Netwalker
Netwalker is a mailbox utility that allows a port to be used to collect
network connectivity information. This is designed to be used on Netrom/
Thenet type nodes.
Installation of netwalker is thru Desqview. It will require a minimum of
a 43k window. This will yield approximately 10 nodes. A 75K window will
log 375 nodes and 100k will log 630 nodes which is the maximum. The additional
program space is used for the logging function.
The desqview parameters are the same for netwalker as they are for the mailbox.
(See INSTALL.DOC) There are 2 ways to run NW through DesqView. The simplest
is to use a DOS type window that opens in the directory in which NW and the
log files are to be placed. Starting of the program is via the command line
as in the examples below. The second method is to create a specific NW window
with the command line parameters placed on the parameters line.
The NetWalker command line is as follows:
NW <Port> <Opts> <Timeout>
Port
COM Port number as defined by YTNC or BPQHTNC2.
Opts
I=Collects node identification info
N=Collect no extra data
P=Collect node parameters
U=Collect node version
Timeout
Timeout in seconds before disconnect and connection to next node
in the list.
Example: NW 26 N 30
What this means is 'Node, port 26, collect node parameters with 30 sec timeout.
The screen output will be exactly what you will see in the file. Netwalker
will connect to the local node and query it for its information as per the
options selected. It will then disconnect and reconnect to connect to the
next node in the list. It will then collect its routing information.
This will be repeated for as long as there are nodes to connect to. If a node
that is in the routing list cannot be connected to then the timer will
disconnect the tnc from the local node and go to the next node in the list.
The information collected in the file is information about the node and its
routing table. At the bottom of the file there is a summary of Netwalkers
activity.
To stop Netwalker just enter cntl-f.
When NW is started it creates a file called NWLOG.X where X = the number of
the log file. If an existing log file is present each subsequent log file
with have the next sequential number.
When netwalker is stopped it will write 2 files. The log file that is currently
in use and a restart file called nw.dat. When NW is restarted it will resume
where it left off and create a new log file.
If is is desired to start the run from the orginal starting point in the
network the log files and NW.DAT will have to deleted.
