I'm trying to connect to koha through a z3950 client, when I telnet to port
2200 it works ok, but if I connect from a software like marcedit I get a
"connection lost" error and I can't recover any records

I try doing tcpdump about conection and found that only incoming but not
outgoing traffic found

#tcpdump port 2200 | grep 10.212.134.96
