Unable to block the port with pfctl(8)

I try to block the process that is listening on the port on my MacBook Pro 9110 to simulate the network interruption.

If I have the following rule:

-------------------------------------------------------------------

block fast drop on all proto tcp from any to any port = 9110

--------------------------------------------------------------------

My second process has communicated successfully with the port is blocked, and the client has successfully sent applications to the blocked process. The best I could achieve blocks all communications process with these lists of rules:

---------------------

drop block in all

block any waiver

---------------------

However, this is exactly what I need. Am I missing something? Any commnets/suggestion will be appreciated. Here is my result of lsof command:

  • How to block the port with esxi5?

    is it possible to monitor Protocol on vps all this creat byy vmware esxi?

    like to have us add some filtering for all vps and prevent from using port 25 or...

    Just to make sure that I understand. Are you referring to virtual machines with 'vps '?

    ESXi only includes a firewall because it of own OS, but not for the VM networks. In order to monitor or block traffic, you must implement your own firewall. Depending on your configuration (single host or cluster), it can be a VM (e.g. pfSense) firewall with two uplinks, where it is connected to your network and the other on a host only vSwitch, jointly with others - being watched - VMs.

  • Unable to get the port forwarding on LRT224

    Hello

    Can anyone help with setting the port forwarding on a LRT224 - he drives me crazy!

    I have a mail server running on the internal network listening on port 443 using SSL. I want to expose it to the internet on port 450

    I tried to configure the following Port Address Translation entries:

    TCP: 450 an external Port internal Port: 443 host LAN:

    UDP: 450 an external Port internal Port: 443 host LAN:

    The two rules are enabled.

    I have not setup additional access rules, since I realized that the Port Address Translation is circumventing them.

    The setting "Block WAN request" on the firewall is disabled.

    Result - NOTHING! No link, no ports open (verified with ShieldsUp!)

    FYI - the LRT224 was purchased to replace 2 DD-WRT-flashed routers, each connected to a different ISP - 1 want to automate failover rather that physically Exchange connections of my passage to the routers.

    On the other hand, the requirement for transmission of port above took 5 minutes to the configuration via DD - WRT and worked as required from the beginning.

    I spent 2 days playing with the LRT224 and have no configuration work.

    It is a basic feature! Why is it so hard to make it work?

    All help gratefully received...

    Hi Chad,

    Just to say thank you to help get that job!

    To confirm, the resolution for anyone interested:

    The configuration of Port Address Translation was correct, but the internal server that was targeted had bad default gateway on its network card (it was targeting my other router), which meant that he was not talking to the LRT224, which means that the latter did not open the ports connected to the Internet.

  • Unable to get the max with Intel pro 3945ABG card Wlan download speed

    Grettings all,.

    I have, as the shows theme, a model of router Philips SNB650 and Intel pro 3945ABG wireless card.
    The card supports up to 54Mbps while the router can handel upp to 108mbps. The router is in the same room as my laptop and I recive full force and 45mbps connection. I also have an internet connection of 100/10 Mbps (100 downwards, up to 10). The problem is that I can never reach maxlimit when I download files.

    One I download since has the same connection as me, and through him, I get 1.45mbps, which is normal with our two connections. However, when I download it and other sources, I never reach more than 1.45mbps a total, counting all together downloads. So when I download 1.45 my brother and someone else, something with connection equalent, the download speed of my brother will decrease, as well as the other connection.

    I contacted Philips suport and asked if he could be a setting in the router which does the job in this way, but the answer I got was that I should turn on max-double-sided. I know where to find it, even if they described in their message. Network connections-> network-> properties-> advanced card and it make the change with the duplex mode. But the only option for windows, built in firewall.

    I searched on the net for possible solutions, but found nothing. However, I found a few tips about the wireless network card. And that's to go to the device run-> ECS-> NIC in question and make a few changes, such as: Power management (max game, have you tried other variants), roaming Aggressivness (set to max, have you tried other variants) and transmitting power (max by default, tried other variations).

    None of the above configurations makes no difference to my network speed. So, now I turn to you, to see if anyone has a solution. Is there a way to change the duplex mode for all wireless network cards?

    Perhaps I should mention that I have the latest drivers for my network card, but he had the same problem with the 'old'.

    Thanks in advance,
    / Martin

    Hello

    I would try to explain what I understand what you're saying.

    Even with a 100/10 connection does not mean what download you to. There are a few Web sites on the internet that test true download you have. You might want to try one, because I never downloaded to my max download rate.

    It entirely depends on many variables. The Web site you download from (they could cap their downloads to customers at 1 Mb if they chose) etc. Could be your ISP that has the problem etc.

    I doubt the computer or settings are the problem. Call your service provider and ask them what the problem is.

But, if the user has a different value as any part of the sentence "Do not to enter the e-mail address for this user' or 'identification of email without standards (id with abc@xyzcom'), we get an error during the recon.

    You can update the property with any regular expression you want. This is what is displayed in the property system.  For the issue of recon, if the e-mail address is not marked as required in your recon fields then Yes, it may be empty.

    I have another question, in the migration of the real life, our data base have a lot of CLOB datatype and logsegments, etc. What is the best practice or advice you can give me?

    I'm probably not the best guy to answer this question.

    Can I create several extracts on source and several replicat on source?

    Yes.

    Let's say we have 10 users of the application in the prod database, do at least excerpts for each schema? then within each schema, I create several snippets based on the type of data or others?

    Yes. You can create a group of extract/replicate by schema. This would help in parallelizing things.
