       nntptest - interactive NNTP test program


       nntptest [ -t keyfile ] [ -p port ] [ -m mechanism ]
                [ -a userid ] [ -u userid ] [ -k num ] [ -l num ]
                [ -r realm ] [ -f file ] [ -n num ] [ -s ] [ -c ]
                [ -i ] [ -o option=value ] [ -v ] hostname


       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  a  nntp
       server. Also those developing NNTP clients find it useful.


       -t keyfile
              Enable  TLS.   keyfile  contains  the  TLS  public and private keys.  Specify "" to
              negotiate a TLS encryption layer but not use TLS authentication.

       -p port
              Port to connect to. If left off this defaults to nntp as defined in /etc/services.

       -m mechanism
              Force nntptest to use mechanism for authentication. If not specified the  strongest
              authentication  mechanism  supported  by the server is chosen.  Specify user to use
              the AUTHINFO USER/PASS commands instead of AUTHINFO SASL.

       -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.

       -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).

       -k num Minimum protection layer required.

       -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 nntptest  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.

       -r realm
              Specify the realm to use. Certain authentication mechanisms (e.g.  DIGEST-MD5)  may
              require one to specify the realm.

       -f file
              Pipe file into connection after authentication.

       -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.

       -s     Enable NNTP over SSL (nntps).

       -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).

       -i     Don't send an initial client response for SASL mechanisms,  even  if  the  protocol
              supports it.

       -o option=value
              Set the SASL option to value.

       -v     Verbose. Print out more information than usual.
