Telnet / FTP 
In addition to supporting Telnet client/server and FTP client/server, the W311/321/341 also 
support 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 W311/321/341 support 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. 
Web Service—Apache 
The Apache web server’s main configuration file is 
/etc/apache/conf/httpd.conf
, with the 
default homepage located at 
/home/httpd/htdocs/index.html
. Save your own homepage to the 
following directory:
