yes , as ralph said , both my secretwords in two nodes are integer.
i changed my secret and it didn't inform last error anymore,
but sadly , it produced new error
in node hewonty i did
[hewonty at hewonty doc]$ mpd &
[1] 4293
[hewonty at hewonty doc]$ mpdtrace -l
hewonty.homelinux.org_32800 (192.168.2.2)
[hewonty at hewonty doc]$
hewonty.homelinux.org_32800(handle_rhs_challenge_response 788):
INVALID response in rhs response
msg=:{'ifhn': '192.168.2.3', 'cmd': 'challenge_response', 'port': 32774,
'response': 'X\xc5\x8f\x9ccfS\x8e\xaa\r\xde6$Y+\x81'}:
in node vm1
[hewonty at vm1 ~]$ mpd -h hewonty -p 32800
vm1_32774 (connect_lhs 635): NOT OK to enter ring; one likely cause:
mismatched secretwords
vm1_32774 (enter_ring 566): lhs connect failed
vm1_32774 (run 233): failed to enter ring
ah for testing , my secret for hewonty is asdfghjkl1 , for vm1 is
qwertyuiop1
Thanks,
Tiep.
