I would like to mount a CIFS share on a VPN connected computer on a second remote computer mount point. Both of these run in Debian 10. The first is a local server that hosts the storage volume and the second is an AWS EC2 instance.
My attempt at this doesn't work.
sudo mount -t cifs //myserver.mydomain/myshare /mnt/myshare/ -o user=myself,domain=myworkgroup,pass=**********
I get the error
Mount error (115): Operation now in progress.
I'm wondering if there are some ports I need to open in the tunnel?
