I use ssh deployment on servers via ssh tunnels,
and each of its has specific options and port forwarding placed in ~/.ssh/config.
PyCharm uses by default its own ssh client when using SFTP deploy.
So, it doesn't work with these deployment servers.
How I could force PyCharm to use my default system ssh client or force to use options from ~/.ssh/config file.
Thanks.
PS: PyCharm version is 3.0.1
Provided PyCharm can be made to use port different than 22 (don't know that), you actually have two workarounds:
Simple workaround
Use port forwarding on localhost:
http://www.debian-administration.org/article/449/SSH_dynamic_port_forwarding_with_SOCKS
..and either use -F specific_config for each tunnel, or use -o to specify relevant options (that you normally have in ~/.ssh/config on ssh commandline) directly. Of course, you have to tell PyCharm to connect to localhost:forwarded_port.
Fancy/sophisticated workaround
Use dynamic port forwarding + tsocks, again described in:
http://www.debian-administration.org/article/449/SSH_dynamic_port_forwarding_with_SOCKS

Good Day
I work for an ISP and we basically manage all our switches and routers via the CLI from a Jumpbox.
I would like to automate some of my work on these devices by writing Python scripts, etc.
However, this Jumpbox (Linux), is quite old and the Python version is old. I cannot add Ansible, Netmiko, etc. Plus I'm not an Admin for that box so can't upgrade it.
My question is, if I set up my own Linux VM with all the required tools, how would I be able to access these routers and switches from my local Linux VM?
I tried setting up a Local/Remote/Dynamic SSH Tunnel to the Jumpbox, but I always end up on the Jumpbox SSH session itself.
You can use the jumpbox as a bastion host. Copy your public keys to both hosts (the jumpbox and the devices) and in your inventory file use the ansible_ssh_common_args option to set it up, like this:
[switches]
switch-01 ansible_host=192.168.0.1 ansible_ssh_common_args='-o ProxyCommand="ssh -W %h:%p -q user#ip-bastion"'
Note: you must be running Ansible version 2.
Best regards.
I have a Solaris 10 system, with Python 2.6.4, and I have to retrieve the files via the SFTP protocol, from the server, which does not allow the SSH logging in, i.e. only SFTP with RSA key is allowed. Could anyone please tell me:
is this possible at all?
is this possible with the above version of Python, or I need to upgrade it to 2.7.* work with the latest version of Twisted?
I have found this treat with the relevant information: twisted conch filetransfer
And this one: Python Twisted: twisted conch filetransfer verifyHostKey
But it is said there that Twisted first creates the SSH channel, and then establishes SFTP on top of it (forgive me for my possible misunderstanding and/or illiteracy), from the Twisted documentation:
Conch also provides an endpoint that is initialized with an already established SSH connection. This endpoint just opens a new channel on the existing connection and launches a command in that.
Will the same approach work in case you can not logging in via SSH? I.e. might it be possible to create an SSH channel if terminal SSH logging in is forbidden?
Are there any other approaches except Paramico, any other libraries that can help me in case of "No" to the above questions?
I know nothing about "Twisted". But I believe that you just have a terminology problem.
which does not allow the SSH logging in, i.e. only SFTP with RSA key is allowed
The above is nonsense. You cannot allow SFTP, but disallow SSH, because as you have already found in Twisted documentation, SFTP runs on top of SSH (this is true in general, that's nothing Twisted-specific).
What your server most probably really "does not allow" is "shell" access. That's not the same as as SSH. So the server allows SSH, allows SFTP, but does not allow shell.
Using PyCharm remote debugging is one of my favorite choices when doing deep learning jobs on Server platform. But recently I face a problem is that I have to first use SSH to login the platform then I will need another SSH to access the computing node. I may have to do this using my shell.
ssh myname#myip
ssh mynode
python myfile.py
Thus, usually when I use PyCharm. I can only do as the following:
ssh myname#myip
python myfile.py
My question is: how I can use PyCharm to double my SSH operation?
Generally, I use MobaXterm as the intermediate jump tools.
Choose Tunneling toolbar, you will get a dialog like this 1st step
Click the gear in settings box,and then edit the local port forwarding like this 2nd step
The final step, adding remote interpreter in pycharm:
3.1. Choose ssh interpreter
3.2. The host should be localhost, and port is the one mapped to your own PC. Then enter your username and follow the dialog.
Here is the figure of 3rd step
I installed a web server on a remote machine that can be only access through a ssh tunnel. Therefore, I have run with putty a ssh tunnel by specifying a port forwarding (in my case 8159). I have also configured the socks proxy on my browser to access to my remote webserver. Futhermore, with a curl command I can get the webpages if I add the following option --sock5-hostname localhost:8159.
Now, I would like to use python to request those webpages by passing through the ssh tunnel that I have configured with putty. I tried pysocks and proxy environment variables in my python code but it did not work. I would like to know if you have an idea to solve this problem.
Thank you in advance.
I am trying to write a script to use when connecting remotely to various computers in my office. We also use VNC to allow us to see the user desktops. I have been trying to find a script that would allow me to do this, but I have had no luck. Right now, we use the SSH command in Terminal (we all use Macs), which looks like the following:
ssh "hostname" -L 5901:127.0.0.1:5900
This then requires RSA fingerprint and user password. Username is never requested as it is the same as the user profile on the computer. 5901 can also be 5902, 5903, etc, depending on which display port is specified in our VNC client.
I would ultimately like to created a script that would prompt for hostname and display port, assuming username and password can be stored permanently in the script. If not, we would need prompts for those as well. Is this even possible?
I while ago had a similar use case so I put together this script:
http://code.activestate.com/recipes/576810-copy-files-over-ssh-using-paramiko/
To tunnel VNC over SSH you would need to forward port 5900 for connecting to the real xorg instance, e.g. via x11vnc, or port 5901 to connect to the first virtual xorg (e.g. via vncserver), 5902 to connect to the second xorg, etc.
I am not aware of paramiko being able to forward ports but there seems to be a pure Python module that does just that https://gist.github.com/1399529
