We are looking at approximately 1000 remote PC's that our organisation owns, geographically scattered and with varying bandwidths available from a central site. The PC's are not manned, they are used as server machines. The tool needs to have some scripting facilities too. The tool needs to be able to push software to the remote site in an automated way. We also need it to be able to reboot the remote machine too. Any ideas anyone? thanks.

• Howto print from dumb terminals with local print server and remote hosted RDP

  - by Matt

  We have essentially a remote office with about 5 dumb terminals. The terminals are connecting to our office directly over a wireless link. What I want to do is connect all their printers onto a print server. But since the remote office is not actually allowed to see our LAN (since they are actually another company) we don't want a full on open VPN tunnel set up. Naturally the RDP traffic passes through a firewall. Is there an easy way to set up the RDP server so that it can see a print server on a remote LAN?

• Notepad Automatically Launches Upon Boot Up of my Windows 7 64-Bit Desktop PC

  - by Simon

  Around 12 months ago, When my Windows 7 PC boots up, Notepad started to appear automatically on the desktop (as a duplicate ie one on top of the other), both displaying the same writing inside, and the name of the Notepad was: desktop-Notepad. [.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21787 I cant remember the exact details as its been so long now but a friend told me, this was due to a "hidden attribute" belonging to notepad becoming "unhidden"and therefore showing itself on the desktop at startup. He showed me a series of steps to either hide the attribute again or to delete it ( telling me that upon restart of my computer it would be recreated/regenerated.) I did indeed follow his guidance however after trying to hide it or delete it (it was never recreated after restart which supposedly it should have done) One notepad still is autolaunched with the text as shown above everytime I startup my PC. As I found this forum I thought I might try again for a solution to prevent notepad from launching. Thankyou

• Windows 7 Computer Maintenance - Restore removed Desktop Shortcuts

  - by HaydnWVN

  I'm aware about the inbuilt nightmate 'tool' of Microsofts which is making every network administrators job a nightmare (if left turned on). In short it'll happily delete every desktop shortcut to a network resource. We have it disabled by default. My question is related to recovering these shortcuts, Windows doesn't seem to dump them into the Recycle Bin and although you can 'restore previous versions' of the Desktop folder, you are unable to do it with the user logged in... Rather a problem if you only have the 1 user account. We have a user who (although the 'Computer Maintenance' tool is turned off) had it come up in 'Action Centre' and chose to run it. I've been unable to reproduce it, but the tool has certainly run (and removed 24 shortcuts from her desktop) although it is still saying 'Windows is not checking your system for maintenance problems'. ?! Very fustrating! Any ideas if these shortcuts are backed up/moved elsewhere so i can easily find and restore them?

• Remote Yum mirror

  - by specto

  I have a bunch of remote computers that must be updated to the most recent packages for RedHat 4 and RedHat 5. I am using mrepo to mirror the RHN packages, however the remote computers do not have an internet connection. Because of this I have to update the mirror server that is part of the remote computers with a dvd. This is to cut down shipping costs to just a dvd. I am attempting to script this so I can fit all of the new packages on a CD or a DVD. I send updates about once or twice a month depending on package requirements. So my question is, is their a good method to do this so that the only things transferred are the new packages? I wish I could just use rsync. Thanks.

• What's wrong with my custom .desktop xsession?

  - by Noam Gagliardi

  I want to create a custom Xmonad session that loads an .xsession script in my home folder. This is the original file I copied. This one works: [Desktop Entry] Encoding=UTF-8 Name=XMonad Comment=Lightweight tiling window manager Exec=xmonad Icon=xmonad.png Type=XSession This is my modified file, xmonad-custom.desktop. When I logout, then login choosing this "xmonad-custom", the screen just flashes and sends me back to the ubuntu login screen (as if it briefly logs in and out of the session): [Desktop Entry] Encoding=UTF-8 Name=XMonad Custom Comment=Lightweight tiling window manager Exec=/home/{username}/.xsession Icon=xmonad.png Type=XSession X-Ubuntu-Gettext-Domain=gdm I also tried without the last line. This is my ~/.xsession file, in case there's an error with this script: #!/bin/env bash xrdb -merge .Xresources trayer --edge top --align right --SetDockType true --SetPartialStrut \ true --expand true --width 15 --height 12 --transparent true --tint 0x000000 & dropbox start & exec xmonad

• What is the best software for desktop recording?

  - by Ivo Flipse

  I know this question is partially a stub from: http://superuser.com/questions/201/free-desktop-recording-screencasting-on-windows However I would have to use this at work, so it doesn't have to be free, just work very well. Lended from the free post: I would expect such an application to have these features: choose the whole desktop, a region, a window to record zoom in an area, and camera move save the recorded movie to a compressed format have basic editing tools have the mouse highlighting feature highlight window/field on the screen, any trick will do display pressed keys/key combinations (like iphone does) So the question is: Which desktop recording/screencasting software would you recommend?

• Laptop connected to external monitor results in desktop overflow

  - by Andrew Fox

  I have a laptop (MSi FX600) connected to an external monitor (Toshiba 19AV500U) with the screen resolution set to the monitors recommended setting of 1440x900. The problem is the desktop is overflowing the display, meaning all edges of the desktop are cut off, so I cannot see the close, minimize buttons on the top and I only see half of the taskbar at the bottom. I have tried many different resolutions but none of them solve the problem. I have had this same problem when connecting to other external monitors in the past, but not all of them, it seems to be fairly random. I have tried to find a way to manually adjust the resolution but I cannot see a way to do this in my settings. All windows updates are up to date, I am connecting through an HDMI cable and I have it set to display only on the external monitor and not extended desktop.

• IIS web service responds on server, not from remote client

  - by Aharon Manne

  I have installed a web service on a server running IIS (v6, as far as I can tell). There is another service installed, which responds as expected. My service responds correctly when a browser is pointed to localhost, but there is no response when a remote client tries to query the service. Fiddler on the remote client simply reports a timeout. Wireshark on the remote client shows no response at all from the server, no NACK, nothing. Wireshark on the server detects no query at the relevant port (the service is installed on port 8080). There are no relevant entries in the event viewer. Obviously there is some issue of permissions or authentication. I have tried to compare my service to the service that works, but I have not been able to locate relevant parameters. Any help would be greatly appreciated.

• PHP Mail Relay via Remote smtp Server

  - by Toqeer

  We have a php application running on Linux which sends emails to there users. Currently its setup like php.ini is configured to send via local sendmail server but we have separate mail server for our organization for this domain. I want to send the php application emails via that remote smtp server so these emails can have the correct SPF records and sign via DKIM. But I could not see such option in php.ini to specify the remote host address to forward emails to that, its for windows only. I saw some post which suggest phpMailer but I could not find how to configure that so all our php application could send via our remote SMTP.

• Remote Access Without Explicit Permission: Convenience or Liability?

  - by routeNpingme

  For outsourced professional IT remote support, one habit most new technicians get into is the "instead of getting the user to start up remote support each time, I'll go ahead and install LogMeIn / GoToMyPC / Remote Desktop / whatever so that if they call again, I can just jump on and help them". This of course opens up a potential liability because a client PC on a network that we don't own is being accessed without a user explicitly providing permission by clicking a "Yes, allow technician to control my PC" option. I realize the rules totally change when you're an IT admin over a network that you "own", but this is outsourced IT support. Just curious what others' policies are. Is this an acceptable practice for convenience and I'm turning into one of those "security is more important than anything" people, or is this really a liability?

• rsync remote to local automatic backup

  - by Mark Molina

  Because all my work is stored on a remote server I would like to auto backup my server monthly and weekly. My server is running Centos 5.5 and while searching the web I'm found a tool named rsync. I got my first update manually by using this command in terminal: sudo rsync -chavzP --stats USERNAME@IPADDRES: PATH_TO_BACKUP LOCAL_PATH_TO_BACKUP I then prompt my password for that user and bob's my uncle. This backups the necessary files from my remote server to my local device but does somebody know how I can automate this? Like automatic running this script every sunday? EDIT I forgot to mention that I let direct admin backup the files I need and then copy those files from the remote server to a local server.

• scp to remote servers stalls, unable to isolate cause

  - by Rolf

  When I copy a large file (100+mb) to a remote server using scp it slows down from 2.7 mb/s to 100 kb/s and downward and then stalls. The problem is that I can't seem to isolate the problem. I've tried 2 different remote servers, using 2 local machines (1 osx, 1 windows/cygwin), using 2 different networks/isps and 2 different scp clients. All combinations give the problem except when I copy between the two remote servers (scp). Using wireshark I could not detect any traffic volume that would congest the network (although about 7 packets/sec with NBNS requests from the osx machine). What in the world could be going on? Given the combinations I've used there doesn't seem to be any overlap in the thing that could be causing the trouble.

• Unable to connect to remote MS SQL Server 2008 Express SP3 instance by name

  - by Max

  I am trying to connect to a remote MS SQL Server 2008 SP3 x86 Instance using it's name. At the first glance all seems to work well (e.g. it is possible to connect to the server locally and succesfully telnet it's port remotely), but there is a thing I can't understand... This line should connect us to the default instance of remote SQL Server: osql -S ServerIP -d MyDatabase /U sa -P MyPassword and it does the trick, however the next one: osql -S ServerIP\MyInstance -d MyDatabase /U sa -P MyPassword ends up with the following error: [SQL Native Client]SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. [SQL Native Client]Login timeout expired [SQL Native Client]An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. The only instance running on the server is MyInstance, which is (I guess) the default one. Could you please put some time in explaining the issue.

• Key modifiers affect remote VNC sessions in OS X

  - by Michael

  I have two concurrent users of my MacBook: one local (with local peripherals) and one remote (connecting via VNC to a user kept logged in with fast user switching). As described here http://macosx.com/forums/howto-faqs/52547-howto-simultaneous-user-environments-via-vnc.html That's working fine, except that when I hit modifier keys (e.g. shift, option, ...), I also affect the remote user. For example, if I hold down shift, the remote user's key strokes are capitalised, and if I hold down option, they get strange glyphs instead of the normal letters. Does anyone have any idea what could be causing this, or how to fix it?

• Nagios remote monitoring: NRPE Vs. SSH

  - by sam

  We use Nagios to monitor quite a few (~130) servers. We monitor CPU, Disk, RAM and a few other things on each server. I've always used SSH to run the remote commands, purely because it requires little to no additional config on the remote server, just install nagios-plugins, create the nagios user and add the SSH key, all of which I've automated into a shell script. I've never actually considered the performance implications of using SSH over NRPE. I'm not too bothered about the load hit on the Nagios server (It's probably over-speced for what it does, it's never been over 10% CPU), but we run each remote check every 30 seconds and each server has 5 different checks performed. I assume SSH requires more resources for each check but is there a huge difference? (I.E. enough of a difference to warrant the switch to NRPE). If it's any help, we monitor a mix of physical servers (Normally with 8, 12 or 16 physical cores) and Amazon EC2 medium/large instances.

• Files and folders disappeared from my desktop

  - by Rob

  Suddenly all files, folders and icons that were on my desktop have disappeared. tried making "show hidden files", no luck. tried using recovery software, but it did not find any of this files, so I assume they were not deletes. c:/Users/<myname>/Desktop does look empty from the Explorer, as well as from cmd. installed MalwareBytes, it did find and remove some malware, but it didn't seem to help. used RogueKiller and it did find some suspicious registry called "HideDesktopIcons". ¤¤¤ Registry Entries : 4 ¤¤¤ [HJ DESK] HKCU\[...]\ClassicStartMenu : {59031A47-3F72-44A7-89C5-5595FE6B30EE} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\NewStartPanel : {59031A47-3F72-44A7-89C5-5595FE6B30EE} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\ClassicStartMenu : {20D04FE0-3AEA-1069-A2D8-08002B30309D} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\NewStartPanel : {20D04FE0-3AEA-1069-A2D8-08002B30309D} (1) -> REPLACED (0) I deleted this registry, rebooted, it only unhid My Computer and User icons, but my desktop stuff is still missing — any ideas what should I do next?

I'm at my wits end, any help would be greatly appreciated.

• Redirect audio from laptop to desktop over LAN

  - by Ram Rachum

  I want to be able to play a song on my laptop and have it sound through my desktop's (infinitely better) speakers. If you're familiar with Input Director: I want something that is to audio what Input Director is to mouse/keyboard. I want something that automatically redirects all audio from the laptop to the desktop in real time, and I want that solution to require, like Input Director, minimum maintenance. Beyond the initial setup, I don't want to have to babysit the program that does this. I want something that launches automatically with Windows and just works, and also allows me to cancel it whenever I want. And also doesn't go crazy when the laptop is turned on in a different network where the desktop computer isn't available. Any suggestions for such a program? (I use Windows XP on both computers.)

• use correct-resolution background desktop image

  - by Rob Bos

  I have a desktop background image (a picture) in a half-dozen different resolutions, that I'd like to deploy to a disparate collection of computers with different monitors and video cards and whatnot. Laptops, netbooks, desktops, widescreen, and even a couple of "tall" screens. I have images to cover most of the cases. I would like Windows 7 to correctly pick the correct desktop background image via group policy. Now, the logon screen is already done. The OEMBackground method is rather clever, and lets you copy files of different resolutions to the machine, and the logon app will calculate the aspect ratio of the monitor and match it to a file as closely as possible. Is there any way to have that functionality on the desktop background as well?

• software to view logs on remote server

  - by Tarun

  I have configured syslog server on my linux machine like this Linux Machine (syslog client) -- Linux Machine (syslog server) I have configured it and its working properly. Now, the problem is I want to look at the logs located on remote server in a particular directory for example /var/log/host-ip/httpd.log. One way is that I use ssh for that and then see those logs using commands like tail etc. So is there any Browser based graphical utility which I can use on my machine in which I just give the remote folder location, ip-address etc. and the software shows me the logs present on that remote server. Thanks.
