DESCRIPTION

35       Use this program to help write reusable Net::Appliance::Session
36       scripts, play them back, and also to more easily connect to network
37       devices.
38
39       •   Start a connection to a network device using CLI switches, and
40           prompts for credentials. This is easier than writing short Perl
41           programs.
42
43       •   Record a set of commands issued to one network device into a
44           command log, then replay that log against other devices ("-R -l
45           <log>" and "-P -l <log>").
46
47       •   Record a session and produce a Perl script which when run, replays
48           the session to the same host, or overridable to other devices ("-R
49           -s <script>" and then run the script).
50
51       Once connected to the device you can enter any command and it will be
52       run.
53

GENERAL USAGE NOTES

55       The "exit-last" option can be useful for creating a session script
56       which checks for some error condition. Assuming the last command should
57       have no output on success, then the exit status of the script will be
58       non-zero when there's a problem. Use this with "-R" to make a reuseable
59       script.
60
61       To play a script with no output other than that returned from the
62       device in response to sent commands, use the switch combination
63       "-Bqoz". Note that you will need to be able to login automatically, and
64       RANCID config isn't yet supported.
65
66       If you don't provide a hostname or IP then the script goes into a loop
67       waiting for the hostname on standard input. This way, you can pipe a
68       list of device names to the script and it will execute the commands on
69       each one.
70
71       In case you didn't know, the library has support for connecting to
72       linux boxes using the "-p bash" setting to chose the Bash shell
73       personality.
74
75       Getting to be a super-user is a little clunky at the moment. I need to
76       work on that a little more. Take care that your scripts don't contain
77       any passwords!

SPECIAL FEATURES

80       The methods of Net::Appliance::Session are available by using the
81       command "!s <method-name>". The best use of this is to gracefully
82       disconnect, by issuing:
83
84        !s close
85
86       You can also enter the command "!m" to see a list of available Macros.
87       If you don't know what a Macro is, please move a long, there's nothing
88       to see here.  You run a Macro with the "!m <macro-name> [params]"
89       command.
