OS X V10.7 Lion :: Computer Local Host Name Already In Use On Network
May 10, 2012
After I upgraded to 10.7.4 I receive popup windows informing that: This computer's local hostname "ComputerName" is already in use on this network. The name has been changed to "ComputerName-1.local" every time my Mac wakes up. The number at the end of computer name increases every time I wake my Mac Pro up.
- Disk permissions repair brings no errors.
- After Mac restart - the same result
- As before I use both LAN and WiFi connections with LAN in higher priority.

Before last week, I was always able to go to http://localhost. Now all I get is Unable to connect. I don't care if I go to http://192.168.1.xxx or 127.0.0.1. Still won't work. It use to go to whatever my index.html file was. Now nothing. What might have happened?

Following an online video to learn the proper directory structure, I saw that the author was not running it through MAMP but the local Sites Directory.

Our new Lion Server has a static IP Address pointed to over the internet by our registrar's zone file. Planning the Lion Server installation process with the intent of hosting Web, Mail and Open Directory services to a small number of users who are nearly all located off-site. I do also want Lion Server to be a caching DNS Server and DHCP authority on the local network to replace what dnsmasq does on our current Linux server.
I am looking forward to offloading some of the lower level Linux administration tasks and putting myself in the hands of the Lion Server Setup Assistant and Server App :-) but at the same time don't understand some of its assumptions and fear having to spend a lot of time experimenting and re-installing.
So, specifically, I want the Server App to know that my Lion Server has a "Host Name for the Internet" but that the DNS it sets up will not be the DNS for my zone - I will be managing that through my registrar's interfaces.
Second problem is my fnot understanding what name space devices on the local network will / should use. e.g. The Linux server will be available for backups etc on the local intranet (and optionally have a static ip address on the Internet) but MacBooks, PCs, iPads and iPhones will be served ip addresses by the Lion Server's DHCP. So will / should these dynamic devices have their machine names fully qualified by our domain name with RFC 1918 style ip addresses or something like .local? How do I tell this to Lion's Server App / Setup Assistant? How easy is it to update these initial settings later?

In OSX 10.6, I can use "internet sharing" to set up a wireless network, connecting my wifi enabled music player (or Apple TV) to my MacBook Pro via wifi without actually connect my Macbook Pro to the Internet. However with OSX 10.7 Lion, "internet sharing" requires actual connection to the Internet. Is there a way to disable Lion's requirement? All I need is to stream the music files in my Mac via wifi to my music player (Logitech Squeeze Box 3), and I don't always have access to the Internet. Of course an Airport Express or any router would solve the problem, but that means one more device.Â
Or, is there any other method to set up a local wireless network without actual Internet access? I tried "Creat Network...." in Airport but that doesn't work with passive music player (or Apple TV). It seems only work with computer to computer networking.

'all of a sudden' (so it seems) my 2 printers in my network do not print printjobs from other macs in my network. It dit work. Nothing really changed, exept some system-updates.
print-share is on, awake out of sleep is on (network-tab). Really there is no reason that it would not work. Still, ... it doesn't.Â
config:
- imac 27" 2011, software updated
- macmini 2010, software updated
canon ip4200, works standard on imac. brother HL-2030, works standard on imacÂ
The charm of the set-up was that I could have my printers in the office and still print from the livingroom (mac mini)Â Â To try to solve the problem I moved the mac mini temporarily to the office, so I have it next to the imac.
Opening the section 'printers and scanners' and then pressing the '+' does however give me 2 differentviews:
- on the imac I get a sub menu, dropping down from the '+'
- on the mac mini I get a new window named 'add new printer' (this is hopefully the right translation - I am on a Dutch system)
This strikes me as odd. I never noticed this before. Maybe this is where the problem lies?Â

I am also a newbie to the MAC world and I am loving it. But I do have a question. At my workplace I access the internet via AirPort. I need to access files on other PC's in the office and I cannot seen to find a way. I know on my HP Laptop I was able to access other computers by clicking on network icon. As a side note I never used ethernet port on HP either.

I currently have a media center machine, and my laptop which i use to load my music with. So i am loading my albums onto my laptop and keeping them in the local Music folder, but i have the rest of my music collection stored on my media machine (also a mac). Im wondering if anyone has a solid free solution i can use where it can sync my music folder on my laptop to the music folder on the media machine. I have looked for some on google but they either cost something, or they dont seem reliable. If i could find one that runs on schedule to back up my music every night that would be prime.

(I think) but here we have a NAS (Network Access Storage) that everyone can access. Anyways, on a PC you go to network under my computer (or just computer or 7 now) and in there it is listed along with the other computers on the network. That's all good. On the Mac side you can see it as well, and that's all good. Here is what I am trying to figure out; on a pc in the computer navigation bar you can type addresses. For example the drive was not popping up earlier under the "network", so I just type "//DriveName" into the bar and it opened it up as if I had clicked it.

How do I sync the contents of say, the desktop and documents folders between my Mac Pro and Macbook Pro so the same files are always on both? I only want to do this over the local network because these folders are enormous and I need the syncing done fast.

My Macbook just went out of warranty then my superdrive went out. I need to use it very often so this is a huge problem since I cant afford to fix it. I do however have a compaq laptop running vista that is connected to my macbook via wireless home network. Is there a way I can use the cd/dvd drive to play/burn from my macbook? I would just copy the files over but there is no hard drive space on the PC and I do not have any flash drives I need to burn cds from itunes and I have a project for school I need to burn on a dvd.

Does anyone know how to play the (included on the OSX install) Chess app over a local network on two separate machines? When you select a new game, you have the option to play 'Human vs Human', am I missing something here? Is this only an option for a game between two people sitting in front of the same machine?

Is it possible to use the screen sharing feature from outside my local area network? I would like to be able to share screens with relatives with Macs. I presently have had some success with the use of the Messages > Buddies screen sharing feature through Jabber, but sometimes it doesn't work. The other option is use some service like join.me or team viewer. I would prefer to a program like screen sharing, but without having to deal with my router.

I have five Macs in the house, all of which can see each other on the local wireless network...but...for some weird reason, none but when they try to connect, I get �Connection Failed� after several minutes of silence.
When I click �Connect As...� in hopes of getting a login screen, nothing happens at all. Nada. Zilch. Zip.
The sharing settings on the MacBook are identical to the ones on the other five. Of course, the MacBook can connect the other direction to everyone, including my brand spankin� new MBP.
Any clues, oh wise ones? I�m stumped. What is it about getting into a simple MacBook that has two G4s and two MBPs scratching their heads?

I accidentally deleted my local user account shortcut/alias from the sidebar. I have not been able to see my deleted files through Finder, but can access the files through an application i.e., launching Word and opening a "Recent file." The path that allows me to open the file is (found it under File, Save As):Computer name/Macintosh HD/Users/susan.muehlfelder/.trash/susan local/Desktop1108
1. How can I restore the files in the above path
2. How can I restore the local account to the sidebar allowing me to get back to these files for the future?
3. Will I be able to log back in after I turn off the computer under my local account?
I will leave my MAC logged on until I hear I can turn it off. Thanks in advance for an expedited response as I'm truly afraid to to anything at the moment!

Trying everything from installing ix4000's driver to CUPS driver and so on. The printer works fine when connected to my MacBook Pro but when trying to print on windows xp network.. nothing happens.
Sometimes it says not authorized some time it keeps on trying.Â
When adding a printer I choose windows and I see it and can add it . The driver is available and everything works fine....But it doesn't print or it seems MBP can't send information to that computer which has the printer. The printer on that computer (XP) is shared . Â
I have a Dlink DIR-615 router and we all are connected to it. Should I follow a defined procedure or what? Idon't know what to do . I even couldn't print a single page..

Unfortunately the logic board of my (late 2011) MacBook Pro died. Luckily it was an old unibody model, so I could move my SSD to a similar (albeit older, mid-2009) model and booting up my installation went fine.Â
The only problem I am facing is that I seem to have lost all items in the Local Items keychain, this includes all my Apple Mail passwords and a lot of passwords I entered in Safari. These were very long passwords I generated to be automatically used when needed, for security.Â
It seems that the Local Items keychain is not a .keychain file, but a directory with a SQLite database which is used when iCloud Keychain is disabled. Apparently it just created a new directory with an empty Local Items keychain instead of using the existing one. The name of the directory seems to be an unique ID related to the hardware I'm using.Â
I have already tried to rename my old keychain directory to the UUID of the new one and rebooting, but then it simply renames the user.kb file to user.kb-invalid and starts out with an empty keychain again. I cannot imagine that you always lose all your passwords like this every time your hardware goes defective? I still have the data stored in the login.keychain file, but since I have used Mavericks it apparently does not store all passwords there anymore.Â
how I can migrate the passwords from my old Local Items keychain to the new one?

I have gone through the setup of my newly installed lion server software. I setup a server.example.private host name and have turned on file sharing, and VPN. I bought the server software so I can access my host computer from my IPad and a windows based laptop. When I attempt to setup the profile manager I get to the screen in the directory admin setup that asks for the host name and password, etc. The name and host name are already populated with a generic names and the password fields are blank. Whether I leave the generic fields blank and try and enter a new password or change the generic fields and password to something new I get the same error message every time. It says "Computers host name is invalid. The host name does not resolve to any configured address on this comp. ensure the host name is correct. How do I find out what the correct host name is for my computer?
