8. Set up DNS

If you are using DNS servers supplied by your ISP, edit the file

/etc/resolv.conf by adding the following lines of code:

nameserver ip_addr_of_first_dns_server

nameserver ip_addr_of_second_dns_server

For example:

nameserver 168.95.1.1

nameserver 139.175.10.20

9. Use the following command to create a pppoe connection:

pppd ixp0

The ixp0 is what is connected to the ADSL modem LAN port. The example above uses LAN1.

To use LAN2, type:

pppd ixp1

10. 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.

11. If you want to disconnect it, use the kill command to kill the pppd process.

NFS (Network File System)

The Network File System (NFS) is used to mount a disk partition on a remote machine, as if it

were on a local hard drive, allowing fast, seamless sharing of files across a network. NFS allows

users to develop applications for UC-7402, without worrying about the amount of disk space that

will be available. UC-7402 supports NFS protocol for both client and server.

Setting up UC-7402 as an NFS Server

By default, UC-7402 enables the service /etc/init.d/nfs-user-server. The service link file

S25nfs-user-server is located in the directory /rc.d/rc2.d-rc5.d.

Edit the NFS server configuration file /etc/exports to set up the remote host (NTF client) list and

access rights for a specific directory. The file formats are shown below:

#vi /etc/exports

File Format:

directory machine1(option11,option12) machine2(option21,option22)
