Description Humberto Blanco 2021-06-23 15:35:18 UTC
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

Any idea?

I try to connect from console with yaz-client but get the same error
/etc/koha/sites/catalog# yaz-client tcp:localhost:2200
Connecting...OK.
Sent initrequest.
Target closed connection

I believe that maybe need another conf in koha-conf.xml or z3950/config.xml
