--- at our institution, we have four Windows 7 spectrometer workstations. I had the computers registered in the university intranet with IPs not accessible from outside and use RealVNC for remote access. The university provides VPN access which can be used in case one has to access the spectrometer from outside the intranet. I'm very satisfied with this solution and thus haven't considered using other protocols such as SSH so far. --- I am not sure what you have in mind but I installed teamviewer (https://www.teamviewer.com/en/) on all the computers driving the spectrometers and use it to run experiments remotely whenever necessary. --- I use TeamViewer. It's fantastic --- I've been using TeamViewer without issue, but unfotunately they seem to be buckling down on what they term as commercial use (academic institutions are apparently considered commercial in their book!). The costs are ongoing and quite high, but the facility is very useful so I'm probably going to purchase a licence shortly. --- Since Windows to Windows connection is trivial i.e. Remote Desktop, I am suspecting that you are looking at more like a -nix to Windows platform connection. I haven't had to deal with this per se since all my NMR hosts run on Linux platforms but I would way, you can use an implementation of 'wine' on Linux/Unix side and try a Remote desktop connection to the Windows node that controls the spectrometer. --- I think cygwin is the best because of its completeness. But, I guess a VirtualMachine would work as well. --- We have used "Tightvnc" but I guess I'm wondering on how you intend to use it. We have only on Windows spectrometer host, and we have setup the VNC server such that only staff know the VNC password. That way if a user reports a problem we can login remotely to troubleshoot. Do you want to allow users to have remote access? Why not use Windows Remote Desktop? Alternatively, TopSpin has a remote capability. Through the software, you can drive TopSpin, but you do not have access to other application on the workstation itself. On our linux hosts, it is possible to connect using VNC. The user has to login to their own account on the workstation using SSH, and then initiate the VNC service. Then you can open a VNC client window and drive the spectrometer remotely. When you sever the connection, the VNC service terminates. I know people have used TeamViewer, and many people are quite fond of it. It does work pretty well, but our Computer Support team have pointed to some known security issues with Teamviewer. As we have confidential client data on our workstations, the CS team have advised us to stay away from Teamviewer on any system with client data. --- we use teamviewer around these parts. It can connect w/o hassle across a variety of different OS combinations (win-RHEL, Win-Mac, etc.) and is super hassle-free. The realtime response is reasonable as well. ---- Chrome Remote Desktop works fine. --- it may be not the answer to your question, but we successfully used the programm Teamviewer for accessing our Win7 based Topspin acquisition computers. http://www.teamviewer.com/en/ By installing a process running a permanent server on that specific machine, a permanent connection is established to a relay server at this company, tunneling the strictest firewalls (Skype principle). By authentication at this relay server you can access your computer either using a client program or even by a web interface in your favorite browser... --- I have been using the Bitvise software (server and client) for years for the remote access a PC not connected to the NMR spectrometer, but I do not think this would make a difference: https://www.bitvise.com/ We have Linux boxes on our spectrometers and I also use their client installed on Windows PC to create an SSH tunnel to Linux and run VNC server there. --- I have run the Cygwin ssh server on a Windows computer, not sure whether it was Windows 7. I did not use it in conjunction with a VNC server, but that should be possible, I think Cygwin comes with a vnc server, but I am not sure. Cygwin also comes with a bash shell. Did you try to use the Remote Desktop feature in Windows ? That is the way I usually remotely connect to Windows computers, and Remote desktop clients are available for Linux and Mac computers as well (if you want to connect from non Windows clients). Our spectrometers are all Linux, and I am running x11vnc on all of them for remote control of acquisition. A useful tool in that conjunction is the Tightvnv Java VNC viewer that supports ssh: http://www.tightvnc.com/ssh-java-vnc-viewer.php That way users don't need to install VNC software on their clients, but just access the java through a link on our website (which in turn is only accessible to users) -- Sameer Al-Abdul-Wahid, Ph.D. Manager, Nuclear Magnetic Resonance Centre University of Guelph 50 Stone Road East, Guelph, ON N1G 2W1 Tel: 519-824-4120 x58914 Web: http://nmr.uoguelph.ca/Received on Wed Jun 15 2016 - 03:10:02 MST
