DNS

The UC-8410A-LX supports DNS client (but not DNS server). To set up DNS client, you need to edit three

configuration files:

/etc/hosts, /etc/resolv.conf, and /etc/nsswitch.conf.

/etc/hosts

This is the first file that the Linux system reads to resolve the host name and IP address.

/etc/resolv.conf

This is the most important file that you need to edit when using DNS for the other programs. For example,

before using

#ntpdate time.nist.goc to update the system time, you will need to add the DNS server

address to the file. Ask your network administrator which DNS server address you should use. The DNS server’s

IP address is specified with the

nameserver command. For example, add the following line to /etc/resolv.conf

file if the DNS server’s IP address is 168.95.1.1:

nameserver 168.95.1.1

10.120.53.100 – PuTTY

moxa@Moxa:~$ sudo cat /etc/resolv.conf

# resolv.conf This file is the resolver configuration file

# See resolver(5).

#nameserver 192.168.1.16

nameserver 168.95.1.1

nameserver 140.115.1.31

nameserver 140.115.236.10

/etc/nsswitch.conf

This file defines the sequence to resolve the IP address by using /etc/hosts file or /etc/resolv.conf.

IPTABLES

IPTABLES is an administrative tool for setting up, maintaining, and inspecting the Linux kernel’s IP packet filter

rule tables. Several different tables are defined, with each table containing built-in chains and user-defined

chains.
