Obtaining access to the filer shell

Ways to access the command line

The filer supports a command-line interface. You can access the command line

Sharing a single telnet and console session

The console and telnet share a single session. Everything entered through telnet is echoed at the console; everything entered at the console is echoed to the telnet session

telnet session restriction

Only one telnet session can be open at a time.

Closing a telnet session

To close a telnet session, press Ctrl-] to log out of the filer, then press Ctrl-D to log out of telnet.

telnet and console password requirement

Although telnet and the console share the same shell session, telnet and the console each prompt you for a password. Both the console and telnet connections use the same password.

rsh support

The filer supports rsh with trusted remote hosts--those remote hosts listed in /etc/hosts.equiv on the root volume.

In addition to entering rsh commands manually, you can use a shell script or crontab file to enter some commands.


Note: You can use rsh only to enter filer commands. You cannot use rsh to remotely log in to the filer. To log in to a filer remotely from a host, use telnet.


Commands accepted from rsh

The following table lists the filer commands that you can execute using rsh.
cf halt quota sysconfig
cifs httpstat raid sysstat
date mt rdate timezone
df netstat reboot uptime
disk nfsstat restore version
download options route vif
dump partner snap vol
exportfs qtree snmp ypwhich

Use Ctrl-C to abort the command that is running

Ctrl-C aborts whatever command is being run from the console or a telnet session.

Because the console and telnet share a single session, a command entered at the console or through telnet can be terminated inadvertently from either location.

To ensure that a command is not terminated by Ctrl-C, start the command from a trusted host through rsh.

Changing the system password

A system password is required to establish a console or telnet connection with the filer. The password was specified during setup.

You can change the system password at any time with the passwd command. When you enter the passwd command, the filer prompts you to enter the old password, if any, and then requests the new password twice.

Where to go to learn more about security
