Disabling the Telnet/TFTP Server

Disable the daemon by typing “#” in front of the first character of the row to comment out the line. For example,

to disable the TFTP server, use the following commands:

telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd

#tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd

/srv/tftp

After you finish writing or modifying the code, remember to execute “umount /” to change the root directory

back to Read-only mode.

MOXA:~# umount /

DNS Client

The V2616A-LX supports DNS client (but not DNS server). To set up DNS client, you need to edit three

configuration files: /etc/hostname, /etc/resolv.conf, and /etc/nsswitch.conf.

/etc/hostname

1. Edit /etc/hostname:

moxa@MOXA:~# sudo vi /etc/hostname

MOXA

2. Re-configure the hostname.

moxa@MOXA:~# sudo /etc/init.d/hostname.sh start

3. Check the new hostname.

moxa@MOXA:~# hostname

/etc/resolv.conf

This is the most important file that you need to edit when using DNS. For example, before using # ntpdate

time.stdtime.gov.tw 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 (assuming the DNS

server’s IP address is 168.95.1.1): nameserver 168.95.1.1

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
