[Bucardo-general] replication on different host

[Bozhan Bozhkov]

Hi every body!

I googled a lot, but could not find any information, how to make 
master-slave replication, when slave is different machine.
All examples are only for localhost.

I tried
bucardo_ctl --dbhost=REMOTE_HOST --dbpass=PASS add database DATABASE

but I received:
"failed: FATAL: database "bucardo" does not exist at 
/usr/bin/bucardo_ctl line 194"


So must I install bucardo on both hosts - I have read somewhere that it 
is not necessary?!

And how to describe which one is master and which is slave?

Best regards
Bozho
