Problem with DNS resolution

Hi All,
I am facing a strange problem with the name resolution in mac os x. I have a Lan with a cisco switch and a cisco router that serves as DHCP and DNS server.
In the router I have setup some static host names with the relevant IPs in the local Lan. When ever I try to ping or browse, from within OS X, using the names, I get "unknown host" error. The problem is only with the static hosts I have setup. The strange part is that nslookup and dig give back the correct IP as it is assigned in the Cisco router. When I use my iPhone or iPad everything works fine.
Any help would be appreciated.

Hi Barsam, did you solve this issue?
I have something similar happening to me, I can ping, traceroute, nslookup even use entourage to send and receive emails, but can browse the web with any browser (safari, firefox and chrome)
Last night farefox was working, today I upgrade to the latest firefox version and now firefox stop working saying that can resolve the name, the same error as safari and chrome
I flush the cache, reboot, manually enter DNS, change DNS servers to public ones, but still can't surf the web

Problem with DNS - ping/Safari cannot resolve, but host/dig work OK

Hi All,
Have a weird problem with DNS which is a bit similar to the following ones:
http://discussions.info.apple.com/thread.jspa?threadID=2190208
http://forums.macrumors.com/showthread.php?t=337942
I connect with remote internal network via OpenVPN and from time to time (yes, intermittent problem :)) internal DNS names cannot be resolved.
When it happens I can still resolve names using host or dig utilities, but applications (like Safari) and ping cannot resolve them.
resolv.conf has proper DNS server set:
*$ cat /etc/resolv.conf*
*# Mac OS X Notice*
*# This file is not used by the host name and address resolution*
*# or the DNS query routing mechanisms used by most processes on*
*# this Mac OS X system.*
*# This file is automatically generated.*
*domain openvpn*
*search openvpn*
*nameserver 10.0.0.1*
More than that - it can resolve those internal names when queried directly, for example using host:
*$ host YYY.XXX.ru 10.0.0.1*
*Using domain server:*
*Name: 10.0.0.1*
*Address: 10.0.0.1#53*
Aliases:
*YYY.XXX.ru has address 192.168.x.y*
but at the same time ping reports "*Unknown host*":
*$ ping YYY.XXX.ru*
*ping: cannot resolve YYY.XXX.ru: Unknown host*
I tried "*dscacheutil -flushcache*" and it did not help. Also tried to comment out domain and search directives in resolv.conf and it did not help as well (and actually it should not matter).
Any ideas why this can happen and what else can I check when it happens again?
Thanks!

I have the same issue. It cropped up after I installed updates to MS Office 2008 and Firefox in which I also saw issues with the icons disappearing in the dock of the applications that were open when I started the Office update. I rebooted to try to get them back, but ended up deleting them and restoring from the Applications folder. I don't know if that's a red herring or not, but I generally try to figure out what has recently changed that may cause something to suddenly start failing.
I'd been working successfully all morning before it started acting up. Switching from wifi to cat5 had no effect.
@realaaa, were you able to resolve without a major undertaking, like reinstalling your OS?

Problems with camera resolution...

Hi everyone,
I've acquired a security cam to test a video-chat with FMS2
and encounter a problem with the resolution of my cam. It's a CPcam
CPC371P and It is said to have a resolution of 510*492 (certain
sites speak of standard resolution?).
I wrote two simple applications, one to send the cam stream
and one to receive it, here is the code of both my applications :
Send.fla:
var my_nc = new NetConnection();
cam = Camera.get(IndexCam);
cam.setQuality(0,80);
cam.setMode(510,492,15,false);
my_vid.attachVideo(cam);
my_nc.connect("rtmp://server.no-ip.org/tchat_cam/");
ns = new NetStream(my_nc);
ns.attachVideo(cam);
ns.publish("webcam","live");
receive.fla
var my_nc = new NetConnection();
my_nc.connect("rtmp://server.no-ip.org/tchat_cam/");
ns = new NetStream(my_nc);
my_vid.attachVideo(ns);
ns.play("webcam");
As you can see, nothing really complicated. The applications
work perfectly but no matter the resolution I choose, the image
seems to be extrapolated and pixellised. I tried 512*384,
510*492(supposed to be the cam res) and 240*160.
In any case, the image quality is still really poor...
If anyone could help me on this, Is it a problem with the
camera, I may have forgotten an option in my stream ???
Thanks in advance.
Guaca666.

After many tests, trying many different resolutions, It seems
that It can't go beyond a resolution of 510x480...
Does anyone know if it is the maximum res of a Stream or if
there is an option to outpass this problem ? It may be the cause of
the poor final quality of my video as the camera native resolution
is 510x492...
If anyone could help me, it would be a great relief... :)

Problem with DNS

Hello,
I am relatively new to configuring DNS settings in Server Manager. Recently, my Kerberos relm stopped working and I am now getting this error message on the console:
configured name and reverse DNS name do not match (fileserver.occu-med.com != mail.occu-med.net), various services may not function properly - use changeip to repair and/or correct DNS
I did, for a short time, try to register the server as a mail server. However, due to the many issues I experienced, this was a short lived endeavor. Right now I am running 10.4.11 on an Xserv. The box is functioning as a Fileserver running AFP and SMB, DHCP server, DNS Server, Firewall and NAT, an AD Server, and a VPN server. I have had no issues with the other services, they are all functioning fine. The only problem with OD is that it cannot Kerborize if the DNS is not functioning properly.
I believe that the issue with the DNS can be attributed to the server being part of an external DNS relm as well as an internal DNS relm. There is definitely an entry for mail.occu-med.net in our ISP's DNS server, however on the internal network that I am running, occu-med.com, there is no such entry in our DNS records.
I have tried the changeip command "changeip LDAPv3/127.0.0.1 "externaladdress" 10.0.0.2 mail.occu-med.net fileserver.occu-med.com to no avail.
When I go into the Server Admin took to look at my network connections, it lists connection en0 (The outside portion of the NAT) as mail.occu-med.net. The connection en1 (the inside portion of the NAT) does not have an assigned DNS name.
When I go into the Terminal on the Xserv and type in "hostname" I get "Fileserver.occu-med.com." However when I type in "host fileserver.occu-med.com" I get the error "Host fileserver.occu-med.com not found: 3(NXDOMAIN)" When I type in "host externalip" I get "externalip.in-addr.arpa domain name pointer mail.occu-med.net."
Obviously the server is confused here, but how exactly can I fix the problem?

DNS was working right before the server was propagated to a mai server. I have set up our internal domain to mirror the external domain by entering all of the ISP specific DNS information into the server so that users can access mail.occu-med.com via the internet. I have also set up specific internal DNS names that are not shared with the outside world, such as fileserver.occu-med.com that I do not want published to the external DNS servers. The problem I cannot get around is where the entry mail.occu-med.net is coming from and why it persists. When I was messing around with the mail functions of OS X Server, I deliberately made two different domains, one for occu-med.net and one for occu-med.com. This was short lived as the confusion on where to connect for certain services was giving even myself a headache, let alone my users. Thats when I started delving into setting up our own internal DNS server to provide FQDN services to internal machines. I deleted all of the old information in the server for the previous DNS Zones, but apparently something has not changed.
Using a computer on the inside of my network, if I type into the console host mail.occu-med.net it returns "mail.occu-med.net has address 216.251.43.97"
If I type host 209.234.153.2 I get "2.153.234.209.in-addr.arpa domain name pointer mail.occu-med.net."
So, the server IS providing the wrong information to the internal clients somehow. The problem is that there is no mail.occu-med.net domain even hosted on the server. When I was original messing around with the server as a mail server, I had the connections reversed, en0 was the inside connection and en1 was the outside. I did have DNS working properly when i did this. Is it possible that somehow, while it may not be displayed in the Server Admin window, the current outside interface is still assigned the FQDN mail.occu-med.net?

Problem with image resolution with larger screen size

I was working on Basic Lens Sample (Basic
Lens Sample) for windows phone 8 App. In this the camera by default sets to default highest resolution.
Just had couple of questions on this:
1.) How to change basic settings like resolution,ISO etc.,in this app, because during initial settings
it only takes default value and when I try to change that it throws an error. Also a code comment is written during initialization of camera to take only these default values. So when to change these settings and how?.
2.) How to adjust resolution for phablets having 6" screen. Like when I run the code in Lumia 1320,
the image resolution is not that good and it breaks. So how to adjust screen resolutions for catering different smartphones with different resolutions and screen sizes.
Any solution or suggestions or snippets is very much appreciated.
Thanks In Advance.

Hello,
For you first question, we can use
GetAvailableCaptureResolutions method of PhotoCaptureDevice to get the available resolutions in device. That code sample returns the largest resolution by default, you just need to choose an appropriate one. You can find it in CameraController class in
Models folder in the project.
For you second question, I tested the sample in lumia 1320, I didn’t see the image broken.
>> So how to adjust screen resolutions for catering different smartphones with different resolutions and screen sizes.
You can get an appropriate resolution image and let the OS downscale it for you. You can find the support resolution in the following link. Go to Supported resolutions section.
http://msdn.microsoft.com/en-us/library/windows/apps/jj206974(v=vs.105).aspx.
If you want to display the whole large resolution image in lower resolution device, I think you can use
ScrollViewer control. Use Application.Current.Host.Content.ActualWidth and ActualHeight properties to get the device resolutions, and then you can know if your app is running on a lower resolution device.

Problems with screen resolution after connecting to HDTV with HDMI

Hope that somebody can help with this.
For a while I was connecting my iMac to my HDTV with a HDMI cable and a Mini Displayport Adaptor and had no problems.
The other day when I decided to put the sound through the TV (it was a quiet recording) and switched off the mirror mode my screen on the iMac went very strange.
The left of the screen was very skewed with strange colours and the actual wallpaper and icons was only on the right-hand side of the screen (I couldn't see the time, some icons, etc). The mouse pointer wouldn't go onto the left-hand side of the screen.
I have updated the software and when I now restart it - the resolution is incorrect and I cannot see the entire screen without scrolling across (although the strange stuff on the left-hand side isn't there). Whenever I now connect to the HDTV (using mirror screen) I get the same problem again.
Any help would be appreciated as I am fairly new to Macs.

Do you mean the screen looks like it's zoomed in ? If so then double-tap with three fingers to zoom out, and then make sure that Settings > General > Accessibility > Zoom is switched 'off'

Nouveu_XFCE4_Strange problems with screen resolution

Hallo to all the people out here!!!
I'm quite new to linux. I've been using Ubuntu and Mint for sometime but I decided to switch to Arch, since I decided to have more control over my machines. Before I go on I must clear out that most of those machines are build from old spare items.
in the current machine I'm using nouveau driver with a xfce4 desktop, but I'm unable to set the resolution 1280x1024 to work properly, which I'm almost sure that my screen is capable of.
I managed to set the resolution to 1280x1024 after I manually added new xrandr mode, but there were various strange problems:
1. Windows or panels that were at the bottom of the screen tend to disappear?!
2. In the log in screen (I'm using SLIM)can not see what I type
More than this:
The screen changes resolution during boot
There's a strange sound like flick of a switch every time the resolution changes
I've searched for similar problems but found nothing close to mine, and get more and more confused and i think i'm gonna mess everything up...
Thanx in advance for the help!
These outputs I think that will be useful :

SyncMaster 2243nw problem with full resolution

Hi,
Today i bought a SyncMaster 2243nw monitor.
In the market i tried the same model with my macbook and VGA cable and i got 1680x1050 resolution on the monitor.
When i got back home i tried to get the same resolution but with no luck.
My macbook says that the maximum resolution is 1280x1024 which is not true.
what to do? I tried the same model but in home i have problems. i tried to mirror the monitors and tried to use them seperatly - the result is the same... i just don't know what to do .
pls HELP

You must call set fullcsreen mode before you change the graphics mode. I just started working on such a project last night, and that was a problem I ran into :)

Problem with iSight resolution in iMovie 08

Every time I change the resolution for the iSight camera in iMovie 08 it freezes. It seems to work fine at vga resolution but not the higher resolution that it gives me as an option. It worked one time so far and don't ask me how. After it freezes and I quit iMovie the camera can't be used by any application including iMovie until the computer is restarted. Is anyone able to help me out with this problem? If any more details are needed I would be happy to give them. Thanks.

I've answered my own problem. It has to do with the "created" date; most of these clips came over from my PC, so they all have the same date. By modifying that, you resolve the problem and it reorders the clips.

Seems to have a problem with 1920x1080 resolution, any known issues?

I've just installed V4RC1 on my HP Envy17 and (successfully installed on 2 others and mobile). I'm noticing a alot of flashing when I interact with any site.... even as I type this the screen is flashing in this box.... I'm running at 1920x1080 resolution so wondering if there's something up with that...

I have the same problem too, even with Firefox 4.0 official release. Temporary fix is to disable hardware acceleration and OpenGL.
Hardware is also HP Envy 17 at 1920 x 1080 resolution.

Problems with monitor/resolution after software update

I installed the latest security update tonight, and now my monitor no longer properly works with my mini. I have a Dell 2005FPW. I was using 1680x1050 resolution with no problems. When I rebooted after the update, I noticed my resolution had been changed... and now the mac only detects my display as a "VGA display" and I can't select that resolution any more! The monitor still works fine with my PC.
How can I get my 1680x1050 back??
Mac Mini Mac OS X (10.4.5)

Do you have a KVM switch to share your monitor between your Mac and your PC? I was getting this problem when I got one of these so my new Mac could share my monitor etc with my old one but found a way round it. In System Preferences -> Displays, tick the 'Show displays in menu bar' box. Then click on 'Detect displays' from the drop down menu. The screen will go blue for a moment and the computer will recognise the monitor for what it is.

Help please? problems with screen resolution & external monitor

had a look around this forum and seen many questions about screen resolution when connecting to an external monitor but unfortunately, non that help me answer my problem.
got a brand new macbook a few months ago and today bought a HP v220 22" external monitor.
I am new to the idea of external monitors and am unsure what i am doing wrong settings-wise. it seems that no matter what resolution i set either my macbook display, or the external monitor display to. the external monitor is still not sharp.
Im not sure how to explain what i need but basically i need it to be so that things appear on the external the same size as they do on my macbook screen, so that i will have more space to work in on my external monitor (i am a graphics student) but at the moment what appears on the monitor is lieterally just a magnified version of my macbook screen, hence it lacks clarity.
the highest resolution offered in the menu for my macbook screen is 1280x800 and my external is recommended to be set at 1680x1050.
what settings should i have to get the resolution right?
i will be so so grateful if you can help. i think ive tried every single display setting but to no avail. so please help me!

The 13.3" screen on the MacBook running at 1280 x 800 will have a ppi (pixels per inch) of around 113. A 22" monitor running 1680 x 1050 will have a ppi of around 90. So it is natural that it will look magnified compared with the MacBook. The two displays have different a pixel pitch.
Since there are no monitors with ~113 ppi out there in the market, what you want to do with having the same size and sharpness between the MB and a monitor will not be possible.
If you ran the MB's screen at 1024 x 640 (not even sure if that is an available choice), then the two screens would match in terms of "magnification." But the MB isn't going to look very sharp running such a low, non-native format.

Problem with DNS and/or Virtual Host (works from inside, not from outside)

I am running several web sites (as virtual hosts) successfully on one Xserve (192.168.200), which are accessible internally and from the Internet (via forwarding port 80 on our firewall).
Now I am trying to add another web site (newmini.domain.com), which however is running on a Mac mini (also on the same subnet as the Xserve) at 192.168.100. What I did is make an additional entry under the Xserve's DNS for the domain (domain.com) (+ Machine..., pointing to 192.168.0.100). (I also made the necessary changes to the Mac mini's httpd and hosts configuration--no problem there).
Now, here's the strange thing: All computers on the subnet, whose DNS points to the Xserve, can see and browse newmini.domain.com fine. No problem. The computers ask the Xserve for the IP of the host in question, the Xserve says, "192.168.100", the request goes to the Mac mini, and it serves the web site as expected.
But this doesn't happen if the request comes from the Internet. Instead of seeing the Mac mini, the client sees the default web site of the Xserve... So it appears that somewhere, the virtual host part of the HTTP request is lost between our firewall and the Xserve.
Any ideas? Thanks.

It's not going to.
You say you've setup port forwarding on the firewall. Port forwarding only cares about the port number (80). It knows nothing about the nature of the request (e.g. the hostname that the web request is for). Therefore all extenal connections on port 80 get sent to the XServe. The newmini doesn't see the traffic at all.
If you only have a single public IP address you can only forward port 80 traffic to a single machine. Your options are to either use a different port number, or configure the XServe to proxy the connection to the mini (so now the traffic goes router -> XServe -> Mini -> XServe -> router), although that might not do what you want since it still places load and dependencies on the XServe.

Problems with screen resolution after reinstalling Windows 7 Home Premium

Product Name: HP Pavilion dv6 Notebook PC
Product Number: A6X94UA#ABA
BIOS: F.1C
Processor: Intel Core i7-2670QM
Graphics Device: Intel HD Graphics Family
I recently had to wipe my laptop and reinstall Windows 7 Home Premium (created restore disk from Windows). Ever since, I have not been able to adjust my display settings any higher than 1024x768. My only other option on the adjustment range is 800x600. I have updated BIOS (it was already at latest version) and I have searched for updated drivers (system says most recent ones are in use), but I cannot get it to provide me with a more appropriate size selection for my screen; I have to scroll back and forth in Internet Explorer, for example, to see a full screen because it doesn't fit correctly on my laptop screen.
It seems like this should be an easy fix, but I can't seem to find the right trick. Can anyone help?
TIA,
Teri

@buzymom2 ,
Hello and thank you for posting on the HP support forums. The only thing I would try at this point is to go to this link and download the software and drivers for your notebook.
HP Pavilion dv6-6c53cl Entertainment Notebook PC Drivers
Once you have them downloaded save them to a USB memory stick or burn them to a CD or DVD.
Now you will want to boot into safe mode.
Entering Safe Mode (Windows 7)
Now in safe mode uninstall all your drivers by going into the device manager.
Uninstall or Reinstall a Device
Once you have the drivers removed, reboot into windows in normal mode. Now install your drivers one at a time you have to start with the chipset driver. If you install the drivers without the chipset first it can cause all kinds of problems.
Let me know how things go.
Thank you so much for posting and have a great day.

Having Problems with Low Resolution on Thinkpad Twist

I notice lately that images do not appear as sharp or as deeply colored as they once were. Text looks fine but even looking at high-res images, it's like I'm looking at them with a CGA monitor - I don't see the same color depth and the image appears lower resolution than it actually is. The same pictures look sharp on another computer/monitor. Could this be a display setting? I tried uninstalling and reinstalling the display driver to no avail.
I also notice that when I go from screen to screen, sometimes I get a "ghost" of the previous image. This is not monitor burn-in because the ghosted image goes away when I reboot.

We can't tell from what you've said whether this happens only in your browser. If so, which one and what version? And what happens in other browsers?
