Limit connections to the MTA

Hello
Due to some audit and DR concerns, we need to restrict which IP addresses are able to connect to our MTA. Currently, we have no restrictions and allow any connection. What would be the best way to limit connections?

Thank you

Doug

PORT_ACCESS mapping table would be an easy way. There are some examples in the Administrator's Guide:

  • Is it possible to limit the number of connections to the remote panel to a vi?

    Hello

    I have an application that runs on a PXI RT system and I use the remote control to access. My license allows me to have several remote connections and it's ok that I sometimes need to open several remote panels at the same time.  However, I would like to limit the number of connections for a particular VI 1.  Is this something that can be done?

    Kind regards

    Patrick Lessnick

    The way it can be done is to interview customers who are connected to the VI through a remote façade.  When you do that, you close the connection to anyone, but the first person who connected to the façade.  In this way, if someone is running the VI, no one else can connect.  Once they are made, someone else can then connect to the remote façade.  I created an example illistrates community this behavior.  You can find it here:

  • How can I connect a digital a test multiple numerical limit limit index in the database

    I am trying to store the results of our trials in the database.

    Its simple to step to a given market Index connect using the following expression

    Logging.StepResult.TS.Index

     

    However, our tests have many steps multiple numerical limit, and I must be able journal index of each test of numerical limit of the multiple steps in order to correctly return their numerical limit. The only phrase I can find that gives me this information is

    Logging.PropertyResultDetails.Order

    But the order does not quite appear to match like 1, 2, 3... but instead comes out as 9, 16, 23,... for a test and 9, 17, 25, 33, 41, 49... for another test.

    Could someone explain what is really Logging.PropertyResultDetails.Order . And if there is another term I should use to get the Index of the numerical limit for a trial of multiple numerical limit?

    Also is it a sort of reference manual that shows what kind of properties I have access to in Logging.PropertyResult I can't find that anywhere! Any help would be greatly appreciated!

    Question: I have an APEX system and I noticed some of my end users using SQL * Plus to access the data. Because I coded in the application of the special rules, I have to limit my end users and block access to Oracle, except through my application. How can I use a logion trigger to restrict access to the end users of tools such as SQL * Plus, ODBC, Crystal Reports and so on?

    Answer: It is always advisable to do what you can so that your end-users "the rules of the game" and only have access to their data to Oracle. This is especially true when you are using standard security of 'grant', but it is not necessary when using 'grant execute' security, as the end users get the data when they run your stored procedure or function.

    See my note here on General blocking access to Oracle tools.

    Block for end-users to use external tools such as ODBC or SQL * Plus, you can deploy a logon trigger to not use your application tool.
    Author of the Oracle Kamran Agayev Agamehdi has this excerpt on the prevention of external connections to Oracle

    CONNECT / AS SYSDBA;

    CREATE OR REPLACE TRIGGER block_tools_from_prod
    AFTER LOGON ON DATABASE
    DECLARE
    v_prog sys.v_$session.program%TYPE;
    BEGIN
    Program SELECT INTO v_prog
    OF sys.v_$ session
    WHERE audsid = USERENV ('SESSIONID')
    AND audsid! = 0 - check SYS connections
    AND ROWNUM = 1; -Parallel process will have the same AUDSID

    If UPPER (v_prog) LIKE '% % TOAD' OR UPPER (v_prog) LIKE '% T.O.A.D%' OR - Toad
    Upper (v_prog) '% SQLNAV %' OR - SQL Navigator
    Upper (v_prog) '% PLSQLDEV %' OR - PLSQL Developer
    Upper (v_prog) '% BUSOBJ %' OR - Business Objects
    Upper (v_prog) LIKE '% % EXCEL' - MS-Excel plugin
    THEN
    RAISE_APPLICATION_ERROR (-20000, "Development tools are not allowed here.");
    END IF;

    This is what I see on the link. but do not know if it ll work.

  • Is there a way we can configure the oracle database to accept connections from particular type. For example, we may limit Server Oracle don't not to accept applications for connection to the JDBC thin driver?

    I have an oracle server which is our recovery server disaster. When I switch my application of the primary site to secondary site, we have a window of downtime during which it must implement the secondary site. When setting up the application on the secondary site, I am getting below error please take note that primary and secondary are always synchronized. The application uses the thin driver JDBC to connect to the database.

    java.sql.SQLException: ORA-01017: invalid username/password; logon denied


    However when I use the same user name and password to connect to the SQLPLUS it connects successfully. When I use the sqldeveloper or any other jdbc connection, it fails with the above error.


    Can someone please advice what may be the setting on the oracle server that limits connections jdbc or any setting related to jdbc on the oracle client

  • limit connection based on the time interval

    Hello world.
    I would like to know, how do I restrict a user to connect to the database on specific times? For example, I want the user db to be able to connect after 23:00, of 08:AM. Is this possible?

    Hello

    Not sure if there is a medium setting to do this now, but if not, a logon trigger should do (you can select the users, it applies to).

    Something like:

    create or replace trigger deny_login
  after logon on database
BEGIN
  IF sys_context('USERENV', 'SESSION_USER') = 'NO_PRIVS' THEN
    IF to_char(SYSDATE, 'hh24') BETWEEN 08 AND 22 THEN

    It is possible that your security (firewall, antivirus) software blocks or limit Firefox or the process of plugin-container without you inform, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and allow your firewall to ask permission to get access full and unrestricted, again to install for Firefox and the plugin-container and the update process.

    See:

    Make a check of malware with several malware scanning of programs on the Windows computer.
    Please scan with all programs, because each program detects a different malicious program.
    All of these programs have free versions.

    Make sure that you update each program to get the latest version of their databases before scanning.

    Alternatively, you can write a check for an infection rootkit TDSSKiller.

    • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
    • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

    Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

    Hi AussieEgypt,

    Thank you for using communities Support from Apple.

    If a problem does not occur when it is started in safe mode, then you have already determined that the problem was isolated to a few 3rd party software running on your Mac.  Take a look at the information below to start with the removal of some elements of start-up and connection and see if the problem persists:

    Test your login items

    1. Choose the Apple menu > System Preferences, and then click users and groups.

    2. Click on your account under the current user name, and then click connection points.

      Make a list of the login items, you will need to remember later.

    3. Select all the elements of connection, and then click the button Delete .

    4. Choose the Apple menu > restart.

    5. If this solves the problem, reopen the preferences users and groups, add the elements of connection one at a time and restart your Mac after the addition of each of them.

      If the problem persists, follow the steps above to remove only the last element of connection that you added.

  • Satellite Pro M70-132: excellent WiFi connection but the pings are slow

    Hi all...
    My Satellite Pro M70-132 have problems with Wi - Fi connections (WiFi built in)... Generally, when the connection is excellent (indicator of windows), the pings are slow - very long time: 1212ms, 325ms, 645ms, 2112ms, 91ms, s 168ms... etc 'demand time limit has expired' (or sth like this).
    I have updated with the latest version of the Intel WiFi driver - it does not work...
    I installed new system - it does not work...

    Is it possible, that LAN WiFi is dead on my M70-132? How can I check before sending my 'Toshi' to the service?

    (BTW - built-in Bluetooth has been switched off...)

    I was tempted to access with several AP and also ad hoc. Every time, same results... connection strong-great but pings are slow... and often ping timeout...

    The IP address has been set manually and automatically - it does not work... too multidimensional :-(

    It's not metter WEP encryption is enabled, 'on' or 'off' and no authentication method does not change the situation with WLAN...

    Hello

    If the work of WLan connection and you are connected to the router so I guess everything's ok.
    Time to ping depends on not always the strength of the signal.

    If you ping other ip on the net if the time depends on the provider and type of connection.
    But if you ping your WLan router and it s very slow so it s a bit strange.

    If you think there could be something wrong with the Wlan card then you can try asking for help ASP.
