DA-710 Series Linux
Managing Communications
3-7
For example, use the following commands to set
/dev/ttyM0
to RS-422:
MOXA:~# setinterface /dev/ttyM0 2
MOXA:~# setinterface /dev/ttyM0
Now setting is RS422 interface.
MOXA:~#
Telnet/FTP Server
In addition to supporting Telnet client/server and FTP client/server, the DA-710-LX also supports SSH and sftp
client/server. To enable or disable the Telnet/ftp server, you need to edit the file
/etc/inetd.conf
.
1.
Mount the root file system with write permission.
MOXA:~# mount -o remount,rw /dev/hda1 /
2.
Type
# cd /etc
to change the directory.
MOXA:~# cd /etc
3.
Type
# vi inetd.conf
to edit the configuration file.
MOXA:/etc# vi 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. For example,
to disable the
FTP
server, use the following commands:
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
After you finish writing or modifying the code, remember to execute “umount /” to change the root directory
back to Read-only mode.
MOXA:~# umount /
