Appendix B
Using Out-of-Band Access to Transfer Files
This appendix describes how to use the
xmodem
command to perform
out-of-band file transfers. The
xmodem
command enables you to transfer files
between remote workstations and Bay Networks routers when all IP routing paths
between them are down. You cannot use the
xmodem
command to transfer files
between Bay Networks routers.
Overview
Both UNIX and 386/486 DOS remote workstations allow you to log in to the
Technician Interface port of a router and enter
xmodem
commands. However,
each type of workstation uses a different utility program for opening and closing
out-of-band (dial) connections between workstation and router.
With a Sun workstation, you initially establish a connection by configuring and
running the Terminal Interface Program (TIP). The program has two associated
files, /etc/phones and /etc/remote, in which you can enter setup information such
as the telephone number of a remote router (/etc/phones) and modem interface
settings (/etc/remote). You run the program by entering a
tip
command with
appropriate syntax at the UNIX command line prompt.
With a 386/486 DOS workstation, you initially establish a connection by
configuring and running the Bay Networks Terminal Program (file name wfterm).
To run the program, click on the Wfterm icon in the display of your Site Manager
workstation.
