Hi all, Lately the z39.50 lookup process has stopped working for the installation of Koha that I look after. (running on Debian stable) Clicking on the following: Catalog - Add biblio - Create Empty biblio, insert ISBN number, click on z3950 search button The z39.50 window pops up and only displays the following: "Z3950 Search Results, Nothing found, Still ?? requests to go" Here's my z3950-daemon-options file: # cat z3950-daemon-options RunAsUser=www-data KohaZ3950Dir=/usr/local/koha/intranet/scripts/z3950daemon KohaModuleDir=/usr/local/koha/intranet/modules LogDir=/usr/local/koha/log KohaConf=/etc/koha.conf The weird thing is that the z3950 logs in the LogDir location haven't been written to for months. There are log messages in /var/log/apache/koha/koha-error.log: 210.49.141.186 - - [07/Nov/2006:22:35:39 +1000] "GET /cgi-bin/koha/z3950/search.pl?bibid=&isbn=0198507917 HTTP/1.1" 200 1541 query=Select id,file,isbn,title,author from marc_breeding where z3950random = ? title= isbn= at /usr/local/koha/intranet/modules/C4/Breeding.pm line 167. 210.49.141.186 - - [07/Nov/2006:22:35:42 +1000] "GET /cgi-bin/koha/z3950/search.pl?bibid=&random=393126843.57083 HTTP/1.1" 200 1541 query=Select id,file,isbn,title,author from marc_breeding where z3950random = ? title= isbn= at /usr/local/koha/intranet/modules/C4/Breeding.pm line 167. 210.49.141.186 - - [07/Nov/2006:22:35:44 +1000] "GET /cgi-bin/koha/z3950/search.pl?bibid=&random=393126843.57083 HTTP/1.1" 200 1541 210.49.141.186 - - [07/Nov/2006:22:35:45 +1000] "GET /intranet-tmpl/default/en/includes/common-style.css HTTP/1.1" 200 7431 What do these log entries mean? Does anyone have any pointers about how to diagnose this z39.50 problem? Thanks, Greg
