Rad Inks Secure FTP Client - Change notes
The current version of the Rad SFTP software is 2.02. This document is for historical purposes only.
- Speed Increase.
- It was noted that the applet was not running as fast as it
could. We identified the bottleneck to be the way in which the progress
bar was being updated. Version 1.60 includes a completely different
progress bar and as a result the speed of upload and download have seen
a big improvement. It should also be added that SFTP file transfers are always
slower in comparision to HTTP or FTP file transfers regardless of the client being used.
- All new progress bar
mentioned the progress bar of the FTP applet was changed to increase
the speed of the data transfer but we didn't stop there. The applet now
indicates the time elapsed, time remaining as well as the upload speed.
- Toolbar background color
- In previous version when you used the bgcolor
parameter to change the color of the applet, the color change would be
restricted to the main body, the toolbar did not change its color. This
behavior has been changed and from 1.60 onwards the toolbar will take
on the color that is specified with the bgcolor parameter.
Changes in Version 1.50
- Public Key Authentication
- The previous versions of the applet only supported keyboard interactive authentication. The user
was expected to type in a username and password. The new version of the client will attempt to login using the public key authentication based on the keys stored in your id_dsa file.
- Resume Interrupted Uploads and Downloads
This is perhaps the most requested feature since we released our SFTP client more than an year ago. When attempting to carry out an upload or download and a file by the same name exists on the destination folder you now have three choices. You can either over write the existing file, append to the file or simply ignore the file.
The second option; append allows you to resume an interrupted file transfer. If the sizes of the destination and source files are equal, the destination will be unchanged.
- Chmod dialog changed
In previous versions of the applet and the desktop client the chmod dialog box did does display the permissions that have already been assigned to a file, the user had to bring up the properties dialog to
determine the existing permissions.
The new version displays the current permission with in the chmod dialog box if a single file is selected making the client easier to use
- File Transfer Speed Improvement
The speed of both file uploads and downloads have been improved. The change is most noticeable over high speed connections.
- Better Connection Reuse
Rad SFTP is a multithreaded client and allows you to carry out several uploads and downloads simultaneously. This results in more than one secure connection being established with the server at any given time.
In all previous versions of the applet a connection pool was maintained and whenever possible an existing
idle connection was used instead of opening up new connections. This mechanism has been improved in the new version leading to greater efficiency.
- Knows Hosts
- From version 1.50 onwards the applet will open your known_hosts files (if one exists) and validate the host key presented by the server against the keys in your file. In previous versions the useruser was always prompted even if the key was present in the known_hosts file.
