• Your configuration files or shell scripts can use “exit” or a command line consisting of a single “!”
to have the ZyWALL exit sub command mode.
• Include
write
commands in your scripts. Otherwise the changes will be lost when the ZyWALL
restarts. You could use multiple
write
commands in a long script.
Note: “exit” or “!'” must follow sub commands if it is to make the ZyWALL exit sub
command mode.
See Chapter 39 on page 499 for more on configuration files and shell scripts.
I cannot get the firmware uploaded using the commands.
The Web Configurator is the recommended method for uploading firmware. You only need to use
the command line interface if you need to recover the firmware. See the CLI Reference Guide for
how to determine if you need to recover the firmware and how to recover it.
My packet capture captured less than I wanted or failed.
The packet capture screen’s File Size sets a maximum size limit for the total combined size of all
the capture files on the ZyWALL, including any existing capture files and any new capture files you
generate. If you have existing capture files you may need to set this size larger or delete existing
capture files.
The ZyWALL stops the capture and generates the capture file when either the capture files reach
the File Size or the time period specified in the Duration field expires.
My earlier packet capture files are missing.
New capture files overwrite existing files of the same name. Change the File Suffix field’s setting
to avoid this.
44.1 Resetting the ZyWALL
If you cannot access the ZyWALL by any method, try restarting it by turning the power off and then
on again. If you still cannot access the ZyWALL by any method or you forget the administrator
password(s), you can reset the ZyWALL to its factory-default settings. Any configuration files or
shell scripts that you saved on the ZyWALL should still be available afterwards.
Use the following procedure to reset the ZyWALL to its factory-default settings. This overwrites the
settings in the startup-config.conf file with the settings in the system-default.conf file.
Note: This procedure removes the current configuration.
