Hi Carlos,

Thanks for help. I modified tm_clone.sh and it is working fine now.
I am enclosing below the part of the script which was modified (from 43th
line).

Regards,
Łukasz



if [ `ssh $DST_HOST 'ls '$DST_PATH' '` ]; then
  log "Disk image predeployed"
else

  log "Creating directory $DST_DIR"
  exec_and_log "ssh $DST_HOST mkdir -p $DST_DIR"


  case $SRC in
  http://*)
      log "Downloading $SRC"
      exec_and_log "ssh $DST_HOST wget -O $DST_PATH $SRC"
      ;;

  *)
      log "Cloning $SRC"
      exec_and_log "scp $SRC $DST"
      ;;
  esac

  exec_and_log "ssh $DST_HOST chmod a+w $DST_PATH"

fi
