Telnet "connection closed by foreign host" issue and ftpd not reachable

Hi,

I am currently working on a sbc6000x board (armv5) with busybox on it and would like the run a Telnet daemon and ftp daemon on it.

My inetd.conf file is :

Code:

#<service_name>    <sock_type>    <proto>    <flags> <user>     <server_path>     <args> 

ftp            stream        tcp        nowait    root    /usr/sbin/ftpd -wS /etc
telnet            stream        tcp        nowait    root    /usr/sbin/telnetd

I checked, the symlink are in /usr/sbin.

hosts.deny is empty and there is no firewall on each machine.

When trying to Telnet to my target i have the issue :

Code:

:~# telnet 10.2.29.201 23
Trying 10.2.29.201...
Connected to 10.2.29.201.
Escape character is '^]'.
Connection closed by foreign host.

Same thing when trying "Telnet localhost 23" on the board.

When trying to connect to the ftp server i have the message :

Code:

504 Gateway Timeout
Gateway timeout expired while waiting for server response.

Does anyone have an idea on what i could do ?

Kind regards

What's output of "netstat -l"? Is telnet and ftp port listened?

make sure these services are running
potmap
xinetd
telnetd
any way telnet is very insecure
use ssh
And what ftp service u r using?
