Feb 12, 2016 · Paramiko is an open source Python implementation of the SSHv2 protocol, providing both client and server functionality. Worker function will irst download a private key file from a secured Amazon S3 bucket to the local /tmp folder, and then use that key file to connect to the EC2 instances by using SSH. exec_command has been updated to use that class for its stdin return value. Thanks to Brandon Rhodes for the report & steps to reproduce. [Support] #1311: (for #584, replacing #1166) Add backwards-compatible support for the gssapi GSSAPI library, as the previous backend (python-gssapi) has since become defunct. This change also includes tests ...paramiko是基于Python实现的SSH2远程安全连接,支持认证及密钥方式。可以实现远程命令执行、文件传输、中间SSH代理等功能,相对于Pexpect,封装的层次更高,更贴近SSH协议的功能 ssh = paramiko.

Paramiko, Release New in version 1.1. recv_stderr_ready() Returns true if data is buffered and ready to be read from this channel's stderr stream. Only channels using exec_command or invoke_shell without a pty will ever have data on the stderr stream.

The timeout argument can be a nonnegative float expressing seconds, or None. If a float is given, subsequent channel read/write operations will raise a timeout exception if the timeout period value has elapsed before the operation has completed. Setting a timeout of None disables timeouts on socket operations.

I wanted to run a Linux or Unix external program. For example, I would like to call an external program called /bin/date with my python script and get the output on screen or store in a variable. How do I display such output and exit status (return code) of /bin/date program using a Python script?

It builds on top of Invoke (subprocess command execution and command-line features) and Paramiko (SSH protocol implementation), extending their APIs to complement one another and provide additional functionality. That is, do I really first have to check the exit status before waiting for recv_ready() to say the data is ready?. No. It is perfectly fine to receive data (e.g. stdout/stderr) from the remote process even though it did not yet finish.Also some sshd implementations do not even provide the exit status of the remote proc in which case you'll run into problems, see paramiko doc: exit_status_ready.
