  I would remove the 2 lines of ACL 101 above because it is incorrect.

  Secondly, from the output of ' cry ipsec to show his ", you seem to be getting the ip address of the"jdv1.australis.net.au", not"CorpVPN"pool pool. Therefore, the No. NAT ACL on the management interface is incorrect. I would just add a greater variety of education no. NAT so that it covers all your ip pool:

  access-list no.-NAT-DU-MGMT scope ip 10.10.10.0 allow 255.255.255.0 172.18.0.0 255.255.255.0

  Thirdly, even with your dynamic ACL 'OUTSIDE_cryptomap_65535.65535' crypto map, it only covers the 172.18.0.32/28, so I just want to add a wider range since it seems you get the ip address of the different pool:

  OUTSIDE_cryptomap_65535.65535 list of allowed ip extended access all 172.18.0.0 255.255.255.0

  Then I would disable the following group of access for purposes of test first:

  no access-group MANAGEMENT - OUT Interface MANAGEMENT

  Finally, please clear all the SA on your ASA and xlate, then reconnect to your vpn client and test it again:

  delete the ipsec cry his

  clear the isa cry his

  clear xlate

  Please let us know how it goes after the changes. If it still doesn't work, please please send again the last configuration and also to send the output of the following:

  See the isa scream his

• Second NETWORK card takes over the management network

  I have a lab of dev ESXI 5.5 on a Dell PowerEdge 2950 with a dual port GbE NIC (Broadcom NetXtreme II BCM5708).

  My basic configuration was a port of configured NIC (vmnic0) with a switch (vSwitch0) Standard.  vSwitch0 was a group of Virtual Machine (for VMS) ports and a VMkernel Port (for the management network).  Everything worked well at this point.

  When I try to configure the second NIC (vmnic1) to a different network switch port and different to connect to iSCSI, network range vmnic1 took over the management network even if it does not show as being the management network.  After that, I'm more able to connect or ping the IP of vmnic0.

  When you configure the vmnic1, I added connection Type of VMkernel.  I did not choose to use the port for traffic management group.

  When I look at the console and choose to configure the management network I see only being vmnic0selected network adapter.

  Am I misunderstood the management network configuration?  If not, does anyone have a suggestion on what may be wrong or how I can diagnose?

  Thank you for your comments!

  I think I knew what was going on.

  I had my VMkernel for networking (192.168.2.0/24) in a different subnet to the VMkernel for iscsi link port (192.168.1.0/24).  The problem was due to the existence of a network trace unidirectional from 192.168.1.0/24 to 192.168.2.0/24 (but not in the opposite direction). As stated in the post of the blog below and elsewhere, if there are two VMkernels in networks with a direct route, the esxi host will be simply choose one of the VMkernels to act as the management network (no matter if only one of the VMkernels has active network management).

  I thought my networks did not have a direct route because of the impossibility (192.168.2.0/24) management network to communicate with the network of liaison port iscsi (192.168.1.0/24) but because the 192.168.1.0/24 network may route to 192.168.2.0/24, he made the two viable VMKernels to act as the point of view of the host management networks.

  After that I moved the post iscsi binding to a switch with no network route, my problem has been resolved.

  Re-reading the following is a blog post that helped me to understand my problem.

• ESXi 5.5 - unable to connect to the management network

  I've been using ESXi for v3.  I have a small cluster of HP DL360 G5 where I was using ESXi 5.1 update 1.  I brought a new DL 360 G5 into the mix and decided to install 5.5.  After the installation, I'm going to set up the management network as usual and even after a reboot, I'm unable to access the site via http or the vSphere client.  For help, I installed the version of HP with CIM providers and I installed the stock VMware 5.5 with current pilot Rollup and they all exhibit the same behavior.  It starts fine, but I can't connect to the management network.  Curiously, however, they address IP does not respond to a ping.  I installed the 5.1 update 1 on the same server and it works fine.  Does anyone have an idea on what's going on?  Are there recommended troubleshooting steps?  It's strange to me because the ESXi has always been very reliable on HPs.

  Thank you - Greg

• Unable to activate the management network...

  I'm new and VMWare VSphere and I tried to connect to a server with VSphere ESXi 4 but I kept getting hung up on the screen «Download tools to manage this host From...» ». I disabled the management network, hoping it would allow me to bypass the connection and enter the server, but he clung to the option 'download... Tools '. "the screen again, but this time with a 0.0.0.0 IP. I tried to activate the network again, but now I get the error, "Management Network Interface was not found". I don't know what this means and I'm having a devil of a time to discover.

  Hello

  The screen you see (yellow screen with 'download... Tools) is the screen of the ESXi server. to manage the ESXi server and the virtual machines installed on it, you need to connect to a windows box, navigate to the IP address (using a web browser) indicated on the yellow screen and then download the VSphere client tool, of course ensure your network working properly. The VSphere client tool will then connect to the ESXi and manage accordingl.

  Hope this helps

• Is it possible to stop the conversion through the management network?

  Our management 172.16.0.0/16 network and our production network 10.0.0.0/8

  When we try to make the P2V conversion, all traffic through the firewall that we use for routing between 2 networks, that really is not set up to deal with a lot of traffic and that is what is extremely slow conversion.

  Is it possible to get the converter to push this traffic through the network of production instead?

  the system is 3 ESXi hosts grouped in vcenter 5.5.  Is the storage on a San

  ESX expose NFC (network file copy) as a service that uses a converter to perform conversions and NFC uses the management network. As far as I know, it cannot be changed.

  There is one exception, if--if you do Linux P2V, cloning goes through the network of the virtual machine and you will not have this problem.

  I think you may have a more general with this configuration problem, as the NFC is used not only by the converter (for example, SRM, VMotion, etc...). See this: why vMotion uses the management rather than the network vMotion network?-frankdenneman.nl for something completely different, but which may sometimes cause a problem with this Setup.

• implementation of the Hosts file on the server for the entire network?

  I see a lot of information on how to edit the local Hosts file on individual computers. But, is it possible to edit a Hosts file and have effect throughout the network?

  We have a network of a little over half a dozen of Mac mini, who take their DNS information from another Mac Mini running the application server OSX (under El Capitan). This server is the primary DNS machine for the network. I want to implement a Hosts file for the entire network.

  Parental control seems to be broken in OSX El Capitan, so this seems like the best next to us, short option to buy some third-party service, which I prefer not to do.

  I think that dnsmasq installation on your Mac server and configuration of all your computers to use as your "DNS Server" will achieve what you want.

• connections of RAW socket to the server inside the corporate network

  Hello!

  I have not found any documentation anywhere elsewhere I hope someone can help out me.

  o know for ftp/http there are a proxy that is used in the scope of work to access the servers inside the corporate network.

  But what is the best practice for an application installed on the perimeter of work to establish a raw socket connection to access network resources other than http/ftp behind my corporate firewall? so I want something like

  sock int = socket (AF_INET, SOCK_STREAM, 0);

  Connect (...) //using a host/ip within my company and port 1234

  Write (...)

  Close (sock)

  is this possible?

  and second: will it work if I use QTCPSocket?

  Hello.

  Yes, there is a recommended approach to do this for the current version of BES.  A HTTP proxy is used to connect to both corporate and external networks internal when in the scope of work.  To connect to a particular host and port, you HTTP CONNECT request to the proxy, and then once the connection is established, you have a connection with the remote server socket.  I wrote a sample application that covers the QTcpSocket / QSslSocket, BSD sockets, OpenSSL taken and connections of curvature (the species is supposed to be transparent, but there has been problems reported with some built OS).

  I'll clean up this sample application and submit for review before it is posted on GitHub.  If your need is urgent, I could share a few code snippets to help you to implement the solution for your specific use case.

• Problem with El Captain (5.1.7 server) and the management of permissions

  Hello world

  I have a big problem with our Mac Mini Server (El Captain) and the server program.

  In recent weeks, the server didn't give the permissions of a folder.

  for example:

  Mr. X had permission to read and write to a folder.
  Mr Y too.

  Mr. X has create a new folder one record something in it.

  Mr Y had the permission to read or write to the folder create Mr. x. But he should have.

  Or

  Mr. X has save a file to a folder

  When he opens it again it is write protected and cannot be replaced.

  So you have to save under a different name in the same folder.

  And every time he save/close the file.

  Anyone know what could be the problem?

  Thank you

  Greetings from the Germany

  Chris

  My guess:

  A few weeks ago someone messed with the permissions on your server and made a mistake. So, you got an inappropriate list ACL (Access Control), which is rampant in the file and must be removed or fixed.

• Is it possible to put a server on the DMZ SQL

  Hi all

  He would ask about the deployment of PIX. Is it possible to put a server on DMZ SQL (or one of 5 exclusion inside the interface interfaces) and simply define a NAT to allow inside the user access to the DMZ? Also without allowing the outside user access to SQL server. We intend to set a SQL on a DMZ server, such that unathourized internal users will not be able to know the actual address of the SQL Server.

  Are there problems which should be considered on this deployment?

  Thanks in advance,

  udimpas

  Hi Udimpas,

  Yes, your scenario is possible. You can put SQL Server on the DMZ network and allow access to inside users. at the same time, you can also block the access from the outside.

  Let's say, your sql IP address is 192.168.1.10 & your home LAN is 10.1.1.0/24. You can do the following:

  NAT (inside) 0 access-list sheep

  access-list allowed sheep ip 10.1.1.0 255.255.255.0 host 192.168.1.10

  by doing this, you have not nat all traffic from your inside sql server. In case you have defined everything inside your network access lists, you must open port 1433.

  list of access within permit udp 10.1.1.0 255.255.255.0 host 192.168.1.10 eq 1433

  You should not add the ACL above, if you have no restrictions from the inside, from now.

  I hope this helps... all the best...

• Installation of SQL Server for the virtual Center Server

  Hi all

  We bought 16 x 2 for ESX server CPU licenses.  So, I will prepare a database of virtual server of the Management Center 16 guests. As SQL Server 2005 Express is installed during installation of Virtual Center Server but VMware is recommended for use only for 5 guests.

  So I would like to prepare a database of SQL for VC server, please help me how to make the database to the virtual Center Server. Are there special tables, configuration, permissions. I have no experience with databases then how should I go with it. Is there a guide for it. The ESX Server installation guide explains only create ODBC connections.

  Please help me with this I would be very obliged.

  I know that the procedure is restrited 2 steps (1 and 2) on page 68, but you need to install and configure SQL Server for your business standard (I guess asking the C: or D: and data/newspapers on E :). I'm not going to explain better how to install SQL Server on a server. For the SQL Server database:

  • Step 1: you create a database storing the files on the right disk (with at least 30 GB) with a default database size to the size defined by the "Calculator" (value of + 15% on the line of your choice statistical level).

  • Step 2: On your Microsoft SQL Server, create a user of SQL Server database with the database rights of operator (DBO). The default database for the DBO User is that you defined in step 1. Make sure the database user has a role of sysadmin server or the role of database db_ownerfixed on the VirtualCenter database and the MSDB database. The role db_owner on the MSDB database is required for the installation and upgradeonly. This role can be removed after installation or upgrade process iscompleted.

  The user must be created for your standard business as service account (password never expires) with a long and complex password.

  Other steps in the document are for the ODBC connection.

  Creating the tables is made during the installation of VC. Nothing to do. A characteristic is not to stop the SQL Server agent because some tasks are scheduled in the database to 'compact' statistics.

  For the record, the database is upgraded when installing patches VC creating of new tables, updating of data type or...

• Check the configuration of my management network please?

  I'm working on the settings described in this article of yellow brick, but I don't know that I was right;

  http://www.yellow-bricks.com/2011/03/22/ESXi-management-network-resiliency/

  I have two vmnic added to vswitch0, vmnic0, and vmnic10.

  

  I have this vswitch groups of two ports, one for vmk1 vmotion and the other for management vmk0.

  Tab grouping the vmotion port group NIC I specify vmnic10 as an active adapter and vmnic0 as before with backspace set to no.

  

  On the NIC teaming tab management port network group I do the opposite, vmnic10 is in standby and vmnic0 is active, but with BACKSPACE value again.

  

  Is it OK so far?

  What I am ultimately confused by vswitch NIC teaming tab configuration is two adapters program active since they are each active for a group of different ports this vswitch? and should restore the value not in this tab as well?

  

  Thanks for any help you can provide.

  The first thing I noticed: you use the same subnet for your management and vmotion traffic.

  Use VLANs and put on separate segments (vMotion traffic is not encryted).

  Kind regards

• Vista does not recognize the printer network driver.

  Recently, I built a new desktop computer and install Vista Home Premium (64) bits.  I have a HP Deskject 5650 connected to another computer on desktop running Windows XP.  When I try to add the shared printer on the 64 bit Vista computer it will not find the drive.
  I was able to share this printer on 3 laptops 2 running HP Vista (32 bit), one XP and shared with friends running a variety of OS including Ubuntu and OS10.
  I managed to install the printer directly on the new office.  It works very well with a direct connection.
  I have found the correct driver in the prnhp001.inf of the Windows/inf directory, it contains this listed
  "hp deskjet 5600 series (HPA).

  I have attached the printer either by browsing or via its TCP/IP address.  Windows says that the xp machine doesn't have the right driver.  It askes for the directory with the correct driver.  I have it to point to the directory, but he comes back and says window cannot find an appropriate driver.  Contact your administrator for help to find and install an appropriate driver.
  Is there a way to force Vista to load the correct driver, as he did for the version 32 bit on my laptop?
  Any other suggestions would be helpful.  I would like to use Office XP as a print server for the entire network, but this problem is to thwart this attempt.

  Hi bobxnc,

  Please use the forum for Support of Vista,

  You will have to visit the HP website and download and then manually install the driver for Vista 64-bit on the Vista machine.  After installing the driver, it should connect and locate the driver on your computer to the printer.  Driver for 64-bit system are usually different 32-bit system, this could be the cause of the problem.

• the VM network migrate to different vswitch

  Hi Admins,

  My apologies if I have posted this question in a wrong forum.

  My environment includes 6 last ESXi update, vcenter server 6 last update, the web client.

  I got my Win2012 on a 6.0 ESXi VMs using the VSS vswitch0 for e/s, including the management network. (I think it's the default mechanism in VMware that if you do not set different network profiles, the VMs take the default network profile... that is to say, network of the VM on vswitch0).

  As I tried to separate the different network profiles, as, vMotion Network, Network, network management, storage network etc. VAPP, I removed the port network vswitch0 VM group. (I had to turn off the virtual machines to get this completed task). Once I removed the port network of VM group and when I created another group of port with the network name of the computer virtual by creating a new VSS vswitch2, I was unable to ping all VMs. Also, I removed it and attempted to add a new network for my machines interface virtual but could not see all network profiles associated with virtual machines.

  I have attached the screenshot of errors.

  Am I missing something here?

  Concerning

  Taz ~

  

  

  

  The virtual computer network you created on vSwitch2 isn't Virtual Machine port group, it's VMKernel port you created by mistake.

  Please remove if you do not plan to use it.

  Add the Group of ports in the Virtual Machine, and then when you change the settings of your virtual machine, under vNIC, you will definitely see this port group name.

  For the moment, I see that you have no Porgroup VM in your environment.
