Note that, strangely, Hyundai lo's address 127.0.0.1 is the same as old desktop
main address. I think this generates confusion (see below).

PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.050 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.037 ms

64 bytes from 127.0.0.1: icmp_seq=4 ttl=64 time=0.039 ms
, but I suspect it confuses old desktop address: 127.0.0.1 with the same
address of Hyundai's lo. In fact, when I run rsync, it apparently transfer
files:
$ rsync -vr test 127.0.0.1:/home/rodolfo
rodo...@127.0.0.1's password:
building file list ... done
sent 97 bytes received 20 bytes 33.43 bytes/sec
total size is 24934 speedup is 213.11
but not actually, since no directory `test' is present in old desktop.
Please help.
Thanks
Rodolfo
