in reply to Re^10: expect.pm header
in thread expect.pm header

I believe I know what you are looking for. I am not sure what you are currently seeing. Once I know that, I can make a suggestion for how to move forward. With the code that you showed, I would expect that the log file contains:

============ system ============ bla bla bla ============ system ============ bla bla bla ============ system ============ bla bla bla

Is that what you are currently seeing? If so, then I can definitely tell you how to correct the headers. If not, then we need to figure out why no headers are showing up in your log file.

    Thank you I am very humbled for your help its very appreciated. I have my script pointing to one remote solaris 10 server for testing and this is what I see first in debug turned on to my screen and after that this is what I see in my log file.

    First is my output to my screen from debugging.

      Thank you for the output. That makes things much clearer.

      I suspect the ^M were always there, but since all of the lines had them, vi assumed DOS line endings and suppressed them. But, once you added the header with only the line feed, it thought it had unix line endings and showed all of the ^M's. If I am correct, the solution is to replace \n in the header with \r\n like this

      my $header = "\r\n\r\n======= system =======\r\n";

      To get the word "system" change to the actual system name in the log file, replace the line

      $ssh->print_log_file($header);
      with
      my $my_header = $header; $my_header =~ s/system/$system/; $ssh->print_log_file($my_header);

      I hope this helps. Let me know what happens.

        I put in my script as you suggested but I got an error, I am not sure where to place your suggestions in my script

        This is my error on my screen

        perl tester-a.pl syntax error at tester-a.pl line 12, near "$header my " Global symbol "@servers" requires explicit package name at tester-a.pl + line 12. Global symbol "@servers" requires explicit package name at tester-a.pl + line 18. Execution of tester-a.pl aborted due to compilation errors.

        For reference this how I placed it in my script your suggestions

        #!/usr/bin/perl -w use warnings; use strict; use Expect; my $filename = "/var/tmp/expect_script.log"; my $header = "\r\n\r\n======= system =======\r\n"; my $timeout = 60; my $my_header = $header my @servers = qw( remotehost ); for my $server (@servers) { # do your thing with $server change_password($server); } sub change_password { my $system = shift; my $ssh = Expect->new('ssh amagana@' . $system); $ssh->debug(1); $ssh->log_file("$filename"); $my_header =~ s/system/$system/; $ssh->print_log_file($header); $ssh->expect ( $timeout, [ qr/Password:/], [ qr/Are you sure you want to continue connecting \(yes\/no\)?/] ); if ($ssh->match() =~ m/Are you sure you want to continue connecting \( +yes\/no\)?/ ) { $ssh->send("yes\r"); } elsif ($ssh->match() =~ m/Password:/ ) { $ssh->send("mycurrentpassword\n"); } $ssh->expect(60, '$'); $ssh->send("su - root\n"); $ssh->expect(60, 'Password:'); $ssh->send("rootpassword\n"); $ssh->expect(60, '#'); $ssh->send("hostname\n"); $ssh->expect(60, '#'); $ssh->send("uptime\n"); $ssh->expect(60, '#'); $ssh->send("passwd amagana\n"); $ssh->expect(60, 'New Password:'); $ssh->send("mynewpassword\n"); $ssh->expect(60, 'Re-enter new Password:'); $ssh->send("mynewpassword\n"); $ssh->expect(60, '#'); $ssh->send("exit\n"); $ssh->expect(60, '$'); $ssh->send("exit\n"); $ssh->close(); }
