i make a newsimple services file,and i can run inetd.

this is my services file:

<div class='quotetop'>quote

--- quote end ---

--- quote start ---

ftp-data 20/tcp

ftp 21/tcp

telnet 23/tcp

uptime 24/tcp

http 80/tcp

--- Quote End ---

but I can&#39;t use telnet on a pc to connect my board.

it saied:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

telnetd:all network ports in use.[/b]

--- Quote End ---

netstat

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

tcp 0 0 218.192.170.81:telnet 218.192.170.250:3520 TIME_WAIT[/b]

--- Quote End ---

and i run ps

ps

i can see "inetd",but i can&#39;t see telnetd.

why it say "telnetd:all network ports in use."

how can i do?

my inetd.conf file:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

ftp stream tcp nowait root /bin/ftpd

telnet stream tcp nowait root /bin/telnetd

uptime stream tcp nowait root cat /proc/uptime /etc/issue[/b]

--- Quote End ---

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

devpts /dev/pts devpts defaults,gid=5,mode=620 0 0[/b]

--- Quote End ---

<div align='right'><{post_snapback}> (index.php?act=findpost&pid=14160)</div>

[/b]

after some google search, you may need these in uClinux-dist-test menuconfig, clean and rebuild

  telnetd 
        telnetd does not use openpty() (NEW)  

you should config kernel, with,

Device Drivers --> Character devices -->

[*] Legacy (BSD) PTY support

(10) Maximum number of legacy PTY in use

you should use inetd from ~/apps/inetd,

and use telnetd from ~/uClinux-dist-test/user/telnetd

found out myself,

all is working but I started the telnetd the wrong way.

telnetd should be started by inetd and not by invoking /bin/telnetd &.

telnetd only shows up in the process list when a session is started from a remote host.
