Can't into my server ?

[Tommy Wu <newsletter@teatime.com.tw>]

Hi!

   I just install a new woody linux box.
   But I found that I can't telnet into this box even in localhost.
   I can use any other protocol to this server, like ssh, ftp, www... but
   only telnet can't work.
   
   when I try to telnet localhost, I got the message like:

tommywu@hisdb:~$ telnet localhost
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Debian GNU/Linux 3.0 woody hisdb.tahsda.org.tw
Connection closed by foreign host.
tommywu@hisdb:~$

    the log in syslog/daemon.log like:
    
Aug 25 13:03:15 hisdb in.telnetd[3817]: connect from 127.0.0.1

   there is no any other log found.
   
   I also try to running another telnetd in debug mode, as 

/usr/sbin/in.telnetd -debug 99 -D report

   and try to telnet localhost 99 again, got:
   
tommywu@hisdb:~$ telnet localhost 99
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

    I also has more than 3 linux server runnig the same version, but there is no such
    problem.... Is the a configure problem or something I missing ?

    Any suggestion ? Thanks a lots.
