| Summary : Net-SSH-Perl - Perl client interface to SSH
|
Description :
I< Net::SSH::Perl> is an all-Perl module implementing an SSH
(Secure Shell) client. It is compatible with both the SSH-1 and
SSH-2 protocols.
I< Net::SSH::Perl> enables you to simply and securely execute commands
on remote machines, and receive the STDOUT, STDERR, and exit status
of that remote command. It contains built-in support for various
methods of authenticating with the server (password authentication,
RSA challenge-response authentication, etc.). It completely implements
the I/O buffering, packet transport, and user authentication layers
of the SSH protocol, and makes use of external Perl libraries (in
the Crypt:: family of modules) to handle encryption of all data sent
across the insecure network. It can also read your existing SSH
configuration files (F< /etc/ssh_config>, etc.), RSA identity files,
DSA identity files, known hosts files, etc.
One advantage to using I< Net::SSH::Perl> over wrapper-style
implementations of ssh clients is that it saves on process
overhead: you no longer need to fork and execute a separate process
in order to connect to an sshd. Depending on the amount of time
and memory needed to fork a process, this win can be quite
substantial; particularly if you\'re running in a persistent
Perl environment (I< mod_perl>, for example), where forking a new
process is a drain on process and memory resources.
It also simplifies the process of using password-based authentications;
when writing a wrapper around I< ssh> you probably need to use
I< Expect> to control the ssh client and give it your password.
I< Net::SSH::Perl> has built-in support for the authentication
protocols, so there\'s no longer any hassle of communicating with
any external processes.
The SSH2 protocol support (present in I< Net::SSH::Perl> as of version
1.00) is compatible with the SSH2 implementation in OpenSSH, and should
also be fully compatible with the \"official\" SSH implementation. If
you find an SSH2 implementation that is not compatible with
I< Net::SSH::Perl>, please let me know (email address down in
I< AUTHOR & COPYRIGHTS>); it turns out that some SSH2 implementations
have subtle differences from others. 3DES (C< 3des-cbc>), Blowfish
(C< blowfish-cbc>), and RC4 (C< arcfour>) ciphers are currently
supported for SSH2 encryption, and integrity checking is performed
by either the C< hmac-sha1> or C< hmac-md5> algorithms. Compression, if
requested, is limited to Zlib. Supported server host key algorithms
are C< ssh-dss> (the default) and C< ssh-rsa> (requires I< Crypt::RSA>);
supported SSH2 public key authentication algorithms are the same.
If you\'re looking for SFTP support, take a look at I< Net::SFTP>,
which provides a full-featured Perl implementation of SFTP, and
sits on top of I< Net::SSH::Perl>. SFTP requires the usage of the
SSH2 protocol.
