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:
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
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.
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.
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
