I've uploaded Net::Telnet version 3.01 to CPAN. Look for it at a CPAN
site near you.
$CPAN/modules/by-module/Net/Net-Telnet-3.01.tar.gz
This version fixes a bug in cmd() where the first line of output
would sometimes be removed.
The routine fhopen() now works with uni-directional pipes like STDIN.
You can use this feature with any perl filehandle to wait for patterns
to appear or to read using a timeout.
See the file ChangeLog in the distribution for a complete list of
changes.
The latest Perl Journal contains an article on about Net::Telnet.
Buying "The Perl Journal" is one way to help promote Perl - it's also
cool :-)
For those unfamiliar with Net::Telnet, here's some text from the
README file:
Net::Telnet, version 3.01
What's In It For You
--------------------
. You'd like to communicate with another host or device via a
TELNET port and you'd like some specialized routines to help you
login and do other interactive things.
. You're not familiar with sockets and you want a simple way to
make client connections to TCP services.
. You want to be able to specify your own time-out while
connecting, reading, and writing.
. You're communicating with an interactive program at the other
end of some socket or pipe and you want to wait for certain
patterns to appear.
Archive Location
----------------
. In the CPAN directory: modules/by-module/Net/
. To find a CPAN site near you see
http://cpan.perl.org/SITES.html
Prerequisites
-------------
. Perl Version 5.002 or later
. A Windows 95/NT machine requires Perl version 5.003_07 or later
. No other modules are required that don't already come with a
standard distribution of Perl.
Description
-----------
Net::Telnet allows you to make client connections to a TCP port
and do network I/O, especially to a port using the TELNET
protocol. Simple I/O methods such as print, get, and getline are
provided. More sophisticated interactive features are provided
because connecting to a TELNET port ultimately means communicating
with a program designed for human interaction. These interactive
features include the ability to specify a timeout and to wait for
patterns to appear in the input stream, such as the prompt from a
shell.
Here's an example that prints who's logged-on to the remote host
sparky. In addition to a username and password, you must also
know the user's shell prompt, which for this example is bash$
use Net::Telnet ();
$t = new Net::Telnet (Timeout => 10,
Prompt => '/bash\$ $/');
$t->open("sparky");
$t->login($username, $passwd);
@lines = $t->cmd("/usr/bin/who");
print @lines;
See the user documentation for more examples.
This is an alpha version - meaning that the interface may change
in future versions. Contact me, Jay Rogers <
[email protected]>, if you
find any bugs or have suggestions for improvement.
Documentation
-------------
User documentation in POD format is contained within the module
source (i.e. the .pm file). Installing using "make install"
places this documentation in a man page in the perl library under
the directory "man/man3".
