Hi Andy,

Thanks! It seems this is the problem.... (see below)

Both are running 4.1.1
How would one diagnose what exactly is going wrong with the routing of
the data packets here? ( I don't have root access on the manager
machine)

I focused so far only on the connection to the meta manager, but
looking more careful to the log, it seems that also the local data
server cms can not connect to the local manager although both, local
manager and data server, run on the same machine...
That's the log until the login try, don't know if there is anything
else unusual:

Changing the configuration for the data server cms from "all.manager
HOSTNAME:3121" to "localhost:3121" allows the local data server
process to login:

150109 20:08:30 5507 XrdInet: Accepted connection from 21@localhost
150109 20:08:30 5506 XrdSched: running main accept inq=0

free; 1% util
150109 20:08:30 5507 Protocol: Primary server.5526:20@localhost:1094 logged in.

So it seems you found the problem being a routing problem and probably
I should focus first to get the local data server process register
with the local manager using the hostname of the machine instead of
localhost...
But how could this be solved....?


Cheers,
  Marcus
