Network Utility lookup

Apologies if this is posted elsewhere: if so I cannot find it but traffic is so fast moving on these boards at the moment.
It looks to me that in Lion they have removed a useful little feature in the Network Utility - the drop down selection box where you could select different sorts of DNS information to fetch.
Is it intentional? And if so, why, for goodness' sake, remove something that was usefuland replace it with something less so?

Yes, it is strange. nslookup is also a useful command in this context, but again we are talking about a command line tool. The man file fort nslookup cautions that it may not be accurate in Mac OS, but it seems useful enough. The dig command has the same warning.
       The dig command does not use the host name and address resolution or
       the DNS query routing mechanisms used by other processes running on Mac
       OS X. The results of name or address queries printed by dig may differ
       from those found by other processes that use the Mac OS X native name
       and address resolution mechanisms. The results of DNS queries may also
       differ from queries that use the Mac OS X DNS routing library.
So, that's nice.
To answer etresoft's question- it is kind of what others have posted already. In 10.6 and earlier, you could specify, let's say, and MX record and run the query. This is useful information and it is not present in 10.7. It is sort of strange that they removed this. In 10.6 you actually see the dig command output in Network Utility.
The reason we want this feature, for example, might be to determine the priority for a set of mail servers in the MX records.
However, in 10.8 the network utility works fine. I see everything I want to see. I see MX records and all, as long as the actual DNS is configured correctly. Looking at records for a few of my servers, things look great. Looking at a client's server info (the reason why I got on this topic at all tonight) I don't see all I expect to see, and I believe this is why the guy has issues with his email service!

Network Utility - Lookup providing no details

It looks like network utility has changed in Mavericks. I use the lookup feature frequently to get DNS details on domain names, check MX records, NS records, etc. Once I relocated network utility and fixed my shortcut, I found that the lookup tab now provides simply the IP of a domain name, and no additional details. Is anyone else seeing this? Any ideas on a fix, or an alternate app that will provide this functionality?

To get any/all details you want - the keyword is “any”:
E.g.: dig yahoo.com any
I’ve tried the good old Network Utility 1.4.6 in Mavericks but to no avail,

Network Utility Lookup is showing corrupted data

I'm getting corrupted incorrect text data whenever I use the lookup function in Network Utility. DiG in the terminal returns the proper data. The text data is from a Word document I created about 2 weeks ago.
and the rest of the text from the document follows.
I am thinking a host file or something was overwritten accidentally. Can anyone point me the right direction?

I'm not sure I understand your question, but if the hosts file has been modified, proceed as follows.
The easiest way to fix the hosts file is to restore it from a backup that predates the modification, or to copy the unmodified file from another Mac. If you can't do that, then do as below. Please read this whole message before doing anything.
Back up all data. This is a simple procedure, but if you don't follow the instructions exactly, you could be left with an unbootable system. In that case, you'll have to restore from a backup or reinstall OS X.
If you have more than one user account, you must be logged in as an administrator.
Triple-click anywhere in the line below to select it:
open -e /etc/hosts
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). A TextEdit window should open. At the top of the window, you should see this:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1                              localhost
255.255.255.255          broadcasthost
::1                                        localhost
fe80::1%lo0                    localhost
Below that, you'll see some other lines. There should be nothing above the first line "##". If you have any doubt about that, STOP and ask for guidance. Make sure you scroll all the way to the bottom of the document. Scroll bars are hidden by default until you actually start scrolling, so you may not realize that you’re not seeing the whole document.
If the contents of the TextEdit window are as described, close it, then enter the following command in the Terminal window in the same way as before (by copy and paste):
sudo sed -i~ '11,$d' /etc/hosts
This time, you'll be prompted for your login password, which won't be displayed when you type it. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning to be careful. Confirm. Quit Terminal.
If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Log in as one and start over.
That will fix the hosts file. There is now a copy of the old hosts file with the name "hosts~" in the same folder as "hosts". You can delete the copy if you wish. Don't delete the file named "hosts".

For Network Utility: What is "Mailbox Information" in Lookup tab?

I'm familiar with with DNS records, and I've often used the Lookup function of Network Utility to look up IP addresses, cnames, MX records, etc.
Just today I noticed that one of the options from the lookup menu is Mailbox Information.
What is that?
I even tried using it for a few well-known domains (like apple.com), but I don't understand the results.

Thanks, Austin. Littled used is right — virtually none of the domains I checked have anything listed. I tried apple.com, google.com, microsoft.com.
Years ago I learned about DNS from a book called DNS and Bind. The author, Cricket Liu, has his own website at http://cricketondns.com/ and even that lacks a Mailbox Information record.
If Cricket doesn't have one, then I'm not worried about it!
Thanks again.

Using Network Utility

I need to find out the "DNS settings" for a website/blog. What's the best way? Network Utility? Which aspect...
Thanks in advance.
Here is the questions I was asked:
It was suggested that I point our website domain name to our blog so that when people who are used to visiting the web site type in that address, the blog will come up instead. In order to do that, I need the DNS setting for our blog. It's usually a string of numbers like:
362.214.785.898

Lookup in Network Utility can get an IP address ("string of numbers") from a DNS name, for example, doing a lookup on "ford.com" gives a response of :-
Lookup has started…
; <<>> DiG 9.6.0-APPLE-P2 <<>> ford.com +multiline +nocomments +nocmd +noquestion +nostats +search
;; global options: +cmd
ford.com. 900 IN A 136.1.240.248
so the IP address of ford.com is 136.1.240.248
Having said that, I'm wondering why you need your web sites IP address.
Do you host your own web site? Or directly control it's content?
You can make a web page automatically redirect the visitor to another site (google "html redirect"), which may be easier than updating DNS.

Network Utility commands?

I'm taking an Apple exam in the morning (7-7-06). The study guide I'm using has a question (or should I say an Answer) that doesn't seem right. Hopefully someone can help.
Question: Which Network Utility commands can be used to verify connectivity between your computer and a Web server of the Internet? (Choose Two)
a. Traceroute
b. Lookup
c. Whois
d. Finger
e. Ping
I think it's Lookup & Ping, but the answer is suggesting Traceroute & Ping.
Any help would be appreciated!
Phil W

DNS Lookup resolves domain names to IP addresses and visa versa.
Traceroute will actually show you the route all the way to the server if it is connecting to it.
That is true.
DNS Lookup does not actually contact the IP address in question. It merely contacts the DNS server that provides the last known information about the IP address. Therefore the IP address could be unreachable but DNS Lookup would still provide information.

IMAC G4 Tiger 10.4.10 see USB Negear WG111 in Profiler not in network util

Hello,
I have a G4 running Tiger, I have a Netgear WG111 USB V2 it is recognized in System Profiler (as Cohiba 3887 rev0) but network utility does not see it. The driver is loaded into the OS. Any help?
Thanks

Hello,
Thanks for the welcome... I rebooted and looked at Sys pref; Network; show; network port configurations.
I only see the built in products, eth0, firewire, modem. If I try to add one it only gives me those options and 6 to 4.
So it doesn't appear to be recognized, add to that the Netgear app which is for 10.4 is showing in my apps and when I open it it appears to hit the dock as the line moves as if it will add it but doesn't load there. This could be my issue going to try and reload it.

How do I change the saved entry on the "Ping" page of Network Utility?

Whenever I open Network Utility and go to the "Ping" tab I see this:
support.apple.com was one of the first addresses I used on my new MacBook Pro. Is there a way to clear this or change it to something else?
Thanks!

The reason I need to change the file name is we want the breadcrumbing name to change and the breadcrumbing is linked to the file name.
I don't understand this reason. How would changing the file extension solve your breadcrumb issue? Why don't you explain the issue in more detail.

How to have my dial up connection added to the network utility program?

how to have my dial up connection added to the network utility program for monitoring? though i am connected by dial-up, the connection is not monitored by the utility program. the drop down box there does not show the modem at all. ?

Huh? I don't understand what you are asking. I just pulled up the network utility and I don't see what kind of connection monitoring it does for any kind of connection? What kind of information are you looking to obtain? What problem are you interested in solving by having your question answered?

Networking Utility Broken

Hi, I've got a new MBP and I can't launch the Networking Utility in the utilities folder.
When I launch it I get the following error:
You can't open the application "Network Utility" because it is not supported on this architecture.
I called Apple and the first tech couldn't figure it out and I was told that I can't speak with their senior support because I didn't pay for the Apple Care extended warranty. It's pretty annoying considering I've only had this laptop for <6 months.
As far as I can tell everything else works great but I'd like to use the Network Utility
Does anyone know how to reinstall the Network Utility without having to reinstall OS X?
Thanks!

Did you migrate from a PPC machine? How did OS X get to 10.5.3? Have you reinstalled the operating system? Used a utility like XSlimmer or Monolingual? Repaired the hard drive and permissions:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

I accidentally deleted the built in Network Utility and need to restore it.

I'm using OS X Mavericks.
I accidentally deleted the built in Network Utility and need to restore it.
It's not in my Time Capsule back ups. Where do I go with this other than an OS reinstallation?

It should be in your TC backup. If not, you will need to Reinstall OS X
Note that with Mavericks, you need to go to: /System/Library/CoreServices/Applications/Network Utility.app
(You can drag to your Dock, or make this an alias)

When using Network Utility, does Link Speed tell you the actual speed of the network?

I'm trying to see whether a power line adapter I installed in my home network is faster accessing the internet than the WiFi from my Time Capsule.
Using Apple's Network Utility, my power line/ethernet connection reads as being 1Gb/s, which is obviously much faster than the 130 Mb/s of the WiFi:
But are those the actual speeds my iMac is receiving, or are those just what the specs of the device I'm using should be receiving (as in "ideal, what-the-manufacturer claims the speed should be")?

Are you sure you only want to test internet speed?
Internet speed is affected by many factors that are beyond your control - it is also likely that the internet connection is one of the slowest parts of your network.
You may be on an ISP connection that has 'contention' e.g. a shared connection across many users - their use can effect what rates you get. You will probably see different rates for the time of day too. When everyone gets home & starts watching Netflix you can see drops in speed.
Powerline could be many times faster than the internet connection, in which case you will see no improvement because the bottleneck is not the local network - it's the internet.
To truly see if the powerline adaptors are faster you should take the internet out of the equation. It's fairly simple to do if you have a device on your network that supports file sharing. Ideally you would use another Mac connected via ethernet to the network (that should remain the same in all tests). A Time Capsule could be used if you can write data to a sharepoint.
Copy a large file onto that destination & time it.
Repeat on wifi.
It's best to shutdown any background apps to be sure that other items are not hogging all the data transfer. Take many tests to get a decent average.
Divide the file size by the time taken to see a rough figure for the MB/s (MegaBytes per second) bear in mind that network transfer is usually measured in bits/second, so they won't be the same as the link speed figures.
This is generally smart enough to convert if you give it the correct units…

Hi megamike1969,
I've been losing some apps also in the Dock. As Niel said I think is that you may be able to just drag them back to the Dock, if you can find them.
What I do is open Launchpad and while you're in there, drag the application to the Dock. If you can't locate the apps, then disregard this post.

HT2250 I have an Apple network utility that with the previous printer (Canon PIXMA iP 5000) found the printer on the Network for use on a wi fi system but a newish printer (Canon MG6150) does not show up as Bonjour. Is that correct?

Hi Steve,
No expert, but since nobody else has piped in...
Did you setup the DNS Server IP?
