  • Using OpenVPN, yet netflix.com blocks access

    - by user837848
    I have set up an OpenVPN server on a VPS in the USA and configured it to route all clients traffic through it. Everything seems to work fine regarding the VPN connection in gerneral. All ip lookup sites show me the us server's ip address and even hulu.com works(it won't work if you are not in the usa). But for some reason netflix.com says "Sorry, Netflix is not available in your country yet.". So I thought that netflix probably uses some more sophisticated ways to determine your location beyond just your ip address. But I could not find a way to get it to work until I dropped the idea of using a VPN and instead connected to the server via a simple socks tunnel with ssh by running: ssh -D 9999 user@serverip All I had to do was changing the key network.proxy.socks_remote_dns in Firefox from false to true to prevent DNS leaks and setting up the socks proxy. Then I could finally watch netflix.com. As a result I concluded that there is nothing in the browser(or something like system timezone) that tells netflix the location, so it has to have something to do with the OpenVPN config. After that I used tcpdump to log all the traffic on the server's network interface venet0 (OpenVZ VPS), visited netflix.com on the client while first connected to the VPN and then connected via socks tunnel and afterwards compared both outputs. The only thing that caught my eye was that while using the socks tunnel the server mainly used ipv6 to connect to netflix whereas it only used ipv4 when the client was connected to the OpenVPN server. But I don't get how that could make such a difference. So what am I missing? Is there a way to configure OpenVPN to also use ipv6 to connect to a website although there is only an ipv4 connection between the VPS and the client? Here is the server.conf of the OpenVPN server (OpenVZ VPS) local serverip port 443 proto tcp dev tun ca ./easy-rsa2/keys/ca.crt cert ./easy-rsa2/keys/vps1.crt key ./easy-rsa2/keys/vps1.key # This file should be kept secret dh ./easy-rsa2/keys/dh1024.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4" client-to-client keepalive 10 120 tls-auth ta.key 0 # This file is secret cipher AES-256-CBC comp-lzo max-clients 4 user nobody group nogroup persist-key persist-tun status openvpn-status.log log-append openvpn.log verb 3 iptables forwarding iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o venet0 -j SNAT --to-source serverip (enabled ipv4 forwarding) I have tried everything always on a Win7 and a Debian client with only ipv4 connections and always made sure that they use the correct DNS server (tested with ipleak.net and tcpdump / wireshark). client.conf: client dev tun proto tcp remote serverip 443 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key ns-cert-type server tls-auth ta.key 1 cipher AES-256-CBC comb-lzo verb 3

  • CentOS 5.7 keeps rebooting after fresh installation

    - by Wagner Maestrelli
    I have just installed CentOS 5.7 x86_64 on a new computer. The installation went on without any issues. But, after it finnished, the machine started to show an awkward behaviour: it restarts every time it tries to boot. It happens after all the services have been started. The screen just goes black and it shows an error message from the monitor: Input not supported. And then it reboots. I took a look at the logs, but I couldn't manage to find anything. Any help? Update Before doing the hardware diagnosis, as pointed out, I decided to make some tests. First, I changed the runlevel to 3, adding the 3 parameter at the end of the kernel command. Then, after logging in in text mode, I checked the xorg.conf file out for some problems regarding the screen resolution. There was nothing unexpected set. Well, if there had to be a problem with it, I couldn't start the X server at the command line, right? So, I typed startx and Gnome started! So, probably, it's not an issue with the screen resolution, I suppose. Then I selected the Log Out root... Gnome menu option and something odd happened: the screen went black, the Input not supported monitor error message was displayed and the system rebooted. Yes, the same problem I was having while trying to boot! After that, I decided to try yet another test: I removed the rhgb quiet parameters from the kernel command to see if some error would show up. Well, to my surprise, the boot went on without problems! The Gnome login screen showed up, I logged in and the session started. But then I selected the Shut Down... menu option and guess what? Same problem: black screen, same monitor error and the system rebooted. Yes, it rebooted, it did not shut down. I repeated both of the tests and the behaviours were the same. I really don't know what's going on. It seems to be an issue regarding the changing of the screen mode or something like that. Any ideas? Could this be a hardware problem? Or does it seem to be something regarding the system configuration?

  • Linux (Ubuntu 12.04) two gateways one nic

    - by David
    I have Ubuntu 12.04 Server edition Two gateways, both on 192.168.0. network, let's make them 192.168.0.1 and 192.168.0.2 I've read you should be able to add second gateway into /etc/network/interfaces, that it will build out all the routing automatically, but I get "duplicate option" error. So if I have one default gateway, let's say 0.1, and a connection comes through from the 0.2 gateway, my understanding is that it still tries to respond through 0.1 gateway. Can we change this behavior?

  • Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP

    - by Harley
    This is something I setup recently and was quite a big pain. My environment was getting squid to authenticate a Windows 7 client against a Windows 2008 Server invisibly. NTLM is not really an option, as using it requires a registry change on each client. MS have been recommending Kerberos since Windows 2000, so it's finally time to get with the program. Many, many thanks to Markus Moeller of the Squid mailing lists for helping to get this working.

  • Windows XP procedurally drop packets

    - by Michael J Mulligan
    We have a need in our office network to procedurally drop incoming packets on an XP machine acting as a server. By procedurally we mean to drop a percentage of packets incoming on the XP machine from a specific IP. Asked here because these seem like server related questions. And none of us have really any idea how to execute this. Another option is to introduce intermittent latency for an incoming IP. Thank you for your help.

  • Can't connect to samba

    - by Rick
    Windows 7, connecting to Samba shares I have a follow up question from the link above. I am running Samba 3.0.23d on FreeBSD is release 7.1 I changed the policies as described above but still cannot connect to the samba server with the windows 7 or a server 2008. I feel it is a problem with recognizing the new machines on the network. the windows machines can see the samba server, but cannot connect to it or view any of the files. After changing the security policies the samba server asked for network id and password but would not allow the machine to connect, said they were unknown username or bad password. Here is my current config file. there is no sign of encryption anywhere, should I just add the line? not sure what that would do elsewhere.

  • Adding a Microsoft Exchange 2010 account to my Windows Phone 7.5 mobile (Nokia Lumia 800) without trusted certificate

    - by MAXE
    I have problems in creating an account on my Nokia Lumia 800 (OS version: 7.10.8773.98, of course with Windows Phone 7.1 mounted with all updates) to one of my company's Microsoft Exchange 2010 server, because it cannot provide a trusted certificate...but only when contacting it from outside my network (like https ://mail.(CompanyName).com). Accessing the server from inside my network (pointing directly to the machine name or internal IP address: https ://(MachineName) or https ://10.0.1.200) gives me NO PROBLEM AT ALL! Setting correctly (I guess) all the parameters for the account (accessing from outside my network), the connection (after correctly set my credentials as asked) will not be established. It gives the next error (translated from my language manually): Error of <CompanyName> There is a problem with the certificate of (Server Address). Please contact support or the provider. Last try: X minutes ago Error code: 80072F06 I've tried all possible configurations and parameters (including the check The server requires an encrypted (SSL) connection, of course), but no way. EDITED: As suggested by Oliver Salzburg, I also tried this way without any results. I tried so: I went to my OWA (Outlook Web Access) that gives me the same problem (problems the certificate, it's not trusted) After accepting to continue, I clicked on the Error in Certificate button of the Internet Explorer 9 address bar - Show Certificates - page Details, show: - Copy to file... button - in the exporting wizard: Next - Binary encoding DER X.509 (.cer) (but there was also Base binary 64 X.509 (.cer), no way) - Next - saved to a new file From my Google Mail Account, I sent a mail to myself the certificate as attachment I read the mail from my WP7 phone, saved the attachment and then ran it: answering Yes to Do you wany to install the certificate? of course... Closed any active program and rebooted the phone Re-tried in synchronizing my account....:(...SAME PROBLEM! EDITED 2: Thanks again to Oliver Salzburg, I tried the next solution: I went to the site https://www.testexchangeconnectivity.com/ I selected Exchange ActiveSync option, as suggested I setted all my parameters, as I made for my phone I also setted the option Ignore SSL attendibility (and in another test I didn't) I performed my test This is the complete log (I removed my parameters): Seems the same problem (machine name in the certificate is different from the external Exchange website domain name?)! It is possible to get rid of this annoying (I know by myself who is this server!) problem? Thank you very much.

  • Can the Intel C600-series SAS controller RAID SATA drives?

    - by CyberShadow
    (Sorry if this is off-topic - technically this is a home workstation setting, but is regarding mostly-server technology.) I have a GA-X79S-UP5-WIFI motherboard and four ST3000DM001 drives, and the IRST manager isn't letting me put the drives in a RAID (it lists them, but the option to select the C600-series controller is simply grayed out). Have I done a mistake? Do I need SAS drives to RAID them on the SAS controller?

  • Verify burned CD image

    - by Brian
    Is there a way to verify a CD image (.iso) after it has been burned (and either the CD burning software does not have a "verify" option, or it was not used at the time of burning)? I tried ripping the CD using dd and comparing the md5sum of that image and the original, but they don't match. I didn't really expect them to, but I'm pretty sure this disc burned without errors (I just want to be sure since this is a master disc to be sent off to be duplicated).

  • DIG command is hanging and not timing out as expected

    - by igalvez
    I ran into the following issue by accident when playing around with the DIG command and testing some domain names. Why does DIG hang and not timeout after 10 seconds when executing the following: dig +tries=1 +tries=1 +retry=1 +time=5 +trace google.us.com DIG hangs for about 30 seconds instead of timing out and then dies with the following error message: dig: couldn't get address for 'ns.reserved-domain.uk.com': no more Do I need to set another flag/option for DIG to have it timeout instead of hanging, or is this a bug?

  • Access full BIOS settings

    - by FlxEx
    I recently purchased a Acer Aspire TimelineU M5-481TG-6814, only to discover that the sound isn't working. Through my research, it seems that the most probable cause is that the onboard audio is disabled in the BIOS. However, the option to enable the onboard audio just isn't present in the BIOS. So my question is: is there any way of accessing such settings in the BIOS? Some extra information: link my purchase System BIOS version: InsydeH20 Setup Utility Rev3.7, V1.05

  • Install compiled linux program on multiple computers

    - by jtnire
    I'm sorry if this sounds like a silly question, but when I compile something on linux using the usual "./configure, make, make install" steps, how can I install the programs on other servers without having to recompile? I am trying to avoid having to install the build tools on production servers, however I need the latest version of a particular piece of software, so using RPMs isn't an option in this case. Any help is appreciated. Thanks

  • Outlook Quick Steps - close email after selecting "Done"

    - by PeterX
    Is there a way for Outlook 2010 to close the currently opened-email (if it's in its own window) after I select "Done" from the Quick Steps item in the ribbon? I have investigated the Quick Step actions but I can't see anything applicable. I understand that the "Done" option is available even in the full Outlook window, so closing the current window wouldn't be appropriate here, but it'd be good if it could close it if the email was opened in a new window.

I have a ridiculous number of plugins on this comp otherwise I could just try disabling them one at a time.

  • DHCP server with multiple interfaces on ubuntu, destroys default gateway

    - by Henrik Kjus Alstad
    I use Ubuntu, and I have many interfaces. eth0, which is my internet connection, and it gets its info from a DHCP-server totally outisde of my control. I then have eth1,eth2,eth3 and eth4 which I have created a DHCP-server for.(ISC DHCP-Server) It seems to work, and I even get an IP-address from the foreign DHCP-server on the internet facing interface. However, for some reason it seems my gateway for eth0 became screwed after I installed my local DHCP-server for eth1-eth4. (I think so because I got an IP for eth0, and I can ping other stuff on the local network, but I cannot get access to the internet). My eth0-specific info in /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet static address 10.0.1.1 netmask 255.255.255.0 network 10.0.1.0 broadcast 10.0.1.255 gateway 10.0.1.1 mtu 8192 auto eth2 iface eth2 inet static address 10.0.2.1 netmask 255.255.255.0 network 10.0.2.0 broadcast 10.0.2.255 gateway 10.0.2.1 mtu 8192 My /etc/default/isc-dhcp-server: INTERFACES="eth1 eth2 eth3 eth4" So why does my local DHCP-server fuck up the gateway for eth0, when I tell it not to listen to eth0? Anyone see the problem or what I can do to fix it? The problem seems indeed to be the gateways. "netstat -nr" gives: 0.0.0.0 --- 10.X.X.X ---- 0.0.0.0 --- UG 0 0 0 eth3 It should have been 0.0.0.0 129.2XX.X.X 0.0.0.0 UG 0 0 0 eth0 So for some reason, my local DHCP-server overrides the gateway I get from the network DHCP. Edit: dhcp.conf looks like this(I included info only for eth1 subnet): ddns-update-style none; not authoritative; subnet 10.0.1.0 netmask 255.255.255.0 { interface eth1; option domain-name "example.org"; option domain-name-servers ns1.example.org, ns2.example.org; default-lease-time 600; max-lease-time 7200; range 10.0.1.10 10.0.1.100; host camera1_1 { hardware ethernet 00:30:53:11:24:6E; fixed-address 10.0.1.10; } host camera2_1 { hardware ethernet 00:30:53:10:16:70; fixed-address 10.0.1.11; } } Also, it seems that the gateway is correctly set if I run "/etc/init.d/networking restart" in a terminal, but that's not helpful for me, I need the correct gateway to be set during startup, and i'd rather find the source of the problem

  • Vmware Player network adapters have no network or internet access in Windows 7 enterprise [closed]

    As per the title. My VMWare player installation has setup the two network adaptor VMnet1 and VMnet8 and they are picked up as unidentified networks with no network access (i need this to activate my windows server installation on it). The option to change the network location is not available (this might be because of network policy on the domain despite having set this as configurable in the local security policy section). Is there anyway i can change how these networks are detected or alter the configuration of vmware to get around this?
