Net::OpenSSH across fork & exec

dwalin has asked for the wisdom of the Perl Monks concerning the following question:

Hello wise brethren, calling for your aid again. The question is simple this time: is there a way to pass Net::OpenSSH master connection socket to exec()'d process? Something like this:

#!perl -w
use Net::OpenSSH;

my $ssh = Net::OpenSSH->new("hostname");

if (my $pid = fork) {
 # wait for children, do something
} elsif ($pid == 0) {
 exec "another_perl_script";
}
__END__

another_perl_script:
#!perl -w

use Net::OpenSSH;

# do something to retrieve master connection
my $ssh = Net::OpenSSH->...

$ssh->system("remote command");

...

Perhaps I wasn't attentive enough but I can't find a way to pass master socket to new(). I can pass it the same control directory but that results in Net::SSH creating another master connection.

Thanks in advance!

Regards,
Alex.

I have added the feature to reuse an external OpenSSH master connection to the latest development version (1.51_05): `my $ssh = Net::OpenSSH->new($host, reuse_master => 1, ctl_path => $from_first_script);` [download] Though, I don't really like calling the new option "reuse_master", I am thinking of changing it to "external_master".

Thanks for such quick reply. I have removed my previous suggestion, since it appears that you have already did that. :) Regards, Alex.	[reply]

yes, now, it works as follows: `#!perl -w use Net::OpenSSH; my $ssh = Net::OpenSSH->new("hostname"); if (my $pid = fork) { # wait for children, do something } elsif ($pid == 0) { exec "another_perl_script", $ssh->get_ctl_path; } __END__ another_perl_script: #!perl -w use Net::OpenSSH; my $ssh = Net::OpenSSH->new($host_or_some_dummy_value, ctl_path => $ARGV[0], reuse_master => 1); $ssh->system("remote command");` [download]	[reply] [d/l]
