Locking ESXi 4.1 mode access confirmation no access to the vCenter Server

Hello

ESXi 4.1.  I see options in conflict with access to a crowd that had lockdown normal mode activated via a server vCenter VM on a host in the cluster.  The vCenter server that sits on one of the hosts in the cluster lockeddown then became inaccessible or unresponsive connectivity wise.  So no connectivity between vCenter VM or VM vCenter and hosts.  Is someone can confirm if you can connect to this host lockedown by DCUI with root and disable lockdown configuration to allow the vSphere client to then connect to the host with root and troubleshoot the server vCenter VM?

I read in some messages that this is only possible if the vCenter VM is in place and the communication to the host.  I also read that it is possible no matter what the State of the vCenter server once Total lockdown (disabling DCUI) is not enabled.

I have this reference of the 'The new lock in ESXi 4.1 Mode' blog http://blogs.vmware.com/vsphere/2010/09/the-new-lockdown-mode-in-esxi-41.html

"With active locking Mode, the only direct access to the host that remains open is through the DCUI. This allows to perform administrative tasks limited outside vCenter Server, such as restarting the management agents and the display of the log files. In addition, you can also disable Mode of Lockdown since the DCUI. This can be useful if vCenter Server is down or unavailable, and you want to return to a direct management of the host. Normally, without locking Mode, any user to the Administrator role can open a session in the DCUI.  However, in lock Mode, the root password is necessary; no other user can connect.

Can anyone confirm.

Any other person who may not be sure these questions, I can confirm that with root credentials, you can connect to the host directly and disable the lock mode regardless of the availability of vCenter.  Only if the Total lock mode turned on, or should I say DCUI is disabled, then you have no choice but to go through vCenter or reinstall and reconfigure the network.  VM would be always available if local or have to be reassembled and re inventoried etc.

  • PIX 501 to allow access to the ftp server

    Hello

    We have a public ip address of the pix 501 and the other, I want to access the ftp server on the internal network from the outside. I tried to configure the PDM by a static nat, which translate to the address of the FTP to the public address, but then none of the stations networks could out - how can I configure it?

    I would also like to know what ports should I open on the acl for access to the ftp server.

    Thank you, daguech

    Yes, sorry... You must use the unique host for addresses command. The access list is applied to your external interface?

    for example, the command would be:

    Access-group acl_out in interface outside

    Also, can you connect to the local ftp server behind a firewall?

    We are able to go beyond the question of the installation. We did the capture of packets on both ends and discover that the reset was issued the installer by the licensing vCenter service running on the PSC.

  • ESXi 5.5 - Direct access to the local logical unit number

    I have a 5.5 stand-alone ESXi server.

    It has 2 local SAS controllers

    Controller 1 (HP Smart Array P410): data bank single RAID 10 with two VM's local logic unit number

    Controller 2 (HP Smart Array P812): only RAID 6 LUNS nothing on it yet...

    My question is that I need one of the virtual machine to access that LUN. Is it possible to give direct access to the VM to the controller and/or the unit number logic rather than create a vmdk and massive data store?

    If it is I know Flash would not work on these data, but that really doesn't matter in this case.

  • Ripping a 4.1 host in a new 5.5 Cluster WITHOUT access 4.1 vCenter Server

    I have a client who has his 2 4.1 vSphere hosts in a cluster of vCenter 4.1 which is NOT under its control or access. vCenter server access is with a 3rd party that he is nervous on his account supported by a new provider. I'm looking for the safest method (preferable without interruption) to import these 2 hosts into a whole new vSphere 5.5 cluster with 2 new hosts and vCenter 5.5 server. He has access to individual hosts via the vSphere Client as well as its local based NAS storage where the virtual machine of the resident. The end result is vMotion and Storage vMotion, virtual machine on the new guests and new storage without interruption then remove the old hosts.

    This is possible without any downtime of the virtual machine. However, as you deploy new fresh vCenter again, you will need to reconfigure settings HA/DRS. Also, since you have no control over the old vCenter, given old vCenter performance you can't as well. If you don't care about performance data, you're good to go.

    Here's how you can make this migration:

    1. deploy the new vCenter: for your condition: vCenter device will work just fine: reference:http://www.virten.net/2013/09/vmware-vcenter-server-appliance-5-5-vcsa-limitations/

    2. create the cluster on new vCenter, set up the same.  first add your new ESXi 5.5 clustered host. Make sure that the shared on the old host ESXi storage is visible on the new host as well. If it is not possible, you can run without shared as well storage vMotion. Reference:VMware vSphere 5.1

    3. now you can add your old webhost to the new cluster, make sure that vMotion requirement are already configured:

    Documentation Centre of vSphere 5.5

    4. Add your old host to new cluster. Once you add these ESXi host in new vCenter, both will be disconnected automatically old vCenter. If your host processors are different, you must enable EVC: make sure you understand impact of the VCA, the same configuration.

    VMware KB: Enhanced vMotion compatibility (EVC) support processor

    VMware KB: EVC and CPU compatibility FAQ

    5. you can migrate your old Web host VMs to new host, once the migration is complete, you can keep your old Web host in maintenance mode and remove the same.

  • blocking direct access to the oracle server

    Dear Sir

    One of our condition of pci - dss to stop direct access to the db. One solution I know:

    TCP.validnode_checking = YES

    TCP.invited_nodes = (192.168.1.91, visionhost.solutionbeacon.com)

    But this option will allow the IP address of the node invited with sqlplus using tns names also. Have any have experience to solve the problem of ending up with pci - dss?

    In which paragraph of the PCI - DSS doc that makes you think that there is a problem? I work with version 3.0 (November 2013) and I can't find anything like that. For example, paragraph 8.7 c, "review of database access control settings and application of database to verify configuration settings that the user access directly to the or queries of databases are limited to database administrators" does not say that the DBA is not able to connect to the application server. And all the stuff of firewall in requirement 1 close the access to the network and between networks, not within the network.

    Are you sure that you have a problem? There is no interest to 'fix' something that doesn't have a reference in the doc.

  • Access to the web server that is running in VMWare Fusion (Windows 7)

    Hello:

    I have an old asp application running on the Windows IIS7 server running in VMWare Fusion on my Macbook. It works very well if access http://localhost side windows in Fusion.  How do you get it from other computers on the network? I usually not done anything with access to the network on the windows side. I tried to use the same IP Mac address is visible, which is 192.168.0.xxx, that does not work. On the Windows operating system side it has the IP address 192.168.216.xxx, I think it's just a fake to connect with the Macbook side of things.

    What URL to use? VMWare Fusion additional requirements?

    Thank you!

    If you value Network Adapter to the Virtual Machine Bridged then use either DHCP or assign a proper IP address provision that is beyond the scope of the address Pool IP DHCP from the router to the network card in the Windows Virtual Machine, you can reach then the virtual machine just like any other physical local network Machine by using its IP address example: http://192.168.0.10

    If you cannot use Bridged so you use NAT with Port Forwarding.  To enable Port Forwarding on VMnet8, change you the [incomingtcp] section in Library/Preferences/VMware Fusion/vmnet8/nat.conf by the example shown in the config file.  Do it with the stop the Virtual Machine, not suspended, and VMware Fusion closed.

    I can't seem to find how to block (or redirect away from) the Web Server home page.
    For example:

    You can change the index.htm file in the htdocs OHS_HOME to do a redirection of metatag like this:



    Or you could put a rule in the httpd.conf file.

  • VM Fusion 4 - access to the Web server

    Is it possible to put in place the VM Fusion 4 with a server/service on a Windows XP image (or 7) web.

    I saw suggestions on how I can access web server/service of the Mac, but not from the wider network.

    Thanks in advance.

    Do you have properly configured the host firewall and firewalls or for test purposes temporarily disabled all firewall?

    I do not see the status of the firewall host, but by default it is and would block incoming requests.

    Firewall host is defined as follows:

    Firewall:

    Firewall settings:

    Mode: Restrict incoming connections for specific services and applications
    Applications:
    QLEnableXRayFolders: allow all connections
    com.getdropbox.Dropbox: allow all connections
    com Skype.Skype: allow all connections
    The firewall logging: Yes
    Stealth mode: No.

    That would certainly block communications in this scenario.

    Maybe you're ssl certs are not certified. You can purchase one from a certification authority or be your own and use openssl and many other methods.

    You see that the internet wants to be safe, so they want to make sure that someone will never fake like your domain name. This means CERT must be used to show another device that you are who you claim to be.

  • ESXi 5.1 status host HA is showing that the election

    Hello

    I have a node 4 ESXi 5.1 HA and DRS Cluster. Recently, I replaced all these hosts SSL certificates and prior to this activity, I had turned off the AP. Now, after replacing the hosts SSL certificates - when I am allowing the PA on the cluster, 1 single ESXi host is projection status of HA - ' Running (Master) and rest all three hosts are 'Election' HA status.»

    Tried to re - install the HA agent on the host, but issue still persists. Also tried the re - configure the AP on hosts ESXi, deactivation and activation of AP on the cluster, but no luck.

    Can someone help me for that to be resolved.

    Thank you

    KC

    Hi all

    Thanks for all your response.

    Problem is solved without the help of the HostReconnect.pl script. I followed the steps below and now all ESXi hosts demonstrate normal HA status.

    (1) put the host in Maintenance Mode. Unplug and remove from the vCenter server.

    (2) restart the management through DCUI Agent.

    (3) uninstalled the HA agent using the command line.

    (4) add the host to the Cluster.

    5) out of Maintenance Mode.

    By following these steps - correctly configured the AP on all four ESXi hosts. Now a single host is show as master and rest three hosts are displayed as slaves HA status.

    Kind regards
