UC-7112-LX Plus Software User’s Manual Managing Communications

4-2

Telnet / FTP

In addition to supporting Telnet client/server and FTP client/server, the UC-7112-LX Plus also

supports SSH and sftp client/server. To enable or disable the Telnet/ftp server, you first need to

edit the file

/etc/inetd.conf

Enabling the Telnet/ftp server

The following example shows the default content of the file /etc/inetd.conf. The default is to

enable the Telnet/ftp server:

discard dgram udp wait root /bin/discard

discard stream tcp nowait root /bin/discard

telnet stream tcp nowait root /bin/telnetd

ftp stream tcp nowait root /bin/ftpd -l

Disabling the Telnet/ftp server

Disable the daemon by typing ‘#’ in front of the first character of the row to comment out the line.

DNS

The UC-7112-LX Plus 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 you use #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 if the DNS server’s IP address is 168.95.1.1:

nameserver 168.95.1.1

10.120.53.100 – PuTTY

root@Moxa:/etc# cat 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

root@Moxa:/etc#

/etc/nsswitch.conf

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