How to Modify the /etc/remote File

You may need to perform this procedure to access the system console via a tip connection from a Sun server running an older version of the Solaris OS software.

You may also need to perform this procedure if the /etc/remote file on the Sun server has been altered and no longer contains an appropriate hardwire entry.

Before You Begin

This procedure assumes you are connecting via tip line from serial port B (ttyb) of a Sun server to the serial port (ttya) of the Sun Fire V490 machine.

What to Do

1.Determine the release level of system software installed on the Sun server. To do this, type:

#uname -r

The system responds with a release number.

2.Do one of the following, depending on the number displayed.

■If the number displayed by the uname -rcommand is 5.0 or higher:

The server software shipped with an appropriate entry for hardwire in the /etc/remote file. If you have reason to suspect this file was altered and the hardwire entry modified or deleted, check the entry against the example given in CODE EXAMPLE 7-1, and edit it as needed.

hardwire:\ :dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:

CODE EXAMPLE 7-1Entry for hardwire in /etc/remote (Recent System Software)

Note – If you intend to use the Sun server’s serial port A rather than serial port B, edit this entry by replacing /dev/term/b with /dev/term/a.
