12 . You'd like to communicate with another host or device via a
13 TELNET port and you'd like some specialized routines to help you
14 login and do other interactive things.
16 . You're not familiar with sockets and you want a simple way to
17 make client connections to TCP services.
19 . You want to be able to specify your own time-out while
20 connecting, reading, and writing.
22 . You're communicating with an interactive program at the other
23 end of some socket or pipe and you want to wait for certain
30 . In the CPAN directory: modules/by-module/Net/
32 . To find a CPAN site near you see http://cpan.perl.org/SITES.html
38 . Perl Version 5.002 or later
40 . A MS-Windows machine requires Perl version 5.003_07 or later
42 . No other modules are required that don't already come with a
43 standard distribution of Perl.
49 Net::Telnet allows you to make client connections to a TCP port
50 and do network I/O, especially to a port using the TELNET
51 protocol. Simple I/O methods such as print, get, and getline are
52 provided. More sophisticated interactive features are provided
53 because connecting to a TELNET port ultimately means communicating
54 with a program designed for human interaction. These interactive
55 features include the ability to specify a timeout and to wait for
56 patterns to appear in the input stream, such as the prompt from a
59 Here's an example that prints who's logged-on to the remote host
60 sparky. In addition to a username and password, you must also
61 know the user's shell prompt, which for this example it's bash$
64 $t = new Net::Telnet (Timeout => 10,
65 Prompt => '/bash\$ $/');
67 $t->login($username, $passwd);
68 @lines = $t->cmd("who");

72 documentation for the section "What To Know Before Using".

84 User documentation in POD format is contained within the module
85 source (i.e. the .pm file). Installing using "make install"
86 places this documentation in a man page in the perl library under
87 the directory "man/man3".
89 To nicely format the documentation for printing, you may use
90 "groff" to convert to postscript. Groff is available under
91 the GNU General Public License (GPL) and is installed on most
94 pod2man Net/Telnet.pm | groff -man -Tps > Net::Telnet.ps
100 To install, cd to the directory containing the unpacked
101 distribution and do one of the following:
103 a. Create a makefile by running Makefile.PL using the perl
104 program into whose library you want to install and then run
112 b. To install into a private library, for example your home
116 INSTALLSITELIB=$HOME/lib/perl \
117 INSTALLMAN3DIR=$HOME/lib/perl/man/man3
122 c. Alternatively, you can just copy or move Telnet.pm
123 from the distribution into a directory named Net/ in the Perl
124 library. You can then manually build the documentation using
