  • Easy_install the wrong version of python modules (Mac OS)

    - by user73250
    I installed Python 2.7 on my Mac. When typing "python" in terminal, it shows: $ python Python 2.7 (r27:82508, Jul 3 2010, 20:17:05) [GCC 4.0.1 (Apple Inc. build 5493)] on darwin Type "help", "copyright", "credits" or "license" for more information. The Python version is correct here. But when I try to easy_install some modules. The system will install the modules with python version 2.6 which are not able be imported to Python 2.7. And of course I can not do the functions I need in my code. Here's an example of easy_install graphy: $ easy_install graphy Searching for graphy Reading pypi.python.org/simple/graphy/ Reading http://code.Google.com/p/graphy/ Best match: Graphy 1.0.0 Downloading http://pypi.python.org/packages/source/G/Graphy/Graphy- 1.0.0.tar.gz#md5=390b4f9194d81d0590abac90c8b717e0 Processing Graphy-1.0.0.tar.gz Running Graphy-1.0.0/setup.py -q bdist_egg --dist-dir /var/folders/fH/fHwdy4WtHZOBytkg1nOv9E+++TI/-Tmp-/easy_install-cFL53r/Graphy-1.0.0/egg-dist-tmp-YtDCZU warning: no files found matching '*.tmpl' under directory 'graphy' warning: no files found matching '*.txt' under directory 'graphy' warning: no files found matching '*.h' under directory 'graphy' warning: no previously-included files matching '*.pyc' found under directory '.' warning: no previously-included files matching '*~' found under directory '.' warning: no previously-included files matching '*.aux' found under directory '.' zip_safe flag not set; analyzing archive contents... graphy.all_tests: module references __file__ Adding Graphy 1.0.0 to easy-install.pth file Installed /Library/Python/2.6/site-packages/Graphy-1.0.0-py2.6.egg Processing dependencies for graphy Finished processing dependencies for graphy So it installs graphy for Python 2.6. Can someone help me with it? I just want to set my default easy_install Python version to 2.7.

  • Network Misconfiguration when adding first host to new vSphere cluster

    - by dunxd
    I am building a new vSphere cluster from scratch. I have installed ESXi on the first host, and built a vCenter server on a VM residing on that host (storage is on the local hard drive, although we have iSCSI targets which I can reach from the host). The cluster is configured for HA. When I try and add the host to the cluster, I get an error at the point where HA is configured - Cannot complete the . I have stripped the network configuration of the host down to the most basic - a single NIC attached to a single vSwitch - this is running the VMKernel Port on VLAN 8 - that is our Management VLAN. The vCenter server will have a network address on this VLAN, so I also set the initial Virtual Machine Port Group to this VLAN, and connected the vCenter server NIC to this port group. I understand I can't connect the vCenter server to the VMkernel port group, but shouldn't I be able to connect the vCenter server to a Port Group in the same VLAN? If not, do I need to create a VLAN specifically for VMKernel Port Group? I plan to set up another port group for vMotion with a dedicated and isolated VLAN (i.e. VLAN isn't routed) so this wouldn't allow vCenter to communicate. Does anyone have any suggestions, or other ideas for what might be causing the problem. I've read through the documentation, but it isn't giving me any pointers, and the error message isn't helping me beyond telling me something is wrong with my network config.

  • How do I hook into Tar with BASH?

    - by orb
    Long Story Short I am working with Tar archives that contain PNG images in base64 encoding. I would like to use BASH (or whatever else works) to hook into the extraction function of Tar to decode PNG images from base64 encoding to standard PNG encoding after the files are unpacked. A simple cat $input-file | base64 -d >$output-file will successfully decode the images. Is there a way I can hook into tar -xf so that users do not have to do any (or minimal) extra work to decode the images? In the GNU Tar documentation (http://www.gnu.org/software/tar/manual/html_chapter/Backups.html#SEC97) I found that there are in fact variables reserved to hold the names of functions I desire to be hooked into various moments in Tar program execution. However, the documentation explains that these variables, along with other variables that can be set to configure Tar, are located in a file named backup-specs. Unfortunately, the path to this file is not given. Further, running sudo find / -name backup-specs tells me that this file is not present on my Ubuntu version 13.04 system. Background Information not included in the Long Story Short I have been working on a browser-based (WebGL) particle effect creation application (http://www.particleeffect.org), (https://github.com/cgrabowski/webgl-particle-effect-editor), (https://github.com/cgrabowski/webgl-particle-effect). I have began to write a client-side-only solution for saving and loading effect data as a tar archive. However, since client-side JavaScript has limited capability to process binary data, the images used as textures in the effect are saved with base64 encoding. I have been able to implement saving effect data as a Tar archive (haven't pushed that to Github yet). However, the images present in said Tar archive cannot be manipulated unless they are decoded from base64 encoding.

  • Different network response for indentical co-located machines

    - by Santosh
    We have a situation as follows: We have a two different virtual machines (VMs) on some remote server farm. The machines are identical in terms of hardware/software(OS) configurations. We have a J2EE application running on JBoss on each of those two machines. These two applications are of different version sav V1 on VM1 and V2 on VM2. We observed some degraded response time for application V2 when accessed via public URL. When we accessed the application through a secured VPN, there is hardly any difference. The bandwidth test (upload/download speed, ping etc) shows that VM1 is responding better when accessed via secured VPN. We concluded that the application does not seem to have performance issue. Because, it that's the case the performance degradation should also be there when access via VPN. So we concluded its the network problem. But since those two identical VMs are on same network we are looking for the reasons for different responses. My question is, given the above situation, what could be reasons for such a behavior ?

  • Windows Remote Desktop: "configuring remote session" closes without error

    - by icelava
    I have a desktop/laptop pair at home operating x64 Windows 7 (the desktop was upgraded from Windows Vista, works just fine). I remote desktop to them on a daily basis when outside. In recent weeks, I would occasionally fail to connect to my desktop. It can connect and authenticate fine, but the "configuring remote session" dialog would simply close and not show me the desktop window or any error message. There is no error event log relating to this on the desktop computer. Some suggestions call for disabling remote audio, which mine already is, but trying different audio modes did not yield any different result. I am not too sure if this is related to video card drivers (they do get auto-updated), since remote desktop video is supposed to steer via a virtual device driver? Nonetheless the desktop operates three monitors via an ATI Radeon HD5770 (1 Displayport, 2 DVI). I do not see a real problem with that since I can mostly connect and operate it remotely. I try to "remote tunnel" via my home laptop but obviously won't work either as the problem lies in the desktop. What other conditions can cause remote desktop to break without error? UPDATE I came home and still couldn't connect to the desktop until I restarted the entire system.

  • Are there cloud network drives that let users lock files or mark them as "in use"?

    - by Brandon Craig Rhodes
    Having spent several hours reading about the features and limitations of services like DropBox and Jungle Disk and the hundreds of competitors they seem to have (as though everyone with an AWS account these days goes ahead and writes a file sharing application just for fun), I have yet to find one that would let a team of people at a small business collaborate without stepping all over each other's toes. At a small business there are often many small documents per project — estimates, contracts, project plans, budgets — and team members frequently have to open and edit them, with all sorts of problems happening if two people edit a file at once. Even if a sharing service is smart enough to keep both versions of the file created, most small-business software (like word processors, spreadsheets, estimating software, or billing systems) has no way to compare — much less to merge! — the changes in two rival versions of a file that two people edited at the same time without each other's knowledge. So, my question: are their cloud-based file sharing solutions that not only provide a virtual network drive that people can access, but that also let users lock files — even if it's not a real lock but just a flag or indicator — that could possibly prevent remote workers from both editing the same file at once? Having one person wait for another person to finish editing is a very, very small inconvenience compared to the hour or more than it can take to compare two estimates by hand until you find and resolve the rival changes. Given this fact, I am surprised that almost none of the popular file sharing solutions seem to recognize this problem and provide some solution! Does anyone know of a service that does?

  • Macbook Pro - 15" with i7 processor - Any problems with heat?

    - by webworm
    You may have already heard about the review done by the folks at PC Authority in Australia, where they had an i7 MacBook Pro that got up to 100 degrees Celsius during benchmarking. Here is the URL in case you have not read it. http://www.pcauthority.com.au/News/172791,macbook-pro-helps-core-i7-hit-100-degrees.aspx In any case, I was considering purchasing a 15" Macbook Pro with the i7 processor and the NVIDIA GeForce GT330M with 512 video memory. Having read how hot the computer got I started to become hesitant about purchasing. My main concern is long term damage to the computer due to excessive heat. I plan to use the MacBook Pro as a development machine where I will be running Windows 7 within VMWare Fusion or Virtual Box. Within the VM I will be running IIS, SQL Server, Visual Studio and SharePoint Server. Hence why I would like to have the power of the i7 processor. That is why I wanted to check with actually owners of the MacBooks with the i7 processor and see what their experiences have been. Have you noticed excessive heat? How does your Macbook handle process intensive apps over long periods of time? Thank you!

  • Linux/Unix in Windows

    - by Dmitriy Nagirnyak
    Hi, What would be the best way to get the full-blown Unix/Linux bash inside Windows? I don't mean the Virtual Machine, but rather only the terminal with mounted NTFS drives. This way I could use the power of Unix/Linux still being on Windows. The things I want to be able to do from the terminal: Package management (apt-get in Debian). SSH. File operations (including grub and similar). Run a web server (Apache, nginx) for testing purposes. Easy to use: start terminal - Linux is on, end terminal - Linux is shut down. Would be nice to be able to copy-paste from Windows into Terminal and vice versa. This really feels like a separate OS and I realize that VM would, probably, be the best thing. But I guess it should be possible to have a lighter installation. THE NOTE: I cannot just use Linux because of I still need to do development on Windows. Also I am a Linux noobie - just getting started with it so sorry if asking something obvious/stupid. Thanks, Dmitriy.

  • Proper way to use hiera with puppetlabs-spec-helper?

    - by Lee Lowder
    I am trying to write some rspec tests for my modules. Most of them now use hiera. I have a .fixures.yml: fixtures: repositories: stdlib: https://github.com/puppetlabs/puppetlabs-stdlib.git hiera-puppet: https://github.com/puppetlabs/hiera-puppet.git symlinks: mongodb: "#{source_dir}" and a spec/classes/mongodb_spec.rb: require 'spec_helper' describe 'mongodb', :type => 'class' do context "On an Ubuntu install, admin and single user" do let :facts do { :osfamily => 'Debian', :operatingsystem => 'Ubuntu', :operatingsystemrelease => '12.04' } end it { should contain_user('XXXX').with( { 'uid' => '***' } ) should contain_group('XXXX').with( { 'gid' => '***' } ) should contain_package('mongodb').with( { 'name' => 'mongodb' } ) should contain_service('mongodb').with( { 'name' => 'mongodb' } ) } end end but when I run the spec test, I get: # rake spec /usr/bin/ruby1.8 -S rspec spec/classes/mongodb_spec.rb --color F Failures: 1) mongodb On an Ubuntu install, admin and single user Failure/Error: should contain_user('XXXX').with( { 'uid' => '***' } ) LoadError: no such file to load -- hiera_puppet # ./spec/fixtures/modules/hiera-puppet/lib/puppet/parser/functions/hiera.rb:3:in `function_hiera' # ./spec/classes/mongodb_spec.rb:15 Finished in 0.05415 seconds 1 example, 1 failure Failed examples: rspec ./spec/classes/mongodb_spec.rb:14 # mongodb On an Ubuntu install, admin and single user rake aborted! /usr/bin/ruby1.8 -S rspec spec/classes/mongodb_spec.rb --color failed Tasks: TOP => spec_standalone (See full trace by running task with --trace) Module spec testing is relatively new, as is hiera. So far I have been unable to find any suitable solutions. (the back and forth on puppet-dev was interesting, but not helpful). What changes do I need to make to get this to work? Installing puppet from a gem and hacking on rubylib isn't a viable solution due to corporate policy. I am using Ubuntu 12.04 LTS + Puppet 2.7.17 + hiera 0.3.0.

  • Epson Artisan 800 on Ubuntu/Linux

    - by Tim Lytle
    Update for Ubuntu 10.04: Printing should work 'out-of-box', scanning still needs the newer sane backend. Looking for a known good way to setup an Epson Artisan 800 on Ubuntu specifically or any linux box in general. It is a printer/scanner with ethernet/wifi/usb. I'd like to use it as a network printer/scanner being able to do both from my Windows and Ubuntu machines; however, if it needs to be physically connected to a computer (preferably the Ubuntu machine) that is doable (again, then sharing print/scan functions to the network). Basically, I'm looking for someone who has used this printer/scanner (or similar) in a multi-platform environment to share how the set it up and how well it worked. Updated: A little more information, like most printers (I expect) the documentation for the printer basically says, "don't use plug-n-play, run our setup CD from your Windows/Mac system", to do anything (set it up for network use even). I guess that's to make it easy for anyone else to setup, but when you're looking to use it with an unsupported (by Epson's documentation) OS, you're just stuck on your own. What I was hoping for was someone who could say, "Forget the bundled software, do [this] to set it up on wifi manually, install [this] to connect to the scanner from [os], printing works with [this] driver - at least that's how I set it up." I'll will (and have so far) use the information here, and post my own setup when I'm done, if there's no one else out there with that experience.

  • administrator user unable to login, suspicious user accounts "sky$", "admin$"

    - by mks
    I have a Windows 2008 R2 Standard (64 bit) running in a virtual machine. Suddenly from yesterday onwards I am not able to login as administrator. Nobody changed the password. Both in the console as well as using remote desktop I am unable to login. Whenever I login as Administrator I am getting this error: "The user name or password is incorrect" Nothing has changed in the machine and I have logged in the past successfully both through console and via remote desktop several time on the same machine. One strange behaviour I noticed is, I am seeing some additional user accounts if I try to login as other user. The suspicious user account are: sky$ admin$ SUPPORT_388945a0 Is it created by some malware/virus? Or is it some windows hidden account? Microsoft site says that SUPPORT_388945a0 is: The Support_388945a0 account enables Help and Support Service interoperability with signed scripts. This account is primarily used to control access to signed scripts that are accessible from within Help and Support Services. Administrators can use this account to delegate the ability for an ordinary user, who does not have administrative access over a computer, to run signed scripts from links embedded within Help and Support Services. These scripts can be programmed to use the Support_388945a0 account credentials instead of the user’s credentials to perform specific administrative operations on the local computer that otherwise would not be supported by the ordinary user’s account. When the delegated user clicks on a link in Help and Support Services, the script executes under the security context of the Support_388945a0 account. This account has limited access to the computer and is disabled by default. However I am not sure from where this "admin$" and "sky$" came. Anyone has similar experience?

  • SQL 2008 SP1 crashing almost daily

    - by matijake
    Hey, almost every day our new DB crashes. It is virtual server residing on same hardware as 5 other servers, two of them beeing identical MS SQL2008sp1 and two Oracle 11g's so I can pretty much rule out hardware issues. Server has dedicated local LUN, 4vCPU and 8GB memory with 2GB windows swap file. It runs 4 instances. Primary instance is limited to 5GB memory and paralelism set to 4 running on MS SQL 2008 SP1 @ Windows Server 2008 Enterprise R2 x64. Only that primary instance is crashing. After it crashes nothing can connect to it, it's even impossible to shut it down through service manager. What I found in logs is: ***Stack Dump being sent to C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\LOG\SQLDump0081.txt SqlDumpExceptionHandler: Process 4788 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server i s terminating this process.     Whole log can be seen at: http://kabl.org/files/SQLDump0081.txt second crash log made second later at: http://kabl.org/files/SQLDump0082.txt I have analyzed mini crashdump with Microsoft tools, but no promising results. If it can help, here it is: http://kabl.org/files/SQLDump0081.mdmp Any ideas are greatly welcome, since it is becoming quite a pain in the ass to restart server almost every day :) Regrads, -Matija

  • Do entries in local 'hosts' files override both forward and reverse name lookups?

    - by Murali Suriar
    If I have the following entries in a hosts file: 192.168.100.1 bugs 192.168.100.2 daffy.example.com 192.168.100.3 elmer.example.com. Will IP-name resolution attempts by local utilies (I assume using 'gethostbyaddr' or the Windows equivalent) honour these entries? Is this behaviour configurable? How does it vary between operating systems? Does it matter whether the 'hosts' file entries are fully qualified or not? EDIT: In response to Russell, my test Linux system is running RHEL 4. My /etc/nsswitch.conf contains the following 'hosts' line: hosts: files dns nis If I ping any of my hosts by name (e.g. bugs, daffy), the forward resolution works correctly. If I traceroute any of them by IP address, the reverse lookup functions as expected. However, if I ping them by IP, ping doesn't appear to resolve their host names. My understanding was that Linux ping would always attempt to resolve IPs to names unless instructed otherwise. Why would traceroute be able to handle reverse lookups in hosts files, but ping not?

  • computer build for extreme tabbed browsing

    - by David Berger
    I'm interested in building or buying a task-specific computer for my brother. His requirements are ridiculously simple: the machine has to be able to wait in hundreds of web-based virtual waiting rooms at once and not crash. To be competitive, he needs to be able to enter the waiting rooms an dauto-refresh them faster. My question is, what priority do I give the different specs? My initial surmise is this: Connection speed (nothing to do with my build, but I kind of think this will be more beneficial than anything I build for him) Memory size -- I don't usually see firefox taking up more than a gig, even when heavily tabbed, but I think one gig for the operating system and two gigs for the browser are necessary. Processor speed -- I think the processor will affect performance, but even something out of date will do what he needs Memory speed/RAM bus -- I doubt this will matter much, but it seems just on this side of irrelevant. Everything else is a non-issue for him. Does this seem to stack up correctly? Also, since he's looking to stay on the cheaper side, and I might end up recommending a refurb to him, is there anything particularly egregious that Vista would do if it came pre-installed? If I build it myself, I'll give him linux, but if I have it shipped to him, I'm not sure I could walk him through the install process for linux, but I probably could walk him through the process to upgrade to Windows 7, if it were somehow worth it.

  • Setting up Windows network on Xen

    - by samyboy
    I'm trying to install a Windows XP server in a Xen environment. The OS is booting fine. Unfortunately I can't figure out how to set up the network settings.

  • Intel NIC X540-T1 non-functional in Ubuntu Server 12.04

    - by Jeff Carr
    I have installed three Intel X540-T1's in servers running Ubuntu Server 12.04, but all are non-functional, no link lights, no packets sent or received, and no connection on ip4 or ip6 whether set up as dhcp or static. Also, dmesg doesn't detect cable connection or disconnection. I updated the default ixgbe driver to Intel's latest version (3.11.33) with no change. The ethernet controller is being reported as X540-AT2 (which might be a problem that I can't figure out how to fix), but the subsystem is X540-T1 so I believe that might be intended. Does anyone have any experience with this that could assist? ifconfig eth2 eth2 Link encap:Ethernet HWaddr a0:36:9f:14:5f:ea inet addr:192.168.101.1 Bcast:192.168.101.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1<br> RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) ethtool -i eth2 driver: ixgbe version: 3.11.33 firmware-version: 0x8000037c bus-info: 0000:08:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes lspci -vvnns 08:00.0 08:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller 10 Gigabit X540-AT2 [8086:1528] (rev 01) Subsystem: Intel Corporation Ethernet Converged Network Adapter X540-T1 [8086:0002] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr+ Stepping- SERR+ FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 16 Region 0: Memory at e8000000 (64-bit, prefetchable) [size=2M] Region 4: Memory at e8200000 (64-bit, prefetchable) [size=16K] [virtual] Expansion ROM at e8280000 [disabled] [size=512K] Capabilities: <access denied> Kernel driver in use: ixgbe Kernel modules: ixgbe

  • VirtualBox communication from Linux to/from Windows 7

    - by J. Otto Tennant
    VirtualBox is running in Windows 7 as the host. VirtualBox has the two modifications (one is called Guest Additions; don't remember the other). The Virtual machine has "bridged" networking selected. I have SAMBA set up (now, the problem may be here; it has been three or four years since I last did this) on the Linux guest machine. Neither guest nor host sees the other. From the Windows 7 command prompt, the IP address of the Linux guest pings. The IP address of another computer (a separate Windows 7 on the wireless network) pings from the Linux guest. (I have no idea what IP address the Windows 7 host itself has. The output of "netstat" does not seem to be useful.) So, it seem to me that something should be working. The only workgroup on the LAN is inventively named WORKGROUP. SMB4K should be seeing something. There must be a simple setup step that I am missing. (FWIW, there are two processes running smbd, and no process is running nmbd. YaST says that nmbd is set to run. I am not sure what this means.)

  • Libvirt / QEmu Machine Fails and Refuses Restart Because of Memory Allocation Errors

    - by Elmar Weber
    I'm having a problem with libvirt. On a system restart all virtual machines (VMs) are started without a problem and keep running. Then at some point in time a set of machines shuts down according to their log. When I try to restart the machine, I'm getting an error that the memory allocation failed, although more than enough memory is free. server ~ # free total used free shared buffers cached Mem: 16176648 16025476 151172 0 285432 950300 -/+ buffers/cache: 14789744 1386904 Swap: 0 0 0 server ~ # virsh start zimbra error: Failed to start domain zimbra error: Unable to read from monitor: Connection reset by peer server ~ # tail -n 4 /var/log/libvirt/qemu/zimbra.log LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 3072 -smp 2,sockets=2,cores=1,threads=1 -name zimbra -uuid d05ddb7a-83c4-a77b-d8bc-a322648520cf -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/zimbra.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -drive file=/var/lib/libvirt/images/zimbra.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,fd=19,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:21:a9:ad,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 192.168.1.2:25 -k de -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 char device redirected to /dev/pts/2 Failed to allocate 3221225472 B: Cannot allocate memory 2012-07-06 08:42:56.076+0000: shutting down server ~ # uname -a Linux server 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The system is a Ubuntu 12.04 server. The problem seems to occurs since the last restart, which was due to a number of package upgrades and a kernel upgrade. I tried booting with the previous kernel, the problem persists. I was not able to pinpoint an exact event when the machines fail, they do it at nearly the same time. The last time a duplicity job was running, this was not always the case however. Any suggestions on how to debug this? Best regards, elm

  • Tcpreplaying using VMware

    - by Methos
    This is more like a testbed setup question. I want to use VMware to debug some networking code in the linux kernel in the VM. My VM has two network interfaces. What I want to do is replay the capture file in the host and receive the packets in the VM. My problem is I do not see replayed packets in the VM. I am running VMware and tcpreplay on the host as sudo. Hence I think there should not be any problem access devices files. I am running VMware workstation 7.0 a. I first began with Custom networking as that provides option of creating your own virtual network name. I wrote /dev/vmnet3 and /dev/vmnet4 for the two interfaces respectively. However, after booting the guest, I did not see any of these interfaces or devices files (in /dev) created on the host. b. Then I tried 'Host Only', but that does not show what bridge/device file is associated with the interface. c. Finally I tried bridged networking mode. I see vmnet1, vmnet8 and vboxnet0 on the host. I have tcpreplayed the capture file on each of these interfaces, for all the above three cases. I tried to capture packets in the VM using "tcpdump -i any". However, I do not see any packets. Any ideas/pointers?

  • Need help with custom init script

    - by churnd
    I'm trying to set up an init script for a process on redhat linux: #!/bin/sh # # Startup script for Conquest # # chkconfig: 345 85 15 - start or stop process definition within the boot process # description: Conquest DICOM Server # processname: conquest # pidfile: /var/run/conquest.pid # Source function library. This creates the operating environment for the process to be started . /etc/rc.d/init.d/functions CONQ_DIR=/usr/local/conquest case "$1" in start) echo -n "Starting Conquest DICOM server: " cd $CONQ_DIR && daemon --user mruser ./dgate -v - Starts only one process of a given name. echo touch /var/lock/subsys/conquest ;; stop) echo -n "Shutting down Conquest DICOM server: " killproc conquest echo rm -f /var/lock/subsys/conquest rm -f /var/run/conquest.pid - Only if process generates this file ;; status) status conquest ;; restart) $0 stop $0 start ;; reload) echo -n "Reloading process-name: " killproc conquest -HUP echo ;; *) echo "Usage: $0 {start|stop|restart|reload|status}" exit 1 esac exit 0 However, the cd $CONQ_DIR is getting ignored, because the script errors out: # ./conquest start Starting Conquest DICOM server: -bash: ./dgate: No such file or directory [FAILED] For some reason, I have to run dgate as ./dgate. I cannot specify the full path /usr/local/conquest/dgate The software came with an init script for a Debian system, so the script uses start-stop-daemon, with the option --chdir to where dgate is, but I haven't found a way to do this with the Redhat daemon function.

  • Running Debian as guest operating system on a Hyper-V VM

    - by kce
    Hello. Layer-9 considerations are prompting a migration from Citrix XenServer to Hyper-V as our shop's virtualization platform of choice. This will require me to migrate our existing virtual machines from XenServer to Hyper-V. A hand full of these VMs are running Debian. Unfortunately, Debian does not seem to be on the list of approved/supported guest operating systems. In fact it seems that running Debian as a guest operating system of is rather difficult, although apparently not impossible. I have two interrelated questions: Does anyone have any experience running a Debian guest on Hyper-V? Is it one of those things where it just will not work at all or is more along the lines of "it will probably work fine, but we won't support it". Any experience here, positive or negative, would be helpful. How much of a bad idea is it to deviate from Hyper-V's list of supported guest operating systems? Again, is it either basically asking for Bad Things (TM) to happen or is just another instance of "it will probably work fine, but we won't support it"? Or is it somewhere in the middle? Thank you.

  • Windows Server 2008 R2 - Cannot Change DNS Domain Context on Some Machines

    - by Richie086
    So I have a small Windows Server 2008 R2 network consisting of a domain controller, a file server, sql server, etc. All machines are joined to a windows domain (CPUSHIELD.COM) and show up in Active Directory Users and Computers under the Computers OU. Each computer has a DNS record as well that was populated when I joined each computer to the domain. However, when I go to my SQL server VM (which is joined to CPUSHIELD.COM) and try to add domain users or groups to the local users or groups on my file server (which is a physical machine) or my sql server (which is a virtual machine), for some reason I cannot change the context to the CPUSHIELD.COM domain.. For example: Here is the really strange thing, I have two other servers on my network that do show CPUSHIELD.COM in the From This Location field (as I would expect with any machine joined to a domain) and I am able to search the local machine and/or domain for users/groups to add. I have done hundreds of Windows Server 2008 installs and this is the first time I have run into this issue. Any ideas? Let me know if you need more info

  • Mac OS X Lion Apache Server not Found

    - by Burak Erdem
    After upgrading to Lion 10.7.2 today, Apache virtual hosts are not working anymore. When I go to http://XYZ.localhost, it say "server not found". I am using Apache on my Mac OS X Lion and until today, it was working fine. I can access http://localhost but I can't access http://XYZ.localhost My /etc/hosts file is like below; 127.0.0.1 XYZ.localhost My /etc/apache2/extra/httpd-vhosts.conf file is like below; <VirtualHost *:80> ServerName XYZ.localhost DocumentRoot /Library/WebServer/Documents/XYZ <Directory /Library/WebServer/Documents/XYZ> DirectoryIndex index.php AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> I think I once had this problem too, after another OS X update, but I can't remember how I solved it. Is it a user permission issue? Or is there something wrong with Apache or any other setting? EDIT: It seems like my /etc/hosts file is not working correctly. Even if I add something like 127.0.0.1 apple.com it still goes to the real apple.com. Maybe this might help to solve the problem.
