Multiple user connections slowing down server

I'm running OSX server (latest version) for file sharing & server time machine backups for 7 users. Over time the number of duplicate connected users increases to crazy levels (3,299 total connections for only 7 users this morning!)
I'm guessing that time machine is making a connection when it backs up but doesn't release the share when it's finished and creates a new one every time a machine backs up, hence the number of duplicate shares increases until file sharing is shut down & the number resets.
Has anyone else found this and found a way to prevent these duplicate connections?

We're having a very similar issue. Intel (Nehalem) Xserve running 10.5.8 (9L34). Right after the holiday weekend, AFP clients (all of them) get dropped every 5-10 minutes and their status in Server Admin becomes "Disabled/Asleep". None of the Macs were asleep at the time. I checked idle disconnect setting and it's off. When the client connects again, a new item appears in status list as "normal" until it too is kicked off. This goes on until either I disconnect the phantom clients or restarts AFP. Doesn't seem to affect SMB clients as far as I can tell. A possibly related issue is that the computer list in ARD also goes "gray" at roughly the same time users get kicked. At first I thought it's a network issue since most of the AFP clients are on their own switch while the SMB clients are on another. But the 2 Macs grouped with the SMB clients are getting kicked too. Internet connectivity is unaffected to clients and server. I connected 2 of the Macs to the server via SMB and the connections remain solid. Been pulling my hair out trying to figure this one out. If anyone has any ideas/solutions we would very much appreciate your help!

Multiple users logged into one server, each users printer has a different name, application needs ONE name to print to.

Multiple users logged into one server, each users printer has a different name, application needs ONE name to print to.
I'm NOT in any way a Terminal Services expert and I need help trying to get an application program working in a multi-user environment.
The issue is that the printer changes for every user that is logged in. The application needs to print NOT to the default printer, but to a "special" printer which is selected in the application... let's call it a label printer to simplify the explanation.
You have your default regular printer, easy for the application to find that one, and then you have a special printer that labels get printed onto. The application needs to know what printer is the label printer. So we allow the user to select that in the
application and the selection is stored in a config file in
C:\ProgramData\mfgr\prog\setting files
I don't have access to the application so I can't change how this works.
In the "regular" world, selecting the label printer driver to use should be per machine, NOT per user. When a new user logs into a machine, the physical printer doesn't go "poof" and a new printer suddenly appear. Same printer for all
users.
Yet in terminal services, the physical machine is "merged" with the virtual machine on the server. And there can be many users logged in at the same time. So each users real machine (and real printer) is injected into the "fake" terminal
services machine. The name of the printers is made unique for each user. So the printers DO go "poof" and change names depending on the user logged into terminal services.
So user "A" logs in and sets up the application to print to "LabelPrinterForUserA" (or whatever the name of the printer happens to be), that setting is stored in the ProgramData subfolder, and all is well. Later, user "B" logs
in, and when they print, the application tries to print to "LabelPrinterForUserA" which doesn't exist for user B or is only accessible by user A. If user B re-configures, that breaks it for user A.
SOLUTION 1: The way that /should/ work (in my mind) is that you define one "generic" printer in Terminal Services... call it "Virtual Label printer" and when the user wants to print to it, the print job gets re-directed back to whatever
physical printer is actually connected to their local workstation. There is a map of virtual printer to actual printer depending on the current user. The application is told once to print to "Virtual Label Printer" for all users.
SOLUTION 2: Or... there should be some way to make the ProgramData sub folders separate per user. E.g. when user "A" tries to access:
C:\ProgramData\mfgr\prog\setting files
they actually get
C:\UserData\UserA\AppData\mfgr\prog\setting files
and user "B" gets
C:\UserData\UserB\AppData\mfgr\prog\setting files
So the question I have is: Does either of those solutions exist hidden somewhere in the setup of terminal server? Or is there another way around this issue that I don't know?

I don't really have a "for sure" answer to this, but because people here can't seem to deal with a question that hasn't been answered I'll provide the best answer I did receive from ServerFault.com user Nathan:
I can feel your pain with using old software on terminal servers ...the solution I've come up with definitely won't scale as it requires some manual configuration, but I've gotten this method to work with our label printers (which require to be
printed to an LPT port...yep, that old).
Share your USB-connected printers to the network on each machine. Then, have the user log in on aunique session for each of them
(a TS account cannot be shared among computers for this to work) and install a network printer pointing to the USB one they shared. Try to use a DNS name to account for possible DHCP movements.
After, it should work. Each user can do this since display names can be identical as long as the ports are different (which they are).
This was clarified by the following series of comments:
I think you are on to something here, and I originally advised the admin to do this. The problem he ran into is that it setup the printer names in the TS as "printer on usersworkstation"
and he could not rename it except to change the "printer" to whatever. E.g. the "on userworkstation" remained. I believe there is another way of installing the printer which avoids this, but I can't find it. Ages ago, one used to do NET
USE LPT2 \\computer\printer password /USER:domain\user /PERSISTENT:YES and then tell the driver to print to LPT2 –  James

@JamesNewton That's actually the exact method we used. The way around the "network printer" part is to install it as local printer and map it to a TCP/IP port that way. –  Nathan

You mean in the case where the printers are TCP/IP connected and not local USB / LPT to the users workstation? That makes sense. Wonder if this will work for USB connected printers... –  James

@JamesNewton You'd share the local printer on the client's PC then on the server connect via TCP/IP to it. You'd need static addresses or use DNS names if DHCP, though. –  Nathan

Ah. Yes. I see. Looks like the LPT thing should work even with a USB connected printer:superuser.com/questions/182655/… –  James

How to provide access to multiple users connected to a Dumb switch? (multi-auth/multi-domain)

Good morning everybody,
I am writing on behalf of not being able to implement a desired outcome in our company network. In fact the situation is as follows:
What I want to do is to be able to authenticate users (802.1x authentication) in our company radius server and authorize them access by having a dynamic VLAN assignment in a multi-user environment on one and the same port of a Cisco 2960 switch. So far, the authentication and authorization has been working completely smoothly (there are no problems with itself). The concept involves the configuration of both DATA and VOICE VLANs as I there is also phone authentication implemented. In order to simulate this environment I introduce a Dumb switch connected to my Cisco 2960 Catalyst.
What I have successfully managed to get to work so far is this:
1) On one switch port I have tried the “authentication host-mode multi-domain” and it worked perfectly for a PC behind a telephone, or with one PC connected to a the dumb switch + the telephone connected to another port of the dumb switch. Logically it is the same situation as there is a separation in two domains – DATA and VOICE. Bellow is an output from show authentication sessions for this scenario.
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
2) On the other hand, when I try the same scenario with the “authentication host-mode multi-auth”, the switch still separates the traffic in two domains and is able to authenticate all users, AS LONG AS they are in the same VLAN.
show authentication sessions:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
However, I cannot succeed authentication of many users from DIFFERENT VLANs, neither in multi-auth nor in multi-domain modes.
What I want to get is an output like this:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
I want the switch to authenticate the users anytime they connect to itself and for them to have an instant access to the network. (I tell this because I tried scenario 1) with multi-domain mode and authentication violation replace, and it worked but, two users never had access to the “Internet” simultaneously!!!
The configuration of the interface connected to the Dumb switch is as follows.
interface FastEthernet0/x
description Connection to DUMBswitch
switchport mode access
switchport voice vlan XXX
switchport port-security maximum 10
switchport port-security
switchport port-security violation protect
authentication host-mode multi-auth
authentication priority dot1x
authentication port-control auto
authentication timer reauthenticate 4000
authentication violation replace
dot1x pae authenticator
dot1x timeout tx-period 10
spanning-tree portfast
The way I see it is explained in the following steps:
- PC1 connects to the Dumb switch. This causes the Cisco switch to authenticate user1. This creates an auth. session with its MAC address linked to a domain DATA.
- When PC2 connects to the Dumb switch, this causes the violation replace which replaces the recent authenticated MAC address with the MAC of PC2. I would like it once authenticated to appear in the authentication sessions with a link to a new DATA domain linked to the VLAN assigned from the RADIUS server.
Is this possible? I think (in theory) this is the only way to provide authenticated access to multiple users connecting through Dumb switch to the network.
Has anybody ever succeeded in such a configuration example and if yes, I would be love to get some help in doing so?
Thank you
Stoimen Hristov

Hi Stoimen,
I have done a setup similar to yours with the only exception being VLAN assignment. When I used dACLs only, it makes things somewhat easier as the VLAN no longer matters. Remember that the switchport is in access mode and will only allow a single VLAN across it (with the exception of the voice VLAN). I think that is the real cause of your problem.
From what I can see, you have 2 options available to you:
1) Use dACLs instead of VLAN assignment. This means that an access list will be downloaded from the radius server straight to the authenticated user's session. I have tested this and it works perfectly. Just Google Cisco IBNS quick reference guide and look for the section that deals with Low Impact mode.
2) Get rid of the dumb switches and use managed switches throughout your network. Dumb switches will always be a point of weakness in your network because they have no intelligence to do advanced security features like port security, 802.1x, DHCP snooping, etc.
Hopefully someone else will chime in with another option.

Simulate Multiple users connecting to same session

Hi All,
Is there anyway we can simulate multiple users connecting to the same session in oracle using PL/SQL.
Thanks,
MK.

As per the architects in our company, lots of users connect to the same session and access the database.Exactly what does this mean? A single session can service one user at a time. I would wager that the architects are envisioning (or describing) a connection pooling setup where the middle tier server maintains a relatively small number of connections to the database (each with its own session most likely) and users operate by getting a connection from the pool, making a request, and returning the connection back to the pool. At any given point, only one user can be using a connection.
If that's the case, you would simulate this by simply executing code in a loop in PL/SQL.
Of course, if this is the case, each connection in the connection pool would its own copy of the collection and so each connection would get its own list of order numbers. You'd have to develop some way to ensure that each session populated its collection with a different set of order numbers.

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting?

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting on the computer, and how?

One possibility is that you may need to "Upgrade" your Cable /DSL Modem if you have an older unit. ISP's that provide your Internet service in recent years have been switching over from DOCSIS 2.1 version Modems to DOCSIS 3.0 version Modems, which handle the new higher data streaming speeds the ISP's are offering. I would suggest you call your ISP's Technical Support and inquire about this possibility.

Internet connection slows down after a while

I have a wrt160n connected to an arris cable modem. When I set it up it works fine - after a period of hours the internet connection slows down a lot. If I then connect my computer directly to the modem it is is fast again. But to get the signal to the router working fast again I have to reset the modem and power cycle the router. Is there a conflict - is my router rationing access or what?

You should download and upgrade/flash your router's firmware...
Download the Firmware from here
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router :
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...
If your Internet Service Providor is Cable follow this link
If your Internet Service Providor is DSL follow this link
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
On the set-up tab change the MTU Size to 1350 and click Save Settings...
For Wireless Settings, please do the following : -
Click on the Wireless tab
- Here select manual configuration...Wireless Network mode should be mixed...
- Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WEP, Encryption should be 64 bit.Leave the passphrase blank, don't type in anything...
Under WEP Key 1 type in any 10 numbers please(numbers only and no letters eg: your 10 digit phone number) and click on save settings...
Please make a note of WEP Key 1 as this is the Security Key for the Wireless Network...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

How to make Adobe acrobat feature to convert SAP Pages to PDF available for multiple users connected to the same server

We have installed Adobe Acrobat X Pro- English,Francais,Deutsch version 10.1.9 in our test environment and tried testing it for converting SAP pages into PDF with a few pilot users. In doing so we faced a challenge, where only one user at a time can use Adobe Acrobat PRO to convert SAP pages in to PDF.As long as the first user who is connected to Adobe Acrobat Pro via SAP isn’t logged off, other users connected to the same server are not being able to get the “Save As” dialog box to save the PDF in their preferred location.
This is a business requirement and we need an urgent solution for the same. Can anyone help us in telling us if this is possible and if yes the how to go about?

It's not something we deal with here, the LiveCycle products are a different world. Key points: Adobe LiveCycle is a range of products, some desktop, some server. LiveCycle PDF Generator is the one you should look at, it comes in 3 editions. License terms are by negotiation. Key management is via its Java API.

How to make Adobe acrobat feature to convert SAP Pages to PDF available for multiple users connected to the same Citrix server

Hi,
In my previous endeavours to solve this business requirement where multiple users will be able to use the Adobe acrobat feature to convert SAP pages inside SAP to PDF, I was told that it is not possible to do this for multiple users at the same time. However I have found an article according to which it says it is possible. Could you check it once and let me know if this article can be used for implementing the requirement stated above as this link clearly indicates that Adobe Acrobat is supported on Citrix.
Please find the link below where it states it is adobe acrobat is supported in Citrix for multiple users.
http://www.adobe.com/devnet-docs/acrobatetk/tools/AdminGuide/citrix.html.

1. What is the Acrobat feature that you mean? There's nothing specific to SAP included with Acrobat.
2. Yes, some Terminal Server configurations appear supported (check carefully). All users of the terminal server will need a license, so far as I know - total licenses = total individual people using.

Multiple users connected to the same server

Hi there,
I was wondering if this scenario would be possible to be implemented on a Snow Leopard Server installed on Mac Mini 2.66:
- one iphone developer that needs to be remotely connected to the server to develop apps
- one project manager that will handle the project files and documentation. He will login to the server and upload/download files
- one app GUI designer that will login from time to time, to make the design in photoshop.
Can these 3 users be logged in the same time on the same server without any lag? Or this version of server will only support one user at a time?
Thank you!

Yes, you can do ssh and terminal connections, but I'm guessing that's not what you want here; I'm guessing you're headed over from X Windows or (more likely) Windows Terminal Services.
Google for Aqua Connect and related for the path that you're headed toward.
In general, Apple Mac OS X and Mac OS X Server runs one seat and one keyboard and one display per station, whether it's an Xserve server or a MacBook or whatever.

Multiple users working using the server from laptops

Hello everyone.
We have a Mac Mini Server in the house, and a couple of Mac laptops.
I know that using screen sharing I can control the server from a laptop. However, when doing this whoever is physically sitting at the server will see their mouse possessed and not be able to do their own thing on the server.
Given the fact that we have multiple users, would it be possible to have multiple people use their laptops to view the desktop of the server as they work on it, while logged in to their own individual user accounts, and control the server independently through those accounts?
Not sure if that description was clear or not, but I think you'll get my gist. Basically I want to use the laptops as thin clients to work using the server. Also key is that multiple people be able to do this at the same time.
Thanks for any suggestions!

The Mac OS X graphical interface is a single-seat design. One Mac, one seat.
There is no analog to Microsoft Windows Terminal Services, nor to multiple sessions on Windows XP Pro or analogous, nor multi-seat X Windows, nor to Thin Clients, with Mac OS X nor Mac OS X Server, short of the add-on package Aqua Connect or analogous.
One of the usual mechanisms for controlling a Mac OS X Server is via the Server Admin tools. These are independent.
Command-level management operations are also available via ssh and analogous. You can ssh into the server and manage many of the aspects of Mac OS X client and Mac OS X Server from the command line. These are fully independent sessions.
Typical Mac OS X Server doesn't require all that much management, and it's probably not the best to have an interactive user operating on a server box regardless. This because servers typically support multiple users, so outages and reboots and operational errors and crashes will effect more than just the user in the seat at the server.

Multiple users accessing the same server.

Ok here is my issue, about 2 months ago I started having issues with Filesharing on my 2012 Mac Mini running Lion server (current update). We have 3 users that VPN into our conpany network and usually access the same folder, 2 months ago they started conflicting with each other. When one VPNs into the network and connects to the server they are fine, if the second one connects to the network they are fine but if the second one tries to access the fileshare they knock the second one off the server. The first one's connection eventually hangs and they have to completely disconnect from the VPN. I am wondering if this was caused by a patch or if there is something else going on. I have tried to reboot the server and checked the logs for anything but I am not seeing what may be causing this. I have restarted the Filesharing in the Server app and still get the same problem, the users are connecting via local credentials to the server. I don't think it is a password issue since either user can log in and access as long as another user doesn't so I am not sure what the issue could be.
any help appriciated,
josh

By 'standard record locking system' do you mean there is nothing I need to do programatically? No block level properties to change?
So you are saying this is just the way it always works. So as soon as one of our call center agents opens a record all I have to do is create a pending update to any field?
But won't another user be able to open the form and just query that record not knowing another user has it open?

Multiple Users Connected to Airport Disk at Same Time

It used to be that I could have multiple user accounts on my MBP connected at the same time to my AirPort Extreme Base Station (802.11n). Now, every time I switch users, I have to reconnect to the AEBS, which in turn seems to disconnect the other user. File Sharing is set up to allow connections via the AEBS password, which always worked fine in the past.
I'm not sure what has changed in my setup, other than installing Snow Leopard (which I don't assume changed anything in this regard).
Any ideas will be most appreciated.

Sorry no one has answered this question. I have the exact problem. I have two user accounts on my MBP. I selected connecting AEBS via AEBS password, too. I can connect with one account and see everything on the disk. When I switch to the other account, it sees the disk but nothing on it. If I disconnect from the disk in that account and then reconnect to the disk, the second account sees everything on the disk. Switching back to the first account, it now can see nothing on the disk and the disk emblem has an icon on it which indicates no access. Clicking on the disk tells me I have no access privileges for the disk. I can then do the same as I did on the second account - use the disconnect button, reconnect, and then all files appear. Of course, when going back to the second account, can no longer access the information. I can do this all day switching back and forth, disconnecting and reconnecting. Obviously, this is not the way it is suppose to work.
I am using snow leopard also.
I have tried setting the disk up by using accounts - created two user accounts and passwords In the Airport Utility application. I can access the disk but nothing shows up on it. I suppose I could have created stuff on it and it would not have been available to the other account. Still, not the way I want to use it. I think I tried using the disk password method also and I think it reacted just like the user account issue or maybe the other---neither will keep both users logged in and have access to whatever is on the disk - which is how I want to use it.
I add this reply in hopes that someone will read both accounts and give us both an answer. OR, if the original poster now has the answer, please provide!!!

WLC-4402 : Users complaint slow down load

Hello
My users complaint the down load speed is slow when using wireless. I checked and indeed is slow.
Before this happen, my WLC is running 802.11b/g. So my thought maybe the 802.11b can slow down
on the users so I changed WLAN to run on 802.11g only. Well, it is still slow. If anyone has any idea
on this is appreciated.
The WLC-4402 is running on version 4.1.185 and all 19 LAPs is 1242AG with IOS version 12.4(3g)JA2

Multiple Instances of Sample Planning App Slowing down Server?

I am trying to work with the sample planning application that came with the installation of EPM system 11. In order to see what effect my changes have in the application and in an attempt to understand the functionality of the Planning, I have created several instances of the sample application so I can have a control instance, and several that I am changing. I currently have created and initialized 4 versions of the Sample Applicaiton, and recently the server is freezing. It will be working fine for about 5 minutes, and then essentially freeze for 10 minutes. Monitoring the Performance on the machine shows that the CPU usage spikes to about 80% during the freeze times, and then drops to below 10%. Does anyone know if having multiple Sample Applications on a single Essbase Server may be causing this problem? Thank you.

I see another thread on this subject. Thanks.
