       bb-services - Configuration of TCP network services




       bb-services  contains  definitions  of  how bbtest-net(1) should test a
       TCP-based network service (i.e. all common network services except HTTP
       and  DNS).  For each service, a simple dialogue can be defined to check
       that the service is functioning normally, and optional flags  determine
       if  the  service  has  e.g.  a  banner or requires SSL- or telnet-style
       handshaking to be tested.


       bb-services is a text file. A simple service definition  for  the  SMTP
       service would be this:

             send "mail\r\nquit\r\n"
             expect "220"
             options banner

       This  defines  a  service  called  "smtp". When the connection is first
       established, bbtest-net will send the string "mail\r\nquit\r\n" to  the
       service. It will then expect a response beginning with "220".  Any data
       returned by the service (a so-called "banner")  will  be  recorded  and
       included in the status message.

       The full set of commands available for the bb-services file are:

       [NAME] Define  the  name  of  the  TCP  service, which will also be the
              column-name in the resulting display  on  the  test  status.  If
              multiple  tests  share  a  common definition (e.g. ssh, ssh1 and
              ssh2 are tested identically), you may list  these  in  a  single
              "[ssh|ssh1|ssh2]"  definition, separating each service-name with
              a pipe-sign.

       send STRING

       expect STRING
              Defines the strings to send to the service after a connection is
              established,  and the response that is expected. Either of these
              may be omitted, in which case bbtest-net(1) will simply not send
              any data, or match a response against anything.

              The  send-  and  expect-strings  use  standard escaping for non-
              printable characters. "\r" represents a  carriage-return  (ASCII
              13),  "\n"  represents a line-feed (ASCII 10), "\t" represents a
              TAB (ASCII 8).  Binary data is input as "\xNN" with NN being the
              hexadecimal value of the byte.

       port NUMBER
              Define  the  default  TCP  port-number  for  this service. If no
              portnumber is defined, bbtest-net(1) will attempt to lookup  the
              portnumber in the standard /etc/services file.

       options option1[,option2][,option3]
              Defines test options. The possible options are
                 banner - include received data in the status message
                 ssl - service uses SSL so perform an SSL handshake
                 telnet - service is telnet, so exchange telnet options
