Appendix A.1.3. Setting up Dynamic IP Address

If it is necessary to setup the dynamic IP address for eH880 unit, input the following command to get

the IP address from DHCP server:

# udhcpc –b –i eth0

Appendix A.2. Setting up Network File System (NFS) Server

Appendix A.2.1 PC Side

The exported directories of NFS server are controlled by "/etc/exports" configuration file. To share

the directory of Linux Server with eH880 unit, you need to edit the file.

Sample contents of "/etc/exports" configuration file:

/share1 192.168.1.0/24(ro)

/share2 192.168.1.100(rw)

For example, directory "/share1" can be shared by all devices with IP address starting with

"192.168.1.xxx". Note that "192.168.1.0" is network address and "24" is the short form of

"255.255.255.0" subnet mask. "ro" is used to share directory for read-only while "rw" is used to

share directory for read/write. Directory "/share2" is only shared to the device that has an IP address

equal to "192.168.1.100" for read/write.

After editing the configuration file, restart NFS server for the changes to take effect. Input the following

command to restart NFS server:

# /etc/rc.d/init.d/nfs restart

Appendix A.2.2 eH880 side

In the eH880 unit, you can input the following command to use remote directory that is shared by NFS

server. Assume that the IP address of Linux server is "192.168.1.10".

# mount –o nolock,rsize=1024,wsize=1024 192.168.1.10:/share1 /mnt/ext1

You can change to directory "/mnt/ext1" by inputing "cd /mnt/ext1" command.

Appendix A.2.3 NFS (Network File System)

After logging in the device (telnet), user can mount a directory structure in his PC Linux to a directory

in the device and then use "cp" command to copy files to another directory in the device. To mount a

directory on the command prompt:

"mount -o nolock,rsize=1024,wsize=1024 xxx.xxx.xxx.xxx:/home/user /mnt/ext1"

"cp /mnt/ext1 /usr/local/rw"
