How do I set up file sharing and keep my Firewall on?

When I turned my Firewall on, I lost the ability to share files and screens on my LAN. When I looked at the advanced settings, I saw that File Sharing, Screen Sharing and Web Sharing were already set to Allow incoming connections but other, related, services, AppleFileServer, httpd, kdc, netbiosd, and screensharingd were set to block incoming connections. I reset the latter to allow incoming connections but was still unable to access my computer from another. Once I turned off the Firewall, I was able to access file sharing and screensharing from another computer on my LAN.
I have a firewall built into my external router so I have some protection but I still feel uncomfortable with the Firewall on my computer turned off.
When my firewall is on even with setting up to allow incoming connections, there are lots of console messages like:
1/8/12 3:00:00.882 PM Firewall: Deny netbiosd data in from 192.168.1.2:51619 to port 137 proto=17
They go away as soon as I turn off the firewall.
I did not find the Apple technical article "Set firewall access for services and applications" at http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh18503.html useful at all.
Any ideas as to what is wrong?

I normally have a Firewall enabled. I recently had to do an erase and install of Lion, followed by a one-by-one re-install of all of my software. One of the first things I did was to set up all of my System Preferences the way I like them; Turning the Firewall on was one of them. Later I noticed it was off and turned it on again. I had already set up sharing and was surprised to see the problem when I turned it back on.
As to why do I think it needs to be on. It is another part of my security layer.

How do I set up file sharing to keep my Quicken and Aperture files accessible and in synch across my network?

I have a gigabyte ethernet network connecting my home and workshop. I have an iMac (mid-2009 and late-2012) at each location running Mountain Lion and Windows 7 Home Premium under Parallels 8. I want to be able to access my Quicken (for Windows), Office (for Mac) and photo (Aperture and iPhoto for Mac) files from either location and keep the files in synch. How do I set up File Sharing to accomplish this and what process should I use when updating and saving changes?

Use SugarSync.

How do I set up file sharing in Lion Server to work like file sharing in Lion Client?

I've just installed Lion Server on my home iMac to enable remote access via VPN to my home network.
When the iMac was running Lion Client (before the upgrade to server), and when File Sharing was enabled on the iMac; when other Macs on the LAN connected to the iMac via AFP, they were always able to connect to (share) any mounted external volumes (external USB or FireWire drives connected to the iMac). e.g.
Now that I've upgraded to Lion Server, when other Macs on the LAN connected to the iMac via AFP they are only able to connect to (share) the sharepoints listed in the File Sharing pane of Server.app. e.g.
Is there any way to set up File Sharing in Lion Server so that it works the same way as it does in Lion Client with respect to mounted external volumes? i.e. they are automatically shared? I know I can add each volume manually to File Sharing in Server.app but this gets tedious.
Many thanks!

How do I set up file sharing between iMAC and MacBook Pro?

I am unable to use "file sharing". When trying to connect as a "registered user" it asks for my server password. What is that? I have tried every password I think it could be. I also can not connect as "using an Apple ID"

You can set up "iCloud" on all of them and select there to sync your Documents. You must be running Mountain Lion on the MBA and iOS 6 on the iPhone and iPad in order to use iCloud:

How can I set the file name and folder for output to PDF from another application?

I am developing an application in Microsoft Access where the printed reports are to be saved in PDF format for archive purposes. I can send the output to Adobe X, but the default file name is the Access report name and the folder selected is the one last used.
What I need to do is to create the file with a specific name (which changes for each run) and to a specific folder (which also changes for each run).
The language I'm using is Visual Basic for Applications which is located in an Access form that controls the report production.
Any suggestions, please?

Got it - many thanks.

XP pro file sharing and guest password - how to enable guest password?

Hi,
I want to share files between two Windows XP pro computers. I would also like that these shares can only be accessed with a password.
Here's a description of my setup:
I have two laptops: over 1 yo Fujitsu-Siemens (FS) running on Windows XP pro (finnish) and a brand new Thinkpad T61 (TP) running on Windows XP pro (english). Both of theses computers have guest account enabled and these accounts have also been password protected. FS's guest account is called "vieras" because of the language settings and TP's guest account is of course just "guest". Guest account passwords have been enabled using "net user <user name> *".
I've disabled simple file sharing on both computers, set shared folder permission to only contain these users: TP - "Guest (TP\Guest)" and FS - "Vieras (FS\Vieras)". Both computers have F-secure on them so I've made firewall rules which enable following services both ways to a specific IP: Ping / ICMP echo request and reply ; Windows file sharing and network printers ; Windows network browsing ; ICMP / Internet Control Message Protocol. I've also enabled these services on Windows firewall.
These computers can connect to each other either via Wi-Fi access point (b-mode) or directly using an ad-hoc Wi-Fi configuration (g-mode). Obviously the latter is used for more bandwidth hungry file transfers. Also, sometimes a cross-over Ethernet cable is used as well for even faster file transfers.
Everything on my setup works just fine except just one thing. I connect to a shared resource by running the computer's IP address. When I connect from TP to FS it prompts for username and password. FS accepts both english and finnish names for the guest account provided that the password is correct. But here's the problem... When connecting from FS to TP _no password or username prompt appears_. If I browse TP's shared folder sessions (under My Computer -> manage) I can see that FS is logged on as "vieras" i.e. FS's guest account.
Since I enabled FS's network shares over a year a go I can't remember everything I did to make it work. Every relevant configuration on TP and FS seem to be identical (e.g. "Security settings -> local policies -> security options -> Accounts: limit local account use of blank passwords to console logon only -> enabled") but still TP accepts connections without password prompt.
I've tried to get TP's password prompts enabled for a while now without any success. I did a lot of searching on the subject but I could only find instructions on how to disable guest account password prompts for network shares.
Has anyone had similar experiences or does anyone know what I should try out next? Thanks...
Solved!
Go to Solution.

Success!
I solved my problem by changing guest account passwords. I tried to keep things simple by using the same guest password on both computers. This however allowed FS to log on to TP without guest password for some unknown reason. My logic would tell me that having the same guest password would allow both computers to log in without password but this wasn't obviously the case. I guess Windows has its own logic that I can't figure out or this issue had something to do with different language setups. Anyhow my shares work now like I want them to work.

Use XML.sendAndLoad.
http://livedocs.macromedia.com/flash/8/main/00002879.html
You will need a server script to receive the XML structure
and it depends on
the server scripting language how you obtain that data. Then
you can either
populate a database or write to a static file or even email
the XML data
received from Flash.
For a basic example, I have two links I use for students in
my Flash
courses:

How to configure Growl notifications for File Sharing and Address Book...

Heya,
So my team and I constantly add new contacts to Address Book and drop files via File Sharing and I would love a way to push growl notifications to people's computers when these actions occur. Or even send emails. Does anyone know how I could accomplish this? If so, can you reference a tutorial or guide of some sort? Thanks!

The export function from iCloud creates one single .vcf file with all the addresses in it. If you click on it on the desktop, it starts displaying each and every address as a separate vCard. However, "Tools/Import...Address Books...vCard file" doesn't do anything.

How do I set-up a Shared Folder to automatically grant read

In OS 10.6.8, how do I set-up a Shared folder to automatically grant read & write access to all new MS Office files? Older files are fine. But, when new files are created and saved by one registered user, those files are "read-only" when opened by a different registered user, even though the permissions that are on the "Shared Folder" are read and write for each of the registered user groups. Can't this be changed somehow? The computer is used by two different work groups and some of the WORD or PPTX files are shared by both both work groups and are in the /users/shared folder when one of the user groups creates a new file and saves it to the Shared folder, it can't be edited unless saved with a different name. I need to be able to fix this. I assume it's an Office problem. If I can fix using terminal commands, please be detailed.
Thank you.

For iPhoto 09 (version 8.0.2) and later:
What you mean by 'share'.
If you want the other user to be able to see the pics, but not add to, change or alter your library, then enable Sharing in your iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open the other account. In that account, enable 'Look For Shared Libraries'. Your Library will appear in the other source pane.
Any user can drag a pic from the Shared Library to their own in the iPhoto Window.
Remember iPhoto must be running in both accounts for this to work.
If you want the other user to have the same access to the library as you: to be able to add, edit, organise, keyword etc.
Quit iPhoto in both accounts. Move the Library to the Users / Shared Folder
(You can also use an external HD set to ignore permissions, a Disk Image or even partition your Hard Disk.)
In each account in turn: Double click on the Library to open it. (You may be asked to repair the Library Permissions.) From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.

Setting up File Sharing

I'm running OS 10.5.8. I have a new Grace Internet Radio and I want to play songs or playlists from my Itunes on it. The directions for the radio say to open Sys. Pref. > Internet & Network > the Services section. Then, it says to enable "Personal File Sharing" and "Windows Sharing" and click start for each.
I don't see either of these on the list of services. Anyone have experience with how to set this up? Customer support at Grace couldn't help with an Apple!

Welcome to  Discussions!
Under Internet & Network you should be clicking the Sharing icon, then click File Sharing, then click the Options button you see at lower right. In the dialog that comes up, you need to check the box marked "Share files and folders using SMB".
The instructions included are for versions of OS X previous to Leopard. If you contact their (Grace's) support again, you might want to let them know.

Having trouble setting up file sharing through Airport Extreme

Hi, I am trying to set up file sharing on my USB hard drive through the Airport Extreme, on my HP laptop with Windows XP. I went through the steps in manual setup in Airport Utilities, and my hard drive shows up under the Disk Utility in the Airport Utilities, but the problem is that I cannot figure out a way to find the hard drive from Windows XP. Should it show up in My Computer? I've spent a few hours trying to figure it out and I am close to giving up. If anyone can help me solve this problem, I'd really appreciate it!!!

I have this issue, too. Did you find a solution since you first posted?

Problem using file sharing and screen sharing in Leopard

I have Mac OS 10.5 Leopard installed on 4 computers in a Home Network and have a problem with sharing files and using screen sharing. Here is my setup.
MacBook Pro with my logon ID
MacBook Pro with my fiancee's logon ID
Mac Mini with both of our logon ID's
Mac Pro with both of our logon ID's
The problem I have is I am able to access the Mac Mini computer where we have an external Hard Drive connected for data. She is also able to access it. The only problem is we have it set up to only share this external USB drive. Yet for both of us it shares the external drive along with the internal Macintosh HD. Fortunately this is not a very big deal but since I'm not sharing all those drives why is it doing this?
Also, I am able to connect from the Mac Mini for example to my MBP and vice versa for screen sharing along with file sharing. Yet if she tries to connect to the Mac Pro from her MBP and vice versa it won't. It simply times out and will never connect for screen sharing or file sharing but yet the Finder shows the Mac Pro. We have a 2nd hard drive in the Mac Pro which is the one set up for file sharing. I am also unable to connect to the Mac Pro's HD. Everything appears to be set up correctly. For my MBP on the Finder it shows the Mac Pro but once again I am unable to connect to it for screen sharing or file sharing.
Also, not sure if it's related but even for her MBP she is unable to connect to it from any other computer in our network although it's set up for file sharing and screen sharing so I'm not sure if it's related to her logon ID. Then again as mentioned above neither of us can connect to the Mac Pro.
I tried to make the above sound as simple as possible. I am relatively new to networking and of course Leopard but even on the Mac Pro all settings sound the same as on the Mac Mini where we can both connect to. The only big difference is on the Mini we are connect to a USB external drive, on the Mac Pro an internal drive. Is there something I could have overlooked or are there known issues with Leopard's sharing features?
We both have .mac but since we are using this on an internal network (some wi-fi, some wired, all through an Airport Base Station Extreme) I would think this has nothing to do with Back to my Mac.
I appreciate any help with the above.
