I worked! *But* the main problem was the connection between the TC and
the monitor: the connection was a DVI one and in spite of all change I
made to eth1, ltspbr0, dhcpd.... the TC did not boot in "ldm mode" (and
still this message in the logs:

START: ldminfod pid=22507 from=::ffff:172.31.100.100
EXIT: ldminfod status=0 pid=22507 duration=0(sec)

I changed the connection: from digital to analogic and... I got the
login screen of K12 Linux. Moreover I could log in!

Thanks for your help. I now trying to have the TC and the other
computers on the same dhcpd server; according to:
https://fedorahosted.org/k12linux/wiki/AdvancedNetworkSetup

It is not straightforward.

Best regards.
