How to startup telnet daemon?

I have startup inited sucessfully, but I cann’t start up telnetd using command “telnetd”.

i guess your started inetd. Check if the telnet line in inetd.conf is not comment.
The network itself is up? Firewall within the routing is open too?

Inetd will start telnetd when it receives a connection requestion on port 23. To start it manually I think you need to use -debug flag.

I have finished this problem with next command:
#inetd &
#ftp &”

And then I passwd a user “ntuser”, that is very strange, my os have not this user.and modifide the file “/etc/passwd”:
“ntuser : x : 100 : 100 : : /home/ntuser :/bin/sh”
