Signature custom for the maximum number of connections

Hi, is there a signature to check the maximum number of connection to a host attacker to open a port to the victim? or should I make a costom for this signature?

Hello

You certainly can do it on the IP addresses, follow these steps in making a signature Atomic-ip looking for a tcp packet with only the SYN flag set on port 443 to the destination. You would then add a number of events for the number of connections you need. According to the site however this will flood the channel alarm with alerts, because traffic going out etc it will trigger. Of course, this can also be problematic with NAT.

I don't know one of the guys ASA on these forums could give an answer better than me with regard to the configuration of the SAA.

I understand they'RE a dynamic IP filtering or something that can be used to do this, although I've never configured myself.

Thank you

Neil

  • How can we formulize a threshold value for the maximum number of connections for LDAP?

    Hi all

    We use Sun one DS 5.2 on the Solaris platform.

    How can we define the value for the attribute config "nsslapd-maxconnections" because it depends on allocaated for each process's file descriptors.
    If you please also correcct me if the above statement is false.

    Thank you.

    Hello

    This attribute can be used to limit the number of simultaneous client connections slapd can handle. The main goal is to Cap slapd memory usage.
    By default, this limit is undefined, so slapd can handle up to the number max allowed for the slapd process file descriptor.

    Use only when necessary. You can use the ulimit command to get the limit of the OS settings.

  • Facing the question with the Maximum number of connections Timesten

    Hello

    In my project, I need to increase the maximum number of connections that timesten offers me. So, I changed the setting of the nucleus as shown below in the file/etc/sysctl.conf.

    kernel.SEM = 655 670720 128 1024

    The intention here is to get 500 connections max. But even after this setting too, I get only 477 connections. I don't understand why this is happening. Someone help me understand what is happening here.

    In above configuration, my hypothesis is that 155 semaphores are reserved for internal use of timesten and remaining 500 will be available for me, but this isn't the case. Please, help me in this aspect to understand why I get only 477 connections instead of 500 connections.

    Quick help is very appreciated

    Thank you

    Hi Agnes,.

    Thanks for the release of ttStatus. He explains what is happening and confirms my suspicions (second).

    The setting of the 'Connections' in the DSN attribute defines the limit superior on user connections; that is, connections by applications and tools such as ttIsql, ttMigrate etc etc. There is also the concept of connections 'system' (subdaemon, replication agent, agent of cache etc) that do not count against the total "Connections."

    In your case, the database is in fact properly configured for a maximum of 500 user connections. However, as you can see on the first ttStatus, you already have 23 application direct mode of 4 different connections methods of Java (which leaves the available user 477 connections). I of course have no idea what these applications are but probably your. This means that you are able to open additional connections a 477 application before arriving to the configured limit of 500. And that's exactly what we see; When you run your test application (what happens to connect via client/server), it reached 477 connections and then impossible to create more. As expected.

    Therefore, to allow connections you must:

    1. stop the database (replace ramPoilicy by manual (or inUse), stop all applications, stop the replication agent, unload from memory if the policy is manual)

    2. change the value for connections in the attributes of the DSN to a higher value (perhaps 600) - also, you need to make sure that OS semaphores are high enough to allow this number of connections.

    3. load the database back in memory, start the replication agent, starting applications.

    A a tied note, use of ramPolicy 'always' is not encouraged. In addition to the scenarios 'manual' is a better choice. We can "always" deprecated in a future release.

  • Hi, how to set the maximum number of connections of FMS on the same IP address

    How to set the maximum number of connections of FMS on the same IP address?

    The application.clients object available in action script server-side maintains a list of all clients connected to the Court at this moment here.

    You can browse the table and compare the property Client.ip to determine the max connections from an ip address and therefore accept/reject connections.

    It can be as simple as this in the application.onConnect

    application.onConnect = function (clientObj)

    {

    var totalConnections = 0;

    for (i = 0; i< application.clients.length;="">

    {

    If (application.clients [i] [ip] is clientObj [ip])

    {

    totalConnections ++;

    }

    }

    If (totalConnections > 10)

    this.rejectConnection (clientObj);

    on the other

    this.acceptConnection (clientObj);

    }

    Above the piece of code is untested so you may have to make some changes to make it work, but your solution should look something like this.

  • Connect the question: "you can't access this meeting because you are already attending the maximum number.

    Hello

    Since Monday, we often get the error message "you cannot access this meeting because you are already the maximum number of authorized meetings (2). "Please close one of your meeting rooms, open" when you try to enter in the meeting rooms.

    We checked several times and we * never * have other meeting rooms to open, not even to other accounts.

    We also does not change our subscription or our account.

    We then logout / login several times before we can enter the meeting room.

    It is very annoying, because we use Adobe Connect to give training courses, and teachers can not connect.

    We thought is a temporary problem with Acrobat Connect Pro, but as said, he dwells on since Monday, March 18, 2013.

    Can someone help out us here?

    Thank you

    A device can create only three accounts iCloud, after which still attempts to bring the message you see. This is related to the material and there is no way around it - reset makes no difference. What you can do is to create a new account iCloud on another Mac or iOS (not Windows) device, then you can sign in on your phone.

  • Increase the maximum number of query results

    Hello

    I need to increase the maximum search results, when I'm looking for data with data-> ValueMaxCount

    I'd like to 2000

    I tried tho change it with the help of the property page and the example given.

    The result looks like this:

    Define DataFinder = Navigator.ConnectDataFinder (Navigator.Display.CurrDataFinder.Name)
    Set IndexedFileProperties = DataFinder.GetIndexedProperties (eSearchFile)
    Set IndexedProperty = IndexedFileProperties ("fileName")
    Define ValueList = IndexedProperty.GetValueList
    DataFinder.ValueMaxCount = 2000
    Define ValueList = IndexedProperty.GetValueList

    But the quantity of serach result remains at 200

    I am referring to the wrong object or do I need to increase it to a certain point?

    Hi Janick,

    your script increases the number of values that are returned if you ask for all values that are indexed to a specific property (in the BROWSER QueryForm you will receive this list by clicking the... button to the right of the line a condition).

    To increase the maximum number of search results, you would use the MaxCount property for the elements of results.

    DataFinder.Results.MaxCount = 2000' in the search without the GUI

    or

    Navigator.Display.CurrDataFinder.ResultsList.Elements.MaxCount ' in the search with the BROWSER GUI

    What version of DIAdem do you use? 2015 tiara, it is also possible to determine the maximum number of search results in the search method:

    DataFinder.SearchElements (Query, 2000)

    I hope this helps.
