Configuring PPPoE

PPPoE relies on two widely accepted standards: PPP and Ethernet, which permit the use of

PPPoE(Point-to-Point Over Ethernet).

PPPoE is a specification for connecting users on an Ethernet to the Internet through a common

broadband medium, such as a single DSL line, wireless device or cable modem, used by many

ADSL service providers. All users on the Ethernet share a common connection, so the Ethernet

principles that support multiple users on a LAN combine with the PPP principles, which apply to

serial connections.

 Create the Connection:

/>pppd pty “pppoe -I <ETHERNET_INTERFACE> -m 1412” user <USER_NAME> password

<USER_PASSWORD>&

<ETHERNET_INTERFACE>: Ethernet card connected to ADSL modem, for example, eth0

<USER_NAME>: User account, for example, moxa@adsl.net

<USER_PASSWORD>: Password for user account

To check if PPPOE is successfully connected, use the command:

 />ifconfig ppp0

How to Mount a Remote NFS Server

Currently, the UC-7101/7110/7112 only supports NFS (Network File System) clients. Users can

open NFS service on a Linux PC to enable the UC-7101/7110/7112 to push data to it. The

UC-7101/7110/7112 can use NFS to mount a remote disk as a local disk for data or log purposes.

1. First, the NFS server must open an export directory and allow access to the IP address. Edit

the file “/etc/exports” on your Linux PC, and then run the NFS daemon. The following

example gives one possibility (refer to the NFS-HOWTO document at

http://nfs.sourceforge.net/nfs-howto/server.html

/home/usr 192.168.3.1 (rw,no_root_squash,no_all_squash)

2. The UC-7101/7110/7112 must run the “portmap” utility. This program is enabled by default

in the “/etc/rc” file. Use the following command to mount the remote NFS server:

/>mount –t nfs <remote-ip>:<remote-export-directory> <local-directory>

Dynamic Driver Module Load / Unload

In addition to supporting traditional static drivers, the UC-7101/7110/7112 also support the

dynamic driver module load / unload mechanism. It allows user to load a special driver into the

kernel to enable hardware features for specific applications. To load / unload a dynamic driver

module, use the following commands.

Load module:

/>insmod <module-directory>/<module file name>

For example, to load the UART driver, type the following command:

/>insmod /lib/modules/2.6.9-MoXaRt/kernel/drivers/char/mxser.ko

Show module list:

/>lsmod

Unload module:

/>rmmod <module-name listed by lsmod command>
