Secure Shell Access (SSH) and available commands explained.
OSWave offers you access to the Linux system shell using ssh (Secure Shell Access) client.
Most of the Linux distributions have built in ssh clients which you can run by just typing ssh at the command prompt, for Windows there is a free client software called PuTTY which you can download here.
Basic information on what can be achieved using Linux shell is available on the linuxcommand.org site.
To access OSWave from Linux running system please type:
[root@linux]# ssh -l admin 192.168.1.251
And you will be provided OSWave command prompt:

Most of the regular Linux shell commands are available:
oswave>ls /bin

In this example br0 is a bridge interface, eth0 is physical ethernet interface (it is added to the br0 bridge), eth1 is a virtual radio interface (it is added to the br0 bridge too), lo is a loopback interface and wifi0 is a physical radio interface.
- iwconfig is part of the wireless tools for Linux package and is used to show and configure wireless interface settings.

- Wireless Driver used in OSWave is based on MadWiFI project and you may find these docs:
useful to find what and how can be configured.
Following commands are used to manipulate the wireless interface:

- eeprom command provides information about RF module built into the device running information. Sample output of eeprom command is available here. What is important is that using eeprom command you can read real tx power information stored in RF module EEPROM and therefore know what transmit power is available at what frequency.
- tc command is used to manipulate Quality Of Service (QOS) settings.

Writing own startup scripts in OSWave
The /mnt system partition is provided for the user to store files there. Content of the /mnt partition is preserver during reboots and power cycles which means that once you put any file there you still will have access to it after device reboot or power off / power on.
There are two files on the /mnt partition that require extra attention.
The first file is named modules:
oswave>ls -l /mnt -rw-rw-rw- 1 root root 442 modules oswave>
It is there from the first boot and you shall not delete it. It contains list of kernel modules that are loaded during the device startup:
oswave>cat /mnt/modules # /mnt/modules: kernel modules to load at boot time. # # This file should contain the names of kernel modules that are # to be loaded at boot time, one per line. Comments begin with # a `#', and everything on the line after them are ignored. #ebtables #ebt_802_3 #ebtable_filter #ebt_ip #ip_tables #ip_conntrack #ip_conntrack_ftp #ip_conntrack_irc #iptable_nat #ip_nat_ftp #ip_nat_irc #ipt_conntrack #iptable_filter #ipt_mac #ipt_MASQUERADE #ipt_multiport oswave>
If you are writing your own startup scripts and use iptables and/or ebtables then you need to uncomment required module names here in order for your scripts to work.
The second important file is named init.sh and is a user startup script that is executed during device boot time.
oswave>ls -l /mnt -rw-rw-rw- 1 root root 442 modules -rw-r--r-- 1 admin admin 108 init.sh oswave>cat /mnt/init.sh #!/bin/sh echo "Hello World" echo "This is my startup script that will run each time the device boots up" oswave>
Using built in text editor (pico, nano or vi) you can modify the init.sh script:
oswave>pico /mnt/init.sh
GNU nano 2.0.2 File: /mnt/init.sh Modified #!/bin/sh echo "Hello World" echo "This is my startup script that will run each time the device boots up" ^G Get Help ^O WriteOut ^R Read File ^Y Prev Page ^K Cut Text ^C Cur Pos ^X Exit ^J Justify ^W Where Is ^V Next Page ^U UnCut Text^T To Spell
Reseting OSWave to default settings.
Should you happen to write a startup script that crashes your OSWave system at startup it is possible to restore your device to factory default settings and prevent running that script at the startup. In order to do so you need to press and keep the built in reset button at the device startup for 20 seconds. OSWave will revert to factory default settings and reboot itself.
Sample startup scripts and command examples.
