NAME

cconsole , ctelnet, crlogin– multi window, multi machine, remote console, login and telnet commands

SYNOPSIS

$CLUSTER_HOME/bin/cconsole [clustername…| hostname…]
$CLUSTER_HOME/bin/ctelnet [clustername…| hostname…]
$CLUSTER_HOME/bin/crlogin [-l user] [clustername…| hostname…]

DESCRIPTION

These utilities initiate a multiple window connection to a set of specified hosts. There are three variations: one that is specifically intended for remote console access while the others provide remote logins using rlogin(1) or telnet(1).

Each utility starts a host window for each of the specified hosts, as well as a common window. Input directed into the common window is sent to each of these host windows.

This tool is useful for system administration tasks that require similar things to be done on each of several hosts. For tasks that are identical on all hosts, typing in the common window sends the characters to all of the hosts. However, the host windows are normal terminal windows so they can also be used one at a time (by moving the mouse into one of them and typing directly into it) to perform host specific tasks.

The common window also allows the user to select which hosts receive the characters typed in the common window, so only the specified hosts will receive input.

These utilities use entries in two different databases, clusters(4) and serialports(4).

cconsole

Remote console access, using cconsole is provided through telnet(1). All normal telnet escape characters are available to the user. See telnet(1) for a complete listing of telnet(1) escape characters. Because there are a few telnet escapes that are commonly used, they are provided here as well. The escape character is Control-], specified below as ‸].

‸] quit

Quit the session. Analogous to ~. in tip(1) and rlogin(1).

‸] send brk

Send a break signal to the remote system. This is what is needed to halt the Sun CPU. The normal key board sequence is “L1-A.”

crologin

One of the options provided with rlogin(1) is also provided with the crlogin utility:

-l user

Specify a username, user for the remote login. The default is to use the local username. The argument value is remembered so hosts and clusters specified later can use the -l option when making the connection.

ctelnet

The ctelnet utility is similar to cconsole except the connection is directly over the Internet.

ENVIRONMENT VARIABLES

CLUSTER_HOME

Location of Sun Cluster System tools. Defaults to /opt/SUNWcluster.
