       nessus-adduser - add a user in the nessusd userbase




       The Nessus Security Scanner comes with its own user base which contains
       the list of who can use the services of nessusd, and  what  restriction
       (or rules) each user has.

       nessus-adduser  is a simple program which will add a user in the proper
       nessusd configuration files, and will send a signal to nessusd if it is
       running to notify it of the changes.

       The program is straightforward and asks for the following items:

       · Login
              the login name of the nessusd user to add

       · Password
              the password that the user will use to connect to nessusd

       · Authentification type
              the authentification method the client will use. The recommended
              method is “cipher”. However, if you compiled nessusd without the
              cipher  support  or  if you are using a Nessus client which does
              not support the cipher layer, you’ll have to use “plaintext”

       · Rules
              the set of rules to apply to the user. See below.


       Each user has his own set of rules. Rules  are  here  to  restrict  the
       rights  of  the  users. For instance, you can add user “joe” so that he
       can only test the host “”, whereas you can add user “bob” so
       that he can test whatever IP address he wishes.

       Each  rule  fits  on  one  line. A user can have an unlimited amount of
       rules (and can even have no rule at all).

       The syntax is:
              accept|deny ip/mask
              default accept|deny

       Where mask is the CIDR netmask of the rule.

       The default statement must be the last rule and defines the  policy  of
       the user.

       The  following  rule  set  will  allow the user to test, and, but nothing else:
              default deny

       The following rule set will allow the user to test whatever  he  wants,
       except the network
              default accept

       The  keyword client_ip has been defined, and is replaced at run time by
       the IP address of the nessusd user. For  instance,  if  you  want  your
       users  to  be  able  to only be able to scan the system they come from,
       then you want them to have the following ruleset:
              accept client_ip
              default deny

       nessus-adduser creates temporary files in $TMPDIR/.  If  this  variable
       is  not  set,  then  it  will use /var/tmp which may be a security risk
       depending of your configuration.

       If you set your TMPDIR variable to /tmp, then you are in trouble.
