Depending on the nature of the proxy involved, it may not be necessary to use YAZProxy. In particular, the YAZ toolkit supports a special connection syntax to direct Z39.50 and SRU traffic through a proxy.

For example, suppose you have a Squid proxy running on localhost and listening on port 210, and further suppose that the proxy is configured to allow connecting to the target Z39.50 server(s). In that case, with yaz-client you can do something like this:

yaz-client connect:localhost:3128,tcp:lx2.loc.gov:210/LCDB

and that will get you a proxied Z39.50 connection to the Library of Congress.

It took a bit of digging but I found some information about that syntax that Galen mentioned: https://github.com/indexdata/yaz/blob/master/NEWS#L2365 So in that case you'd be doing "yaz-client connect:EDUPROXY:PROXYPORT,tcp:lx2.loc.gov:210/LCDB". Now ZOOM doesn't explicitly mention support for this syntax (https://metacpan.org/pod/distribution/Net-Z3950-ZOOM/lib/ZOOM.pod). Of course, neither does yaz-client (https://linux.die.net/man/1/yaz-client). As I said, the documentation leaves something to be desired. I'm waiting to hear back from Adam Dickmeiss about that. But looking at C4::Breeding::_create_connection... it looks like Koha would need a little patch to change how we pass in the connection string. Instead of '$obj->connect( $server->{host}, $server->{port} )', we'd want to use something like '$obj->connect($host)' where $host is constructed based on whether or not there is a proxy. (See https://metacpan.org/pod/distribution/Net-Z3950-ZOOM/lib/ZOOM.pod#new()) I could keep digging through source code but I think it'll just be easier to wait for Adam's response. -- You are receiving this mail because: You are watching all bug changes.
