Problems setting up Sharing

I've recently set up a new Mac Mini at work to share its internet connection from Built-in Ethernet (DSL modem) to computers using Airport. This was done in the Sharing control panel in System Prefs, and everything works fine.
I'd like to do the same at home using my 24in iMac. When I open the Sharing prefs pane and click on Internet – Airport is not appearing in the list below where it says "To computers using:". On the Mini that I set up the list contains "Built-in Ethernet", "Airport" and "Firewire", but on my iMac at home the list only shows "Built-in Ethernet".
It would be much appreciated if anyone has any suggestions as to why this is.
Thanks in advance.

Go to the Network preference pane.
From the "Show:" drop down menu, select "Network Port Configurations".
Ensure that AirPort is enabled.

Problem setting up shared connection.

I have recently purchased the Linksys WRT54GS Broadband Router with USB Adapter. The Router is connected via Ethernet to our Cable Modem and the family computer. I have connected my laptop via a Wireless Lan PCMCIA card with no problem. However, I have used the USB Adapter on my sons computer and have had problems every day.
His Wireless Network Connection screen is different to mine. Sometimes it shows that he is not connected to our wireless network, yet is able to use the internet. Other times it says he is connected, but he is unable to get online. If he choses to disconnect himself from the Wireless network, then he is unable to connect again unless the settings are tweaked with.
When I first set-up, I did not secure the connection as I wanted to see if it would work ok, however I have now utilised a secure connection using WEP. We have an assigned key, which is 10 digits in length, but when we go to re-enter they key there is only spaces for 8.
All the settings match those on my laptop, but this problem keeps ocurring. I cannot keep coming and setting up his connection every day. Is there something I am doing wrong? Or any settings that I have set incorrectly.

Since you have changed things around and you are having a problem with just the USB adapter, I'd do this:
1 - With the USB adapter plugged in, in the start menu, right click "my computer" and select Manage
2 - double click Device Manager
3 - Expand "Network Adapters" and right click the USB adapter and UNINSTALL it
4 - remove the USB Adapter
5 - reboot the PC
6 - after all is up again, follow the installation instrctions for the USB adapter
Basically you are starting *almost* from scratch (windows keeps some stuff around), hopefully this will work.

Problem setting up shared printer between PC and Mac with 10.6

I am trying to setup a shared printer between my Mac and PC. I have a HP K80 attached to my PC (which has Vista Home Premium). I have a Macbook pro with 10.6. I have shared the printer on the PC side. From the Mac I have added the printer via Windows Printer sharing, but for some reason I cannot print to the printer. Everytime I try to print, the job just pauses. Is there something I am doing wrong?

Thanks I installed the gutenprint drivers and tried this, and now all working:

Printing to a Shared PC Printer
This article describes how to print from Mac OS X to a shared printer connected to a Windows XP machine. It assumes the computers are already networked and that you can access the PC's files. These instructions are relevant for Mac OS X 10.2 upwards. The instructions may work with Vista. I don't have the means to try it.
1. Find the IP address of your PC - go on Start > Run. Type in cmd and click run. Now type in ipconfig /all and hit enter. This should give you the machine's IP address.
2. Share the printer. Open up Printers and find the one you want to share. Right-click and choose Share. Now click the 'Share this printer' radio button. Now choose a sharing name. Keep it simple - e.g. HP, Office, PC etc.
3. Open a web browser on your Mac and type localhost:631 in the address bar
4. You should now have the Common UNIX Printing System web interface up. Click the 'Add Printer' link.
5. Type a name for the printer, making sure you don't include /, # or space characters. Click continue.
6. Select Windows Printer via SAMBA from the Device list and click continue.
7. For the URI, you need to include a username and password for an account on your PC. You then need to enter a URI in the following format: smb://username:password@ipaddress/printer. So for example smb://johndoe:[email protected]/HP
8. Choose your printer's make, or if you have a PPD file for the printer, choose that. Click continue and choose your printer's model. Now click Add Printer.
9. Done! You now have a list of options for changing the various properties of the printer.
You don't need to be on the same workgroup or domain as your PC, just the same subnet. If both your Mac and PC are connected to the same router, either wired or wirelessly, then you should be on the same subnet.
Thanks guys

I am trying to set up Sharing amongst several computers on my home network. I have followed all the setup instructions but after completion Sharing does not appear in my iTunes window (on any of the computers I've set up). There is no explanation why.

I have been trying to set up Sharing between two computers on my network. I did this once and it worked. However, when I try to set this up now the Sharing feature does not appear on the left side of the iTunes window (on either computer). There is no explanation as to why not. Is this a configuration problem, a network problem or what? Can it be fixed? I have tried turning sharing off and back on on both computers but to no avail. What am I missing? Thanks for any help you can provide.

Hey innerev2003,
Thanks for the question, and welcome to Apple Support Communities.
If, while searching through your past purchases, items are unavailable to download and show a "Purchased" button, they are still on your computer. It may be best to search your iTunes library by clicking Music, then use the search bar at the top right.
If you are completely sure the items are no longer in your library, try signing out of the iTunes Store, and then back in.

Problem using File sharing in a small office network

I have a problem using File sharing on an Imac and Macbook Pro.
My office has a small network running Windows Small office file server 2003. I have one Windows 2000 PC connected to it and 3 Macs, an 2.4 gHz Intel iMac running Leopard 10.5.6 , a MBP running the same and a Mac Mini running 10.5.
From the Finder Shared window of the Mac Mini, I can see all the computers on the network. It also used to be the case for the iMac, but the MBP could never see the Windows PC’s, not the server or the Win2000. This wasn’t a big problem as I was communicating between the Macs and using the shared printer on the iMac.
On Monday Jan 19 the iMac was suddenly unavailable to the other 2 Macs. It was working normally on the Friday. The iMac can access the Mac Mini and copy files to it. The Mac Mini can see the iMac but cannot access it. Even trying to connect as, ends in a failed connection. I have tried rebooting, turning File sharing off and then on again to no avail.
The iMac now also cannot see the Windows PC’s which it previously could.
To get files from the MBP for printing, I now copy it to the Mac Mini and acces the folder from the iMac, a very tedious procedure. I don’t know why this happened and am scared that the Mac Mini is going to do the same thing.
All three computers are also running VMware 2.0 with Windows XP pro, and from VMware the server is visible on all the computers.
Any help will be much appreciated, I live in a small town in South Africa and the local computer suppliers have no knowledge of the Macs.
I think that the problem with the iMac may have started after a software upgrade to 10.5.6 but I am not entirely sure.
Thank you

Well, you're current method sounds pretty good. But if you want to user a file server, hey go ahead.
What you want to do when you centralize project files is to keep track of which one is the newest and becareful not to overwrite files with the same name. So you either have to set up individual spaces on the server (separate AFP/FTP folders maybe), or you'll need to run a file checkout service.
The individual space is cheaper, but it's not much of a difference from backing up to the network drive. Since you have Gigabit connections, you might even opt to save ALL the user files on the server instead of just the project files.
If you want to run a file checkout service, there's two approaches. You can run a service that can host any kind of file, or you can run a version control system for each kind of application (Photoshop, Word, etc.). Please notice, that as you read further and further along, the methods become more and more expensive and complicated. Once you get to this point, it will be necessary to purchase or build software in addition to the Mac OS X Server package.

Problems Setting up my wireless network with an Xb...

Hi, I have had some problems setting up my wireless networking.
I have everything switched on and am able to go online with the laptop and the Xbox with no problems but when I try to share media with the xbox I have problems.
I have opened the ports specified in the setup from xbox on windows firewall and have no problem connection Via Ethernet cable but when using wireless the xbox cannot detect the laptop.
I have checked the network map and both xbox and laptop are connected and have enabled sharing and am running sharing software.
Below is the network map.
I have also been having problems with BT software, the free virus protection will not install, The desktop help will not launch although it shows up on task manager and the installation disk does not launch correctly it doesn't get past the loading screen.
I have had a printer on the wireless network and had no problems printing.
If anyone knows how to resolve this please help.

I have this same Motorola modem and I just verified that my 802.11n AirPort Express Base Station (AXn) can get Internet access with this modem without any issues.
When changing ISPs (or networking equipment) it's always a good idea to start from "scratch" in configuring your equipment.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
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.
Power-up the modem; wait at least 10-15 minutes.
Power-up the base station; wait at least 5-10 minutes.
Power-up your computer(s).
In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), 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.

Problems Setting up NFS

Hi.
I've been having problems setting up NFS on a LAN at home. I've read through all the Arch NFS-related threads and looked at (and tried some of) the suggestions, but without success.
What I'm trying to do is set up an NFS share on a wireless laptop to copy one user's files from the laptop to a wired workstation. The laptop is running Libranet 2.8.1. The workstation is running Arch Linux with the most up-to-date (as of today) software, including NFS.
I have the portmap, nfslock, and nfsd daemons running via rc.conf, set to run in that order.
I've re-installed nfs-utils and set up hosts.deny as follows:
# /etc/hosts.deny
ALL: ALL
# End of file
and hosts.allow as follows:
# /etc/hosts.allow
ALL: 192.168.0.0/255.255.255.0
ALL: LOCAL
# End of file
In other words, I want to allow access on the machine to anything running locally or on the LAN.
I have the shared directories successfully exported from the laptop (192.168.0.3), but I have not been able to mount the exported directories on the workstation (192.168.0.2).
The mount command I'm using at the workstation:
mount -t nfs -o rsize=8192,wsize=8192 192.168.0.3:/exports /exports
There is an /exports directory on both machines at root with root permissions. There is an /etc/exports file on the NFS server machine that gives asynchronous read/write permissions to 192.168.0.2 for the /exports directory.
I receive the following message:
mount: RPC: Program not registered
This appears to be a hosts.allow/hosts.deny type problem, but I can't figure out what I need to do to make RPC work properly.
Some additional information, just in case it's helpful:
This is the result if running rpcinfo:
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper

Thanks for any help here!

Hi ravster.
Thanks for the suggestions. I had read the Arch NFS HowTo and did as you suggested get rcpinfo for the server machine. The Libranet NFS server is configured rather different since the NFS daemons are built into the default kernel.
Since I needed to complete the transfer immediately, I gave up for now trying to set up NFS and used netcat (!) instead to transfer the files from the Libranet laptop to the Arch workstation. The laptop will be converted to Arch Linux soon so I think I'll be able to clear things up soon. I haven't had any problems setting up NFS with homogeneous (i.e., all Arch or all Libranet) computer combinations.
Thanks again.

Ro,
Thanks for the respone, have been playin, with MPLS for last few hours.
The routing between the loopbacks is now working, can PING 7609 Loopback from AS5350 ,and vice versa. (used static routes).
Having problem with TDP / LDP on routers,
mpls label protocol ldp / tdp command works correctly on both routers, but the
tag-switching tdp router-id Loopback0 force
command works on the 7609, but when I add it onto the AS5350 , the command "mpls ldp router-id Loopback0 force" appears on the startup script.
The opposite is true for the 7609 , you add MPLS LDP command, and TAG-SWITCHING command appears instead.
Any Ideas, as different configs of this leave me with forwarding table with both tags added, but not been able to ping the loopbacks !!!
When I can ping bot loopbacks, the OUTGOING TAG , disapears.....
Problem is LOOPBACK Commands on bot routers default to LDP (AS5350) , or TDP (7609). Any Ideas ...

Problems setting up Time Machine using a network drive

I am having problems setting up TimeMachine on my Mac Mini to work with a WD MyBookLive network drive. The network drive came with a TimeMachineBackup shared folder preconfigured. When I first connected the drive to the router and turned on TimeMachine, the TimeMachineBackups appeared as an option when I did "Select Backup Disk" from TimeMachine Preferences.
I managed to successfully connect to the drive and start a backup running. However the backup hit a problem and I started getting an error that the "disk was already in use". I therefore tried to remove the disk to try and start again. Hoever when I now do go into "Select Backup Disk" from TimeMachine Preferences the shared folder on the drive no longer apperas and I only get the option to serach for an Time Capsule.
If I go into Finder, the MyBookLive shows up as a connected Device with all its shared folders showing (including the TimeMachineBackup folder) and my Mac is definitely connected to the drive. How do I get the Drive & TimeCapsuleBackup shared folder to reappear in TimeMachine Preferences so that I can select it as the destination for my backups?

Check around the forum, you are one of very very many. It doesn't matter what WD say, do you see a Certified by Apple notice on it?
Go here, most authoritative site about Time Machine you can find. http://pondini.org/OSX/Home.html

Coercion problem when using Shared Variable

I have a curious coercion problem when using Shared Variables. I want to share the state of a State Machine, which is an enum saved as a control (typedef) called TYPE State (see attached). I create a shared variable called State and define it as a Custom Control, using the just-mentioned typedef. So far, so good. I've attached three simple VIs -- the first one, Init State, simply wires a constant to the input of the Shared Variable to initialize it -- the wired constant is, of course, defined by the typedef. However, the Get State and Set State, meant to wire an indicator (for reading the state) or control (for setting it), develop coercion dots when wired into the Shared Variable. Why? How do I get rid of the dot? [I suppose I could abandon my typedef and custom control, but the beauty of typedefs and custom controls is that it "enforces" rules, lets you use enums for clarity, keeps the code "honest", etc. -- I'd hate to give that up just to get rid of a dot!].
On a related note, the code seems to work. This is much too simplistic to do anything, but if you open Set State and Get State, set the state to anything, run it (it immediately stops, of course), then run Get State, you'll see the chosen state appear in the indicator. So it does appear to work. The "error" (coercion dot) may, I suppose, be a "bug" in Labview because it can't figure out the mapping of the (very simple!) Custom Control, but if so, I hope it gets fixed quickly!

Hello Bob,
I am also seeing this behavior, I will escalate this question to our LabVIEW developers and post again here no later than next Tuesday, November 27th as National Instruments will be closed for the remainder of this week.
If this issue does turn into a product suggestion, I would suspect the workaround would to live with the coersion dot for the time being.
Enjoy the holiday

FINDER disappears after trying to set file sharing. What to do??

‘Finder’ dies when I try to use the GET INFO approach and set a folder to be shared. Finder seems to disappear as soon as I place a check mark in the sharing box. It does not even appear in the FORCE QUIT screen. The computer then is in a state of suspended animation, so I shut off the power. This is a repeatable failure mode.
I used Disk Utility to ‘Repair Permissions” a few times and received some arcane messages when this process was complete … warnings that the following SUID files had been modified and will not be repaired;
- System/Library/Filesystems/AppleShare/afpLoad
- usr/bin/setregion
- System/Library/PrivateFrameworks/Install.framework/Versions/A/Resources/runner
- System/Library/Printers/IOMs/LPRIOM.plugin/Contents/MacOS/LPRIOMHelper
I don’t know what to make of these messages. This stuff may not even be associated with this problem ...
Anyone have any suggestions about how to proceed ??

Today I found another way to crash Finder while trying to set file sharing. Yesterday morning I made Finder disappear, putting my computer in suspended animation, by using the following process; Right click on a folder, GET INFO.>GENERAL>SHARED FOLDER. This caused a crash. I posted a query about this but have received no reply.
This afternoon I tried another approach; SYSTEM PREFERENCES>SHARING>FILE SHARING, then I dragged a folder into the Shared Folders window and dropped it. The folder did not appear in the window. Finder disappeared and my computer was frozen, as before.
So now two approaches lead to the same result; crashed Finder and no shared folder. I’m open to any suggestion about how to cure this problem.

Problems with file sharing

I'm having a lot of problems setting up OS X 10.5 server. Help with any/all of these issues would be much appreciated.
1. Sometimes, the server "forgets" that my administrator account exists. That is, I log off/restart/shut down normally, and then I can't log back in with my administrator account. I use the installation DVD to reset the password for the localadmin account (whose password no longer works), and when I log in as localadmin, my administrator account is gone & must be re-created. The home folder is still there and intact, so once I re-create the account, I can log in from it and my desktop & dock etc are just like they should be. But it's inconvenient to have to keep doing this; it's happened twice in less than a week. Any suggestions?
2. I'm trying to set up a "Group File Sharing Folder" as described in the manual. It says "make sure file sharing service is on and access to the Groups shared folder is turned on". I have turned file sharing service on, but I can't figure out how to turn on access to the Groups shared folder. (I tried going to the "File Sharing" section of "Server Preferences" and clicking the plus and selecting the Groups folder, but when I do so the "Open" option greys out, so it cannot be shared. I don't know what else to try.)
3. Also, when I try to connect to the server from a client computer, the only share that I see available is one called "Empty". But I haven't set up a share called "Empty", and as far as Spotlight will tell me I don't even have a folder called "Empty" on my computer. So how do I get rid of this "Empty"? (If I add a share, it shows up in addition to "Empty".)
4. Finally, is there any documentation about file permissions? I'm coming from Server 10.3, and I'm very confused by files/folders apparently belonging to more than one group/user, and it doesn't seem possible to change which user/group a file/folder belongs to anymore (without going to the terminal). What's going on?

I would create another user in the local domain with a different username that you are certain isn't already used. Give the user administrative privileges. Then the next time that this happens, you can login with this alternate admin user, and determine what the problem is.
Without logging in and looking at the logs and LDAP records, you can only speculate what it might be. Are there two users with the same username, one in the local domain, and another in the shared (network) domain?

Please Help -- Problem w/ ITunes Sharing & Linksys Router on PC

Hi All I appreciate any feedback.
1. I'm no novice..I know how to set up sharing...I had it working before...did some stuff with linksys last week, and now nothing works.
2. I CAN see my other cpu's. I can ping them. I can go to a mapped drive and select a song and play it thru Itunes on my other computer just fine, but the problem is I can't play music thru Itunes sharing. (can't bring up songs, playlists, Podcats, or anything, thru sharing)
3. Both CPU's have latest Itunes update
4. I messed around with the multicast filter, as well as windows firewall enabled/disabled on both machines and none of the above are working. (tried port forwarding on the router as well w/ Itunes Port #'s and that didn't work)
5. It seems like every time I open my cpu on the NON sharing cpu the left side nav has my share folder in it...it hangs..the songs come up, and it disappears right away, giving me No Access to my sharing.
6. I have no password enabled on Sharing
7. Linksys wireless router
8. Both machines are XP SP2
9. I can open and play a music from the sharing computer by going thru windows explorer and play an mp3 on my wireless cpu...so this is weird...
Only problem is sharing won't work...I can't see it in Itunes
Any tips would be appreciated.

Disable the AVG temporarily.
Try a different browswer.

How do I set the shared memory and semaphore Parameters

Hi, everyone:
Could someone help me on this? The Oracle Installation Guide
for Linux says these parameters need to be set, but does not say
how. Thanks in advance.

It seems this problem is getting discussed on a number of

I have a setup similar to yours (384 MB instead of 512 MB),
and I spent some time looking at the parameters.
You CANNOT use the value for SHMMAX from the Oracle manual!
As it says at http://jordan.fortwayne.com/oracle/oralinux.html
"Should you decided to change these parameters, if you set
the SHMMAX to what Oracle says, you are telling the system
to allow a shared memory segment to grow as large as 4 Gigs.
Many users have reported problems setting the value this
high."
Sounds like you are another one of those users, eh?
If you read on down, the guy who wrote that web page never
used over 128 MB for SHMMAX. I'd take a strong hint from that.
=====
Oracle wants you to use 4GB-1 as the SHMMAX value. That
equates to (1<<32)-1. As we shall see, that is not allowed
without "breaking the rules" for the i386 architecture.
If you carefully read through the header file, you will find
out that the **actual maximum value** for SHMMAX is 256 MB.
You can tell this two ways. Take a look at the file at:
/usr/src/linux/include/asm/shmparam.h
Near the top of the file is:
/* address range for shared memory attaches if
no address passed to shmat() */
#define SHM_RANGE_START 0x50000000
#define SHM_RANGE_END 0x60000000
Note that the above is 256 MB (0x10000000), or (1<<28). This
is one potential source of trouble. I don't know if some other
files someplace else in the kernel specify uses for address
ranges adjacent to the above range, which I take to be the
"practical maximum" without redefining that range. Personally,
I wouldn't want to mess with the above unless I **really**
knew what I was doing (and I'll be the first to admit I don't).
=====
Farther down you will see some more lines (not together)
that look like this:
#define SHMID_BITS 7
#define SHMIDX_BITS 15
* SHMID_BITS + SHMIDX_BITS must be <= 24 on the i386 and
* SHMMAX <= (PAGE_SIZE << SHMIDX_BITS).
#define SHMMAX 0x2000000 /* max shared seg
size (bytes) */
Now, 7 + 15 is 22, so you could go up a couple of bits if you
had to. To avoid making the table any larger, I would suggest:
#define SHMIDX_BITS 17
But, 17 turns out to produce a result larger than the "practical
maximum" (256 MB) above. To see why takes a little more
explaining.
If you don't change this at all, then the maximum possible
value for SHMMAX is 4096 [the PAGE_SIZE) << 15 [_SHM_IDX_BITS],
or rather (1<<27).
Now, that is exactly half of the (1<<28) "practical maximum" I
mentioned above.
So, if you always want the maximum amount of shared memory,
then change the definition of SHMMAX to the following:
#define SHMMAX (PAGE_SIZE<<_SHM_IDX_BITS) /* max shared seg
size (bytes) */
That gives you 128 MB in and of itself (as compared with 32 MB
as Red Hat 5.2 is delivered).
If you want the full 256 MB that is allowed for in the memory
map, then you need to also change:
#define SHMIDX_BITS 16
The above value is **exactly** what is recommended on the web
page you were following (above).
If you want to keep going up, you will need to change the
memory space allocated for shared memory as defined by
SHM_RANGE_START and SHM_RANGE_END, something I advise against.
=====
Even on a machine with 512 MB of "real" memory, I find it hard
to believe that there would be any substantial benefit to
having a maximum shared memory space greater than 256 MB. The
reason is that Oracle can use multiple shared memory spaces.
It requires a minimum of ten (10), according to the installation
manual, but the Red Hat 5.2 distribution supplies SHMMNI (128)
of them. That will allow each Oracle process to have a total
of up to 32 GB of shared memory (128 times 256 MB) and all it
asks for is 40 GB (10 times 4 GB), so it has plenty, IMHO.
=====
Let me say a few more words about the web page you were using
for configuration advice. That person actually **reduced** the
amount of shared memory segments by specifying **lower values**
for SHMMNI and SHMSEG.
I'd **STRONGLY** recommend **NOT CHANGING** those other values!
Its my understanding that Oracle can make up for the smaller
maximum shared memory segment size by using more shared memory
segments. So, if you reduce those, you are essentially shooting
yourself in the foot by taking away what you are giving with
increasing the maximum segment size.
=====
Good luck, and may this farce be with you!
