use of bptestbpcd command

Hello All,

i just want to know the use of bptestbpcd command... according to me its client connect back option..

if connectivity from client to Master/media is fine then only this command gave positive output wen i run on master/media.

For eg.

i ran this command from media server then it executed perfectly widout any error but there is no connectivity from client to media server. ping and telnet to bpcd is not working from client to media server.

then how bptestbpcd worked ftom media server to client..
