My linux version is CENTOS, I installed the urbackup on Centos 6.8, Maybe the commands are different?
I found a similar command " start_urbackup_server reset_pw" but I think that command reset the user “admin” in the urbackup service and not the user “admin” on the web page access : x.x.x.:55414. Becuase I remember that the web access by default is without password, I set the password later.
Could it be a different setting users place store for each service (web and urbackup) ??
thanks
