kandi X-RAY | kex Summary
Kex is a python library for unsurpervised keyword extractions, supporting the following features:. Our paper got accepted by EMNLP 2021 main conference (camera-ready is here): This paper has proposed three new algorithms (LexSpec, LexRank, TFIDFRank) and conducted an extensive comparison/analysis over existing keyword extraction algorithms with the proposed methods. Our algorithms are very simple and fast to compute yet established very strong baseline across the dataset (the best MRR/Precision@5 in the average over all the datasets). The TFIDFRank is based on the SingleRank algorithm but with the TFIDF as the population term and the LexSpec and LexRank are based on the lexical specificity where we write a short introduction to lexical specificity here as it is less popular than TFIDF. To reproduce all the results in the paper, please follow these instructions.

QUESTION
I'm working with Homestead and vagrant on my local setup. My Homestead.yaml file looks like this:

I have two ubuntu aws instance and below are following details
- DevServer: 172.31.29.201
- QAServer: 172.31.30.52
I establish a passwordless SSH between two machine bu generating ssh-keygen in DevServer and copied it to QAServer using ssh-copy-id ubuntu@172.31.30.52 [ubuntu is username and 172.31.30.52 is private ip address of the QAServer)
I'm able to successfully make a SSH connection to the QAServer from DevServer without any issue
Even scp command to transfer the .war file to the QAServer tomcat8/webapps is successful. File qaapp.war is transferred to the tomcat8/webapps/ folder
...ANSWER
Answered 2022-Mar-14 at 06:24When triggered through Jenkins, default user is 'jenkins' and not ubuntu when i tried manually. So I switched the user to 'jenkins', created a new SSH file using 'ssh-keygen'. Transferred the newly created SSH file to QA server.
Now executing the scp command uses the SSH file and able to transfer the file.

I have downloaded apache karaf 4.3.3 on several Ubuntu18 machine. When I try to install feature or run any command through client, I get the below log trace. I am able to run the client when I am on the server, but it fails through the script.

Answered 2022-Jan-18 at 21:37I came across a similar problem with the script returning a "Closed" status.
After some tests, I found the script fails when there is no TTY (as is the case if you use tools like ansible)
You should use the 'batch mode' included in karaf client script, so your command would become:

I have a playbook that is launched from AWX with machine credentials, ie. with ssh_user_A. In this playbook, i need to perform a couple of tasks with another SSH user, ie. ssh_user_B.
In terms of credentials, I have:
- machine credentials for
ssh_user_Athat are OK, I can do whatever I need - a public/private keys couple for
ssh_user_B:- the public key is present on the remote host in the
~ssh_user_B/.ssh/authorized_keysfile - if I test this public/private key with a temp machine credentials (not possible in final target) and a dummy playbook or an ad-hoc module call, it works I can do whatever I need
- the public key is present on the remote host in the

...ANSWER
Answered 2022-Mar-02 at 08:54I've made a lot of tests and found the problem: by default, to connect to the target hosts, Ansible uses the smart connection plugin. In my case, the smart plugin leads to the use of the native OpenSSH.
Forcing manually the use of the paramiko connection plugin solves the problem, everything is OK (paramiko is a Python implementation of OpenSSH). Just need to add the instruction connection: paramiko at the needed level:

I have ec2 instance with ubuntu v20.04 and it has python v3.8.10 and pysftp 0.2.9.
I have generate .pem file from .ppk file using below command
puttygen sftp_server.ppk -O private-openssh -o sftp_server.pem
I am able to connect successfully to sftp server using command line-
...ANSWER
Answered 2022-Jan-28 at 09:18The error comes form underlying Paramiko and is discussed here:
Paramiko authentication fails with "Agreed upon 'rsa-sha2-512' pubkey algorithm" (and "unsupported public key algorithm: rsa-sha2-512" in sshd log)
Though pysftp does not expose the disabled_algorithms parameter.
You better switch to using Paramiko directly. The pysftp is abandoned project. See pysftp vs. Paramiko.
QUESTION
I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10):
encountered RSA key, expected OPENSSH key
Executing the same command from the system shell (using the same private key of course) works perfectly fine.
On the remote server I discovered in /var/log/secure that when SSH connection and commands are issued from the source server with Python (using Paramiko) sshd complains about unsupported public key algorithm:
userauth_pubkey: unsupported public key algorithm: rsa-sha2-512
Note that target servers with higher RHEL/CentOS like 7.x don't encounter the issue.
It seems like Paramiko picks/offers the wrong algorithm when negotiating with the remote server when on the contrary SSH shell performs the negotiation properly in the context of this "old" target server. How to get the Python program to work as expected?

...ANSWER
Answered 2022-Jan-13 at 14:49Imo, it's a bug in Paramiko. It does not handle correctly absence of server-sig-algs extension on the server side.
Try disabling rsa-sha2-* on Paramiko side altogether:

I've been using ssh keys with github for a while now. Suddenly i can't push and I'm getting a Permission denied (publickey) error.
Here's what I've tried so far:
- Checked the ssh key is in the correct directory (
~/.ssh) - Tried reuploading my public key to github (I get a message that the key already exists)
- Double checked that the output of
ssh-add -l -E sha256on my system agrees with the string in my ssh settings on my github account - Followed all the steps in the "Troubleshooting ssh" section of the github docs. (Everything seems gucci)
- Banged my head against the wall for an hour
So far nothing has helped. This is my last resort. I'll greatly appreciate any and all suggestions. Here's the output of my ssh -vT git@github.com

Answered 2021-Dec-10 at 04:25My answer might not help or sound silly. But in my situation, I'm just deleting the know_hosts file and pull/push again, then everything works as expected.
QUESTION
I've created Azure VM using Terraform:
...ANSWER
Answered 2021-Dec-09 at 12:30I tested your code in my environment and it gets deployed successfully but when performing SSH it errors out with connection timed out.
At first I modified it by using the azurerm_linux_virtual_machine instead of the azurerm_virtual_machine as Terraform Documentation mentions below , but it still failed.
The
azurerm_virtual_machineresource has been superseded by theazurerm_linux_virtual_machineandazurerm_windows_virtual_machineresources. The existingazurerm_virtual_machineresource will continue to be available throughout the 2.x releases however is in a feature-frozen state to maintain compatibility - new functionality will instead be added to theazurerm_linux_virtual_machineandazurerm_windows_virtual_machineresources.
So , as a solution , I tested again by removing the NSG rule and the NSG association with NIC using the below code , and it worked out successfully. You don't need to add the SSH Port in NSG as by default Azure checks if the OS is Windows then it will open RDP and if Linux then SSH port will be opened.

QUESTION
I am trying to use pip install git+ssh://git@bitbucket.org/my_org/my_package_repo.git to install a custom-made python package (shared by multiple applications) from BitBucket WITHOUT having to enter the SSH password.
There seems to be a lot of good information in one of the answers to this question for doing this in GitLab, etc. There's also some solid supporting information here.
I've already setup an SSH key between my local Mac and this BitBucket account. I'm able to push/pull code all the time to/from this account without having to re-enter the SSH password. Why is the pip install command requiring the password, when it's not required by git commands? Is there a way around this with BitBucket and the setup I've described?
When I run the GIT_SSH_COMMAND='ssh -vvv' pip install git+ssh://git@bitbucket.org/my_org/my_package_repo.git command recommended in the comments, I get the following (sanitized) response:
ANSWER
Answered 2021-Nov-21 at 02:34Your log does not show SSH require a password. But a passphrase (because the private key was created and then stored encrypted, protected by a passphrase).
That means any pip install should be done from a shell where eval $(ssh-agent); ssh-add ~/.ssh/id_rsa has been executed first, in order to cache said passphrase, and allow the all process to not require any input, for an unattended run.

Install kex
You can use kex like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
