I believe this is completely OT, but I want to be positive. I have a fully up to date CentOS 5.2 box. During the past week, when surfing with Firefox (and today, while testing with Konqueror), frequently, especially when DNS is slow, I am seeing references to opendns.com At times, I end up on opendns.com web pages, instead of at the web site I'm trying to get to. My ISP, the phone company, claims this is not coming from their end and that they are not using opendns.com. I was told they have two (2) DNS servers. I haven't changed anything in my IPCop...

A few weeks ago I asked about firewalls and family filters. Lanny Marcus, I believe, suggested OpenDNS. Just wanted to thank him (and everyone here) for their suggestions. Eventually I would like to learn about firewalls, but I don't really want to run another machine at this time. OpenDNS is trivial to set up on the router and looks to be just about exactly what I wanted. Thanks. Sorry to hav...

...SL error, after clicking to get a more advanced report I do not get that error, using Mozilla Firefox 3.0.13 on M$ Windows and I get the report OK on Windows. It appears, when using Firefox on Linux, that it is not ending up on the LinkShare web site and Firefox is giving me the below error. I use OpenDNS.com for DNS service. Question: How can I verify that there is no corruption in my Firefox installation on Linux and that I have the latest SSL CAs for it? TIA!

...apps working great, I just have one specific app that needs to be launched with it's own path, I have tested this specifically with pxelinux.0 from 3.86/4.04 in path/ to verify it wasn't the programs fault. also server address is 192.168.1.12, and is not multihomed Now, 67.215.65.132 is opendns' landing page for all their redirects for invalid domains/etc. Anyone have any clues as to whats going wrong here? Why is opendns' landing page coming up? is pxechain attempting to do a dns lookup that is failing? I do have opendns' servers setup as forwarders for my local dns serve...

...trying other things. A recent unrelated problem affecting the entire LAN apparently enabled me to resolve the repeated winbind crashes. Actually, Steve Langasek provided the necessary clue in December, but I did not know what to do with the info at the time. He said: It's the nature of OpenDNS that if you send a query to it for*any* hostname that doesn't resolve, instead of (properly) giving a "no such host" message, it instead responds with an IP address pointing to one of its own webservers. So any failure to resolve a name via WINS will result in it being resolved...

I have a location using a CentOS 5 server that's multihomed running Asterisk and iptables for internal web access. Recently some sales people got busted surfing some explicit content so the owner wants something in there to block this. I had heard of Dans Guardian and am reading about what's involved here but just wanted an opinion on what's the best solution for this. NTLM silent

...IP to the Tertiary DNS and insert the Primary and Secondary DNS IP's I want to use. Then, I save the file, quit, and restart the network (service network restart). I see messages that the file has been saved and suggesting that I restart the network or the box. The DNS I want to use is that of OpenDNS.com and I saw it work, briefly.Then,it stops working and when I launch the system-config-network GUI again, I see it has reverted to the original configuration, with only the Primary DNS of 192.168.1.1 (the ADSL modem) shown. Questions: The "DNS Search Path" is blank. Is there somethin...

Hi all, I have a problem using named with different CentOS5 servers (2 servers): all they are really slow to resolv any internet address and most of time fails to resolv. This situation differs if I use "forwarders" servers like opendns: resolving names it is really really quickly. And I don't understand why. On the other hand I have tested three DNS servers using Windows 2003, Windows 2008 and Ubuntu hardy and these problems doesn't occurs (I don't need to configure forwarders on any of them): all resolves any...

Hi all, I set up a Samba server (version 3.0.24) names "Lamp" on a Debian Etch distribution. It provides a "guest" (guest ok = yes, guest only = yes, security = SHARE) access to a "share" directory, which works fine. Indeed, I can access \\lamp\share from a Windows machine (named "Ginger") without issuing a password. I can also ping the Linux machine

Hi Rowland > (just a thought, you have given the Samba server a fixed ipaddress, > hostname and domain name, haven't you ?). The Pi has a fixed IP address and hostname. I see: $ cat /etc/hostname RPHS $ cat /etc/resolv.conf # Generated by resolvconf nameserver 208.67.222.123 nameserver 208.67.220.123 So the DNS seems arbitrary. I don't understand what the DNS should be for a

I run "logcheck" on my servers and have noticed that my DC01 log has these: Feb 4 06:58:16 dc01 named[2096]: validating @0xb1c75c18: . NS: got insecure response; parent indicates it should be secure Feb 4 06:58:16 dc01 named[2096]: error (insecurity proof failed) resolving './NS/IN': 208.67.222.222#53 Feb 4 06:58:16 dc01 named[2096]: validating @0xb1c75c18: .

...g? What does it really do? Three more notes: 1) I see no problems in daily operation. All web browsing works as does resolution for local machines. 2) This bind server does not get queries from outside my local network. 3) I use OpenNIC as the "forwarders" servers. I used to use OpenDNS until they stopped handling Yahoo email correctly. Thanks - Bill Gee

Thanks Guus So based of this , having your central tinc server in VPS Provider , will allow potentially the provider to replicate your config files and thus exposing all your remote sites connected. My situation I face is all my remote sites have dynamic addresses ,and in order for me to create a connection point between the sites is to have a central server in cloud with public address. Therefor

...server for those names. In some cases, as I have seen, there are entries that have private addresses. I consider this as being quite bad because it reveals the private address space of the company's/institution's IT infrastructure. What about open resolvers? I am not talking here about OpenDNS or Google, who monitor their infrastructure and maybe they even rate limit the queries per source IP address if too many come from one particular source. I am talking about servers that are not being monitored. I say this because if you monitor your servers and if you understand the DNS techn...

Huh, must be an OpenDNS issue, it works from my phone. I wonder if I'm running into a similar defect on the PC UPS... I could try resetting the driver every few hours (this, in addition to replugging the cable fixes the issue temporarily), but that does feel like a hack that doesn't fix the root cause. I will...

I have a number of updates to C7.6 but now I am getting Cannot find a valid baseurl for repo base/7/x86_64 Did something happen? What do I do ? This machine has internet access and appears to resolve other sites. I get a list when trying to access mirrorlist... Thanks, Jerry

...e VPS seems like the cheapest option and it > works well.. its the security part I have concerns with. > [cut] Same situation for me but I use a dynamic dns provider (there are a lot out there, free and paid : choose by yourself the best for you) coupled with dns-o-matic (a free service from opendns that act as a client for dynamic dns providers, so you gain two propagations of your addresses). So, make a dynamic dns provider account, make a dns-o-matic account, install and configure a ddns client on one or all of your machines or routers, and you can use FQDN for your tinc configurations. I...

...it uses and if it is also your dhcp server, you need to ensure that it supplies a domain name as well as the ipaddress. You also need to check that all the windows machines use the same workgroup name, from your smb.conf 'WORKGROUP' . The dns nameservers '208.67.22x.123' are the openDNS ones, I would suggest you change these to the google ones '8.8.8.8' & '8.8.4.4'. For how to do this and to possibly set a domain name, see your routers documentation. Rowland > > BR > > David >
