UC-8410/8416/8418/8430 Managing Communication The UC-8410/8416/8418/8430/8430 supports the following sub-modules. Be sure to use the module that matches your application.
UC-8410/8416/8418/8430 Managing Communication # iptables [-t tables] [-FXZ] -F: Flush the selected chain (all the chains in the table if none is listed). -X: Delete the specified user-defined chain. -Z: Set the packet and byte counters in all chains to zero. Examples: # iptables -L -n In this example, since we do not use the -t parameter, the system uses the default ‘filter’ table. Three chains are included: INPUT, OUTPUT, and FORWARD.
UC-8410/8416/8418/8430 Managing Communication --dport: Destination port number. -j: Jump target. Specifies the target of the rules; i.e., how to handle matched packets. For example, ACCEPT the packet, DROP the packet, or LOG the packet. Examples: Example 1: Accept all packets from lo interface. # iptables –A INPUT –i lo –j ACCEPT Example 2: Accept TCP packets from 192.168.0.1. # iptables –A INPUT –i eth0 –p tcp –s 192.168.0.1 –j ACCEPT Example 3: Accept TCP packets from Class C network 192.168.1.
UC-8410/8416/8418/8430 Managing Communication NAT Example The IP address of LAN1 is changed to 192.168.3.127 (you will need to load the module ipt_MASQUERADE): 1. #echo 1 > /proc/sys/net/ipv4/ip_forward 2. #modprobe ip_tables 3. #modprobe iptable_filter 4. #modprobe ip_conntrack 5. #modprobe iptable_nat 6. #modprobe ipt_MASQUERADE 7. #iptables -t nat –A POSTROUTING –o eth0 –j SNAT --to-source 192.168.3.

UC-8410/8416/8418/8430 Managing Communication How to check the connection Once you’ve set up a PPP connection, there are some steps you can take to test the connection. First, type: /sbin/ifconfig (The folder ifconfig may be located elsewhere, depending on your distribution.) You should be able to see all of the network interfaces that are UP.
UC-8410/8416/8418/8430 Managing Communication Setting up a Machine for Incoming PPP Connections This first example applies to using a modem, and requires authorization with a username and password. pppd/dev/ttyM0 115200 crtscts modem 192.168.16.1:192.168.16.2 login auth You should also add the following line to the file /etc/ppp/pap-secrets: * * ““ * The first star (*) lets everyone login. The second star (*) lets every host connect.
UC-8410/8416/8418/8430 # other accounts that should guest hostname “*” master hostname “*” root hostname “*” support hostname “*” stats hostname “*” Managing Communication not be able to use pppd! - “username@hinet.net” is the username obtained from the ISP to log in to the ISP account. “password” is the corresponding password for the account. 5. Edit the file /etc/ppp/options and add the following line: plugin pppoe 192.168.3.
UC-8410/8416/8418/8430 Managing Communication 8. Use the following command to create a pppoe connection: pppd eth0 The eth0 is what is connected to the ADSL modem LAN port. The example above uses LAN1. To use LAN2, type: pppd eth1 9. Type ifconfig ppp0 to check if the connection is OK or has failed. If the connection is OK, you will see information about the ppp0 setting for the IP address. Use ping to test the IP. 10. If you want to disconnect it, use the kill command to kill the pppd process.
UC-8410/8416/8418/8430 Managing Communication Example: smtpclient –s test –f < mail-body-message sender@company.com –S -s: The mail subject. -f: Sender’s mail address -S: SMTP server IP address IP_address receiver@company.com The last mail address receiver@company.com is the receiver’s e-mail address. mail-body-message is the mail content. The last line of the body of the message should contain ONLY the period ‘.’ character. You will need to add your hostname to the file /etc/hosts.
UC-8410/8416/8418/8430 Managing Communication OpenVPN OpenVPN provides two types of tunnels for users to implement VPNS: Routed IP Tunnels and Bridged Ethernet Tunnels. To begin with, check to make sure that the system has a virtual device /dev/net/tun. If not, issue the following command: # mknod /dev/net/tun c 10 200 An Ethernet bridge is used to connect different Ethernet networks together. The Ethernets are bundled into one bigger, “logical” Ethernet.

UC-8410/8416/8418/8430 Programmer's Guide Flash Memory Map Partition sizes are hard coded into the kernel binary. To change partition sizes, you will need to rebuild the kernel. The flash memory map is shown in the following table. Address Size Contents 0x00000000 – 0x0009FFFF 640 KB Boot Loader—Read ONLY 0x000A0000 – 0x0027FFFF 1.875 MB Kernel object code—Read ONLY 0x00280000 – 0x00FDFFFF 13.
UC-8410/8416/8418/8430 Programmer's Guide For toolchain v3.x: #export PATH=“/usr/local/arm-linux-4.4.2/bin:$PATH” #export MANPATH=“/usr/local/arm-linux-4.4.2/man:$MANPATH” Alternatively, you can add the same commands to $HOME/.bash_profile to cause it to take effect for all login sessions initiated by this user. Obtaining help Use the Linux man utility to obtain help on many of the utilities provided by the tool chain.
UC-8410/8416/8418/8430 Programmer's Guide This is where 2000 is the network port number on which the server waits for a connection from the client. This can be any available port number on the target. Following this are the name of the program to be debugged (hello-debug), plus that program’s arguments. Output similar to the following will be sent to the console: Process hello-debug created; pid=38 2.
UC-8410/8416/8418/8430 Programmer's Guide Buzzer The device node is located at /dev/console. The UC-8410/8416/8418/8430/8430 supports Linux standard buzzer control, with the UC-8410/8416/8418/8430’s buzzer running at a fixed frequency of 100 Hz. You must include . 1. Function: KDMKTONE ioctl(fd, KDMKTONE, unsigned int arg); Description: The buzzer’s behavior is determined by the argument arg.
UC-8410/8416/8418/8430 Programmer's Guide unsigned long time - The time you wish to ack sWatchDog periodically. You must ack the sWatchDog before timeout. If you do not ack, the system will reboot automatically. The minimum time is 50 msec, and the maximum time is 60 seconds. The time unit is msec. Output If you receive 0 (zero), it means the function is working. If you receive any other number, then there is something wrong with this function.
UC-8410/8416/8418/8430 Programmer's Guide When you “kill the application with -9” or “kill without option” or “Ctrl+c” the kernel will change to auto ack the sWatchDog. When your application enables the sWatchDog and does not ack, your application may have a logical error, or your application has made a core dump. The kernel will not change to auto ack. This can cause a serious problem, causing your system to reboot again and again. 5. User application example Example 1: #include
