Networking and DNS issues

I am trying to get my domain set up and I am running on two routers. The first router is set up on a 10.0.0.1 network, and my network is on a 192.168.1.1 network. I am able to get out to my ISP via port forwarding, but I am not able to set up a DNS. The
wizard runs me through the forward lookup zones and my servers IP address in validated, but then it says that the DNS could not be created. Also, my product ID is not able to be activated because the activation server reported that the product key has exceeded
its unlock limit. How do I fix this?

Make sure local DNS server has a static address and own address as primary and 127.0.0.1 as secondary (assuming only one DNS server) in network connection properties and is not multi-homed. Also put public DNS addresses as
forwarders only on local DNS server. Client should have local DNS address
ONLY so client can find and logon to domain.
Posting an unedited ipconfig /all may also help.
Start, click Run, type SLUI 04, and then click
OK for phone activation.

Network and DNS Setup Issues

I am setting up an Xserv with Snow Leopard at my school, and I'm running into DNS issues.
I followed the excellent guide at http://labs.hoffmanlabs.com/node/1436 and believe I've set DNS up correctly, but I fail the changeip -checkhostname test (I've replaced my domain and server names):
mserver:~ admin$ sudo changeip -checkhostname
Primary address     = 10.10.10.2
Current HostName    = myserver.mydomain.ns.ca
DNS HostName        = myserver
To fix the hostname please run /usr/sbin/changeip for your system with the
appropriate directory with the following values
   /usr/sbin/changeip 10.10.10.2 10.10.10.2 myserver.mydomain.ns.ca myserver
dirserv:success = "success"
I tried running the command as given, ("sudo /usr/sbin/changeip 10.10.10.2 10.10.10.2 myserver.mydomain.ns.ca myserver") but that didn't solve it. I'm not sure if that's the correct thing to do, or why that didn't work.
I have come to suspect that my issue is with network settings, and would appreciate advice on what I'm trying to do. The server (our only one) will be an OD master, a file server and a web server. It is inside our router, with an externally-reachable IP address and an internal one (the latter is 10.10.10.2). I have configured it with the two IPs on one port to avoid the issue with SL wanting two serial numbers. My System Preference > Network settings are as follows:
Ethernet 1b (highest service order):
IP Address: 10.10.10.2
Subnet mask: 255.255.255.0
Router: 10.10.10.1
DNS Server: 127.0.0.1
Search Domains: mydomain.ns.ca
Ethernet 1 (second highest service order):
IP Address: <my external IP>
Subnet mask: 255.255.255.248
Router: <my ISP's router>
DNS Server: 127.0.0.1
Search Domains: mydomain.ns.ca
Ethernet 2:
Not Connected
Although I'm unsure what it means (I'm more a teacher than a techie!), Server Admin > Settings > Network shows:
Computer Name: myserver
Local Hostname: myserver
Network Interfaces:
en0; IPv4; 10.10.10.2; myserver.mydomain.ns.ca
Ethernet 1 (en0); IPv4; <my external IP>; myserver.local
The second of the interfaces above is bold.
The big issue I'm seeing on my network (possibly as a result of this, but everything I've seen says fix DNS first) is that network users can't log in although they have homes and can connect to the homes once logged in as local users.
Many thanks in advance for your help--the school year is closing in quickly!
Regards,
Alex

Thanks. I disabled the external IP & rebooted. Server Admin now has only the one IP. But I still get the same result:
myserver:~ admin$ dscacheutil -flushcache
myserver:~ admin$ sudo changeip -checkhostname
Password:
Primary address     = 10.10.10.2
Current HostName    = myserver.mydomain.ns.ca
DNS HostName        = myserver
To fix the hostname please run /usr/sbin/changeip for your system with the
appropriate directory with the following values
   /usr/sbin/changeip 10.10.10.2 10.10.10.2 myserver.mydomain.ns.ca myserver
dirserv:success = "success"
myserver:~ admin$
I ran dig on a client:

Double computer name on network and NAT issue with Back to My Mac

These are the problems I am having:
When my MacPro workstation (which on the network is named "The Beast") wakes from sleep - I get a message saying "there is already a computer on the network with the name "The Beast". Other computers on the network can now find you at "The Beast-2"" and it gives me a new name in the file sharing preferences - even though it is the only computer on the network with that name.
Why is this happening???
The other problem is with BackTo My Mac - When I try to enable it - I get an error message saying "Turn off NAT Addressing" - which I thought was turned off since the AEBS is in Bridge Mode. Why is this happening?
Here is my network setup which consists of the Modem / Router from my ISP - an Airport Extreme Base Station and one Airport Express - which is connected to my MacPro via ethernet. The MacPro does not have an airport card installed and is running OSX 10.6.8 - all other computers / devices are running 10.7.x and iOS6).
VDSL Modem / Router (from Internet provider) with wireless turned off - (so it is not broadcasting a competing wireless signal) - connected via ethernet to my Airport Extreme Base Station.
Here are all the settings on the AEBS and the Airport Express: - I am using Airport Utility 5.6.1 on my Mac Pro running OSX 10.6.8 - so the setup prefs are different than the newer version of Airport Utility found on 10.7.x systems - but both work fine. Although I did notice that the option to allow ethernet clients to connect to the Airport Express does not exist (or I just didn't find it) in the newer version of Airport Utility.
Airport Extreme Base Station is set up as follows:
Wireless Mode: Create a Wireless Network
Wireless Settings:
Allow this network to be extended IS CHECKED
Radio Mode: 802.11n (b and g compatible)
Wireless Security: WPA/WPA2 Personal
Access Control:

Internet Settings:
Internet Connection:

Connection Sharing: OFF (Bridge Mode).
TCP/IP:

MobileMe:
Back to my Mac is turned off - but if I try to turn it on I get an error message saying "Turn off NAT Addressing - which I thought was turned off since the AEBS is in Bridge Mode. Why is this happening?
IPv6:
IPv6 Mode: Link-local only
As stated - my MacPro with no wifi card - is connected via ethernet to an Airport Express which connects wirelessly to the AEBS for network and internet access.
Airport Express Settings:
Airport Settings:
Wireless Mode: Join a Wireless Network
Allow Ethernet Clients IS CHECKED
Wireless Security WPA/WPA2 Personal
Internet Settings: Are grayed out (as in I can't change these settings - I assume because they are being controlled by the AEBS) and read as follows:
Connect Using: Wireless Network
Connection Sharing: OFF (Bridge Mode)
TCP/IP:
Configure IPv4: using DHCP
All other settings are identical to the AEBS.
All other WiFi devices in the house (MacBook Pro, iPhones, iPad's, iMac, Apple TV, Nintendo Wii etc…all are able to connect to the network and connect to the internet - no problem.
Thanks for any insights into what might be causing the double name on the network and why it is asking me to turn off NAT addressing - when both my Airport devices are in Bridge Mode?

I am also having this issue... any updates on this??

[SOLVED] Greetings... and DNS issues... (why is it so slow?)

Hey everybody!
My name is Stephen. I'm new to Arch (hence I'm posting in the newb forum). A bit of background: I'm a CS major in the good 'ole US of A. I used Debian/Ubuntu for 2 years before now. I actually installed Arch just yesterday, so today is my second day of usage. Why do I want to switch from Ubuntu? Several reasons, but they can all be summed up thusly: I want to tinker with and understand how my machine works. I don't want to interface with a blackbox that just "works." Arch seems to be geared towards what I want.
And I've been learning alot, haha. Which I why I am now here to ask for help.
I originally installed Arch at school. Everything was great. Then I took my laptop home and I found out something was wrong. Pacman took an extra 5-15 secs before each download started, but once the download started, I got normal speeds. I observed a similar behavior in my web browsers I tried (Firefox/Surf). No matter what I do, this behavior persists. I suspect this is a DNS issue, and thus I have tried the follow methods of correction so far.
1) Reinstalling to a default configuration.
2) Disabling IPV6.
3) Screwing around with etc/hosts, etc/resolv.conf, and etc/dhcpcd.conf (though I probably did something wrong. Also, I'm not sure how to force Arch to accept my changes after modifying these files.)
I also read somewhere that using HTTP mirrors works better for pacman, but I already was using an HTTP mirror anyway, so I knew that couldn't be the problem.
I have not tried DNS caching yet. However, given that every other machine in the house runs fine, I suspect it is my configuration that is wrong. Does anybody know how I can pinpoint this as DNS for sure? And if so, how I can fix it? Thanks for all your time/help!
Here are some config files/snippets of interest. Most of this should be straight from a basic Arch install.
etc/resolv.conf
# Generated by dhcpcd from eth0
# /etc/resolv.conf.head can replace this line
domain domain.actdsltmp
nameserver 192.168.0.1
nameserver 216.165.129.157
# /etc/resolv.conf.tail can replace this line
Note that 192.168.0.1 is the address of my router on my LAN. I believe the second address is a DNS provided by my ISP.
etc/hosts
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost moebius
::1 localhost.localdomain localhost
etc/rc.conf snippet
HOSTNAME="moebius"
eth0="dhcp"
INTERFACES=(eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)

Having trouble with social networks and connection issues

My iPad won't load any pictures on facebooks website, or the app. It will load google pictures but on Facebook they come up as a blue question mark and it also won't let me log into intagram or snapchat, it says check your network connection. Also my app store won't load. Is there anyway to fix this? I restarted my iPad multiple times and cleared all cookies and data but it didn't help. I had a provisioning profile from an GBA emulator awhile back and I deleted the emulator but not the profile. I recently tried to download the emulator again and this is when problems started. I deleted the profile but nothing seems to work. I have an IPad 2, is there anyway to fix this without going to Apple? I'm not good with all this tech stuff

Airport extreme network and bizarre issue...

Thanks for any and all help but let's start with the setup...
Airport Extreme (dual band) is my main station connected to the modem and also to an imac (wired).
Two airport expresses both using the extend wireless network option
Exp. 1 is connected to the TV through ethernet
Exp. 2 extends wireless network. Used to extend wireless connection to the outside
Now here is my issue. Up until last week my main station was a first generation airport extreme n (fast ethernet).
I tried to add access to the bottom floor with this station and hook up an old pc (no wireless card) to it with ethernet. This works without a problem with an airport express but NOT with the bigger brother...
It will work for about fifty odd seconds (internet and everything), it even has a green light, then boom loses the connection for about 30 seconds (blinking orange). Then back to green... This over and over again. I reset it a couple of times, have even tried to change the firmware to no benefit. I thought maybe it had a reception issue and moved it next to the new main station. Same problem...
Any ideas?
Years ago, I did try to setup a WDS and failed miserably and would like to skip the experience. Are they easier and is that the way to go? If yes, can a relay station (the exp. 1) still send data to the tv through the ethernet port?
Thanks for any and all help.

Here a small update.... I went through the assistant and it took me through a couple of steps and I think at the very end I read setting up WDS. I could be wrong but here a protocol from the affected station.

Airport Express and DNS Issues

Recently I bought a Airport Express and i have been using it connected to a ADSL modem (modem is using PPPoE). Before that i used to have a D-Link wireless router connected to the modem, with no issues. Airport Express is working as bridge mode.
I was having trouble with my Macbook connecting some websites (with Windows computer it was ok), and I could solve it by adding DNS preferred addresses on System Preferences. Although it completely solved my home network problems, every time I go to a place where the preferred DNS is different, I have to exclude the addresses from System Preferences to internet to work fine.
Can anyone help me with that? Is it a Airport Express bug?
Thanks for any help.

That suggests to me that you're expecting the "ADSL modem" to perform router functions. Is it capable of that? What is the brand and model of that modem? If the modem can't perform router functions, your Express shouldn't be in bridge mode.

If something on your LAN is performing proper DHCP functions, that "something" should provide your MacBook with usable DNS addresses without your having to declare them manually.

Mac mini server networking and DNS setup help

Thanks in advance to anyone who can help me with this. I'm working at a small business where I'm the only guy with any IT experience at all, but I'm new to Macs and OS X (<1 year) and being a server admin so please bear with me.
We just bought a Mac mini server as we are expanding from a bunch of workstations and Google Docs. I've just gone through the installation process, but nothing else is on the server, no user data at all, so if the answer is to reinstall from scratch, I can do it.
We'd like the mini to be a file server, print server as well as the gateway for the internet. I realize we could stick to our router and have the server as another node in the network, but we also got a Time Capsule for backing up the server and will locate it in another room to be another wireless access point there.
When going through Server Assistant, I didn't really know what to name the machine so I used corp-Server.local for the Current Hostname and corpserver.private for the DNS Hostname (though i actually use a 3-letter company acronym instead of "corp").
However, i realized after setup we'd want to access the server externally by name, so I changed the DNS hostname to server.companyname.com in the Zones tab of the DNS section of Server Admin (edited primary zone name, changed Nameservers entry for both primary and reverse zone).
I don't know what else I need to do though because there are loads of instances where corpserver.private still shows up, like in the Open Directory section of Server Admin (which btw always hangs when I open it) and the Contact Info of users (eg. user email is [email protected]). I also had trouble earlier using Server Preferences and Server Admin either not connecting or not recognizing my login, but that seems to have abated.
I guess my problem is, where else do I change the DNS hostname? Or do I have to change the DNS hostname back to corpserver.private (in Server Admin)? That way, I think at least everything will be consistent, but would I be able to still configure it somehow so that externally, we could access the server by the server.companyname.com URL?
Also, can the mini be a wireless router for the office? As mentioned before, we want to cut the existing wireless router out and use the mini instead (and use the Time Capsule as a wireless bridge).

So the ISP<->router connection can have a dynamic IP address, but the router<->server one should be static? I guess that means I have to set the IP address in the router. I hope I can get access to it. I don't suppose it matters which one I set first?
An IP router does not assign addresses.
A DHCP server does assign IP addresses upon receipt of a DHCP request from a client.
Some routers (and many firewall routers) do include a DHCP server.
A box with a static IP address does not need to send a DHCP request; it has a static address.
You'll need to ensure that the IP address pool within the DHCP server does not overlap the addresses that are manually assigned to your local hosts; the static IP addresses on your LAN.
[Here is an overview of the pieces involved here, and some of the typical terminology|http://labs.hoffmanlabs.com/node/275].
I hate to belabour the point, but I just want to clarify: in my setup where ISP<->router<->server<->clients, where the server is the only machine connected to the router, which one should be the local DNS server? The server, right? So if the DNS server is turned on in the router, I should turn it off? Or do I need both (ie. router for its LAN (to server), and server for its LAN (to clients))?
So to confirm, the configuration includes (probably) a modem, a router (firewall) and a router (Mac), and then the rest of the (local) show? That is not the simplest configuration, and it's Particularly given that Mac boxes make expensive and slow routers.
The usual configuration is ISP>firewall>LAN and the LAN is usually built from WiFi, wired connections and switches. Within one subnet (which is typical) any host inside your firewall is connected on the LAN, and can communicate (directly) with any other LAN client. The firewall is configured as the gateway; that's the default route for outbound connections.
One more thing that's bugging me: I still don't understand why I couldn't connect to the internet when I plugged in the Ethernet cable from server to router. Even if I was using DHCP to get a dynamically allocated IP, shouldn't it still have worked? I'm worried that I'm going to set up everything as it should be but the connection still won't work.
That's likely because you're trying to use the Mac as a router, and that takes specific configuration steps. It's easier to have ISP>firewall>LAN, and have the Mac OS X Server box and the rest of the stuff as peers on your LAN. If you really want to use the Mac as an IP router, look around for setting up static routes on Mac; there are postings around for that.
If your data is more valuable and your security preferences and requirements are higher, then you may want a firewall with a DMZ, and put your web-facing boxes over in the DMZ. If you're serving stuff to the web or a mail server or such, it's possible to get breached, and a breach means folks can potentially get further into your LAN. With a DMZ, they're somewhat more isolated from your LAN.

Network and signals issues.

I bought new Lumia 925 two months back. Besides other problems mentioned by others, i am adding these. First is, the phone doesn't automatically search for network signals. Suppose i am taking my phone with me through a no signal area like lifts, basements and come back to signal zone i have to manually search for signal and network All times. Second is, to enable data connection i have to restart the phone all times. Third is, when i am getting incoming calls, the slide up doesn't work sometimes and i couldn't attend the calls. Because of these problems, i couldn't use my phone as simple phone. I updated the software and i reset the phone. Still the problems persist.

Hi surenav,
Welcome to Nokia Support Discussions!
Have you tried to remove the SIM card and re-insert it back? Also, is it possible for you to use another SIM card to further check the issue? Is the Network selection under Settings > Cellular already set to automatic? How did you perform the reset? Is it by going to Settings > About > Reset your phone?
Please keep us posted.

Dreamweaver and DNS issue

Ok folks. I am looking for some major help with what seems
like it would be a simple solution. But it has proved to be a very
difficult one.
Here is the story-
I have a website. I use dreamweaver to upload (FTP)
everything. My host recently did some DNS things and changed my IP
address without letting me know. So when I went to FTP somethings
on my website, it wouldn't work. Nor would my website come up on my
laptop. So I got the new IP from the host agent (which now I am
sharing and IP- not sure if that is good???). I am able to FTP with
my dreamweaver. But I cannot see my website!!!!!! I can see it on
everybody else's computer but not my MAC laptop. Does anybody have
a solution for me??? I have tried everything and spent hours on the
phone with Applecare- nothing. It seems like a simple CACHE
problem. Flush the cache and my laptop will be able to go to the
new IP address, right????? But something isn't working because I
have flushed my cache with Terminal, I did it manually with
applecare staff, etc... nothing seems to work and I am desperate.
If anybody has suggestions, please let me know.
Thank you.

RODC Authendication issue and DNS issue

Hi All,
we have domain setup like our primary servers available in different location and we have installed RODC in branch office to Logon and authendicate in local site itself. Enabled GC,DNS in RODC. sites and services created branch office subnet and placed the
RODC server. but the clients belongs in to that branch office still reaching Primary servers instead of RODC. we run the command %logonserver% its showing one of our additional domain controller and when ping our domain.com its getting reply from different
domain controller instead of RODC (Primary DNS server IP is RODC's in IP configuration) and when we do nslookup its showing our RODC server. is that default behaviour if not how do i make it. Please help me to fix this
Thanks, Venkatesh. "Hardwork Never Fails"

Hi,
Have you populated users you have in the branch office in "Allowed RODC Password Replication Group"?
You can also pre-add users that will authenticate to ther RODC to the "Prepopulate the password cache for an RODC". See below links which might help you.

Bizarre problem - networking and menubar issues

Hi all
Odd problem with our 24" iMac at work. It's running OS X 10.4.7.
Over the last few days for some reason the clock, Airport Signal and anything else in the top right of the menubar has disappeared. In addition to this, it seems networking isn't working either as we can't connect to the internet to perform any updates (hence why it's not got 10.4.8 to try to fix the problem!)
Whenever I start sys preferences then go to networking after a reboot it claims to have found new hardware (FireWire). Occasionally, Sys Preferences just crashes instead.
Any ideas?

Michael,
I have been reading the thread and I have the same problem. I looked into the systemlog and found the following entry.

It seems that the iPod file is somewhat corrupt.
What do I do from here ?
Thanks Jochen

So my airport extreme recently had some nat/dns issue and in the airport utility displayed a warning about it and to correct it. I wasn't sure what to do so i pressed the resolve icon and now my guest network is not working.

Anytime you change networking hardware, it is always a good idea to perform a complete power recycle of your networking components.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

DNS and other issues with SBS Server 2003

I see a lot of excellent information out here in the discussion group but I understand little of it. I am technology savvy but not an IT man, so please be patient when I ask questions to clarify your responses.
My first question should be an easy one to answer. Has anyone told you all that they appreciate your help today?
I DO !!! Thank you for your kind nature and your choice to help others (like me)!

Hi,
Could you type “route print“ on CMD, and post the result here?
It would be helpful if you may describe the phenomenon of the problem? such as changes before the problem occurs, any prompt error message, related operations except for these logged Event ID.
You may reference the link below for reference.

Thanks Eve! I appreciate your attempt to help. I inadvertently posted my reply for the Route table without quoting you first. Sorry about that.
As far as the problems go, time to logon to server > 5 minutes. Group Policy issues abound. DNS issues (as mentioned). Thought I had an easy one for you. Sorry about that.
I have one client computer running Windows 7x64 (call it My Workstation) that I back the server and other client PC's up to. The clients have no problem, but after a day or two, the server can no longer "see" the My Workstation and the backup fails.
But then when I reboot the My Workstation, the server "sees" it again!
Furthermore, I backup a 10TB RAID 6 array on
My Workstation to yet another client for redundancy (Call it WORKSTATION2-PC), but if I try to click on the computer icon in Windows Explorer for WORKSTATION2-PC, I get the error "Windows cannot access \\WORKSTATION2-PC. However if I type in
the ip address or WORKSTATION2-PC, I have no problems.

Bit Torrent port forwarding issue and DNS resoluti...

Good morning comunity!
Something odd has happened and I was hoping for some further guidance as I'm not sure what my next steps are.
Background
I have uTorrent running on a a machine that accesses a private RSS feed of torrents I am watching. The client sees a new file posting and automaticlly downloads the .torrent file then proceeds to download the main file itself.
When I had BT installed back on 23 Decemeber I set up port forwarding to this machine, using a static IP, and there were no connection issues.
What has happened
The previous evening as I was going to bed I checked the machine and the active torrents and all my files were sitting at 0 connections for connected seeds & peers. Meaning that uTorrent wasn't able to see anyone to conenct to.
My Troubleshooting
After seeing the above I began checking my connections and set up on the router as well as the machine. uTorrent has within its preferences a port checking utility for its assinged port and that was showing no open connection. I then logged in to my HH4 and verifed my port forwarding rules: nothing had changed there.
I removed and re-added the rules, turned off UPNP as well as turned it on with no success. And during the process of adding the rule back into the system I recieved an error stating that the port was already assigned even though at that moment there were no active assignments. So I changed port numbers and the issue went away.
I then went to chack the private torrent site and the page would not display. Then went to Down For Everyone Or Just Me to check the site as well and it was reported as being up. I loaded my VPN connection to bypass BT's network and I was able to visit the site. Logged back out and did a trace and the trace reported to route to the site. Changed my DNS to Google's DNS setting and was able to access the site.
Where I am now
My torrent machine is now running via the VPN but it's not the best connection in the world as changing the DNS there did not resolve the torrent connection issue.
Does anyone, especially you folkd familar with BT and their practices, have reccomendations as to what to try next or what the issue may be?

A lot of torrent sites are starting to be blocked. Its possible the site in question is being blocked by BT(They have no choice in this as its being forced onto them by a court order same for most of the other big ISPs). If its being blocked you would still be able to access via a VPN so long as thats not being blocked too. In terms of what you can do about it not much other than keep using the VPN.
