authentication trouble to remote host

[dreyna01]

Hello all,

I'm new to Stackstorm, I'm getting this error when trying to run linux.check_loadavg from the Stackstorm server to a remote host or to itself. Any advice would be greatly appreciated. Thanks in advance

st2 --version
st2 3.7.0, on Python 3.8.12

failed connecting to host q must be exactly 160, 224, or 256 bits long

and
failed: true
return_code: 127
stderr: 'bash: /tmp/62e80e250e6a518eabd95ff4/check_loadavg.py: No such file or directory'
stdout: ''

Are the other linux actions via st2 running OK on that host?

[dreyna01]

hi, thank you for the reply. None of the linux actions succeed.

actually, linux.vmstat succeeded successfully.

I got this resolved. First it was a cryptography issue with paramiko on the stackstorm server. Not sure if it was the pip3 install paramiko or the pip3 update to paramkio that fixed that one. Second, it was an sftp issue. Had to change a line in /etc/ssh/sshd_config from Subsystem sftp /usr/lib/openssh/sftp-server to Subsystem sftp /usr/libexec/openssh/sftp-server. Third, i did a pip3 install st2client on the remote host I was trying to run check_loadavg against. Lastly, created a python link in /opt/stackstorm/st2/bin/ on the remote host. I forgot this but I think before all of this, I had to do a pip3 install orjson on the stackstorm server

I suppose I should mention it really helped to go through the st2actionrunner logs in /var/log/st2
