# 1. Generate ssh-keys on your server      #
#      cd ~/.ssh                           #
#      sh-keygen -t dsa                    #
#                                          #
# 2. Rename pubkey                         #

#                                          #
# 3. Put the file on MKT Router            #
#      ftp x.x.x.x                         #
#      ftp> bin                            #
#      ftp> put backupkey                  #
#      ftp> bye                            #
#                                          #
# 4. Import pubkey in MKT Router           #
#      telnet x.x.x.x                      #
#      [admin@mikrotik] /user ssh-keys\    #
#       import user=admin\                 #
#       public-key-file=backupkey          #
#                                          #
# 5. Access with ssh to the MKT Router     #
#                                          #
# 6. [SCRIPT] Change USER  and ID values   #
