Chapter 9 Accessing and Monitoring PIX Firewall

Using Telnet for Remote System Management

The recurring keyword indicates that summer time should start and end on the days specified by the

values that follow this keyword. If no values are specified, the summer time rules default to United States

rules. The week option is the week of the month (1 to 5 or last). The weekday option is the day of the

week (Sunday, Monday,…). The month parameter is the full name of the month (January, February,…).

The hh:mm parameter is the time (24-hour military format) in hours and minutes. The offset option is

the number of minutes to add during summer time (default is 60).

Use either of the following commands when the recurring keyword cannot be used:

clock summer-time zone date date month year hh:mm date month year hh:mm [offset]

clock summer-time zone date month date year hh:mm month date year hh:mm [offset]

The date keyword causes summer time to start on the first date listed in the command and to end on the

second specific date in the command. Two forms of the command are included to enter dates either in

the form month date (for example, January 31) or date month (for example, 31 January).

In both forms of the command, the first part of the command specifies when summer time begins, and

the second part specifies when it ends. All times are relative to the local time zone.

If the starting month is after the ending month, the Southern Hemisphere is assumed.

The zone parameter is the name of the time zone (for example, PDT) to be displayed when summer time

is in effect. The week option is the week of the month (1 to 5 or last). The weekday option is the day of

the week (Sunday, Monday,…). The date parameter is the date of the month (1 to 31). The month

parameter is the full name of the month (January, February,…). The year parameter is the four-digit year

(1993 to 2035). The hh:mm parameter is the time (24-hour military format) in hours and minutes. The

offset option is the number of minutes to add during summer time (default is 60).

To set the time zone for display purposes only, enter the following command:

clock timezone zone hours [minutes]

The clock timezone command sets the time zone for display purposes (internally, the time is kept in

UTC). The no form of the command is used to set the time zone to Coordinated Universal Time (UTC).

The zone parameter is the name of the time zone to be displayed when standard time is in effect. The

hours parameter is the hours offset from UTC. The minutes option is the minutes offset from UTC.

The clear clock command will remove the summer time setting and set the time zone to UTC.

Using Telnet for Remote System Management

Note SSH provides another option for remote management of the PIX Firewall when using a less secure

interface. For further information, refer to “Using SSH for Remote System Management.”

The serial console lets a single user configure the PIX Firewall, but often this is not convenient for a site

with more than one administrator. PIX

Firewall lets you access the console via Telnet from hosts on any

internal interface. With IPSec configured, you can use Telnet to remotely administer the console of a

PIX

Firewall from lower security interfaces.

This section includes the following topics:

• Configuring Telnet Console Access to the Inside Interface, page 9-17

• Allowing a Telnet Connection to the Outside Interface, page 9-18

• Using Telnet, page 9-20

• Trace Channel Feature, page 9-21
