ECE Guacamole




Guacamole -- Screen Size Problem

There is a problem when reconnecting to existing sesions where the screen size becomes very small. I know about this problem and I'm working on fixing it. But until I figure it out, this is a work-around.

If your screen is not the proper size:

This will need to be done everytime you reconnect. I know its a pain, I'm working on it...


Guacamole -- Login Problem

If you are having trouble login into the Guacamole page, it is possible that your password has expired. Passwords are set to expire once a year. The guacamole login does not tell you that your password has expired, it just does not allow you to login!

To fix this, go here and login with your VT PID/password. Then Edit your account to change your password. There is an oddity with the "Edit" account where you must select your (one and only) account from the drop down list.

Please let me know if something is not working: john.ghra (at) vt.edu.


Guacamole -- A Web Browser Interface to the ECE Linux Machines

Guacamole provides a way of using the Linux machines without having to install any software, you just use your web browser.

Problems and Bugs:

If you find something not working, please let me know: john.ghra (at) vt.edu. If you don't let me know of problems, I can't fix them!

Known problems and work arounds:

Connection fails with strange messages.
This seems to happen when several people try to connect at the same time. For now, just try to reconnect, it almost always works the second (or third) time.

Text is a little fuzzy / blurry to read.
Click the <CTRL><SHIFT><ALT> key combination. Scroll all the way to the bottom. Uncheck Automatically fit to browser window.

The initial connection to a machine takes a while.
Just be patient. When you reconnect to a machine, its pretty quick.

There is a copy&paste clipboard between your computer and the remote computer. This does not work for all combinations of (local computer, browser, remote computer).
I will try to post updates about this.

This type of connection is slow and laggy.
Yes. There is probably nothing I can do about that. If you want a more responsive interface, you will probably need to do a native X windows connection.
