For my own reference, after experimenting, the fastest transfers for copying an Epic Stores Games (lutris deployment) between hosts connected via a cat6 cable: RSYNC_CONNECT_PROG='ssh -o "Compression no" -c aes128-ctr %H' time rsync -a --delete --progress 6.6.6.11:Games/epic-games-store .

Linux: running remote X11 server with GPU access There are times where it is convenient to have a remote X11 session with access to the remote GPU.  I have used this process for many things, including running a video game remotely (for testing purposes.) Documenting this process here for me as much as anyone else who finds it useful. Assumptions root on local and remote boxes running Xubuntu (not a requirement but you'll need to modify some of these steps) latest VirtualGL is 2.6.3 and you are running 64-bit OS Setup On the remote server: Install VirtualGL cd /tmp/ && curl -sL https://sourceforge.net/projects/virtualgl/files/2.6.3/virtualgl_2.6.3_amd64.deb/download > virtualgl_2.6.3_amd64.deb sudo dpkg -i virtualgl_2.6.3_amd64.deb sudo apt-get -f install sudo apt-get install tigervnc-standalone-server sudo service lightdm stop sudo /opt/VirtualGL/bin/vglserver_config ## follow the prompts sudoedit /usr/share/lightdm/ligh
