  • Running Untangle on Virtualbox as a Transparent Bridge

    - by user38697
    I am setting up Untangle in a Sun VirtualBox VM. I plan on using this machine as a transparent bridge to filter and monitor traffic on my network. I'm not sure how to configure the network adapters for the virtual machine under the Virtualbox's "Devices" menu so that it will function as a transparent bridge. I guess what I'm asking is, should both adapter 1 & 2 be set as Bridged adapters or what? Any help is greatly appreciated.

  • OpenSSL Handshake Failure (14094410) - Erroneous Client Certificate Check from Mobile Phone

    - by Clayton Sims
    I'm running a proxy server through Apache with modssl, which we're using to proxy POSTs from mobile devices to another internal server. This works successfully for most clients, but requests from a specific phone model (Nokia 2690) are showing a bizarre handshake failure. It looks as though OpenSSL is either requesting (or attempting to read an unsolicited) client certificate from the phone (which is especially bizarre because j2me's kssl implementation doesn't support client certs). I've disabled client certificates with the SSLVerifyClient none directive in both the virtual host conf and the modssl conf. The trace from error.log on debug level is (details redacted): [client 41.220.207.10] Connection to child 0 established (server www.myserver.org:443) [info] Seeding PRNG with 656 bytes of entropy [debug] ssl_engine_kernel.c(1866): OpenSSL: Handshake: start [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: before/accept initialization [debug] ssl_engine_io.c(1882): OpenSSL: read 11/11 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d0] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1882): OpenSSL: read 49/49 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90db] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 read client hello A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write server hello A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write certificate A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write server done A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 flush data [debug] ssl_engine_io.c(1882): OpenSSL: read 5/5 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d0] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1882): OpenSSL: read 2/2 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d5] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_kernel.c(1879): OpenSSL: Read: SSLv3 read client certificate A [debug] ssl_engine_kernel.c(1898): OpenSSL: Exit: failed in SSLv3 read client certificate A [client 41.220.207.10] SSL library error 1 in handshake (server www.myserver.org:443) [info] SSL Library Error: 336151568 error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure [client 41.220.207.10] Connection closed to child 0 with abortive shutdown (server www.myserver.org:443) I've tried enabling all ciphers and all protocols temporarily with modssl, neither of which seemed to be the issue. The phone should be using RSA_RC4_128_MD5 and SSLv3, all of which are available. Am I missing something more fundamental about what's failing here? It seemed like the certificate request might have been part of a renegotiation failure. I tried enabling SSLInsecureRenegotiation On on the virtual host, in case it was an issue of the phone's SSL not supporting the new protocol, but to no avail. Currently running: Apache/2.2.16 (Ubuntu) mod_ssl/2.2.16 OpenSSL/0.9.8o Apache proxy_html/3.0.1

  • Login box not shown on Ubuntu

    - by Alexandre
    Hi, I've installed Ubuntu 10.04 (64bit) as a guest OS in VirtualBox, using Windows7 Professional (64bit) as host. After Ubuntu install, I did installed Xfce4 (sudo apt-get install xfce4). Logged in using a Xfce session, and when I logged out, I couldn't see the login box anymore, only the regular gnome background from login screen. Then I restarted the virtual machine, and now I'm not able to see the login box anymore, only the gnome background. Does someone knows how to solve this? Thanks in advance

  • Windows 7 Enterprise MAK needs Reactivation?

    - by chris
    I have a VMware image that contains our "standard workstation" where I do a lot of testing. I used a Windows 7 Enterprise MAK key (from MSDN) for activation because the doc said that MAK keys don't have to be reactivated when the hardware changes. Activation was done with slmgr.vbs /ipk LICENSE-KEY slmgr.vbs /ato Now after some testing where the virtual hw was changed it says it "needs to activate because the hw has changed". What did I do wrong?

  • Including hostname in apache logwatch reports

  • Windows: what is the difference between DEP always on and DEP opt-out with no exceptions?

    - by Peter Mortensen
    What is the difference between DEP always on ("/NoExecute=AlwaysOn" in boot.ini) and DEP opt-out ( "/NoExecute=OptOut" in boot.ini) with no exceptions? "no exceptions" = empty list of programs for which DEP does not apply. DEP = Data Execution Prevention (hardware). One would expect it to work the same way, but it makes a difference for some applications. E.g. for all versions of UltraEdit 14 (14.2). It crashes at startup for DEP always on, at least on Microsoft Windows XP Professional Edition x64 edition. (2010-03-11: this problem has been fixed with UltraEdit 15.2 and later.) Update 1: I think this difference is caused by the backdoors that Microsoft has put into hardware DEP for OptOut, according to Fabrice Roux (see below). In the case of IrfanView, for which Steve Gibson observed the same difference as I did for UltraEdit (see below), the difference is caused by a non-DEP aware EXE packer (ASPack) that Microsoft coded a backdoor for. Is there a difference between Windows XP, Windows Vista and Windows 7 ? Is there a difference between 32 bit and 64 bit versions of Windows ? Sources: From [http://blog.fabriceroux.com/index.php/2007/02/26/hardware_dep_has_a_backdoor?blog=1], "Hardware DEP has a backdoor" by Fabrice Roux. 2007-02-26. "IrfanView was not using any trick to evade DEP ... Microsoft just coded a backdoor used only in OPTOUT. Bascially Microsoft checks the executable header for a section matching one of the 3 strings. If one these strings is found, DEP will be turned OFF for this application by windows. ... 'aspack', 'pcle', 'sforce'" From [http://www.grc.com/sn/sn-078.htm], by Steve Gibson. "I can’t find any documentation on Microsoft’s site anywhere, because we’re seeing a difference between always-on and opt-out. That is, you would imagine that always-on mode would be the same as opting out if you weren’t having any opt-out programs. It turns out it’s not the case. For example ... the IrfanView file viewer ... runs fine in opt-out mode, even if it has not been opted out. But it won’t launch, Windows blocks it from launching ... in always-on mode." From [http://www.grc.com/sn/sn-083.htm], by Steve Gibson. "... IrfanView ... won’t run with DEP turned on. It’s because it uses an EXE packer, an executable compression program called ASPack. And it makes sense that it wouldn’t because naturally an executable compressor has got to decompress the executable, so it allocates a bunch of data memory into which it decompresses the compressed executable, and then it runs it. Well, it’s running a data allocation, which is exactly what DEP is designed to stop. On the other hand, UPX, which is actually the leading and most popular EXE compressor, it’s DEP- compatible because those guys realized, hey, when we allocate this memory, we should mark the pages as executable."

  • Debian (wheezy) force cache to RAM

    - by Marek Javurek
    I have Linux server running about 6 game servers. I have 3 GB total of RAM but I use only about 500 MB. Is there a way to cache one of my game servers (all the files - even not actually used maps etc. - about 1,5 GB) to RAM? The reason I want to do this is because my Linux server is virtual and the hard drives ar very slow, so there is really big IO wait time. IO: http://i.stack.imgur.com/7HLhB.png

  • How to setup Hadoop cluster so that it accepts mapreduce jobs from remote computers?

    - by drasto
    There is a computer I use for Hadoop map/reduce testing. This computer runs 4 Linux virtual machines (using Oracle virtual box). Each of them has Cloudera with Hadoop (distribution c3u4) installed and serves as a node of Hadoop cluster. One of those 4 nodes is master node running namenode and jobtracker, others are slave nodes. Normally I use this cluster from local network for testing. However when I try to access it from another network I cannot send any jobs to it. The computer running Hadoop cluster has public IP and can be reached over internet for another services. For example I am able to get HDFS (namenode) administration site and map/reduce (jobtracker) administration site (on ports 50070 and 50030 respectively) from remote network. Also it is possible to use Hue. Ports 8020 and 8021 are both allowed. What is blocking my map/reduce job submits from reaching the cluster? Is there some setting that I must change first in order to be able to submit map/reduce jobs remotely? Here is my mapred-site.xml file: <configuration> <property> <name>mapred.job.tracker</name> <value>master:8021</value> </property> <!-- Enable Hue plugins --> <property> <name>mapred.jobtracker.plugins</name> <value>org.apache.hadoop.thriftfs.ThriftJobTrackerPlugin</value> <description>Comma-separated list of jobtracker plug-ins to be activated. </description> </property> <property> <name>jobtracker.thrift.address</name> <value>0.0.0.0:9290</value> </property> </configuration> And this is in /etc/hosts file: 192.168.1.15 master 192.168.1.14 slave1 192.168.1.13 slave2 192.168.1.9 slave3

  • Hide usernames shown on Windows Server 2008 Remote Desktop login screen

    - by user38553
    When I remote desktop to my Windows Server 2008 (a hosted virtual server) I see a login screen showing an icon for each user in the system. I can click on a user then enter a password and login. This is a terrible security oversight in my opinion as it gives anyone that might want to compromise my server a full list of valid usernames. Is there a way to revert to the old style of login screen requiring both username and password? Thanks

  • What’s the Minimum System Spec Recommended For Developer Laptop

    - by DaveDev
    I'll be regularly running Visual Studio 2010 Professional, SQLServer Express, Office and at least 1 virtual environment running a Linux Distro. I want the machine to be snappy and responsive even when doing a reasonable amount of Development work. I want to spend what it takes for this, but I don't want to go overboard spending more than I need to. I won't be playing many games or graphics processing so i won't need a monster of a machine. Any recommendations?

  • Internet Forwarding With Qemu?

    - by ConfusedGuy
    I'm using kvm and qemu to run a windows virtual machine, but I'm trying to get internet on that machine. I've been reading about all this bridging and stuff that is done to do that, but I was wondering if there was a simpler way, to just forward my internet connection (since I'm connected on the host machine) through qemu to the guest operating system. Is this possible? Thanks

  • Using Cisco VPN in Windows 7 XP Mode?

    - by Shane
    I previously asked a question about whether it was possible to use Cisco VPN client on Windows 7 64-bit (see below). Now that I have it set up, it doesn't work when I try to connect off the local network. I realize that there must be some networking/routing that I need to do since it's running on a virtual machine. How does one go about using the Cisco VPN client from XP mode in Windows 7? Related: Cisco VPN Client on Windows 7 64-bit?

  • Trac problem: AttributeError: Cannot find an implementation of the "IRequestHandler" interface named "WikiModule"

    - by Janosch
    This problem already has been described mutliple times in different mailing lists, but no solution has yet been published. My original setup is as follows (but in the mean time i have a simpler one on Windows 7): Ubuntu server with apache 2.2 and python 2.7 virutal python environment created with virtualenv installed babel, genshi and trac in this order using pip in the virtual environment Trac seems to run fine with tracd, but when visiting it through apache, i get the following error in an official trac error page: AttributeError: Cannot find an implementation of the "IRequestHandler" interface named "WikiModule" The stacktrace looks like this: Traceback (most recent call last): File "/srv/trac/python-environment/lib/python2.5/site-packages/Trac-0.13dev_r10668-py2.5.egg/trac/web/main.py",line 473, in _dispatch_request dispatcher.dispatch(req) File "/srv/trac/python-environment/lib/python2.5/site-packages/Trac-0.13dev_r10668-py2.5.egg/trac/web/main.py", line 154, in dispatch chosen_handler = self.default_handler File "/srv/trac/python-environment/lib/python2.5/site-packages/Trac-0.13dev_r10668-py2.5.egg/trac/config.py", line 691, in __get__ self.section, self.name)) AttributeError: Cannot find an implementation of the "IRequestHandler" interface named "WikiModule". Please update the option trac.default_handler in trac.ini. I already tried a lot to get down to the root of the problem, for me it looks as if all nativ trac components refuse to load. When one explicitely imports these components in the wsgi handler, some of them start to work somehow. Since i suspected the virtual environment, i dropped it, and manually copied all dependencies (babel, genshi, trac, ..) to one directory, and added this directory to system.path in the wsgi handler. I get exactly the same error. Since this setup is now independend from the environment, one can easily try it out on any other machine (windows or linux) running apache 2 and python 2.7. On my Windwos 7 machine, i got exactly the same problem. I zipped together the whole bundle, one can download it from http://www.xterity.de/tmp/trac-installation.zip . In the apache configuration (Windows 7 machine) i use the following settings: Alias /trac/chrome/common "D:/workspace/trac-installation/trac-resources/common" Alias /trac/chrome/site "D:/workspace/trac-installation/trac-resources/site" WSGIScriptAlias /trac "D:/workspace/trac-installation/apache/handler.wsgi" <Directory "D:/workspace/trac-installation/trac-resources"> Order allow,deny Allow from all </Directory> <Directory "D:/workspace/trac-installation"> Order allow,deny Allow from all </Directory> <Location "/trac"> Order allow,deny Allow from all </Location> And my handler.wsgi looks like this: import os import sys sys.path.append('D:/workspace/trac-installation/dependencies/') os.environ['TRAC_ENV'] = 'D:/workspace/trac-installation/trac-environments/Esp004' os.environ['PYTHON_EGG_CACHE'] = 'D:/workspace/trac-installation/eggs' import trac.web.main application = trac.web.main.dispatch_request Has anybody got an idea what could be the problem, or how to find out where it comes from?

  • Cannot run a VM with more than three network interfaces with KVM

    - by Bostonvaulter
    I'm running KVM on top of Ubuntu 10.10 Server I can create VM's (Virtual Machine) and network interfaces fine but I cannot seem to add more than three network interfaces. As soon as I have a VM with four network interfaces it gets stuck on startup at the starting SeaBIOS page with this message: Starting SeaBIOS (version pre-0.6.1-20100702_143500-palmer) So far I've verified this with two VM's, a Ubuntu 10.10 desktop and a Vyatta router. The specific network hardware I assign to the VM's doesn't seem to matter. I'm trying to have one bridged interface and three private networks using Vyatta to route between them. Does anyone know why I can't run a VM with more than three network interfaces? Edit: Additionally the KVM thread responsible for the specific VM hangs using ~100% CPU (i.e. one core). Here's the command for the process that is hanging: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name vyatta -uuid 6dff7c94-6810-423e-5fea-fec10da0e9b7 -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/vyatta.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=utc -boot c -drive file=/home/rams/virtual-machines/vyatta.img,if=none,id=drive-ide0-0-0,boot=on,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -device rtl8139,vlan=0,id=net0,mac=00:54:00:be:cc:4b,bus=pci.0,addr=0x3 -net tap,fd=97,vlan=0,name=hostnet0 -device rtl8139,vlan=1,id=net1,mac=52:54:00:da:59:ed,bus=pci.0,addr=0x5 -net tap,fd=98,vlan=1,name=hostnet1 -device rtl8139,vlan=2,id=net2,mac=52:54:00:ce:22:b6,bus=pci.0,addr=0x6 -net tap,fd=99,vlan=2,name=hostnet2 -device rtl8139,vlan=3,id=net3,mac=52:54:00:1e:bc:46,bus=pci.0,addr=0x7 -net tap,fd=101,vlan=3,name=hostnet3 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -vnc 127.0.0.1:0 -k en-us -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 Edit: I've also found an error in dmesg that might be related (it also shows up when running virtd in verbose mode): 14:47:24.399: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status '1', qemu probably failed I've also tried disabling app armor but that doesn't seem to make a difference.
