7.3. Telnet & SSH Service
Telnet and SSH can be used to remote login to the DCU. SSH uses encryption transportation, and the transportation on
Telnet is only by ACSII code.
You can turn on those services on the /etc/inetd.conf to make them as auto-run daemon after booting.
# vi /etc/inetd.conf
ftp stream tcp nowait root /usr/local/sbin/pure-ftpd pure-ftpd -H &
telnet stream tcp nowait root /usr/sbin/telnetd telnetd -i
ssh stream tcp nowait root /usr/bin/dropbear dropbear -i
#www stream tcp nowait root /usr/sbin/httpd httpd -i -h /home/htdocs
The default port of telnet service will be port 23.
The default port of SSH service will be port 22.
You can use PuTTY or other terminal programs to login DCU via those protocols.
Figure 15, Use Putty to create a telnet or SSH connection.
