[Koha] Creating a Z39.50 Target - No connection

Hi all,

Robin, thank you for the clarification about iptables.

After setting the port back to 9999 in koha-conf.xml under root (which in hindsight, I was not doing :( ), and restarting Zebra, I've been able to telnet to that port successfully using <telnet localhost 9999> , it shows as being connected.

Yaz-client also shows the following,

        Sent initrequest.
        Connection accepted by v3 target.
        ID     : 81
        Name   : Zebra Information Server/GFS/YAZ
        Version: 4.2.18 cc3abee6f861d0166bef5333b1fc72fbdc8bd94c
        Options: search present delSet triggerResourceCtrl scan sort extendedServices namedResultSets
        Elapsed: 0.001692

Also, when navigating to library.craigbutosi.ca:9999, it displays the following, which was not there prior to doing the above:

        This XML file does not appear to have any style information associated with it. The document tree is shown below.

Looks like I'm closer to being up and running.

Many thanks everyone!

Your syntax is wrong:

telnet localhost 210

Ignore iptables, you're likely to make things worse. If the process isn't listening, no amount of messing with firewall rules is going to make it show up. iptables --list will show you what rules actually exist.

Also, iptables doesn't tell you about things that are listening anyway.
For that you want:

sudo netstat -lp --inet

> 21:04:47-07/04 [fatal] Failed to bind to tcp:@:210 [Permission denied]

This is your key thing that you need to be noticing. You don't have permissions to bind on that port, you need root to bind to ports <1024, so try for a different number and see if that works.
