If a PC with a DHCP server is connected via VPN, with her serve IP addresses on the tunnel?

Situation: we have a few portable computers test Ubuntu running DHCP servers.  We need get the updates and other changes in corporate network sometimes.  Today, we turn off the DHCP server, set up to get an IP via DHCP (besides) and make our updates.

Problem: we do not want someone accidentally connect the laptop to the corporate network, while its DHCP server is running.

Question: so, if we go via wifi using a Cisco VPN client, the DHCP server IP addresses above the tunnel?

Thanks for reading.

N ° DHCP uses layer 2 broadcasts to disseminate IP addresses.  Because your clients are connected via VPN, there is no contiguity of layer 2.  The only way he would accidentally do it is if you have configured an address to support IP dhcp as one of your VPN clients on the network, which I imagine you wouldn't.

    My husband doesn't like the itunes account is under my name.  I have a way that he can have his own name and sign on with her and still exist on the family account?  Also, have we HAVE two-step verification?   It's a real pain.

    Yes it can have its own ID and share your content via the family sharing, he needs to sign out of your ID and to create his own, then one of you needs to invite another family sharing.

  • DHCP server does not start - the storage control block address is invalid.

    I use a trial version of the Pro Workstation 12.1.1 on Windows 10. I seem to have a strange problem where the DHCP service does not start.

    I tried to go into the virtual network editor and then restore the default settings, which had no effect.

    The event viewer displays the following text:

    CreateFile Version ioctl(): VMnet8 (327680 393216): the operation completed successfully.

    / The storage control block address is invalid

    Checked the service and it runs under a local, verified system account permissions on the config dhcp / rental file in c:\programdata\vmware\ and both have system configured to full control. I tried to run the vmnetdhcp.exe in a command prompt to we hope to get additional information, but cannot be executed directly. I can't figure out how to get out of documented logging dhcp server in order to track down what could be the culprit.

    I tried to uninstall workstation, restart, reinstall, restart both unsuccessfully. I had version 9 workstation that was installed previously, in which the trial upgrade.

    Any suggestion would be appreciated.

    Figured it out.

    It appears during the workstation installation 9, he placed vmnetdhcp and vmnetnat in c:\windows\syswow64 folder. Pro 12 workstation puts these files in the default directory (C:\Program Files (x 86) \VMware\VMware workstation). The service was always pointing to the old location even SysWow64 after an uninstall and reinstall.

    I replaced the files SysWow64 folder workstation and services started right up.

    Checked the work by selecting NAT and gets an IP address from the host machine.

    Hello.

    I set up a DHCP under VMware Server 2. It is accessible by the virtual machines on the same host, but not by physical machines on the network. They can ping its IP address, but do receive any DHCP offer at the start of it. Are there additional configurations that I have to look?  The VMware networking is configured in bridged mode.

    We use Verizon as our ISP.  I was getting our email to two different companies by connecting to Verizon in with another user name and password for each company.  However, we have received messages in our email that we were almost our quota and customer emails we would not come through and have been having rebounded.  I spoke with Verizon and learned to use a 3rd party to channel messages and thus free up space from the server.  They helped me to set up the email to go in Windows Mail, but now all the email for both companies will in the same e-mail account.  How can we separate the email for both companies so that each company can log on to Windows Mail with their own separate IDs and passwords?

  • Problems with different e-mail addresses and the different Apple ID

    Hi, I have some problems with the different Apple ID and e-mail addresses connected to them, and I hope someone can help me in what to do.

    First a primer on my Apple ID

    ***@me.com - it's my account General iCloud (backup, iMessage, Facetime etc.).

    ***@losmail.no - my iTunes/App account (purchase and download music, app, etc..)

    ***@me.com: I have no problem connecting to this account (appleid.apple.com, iCloud.com etc etc..)

    ***@losmail.no: I have no problem connecting to this account in iTunes/App Store. However, I can not connect on appleid.apple.com with this account because he asked me to check the email address. However, this e-mail address use a messaging service that doesn't work anymore, so I can't check it out. Because it is a private messaging service, I want to change the Apple ID on my account @gmail.com.

    I believe, however, that the account @gmail.com has been connected to the account @losmail.no because I received my shopping etc. of my account @losmail.no sent to ***@gmail.com. These recipes also "Apple ID: * @gmail.com. When I connect to the account, however, use ***@losmail.no. However, an I said, I want to log on by using ***@gmail.com.

    What is strange is that in iTunes / App Store, I can connect with ***@gmail.com. However, this is not the same account as ***@losmail.noand previous purchases / comments etc. are not available. It's strange because said revenues (Ref. above).

    An other ting that indicates that the Apple ID where I use ***@losmail.no once was connected to ***@gmail.com, is what happens when I try to log in to ***@gmail.com to appleid.apple.com. Then, I get a message saying that the e-mail address must be verified. I can write the code sent to the ***@gmaiI.com, but it is said then that this e-mail address is already is used by another Apple ID, so it cannot be verified.

    So I guess my question is, basically, how I can change the ID of the ***@losmail.no to ***@gmail.com Apple when I can't access the account losmail, but the appleid.apple.com tells me that I need to check this email address.

    Best regards

    Hi phillla,

    Thanks for all the details with your accounts.

    Can be difficult to have more than one Apple with several e-mails all mixed together.  If an email is used with another Apple ID, for example, that e-mail can be used to create a new Apple ID or rename an old.

    The analysis of what you seem to have however...

    Your purchases are with your *@losmail.no Apple ID, but the emails for this go to your *@gmail.com email address.

    *@gmail.com is the primary e-mail address for your Apple ID *@losmail.no.

    You can connect to iTunes or manage your page ID with *@gmail.com Apple says it's an Apple ID on its own.  As an email address can only be verified for an Apple ID, which means that he must check with your *@losmail.no Apple ID and cannot be verified with *@gmail.com.

    You say you can not connect on appleid.apple.com with *@losmail.no you will need to check the email address.  You have a relief attached to this ID e-mail? This is the email that would be used to recover.   You receive your check or reset email - Apple Support

    Bottom line, you want to change your primary Apple ID but outdated to *@losmail.no to *@gmail.com, you must first rename *@gmail.com to something else and delete this email of all codes from Apple as well.  Then follow the link above to get access to *@losmail.no and control so that you can rename it.

    Best regards.

  • Help with rotation symbol and address at the top left

    I want to be able to turn a symbol on the center of my choice (or even the center of the image/symbol), but retain the upper left corner as 0,0. Is this possible? It seems that I may have only one or the other.

    My project is an image (inside a MovieClip symbol) which moves and rotates according to the direction of travel. Only problem, it's funny. And then when I Center/adjust the rotation of the image inside the symbol, its origin is no longer in the same place, and I have to give additional numbers to compensate for. I guess the reticle is (0,0) as well as the central point or rotation. I'm fine with this being (0,0), but how can I move the rotation/pivot also point? I tried to use the free transform tool to move the white dot in the Center, but little success.

    Any tips? Thank you!

    AFAIK, you must choose one or the other.  If centered rotation is important, then Center your 0,0 and use the compensation values if you need to locate the top-left corner moving ever.

    I don't know if the loading of the moiveclip in an empty movieclip can offer a solution that you want to or not.  You can rotate the movieclip centered inside and use the movieclip containing the x / values there.  It might be interesting to play with and see what happens.

  • Management network with a different IP address than the host?

    I want to isolate network traffic from my VM traffic management.  My host is on the same VLAN as the majority of my virtual machines.  Can I change the core IP network management to be different from that of my host?  Or am I stuck change IP / VLAN my hosts to something else...

    Yes, you will lose the connection to vcenter. Ideally, remove the host to vCenter, change IP and it readd back (vcenter will need access to this vlan 200 also).

  • WLC 5508 internal DHCP server issues

    Hello

    I'm hoping to get your comments around the issues of dhcp, I faced with two centrally switched Wireless LAN. I have attempted to explain the installation and the problems below and would be grateful if anyone can suggest a solution for the problems I am facing:

    The configuration is the following:

    -J' have a WLC 5508, which has been configured with 4 SSID, of which 2 are the Central authentication and commissioning.
    -J' have a LWAP connected to the WLC in HREAP mode.
    -WLC is configured as a DHCP server for clients that connect to the SSID "Guest." For the rest, I'm on external dhcp server.
    -Only one scope of comments Interface is configured on the WLC.

    Problems:

    1. as far as I know, to WLC serve internal dhcp server, it is mandatory to have the proxy enabled, but the Clients connecting to 'Internet' SSID are

    Unable to get an external dhcp server ip address, if the proxy dhcp is enabled on the WLC. If I disable the proxy, everything works fine.

    2 DHCP does not release the ip addresses assigned to clients, even after that that they are connected.

    3. If a machine that has previously been connected to "Guest" SSID connects to the 'Internet' SSID, he asks the same ip address, he was charged by the WLC assigned under "Guest", it gets the tag with the Vlan configured on the management interface.

    I put my cRIO 'DHCP' to 'local connection' and lost contact with her.

    I changed the location setting labelled '2' to post a link-local only, so I think I hit save to '3 '.  So, I have had no contact with my cRIO network.

    I tried;

    Hit the reset button

    A MAX of opening closure

    Go to safe mode

    Lift the switch to reset IP

    Power cycling the cRIO

    Directly from the host to my target of cat 5 cable running

    None of it worked, and I have no contact with my cRIO.

    This is what MAX looks like now.  How can I fix?

    It turns out that I had more of a problem.  Corrupt drivers, 255 in many in my subnet mask, overly complex LAN, use server control... you get the idea.  So I just deleted all software, disassembled everything and more from scratch.  Now back to the top and work.

    Thanks for the tips everyone, all the pieces and peace where it is useful to help me see the bigger picture.
