ssh

• Tunnel

  Someone on the internet was actually right:

  

  Seen on stackexchange

• Remote to remote copy:

  #!/bin/bash
  
  
  SRC=$(cut -d: -f1 <<<$1)
  SRC_DIR=$(cut -d: -f2 <<<$1)
  DEST=$(cut -d: -f1 <<<$2)
  DEST_DIR=$(cut -d: -f2<<<$2)
  
  
  #echo "Sync $SRC_DIR from $SRC to $DEST at $DEST_DIR"
  
  
  if [ $3 ] || !([ $SRC_DIR ] && [ $SRC ] && [ $DEST ] && [ $DEST_DIR ]) ;then
   echo -e "Sytax is EXACTLY:\n\n\t$0 <src>:<path> <dest>:<path>\n\nEverything else fails as you did right now."; exit 2
   fi
  
  
   ssh $SRC "tar cf - $SRC_DIR" | ssh $DEST "tar xfv - -C $DEST_DIR"
  

• Use a ssh hop Best used in ~/.ssh/config:

  Host                FarEnd
  User                yakindsir
  HostName            far.away.host.com
  ProxyCommand    ssh -W%h:%p yakindsir@gateway.to.far.away.com
  

  Can be stacked

  Host                FarFarAway
  ProxyCommand    ssh -W%h:%p FarEnd
  

  Combined with the fabulous sshuttle inception is at hand:

  sshuttle -r FarFarAway 0.0.0.0/0
