This is an example of how Expect.pm and clogin can be used together:

#! /usr/bin/perl -w use warnings; use diagnostics; use strict; use Expect qw(expect); use Carp; scalar @ARGV or croak "usage: $0 host1..."; my $session = Expect->spawn( 'clogin', $ARGV[0] ); if ( exists $ENV{'exp_internal'} ) { $session->exp_internal(1) } $session->log_stdout(1); sub expect_send { my $pattern = shift; my $command = shift; my $ret = $session->expect( 30, [ '-re', $pattern => sub { $_[0]->send("$command\n") } ], @_, [ timeout => sub { croak 'Timeout' } ], [ eof => sub { croak 'EOF (clogin exited unexpectedly)' } +], ); croak 'Nothing matched, not even timeout, died' if not defined $ret; return $ret; } expect_send qr/#/, 'show clock'; expect_send qr/#/, 'show logging'; $session->expect( 30, [ '-re', qr/Log Buffer \(\d+ bytes\)/i => sub { $session->match() =~ /\((\d+) bytes\)/i; print "\n\n* Found logging buffer size is $1 bytes *\n\n"; if ( $1 < 8192 ) { expect_send qr/#/, 'configure terminal'; expect_send qr/\(config\)#/i, 'logging buffered 8192'; expect_send qr/\(config\)#/i, 'end'; expect_send qr/#/, 'write memory'; } } ], ); expect_send qr/#/, 'exit'; $session->soft_close;

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
