• Navigating nested RDP sessions

  - by U62

  Often at work I have to RDP into one server in order to get to another. And no, there's no chance of the network getting sorted out such that I can connect to all machines directly :) I'm wondering if anyone has any good tips/tricks for working in this scenario. I tend to open RDP sessions full screen, so the way to get back to my desktop is to click the minimize or restore buttons on the toolbar the drops down from the top of the screen when you are using a full-screen RDP session. The problem is that when you log into A and then from there log into B, A's toolbar covers B's, so there's no easy way to get back to the desktop of A without logging out of B. At least as far as I can see. Maybe there's a keyboard shortcut that can pop you out of the innermost session? At the moment, I try to not use full screen mode on the nested session, but apart from having to remember to set that before I connect, it reduces the workspace and is something I'd like to avoid.

• Problem opening files with Gvim and NERDTree on Windows 7

  - by Oscar Duignan

  Just installed gvim on windows 7 for the first time, and I'm having a problem opening some files. When I open files (I'm doing this through NERDTree,) vim seems to flash up a cmd window for a few second before closing it (too quickly to make out the contents,) and I end up with a C:/Program folder, and a /Files/vim/vimfiles/doc/ in the directory of the file I just opened. I can see it's trying to access C:/Program Files/vim/vimfiles/doc, which is where vim is installed, however it's choking on the space, and I'm not familiar enough with gvim to work out why. Any and all ideas are greatly appreciated.

• HTTP Requests Fails for WordPress sites after upgrading from PHP 5.2 to PHP 5.3

  - by anjanesh

  I've upgraded from Ubuntu 9.10 to 10.04 beta 1 and PHP got upgraded from 5.2 to 5.3 Now all my WordPress & Magento sites arent working. I tried retrieving the URL headers from the command line, but HTTP request fails. Utilizing get_headers in a small script, PHP Warning: get_headers(http://local.vhosts1.com): failed to open stream: HTTP request failed! in get_headers.php on line 12 But HTTP request fails only for WordPress and Magento based sites - not custom written ones. Does this probably have to do with some htaccess directive ?

• How can I deskew and crop PDFs made from scanned pages *automatically*? [closed]

  - by Pietro M.

  I have several PDFs made up of book pages' scans. The scans are made from two pages at a time and some of these scans are skewed, making text appear slightly tilted. I'm looking for a tool that could allow me to do an automatic optimization by deskewing the scans without losing readability. I've found the GPL software briss to crop the scans in order to have a 1:1 page ratio instead of 2:1, but I don't have any tool to deskew the pages. I stumbled upon unpaper, another open source tool that seems perfect for what I want to do, but that tool is Linux only and it doesn't work on PDF files directly. Any hint is appreciated.

• Ubuntu to Ubuntu VNC over SSH tunnel

  - by rxt

  I have a Linux Ubuntu desktop at home, ssh enabled, vnc server installed, router rule configured. It all works, and at home I can connect via the local network from my Mac. From the outside I can login via ssh. I've configured putty as follows: session: host name and port number connection ssh tunnel: forwarded ports: L5900|192.168.0.23 the local address is: 192.168.1.45 When I make the connection I can login to the remote machine. Then I open Remote Desktop Viewer. I click connect protocol: vnc host: ? use host as ssh tunnel: ? I don't know what to use for the last two options. Which ip-addresses should I use?

• OpenVPN bandwith restrictrictions and cpu power needed

  - by user197664

  In Open VPN is there a way to set a maximum limit of data and speed per user? Say user "reptar' is abusing the VPN and I wanted to limit his/her speeds and/or data how would one go about doing this? Would I need to know the IP address of the abuser? Also, I have seen articles around the internet about turing a Rasberry PI in to a VPN server. If I did such a thing how many users would this device be able to handle at a given time? I believe it runs at 512 gb and clocks at around 700 mhz.

• Enable hardware virtualization in BIOS?

  - by rhon

  I am running a FOXCONN AM2+ M61PMV with an AMD Athlon II X2 240 Windows 7 ultimate 64 bit. From startup I have hit the del key and the options for enabling the hardware virtualization are not there. I have checked the Microsoft tool that says I can run virtual and i have checked SecurAble, that says yes. But I have an open case w/microsoft (they've been trying for a week [7 tech support people later]) and they're saying that I need to ensure that the hardware is enabled. Where do I go to see? Is there another way besides from the startup?

• Automator apps with different icons that persist upon saving

  - by ashcatch

  Automator allows to save a workflow as an application bundle. It uses an Automator specific icon for doing this. I want to change this icon (using different icons for different workflows). I can do this by going into the application bundle and change the icon with Icon Composer. The disadvantage of this solution is that if I open the application bundle in Automator and save it, it uses the default icon again. Is there a way to change the icon for good?

• Outlook 2010 corrupts all Office attachments on a Server 2008R2 Remote Desktop Server

  - by Zhadu

  I have a rather annoying problem with a clients new Remote Desktop server. The problem is that any and all Office attachments (tested with Word and Excel documents) sent to the users via email cannot be opened due to the file seemingly being corrupted/damaged. I have determined that it is a local problem on the server, as the attachments work fine on my own pc. Also I believe the problem is isolated to Outlook, as the users can open already stored Office files without any issues. What are your thoughts on this? Extra information: The server is running Microsoft Server 2008 R2. The Office is a version 2010. It is handeling the roles of AD and RDS - The client only has one server, hence the breach of best practise. There is currently no AV software on the server. I have tried running a repair as well as a reinstalling of Office, with the error still there.

• Is it possible to run two separate instances (copies, versions) of Audacity?

  - by cipricus

  What I want is two separate instances of Audacity running in parallel as to separate programs with different settings. I want one to use WASAPI as audio host and speakers as input device (the 2.0.5 portable has the WASAPI option), and the other to use the MME as audio host, and microphone as input device. When opening a new (second) window of the same installation/copy of Audacity, by executing twice the .exe file, it is the same as giving the command 'new' under 'File', what happens is not a second instance, but just a separate project/file and window. When settings are changed in one, they change exactly in the other. When trying to start a second copy of Audacity, or even a second different version, when one is already running, it will also open just a second project/file of the application that is already running, as before.

• forwarding port 3306 on macosx in order to connect to a remote mysql db

  - by Jonathan Mayhak

  I'm on macosx 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

• Can i safely block all ports on my sever

  - by Saif Bechan

  I have a web server running pleks and get attacked a lot every day. I configured a firewall, and there are some predefined services such as www, and ftp, etc. I am planning to block all the ports except for the www port and the PLESK port. When I need ftp or ssh access for example i will open the ports in PLESK and then start to work. Is this a good thing to do or are there some downsides on doing this. There are some ports I am not sure of, such as SMTP,POP3,IMAP, DNS. Can i close these ports or is there no need to do so.

• Vista: "connect to a network" does not load (can't set up VPN)

  - by Arkaaito

  I'm trying to connect to my office VPN from home. One small problem: my home desktop uses Vista (64-bit, Ultimate edition). On Vista, you're supposed to set up a VPN like so: Open the control panel Click on Network Click on "Connect to a Network" Configure a new connection of type "Office" The problem is, when I click on the link for "Connect to a Network", nothing happens. Can anyone suggest how I should go about troubleshooting this? (Or am I better off just upgrading to Windows 7?)

• mime-attachment incompatibility on forwarded messages from android to an iphone

  - by Peter Carrero

  A couple of guys got the evo android in the office. I got an iphone. When I receive a forwarded email from one of those phones, the forwarded piece comes as a mime-attachment that the iphone cannot open. I also tried this with a motorola droid and got the same result. I am not sure if the issue is the android sending the message on the wrong format or the iphone not being able to understand a mime type that it should... Has anyone experienced this, and, most importantly, found a fix/workaround? Thanks.

• Could not retrieve backup settings for primary ID in Log shipping

  - by user1723139

  I am doing log shipping between two Amazon EC2 instances running Windows Server 2008 R2 with SQL Server 2008 R2 standard edition. Both the instances are in the same domain and I can access the shared folders between the instances. The SQL server service account, agent service account are all running under a domain account. When I activate log shipping (with stand by mode restore in secondary server), the initial backup gets restored on the secondary. After that the backup operation is getting failed and i get the following error message: *** Error: Could not retrieve backup settings for primary ID 'xxxxxx-xxxx-xxxx-xxxx-4d772cd7337e'.(Microsoft.SqlServer.Management.LogShipping) *** *** Error: Failed to connect to server IP-0A7653F2.(Microsoft.SqlServer.ConnectionInfo) *** ****** Error: A network-related or instance-specific error occurred while establishing a connection to SQL Server.******** **The server was not found or was not accessible.

• Use a webpage as a screen saver

  - by Stephen

  We have a number of retail stores that sell laptops. There are a number of display models on show in each retail store. At the moment screen savers are used to promote different offers and these screen savers are out of date. What I would like to do is open up a browser on these machines and just use a webpage. This way I can control exactly what is displayed and keep it up to date with our latest offers. Is it possible to have the webpage in full screen mode, with no address bar or tabs visible. As far as I'm aware these are Windows machines, probably running Windows Vista or Windows 7. Any help appreciated.

• Running scheduled web scripts in a Windows Server environment

  - by Dan Murfitt

  I'm trying to get a scheduled web script running on a Windows Server and so far the only way I've managed to automate this process is by using the Task Scheduler to open Internet Explorer with the web address as a parameter. I then need to create a separate task to run just after this task to close Internet Explorer (otherwise the task doesn't complete). Is there a better way of doing this? I've also managed to run the script by calling the web address through a Telnet connection to the web server (GET /web/address/here) but I haven't found a way of automating this process on a scheduled basis. Any ideas appreciated

• How compatible are VMWare and VirtualBox?

  - by MikeKusold

  At my workplace, everyone uses VMware Player (and some people have licenses for Workstation). We frequently share VMs to save time on development setup. However, I would really like to take advantage of the Snapshot feature in VirtualBox since I am unable to acquire a license for Workstation. I have read that VirtualBox has no issues reading VMWare VMs (including VMs with snapshots). However, I'm worried about how compatible things are the other way. In VirtualBox, I open up a VM created in VMware and create multiple snapshots. Can the resulting files be opened in VMware?

• Not able to connect to perforce server outside of localhost

  - by bobber205

  My setup is a Qwest PK5000 router with a Linksys router running Tomato. I have DMZ pointed towards my router. (The server is on the tomato router). I tried my applications that open up sockets and Utorrent (port 6883) and I ended having to do advanced port forwarding and forward specific ports in addition to having DMZ on my router. The problem is that I cannot connect to perforce when on another machine on the LAN or off. Any ideas? :) Thanks!

• On a Mac, how are connections (possibly by spyware) made to outside internet addresses during initia

  - by TT

  I am trying to secure a Mac after discovering that network links are being established to some unwanted internet sites. Using 'lsof -i' (list open 'files', internet) I have seen that launchd, ntpd, firefox, dropbox and other processes are either 'LISTENING' or have 'ESTABLISHED' links to a site or sites which I suspect have to do with spyware. I have been trying to find startup files and preference lists that initiate thise links but can't find them. I could easily reinstall the OS and restore data from a backup but I'd prefer to know how to fix this as I have six Macs to look after. Thanks...

• Linux Disk Setup for VMs

  - by zjherner

  Been trying to find the ideal way to setup disks/partitions for Linux guests on ESXi. Seems as though Linux is falling behind when it comes easily adding disk space. The end goal is to be able to add disk space to a Linux server without rebooting the server or taking the server offline. Ideally, I would expect adding disk to a Linux machine should be as easy as adding disk space to a Windows machine. I expand the vmdk file from vSphere Open disk mangler find the disk and extend volume. Would have to use command line tools in linux which is no big deal, but I haven't been able to find a solid way to exand filesystems on the fly. What is everyone else using for disk setups on their linux guests? Has anyone been able to acheive adding storage space to linux without downtime? Can it be done without using lvm?
