    Desired Outcome Goal:
    After setting up a z39.50 target configuration the client search is not working but reports "ERROR: Z39.50 gate error: Connection rejected by the Z39.50 database server." How to check whether the server is available?

    The best method to check if the connection can be established is to try it with yaz_client. See below example where connection is not possible. In this case contact the database provider XXXXX:

    andrea@il-aleph20(a22_2) USM01> yaz_client
    Z> auth nnn/nnn
    Authentication set to Open (LitALNet/litnet)
    Z> open tcp:nnn.n.nnn.n:nnnn
    Sent initrequest.
    Connection rejected by v3 target. <--- Connection to database is not possible --->
