Syntax for registering user is:

Now what i need is i want to make these users as friends by using ejabberdctl ..!!

What i tried :

ejabberdctl add_rosteritem kandan 0.0.0.001 rani

Note: I am using mysql as default database.

Could someone help me out and let me know the syntax for addrosteritem please..!!! Thanks in advance..!!!

Solution

Syntax to add roster item:

Command Name: add_rosteritem

  Arguments: localuser::binary
             localserver::binary
             user::binary
             server::binary
             nick::binary
             group::binary
             subs::binary

Hence, the command should be

ejabberdctl add_rosteritem kandan hostname rani hostname none none both
