    On-campus staff cannot connect to /V however they can connect to /M

    • Article Type: General
    • Product: MetaLib
    • Product Version: 4

    Description:
    On-campus staff cannot connect to /V however they can connect to /M.
    Staff can connect to both URLs (/M and /V) remotely.
    All ports are open except port 25.
    Our library's IP range is: 123.123.123.000 to 123.123.123.255
    This doesn't appear to be a firewall problem if you do the request manually using telnet:
    telnet <IP address> <port number>
    Then type either "GET /M" or "GET /V" followed by the enter key; the /V returns a blank page.
    Here is the output from when our systems person did the telnet test:
    48-186:~ mrmorlino$ telnet www.library.com 8331 Trying 123.123.123.123...
    Connected to www.library.com.
    Escape character is '^]'.
    GET /M
    HTTP/1.1 200 OK
    Date: Tue, 26 Aug 2008 20:31:03 GMT
    Server: ALEPH/5.20
    Content-type: text/html
    Pragma: no-cache
    Cache-Control: no-cache, no-store, must-revalidate

    Content-Length: 3625

    Our firewall admin enabled firewall based IP debugging on the server and confirmed that we are accepting connections from this IP; the last connection was Today
    This would rule out any firewall issue
    We tested both interfaces from multiple sources (internal/external) and verified successful connectivity using both IE and Firefox.

    Resolution:
    The cause of this behavior was due to missing information in column 4 (institution code) of the ./vir00/tab/default_z312 table.
    The only IP line containing an institution code is the 'catch all' IP; this explains why everyone in the world can see the /V except the people on campus.

    WRONG:
    >> cat default_z312
    !ip-from ip-to default user id default us
    !!!!!!!!!!!! !!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    111222333002 111222333003 LIBRARY-ENG-IN
    111222333000 111222333255 LIBRARY-ENG-IN
    000000000000 999999999999 LIBRARY-ENG-GUEST
    LIBRARY LIBRARY-ENG-GUEST LIBRARY
    METALIB METALIB-ENG-GUEST METALIB

    CORRECT:
    >> cat default_z312
    !ip-from ip-to default user id default us
    !!!!!!!!!!!! !!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    111222333002 111222333003 LIBRARY-ENG-IN LIBRARY
    111222333000 111222333255 LIBRARY-ENG-IN LIBRARY
    000000000000 999999999999 LIBRARY-ENG-GUEST LIBRARY
    LIBRARY LIBRARY-ENG-GUEST LIBRARY
    METALIB METALIB-ENG-GUEST METALIB

    Please note: There can be only 1 "catch-all" line in this file, that is:
    000000000000 999999999999 LIBRARY-ENG-GUEST LIBRARY
