Two Laptops, Same Router/SSID, Different Results

Postby scottmb » Thu Mar 30, 2017 6:25 am

I've been using CS for almost a year now, mostly on my Win7 laptop with hte widget (2.22), but recently on my Ubuntu 16.04 laptop with OpenVPN connecting to the US West nodes.

On my home router, I have the DNS set to OpenDNS to keep the kids out of trouble, but when I want to have some fun, I fire up CS and bypass all that and browse freely.

Typically, it works the same on my Ubuntu box, but lately, when I engage CS on Ubuntu, I cannot even get to the Cryptostorm.is web site - it's blocked by OpenDNS. Checked the VPN connection and it says its good, but I can't get to any sites on the OpenDNS black list - they all display that OpenDNS logo screen telling you to talk to your administrator - as that's me, I'm lost.

Who would CS work just fine on my Windows machine, but no longer on my Ubuntu box? Same router, same WiFi SSID, same CS node.

Any thoughts on what to do or look at on my linux laptop?

You need to edit resolv.conf to contain the DNS server of the TAP adapter, or directly add the CS DeepDNS server of your choice. It sounds like Ubuntu is using your router DNS settings without being specified to do otherwise via resolv.conf

I'd stay off Cisco if i could ** cough **


OpenDNS mostly works at the domain level but I dont see how it is able to figure out someone is bypassing it.

this is strange .... perhaps it is because the Ubuntu OS is not running its own dnscrypt client ?

also, the router should not be hindering CS VPN pre-connects ... as these dnscrypt traffic are obfustcated udp/tcp packets ..,, and that point away from OpenDNS resolver addresses.

Is it possible that the ISP is also employing OpenDNS at the enterprise/edge ?
Such that it is deployed to all its customers' CPE or transparent proxying of all DNS queries is being performed by them ?

I have experienced certain IP ranges on my network that have a mysterious OpenDNS ''administrator'' configuring it for kid-safe usage.

On most occasions the culprit was my ISP ; other times it was another OpenDNS user.

Having to use a previous IP still-stuck-with-these-prior OpenDNS ''administrative'' policies. xD Kinda understand how frustrating it can get when another OpenDNS user has forgotten to ensure that his network's IP changes reflected back to OpenDNS (for the same policies to apply to the newer IPs ).

Btw OpenDNS would not suffice unless your other family members' smart-devices are rooted and configured to strictly resolve via OpenDNS.
non-rooted/non-custom Androids by default fallback on GoogleDNS.
