Hiya, I would like to know if you have in mind to add the behaviour to change the SSH Options, i.e. giving access to @SSH_Options, or giving a method for accessing to this variable. * Net::SSH 0.09 * Perl 5.8.8 * RH 5 Cheers, Carlos -- Carlos Fuentes Bermejo <carlos.fuentes@rediris.es> Security Specialist - IRIS-CERT RedIRIS/Red.es Tel: 91 212 76 20/25 Ext: 5583 www.rediris.es - http://www.rediris.es/cert PGP key: http://www.rediris.es/keyserver

I do not anticipate adding features or doing significant future development on the module. The module could really use a maintainer with enough time to at least review and apply more patches. Or the module should just be deprecated in favor of Net::SSH::Expect or made into an ::Any style compatibility wrapper that uses whatver implementation is avaialble (Net::SSH2, Net::SSH::Perl or shelling out like the module does now).

I too would like to set arbitrary ssh options. My use case is that I am using ssh_cmd to do something like this: ssh $src_host "ssh $dst_host 'tar xvpi -C $dst_dir' < '$src_file'" I've found that, with the default Net::SSH options, if I kill the script that made the ssh_cmd call then the remote ssh and tar processes keep running. "-T" is the culprit. I need to set "-t -t". I hacked it by adding code to my module that calls ssh_cmd as follows: @Net::SSH::ssh_options = grep(!/-T/, &Net::SSH::_ssh_options); push @Net::SSH::ssh_options, '-t', '-t'; However, it would be preferable to actually surface these options through a proper API, rather than poking around in Net::SSH internals. I've sent a mail to Ivan offering to take on co-maintainer for this module and would be happy to add some mechanism to allow setting of arbitrary ssh options. R.

The actual code of Net::SSH hasn't been updated on over 7 years. It may be better at this point to focus on more modern alternatives, such as Net::OpenSSH or the modules listed in the SEE ALSO section. I've mostly switched to Net::OpenSSH myself. If none of the other modules fit your needs and you _really_ do want to revive Net::SSH, I guess so.. I would be curious to know why none of the other modules worked out. Ivan

Net::SSH just worked for me - with one niggling problem that I fixed by hacking the @ssh_options array as listed above. Net::SSH::Perl wouldn't install easily on CentOS 5.6 (ie. yum install perl-Net-SSH-Perl didn't work) Net::OpenSSH is rather implementation-specific. I don't have many non-OpenSSH boxes, but I have a couple. I need to work on all platforms. I didn't bother trying it for that reason. I don't actually need to add/change anything about Net::SSH at this stage - it's working for me with the above hack. I just thought it might be useful to others to add a few changes. R.
