Mounting CIFS hostfolder fails with Cipher too short

[dragos-cojocari]

General information

• Minishift version: v1.34.2+83ebaab
• OS: macOS Catalina (10.15.7)
• Hypervisor: hyperkit

Steps to reproduce

1. Create a SMB file share on the MacOs
2. Add the host folder to Minishift minishift hostfolder add share -t cifs --source //192.168.1.20/share --target /mnt/sda1/share --options username=USERNAME,password=PASSWORD
3. Mount the hostfolder minishift hostfolder mount share

Expected

The folder is mounted

Actual

$ minishift hostfolder mount share
   Mounting 'share': '//192.168.1.20/share' as '/mnt/sda1/share' ... Ciphertext too short

Note:

• the username contains a "." in it
• the password has special characters in it
• mounting the folder from a minishift ssh session works fine

minishift ssh
sudo mount -t cifs //192.168.1.20/share /var/lib/minishift/base/openshift.local.pv/pvtrain -o username=USERNAME,password=PASSWORD

Hmm, looking at the logs I realized this could be an issue with the permissions for /Users/dragos.cojocari/.minishift/machines/minishift/id_rsa which were (-rw-------). Changing the permision to that file or running with sudo results in a different error:

Password:
   Mounting 'share': '//192.168.1.20/share' as '/mnt/sda1/share' ... Unreachable
host folder is unreachable

In case it helps this is the OpenSSH version installed on my machine

$ ssh -V
OpenSSH_8.1p1, LibreSSL 2.7.3
