  • Fix/Bypass "Cannot connect to the real website-blocked" error in Google Chrome with OpenDNS blocking

    - by George H
    I have a large problem with Chrome in my organisation. I use DNS to manage web site blocking, for sites which are not appropriate and are potentially a risk to the organisation where I do this. I only want to use Chrome over the network, as Internet Explorer has compatibility problems with some sites that we use (We cannot change this either or use different sites). Therefore using internet explorer is not a solution. I do not want to install a different browser, for multiple reasons. Mainly because of the difficulty of rewriting the customised add-ons that we use. However, recently, I have had lots of problems with Chrome SSL Errors. I cannot use my custom OpenDNS block pages, which uses the contact form to request an unblocking. Chrome often blocks OpenDNS for sites (a good example is Facebook) that request HTTPS. Some sites like https://internetbadguys.com (OpenDNS example) This means that chrome refuses to load the blocking page, explaining that the site is blocked. Instead they often call IT support, but they want a solution, as they are sick of getting lots of SSL errors. I have tried looking into ways to turning this off. I have tried: Typing "proceed". That didn't work. Typing "proceed", pressing enter. Didn't work I cannot find phishing and anti-malware any more in Chrome, from the internet guides. Not using HTTPS. However there is an automatic redirect to HTTPS on most sites. Therefore the error keeps coming up. Checking my clocks. They were correct. Does anyone have an idea on how to disabling, bypassing or working around this "feature"? EDIT: This is an example what I am talking about - I found that on google images. I do not block google. EDIT 2: My clocks are correct. I cannot stop using OpenDNS either. EDIT 3: My question is: How do I stop chrome from refusing to load pages that are blocked by OpenDNS, where the server has explicitly requested HTTPS.

  • Secure openVPN using IPTABLES

    - by bob franklin smith harriet
    Hey, I setup an openVPN server and it works ok. The next step is to secure it, I opted to use IPTABLES to only allow certain connections through but so far it is not working. I want to enable access to the network behind my openVPN server, and allow other services (web access), when iptables is disabaled or set to allow all this works fine, when using my following rules it does not. also note, I already configured openVPN itself to do what i want and it works fine, its only failing when iptables is started. Any help to tell me why this isnt working will appreciated here. These are the lines that I added in accordance with openVPN's recommendations, unfortunately testing these commands shows that they are requiered, they seem incredibly insecure though, any way to get around using them? # Allow TUN interface connections to OpenVPN server -A INPUT -i tun+ -j ACCEPT #allow TUN interface connections to be forwarded through other interfaces -A FORWARD -i tun+ -j ACCEPT # Allow TAP interface connections to OpenVPN server -A INPUT -i tap+ -j ACCEPT # Allow TAP interface connections to be forwarded through other interfaces -A FORWARD -i tap+ -j ACCEPT These are the new chains and commands i added to restrict access as much as possible unfortunately with these enabled, all that happens is the openVPN connection establishes fine, and then there is no access to the rest of the network behind the openVPN server note I am configuring the main iptables file and I am paranoid so all ports and ip addresses are altered, and -N etc appears before this so ignore that they dont appear. and i added some explanations of what i 'intended' these rules to do, so you dont waste time figuring out where i went wrong : 4 #accepts the vpn over port 1192 -A INPUT -p udp -m udp --dport 1192 -j ACCEPT -A INPUT -j INPUT-FIREWALL -A OUTPUT -j ACCEPT #packets that are to be forwarded from 10.10.1.0 network (all open vpn clients) to the internal network (192.168.5.0) jump to [sic]foward-firewall chain -A FORWARD -s 10.10.1.0/24 -d 192.168.5.0/24 -j FOWARD-FIREWALL #same as above, except for a different internal network -A FORWARD -s 10.10.1.0/24 -d 10.100.5.0/24 -j FOWARD-FIREWALL # reject any not from either of those two ranges -A FORWARD -j REJECT -A INPUT-FIREWALL -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT-FIREWALL -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT-FIREWALL -j REJECT -A FOWARD-FIREWALL -m state --state RELATED,ESTABLISHED -j ACCEPT #80 443 and 53 are accepted -A FOWARD-FIREWALL -m tcp -p tcp --dport 80 -j ACCEPT -A FOWARD-FIREWALL -m tcp -p tcp --dport 443 -j ACCEPT #192.168.5.150 = openVPN sever -A FOWARD-FIREWALL -m tcp -p tcp -d 192.168.5.150 --dport 53 -j ACCEPT -A FOWARD-FIREWALL -m udp -p udp -d 192.168.5.150 --dport 53 -j ACCEPT -A FOWARD-FIREWALL -j REJECT COMMIT now I wait :D

  • Best method of transferring files over internet?

    - by EsotericHabit
    I have a seedbox (running Ubuntu 9.10) at my (parent's) house and will be leaving it there once I go to college this fall. Currently I'm using samba to transfer files between computers, but I was wondering if once I am on my university's network, whether using FTP would be a better option versus samba over a VPN. The files will range from 100 MB to 17 GB, if that matters. Would one be more efficient over the other? Did I forget any other options?

  • Squid authentication encryption

    - by barbarossa12d
    Hi, I use Squid and the users must authenticate. The users are authenticating in cleartext. I found tutorials about stunnel (http://www.jeffyestrumskas.com/?page_id=3), but the clients also need this software. Is there no possibility that for user authentication SSL (or some other encryption technology) can be used?. Thanks.

  • Digital signatures and encryption in GMail

    - by Antonio
    I just wonder if there is a way to use SSL certificates or PGP keys for signing my email. At the moment I have to setup S/MIME in Outlook (or another thick client) to send signed messages via SMTP. It works for me, but I'm looking for a way to do the same using GMail's web interface.

  • VPN access configuration with ForeFront TMG

    - by Yang
    I am trying to configure VPN Client access with ForeFront TMG. When I try to add domain groups to allow access to them, under Group column I can only see the SID of the domain group. And the Domain column ends up empty. ForeFront TMG is joined to the domain. Can you think of a reason?

  • secure data transport between web server and database server

    - by atypicalgeek
    I asked this question in stackoverflow and it was suggested to try here so here goes... I'm planning on provisioning a web server and database server in a server farm environment. They will be in the same network but not in the same domain, both windows server 2008 and the database server is sql server 2008. My question being, what is the best way to secure data in transport between the servers? I've looked into IPSEC and SSL but not sure how to go about implementing either.

  • Net send question

    - by somacore
    I'm on a work laptop. If I do a 'net send' to all computers on the domain while not VPN'd into the network, and it says it's successful, one of the following is true: It failed, but thinks it's successful, and it won't send anything. It failed, but it will send next time it's on the work domain. I know I was off the domain when I sent it (I made sure of that first). What will happen?

  • Windows 7 Remote Desktop Connection Rendering Each Frame?

    - by TheDarkIn1978
    When connecting to my work computer over VPN and Remote Desktop Connection, images and videos are sent back one frame at a time, which really slows things down. I'm familiar with the "Experience" tab while connecting and the only options I have checked are "Visual styles" and "Persistent bitmap caching". Isn't it possible to work remotely that is more similar to screen sharing over Skype, where there is a lag but not every single frame has to be rendered and passed back to me one at a time? Both computers are running Windows 7 Professional.

  • Peer to Peer solution for LAN over Internet

    - by Coyote
    I need to emulate a LAN between some machines over the internet to play some LAN only games. I remember that there was software that could do this, but don't remember what it was called. Anyone heard of this, or know of similar solutions that won't require a lot of work? The game is fun, but not fun enough to bother with setting up a VPN server. ;-)

  • JavaScript-based applications and text browsers

    - by Vi
    How to use complex AJAX applications with a lot of menus and with X.509 authentications in non-GUI mode with simple browsers? For example, I can login to Webmoney from console using links/lynx/link2 (but not w3m), entering captcha (using aaxine) and do operations there, but can't login not using X.509 certificate (even if I try to separate SSL part using "socat tcp-l:... openssl:...:443,cert=extracted_from_firefox.pem") Is there some program that behaves like fully-fledged browser (build DOM/execute JS/Support all features except of actually displaying things), but without GUI and dependencies on GUI libraries?

  • .htaccess redirection resulting alias plus directory name

    - by austin cheney
    I am using .htaccess file to redirect all web traffic in a folder to ssl, because the directory prompts users for a login. When a user logs in they are redirected from https://subdir.mailmarkup.org/ to https://subdir.mailmarkup.org/~homedir/subdir. I want users to be redirected from http to https, and this is occuring successfully, however, I do not want users redirected from the first path mentioned above to the second. How do I prevent this?

  • Is it possible to open server ports on TUN devices?

    - by JosephH
    If I make a VPN connection to a server (say myvpn.com; assume this server is not behind any router/firewall) via a TUN device and open a port (say 5555), will someone else be able to connect to me via myvpn.com:5555? If not, is there a tunneling software that does exactly this in a transparent manner? i.e. run any TCP/UDP-based server instance behind a router without NAT using another remote server.

  • Create a redirect for IIS7

    - by justSteve
    When i created my (server08/IIS7) server's SSL certificate I mistakenly defined the common name to be 'myDomain.com' instead of 'www.myDomain.com', meaning that https://www.myDomain.com comes up untrusted. I understand that I can create a server redirect to correct the problem but I don't see where/how to do that from IIS's server manager. thx
