Ed, Here's the environment: Bulk storage server for whole home - 45drives.com Storinator - 1 of 3 payload bays populated with 15 x 4TB drives in a 39 TB ZFS raidz3 array - OS is CentOS 8.3 with array - NFS shared as /tank - /etc/exports contains /tank 192.168.1.0/24(rw/sync,root_squash) - samba not yet configured Linux laptop - ThinkKPad P72 with 2 TB NVME boot drive - OS is Fedora 33 - /etc/fstab contains store:/tank /tank nfs defaults 0 0 - tank array mounted on /tank Windows 10 Pro PC My original concept was to create a 240 GB VM in the /tank/VM/ space and prototype C7, C8, or F33 versions of a physical storage server at a client site with a 240 GB SSD boot drive and 4 x 500 GB LVM RAID5 array served out with Samba to multiple client PCs and MACs. I wanted to use a TigerVNC client on the Linux laptop to set up and configure the 240 GB VM on the storage server, but because the upstream author has munged its systemd conversion this is no longer possible. I also wanted to use RDP to connect the Windows PC to test samba connections on the VM running TigerVNC server. Unfortunately I've run into permissions hell and can get none of these working. I would like to find an alternative to TigerVNC that will work in the target environment. --Doc Savage Fairview Heights, IL
