So for todays challenge I'm trying to come up with a solution to view my MacLab computers as a set of thumbnails for ease of monitoring and troubleshooting. Macs make remote viewing pretty straightforward and easy on a 1:1 level, simply enable Screen Sharing or Remote Management in the sharing tab of the preferences and then navigate to the machine in the network directory, click the Share Screen button, enter credentials and you're there. This is great for troubleshooting individual machines however I'm interestyed in finding a solution which allows me to monitor a series of machines at the same time without having to establish 25 seperate connections.
While there are many paid options (Apple offers one that is supposedly stellar . . . for $300+) I'm gonna do my Lassalian best to find a free OpenSource option. To that end I am playing with a Java application called VncThumbnailViewer which seems to do the trick without a bunch of bells and whistles. First thing to do is to activate the VNC server on the remote computer . . . in OSX 10.6 the control is located within the sharing tab of the preferences. Check & highlight the "Remote Management" box and then click on the "Computer Settings" button on the right. In the resulting dialog box check the "VNC viewers may control screen with password:" box and enter a password.
Now back on the viewing computer open up the VncThumbnailViewer, go to File>Add New host and enter the appropriate information and you should see your computer screen pop up in the window. So far the only problem I am encountering is that my computer names and their host names aren;t jiving up together, for some reason the machines have retained the hostname of a machine which previously populated the IP address (I'm in a static IP environment for this project) so now I will look into that.
And that was simple enough . . . gotta love Sudo . . . in order to change the hostname just go into a teminal and run
sudo hostname new_hostname
replacing new_hostname with your new hostname.
