ECE Guacamole

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, to here 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.

Problems and Bugs:

If you find something not working, please let me know: john.ghra (at) 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.
