comment Find a particular nesting of directory names, e.g. …/project/dir1/dir2
This seems to work. I tried it earlier and it didn't work but I'm away from my Ubuntu install and was trying to prototype this on an OS X machine. Works on my *nix machine. I should have expected that the BSD find wouldn't work the same.

comment X11 forwarding an OpenGL application from a machine running an NVIDIA card to a machine with an AMD card
I was unable to get gazebo to work, but I'm marking this as the accepted answer because your suggestions were technically correct. I am able to tunnel glxdemo using all of the suggestions you made (ssh and xserver/xclient over the network) but Gazebo itself just seems to not build branching code paths and it assumes that it own't be run in this weird configuration. Thanks!.

comment X11 forwarding an OpenGL application from a machine running an NVIDIA card to a machine with an AMD card
The computers are already on the same network, but we'd like to move all of our gazebo machines in to a server closet at some point but still have the software's visuals available to us which is why I'm looking in to SSH tunneling. Unless you're saying that having them on the same network allows for a different configuration that makes SSH not necessary (I'm guessing setting up some crazy xhost/client setup, I don't know much about X11).

comment I want to expose “easy” URL's for machines on a home network. Is custom DNS/BIND the answer?
DHCP is provided by the router, a Cisco Linksys E4200v1; not sure how customizable it is, but I don't want to go down the Tomato route because the 5GHz builds aren't stable and I love my 5GHz. In regards to the web interfaces, I am not using any HTTP servers; the HTTP handling is baked in to the individual daemons. That said, I could probably set up a really simple nginx layer in front that does exactly what you're suggesting. Thanks for the tips, I think that knowing whether or not BIND could resolve to specific ports is a good place for me to start.

@MichaelKjörling I know, but when most people talk to me about .local it usually turns out that they're talking about it as it works on OS X or other systems set up for mDNS since that's where it's typically used. I still should have thought of it though. Thanks for the clarification.

@MichaelKjörling my only reservation in using mDNS is that not everything supports it. I could configure Avahi on the *nix boxes, and most of us use OS X, but as near as I can remember (it's been a while) Windows doesn't do Zeroconf/mDNS unless you install a bunch of Bonjour stuff. Unless you were just suggesting that I do regular DNS but use that as my TLD, in which case that's a pretty good idea I suppose, haha.

@Caleb ba-dum-psh. It's actually Robonaut 2.

@Caleb it looks like it's okay for me to say it now; it's because the machine will eventually belong to NASA but I work from my own personal laptop. @simplicityFirst I wanted to background Eclipse, not the ssh connection.

comment Pass the background flag (&) through expect and ssh
Neat approach, I may end up using both; only because after I launch Eclipse and do some work, I tend to close it but remain connected to the box. The headless box is actually a robot brain that we develop directly on instead of cross compiling so it's a pony that does far too many tricks for a narrow scope solution; that's why I tried to make such a generic script. But it's a good solution for long periods of time in the dev phase. Also, thanks for adding the expect tag.

gotcha. I understand what you're saying now.

Didn't notice you were escaping the space as well. While I don't think this would make the command not work, it's not necessary. Reflected this in a reply to your comment below too.
