Second API node is not visible on the cluster.

[Dmitry Buzolin]

Hello!
We set up two node cluster. Both nodes act as DB and API nodes, plus one runs MGM.
We use compiled sources on Fedora Core2 linux for 4.1.7 MySQL database. The MGM and db nodes and one API node start succesfully however when I start second API node it starts but "show" command doesn't list it as connected:

NDB> show
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=10 @192.168.20.101 (Version: 3.5.3, Nodegroup: 0, Master)
id=11 @192.168.20.102 (Version: 3.5.3, Nodegroup: 0)

id=6 (not connected, accepting connect from 192.168.20.102)

We don't have Ndb.cfg files instead we supply parameters from command line:
./ndbd --connect-string="nodeid=10;host=192.168.20.101:2200"
./ndbd --connect-string="nodeid=11;host=192.168.20.101:2200"

Our config.ini :
[NDBD DEFAULT]

[MYSQLD DEFAULT]
[NDB_MGMD DEFAULT]
