  • Multiple External IP Ranges on a Juniper SSG5

    - by Sam
    I have a Juniper SSG 5 firewall in a datacenter. The first interface (eth0/0) has been assigned a static IP address and has three other addresses configured for VIP Nat. I have a static route configured at the lowest priority for 0.0.0.0/0 to my hosting company's gateway. Now I need to configure a second IP block. I have the IPs assigned to the second interface (eth0/1) which is in the same security zone and virtual router as the first. However, with this interface enabled I (a) can't initiate outbound sessions (browse the internet, ping, DNS lookup, etc) even though I can access servers behind the firewall just fine from the outside and (b) can't ping the management IP of the firewall/gateway. I've tried anything I can think of but I guess this is a little above my head. Could anyone point me in the right direction? Interfaces: ethernet0/0 xxx.xxx.242.4/29 Untrust Layer3 ethernet0/1 xxx.xxx.152.0/28 Untrust Layer3 Routes: http://i.stack.imgur.com/60s41.png

  • Cloud Computing - Multiple Physical Computers, One Logical Computer

    - by Koobz
    I know that you can set up multiple virtual machines per physical computer. I'm wondering if it's possible to make multiple physical computers behave as one logical unit? Fundamentally the way I imagine it working is that you can throw 10 computers into a facility one day. You've got one client that requires the equivalent of two computers worth, and 100 others that eat up the remaining 8. As demands change you're just reallocating logical resources, maybe the 2 computer client now requires a third physical system. You just add it to the cloud, and don't worry about sharding the database, or migrating data over to a new server. Can it work this way? If yes, why would anyone ever do things like partition their database servers anymore? Just add more computing resources. You scale horizontally with the hardware, but your server appears to scale vertically. There's no need to modify your application's infrastructure to support multiple databases etc.

  • CheckPoint SecuRemote / SecureClient on Vista 64

    - by cliff.meyers
    According to this page, CheckPoint's SecuRemote client is not supported on Vista 64: https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit%5FdoGoviewsolutiondetails=&solutionid=sk36681 Unfortunately in working with the systems team they will not confirm if the other two clients (SSL Network Extender or Endpoint Connect) are supported by their environment. Does anyone know if it would be possible to do the following? Install VMware Workstation on my Vista 64 system (host) install a Vista 32-bit OS in a virtual machine (guest) Install SecuRemote VPN client within the guest (Vista 32) Get my Vista 64 machine (host) to use the VPN connection from the guest Any other ideas are more than welcome.

  • XPP-32 over W7-64 on music production laptop

    - by quarlo
    I need to upgrade my laptop and need high performance for music production (recording and mixing). My audio interface manufacturer seems to be unable to successfully convert their drivers to 64-bit. I do not trust a virtual machine to handle real-time audio recording at low enough latency so ... I would like to install XP Pro 32-bit on a separate partition and dual boot since most of the machines that can handle this application now ship with Windows 7 64-bit flavors. I'd like to transit to 64-bit over time assuming M-Audio does eventually get a handle on 64-bit drivers, but really need to ensure that I can stay at 32-bit for now. Does anyone have any experience with this or something similar?

  • How does java permgen relate to code size

    - by brad
    I've been reading a lot about java memory management, garbage collecting et al and I'm trying to find the best settings for my limited memory (1.7g on a small ec2 instance) I'm wondering if there is a direct correlation between my code size and the permgen setting. According to sun: The permanent generation is special because it holds data needed by the virtual machine to describe objects that do not have an equivalence at the Java language level. For example objects describing classes and methods are stored in the permanent generation. To me this means that it's literally storing my class def'ns etc... Does this mean there is a direct correlation between my compiled code size and the permgen I should be setting? My whole app is about 40mb and i noticed we're using 256mb permgen. I'm thinking maybe we're using memory that could be better allocated to dynamic code like object instances etc...

  • How does bridged networking work?

    - by agz
    How does bridged networking work? I have looked through the virtualbox manuals but nothing extremely technical came up (It was just a generic gloss over of the topic) How does it assign a different ip to the virtual machine but uses the same network card? Why does this different ip (I found using ip addr under linux) not show up under the "attached devices section" of my router but I can port forward to it? How come if I connect to a password protected wifi network, it does not require me to enter my password? Is this multihoming?

  • Recommended CPU upgrade for Dell Vostro 220 with E7300 processor?

    - by Justin Grant
    I've got a Dell Vostro 220 with an E7300 processor (Intel Core 2 Duo @ 2.66Mhz, LGA775 socket) and I'm thinking about upgrading my processor so I can run Windows Server 2008 R2 with Hyper-V, which requires Hardware Virtualization support in the processor. Yes, I know this is underpowered for a server, I'm actually using it as a desktop machine but I'd like to use Hyper-V instead of Virtual Server (which I'm using now for running VMs). I'd like to keep the same motherboard and ideally the same CPU fan and RAM too. Any suggestions for a good, relatively cheap (under $200) processor upgrade?

  • How to set the hostname according to the DNS name on Ubuntu 9.10?

    - by tangens
    Motivation I have to manage a lot of virtual machines that I create by copying a template (VmWare image). Problem Now I have the problem that in the template the file /etc/hostname contains a given name that I want to change for each copy of the template. Facts The network interface is configured by DHCP. DNS entries exist. The system is a Ubuntu 9.10 server. Question I wonder if I can configure the template so that on startup it sets its hostname according to its DNS name. I could create an init script that parses the IP address, makes a DNS lookup and sets the hostname accordingly. But is there an easier way?

  • Problems setting up home web server

    - by putmatrix
    Has anyone been able to get a server working with the router smcwbr14t-g? Although I have been able to get Apache set up correctly and my website works on the internal IP 192.168.2.101, I've been running into a dead end when trying to get it to show up on my external IP. In my router, there is no option for port forwarding, but there are options for a 'virtual server'. Following the manual, I have it set up like this: http://imgur.com/zrcV7.png I also disabled the firewall. I configured Apache to listen to ports 80, 81, and 443, none of which solved the problem. However, the IP's 192.168.2.101:443 and :81 load fine. The problem is that I still cannot load the web site from my external IP, either from my computer or outside.

  • Dual boot Windows 7 with Windows 8- Dynamic Disk

    - by MeetM
    Its a long explanation. I have a HP Pavilion dm4 notebook. It has pre installed Windows 7 Home Pre. Recently, I tried to install Windows 8 developer preview on my notebook, but while installing, it only allowed me to insatll it on my primary Windows 7 drive I.e. drive C. I had kept 1 empty partition for Windows 8 but when I selectced that option, the next button at the bottom of the window just grey with some error saying Windows cannot boot from this drive....blah blah blah So I googled and found another way of doing it by VHD(virtual hard disk). This seemed to work but on restarting gave me "VHD_BOOT_INITIALIZATION_FAILED" error. After trying all possible ways for around 10 times, I gave up. I noticed that d only thing difference in d tutorials and my notebook is the Disk type. They all had Basic and I have Dynamic. Is that the reason m not able to boot Windows 8? Any suggestions?

  • Emacs saying: <M-kp-7> is undefined when dictating quotes with Dragon naturally speaking 12

    - by Keks Dose
    I dictating my text via Dragon Naturally Speaking 12 into Emacs. Whenever I say (translation from German): 'open quotes', I expect something like " or » to appear on the screen, but I simply get a message <M-kp-2> is undefined . Same goes for 'close quotes', I get <M-kp-7> is undefined. Does anybody know how to define those virtual keyboard strokes? (global-set-key [M-kp-2] "»") does not work.

  • Converting a VMware player image from non-persistant to persistant

    - by Journeyman Geek
    I'm pondering setting up a virtual machine to generate app-v (since i got mdop from school) or thinapp application virtualisation packages. Ideally with either of these, i should work off a fresh system do the install, then copy out the packages produced. I'd like to not have to reinstall windows per package to get a fresh, unmodified stock copy of windows. I'm aware that its possible to make a hard disk image persistant in vmware player (one of my lecturers did it, but he's in another country). I'm wondering how would i convert a persistant image to a non persistant one? I'm currently running vmware player 4, with windows 7 guest and host.

  • Compiling the Linux kernel, how much size is needed?

    - by ant2009
    I have downloaded the newest most stable Linux kernel, 2.6.33.2. I thought I would test this using VirtualBox. So I create a dynamically sized harddisk of 4 GB. And installed CentOS 5.3 with just the minimum packages. I setup the make menuconfig with just the default settings. After that I ran make and got the following error: net/bluetooth/hci_sysfs.o: final close failed: No space left on device make[2]: *** [net/bluetooth/hci_sysfs.o] Error 1 make[1]: *** [net/bluetooth] Error 2 make: *** [net] Error 2 The amount of space I have left is: # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 3.3G 3.3G 0 100% / /dev/hda1 99M 12M 82M 13% /boot tmpfs 125M 0 125M 0% /dev/shm My virtual size is 4 GB, but the actual size is 3.5 GB. $ ls -hl total 7.5G -rw-------. 1 root root 3.5G 2010-04-13 14:08 LFS.vdi How much size should I give when compiling and installing a Linux kernel? Are there any guidelines to follow when doing this? This is my first time, so just experimenting with this.

  • Openfiler RAID 10 option not found

    - by chrisling106
    Hi, I'm building a NAS using Openfiler2.3 (from 32-bit ISO), first of all I want to experiment it on VM first before going out and buy the harddrives needed. I created 5 virtual drives on VMware, sda is 2GB and the rest 1GB each (sdb to sde). I left sda blank and want to setup a RAID 10 disk using sdb, sdc, sdd and sde, 4 RAID partitions are setup successfully, but when I try to create a RAID device the only option for RAID level is 1, 0, 5 and 6. RAID 10 is not there! Can someone let me know what have I missed, please? TIA.

  • Task Manager: VM Size smaller than Mem usage?

    - by shoosh
    The windows XP tasks manager can show two different columns regarding the memory usage of the processes. One is called Mem Usage and the other is VM Size (not on by default, you need to activate it) From what I've gathered, VM size is the size of the entire memory space occupied by the process and Mem Usage is the amount of memory currently committed and used. This assumption is verified by most processes when the VM Size is only slightly larger than Mem Usage for instance my Outlook currently has 79,724 K in VM Size and 56,600 K in Mem Usage But it fails for other processes such as Firefox which currently has 171,900 K for Mem Usage and only 156,440 K in VM Size. How can a process use more memory than the amount of virtual memory allocated to it? So Maybe my interpretation of these columns is wrong. What do they actually mean?

  • Webkit based browsers on Mac refuse to load certain websites or resources, other browsers work fine from the same machine

    - by BergQuester
    OK, this one has really been puzzling me. Certain websites (such as instapaper.com ) or certain resources (such as the CSS and images for icanhazcheezeburger.com sites) refuse to load at all in Safari or Chrome on any of my Mac machines. Rebooting the machine doesn't fix it. If I use another browser, such as Firefox or a browser on my iPhone or in my Windows virtual machine, the pages load just fine. When the whole page errors out, Safari displays an error: "WebKit encountered an internal error" WebKitErrorDomain:300 This is all from within my home network. Any ideas what could possibly be causing such bizarre behavior?

  • What is the correct configuration for multiple apache2 vhosts and multiple php5-fpm pools?

    - by farinspace
    I have a group of sites (group A) which I would like to run using one php5-fpm pool and a second group of sites (group B) which I would like to run using a second php5-fpm pool. I can effectively define/create the pool in the fpm.conf file and I confirmed that it is running with the different user/group I've defined. However I am unclear as to how to setup the apache virtual host config. I've tried a few apache2 configurations but I seem to not be able to add the second pool. If you've done this please help.

  • Error installing Network driver

    - by Simon Carpentier
    I'm tring to install NetLimiter 3 (3.0.0.10, x64) on my Windows 7 x64 machine. At the driver installation step, I'm getting an error: Error 0x8004a029: Couldn't install the network component. (InstallNdisIMDriver) UPDATE 2010-09-20: I received a response to my support request: Hi Simon, It seems that problem is rather on your system than in NL3. Too many networking applications (VPN, Virtual computers) are installed on your machine and they are preventing NL3 from proper installation. In order to install NetLimiter 3, try to disable/temporarily remove these apps. Several users had the same problem and shuffling with adapter and networking software helped them. Please, let us know which action helps you (if any). Sincerely, Jan Bilek Any thoughts on this?

  • Remotely managing Hyper-V VMs from Windows 8 Client

    - by Vazgen
    Currently, I have a core Hyper-V Server hosting VMs for a domain controller and several domain-joined VDI infrastructure servers. The VMs are connected in that domain environment, but the remote management of the physical Hyper-V Server is set up using the same WORKGROUP (as the Windows 8 client I'm managing from) This makes it cumbersome to manage the VMs hosted on the physical server from my remote management Windows 8 client because I can only connect to the physical Hyper-V server and not the individual VMs hosted inside. Can I make my set up more flexible by hosting a second domain controller in a VM hosted on my Windows 8 machine and switching my remote management set up to use the same domain through? Meaning ALL physical and virtual machines including the VDI infrastructure under the same domain? I'm new to this just looking for some suggestions.

  • Virtualbox and Serial Port permissions

    - by Pandincus
    I have a Windows XP Pro SP3 host machine running a Windows XP Pro SP3 guest machine. The host machine has one serial port, COM1, that I need to use in the guest machine. When I add the serial port to the guest machine and try to start it, I get the following error: Failed to start the virtual machine xxx Cannot open host device 'COM1' for read/write access. Check the permissions of that device (VERR_ACCESS_DENIED). Unknown error creating VM (VERR_ACCESS_DENIED). What are some of the things that might be causing this problem? How can I check "permissions" on a serial port?

  • An SQLite/STDIN Conundrum, Specific to AIX

    - by mikfreedman
    Hi there! I'm been playing around with SQlite at work, specifically with trying to get the sqlite3 command line tool to accept stdin instead of a file. Sounds easy enough, on linux you can execute a command like: echo 'test' | sqlite3 test.db '.import /dev/stdin test' unfortunately - our machines at work run AIX (5 & 6) and as far as I can tell, there is no equivalent to the virtual file /dev/stdin. I managed to hack together an equivalent command that works on AIX using a temporary file. echo 'test' | cat - > /tmp/blah ; sqlite3 test.db '.import /dev/stdin test' ; rm /tmp/blah Now, does it need to use STDIN? isn't this temporary file thing enough? Probably, but I was hoping someone with better unix-fu had a more elegant solution. note: the data I would like to import is only provided via STDOUT, so that's what the echo 'test' command is all about
