Dear Philipp,
Thanks for your suggestion. I enabled to support standalone telnetd in
busybox and add "-i" in inetd.conf as:
telnet stream tcp nowait root /usr/sbin/telnetd telnetd -i
or even
telnet stream tcp nowait root /usr/sbin/telnetd telnetd -i -l /bin/ash
When I telnet the board from a PC, it shows:
# telnet 192.168.0.4 (board IP)
Trying 192.168.0.4...
connected to 192.168.0.4.
Escape character is '^]'
Then the cursor stops and there is no login interface. If I kill the
"telnetd -i" process from the board, then the following part shows as:
Connection closed by foreign host.
It is still not correct. But it seems that the board could react the telnet
command from outside. How can it show the login interface?
Thanks for your telling.

Ming

Did you enable:
���[*] Support standalone telnetd (not inetd only) ???
if you did add a -i to the inetd.conf and try again
