Telnet (Java)
A Java-based Telnet client is delivered through the remote user's Web browser. The remote
user can specify the IP address of any accessible Telnet server and the SRA appliance will
make a connection to the server. Communication between the user over SSL and the server
is proxied using native Telnet. The Telnet applet supports MS JVM (Microsoft Java Virtual
Machine) in Internet Explorer, and requires Sun Java Runtime Environment (JRE) 1.1 or
higher for other browsers.
SSHv1 and SSHv2 (Java)
Java-based SSH clients delivered through the remote user's Web browser. The remote user
can specify the IP address of any accessible SSH server and the SRA appliance will make
a connection to the server. Communication between the user over SSL and the server is
proxied using natively encrypted SSH. The SSHv1 applet supports MS JVM in Internet
Explorer, and requires SUN JRE 1.1 for other browsers. SSHv2 provides stronger
encryption and has other advanced features, and can only connect to a server that supports
SSHv2. SSHv2 support sets the terminal type to VT100. SSHv2 requires JRE 1.6.0_10 or
higher, available from http://java.sun.com.
FTP (Web)
Proxy access to an FTP server on the internal network, the Internet, or any other network
segment that can be reached by the SRA appliance. The remote user communicates with
the SRA appliance by HTTPS and requests a URL that is retrieved over HTTP by the SRA
appliance, transformed as needed, and returned encrypted to the remote user. FTP supports
25 character sets, including four Japanese sets, two Chinese sets, and two Korean sets. The
client browser and operating system must support the desired character set, and language
packs may be required.
File Shares (CIFS)
File Shares provide remote users with a secure Web interface to Microsoft File Shares using
the CIFS (Common Internet File System) or the older SMB (Server Message Block)
protocols. Using a Web interface similar in style to Microsoft's familiar Network
Neighborhood or My Network Places, File Shares allow users with appropriate permissions
to browse network shares, rename, delete, retrieve, and upload files, and to create
bookmarks for later recall. File shares can be configured to allow restricted server path
access.
Remote Desktop Protocols and Virtual Network Computing
RDP Java and VNC are supported on Windows, Linux, and Mac operating systems, while
RDP ActiveX is supported only on Windows. Most Microsoft workstations and servers have
RDP server capabilities that can be enabled for remote access, and there are a number of
freely available VNC servers that can be downloaded and installed on most operating
systems. The RDP and VNC clients are automatically delivered to authorized remote users
through their Web browser in the following formats:
