Hi There, Our koha version 17.11 (ubuntu 14.04) able to connect with SIP2 to one machine ONLY. FYI, we have 2 machines (Self-check, Book Drop) and a Tagging Workstation that needed to be connected concurrently. If I activated Selfcheck, Book Drop and tagging workstation will be disconnected from SIP2 . All 3 above need to be connected from port 6001 (RAW) service. How do I do that? Please assist me. Thank you. Regards Halim Our current settings is a s follows : <service port="192.168.14.15:8023/tcp" transport="telnet" protocol="SIP/2.00" timeout="60" /> <service port="192.168.14.15:6001/tcp" transport="RAW" protocol="SIP/2.00" client_timeout="600" timeout="60" /> <!--- client_timeout times out active connections which have not received input from the client. Many persistent connections will send a status request every 5-7 mins so setting this to less than that will add instability to the connection if explicitly set to zero, no timeout is applied to the connection. NB the parameter timeout applies to the login process only and should be set to a lower value to time out failed connections --> </listeners> <accounts> <login id="term1" password="1234567890" delimiter="|" error-detect="enabled" institution="Main Library" encoding="ascii" checked_in_ok="1" /> <login id="koha" password="koha" delimiter="|" error-detect="enabled" institution="kohalibrary" encoding="utf8" /> <login id="koha2" password="koha" institution="kohalibrary2" terminator="CR" /> <login id="lpl-sc" password="1234" institution="LPL" /> <login id="lpl-sc-beacock" password="xyzzy" delimiter="|" error-detect="enabled" institution="LPL" send_patron_home_library_in_af="1" av_field_template="[% accountline.description %] [% accountline.amountoutstanding | format('%.2f') %]" > <screen_msg_regex find="Greetings from Koha." replace="Welcome to your library!" /> <screen_msg_regex find="Invalid patron barcode." replace="Barcode not found, are you sure this is your library card?" /> </login> </accounts> <!-- Institution tags are for enabled branches.
