Using ctelnet in Sun Cluster software with secure shell

Wednesday, 8 September 2004, 11:33 AM EST

You can use the ctelnet application in Sun Cluster software to connect to systems by means of the ssh command instead of telnet. The ctelnet tool is part of the Sun Cluster Console (SUNWccon) package in Sun HPC ClusterTools software.

The ctelnet application is a GUI used to run interactive commands simultaneously on systems with identical software configurations. By default ctelnet uses telnet for communication. In some environments this is a disadvantage because:

* All systems must run a telnet server; in hardened configurations this would not be desirable.
* Communication between ctelnet and the systems is not encrypted; sensitive information such as passwords is sent in clear text.

Note: It is not necessary to have a cluster configured in order to make use of this Tech Tip. ctelnet is usually used to connect to identically configured systems in a cluster, but this is not a requirement here. You can connect to any group of systems.
