RuggedCom RS400 manual ROS Secure Shell Server

Administration

Typing a new value after pressing enter always erases the old parameter value. The left and right cursor keys can be used to position the edit point without erasing the old parameter value. The up and down cursor keys can be used to cycle through the next higher and lower values for the parameter.

After the parameter has been edited, press enter again to change other parameters. When all desired parameters have been modified, press <CTRL> A to apply changes. The switch will automatically prompt you to save changes when you leave a menu in which changes have been made.

Some menus will require you to press <CTRL> I to insert a new record of information and <CTRL> L to delete a record.

1.1.4 Updates Occur In Real Time

All configuration and display menus present the values at the current instant, automatically updating if changed from other user interface sessions or SNMP. All statistics menus will display changes to statistics as they occur.

1.1.5 Alarm Indications Are Provided

Alarms are events for which the user is notified through the Diagnostics submenu. All configuration and display menus present an indication of the number of alarms (in the upper right hand corner of the screen) as they occur, automatically updating as alarms are posted and cleared.

1.1.6 The CLI Shell

The user interface provides a shell for operations that are more easily performed at the command line. You may switch back and forth from the menu system and shell by pressing <CTRL> S. For more information on the capabilities of the shell see the approapriate chapter of this guide.

1.2 The ROS™ Secure Shell Server

1.2.1 Using a Secure Shell to Access the User Interface

SSH (Secure Shell) is a network protocol which provides a replacement for insecure remote login and command execution facilities, such as telnet and remote shell. SSH encrypts traffic in both directions, preventing traffic sniffing and password theft.

SSH protocol version 2 is implemented in ROS. The authentication method is keyboard interactive password authentication. User name will not be verified in order to grant access to SSH server. The passwords to be used for login are configured in Password Table and user’s privileges are the same as for user logged in via the console port.

1.2.2 Using a Secure Shell to Transfer Files

ROS implements SFTP protocol over SSH to transfer files in secure manner. The file system is created in one directory only. Also, all the files are created in the system at startup time and can not be deleted, created, renamed. Files can be downloaded (upgraded) and uploaded (to be analyzed outside of the unit).

The implemented commands are: dir – a file directory
