User Level

Syntax

set port-buffering [duplicate-nfs-to-syslog onoff]

 

[keys-stroke-buffering onoff] [mode offlocalremoteboth]

 

[nfs-directory <text>] [nfs-encryption onoff]

 

[nfs-host <config_host>] [time-stamp onoff]

 

[view-port-buffer-string <text>]

Options

duplicate-nfs-to-syslog

 

When enabled, buffered data is sent to the syslog host to be viewed on the host’s

 

monitor. The default is off.

 

key-stroke-buffering

 

When enabled, key strokes that are sent from the network host to the serial device on

 

the IOLAN’s serial port are buffered. The default is off.

 

mode

 

Specifies where the port buffer log is kept, either Off, Local, Remote, or Both. If

 

Remote or Both is selected, you must specify an NFS server location for the port buffer

 

log.

 

nfs-directory

 

The directory and/or subdirectories where the Remote Port Buffering files will be

 

created. This field is used when Port Buffering Mode is set to Remote or Both. For

 

multiple IOLANs using the same NFS host, it is recommended that each IOLAN have

 

its own unique directory to house the remote port log files. The default is

 

/device_server/portlogs.

 

nfs-encryption

 

Determines if the data sent to the NFS host is sent encrypted or in the clear across the

 

LAN. The default is set of Off.

 

NOTE: When NFS encryption is enabled, the Decoder utility software is required to be

 

installed on the NFS host for decrypting the data to a readable format. The Decoder

 

utility software can be found on the installation CD-ROM and on the www.perle.com

 

website.

 

nfs-host

 

The NFS host that the IOLAN will use for its Remote Port Buffering feature. The

 

IOLAN will open a file on the NFS host for each reverse SSH or reverse Telnet line,

 

and send any port data to be written to those files. The default is None. This field is

 

required when Mode is set to Remote or Both.

 

time-stamp

 

Enable/disable time stamping of the port buffer data.

 

view-port-buffer-string

 

The string (up to 8 characters) used by a a session connected to a serial port to display

 

the port buffer for that particular serial port. You can specify control (unprintable) codes

 

by putting the decimal value in angle brackets < > (for example, Escape b is <027>b).

 

The default is ~view.
