SYNOPSIS

$BBHOME/etc/bb-services

DESCRIPTION

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.

FILE FORMAT

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

   [smtp]

      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
