"Can anyone tell me how to supply password using DSA or RSA keys in Net::SSH module." The Net::SSH documentation covers this topic in the FAQ section. Please read the documentation. "Note: Since i am using Windows platform i can't use Net::SSH::Perl or Net::SSH::W32Perl modules." If your issue is that you do not have a compiler, the README for Net::SSH::W32Perl states: "NOTE: I've made ppms (binaries) available for this and most of it's required modules at Http://www.soulcage.net/ppds/. The following command should install everything you need. `ppm install --location=http://www.soulcage.net/ppds Net::SSH::W32Perl"` Or you may want to look at Camelpack, a "Windows installer to setup a complete Perl development environment including support for building C/C++ extensions."

Can anyone tell me how to supply password using DSA or RSA keys in Net::SSH module. Note that Net::SSH requires the `ssh` command, so presumably you have cygwin installed and ssh installed in it. Then, as the manual says, use ssh-keygen. You can find plenty of tutorials describing how to do passwordless logins. Basically you'll append id_rsa.pub or id_dsa.pub (your public key) onto the remote system's .ssh/authorized_keys file (if you have ssh-copy-id, it's even easier). I'm not sure why you say Net::SSH::Perl or Net::SSH::W32Perl won't work because you're on Windows, though.	[reply]

If you have a `ssh` binary on your system that works, and you can log in to the other machine manually, you could use Expect to automate the exact process you'd use as if you where logging in manually.	[reply]

Hey Before writing perl program to access unix system first try to see you can access unix machine using ssh from your command $ prompt..if you were able to access it then you shouldn't have any issues using Net::SSH. DSA or RSA keys is something like public and private keys If I am correct you will supply one key to connect to unix machine and that machine will verify the key you supplied and if its correct then you will be given access to the system its password less authentication Before digging into Net::SSH check to see you are able to access manually Sridhar	[reply]

Hi, Thanks for all your posts. Martin, Net::SSH documentations says just these lines in its documentation. "You don't. Use RSA or DSA keys. See the ssh-keygen(1) manpage" I don't know how to use RSA or DSA keys in Net::SSH module, that's why i posted this query. I have installed Net::SSH::Perl and Net::SSH::W32Perl in my maching using PPM. But, when i try to run using these modules i get the following error message. "The getpwuid function is unimplemented at C:/Perl/site/lib/Net/SSH/Perl.pm line 110." I also suffered in the internet and found out that getpwuid is not implemented for Win32 System. See http://www.perl.com/doc/FAQs/nt/perlwin32faq5.html. I have ssh command in my machine. I have tried connecting the UNIX server manually (i.e. giving the password details manually) and it is working fine. Now, my question is how to connect to UNIX server using Net::SSH module with DSA or RSA keys? Once again, thanks for all your help. Hemaraj	[reply]
