I'm trying to set up  SIP2 so we can purchase e-books from Palace Marketplace.  So far they have not been able to connect. At first we were getting an XML error.  There's a very long <login ... in the default SIPconfiguration.xml file which was deleted but not the following </login> I know they were getting in to  our server because I could see the errors in the sip logs. When I deleted the </login> line, I updated a firewall rule in my firewall, IPFire, to log all incoming requests from their IP and port 6001.  Now they aren't getting in.  I just turned off the log request.  The rule basically says that a TCP message from their IP and port 6001 should go to our server with that port. When I first tried the sip_cli_emulator, it complained about not finding the C4 libs so I ran: perl -I /usr/share/koha/lib /usr/local/sbin/sip_cli_emulator.pl -a localhost -p 6001 -su <AdminID>-sp <AdminPassword> -l SLA --patron<myID> --password <my password>  -m patron_information and got: Attempting socket connection to localhost:6001...connected! Use of uninitialized value $hold_mode in string eq at /usr/local/sbin/sip_cli_emulator.pl line 120. SEND: 9300CN<AdminID>|CO<AdminPassword>|CPSLA| READ: 940 Login Failed! I know that both <AdminID>/<AdminPassword> and <myID>/<my password> are correct since I logged in to Koha with each of them. The sip.log is attached. I do wish that the sip_cli_emulator was in /usr/sbin with all the other koha... commands and properly setup so that it could find the C4 libs. Any suggestions? -- Bob
