Paramiko and exec_command - killing remote process?

陌路散爱 提交于 2019-11-27 01:54:20
问题 I'm using Paramiko to tail -f a file on a remote server. Previously, we were running this via ssh -t , but that proved flaky, and the -t caused issues with our remote scheduling system. My question is how to kill tail when the script catches a SIGINT? My script (based on Long-running ssh commands in python paramiko module (and how to end them)) #!/usr/bin/env python2 import paramiko import select client = paramiko.SSHClient() client.load_system_host_keys() client.connect('someserver',

I'm trying to do some port forwarding from a python app using Paramiko. I can set up the SSH connection just fine, but I'm a bit stumped as to how to use paramiko.Transport . I've already found this file , but I can't work out what's going on in it. From looking at the paramiko.Transport docs , it seems that a single line using the open_channel function, but I can't work out how to implement that. I'm trying to replicate a simple ssh -L 8000:localhost:8000 . Can anyone help me out? Y__ Please find some code using paramiko-1.7.7.1 , pycrypto-2.6 and the forward.py script from which I did remove

Implement an interactive shell over ssh in Python using Paramiko?

大兔子大兔子 提交于 2019-11-27 01:09:52
I want to write a program (in Python 3.x on Windows 7) that executes multiple commands on a remote shell via ssh. After looking at paramikos' exec_command() function, I realized it's not suitable for my use case (because the channel gets closed after the command is executed), as the commands depend on environment variables (set by prior commands) and can't be concatenated into one exec_command() call as they are to be executed at different times in the program. Thus, I want to execute commands in the same channel. The next option I looked into was implementing an interactive shell using

How do I change directories using Paramiko?

问题 Drush commands not executing using Paramiko I posted the above question regarding a persistent error message that I receive using Paramiko. I do not think it is related to my next question, but it might be. I can successfully connect to my server via SSH using Paramiko. I can execute commands like ls or pwd. What I can't seem to do is change directories. I can send the command "cd .." for example, but when I follow up with "pwd" it shows that I haven't changed directories. It just lists the

Read a file from server with SSH using Python

断了今生、忘了曾经 提交于 2019-11-27 00:31:24
I am trying to read a file from a server using SSH from Python. I am using Paramiko to connect. I can connect to the server and run a command like cat filename and get the data back from the server but some files I am trying to read are around 1 GB or more in size. How can I read the file on the server line by line using Python? Additional Info: What is regularly do is run a cat filename command and store the result in a variable and work off that. But since the file here is quite big, I am looking for a way to read a file line by line off the server. EDIT: I can read a bunch of data and split

Automate ssh connection and execution of program with Python's Paramiko

守給你的承諾、 提交于 2019-11-26 23:12:19
I want to automate a specific task using python. This task includes, among some other things, connecting with ssh to a remote server, and running a specific program (call it prog.out ) that may or may not ask for user input . After some research and after weighting my options, I decided to use Python's Paramiko (which may turned out to be wrong, considering the below...). Let's start with the easy possibility of prog.out not asking any input, but rather just prints some info to console: int main(int argc, char* argv[]) { printf("Hey there, fella\n"); printf("How are you this morning?\n");

Paramiko and Pseudo-tty Allocation

时间秒杀一切 提交于 2019-11-26 22:33:14
I'm trying to use Paramiko to connect to a remote host and execute a number of text file substitutions. i, o, e = client.exec_command("perl -p -i -e 's/" + initial + "/" + replaced + "/g'" + conf); Some of these commands need to be run as sudo, which results in: sudo: sorry, you must have a tty to run sudo I can force pseudo-tty allocation with the -t switch and ssh. Is it possible to do the same thing using paramiko? I think you want the invoke_shell method of the SSHClient object (I'd love to give a URL but the paramiko docs at lag.net are frame-heavy and just won't show me a specific URL
