uusnap Command

Purpose

Displays the status of BNU contacts with remote systems.

Syntax

uusnap

Description

The uusnap command displays a table showing the status of the Basic Networking Utilities (BNU). The table includes the following information for each remote system:

Item	Description
`SystemName`	Specifies the name of the remote system.
`Number` `Cmds`	Specifies the number of command files (C.* files) queued for the remote system.
`Number` `Data`	Specifies the number of data transfers (D.* files) queued for the remote system.
`Number` `Xqts`	Specifies the number of remote command executions (X.* files) queued for the remote system.
`Message`	Specifies the current status message for the site, from the /var/spool/uucp/.Status/SystemName file. The `Message` field may include the time remaining before BNU can retry the remote system, and the count of the number of times (if any) BNU has tried unsuccessfully to reach the system.

Example

To see a snapshot of the status of BNU, enter:

uusnap

The output from this command is similar to the following:

nostromo  4 Cmds  2 Data  2 Xqts  SUCCESSFUL
zeus      2 Cmds  1 Data  2 Xqts  NO DEVICES AVAILABLE

These lines indicate that four command files, two data files, and two execute files are currently queued for system nostromo. The last connection to nostromo was successful. The last attempt to contact system zeus, on the other hand, was not successful because no device was available on the local system.
