• General question about DHCP network configuration

  In the past, I've always set up printers on network with a static IP address. With the proliferation of networked printers and progress in the printer driver software, I wonder if the static configuration is always recommended and necessary.

  Let's say I have install an Officejet 6500 wireless printer configured for DHCP and it gets an address 192.168.1.7. To continue, the printer driver is installed on the computers all networked and the printer port is listed as HPxxx192.168.1.7. After a break from running, say that the address assigned dynamically changes printer 192.168.1.5, leading to the question... to will the computers still be able to print to the printer who has now a new IP address? Basically, is the intelligent print driver so that he will direct the print jobs to the new address without additional configuration? (perhaps the answer varies depending on the printer model and the operating system of the client)

  I have installed HP network printers on a regular basis in a variety of operating system environments. So the question in more specific general. I don't feel a particular problem at this stage. But when I configure network printers in the future, an answer to the question will be useful.

  Thanks in advance.

  It depends on.  On older printers a static IP address is very important on the latest not so much. It is really dependent on the platform on which rests the HP software.  HP printers currentlyon market, in theory, do not need static IP addresses.

  In addition, when you set a static IP address, I always put one outside DHCP pool.  If the range is the range (.2 a.254) I reduced the scope and then put printers outside the pool.  This way there is never any conflict.

• Newbe question about the network configuration of ESXi 3.5

  I have ESXi 3.5 works well on a Dell Poweredge T300 server.  I want to connect a Netgear ReadyNas Pro Business Edition for this Dell and connect by iscsi.

  I want to connect 1 network card of the ReadyNas for 1 network card on the Dell printer.

  My question is on the Dell when I go to the ESXi server and customize by pressing F2 and goto network settings I see the following:

  X vmnic0 embeeded nic1

  NIC2 integrated vmnic1 used by vswitch1

  I'm may be thick but can you explain what NIC on the ESXi server is used for access interenet and I need to configure for iscsi?  I thought that it should be obvious, but it is vmnic0 or vmnic1?

  Your ESXi host has two vswitchs configured what uplinks to physical NIC in the system.

  vSwitch0 what uplinks to vmnic0 (who, although a red x, indicating a problem seems to be very well) this vswitch holds you management interface (IP 192.168.2.107) and a portgroup of VM for your virtual machines. You also have an another vswitch vswitch1 what uplinks to GB NIC vmnic1. This vswitch has unused virtual machine port group. Also a VLAN ID has been set for this vswitch which would lead me to believe that VST is / was operating on that host in the past.

  Haven't you set up this? If this isn't the case, I would get with one who did.

• I have a question about the network configuration

  Hello

  I'll set up a network with 8 computers. My logic is correct?

  I have an internet connection by cable to come in the main office. I was going to plug the BEFSR41 "Router EthernetFast cable with switch 4-port" to the internet. Then plug 3 computers and an ethernet cable that relate to an EG008W "Gigabit 8-port Workgroup switch". Then plug the remaining computers to the EG008W.

  What is the correct procedure?

• Networking question in VMware Workstation / nested ESXi network configuration problem

  Hi guys,.

  I am trying to set up a virtual lab, I setup a domain, a vcenter server and up to 1 ESXi host controller.

  I am really struggling with the network aspect in establishing a vmnic for storing shared, please see the attached screenshots and a few questions:

  1. Is a vmnic a real network map? or vmnic correspond to "network adapters" that you put in place since the setting of your virtual machine?

  I followed a tutorial and implement 3 NICs on the ESXi host, in Bridge mode, I tried this in my configuration of vmworkstation and I lose the connection to my server vcenter to the ESXi host.

  See screenshot attached to how I configured my ESXi host, screenshot is called 'screenshot2esxihost network', I run got each of the maps defined on NAT network.

  

  See also the screenshot of how I have my configuration of network settings in my VMWare Workstation, screenshot is called "screenshot1. the tutorial does not show how it has its editor of the virtual network configuration, but it puts its ESXi host NICs in BRIDGED mode, and I'm guessing that you can set this time within the virtual network adapter. If someone could tell me what changes should I make in there and on the network cards in my ESXi host, which would be really useful.

  

  My domain controller, server ESXi hosts and vcenter are currently on the 192.168.86 range, which currently stood at NAT

  See also a screenshot from the vsphere client - I don't see a vmnic "vmnic0", my goal is to be able to add a "vmnic2" for a separate storage network.

  

  any help would be received with gratitude, I VCP510 review at the end of the month and really hope to be able to get my lab setup as soon as possible.

  The vmnic is the rising 'physical' of an ESXi host. So with the 3 network cards that you configured for the host in VMware Workstation you will see under "Network adapters" and you can use them to vSwitches in the section "network".

• Network configuration required

  Hello

  in installation guide is no information on the network. I want to know how much bandwidth necessary for data collection.

  Thank you very much

  Sorina,

  I don't know any white paper on the network configuration required for data collection. I worked at Integrien before vmware bought us and nobody DON'T all talked about the record minimum network configuration. I saw him install and run without problems of collection network via a third party and vcenter data with 10,000s objects without a complaint from the network team.

  Can't say it won't happen, but I've yet to see network problems.

  You see a few questions?

• Network configuration help

  I've implemented a virtual client consisting of 2 virtual servers Server network and several virtual desktops. Server side, I have a card as full network and a 2nd card using vmnet 9. Other servers and workstations all have the vmnet adapter 9 as well. They are all together very well on the same computer network. This virtual domain works on its own IP subnet. I have a customer field of the database server hardware in place. This area is on a different IP subnet. I start from now all the virtual machines on a single computer. I would like to start one or two virtual machines on another computer and still be able to communicate with the virtual machines on the first computer.

  My question is how to configure the virtual machine network adapter that runs on a different computer to still be able to connect to the virtual machines on the first computer.

  This virtual network that I have is for training and for testing right now. I want to run this virtual private network inside my existing physical client server network.

  Anthony

  In order to communicate the VM must join the 'outside' world, which is possible with a network adapter or "Bridged" or "NAT". This can work, is to add a second physical NETWORK adapter to each host, configure vmnet9 as a network connected by a bridge using the second physical NETWORK adapter and connect via cross-cable or via a local network separate VIRTUAL hosts.

  Yes, we know. You said, in almost all positions, you did on this subject. We got that. Believe me, we understand that. Can we move on to solve your problem?

  Because everything counts OS logged as that doesn't have an account AUTHENTIFIE of BONES in the database.

  Enter the user name: ops Sham $
  Enter the password:
  Connected to:

  Because, despite the "ops$"... ops$ feint isn't an authenticated OS account. This is a database of authenticated account. It's only a database of authenticated account because you gave it a password. From your previous post to Justin:

  -quote from the previous post to start-

  SQL > CREATE USER ops$ sham IDENTIFIED EXTERNALLY.
  Created by the user.
  -suspend - quote

  OK, at this point, you have an authenticated os account "$ops Sham".

  -quote to continue-
  SQL > GRANT CONNECT TO the Sham ops$;
  Grant succeeded.
  -suspend - quote

  Now, the operating system account 'sham' should be able to connect with a simple "sqlplus / '.

  -quote to continue-
  SQL > grant dba to simulacrum of ops$;
  Grant succeeded.
  -suspend - quote

  Now, anyone who uses the operating system account 'sham' can connect without a password and have all the privileges listed in the role of "dba".

  -quote to continue-
  SQL > alter the simulacrum of $ ops user identified by shamos.
  Modified user.
  -end quote-

  But now change you your account "$ops Sham" and gave it a password. OPS$ feint is therefore more than a bone authenticated account. It is now a database authenticate the account, but with a rather misleading name. At this point, if you are trying to connect as "sham of the ops$", you will need to provide a password.

  I want to know the difference why this sqlplus command / error display

  Because you're tying to use authentication with an operating system account that is not an operating system os authenticated account in the database. Put "ops$" on the name of the account is NOT what makes an authenticated os account. What makes authenticated os sets the account as "identified on the outside. If you create as 'identified by somepassword', OR if you CHANGE to 'identified by somepassword' then it is NOT authenticated os.

• HA Network Configuration

  Hello

  I am currently creating a HA cluser and I was wondering what the network configuration must be for HA to work.

  What network HA uses to monitor hosts and migrate virtual machines, it is the management of the port network, where redundancy or it will use a dedicated port vmkernal configured for vMotion?

  And if I need redundant Vmkernel ports for management traffic, I can make several local networks (Layer 2) VIRTUAL, no IP address or Layer 3 configuration? I think I know the answer to that, but thought I should ask.

  ESX uses service console connection - ESXi uses the vmkernels with a check mark in "network management".

  I'm not sure that understand your second question.

• HP Envy 5540: Printer Hp Envy 5540 randomly printed the Network Configuration Page

  Hello!

  I bought this printer about a month ago. Set up the connection to the printer wireless with my wifi, and my understanding is that the printer is protected like my wifi and use the same password in order to print something. I kept my printer connected and 'standby mode' since I put in place. The night last at about 23:00 when I was in bed, the printer turned on randomly and printed a "wireless network configuration page" that has had a lot of information, including the IP address and listing my name wifi as well as the names of my neighbors wifi in the surrounding apartments.

  I'm trying to understand why this printed, because I certainly did not do. Anyone have access to my wifi, or has someone may simply try to print something and selected my printer as it should appear on the "list available connections on the computer of anyone, given that the printer is turned on? How could they print this sheet of network configuration if my printer is password protected?

  I'm mostly concerned about someone who has access to my internet if they could print this page somehow, but maybe it happened just when they tried to connect to it, and it did not work while trying to fix MY printer?

  I would appreciate any idea on the issue.

  Thank you!

  Hi @printerprob5540,

  Welcome to the HP Forums!

  I saw your post on how your HP Envy 5540 randomly print a Network Configuration Page. I'm happy to help with this problem!

  I find it very strange considering the only way to print the Network Configuration Page, AFAIK, is with the following steps:

  • Make sure that there are size A4 or US Letter, unused, plain paper in the feeder.
  • On the printer Panel, drag the screen to the left and then press Setup.
  • Touch tools.
  • Drag upward on the screen and then tap Network Configuration report.
  • A Network Configuration Page prints up to three pages of information.

  original title: grafting the internet

  Hi Maureen,

  That your router has security enabled protection?  My guess is it doesn't and it's the way that person uses your wireless connection (like someone to visit with a laptop you could if you configure).

  As a general rule, access to the router is by typing http://192.168.1.1 (or whatever your gateway address) in the address bar of your browser and you will be able to bring up the router configuration settings.  He'll probably want a username and password.  Sorry, I can't help you there because I have no idea what it could be.  Try admin/admin or admin/password or administrator/administrator or administrator/password or admin and no password or admin and no password (the classic default settings).  Your ISP or service of technical assistance of the manufacturer of the router may be able to help put this in place.  After that, how configure security entirely depends on the ISP, the router, the type of operating system you have, the type of internet connection you have and a number of other factors that I have no way to know, even if you told me that information.

  In fact, to see if this applies even, go to the Network Center and sharing, and click on manage wireless connections.  Select and double click on your network.  Click the Security tab and see if it is configured with the entries in the drop boxes first two points in the key with a password applies.  If it does not exist, then there is no security on your wireless router.  If there is, then your network is secure without doubt.

  When you see the active connection, click on start / all programs / accessories / and double click on Control Panel.  Type IPCONFIG/all and see if you can identify this other connection of the computer.  It should provide more information about it for the purpose of identification.

  If your router is not secure, you must fix and this should solve the problem.  If your router is secure, you should change the password/key of the router to see if that solves the problem (and then you will need to change the key to all your wireless computers and devices to match the new).  If it still does not work, then come back and we will come with some other ideas (assuming that the manufacturer of access provider or router cannot help you with this).

  I hope this helps.

  Good luck!
