SRX650 Services Gateway Secure CLI Access Overview

Telnet allows you to connect to the SRX650 Services Gateway and access the CLI to execute commands from a remote system. Telnet connections are not encrypted and therefore can be intercepted.

Note: Telnet access to the root account is prohibited. You must use more secure methods, such as SSH, to log in as root.

SSH provides the following features:

The SSH client software must be installed on the machine where the client application runs. If the SSH private key is encrypted (for greater security), the SSH client must be able to access the passphrase used to decrypt the key.

For information about obtaining SSH software, see and

If you are using a Junos XML protocol server to configure and monitor devices, you can activate cleartext access on the services gateway to allow unencrypted text to be sent directly over a TCP connection without using any additional protocol (such as SSH, SSL, or Telnet). For more information about the Junos XML management protocol, see the Junos XML Management Protocol Guide.

Note: Information sent in cleartext is not encrypted and therefore can be intercepted.

If the services gateway is operating in a Common Criteria environment, see the Secure Configuration Guide for Common Criteria and Junos-FIPS.
