Edit /etc/inetd.conf
adding following line on the file;
Code:
poppassd stream tcp nowait root /usr/sbin/tcpd /usr/sbin/poppassd

$ sudo /etc/init.d/inetd restart
Code:
 * Restarting internet superserver...                                                                                                                   [ OK ]

$ telnet localhost 106
Code:
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
Connection closed by foreign host.

It comes back to the original problem before deleting xinetd.


Quote:
If you are using xinted, you don't add any configuration to xinetd.conf, you create a control file in /etc/xinetd.d (I think that is the correct directory, but since I don't have it I cannot check).
I already deleted xinetd. I won't use it unless necessary.

Note that it said "Connection closed" not "Connection refused".

Does netstat say anyone is listening on 106?

Code:
netstat -an | grep LISTEN

Also try without tcp wrappers first:

Code:
poppassd stream tcp nowait root /usr/sbin/poppassd in.poppassd

Yup, something's there. All you need to find out is what it is.

Is there anything in the syslog?

Can you confirm you can execute the command line indicated in /etc/inetd.conf for port 106 from the command prompt?

Sorry I don't follow.

$ cat /etc/pam.d/poppassd
Code:
#
# The PAM configuration file for the `poppassd' daemon
#

@include common-auth
@include common-password

Whether putting the line
Code:
poppassd stream tcp nowait root /usr/sbin/poppassd

on the file /etc/pam.d/poppassd ?


Performed following steps;
$ cat /etc/inetd.conf
Code:
poppassd stream tcp nowait root /usr/sbin/poppassd

$ sudo nano /etc/inetd.conf
Code:
satimis@mail:~$ sudo /etc/init.d/inetd restart
 * Restarting internet superserver...                                       [ OK ]

$ telnet localhost 106
Code:
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
Connection closed by foreign host.

same result
