Do u mean this:
remote user , host1 with user ds1, host2 with ds2 ,ds1 and ds2 need sudo with no password
remote user , host1 with user ds1, host2 with ds2 ,ds1 and ds2 need sudo with no password
the model is standalone, seems like i dont need to configure the remote, brain broken..
remote user , host1 with user ds1, host2 with ds2 ,ds1 and ds2 need sudo with no password
thanks bro! the reason is that the server ssh 's default port had changed, i changed the ds's configuration and it works.
