I you use cpio, symbolic links and empty dirs can be copied. Strangely, as I recall, sometimes cp -r and rcp -r use cpio, and cp -rp says it will preserve links. Breaking the compression out from the ssh2 allows more CPUs to be utilized pipeline parallel.
Hi DGPickett,
I have tried the code but didnt work, actually ssh part does not work, i had a different error when i tried ssh (rather than ssh2 as its not supported)
Hi,
Is there a limit to the number of symbolic links you can have?
I tried to vi the symbolic link relating to a file and got the following error:
"filename" Too many levels of symbolic links
There is only one symbolic link to one file in this case, but there are >2000 other links to... (2 Replies)

I am linking a directory as follows:
ln -sf /home/xxx/userid/real_files/* /home/xxx/userid/linked_files
This gives me symbolic links for all the files in the real_files directory in the linked_files directory. My question is, if I go and remove a file in the real_files directory and then go... (1 Reply)
I need to copy a directory from a production system to a test system on the same Aix server. However I need to ensure that the soft links are preserved as part of the copy ( therefore I guess the cp command is not the way to go )
What command can I use in Aix to achieve this copy ?
thanks in... (2 Replies)
Hi Guys...
I want to create a link using ln -s for a directory that does not exist on the box.
How do I do that?
I had some files from Box A directory /d1/u01 and I copied the files across to another Box lets say Box B on directory /d2/u02.
Now I want a link so that this path /d1/u01... (2 Replies)
Hi all,
I have scoured the entire forum for this but to no avail unfortunately. Basically, I would like to remove my symbolic link from my folder name i.e.
foldername -> /a/b/c/d/f
where f is indeed a folder. I have tried rmdir but this does not work and in actual fact deletes the... (4 Replies)
Hi,
I have a file with more than 1 layers of soft links for it. For ex.
ls -la .profile
.profile@ -> /home/act/.profile_abc

/home/act/.profile_abc@ -> .profile_final
I want to get the name of the last file (i.e. .profile_final) when I refer to .profile using shell script. I... (2 Replies)
Net::OpenSSH::Compat::SSH2(3pm) User Contributed Perl Documentation Net::OpenSSH::Compat::SSH2(3pm)NAME
Net::OpenSSH::Compat::SSH2 - Net::OpenSSH adapter for Net::SSH2 API compatibility
SYNOPSIS
use Net::OpenSSH::Compat::SSH2 qw(:supplant);
use Net::SSH2;
my $ssh2 = Net::SSH2->new;
$ssh2->connect('host');
$ssh2->auth_publickey("jsmith",
"/home/jsmith/.ssh/id_dsa.pub",
"/home/jsmith/.ssh/id_dsa");
my $c = $ssh2->channel;
$c->exec("ls");
print while <$c>;
$c->close;
print "exit status: ", $c->exit_status, "
";
DESCRIPTION
This module implements Net::SSH2 API on top of Net::OpenSSH.
After the module is loaded as...
use Net::OpenSSH::Compat::SSH2 qw(:supplant);
it will supplant the Net::SSH2 module as if it was installed on the machine and use Net::OpenSSH under the hood to handle SSH operations.
Most programs using Net::SSH2 should continue to work without any change.
Setting defaults
The hash %Net::OpenSSH::Compat::SSH2::DEFAULTS can be used to set default values for Net::OpenSSH and other modules called under the hood
and otherwise not accesible through the Net::SSH2 API.
The entries currently supported are:
connection => [ %opts ]
Extra options passed to "Net::OpenSSH::new" constructor.
Example:
$Net::OpenSSH::Compat::SSH2::DEFAULTS{connection} =
[ ssh_path => "/opt/SSH/bin/ssh" ];
channel => [ %opts ]
Extra options passed to "Net::OpenSSH::open_ex" method.
sftp => [ %opts ]
Extra options passed to "Net::SFTP::Foreign::new" constructor.
$Net::OpenSSH::Compat::SSH2::DEFAULTS{connection} =
[ read_ahead => 128 * 1024, queue_size => 20 ];
BUGS AND SUPPORT
This is a work in progress.
Besides that, there are some functionality of Net::SSH2 that can not be emulated with Net::OpenSSH. Fortunatelly, the missing bits are
rarely used so probably you may not need them at all.
Specifically, the return values from the "$ssh2->method($ATTR)" are not real but faked ones. "auth_list" return value is also faked.
Anyway, if your Net::SSH2 script fails, fill a bug report at the CPAN RT bugtracker
(https://rt.cpan.org/Ticket/Create.html?Queue=Net-OpenSSH-Compat <https://rt.cpan.org/Ticket/Create.html?Queue=Net-OpenSSH-Compat>) or just
send me an e-mail with the details.
Include at least:
1 - The full source of the script
2 - A description of what happens in your machine
3 - What you thing it should be happening
4 - What happens when you use the real Net::SSH2
5 - The version and name of your operating system
6 - The version of the OpenSSH ssh client installed on your machine ("ssh -V")
7 - The Perl version ("perl -V")
8 - The versions of the Perl packages Net::OpenSSH, IO::Pty and this Net::OpenSSH::Compat.
