============
**nntptest**
============
Interactive NNTP test program
Synopsis
========
.. parsed-literal::
**nntptest** [ **-t** *keyfile* ] [ **-p** *port* ] [ **-m** *mechanism* ] [ **-a** *userid* ]
[ **-u** *userid* ] [ **-k** *num* ] [ **-l** *num* ] [ **-r** *realm* ] [ **-f** *file* ]
[ **-n** *num* ] [ **-s** ] [ **-c** ] [ **-i** ] [ **-v** ] [ **-o** *option*\ =\ *value* ] *hostname*
Description
===========
**nntptest** is a utility that allows you to authenticate to a
NNTP server and interactively issue commands to it. Once
authenticated you may issue any NNTP command by simply typing it in.
It is capable of multiple SASL authentication mechanisms and handles
encryption layers transparently. This utility is often used for testing
the operation of an nntp server. Also those developing NNTP clients
find it useful.
Options
=======
.. program:: nntptest
.. option:: -t keyfile
Enable TLS. *keyfile* contains the TLS public and private keys.
Specify **""** to negotiate a TLS encryption layer but not use TLS
authentication.
.. option:: -p port
Port to connect to. If left off this defaults to **nntp** as
defined in ``/etc/services``.
.. option:: -m mechanism
Force **nntptest** to use *mechanism* for authentication. If not
specified, the strongest authentication mechanism supported by the
server is chosen. Specify *login* to use the LOGIN command instead
of AUTHENTICATE.
.. option:: -a userid
Userid to use for authentication; defaults to the current user.
This is the userid whose password or credentials will be presented
to the server for verification.
.. option:: -u userid
Userid to use for authorization; defaults to the current user.
This is the userid whose identity will be assumed after
authentication.
.. Note::
This is only used with SASL mechanisms that allow proxying
(e.g. PLAIN, DIGEST-MD5).
.. option:: -k num
Minimum protection layer required.
.. option:: -l num
Maximum protection layer to use (**0**\ =none; **1**\ =integrity;
etc). For example if you are using the KERBEROS_V4 authentication
mechanism specifying **0** will force imtest to not use any layer
and specifying **1** will force it to use the integrity layer. By
default the maximum supported protection layer will be used.
.. option:: -r realm
Specify the *realm* to use. Certain authentication mechanisms
(e.g. DIGEST-MD5) may require one to specify the realm.
.. option:: -f file
Pipe *file* into connection after authentication.
.. option:: -n num
Number of authentication attempts; default = 1. The client will
attempt to do SSL/TLS session reuse and/or fast reauth
(e.g. DIGEST-MD5), if possible.
.. option:: -s
Enable NNTP over SSL (nntps).
.. option:: -c
Enable challenge prompt callbacks. This will cause the OTP
mechanism to ask for the the one-time password instead of the
secret pass-phrase (library generates the correct response).
.. option:: -i
Don't send an initial client response for SASL mechanisms, even if
the protocol supports it.
.. option:: -v
Verbose. Print out more information than usual.
.. option:: -o option=value
Set the SASL *option* to *value*.
