commit 56456f2f515340359c823c51aa8c0a118cf060bf
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:12:03 2013 -0800
Updated class models, URLs and views to support SSH.
Tons of new methods, URLs, and such -- mostly cut and pasted from VNC.
commit 4d1d0c2a4fc3ca42d743f75fc9cd71a6069c948d
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:11:04 2013 -0800
Add separate tab for SSH and transform jsterm.html to use jsTerm!
The separate tab is temporary for testing purposes.
commit 32c8094ce6e0908ba4efc2b7283deb9ddf9635f6
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:10:15 2013 -0800
Protective int casts!
They may not be requird, but they're in the other routine so I put them in this one.
commit 9b2b6c38632f19905100860ffaf20dcad36b41a7
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:09:53 2013 -0800
Added support for reaching new static jsTerm files.
The static files are now reachable via 'jsterm'.
commit 4ba42de164769fa58a6ef6ccc10e003360b1e3a8
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:09:00 2013 -0800
Added ssh_popout.html.
This is required for feature compatibility.
commit bc15477e4726cfd715894b2aa596f0784f2af5ce
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:08:32 2013 -0800
Added jsTerm.js
The analogue to noVNC.js, where the magic should begin happening!
commit 6b454d2aa7881ae5f3c40bf1602199e1dbf2be97
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:08:03 2013 -0800
Added jsTerm.
The entire jsTerm package is in the top level of the project.

commit 56456f2f515340359c823c51aa8c0a118cf060bf
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:12:03 2013 -0800
Updated class models, URLs and views to support SSH.
Tons of new methods, URLs, and such -- mostly cut and pasted from VNC.
commit 4d1d0c2a4fc3ca42d743f75fc9cd71a6069c948d
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:11:04 2013 -0800
Add separate tab for SSH and transform jsterm.html to use jsTerm!
The separate tab is temporary for testing purposes.
commit 32c8094ce6e0908ba4efc2b7283deb9ddf9635f6
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:10:15 2013 -0800
Protective int casts!
They may not be requird, but they're in the other routine so I put them in this one.
commit 9b2b6c38632f19905100860ffaf20dcad36b41a7
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:09:53 2013 -0800
Added support for reaching new static jsTerm files.
The static files are now reachable via 'jsterm'.
commit 4ba42de164769fa58a6ef6ccc10e003360b1e3a8
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:09:00 2013 -0800
Added ssh_popout.html.
This is required for feature compatibility.
commit bc15477e4726cfd715894b2aa596f0784f2af5ce
Author: Jack Twilley <j...@osuosl.org>
Date: Fri Dec 27 17:08:32 2013 -0800
Added jsTerm.js
The analogue to noVNC.js, where the magic should begin happening!
commit 6b454d2aa7881ae5f3c40bf1602199e1dbf2be97
Author: Jack Twilley <j...@osuosl.org>
