Two executable files, tcps2-release and tcps2-debug, are created.
tcps2-release—an ARM platform execution file (created specifically to run on the IA3341)
tcps2-debug—an ARM platform GDB debug server execution file (see Chapter 5 for details about
the GDB debug tool).
NOTE If you get an error message at this point, it could be because you neglected to put tcps2.c and
tcpsp.c in the same directory. The example Makefile we provide is set up to compile both tcps2
and tcpsp into the same project Makefile. Alternatively, you could modify the Makefile to suit
your particular requirements.
Uploading and Running the “tcps2-release” Program
Use the following commands to use FTP to upload tcps2-release to the IA3341.
1. From the PC, type:
#ftp 192.168.3.127
2. Next, use the bin command to set the transfer mode to Binary, and the put command to
initiate the file transfer:
ftp> bin
ftp> cd home
ftp> put tcps2-release

- The following instructions give the steps required to save the firmware file to the ia3341 s ram disk and how to upgrade the firmware 23
- Type the following commands to enable the ram disk 23
- Type the following commands to use the ia3341 s built in ftp client to transfer the firmware file ia3341 x x frm from the pc to the ia3341 23
- Loading factory defaults 24
- Backing up the user directory 25
- Create a backup file first type the following command to enable the ram disk upramdisk next use the file system backup utility provided by moxa backupuf mnt ramdisk usrfs backup 25
- Deploying the user directory to additional ia3341 units 25
- For some applications you may need to ghost one ia3341 user file system to other ia3341 units back up the user file system to a pc refer to the previous subsection backing up the user file system for instructions and then type the following commands to copy the backup to additional ia3341 units 25
- Ia3341 linux user s manual managing embedded linux 25
- Once the file system is backed up use ftp to transfer the file usrfs backup to your pc 25
- Upramdisk cd mnt ramdisk upfirm usrfs backup 25

- Enabling and disabling daemons 26
- Ia3341 linux user s manual managing embedded linux 26

- Next use vi to open your application program we use the example program tcps2 release and set it to run in the background 26
- Starting a program automatically at run level 26
- The following daemons are enabled when the ia3341 boots up for the first time 26
- To set a private daemon to run at run level you can edit the file rc local as follows 26
- Type the command ps ef to list all processes currently running 26
- Cd etc rc d init d 27
- Cd etc rc d rc3 d ln s etc rc d init d tcps2 s60tcps2 27
- Edit a shell script to execute root tcps2 release and save to tcps2 as an example 27
- Ia3341 linux user s manual managing embedded linux 27
- In this section we outline the steps you should take to set the linux run level and execute requests use the following command to enable or disable settings 27
- Setting the run level 27
- Sxxrunfile stands for s start the run file while linux boots up xx a number between 00 99 the smaller number has a higher priority runfile the file name 27
- You will find that the following daemons are enabled after you reboot the system 27
- Adjusting the system time 28
- Ntp client 28
- Setting the time manually 28
- Cron daemon to execute scheduled commands 29
- Updating the time automatically 29

- Web service apache 32
- Ia3341 linux user s manual managing communications 34
- Install php for apache web server 34
- Note the cgi function is enabled by default if you want to disable the function modify the file etc apache conf httpd conf when you develop your own cgi application make sure your cgi file is executable 34
- Step 1 check that you have enough free space the following figure illustrates how to check that the dev mtdblock3 has more than 3 mb of free space 34
- Step 2 type upramdisk to get the free space ram disk to save the package 34
- This embedded computer supports the php option however since the php file is 3 mb it is not installed by default to install it yourself first make sure there is enough free space at least 3 mb on your embedded flash rom 34
- Ia3341 linux user s manual managing communications 35
- Step 3 download the php package from the cd rom you can find the package in cd rom target php php tgz 35
- Step 4 untar the package to do this type the command tar xvzf php tgz 35
- Iptables 36
- Define policy for chain rules 39
- Observe and erase chain rules 39
- Append or delete rules 40
- Nat area private ip 41
- Nat example 41
- 12 4 12 42
- Dial up service ppp 42
- Enabling nat at bootup 42
- Ia3341 linux user s manual managing communications 42
- In most real world situations you will want to use a simple shell script to enable nat when the ia3341 boots up the following script is an example 42
- Modem ppp access is almost identical to connecting directly to a network through the ia3341 s ethernet port since ppp is a peer to peer system the ia3341 can also use ppp to link two networks or a local network to the internet to create a wide area network wan 42
- Note click on the following links for more information about ppp http tldp org howto ppp howto index html http axion physics ubc ca ppp linux html 42
- Ppp point to point protocol is used to run ip internet protocol and other network protocols over a serial link ppp can be used for direct serial connections using a null modem cable over a telnet link and links established using a modem over a telephone line 42
- The pppd daemon is used to connect to a ppp server from a linux system for detailed information about pppd see the man page 42
- Example 1 connecting to a ppp server over a simple dial up connection 43
- Example 2 connecting to a ppp server over a hard wired link 44
- How to check the connection 44
- Setting up a machine for incoming ppp connections 45

- Step 4 type command tar xvzf net snmp tgz to untar the package 50
- Step 5 run install sh and select to install the snmp daemon 50

- Ia3341 linux user s manual managing communications 51
- Step 6 run the command snmpd c etc snmpd snmpd conf to wake up snmp daemon 51
- Step 7 use snmp client to query from target for testing 51
- The following simple example allows you to use an snmpwalk program on the host site to query the ia3341 which is the snmp agent the ia3341 will respond 51
- Uage like snmpwalk v 1 c public target ip 51
