            1. Follow this guide to create and add a new SSH key.
            2. Follow this guide to switch from HTTPS to SSH.

            Paramiko authentication fails with "Agreed upon 'rsa-sha2-512' pubkey algorithm" (and "unsupported public key algorithm: rsa-sha2-512" in sshd log)
            Asked 2022-Jan-13 at 14:49

            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?

            AWX all jobs stop processing and hang indefinitely -- why
            Asked 2021-Dec-21 at 14:42
            Problem

            We've had a working Ansible AWX instance running on v5.0.0 for over a year, and suddenly all jobs stop working -- no output is rendered. They will start "running" but hang indefinitely without printing out any logging.

            The AWX instance is running in a docker compose container setup as defined here: https://github.com/ansible/awx/blob/5.0.0/INSTALL.md#docker-compose

            Observations

            Standard troubleshooting such as restarting of containers, host OS, etc. hasn't helped. No configuration changes in either environment.

            Upon debugging an actual playbook command, we observe that the command to run a playbook from the UI is like the below:

            ssh-agent sh -c ssh-add /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data && rm -f /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data && ansible-playbook -vvvvv -u ubuntu --become --ask-vault-pass -i /tmp/awx_11021_0fmwm5uz/tmppo7rcdqn -e @/tmp/awx_11021_0fmwm5uz/env/extravars playbook.yml

            That's broken down into three commands in sequence:

            1. ssh-agent sh -c ssh-add /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data
            2. rm -f /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data
            3. ansible-playbook -vvvvv -u ubuntu --become --ask-vault-pass -i /tmp/awx_11021_0fmwm5uz/tmppo7rcdqn -e @/tmp/awx_11021_0fmwm5uz/env/extravars playbook.yml

            You can see in part 3, the -vvvvv is the debugging argument -- however, the hang is happening on command #1. Which has nothing to do with ansible or AWX specifically, but it's not going to get us much debugging info.

            I tried doing an strace to see what is going on, but for reasons given below, it is pretty difficult to follow what it is actually hanging on. I can provide this output if it might help.

            Analysis

            So one natural question with command #1 -- what is 'ssh_key_data'?

            Well it's what we set up to be the Machine credential in AWX (an SSH key) -- it hasn't changed in a while and it works just fine when used in a direct SSH command. It's also apparently being set up by AWX as a file pipe:

            prw------- 1 root root 0 Dec 10 08:29 ssh_key_data

            Which starts to explain why it could be potentially hanging (if nothing is being read in from the other side of the pipe).

            Running a normal ansible-playbook from command line (and supplying the SSH key in a more normal way) works just fine, so we can still deploy, but only via CLI right now -- it's just AWX that is broken.

            Conclusions

            So the question then becomes "why now"? And "how to debug"? I have checked the health of awx_postgres, and verified that indeed the Machine credential is present in an expected format (in the main_credential table). I have also verified that can use ssh-agent on the awx_task container without the use of that pipe keyfile. So it really seems to be this piped file that is the problem -- but I haven't been able to glean from any logs where the other side of the pipe (sender) is supposed to be or why they aren't sending the data.

            Had the same issue starting this Friday in the same timeframe as you. Turned out that Crowdstrike (falcon sensor) Agent was the culprit. I'm guessing they pushed a definition update that is breaking or blocking fifo pipes. When we stopped the CS agent, AWX started working correctly again, with no issues. See if you are running a similar security product.

            OpenSSH uses different formats for private EC keys, the SEC1 (as generated by your Go code), the PKCS#8 or the newer OpenSSH format (as generated with the ssh-keygen command). This is described here, which also contains a more detailed explanation of the OpenSSH format. The SEC1 format is explained e.g. in this post.

            The current Go code generates a SEC1 key with wrong header and footer. This turned out to be the cause of the problem! To fix the bug, ECDSA must be replaced by EC in header and footer:

            Git just runs ssh to connect to a host. Once connected, Git has that ssh run an appropriate Git command on their end, to handle the fetch or push operation. But the entire authentication process—determining who you are and deciding whether you have access—is wholly up to ssh and Git plays no real part in this process.

            Your ssh -Tv is therefore the crucial debug output here. We see that your connection to github fails to authenticate as you, after trying these keys:

            Server SSH Fingerprint Failed to Verify
            Asked 2021-Oct-28 at 22:30

            I've got a local Swift Package Manager package that uses a private Github repo as a dependency. When I open the local package with Xcode, it fails to “Resolve Packages” with this error:

            Error while fetching remote repository: git@github.com:mayoff/Preamble.git

            However, if I use the command line swift program, it can clone the private repo. For example, I can run swift package show-dependencies in the local package's directory without complaint. I can also successfully clone the remote package repo with git clone. So it's not a problem with my .known_hosts file or my SSH key.

            Anyway, double-clicking the error message brought up a dialog box that let me tell Xcode to trust the Github server:

            each ssh server have host ssh keys, which are used for

            1. auth host and later check that you are connecting to the same host
            2. to establish secure connection (exchange credentials in secure way)

            So first time you are connecting to any ssh server, you will get public key and fingerprint of this key, and proposition to store fingerprint in "known hosts" file.

            fingerprint is a new option just in addition to "yes", so you can provide fingerprint manually if you have received it in other way. https://github.com/openssh/openssh-portable/commit/05b9a466700b44d49492edc2aa415fc2e8913dfe
