WML Sumo Thin Client User Guide
Administrator and Power User Tools
The Sumo bundles a few programs which system administrators and power users will find useful.
These are available from the command line, which can be accessed by checking the “allow user to
open a terminal” checkbox on the “System” tab of the Setup Manager. A “Terminal” button will
appear in the Connection Manager.
Using the terminal, telnet and ssh connections may be made with the full range of options available.
Power users may also wish to make rdesktop RDP connections or vncviewer connections using the
command line, but note that these connections will not be managed, and can't be switched between
using the Ctrl-Alt-Down key combination.
The Sumo comes with a very simple vi editor, and the more useful GNU Nano text editor. Nano can
be launched using either the “nano” command, or its alias “edit”.
Files can be transferred using scp (secure copy – part of the openssh toolkit) or sftp. Files may be
downloaded using wget, or the lightweight Dillo web browser.
Startup script
The Sumo may be controlled using an optional startup script. This script is executed after all kernel
modules have been installed, and after the network has been configured. It can be used to configure
a wireless network card or set up NFS network mounts or indeed, anything that may be necessary to
prepare the Sumo to work on your network, or support your embedded Mono/.NET applications.
To add a script, edit a file called /etc/persistent/startup.sh and make it executable:
edit /etc/persistent/startup.sh
Add lines; the script is a busybox shell script:
#!/bin/sh
# Comments start with a # character
/bin/echo “test file” > /etc/persistent/output.txt
Now make it executable:
chmod a+x /etc/persistent/startup.sh
The script will now be executed every time the Sumo boots.
