Revert Clients to Apple Server

I have a number of clients that used to use Software Update on a server here which is not long gone. How do i revert these back to the Apple servers so they can get software updates? I've found the plist files but cannot find the URL that apple uses by default.
Or do i just delete the software update plist files???
--Tim

Download and use this software, or run 'defaults delete com.apple.softwareupdate CatalogURL' without the quote marks in the Terminal, which is in the /Applications/Utilities/ folder.

What is the recommended number of clients per Mac server? Also what are some recommended specs when purchasing an Apple machine that will have Mac OS X server installed?

What is the recommended number of clients per Mac server? Also what are some recommended specs when purchasing an Apple machine that will have Mac OS X server installed? We have around 300 clients that need to be enroled on the Mac server. I want to know what is the recommended amount of clients a Mac server should contain. Also what are some recommended specs to make sure the server will flawlessly?

Hello cpreasbeck,
Thank you for contacting Apple Support Communities.
I was able to find the following transition guide for Xserve that provides some workload guidance to determine performance when planning a server deployment.
Transition Guide Xserve
http://images.apple.com/xserve/pdf/L422277A_Xserve_Guide.pdf
On page 9, Performance there is a chart that provides maximum numbers of connected users for various activities such as file sharing, mail, web, calendar, directory services and Time Machine and the CPU used as a server (Xserve, Mac Pro, Mac Mini). This information is a bit dated as the referenced software is Snow Leopard Server (OS X 10.6), and the hardware is older also, but it should give you a general idea of what you might need to look for.

Admin Server client not contacting server its running on

Hi All,
I've got an OS X server that for some reason ( probably due to me pratting around) has decided not to have a working server admin prog. I can fire up the client program and point it at any of the IP addresses that the server is listening on and then you get an error message basically saying that the server admin daemon is not contactable.
an ls -lrt in /var/log to see if anything shows up gives me
Jul 31 07:57:38 britten com.apple.SecurityServer[77]: Succeeded authorizing right com.apple.server.admin.streaming by client /usr/sbin/QuickTimeStreamingServer for authorization created by /System/Library/CoreServices/ServerManagerDaemon.bundle.
in secure.log
and Jul 31 07:58:46 [152] kCGErrorIllegalArgument: _CGXCacheMergeShmem: Invalid mergeShmemID (461)
in windowserver.log ... but that keeps happening
I'm running osx server 10.5.7 and my server admin prog is 10.5.3(2789.1.1)
So ...
1). How can i find out if the back end daemon is running
2). what port(s) does it listen on
3). How can I turn on some logging to see what's happening when I run serve admin
4). Any other tips as to how to find out why its not working

Alex

Just as an update, I tried upgrading the server admin tools to 10.5.7 to match the OS release. Although the install seemed to work i.e. I receive an install completed successfully message " when i click on the "About Server Admin" I still see the version number as 10.5.3 I've tried this under my account which has admin rights and form the root user, both with the same result.
Looking in the Server Admin directroy, i can see the timestamps associated with some directories have changed while other things haven't. Could I be running bits of 10.5.3 and bits of 10.5.7?

Apple Server 4.0.3

I am a newbie here working with Apple server. I am in the file sharing area and working on propagating. My server has recently been updated to the Version 4.0.3 with a Yosemite OS and my computer clients are Mavericks OS (except for 2 that are the Yosemite OS..testing the waters). Anyways, I made an error when propagating a student. That then challenged me to go back and correct the permissions on each student so that they could save in their folder. Students can now save their work in their folder BUT cannot export PNG images in a from an animation that they created in the application Hyperstudio to their folders. The same PNG images can, however, be exported to the downloads file on the client computer and then transferred to the student's file on the server. My question is WHY can the students not directly export the PNG animation folder to a student's folder on the server but they can save a Hyperstudio stack into their file on the server? FYI as an admin I can save and export.
Another funny thing, on the 2 Yosemite client computers the students can't save or export, but I can as an admin account. I do understand that admin accounts have more permissions.
Thanks

Try to find a way of reproducing the crash; that is, of making it happen. Without that, only very crude troubleshooting is possible.
Are any messages written to the log (in the Console application) when the crashes happen?

Trying to change server to be a PDC; reverts back to Standalone Server

I'm trying to get my Leopard server to run as a PDC for windows authentication, but when I change the role from "Standalone Server" to "Primary Domain Controller" and click the save button, after authenticating with the "diradmin" account the changed settings all revert back to "Standalone Server" and nothing gets changed. Any clues as to what I need to do? The server is fully updated to 10.5.3, with all other software updates as well.

Hi Topher
I'm guessing you're referring to the post? Well the figure has gone up a fair bit since then. My overall total is quite high as I have been installing servers since 10.2.
FWIW my general rule of thumb is:
1 Format drive, install server
2 On Restart Server Assistant launches (see linked post) don't start any services using Server Assistant
3 Server Assistant does start VNC and enables SSH and the Root Account
Depending on your view SSH and Root are potentially a security problem, deal with these later on.
4 Server Assistant writes settings and preps the server for first use
5 Don't launch WGM or Server Admin. If Server Admin launches, quit it
6 Manually download the latest OS update, don't use Software Update
7 Install this and on successful restart run Software Update again and install the rest of the updates
8 Make sure server is fully up to date before launching Server Admin
9 User server's .local name to log in initially
10 Enable and Configure DNS Service first
I can't stress this enough but if you devote time and energy on this before doing anything else it can prevent a lot of hassle and problems later on. DNS does not have to be running on the Server itself. If you have another server for example you can configure DNS Services on that. You could even use 3rd-Party DNS Software and install on a client machine for example. An old Graphite G4 with DNS Enabler installed is good enough. There are PC equivalents you could use as well. This approach does not require anything in terms of processing power, large drives or even vast amounts of RAM. Reliability and correct configuration is the key.
11 Test and Qualify the DNS Service before moving onto anything else.
Once you are happy enable AFP and SMB. Create a test user in the local node and see if you can access the default share points from a client. Try it with both protocols. Don't be tempted to delete the default share points either. You'll have serious problems if you do.
12 Enable the Open Directory Service
13 Promote to Open Directory Master
If DNS is perfect the Kerberos Realm and search base fields should autofill themselves with information based on the domain name defined in the DNS Service. For example an FQDN of myserver.mydomain.com would result in MYSERVER.MYDOMAIN.COM for the Kerberos Realm and dc=myserver,dc=mydomain,dc=com for the Search Base. I always use the default diradmin name rather than any other. You should not use the local administrator account name
Launch Directory Utility and verify the loopback address (127.0.0.1) is entered as a new configuration. Access Server Admin's File Sharing window and enable the Users folder to automount for home directories. Quit out of Server Admin and launch WorkGroup Manager
Try and get into the habit of only having one or other of the Server Applications open at any one time on the server itself. Its OK to have both open if you are administering the Server remotely if you install them on a client
Authenticate to the /LDAPv3/127.0.0.1 node and you should see Directory Administrator UID 1000 already waiting for you. Create a user and select Advanced. You should see the afp url for the default Users folder. Click create home now and Save. Navigate to the Users folder and you should see a home folder created for that user, inspect the contents of this folder and you should see the usual home folder folders. Quit out of WorkGroup Manager
Launch Server Admin select SMB and go for promotion. Supply diradmin as the user name and its password and you should have the server acting as a Primary Domain Controller
Everything can be achieved using the GUI. There should be no need to resort to the command line although if you want to - as you well know - you can
As for your question? No I have not seen any problems with the 10.5.3 update. The 10.5.2 update has given me a problem on a handful of occasions. The problem was traced - eventually - to failing hard drives.
I apologize for the long post but who knows you might find it useful?

Regarding File being written to Appl server

Hi Pals,
Can we restrict the size of the file that is being written to the application server through Open dataset or any other command.
We have a report which selects data based on a given time period.
The problem we are facing is that even for a period of 1 month the data file written to the appl server is around <b>14-15 GB</b>. Hence we have been asked to split the file that is being written.
However the other option of reducing the time period of seelction has been ruled out by our clients.
Please suggest.
Thanks in advance.
Rgrds,
Gayathri N.

Hi ,

      i_maximum_lines = 99999999.

      v_filect = v_filect + 1.
      write v_filect to v_filecount left-justified.
      fetch next cursor i_cursor
                 appending corresponding fields of table

Com.apple.Server.Accounts error 2 - Local Network Group problem

I am lost :-)
just to specify, this is not a production server, it is just a learning platform for me.
I did a format and start over my server configuration
in order
DNS
DHCP
Open Directory
Profile Manager
User and group
File Sharing
very basic config.
Somewhere during user and group something happen
I did create a new Local Network Group and 2 Local Network User, me and a Directory admin
but now, when I create a group, it seem I can only create local group
and I can't edit Local Network Group
Local Group -> no problem
I can edit Local Group. I can add member
or I can go to a member and add it to a Local Group even if the user is a Local Network User
it work
Local Network Group -> does not work
I can't edit Local Network Group, can't add member
if i go the same Local Network user I added to local group and try to add it to a Local Network group, I get this error
com.apple.Server.Accounts error 2
I dont know where I went wrong :-)
any idea
Thank you

I just reformat and restart the configuration :-( but I might have the same problem again, so i hope to understand why it happened.
I had the problem on both the server and a client machine.
Part of the Local Network User and Groups were greyed out, so I could not edit them
My airport setting for DNS was set to my server, so the client automatically got the local ip of the server for DNS.
On the server, initially, the formatting DNS IP was so to my airport, then I changed it to the DNS of my Internet provider.
but for the self ip 127.0.0.1 i did saw it there at the begining but maybe when did change later it might have been affected.
I did changed the System Preferences>Network setting to a fix IP even if my airport was set as the DHCP with a fix IP for the Mac Mini.
I remember not seeing a DNS in that page. I will check for that now that I am about to start again.
and also, I tried to change the DHCP to be from given from the Mac Mini (like I read in the book) but when I did a
ipconfig getpacket en0
it was still showing the airport as the DHCP server
I will not set it this time.
Thank you
I will come back later with some update
Thank you

TS3276 Mail Connection Doctor says: "Could not connect to Apple Server's STMP. As Verizon is my ISP is this the right STMP? If yes, how do I connect to Apple Server

When using Mail Connection Doctor two error messages come up with regards to sending and receiving mail from my @mac.com account.
The first one says that my @mac.com account: "Could not connect to this MobileMe IMAP server." How do I fix this? Is this caused by the way I have set my preferences? Is this related to joing iCloud? Or my ISP Verizon the problem?
The second one says in reference to my Apple Server: "Could not connect to this STMP server. Check your network connection and that you entered the correct information in the Account perferences. Also verify that the server supports SSL. If it does not, deselect the "Use SSL checkbox in the Advanced tabe of Account preferences." This box was not checked. Two days ago these problems did not exist. Again, how do I figure out who to discusses these problems with?
Feedback is most welcome.

Hi,
Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

Copy file from client PC to server in a web deployed application

I have developed one application using Oracle forms 6i, which is deployed on the web server.
I run this application from a client PC in Internet Explorer using internet.
I want to copy one file from the client PC to the web server.
I have done following things
- Created a shared folder on the server and given full rights to every one on this folder
- I use 'net use' command in my program to connect to this shared folder
- I use copy command to copy file from local client pc to server. This copy command I am executing using host command of my programming (PL/SQL: eg. host('copy abc.txt \\server\share\') )
But this does not work.
When I do the same thing in command window, it works.
(ie. Start-Run cmd to open command window and then type the above copy command)
Can you please tell me, how to copy a file from client PC to the sever in Web deployed application?
Thanks

I downloaded D2KWUtil from the link suggested by you. It has very nice example demo form. But the documentation provided says following
Using D2KWUTIL in Web Deployed Applications
The use of this library is not supported with Web deployed applications.
In a web deployment scenario not all functions within D2KWUTIL will work. Any function that interacts with the User Interface (such as those in the WIN_API_DIALOG package) will fail.
Any interaction with the O/S by other functions will all be executed on the NT server and will act within, or return information pertinant to, the environment on that machine. For instance GET_COMPUTER_NAME will return the Server’s name, not the name of the computer that the Client browser is running on. Likewise COPY_FILE will copy files in the Forms Server not on the Client.
Functions such as those in WIN_API_BITOP will continue to work without change.
so this will not work in web deployed application.
Any other suggestion?
Thanks

How can i load file into database from client-side to server-side

i want to upload file from client-side to server-side, i use the following code to load blob into database.
if the file is in the server-side, it can work, but if it in the client-side, it said that the system cannot find the file. i think it only will search the file is in the server-side or not, it will not search the client-side.
how can i solve it without upload the file to the server first, then load it into database??
try
ResultSet rset = null;
PreparedStatement pstmt =
conn.prepareStatement ("insert into docs values (? , EMPTY_BLOB())");
pstmt.setInt (1, docId);
pstmt.execute ();
// Open the destination blob:
pstmt.setInt (1, docId);
rset = pstmt.executeQuery (
"SELECT content FROM docs WHERE id = ? FOR UPDATE");
BLOB dest_lob = null;
if (rset.next()) {
dest_lob = ((OracleResultSet)rset).getBLOB (1);
// Declare a file handler for the input file
File binaryFile = new File (fileName);
FileInputStream istream = new FileInputStream (binaryFile);
// Create an OutputStram object to write the BLOB as a stream
OutputStream ostream = dest_lob.getBinaryOutputStream();
// Create a tempory buffer
byte[] buffer = new byte[1024];
int length = 0;
// Use the read() method to read the file to the byte
// array buffer, then use the write() method to write it to
// the BLOB.
while ((length = istream.read(buffer)) != -1)
ostream.write(buffer, 0, length);
pstmt.close();
// Close all streams and file handles:
istream.close();
ostream.flush();
ostream.close();
//dest_lob.close();
// Commit the transaction:
conn.commit();
conn.close();
} catch (SQLException e) {

Hi,
Without some more details of the configuration, its difficult to know
what's happening here. For example, what do you mean by client side
and server side, and where are you running the upload Java application?
If you always run the application on the database server system, but can't
open the file on a different machine, then it sounds like a file protection
problem that isn't really connected with the database at all. That is to
say, if the new FileInputStream (binaryFile) statement fails, then its not
really a database problem, but a file protection issue. On the other hand,
I can't explain what's happening if you run the program on the same machine
as the document file (client machine), but you can't write the data to the
server, assuming the JDBC connection string is set correctly to connect to
the appropriate database server.
If you can provide some more information, we'll try to help.

Ical subscription apple server

Hi,
At my company we are using Apple Server Snow Leopard. We have enabled the wiki and the calender.
I have subscribe to the calender (choosed iCloud when prompt) on my Macbook Pro OS X Lion and the events are showing up nicley in my Macbooks iCal
On My iOS Device:
As this is a iCloud calender subscription, when opening the calender on my iPhone 4 with iOS 5, I get the login prompt, I login correctly and all events are shown.
However, when I try to add a new event on the Server/WIKI, the iCal on my Macbook is updated properly but not on my iOS devices (iPhone and iPad 2, both runing iOS 5).
I have notices though, if I go to settings and change the setting from PUSH to manually download and than back to PUSH the calender sometimes updates it self.. but I want it to update all the time as with all the other nice functions.
I have no problem with any other iCloud functions but I'm trying to figure this one out since my company are using the WIKI and Calender on the Apple server and it would be very neat to have the calender shown up in our iPhones.

This has been a frustration for me as well. The answer is no you can't sync your Exchange calendar. However, there is a free (albeit clunky) way of viewing your Exchange calendar in iCal.
You need to install Funambol for Outlook (http://www.funambol.com/) on your office computer.
Then, set Funambol to send (send, not sync) your calendar data to ScheduleWorld (http://scheduleworld.com/).
Then, set up ScheduleWorld to one-way sync (again, one-way sync, not two-way) to Google Calendars (http://www.google.com/calendar/).
Then, go to your google calendar settings page, and copy the Private Calendar URL for your published calendar.
Finally, in iCal, add a subscription, and enter that URL.
Phew! this "solution" works for me, and it's free. The down side is that the computer running Funambol has to be powered up, logged in as you, and connected to the Internet in order for the calendar to be up to date.
Oh, and you have to create user accounts for both ScheduleWorld and Google Calendar.
Ironically, my iPhone 3G has direct Exchange communication, so I can not only view my office calendar, but also update it live. Without the Funambol->GCal->iCal route, I can't even view my office calendar on iCal.
There are other ways to achieve two-way sync between Exchange Calendars and iCal, but none of them are free, or easy as far as I can tell.

Is it possible to lock the keyboard of a client from a server using java

please explain wheterit is possible to lock the keyboard of a client from a server using java

You want to process code on one machine, and thereby lock the keyboard on another machine? No, that's not possible. It is extremely far from possible.
Of course, if the client is running software with security holes in it you might hack into it and crash the thing. This will lock up the keyboard pretty good. I hope that's not what you want ...
Or are you talking about a setup where you already have code running on the client, and some sort of communication between client and server? In that case what you need to know is whether it is possible to lock the keyboard at all. Once you have figured that out, it is trivial to add the communication code to have the server software tell the client software to lock the keyboard.
So what do you mean with "lock the keyboard"? It's pretty easy to remove/disable all keyboard related listeners in your own application. It's a lot harder (and AFAIK impossible with pure java) to disable alt-tabbing out of the application. And impossible, except from exploiting security holes, to lock the ctrl-alt-delete-combination on windows machine.

I would like to know which apple server dictation connects to so that my proxy server will stop blocking it. Which apple server does it connect too?

I would like to know which apple server dictation connects to so that my proxy server will stop blocking it. Which apple server does it connect too?

I would presume so, but it might be worth your while to experiment and play around with different combinations to see if you can block FaceTime while keeping Game Center open. Good luck!
