IOLAN
+
- User and Administration Guide
The request is received by all hosts on the network and is
checked against a file to find a match. This data base file will
normally be
/etc/bootptab
and will be of the following format:
# bootptab description
iolan:ht=ethernet:ha=0080d400024e:\
:hd=/tftp:\
:bf=iolan.DL:\
:ip=192.168.209.8:
Where:
ht
is the type of network
ha
is the Ethernet address on back of IOLAN+
hd
is the home directory for specifying IOLAN+ firmware (optional)
bf
is the name of IOLAN+ firmware (optional)
ip
is the IP address you want to use
Note: This BOOTP implementation is a subset and not a full
implementation of the RFC.
Note: The most common error is bad information in the
/etc/bootptab
file (recheck it). See
Troubleshooting
&
Maintenance
(Appendix B) for more information.

Saving and
Downloading
Configurations
It is possible to save the configuration of your IOLAN+. This
is convenient for loading multiple communications servers
with the same setup. It is also advisable as a backup method.
If the boot file name has the extension “.cfg” (eg
iolan.cfg
), it
will be loaded as a configuration file rather than a boot file.
This allows the administrator to configure one IOLAN+, save
its configuration and automatically configure subsequent
units via bootp.
Should the configuration of your IOLAN+ ever be corrupted
because of user error or damage, it is an advantage to have
the configuration stored somewhere for easy re-installation.
