  • Securing a Cloud-Based Data Center

    - by Orgad Kimchi
    No doubt, with all the media reports about stolen databases and private information, a major concern when committing to a public or private cloud must be preventing unauthorized access of data and applications. In this article, we discuss the security features of Oracle Solaris 11 that provide a bullet-proof cloud environment. As an example, we show how the Oracle Solaris Remote Lab implementation utilizes these features to provide a high level of security for its users. Note: This is the second article in a series on cloud building with Oracle Solaris 11. See Part 1 here.  When we build a cloud, the following aspects related to the security of the data and applications in the cloud become a concern: • Sensitive data must be protected from unauthorized access while residing on storage devices, during transmission between servers and clients, and when it is used by applications. • When a project is completed, all copies of sensitive data must be securely deleted and the original data must be kept permanently secure. • Communications between users and the cloud must be protected to prevent exposure of sensitive information from “man in a middle attacks.” • Limiting the operating system’s exposure protects against malicious attacks and penetration by unauthorized users or automated “bots” and “rootkits” designed to gain privileged access. • Strong authentication and authorization procedures further protect the operating system from tampering. • Denial of Service attacks, whether they are started intentionally by hackers or accidentally by other cloud users, must be quickly detected and deflected, and the service must be restored. In addition to the security features in the operating system, deep auditing provides a trail of actions that can identify violations,issues, and attempts to penetrate the security of the operating system. Combined, these threats and risks reinforce the need for enterprise-grade security solutions that are specifically designed to protect cloud environments. With Oracle Solaris 11, the security of any cloud is ensured. This article explains how.

  • vmware player won't run on CentOS due to missing /dev/vmmon, what could be the problem?

    - by Graphics Noob
    So I've tried installing vmware player 3.1.4 and 3.1.3 and both times had the same problem, when I try to load a VM I get the error "Could not open /dev/vmmon". When I ls /dev/ I can see there is no "vmmon" device present. When I try running: sudo /etc/init.d/vmware start I get the output: Starting VMware services: VMware USB Arbitrator [ OK ] Virtual machine monitor [FAILED] Virtual machine communication interface [ OK ] VM communication interface socket family [ OK ] Blocking file system [ OK ] Virtual ethernet [FAILED] which shows that the Virtual Machine Monitor fails to load. I tried following the advice on this site and ran vmware-modconfig --console --install-all I notice during the compilation there are no errors, but at the end I get the message: Starting VMware services: VMware USB Arbitrator [ OK ] Virtual machine monitor [FAILED] Virtual machine communication interface [ OK ] VM communication interface socket family [ OK ] Blocking file system [ OK ] Virtual ethernet [ OK ] Unable to start services Out of curiousity I tried: sudo /sbin/insmod /lib/modules/2.6.18-238.9.1.el5xen/misc/vmmod.ko But got the error message: insmod: error inserting 'vmmon.ko': -1 Invalid module format I have a feeling this may be the root of the problem, but I don't know what could be causing it or how to fix it.

  • What methods are available for updating a non-Internet-connected VMWare ESXi host?

    - by romandas
    I have a stand-alone installation of VMWare vSphere Essentials, with a vCenter Server and 3 ESXi 4.0 host servers. The environment is intended to remain as a stand-alone network, with the exception that I can "float" a workstation or server between the 'Net and the VMWare network for patches and maintenance. With other installations, where the Internet is available, I've used the vSphere Host Update utility to connect to VMWare and then apply the patches to the ESXi hosts. My problem is that this utility does not seem to function if it cannot connect to both VMWare and the ESXi host at the same time, as the scan for patches function will not scan the server without connecting to VMWare's site to sync its repository first. Even if I sync it, disconnect from the 'Net and connect to the VMWare network, it still won't scan hosts for required patches -- it will prompt for syncing with VMWare and if you click No to syncing, the scan does not occur. Does anyone know of other options for updating the ESXi hosts in some automated fashion? I believe I can manually pull down required patches and apply them, but this will not scale well, and in the future I'm sure I'll want something a bit more scalable.

  • Leaks on Wikis: "Corporations...You're Next!" Oracle Desktop Virtualization Can Help.

    - by adam.hawley
    Between all the press coverage on the unauthorized release of 251,287 diplomatic documents and on previous extensive releases of classified documents on the events in Iraq and Afghanistan, one could be forgiven for thinking massive leaks are really an issue for governments, but it is not: It is an issue for corporations as well. In fact, corporations are apparently set to be the next big target for things like Wikileaks. Just the threat of such a release against one corporation recently caused the price of their stock to drop 3% after the leak organization claimed to have 5GB of information from inside the company, with the implication that it might be damaging or embarrassing information. At the moment of this blog anyway, we don't know yet if that is true or how they got the information but how did the diplomatic cable leak happen? For the diplomatic cables, according to press reports, a private in the military, with some appropriate level of security clearance (that is, he apparently had the correct level of security clearance to be accessing the information...he reportedly didn't "hack" his way through anything to get to the documents which might have raised some red flags...), is accused of accessing the material and copying it onto a writeable CD labeled "Lady Gaga" and walking out the door with it. Upload and... Done. In the same article, the accused is quoted as saying "Information should be free. It belongs in the public domain." Now think about all the confidential information in your company or non-profit... from credit card information, to phone records, to customer or donor lists, to corporate strategy documents, product cost information, etc, etc.... And then think about that last quote above from what was a very junior level person in the organization...still feeling comfortable with your ability to control all your information? So what can you do to guard against these types of breaches where there is no outsider (or even insider) intrusion to detect per se, but rather someone with malicious intent is physically walking out the door with data that they are otherwise allowed to access in their daily work? A major first step it to make it physically, logistically much harder to walk away with the information. If the user with malicious intent has no way to copy to removable or moble media (USB sticks, thumb drives, CDs, DVDs, memory cards, or even laptop disk drives) then, as a practical matter it is much more difficult to physically move the information outside the firewall. But how can you control access tightly and reliably and still keep your hundreds or even thousands of users productive in their daily job? Oracle Desktop Virtualization products can help.Oracle's comprehensive suite of desktop virtualization and access products allow your applications and, most importantly, the related data, to stay in the (highly secured) data center while still allowing secure access from just about anywhere your users need to be to be productive.  Users can securely access all the data they need to do their job, whether from work, from home, or on the road and in the field, but fully configurable policies set up centrally by privileged administrators allow you to control whether, for instance, they are allowed to print documents or use USB devices or other removable media.  Centrally set policies can also control not only whether they can download to removable devices, but also whether they can upload information (see StuxNet for why that is important...)In fact, by using Sun Ray Client desktop hardware, which does not contain any disk drives, or removable media drives, even theft of the desktop device itself would not make you vulnerable to data loss, unlike a laptop that can be stolen with hundreds of gigabytes of information on its disk drive.  And for extreme security situations, Sun Ray Clients even come standard with the ability to use fibre optic ethernet networking to each client to prevent the possibility of unauthorized monitoring of network traffic.But even without Sun Ray Client hardware, users can leverage Oracle's Secure Global Desktop software or the Oracle Virtual Desktop Client to securely access server-resident applications, desktop sessions, or full desktop virtual machines without persisting any application data on the desktop or laptop being used to access the information.  And, again, even in this context, the Oracle products allow you to control what gets uploaded, downloaded, or printed for example.Another benefit of Oracle's Desktop Virtualization and access products is the ability to rapidly and easily shut off user access centrally through administrative polices if, for example, an employee changes roles or leaves the company and should no longer have access to the information.Oracle's Desktop Virtualization suite of products can help reduce operating expense and increase user productivity, and those are good reasons alone to consider their use.  But the dynamics of today's world dictate that security is one of the top reasons for implementing a virtual desktop architecture in enterprises.For more information on these products, view the webpages on www.oracle.com and the Oracle Technology Network website.

  • Can I minimize VMWare Workstation from exclusive mode?

    - by Blorgbeard
    I am running a VM on two monitors, in fullscreen exclusive mode. I would like to be able to minimize the VM and mess around in the Host, then go back to the VM. I can do this by pressing CTRL+ALT to get out of fullscreen mode, but this puts the VM back onto a single monitor, which moves all my VM's windows back to the main virtual screen. This is annoying, because when I come back to the VM, I have to go back to multiple monitor mode, and move windows back to where they should be. Is there a way to temporarily escape from fullscreen exclusive mode, without disturbing multi-monitor layout? I should note that I'm only using exclusive mode to get rid of the popup toolbar that otherwise appears when your mouse gets too close to the top of the screen. If there's another way to kill that, please let me know. My host and guest are both Windows 7 x64, and I'm running VMWare Workstation 8.

  • Troubleshooting PXE-E11: ARP Timeout error under VMware ESXi 4 and HPSA 7.8

    - by warren
    I am running HP Server Automation v7.8 in a lab environment on VMware ESXi, managed via vSphere 4. On the same host I have several small VMs for OS provisioning testing (512MB RAM, 10GB hdd, one NIC on the same vSwitch that HPSA is running on). DHCP is configured to hand-out addresses in the 192.168.10.151-200 range. On boot of the VM, it receives an IP (eg 192.168.10.198) within seconds. However, after it receives its IP, a PXE-E11: ARP Timeout error occurs in trying to boot from the DHCP server. I do not know if this is a HPSA-specific error, as I have seen reports of the PXE-E11 error on various forums. Proposed solutions I have seen so far (changing VLAN settings, for example) have not been applicable to my environment. Are there any pointers/troubleshooting steps that can be taken to resolve this?

  • Getting a VMnet0 error in VMWare workstation after updating host computer from Windows 8 to 8.1

    - by Andrew
    Yesterday, I updated my computer from Windows 8 to 8.1. I have VMWare Workstation 10 running Windows XP on this computer and prior to the update I had no issues connecting to my network. However, since updating, I haven't been able to connect to any network and I'm getting the following error: "The network bridge on device VMnet0 is not running. The firtual machine will not be able to communicate with the host or with other machines on your network. Failed to connect virtual device Ethernet0" I've checked all of my settings which currently have my network adapter set for a bridged connection and under device status "connected" is checked. Not really sure where to go from here, but after doing some research I have seen that others users have reported getting this error when updating the OS (any OS, not windows 8 specifically) of the host computer. Thanks in advance to anyone who can help.

  • Growing the size of a VM's disk in VMware

    - by soandos
    I have a VM that I originally gave 10 GB to (using VMware workstation, and Ubuntu 11.10 is the guest OS). I now wish to add to that. I have seen the option to expand the disk size, but all that does is create a new "partition" that Ubuntu can see. Is there a way to expand the size of the primary partition that the guest OS is using? NOTE: I have seen something regarding doing this for a regular Ubunbu OS that requires a boot disk. Is there a way that I can apply that to this VM case? Using Windows 7 64-bit as the host OS EDIT: To be clear, I am trying to resize the boot partition. Edit 2: GParted's resize option is greyed out.

    - by hoberion
    ok, this is really pissing me off I have one ubuntu 8.04 instance running on vmware (esx) which decided after a reboot to stop resolving dns requests, I also cant connect to it using ssh although I can ping the server and its really that server (when I shutdown the server the ping also stops) stuff I tried: - reboot again :) - nslookup - serverip - setting networking to dhcp - offering some cute kittens to lucifer - removing the virtual nic and adding another (to get a different mac) - migrating the instance to another esx host - drinking 20 cups of espresso - stopped all services - running dnsmasq on another server and connecting to that dns - tcpdumping - disabling ip6 symptoms: cant resolve anything nslookup just says "no servers found..." although I can ping the servers traceroute to gateway doesnt work (even with traceroute -4 -n gatewayip) collegues laughing at me any thoughts

  • VMWare Fusion - Cannot communicate between Host Mac and Virtual Mac running on same machine [migrated]

    - by Jeff Gold
    I'm running a "virtual" Mac OS machine on a Mac running VMWare Fusion. The Virtual Mac is setup with Bridged Networking, and has its own separate IP address. The outside world can connect to either the Mac itself or the virtual Mac via their respective IP addresses just fine, this works great! The problem... the Mac itself cannot connect to the virtual Mac's IP address, nor can the virtual Mac connect to the real Mac's IP address. Some things I've read mention something about enabling VMCI, but I have no idea how to do this, or if this is even the correct solution. Any suggestions?

  • Slow network file access with VMWare Server and Windows 7

    - by garethm
    I have Windows 7 32-bit virtual machine running in a VMWare Server virtual machine. The host is Windows 7 64-bit. When I copy files between them it is extremely slow - it will take several minutes to copy even a 1 MB file. I can upload the file to an website and then download it again almost instantaneously by comparison. Browsing the network is quite zippy and has no problems. I have been unable to set up a HomeGroup between the computers though - the guest always times out without managing to get setup. Any ideas on how I should go about tracking down where the problem is?

  • Create Vmware image from exisiting Ubuntu installation

    - by Tathagata
    I have been stuck on a netbook since last year due to budget constraints, but finally managed to get a decent laptop from a very generous person. Now my ubuntu installation in the netbook has all my development tools, libraries, personal mediawiki, other servers and things that I'm only reminded when the command line complains. I can always ssh into my netbook, but don't want to carry both the computers all the time. Is it possible to create an image from my netbook Ubuntu and use it out of the box in a Vmware player in the new laptop?

  • Nested RDP and ILO/VMWare console sessions, latency and keystroke repetition

    - by ewwhite
    I'm working on a remote server installation entirely through ILO. Due to the software application and environment, my access is restricted to a Windows server that I must access through RDP. Going from that system to the target server is accomplished via HP ILO2 or ILO3. I'm trying to run a CentOS installation in an environment where I can't use a kickstart. I'm doing this via text mode, but the keystrokes are repeating randomly and it's difficult to select the proper installation options. For example: ks=http://all.yourbase.org/kickstart/ks.cfg ends up looking like: ks====httttttp://allll..yourbaseee.....org/kicksstart/ks.cccfg I'm doing this using Microsoft's native RDP client (on Mac and Windows). I've also noticed this before when running installations or doing remote work in nested sessions. Same for typing into a VMWare console in some cases. Is there a nice fix for this, or it it simply a function of the protocol(s)?

  • Vagrant with VMware ESXi Provider

    - by Adam
    I am attempting to work with Vagrant and the vagrant-vsphere plugin to deploy machines to my VMware ESXi server. Has anyone had any luck in getting this to work? I realize that vagrant-vsphere is still 0.0.1 though and there are bound to be bugs. Specifially, Vagrant and vagrant-vsphere appear to fail during the vsphere connection, however, SSH and CLI access is enabled and the vSphere powershell is able to connect without an issue. INFO warden: Calling action: # ERROR warden: Error occurred: VagrantPlugins::VSphere::Errors::VSphereError The hostd log file on the ESXi server shows the Vagrant doing an SearchIndex query.

  • VMWare - persistent "Host memory status" alarm in vSphere

    - by ewwhite
    I have a particular VMWare ESX 4.1 host that has a very persistent "Host memory status" alarm. This is running on an HP ProLiant DL360 G7 server. The HP ILO and System Management agents don't know any errors. If I clear the alarm in the vSphere client, it returns within a day. I've tried reseating DIMMs, however, the error does not indicate a problem with a specific module. There's another host in the cluster with an identical configuration. It's not exhibiting any issues. Any thoughts? This is touched on briefly on other forums (and here) with no clear resolution.

  • VMware networking - PortChannel or not?

    - by dunxd
    My ESX hosts each have 8 NICS. I have set up 2 NICs for our iSCSI SAN - each is connected to a different SAN switch. 2 NICs are set up for vMotion and Service Console - these are each connected to a different core switch (ports are trunked with VLANs dedicated to vMotion and Management) I now have four ports left over. Currently we have these set up each going into our default VLAN. Two NICs are connected to one core-switch and two are connected to the other. We decided to aggregate the connections to each switch - so they are teamed at the vswitch end, and port channelled at the physical switch end. I am now reading that port channelling these connections is not particularly useful, perhaps even over complicating things. Is there a particular problem with using port channels for VMware? What method provides the best balance between redundancy and performance?

  • VMware ESXi - vSphere - Can't exit VM console access

    - by caleban
    I'm running ESXi 4.1 on a Dell T110 Server I connect to ESXi using vSphere vSphere is running inside a Windows 7 VM The Windows 7 VM is running in VMware Fusion on my Mac OS X system When I'm in vSphere and I've selected a VM and I click the console tab on some systems the VM console won't release me when I press the control + command keys. pfSense (FreeBSD) and Ubuntu Server behave like this. I can't exit their console screen. I have to shut down these VM's to be released from their VM console access. Windows, Ubuntu Desktop, etc. all behave like I'd expect; When I press the control + command keys I'm released from the VM console and I'm able to navigate in vSphere. Does anyone know what might be causing this or a way around this? Thanks in advance.

  • Vmware sphere setting up external network

    - by Tom Beech
    I've just setup vmware vsphere 5 on a remote server (rented dedicated server). I've added my first VPS (centos 5.8) barebones. It's not finding any IP (internal or external) on boot. I've had an extra external IP assigned to my server that I wanted to use on the VPS. I tried editing the eth0 config and adding the IP in there and turning off the DHCP, but it can't find any IP or ping google or do any networking type things. How do I route the IP to my VPS so I can access it remotely?

  • Mac OS X: pushing all traffic through a VMWare VM [closed]

    - by bj99
    I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

  • SNMP - Value of CPU processor load not reflecting reality

    - by Ovesh
    Trying to plot CPU load on my server, with the following hardware: ProLiant DL360p Gen8 (same behavior on ProLiant DL360 G7). The machine is running VMWare ESXi5.1 To create a CPU spike I run dd if=/dev/zero of=/dev/null, and I know the CPU is overloaded, because I can see a correlating spike in the graphs displayed on vCenter. However, running this snmpwalk: snmpwalk -v 1 -c ******** 192.168.MY_IP 1.3.6.1.2.1.25.3.3.1.2 Shows the following results: iso.3.6.1.2.1.25.3.3.1.2.1 = INTEGER: 3 iso.3.6.1.2.1.25.3.3.1.2.2 = INTEGER: 2 iso.3.6.1.2.1.25.3.3.1.2.3 = INTEGER: 2 iso.3.6.1.2.1.25.3.3.1.2.4 = INTEGER: 3 Am I not looking into the right MIB? Should I be multiplying these by a constant? By the way, using HP Agentless Monitoring I was able to get some cpu stats, but not what I'm looking for, at least nothing I could find wading through these MIBs.
