The only (debug) message I got from the Director upon an unsuccessful
bconsole connection was the one produced in lib/bnet.c:566. So I
debugged it and got this backtrace:
#0 init_bsock (jcr=jcr@entry=0x0, sockfd=sockfd@entry=7,

It is strange, that bnet_thread_server() had been called with
max_clients=0. In the calling location in dird/ua_server.c:69
"director->MaxConsoleConnect" is used as a parameter.
"MaximumConsoleConnections" seems to be the according Director resource
configuration variable (bacula-dir.conf) and it was not present in my
configuration. While the documentation at
http://www.bacula.org/7.0.x-manuals/en/main/Configuring_Director.html#SECTION001520000000000000000
clearly states a default value of 20, bconsole connections suddenly
worked after explicitly setting it.
Further problems were an empty scheduled job list and manually started
backup jobs just "waiting on max Client jobs". To get Bacula basically
working on Xenial it seems, that at least the following configuration
variables of bacula-dir.conf need explicit statements:
- In the Director resource:
MaximumConsoleConnections
- In the Job resources:
Enabled
- In the Client resources:
Maximum Concurrent Jobs
