How do i setup a local server such that whenever someone telnets in to the server at the specified port number , a python command line must be displayed at the specified location on the remote machine so that i can remotely run my python modules.
I'm new to Python. So Please enlighten me whether this is possible. If so How?
It is more a question about how to invoke a program when someone connects to a telnet server. The program could be written in any language (including, but not restricted to python). The answer depends on the operating system of the remote server. You also have to differentiate if you want to have this behavior for all users that log in, or only to some users.
WMI might be the answer you want. And Here is a good tutorial.

I must say that I haven't coded seriously since university, latest in '92...
Since then I've just done some simple VB, so no real coding :)
I am trying to get some python coding done so that I am sending a remote command over SSH and I retrieve the output. Basically I am catting a text file and I am retrieving the contents of the file.
I have seen various methods to do this via SSH, using an ip address, port, key, etc, while opening the tunnel.
Yet, in my case, I have to manipulate the tunnel via some special server control, with web access, invoking Ajax commands, etc.
Relevant here is to just say that I have the python code to open and close the tunnels. What I need is to insert a simple snippet of code to execute a cat and to retrieve the output.
Can someone enlighten me on how that can be done? I don't need elevated access for the command, of course.
Any guidance would be much appreciated.
I am using python 3.6.4.
TIA
Is it possible to create a hyperlink/button that calls a bash/python script on the user/local machine. I did search on the topic but there is a lot of discussion about the opening a port to a server (even the local port) but I don't want to open a port but execute everything locally. Is this even possible?
Thanks
No. That is not possible. Nor desirable, due to the security implications.
I am writing a Python script that creates and runs several VMs via virsh for the user. Some of the configuration has to be done by executing commands inside the VM which I would want to do automatically.
What would be the easiest way to get remote shell access in Python? I am considering the following approaches:
To use the virsh console command as a sub-process and do I/O to it.
To bring up an SSH session to the VM. I can configure the VM before it boots by editing its file system so I know its target IP address.
Any better API for doing this. RPC?
I need to get the return values for commands so I know if they executed correctly or not. For that matter I need to be able to detect when a program I invoke has finished. Options #1 and #2 rely on scraping the output and that gets complex.
Any suggestions much appreciated.
I am writing a script in python, and part of it needs to connect to a remote computer using rdp. Is there a script or an api that I could use to create this function? Also, if there is not, is there a way to package a rdp application along side python and then use a python script to run it? Any help would be much appreciated. Thanks in advance, Nate
If you need an interactive window, use the subprocess module to start your rdesktop.exe (or whatever).
If you need to run some command automatically, you're probably better off forgetting about RDP and using ssh (with passwordless, passphraseless authentication via RSA or similar), psexec (note that some antivirus programs may dislike psexec, not because it's bad, but because it's infrequently been used by malware for bad purposes) or WinRM (this is what you use in PowerShell; it's like ssh or psexec, except it serializes objects on the sender, transmits, and deserializes back to an object on the recipient).
Given a choice among the 3, I'd choose ssh. Cygwin ssh works fine, but there are several other implementations available for Windows.

As per this GitHub comment, you can try to use libfreerdp via ctypes in Python.
See: FreeRDP library at GitHub which is a free remote desktop protocol library and clients.

I'm writing a Python script to access all computers on the network, log in to them and read some log files. I don't want to use something as low-level as socket, but I can if I must. I realize that my problem is similar to this question, but not the same.
Are there any modules for accessing external Windows machines?
Has anyone done anything like this before?
I'm specifically looking to log into Windows 7 machines, not unix.
Let's also assume that each computer I want to log into has Remote Desktop installed and enabled. I'm also not worried about network security or encryption because these files are not confidential. Windows machines don't have SSH installed on the by default do they?
There has to be something on the other side for you to talk to. This limits you to either setting up a "server" on each machine, installing a real server (i.e. sshd), building a "server" yourself and installing it, or using a built in and active feature of the OS.
Based upon this, what kind of system do you want to set up on these machines? What does it need to do? Just read the contents of a prespecified file list? Will that list change?
One solution is to turn on telnet, and use paramiko or twisted to
talk across it. This isn't very secure of course
Next up, set up a samba share, and access the folder remotely. This
is also insecure, though less so than telnet
You could find a ssh daemon port and run that, if you are so inclined
Psexec from sysinternals might work
Use twisted to build a server app with the features you need
Use ncat to listen on a port and spawn a cmd prompt
Be aware that most of the solutions for accessing windows remotely are... poor. The best solution is probably to roll your own, but that is hard work and you will probably make mistakes.
Also, Windows 7 is not exactly multi-user friendly. Individual processes can run as separate users, but the OS does not support having multiple users logged in at the same time. Someone is going to be the "user" and everyone else is just a process with a different credential set.
This is more an artificial limitation on M$'s part than anything technical. To see this in action, try to log in with RDP while a user is logged in locally. Fun times.
Per your edit, the easiest thing to do is just set up a samba share on the box.
After this share is set up:
with open(r'\\myCompNameOrIP\C\windows\logs\logfile.txt','rb') as logfile:
loglines = logfile.readlines()
Or you can use the gencat sample found here. Just give it r'\\myCompNameOrIP\C\windows\logs\*.txt' as the search path and watch the magic.
From Ubuntu I use samba:
In Bash:
gvfs-mount smb://them/folder
Here I give name, domain and password
Then in python:
folder = '/home/me/.gvfs/folder on them'
using the os module I read folders and files inside.
I am working in a small business environment.
Why not have each of the computers send the log file to the central computer?
