How to open a port on VCSA 6.0?

I try to open a specific TCP port on the firewall on vCenter Server Appliance 6.0. I found the documentation here , but it doesn't seem to allow me to specify a port. When I telnet to my VCSA from the IP address, the port times out.

root @ < Server >: ~ # telnet < vcsa > < tcp port >

Try < vcsa >...

Telnet: connect to address < vcsa >: operation timed out

Telnet: unable to connect to the remote host

The thing turns out to be the command IPTABLES

  • Firewall: How to open a port tcp inside and out on a single line

    How can we combine the firewall command to open port 80 to tcp in and tcp out without having to publish twice?

    esxcfg-firewall - o 80, tcp, in, web

    esxcfg-firewall - o 80, tcp, out, web

    N ° because it is a completely different situation.

    When you open in port - allow you to access port 80 on the local computer from the network. When you open port - allow you to access port 80 on remote computers from the local computer. Usually there is no need to open the ports both in.

  • How to open a port that is closed? Have Vista Home premium 64-bit

    I get this message when you try to get to oracle - OEM
    "Ip_address here" is not set up to establish a connection on port "5500" with this computer. The ip address is the address of the local host - all on a single pc.

    It was woprking then I changed my security/antivirus software and the port is closed.  I uninstalled the new software and the port is always closed.

    Hi Ames66,

    It happens more often because the firewall blocks the program and to allow that program to communicate through the firewall, you can usually do that by selecting the program on the Exceptions tab in Windows Firewall.

    If you have Windows Firewall on your computer, follow the steps in this link:

    Allow a program to communicate through Windows Firewall

    http://Windows.Microsoft.com/en-us/Windows-Vista/allow-a-program-to-communicate-through-Windows-Firewall

    Open a port in Windows Firewall

    http://Windows.Microsoft.com/en-us/Windows-Vista/open-a-port-in-Windows-Firewall

    If you use a third party firewall manually give exception to the program.

    Hope the helps of information. Please post back and we do know.

  • How to open the port 161 on the ASA and Cisco switches for monitoring of BB

    Dear all,

    I want to install BB to monitor snmptraps suffering of failure.

    The newspaper shows BB cannot connect to all ports of the switch 161, and I even can't telnet to 161 XXX_17f for example.

    My switches are Cisco C3550, C2950, etc. of the ASA.

    Mon 7 Nov 15:43:03 2011 bbnet cannot connect to the server XXX_17f on port 161

    Mon 7 Nov 15:43:03 2011 bbnet cannot connect to the server XXX_9f on port 161

    Mon 7 Nov 15:43:03 2011 bbnet can't connect to XXX server on port 161

    Thank you

    Anson

    no need to adjust anything in bb-hosts. If you have added setings in bb-hosts, delete them. Also remove associated in bbvar/logs log files. (otherwise, you'll have purple when you delete the SNMP, trap tags bb-hosts)

    A column of trap will be that no show until the device sends a trap to BB.

  • How to open all ports through a VPN

    I'll put up a second exchange server 2010 in a place of DR and a few problems.  The two sites are connected by a pair of ASA5510 via the VPN, point-to-point.  I want to exclude any possible VPN problems which maybe blocking ports and I wanted to know if there is an easy way to do it and just allow all unrestricted traffic between the two ASAs.  I have attached the configs recurees here... Ewing is the main site and DBSi's DR site.  I would appreciate help on this one!

    Hello

    Seems to me at least that they both have "sysopt" configuration which controls the VPN traffic entering the "external" to its default interface

    And the default setting is that all traffic entering the ASA via a VPN connection will bypass the ACL attached to the "outside" interface

    The command is "vpn sysopt connection permit". By default put in is not indicated when you issue the command 'show sysopt run '. So you can't really see in your running configuration.

    Personally, if I don't get something not working after doing the settings, then I trust simply is newspapers that ASA sent to Syslog server or I followed the newspapers in real-time through ASDM.

    If that gives no idea of what is the problem, I probably set up a capture on the ASA to confirm that when I see a link that I also see the return of traffic for this connection.

    I also use the command of "packet - trace" often enough to verify that the appropriate NAT configuration is applied to the connection that a user tries.

    Format of the command would be

    entry Packet-trace

  • How would open a range of ports?

    I play a video game on my computer that requires the use of several ports to open at the same time, but can not find all the information on how to do this when you use the Windows Firewall. I can open the ports one at a time, but it would take a week to watch this range. (Not really, but you know what I mean) So, I guess my question is, "How do I open a beach using the Vista firewall"?

    Hello Vercetian,

    Thanks for posting your question on the Microsoft answers Community Forum.

    After researching, I found another question on the same issue:
    It comes from the http://www.dslreports.com/forum/r19700203-Vista-Opening-Multiple-ports-in-Windows-Firewall
    This Cable Guy article reiterates that you can apply a list of ranges of ports, IE. format CSV (values) separated by commas. Again, try to create the list in Notepad, then copy - paste of the list for Windows Firewall.

    Exceptions can be configured for all or multiple ports

    When you configure an exception based on the ports with the current Windows Firewall, you can specify a single TCP or UDP port. With the new Windows Firewall, you can also specify all ports TCP or UDP (for all TCP or all UDP traffic) or a list separated by commas of several ports. To configure the new Windows Firewall for a range of ports, you must specify all the ports in the range. For example, if you want to configure an exception for the range of ports 1090-1095, you must configure the following ports: 1090,1091,1092,1093,1094,1095.

    Hope that answers your question.
    Please reply if this solves your problem or if you need further support.

  • How open/forward ports on a workstation?

    Hello!

    I am running a VMware workstation, windows xp SP3.

    My primary operating system is Vista

    My guest OS is XP

    My network is bridged (?) to the guest OS.

    How would I go about opening a port forwarding / on the guest OS? Trying to play an online game.

    Thank you very much for reading,

    Spen.

    If your network is configured to use the Bridged mode, then nothing in the VMware software for you to do.  Check your Windows Firewall settings in your host and your guest.

  • Tecra M1 - Modem does not work (could not open a port)

    I have a problem: after you have reinstalled Windows XP and on my Tecra M1 drivers, modem does not work. It can not diagnose himself - he always comes a warning: "cannot open a port (COM). It can be used by another device or application. I installed the latest Toshiba drivers for the modem, but nothing changes. How can I solve this problem? Looking forward for your advice!
    Best regards.

    Hello

    Have you installed the drivers in the correct order? Not? So do it!
    Have you installed the software or additional devices which could have a bad influence on the modem?
    Check the status of the modem in Device Manager. You don't see any yellow exclamation?

    Try to start the test on the modem within the operating system.
    Check the operation of the Modem under
    Start-> Control Panel-> phone and Modem Options-> Modems tab-> properties-> Diagnostics
    by pressing the 'button interrogate Modem.

    If the information window about the Modem contains a list of COMMANDS (including ATI2, ATI3, ATI4 etc.), then the modem is installed correctly. The ATI5 command ends with the number for the parameters selected regional (for example Germany = 06).
    To change the regional setting please use the Toshiba Internal Modem region Select utility.
