Management Access for the SRX550 High Memory Services Gateway
Telnet allows you to connect to the SRX550 High Memory Services Gateway and access
the CLI to execute commands from a remote system. Telnet connections are not
encrypted and therefore can be intercepted.
NOTE: You cannot use Telnet to access the root account. You must use more
secure methods, such as SSH, to log in as root.
SSH provides the following features:
•
Allows you to connect to the services gateway and to access the CLI to execute
commands from a remote system
•
Unlike Telnet, encrypts traffic so that it cannot be intercepted
•
Can be configured so that connections are authenticated by a digital certificate
•
Uses public–private key technology for both connection and authentication
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 http://www.ssh.com and
http://www.openssh.com.
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
Configuration Guides for Junos OS Public Sector Certifications.
