Hi All, Can anyone tell me, how can I allow the access of Z39.50 application level access on port 210 with squid3.0 stable1 proxy server. I've some applications which talks to the application server with z39.50 application level access. Which are not working since I've changed our ms-win proxy server to Ubuntu squid proxy 3.0 stbl1. I've opned the port 210 on our proxy server with acl Safe_prots port 210 but it is not working. I'm searching on the net, but not getting enough info about this on net.Need some help in configuring this. - Sameer
