HP-UX Secure Shell Getting Started Guide

ClearAllForwardings

Use this directive to specify that all local, remote, and dynamic port forwardings in the

configuration files or on the command line be cleared. This option can be used to clear port

forwarding set in configuration files. It is automatically set by the scp and sftp commands.

The default is setting no.

For example:

ClearAllForwardings yes

Compression

Use this directive to specify whether to use compression. Setting this directive to YES can improve

speed over slower lines. Compression can also reduce delays because of encryption.

The default setting is no.

For example:

Compression yes

CompressionLevel

Use this directive to specify the compression level to use if compression is enabled. Valid values

are integers between 1 (fast) and 9 (slow, best).

The default setting is 6, which is sufficient for most applications.

For example:

CompressionLevel 9

NOTE: The CompressionLevel directive is available for the SSH-1 protocol only.

ConnectionAttempts

Use this directive to specify the number of times a user can attempt to connect to the server (one

per second) before exiting. Valid values must be integers. Use this directive with scripts in case

the connection fails.

The default value is 1.

For example:

ConnectionAttempts 3

ConnectTimeout

Use this directive to specify the timeout (in seconds) when connecting to the HP-UX Secure Shell

server, instead of using the default system TCP timeout. This value is used only when the target

server is down or unreachable.

The default value is 0.

For example:

ConnectTimeout 0

ControlMaster

Use this directive to enable sharing of multiple sessions over a single network connection.

Following are the valid values for the ControlMaster directive:

YES

HP-UX Secure Shell listens for connections on a control socket specified using the control

path value.

HP-UX Secure Shell connects additional sessions to the socket using the same control path.

These sessions reuse the master instance of a network connection than initiating new ones.
