Maximum number of VPN-connections

Using OSX server how many VPN-connections can be made to a single VPN-server?

Using OSX server how many VPN-connections can be made
to a single VPN-server?
Assuming you're using the unlimited client license version of OS X server, then the number of VPN connections are limited by the number of IP's you specify in the VPN section of server admin.
So if you give 10 IP's to PPTP and 10 to L2TP, then 20 VPN users can connect, 10 of each kind. Additional users should authenticate just fine, but won't get an IP address, and thus will be unable to use the VPN.
Of course, there are processor and bandwidth considerations you should keep in mind as well, which, in most circumstances, will come into play before any IP address limits.
For example, if you're server is on a single T1 (1.5 Mbps) and you've got 10 remote VPN users actively connected, then each one is only going to get ~150 Kbps of bandwidth (and that's assuming nothing else is going in or out of the network).

Maximum number of concurrent connections using java sockets

How can we find out the maximum number of concurrent connections that can be handled by a pooled connection server?
I have a pooled server which creates a predefined number of handlers. Upon receiving a new request it accepts the connection and sends it to one of the handler.
The solution works well for low number of concurrent connections - < 50 or 100
But as the number increases there seems to be an issue
1. Ignoring request even if i increase the handlers
2. Increase in delay. [I feel that the listening thread is not getting the time slice to go read the socket for new requests]
Any idea as to how i can solve this?
Would an NIO socket help [am using the conventional java.io Serversocket, because my clients may not be non-blocking]??
Any help would be appreciated.

There is no set maximum, but it is in the thousands on most platforms. I have a production server that handles tens of thousands of connections simultaneously. Most likely you have a bug in your code.

What is the maximum number of Active Connection in SSG 7206VXR?

Hi,
What is the maximum number of SSG Host or active connection (show ssg service package) for Cisco 7206VXR which running with NPE-G1? The SSG is deploying with Web-login and the TCP-Redirect, Port-bundle and Pass-through is enabling. The SSG is to handling IP session authentication. The SSG is binding Gigabit Ethernet.
The current version of IOS is show as below.

To set the maximum number of services per user, use the ssg maxservice command in global configuration mode. To reset the maximum number of services per user to the default, use the no form of this command. ssg maxservice number and no ssg maxservice

Maximum number of users connections

can any one able to tell me, is there a maximum number of allowable users on the database? And if so, if someone is trying to logon to Connect but the database is at the number of maximum users, what sort of error message will they receive?

Depends on the context of the question. Are you asking about legal (i.e. licensing) limits? Or physical and logical limits of the hardware or software configuration?

Maximum number of socket connections?

Hi there,
I've done a test to check what is the maximum simultanenous socket clients can connect to a socketserver.
The code is as follows:
--------- The Server ------------
import java.net.*;
public class Server {
     public void start() {
          int counter = 0;
          try {
               ServerSocket server = new ServerSocket(9999);
               System.out.println("Server started.");
               while (true) {
                    Socket connection = server.accept();
                    counter++;
                    System.out.println("Client " + counter + " connected.");
     catch (Exception ex) {
     public static void main(String args[]) {
          Server obj = new Server();
          obj.start();
----------- The Client -----------
import java.net.*;
public class Client {
     public static final int NUMBER_OF_CLIENTS = 20; // number of simultaneous connections.
     class ClientThread implements Runnable {
          Thread t;
          int id;
          public ClientThread(int id) {
               t = new Thread(this);
               this.id = id;
               t.start();
          public void run() {
               try {
                    Socket connection = new Socket(InetAddress.getLocalHost(), 9999);
                    System.out.println("Client " + id + " connection OK!");
                    //connection.close();
          catch (Exception ex) {
               System.out.println("Client " + id + " connection Failed!");
     public void start() {
          for (int i = 0; i < NUMBER_OF_CLIENTS; i++)     {
               ClientThread t = new ClientThread(i+1);
     public static void main(String args[]) {
          Client c = new Client();
          c.start();
Test env: Windows XP Sp1
Test results: There is atleast one client which has connection refused.
Questions:
1) Is the situation platform-dependent?
2) Is it possible to configure connection limit on server socket?
Thanks for paying attention.

I've executed 5 times, the 5th one has showed the

A box can only process so much at once. That includes establishing connections.

[Q] Maximum Number of Concurrent Connections to 1142 LAP

We are having random issues of users not being able to connect to our wireless network consistently. The users will have successfully accessed the network previously but then will have difficulty associating to the network. After a period of time, the association appears successful again. My first thoughts were that there was a restriction on the number of clients that could associate to a given AP at any one time.
This is the equipment we have:
1x Cisco Wireless Control Server (WCS) 6.0.181.0
4x Cisco 5508 Wireless LAN Controllers 6.0.196.0
60x Aironet 1142N Lightweight Access Points (LAP)
Is there a hard or recommended maximum number of clients per LAP? If so, where is this defined? From what I have read on these forums, Cisco apparently recommends about 25 clients per AP but I can not find any official documentation to support this.
When I go to WCS Home > General > Top APs by Client Count, the top AP reports 20 clients. However, if I click on the AP Name and go to the Current Associated Clients tab, it is only listing 8 clients - why is this?
Any help greatly appreciated.
Thanks in advance.

1. What error messages do the clients get when they are having association/authentication issues?
There is no error message on the client, it simply fails to connect instantly. On an Android phone, you see it constantly trying to connect, failing and trying to reconnect. After many attempts (at least 10) it may connect successfully. This appears to me that it may be related to aggressive load balancing - here is what I think may be happening:
Client tries to connect to nearest LAP
Nearest LAP has to many clients on associated (as detemrined by the RRM Thresholds > Max Clients setting) and so refuses the connection (and sends a code 17 response)
Client attempts to connect to the next nearest LAP which is also too busy. It too rejects the connection.
Client attempts to connect to the third nearest LAP which is also too busy. It too rejects the connection.
And so on until it comes back to the first nearest LAP
This LAP, which still has too many associated clients, rejects the connection for a second time (its RRM Thresholds > Min Failed Clients is set to 3)
the clients tries the other APs and is also rejected as they are all set to reject connections for 3 times.
Client goes round all the APs for a third time. still getting rejected.
It then attempts a 4th connection to the nearest LAP and is allowed to associated as it is beyong the 3-attempt threshold for rejected connections.
This is my understanding of Aggressive Load balancing and would seem to match the observed behaviour of the clients but I would like to know if this is correct and how I can verify that in the logs?
This goes back to my first question, what is the max recommended number of clients for a 1142N LAP? Furthermore, is there any supporting documentation for this recommendation? Also, if I increase the RRM threshold Max clients to more than its default of 12, will the LAP accept more connections before rejecting them?
I would also like an answer to my second question in the original post.
2. Are you using ACS/RADIUS/TACACS?
We are using 802.1X with ACS for our corporate users on the corporate SSID but the behaviour described above is seen on guest clients that just use web passthrough (i am not sure if it is also on corporate clients, I have not seen any reports to that effect yet).

Maximum number of connections that database can make

Dear All,
I have a problem regarding maximum number of database connections that can be handled .
Theoretically i am aware that the number of sessions we set in init ora settings tells me the maximum
connections that can be opened.but this number will be also be dependent on the capability of the OS to handle the sessions.
is there any way i can analyse the number of possible connections possible if I have the OS memory and CPU parameters with me

Number of User Connections

Is there a way to monitor the maximum number of user connections from Solution Manager?

Hi Ashwin,
By "monitoring" if you mean the checking the configured part, following is the navigation
SOLMAN-->DBACOCKPIT-->Configuration-->Server configuration-->Memory Use-->number of user connections
If you are looking for "dynamic" usage of this parameter,
using DB02-->Performance -->Dash board-->Connections
will give you information of active, free and reuse count values.
Also,sp_monitorconfig "number of user connections"
will give you same results using isql.

E66 - "Maximum number of connections in use. Clos...

When I try to use the web or Google Maps I get an error message: "Maximum number of connections in use. Close an active connection first."
I suspect it's related to having a connection going for automatic email but I did not have this message on my N78 or my 6120 classic. I suspect it's NOT related to my service provider since it works fine with the other phones.
The window that lets you close the active connections only has one to close. It crashes Google Maps pretty hard too.
I've got the e66-2 (NAM version) I don't know if that makes a difference. Any firmware upgrade for the e66-2 yet?
Any workaround ideas?

Solved!
Go to Solution.

Try quitting the active connection and starting a connection on Google Maps first, the next time. This is not abnormal. And are you sure that you used the same provider and were able to do the same thing without closing connections in the other devices ? In my experience, this is network related.

Maximum number of connections in use?! -E71

Hi, I have this problem when I try to connect to the internet through any program. Before you rush to reply, I WANT to have multiple programs using the internet at the same time. I find it completely idiotic having to close Nokia Messaging to open my web browser. I want to be able to run Nimbuzz while running Nokia Messaging (example). Funny thing is, if I select OK when it asks me to close a connection, and then just cancel, everything works ok!! Well, for a while, and then the message pops up again.
Come on Nokia, it's just a simple solution, how hard can it be?
PS. Using E71 with the latest firmware (200)

You can use multiple applications using the internet at any time but ONLY one access point can be in use.
you cant be connected with more then one access point therefore if the different applications is set up to use different access points then you will have the maximum number of connection issues.
Just like the Computer if you are connected to the internet and you connect your phone as a modem the connection from your phone will overwrite the connection and be the default connection.
You may change the settings in the individual applications in the options > settings (may vary from applications)

Nokia N8-00 'maximum number of connections in use'

Hi,
I have creted another APN in the Destinations-Internet settings. Put this APN on priority 1. Then I se internet an it is ok. But when I open Nokia Maps or another App. Sometimes it tries to connect to the old APN then says 'maximum number of connections in use'. Asking me for confirmation to close one connection.
So I move all APN's and Wireless connections out of the Destination Internet. Except for the new on that I want. Still the same message From time to time. How to stop thi message. Deleting an APN is not a solution I am looking for otherwise I would have done that.
Any help is appreciated.

So the on off method I posted earlier did not work. The first APN is still tring to be accessed by some apps after the phone is switched off and on again. The other things I tried..
- Removed the APN restriction and renamed the first APN. When I start the APP it now gives me a warning and lets me choose the APN. I choose the second one so greate. Close the APP. Now when I rename the fisr APN to the original name. APPS try to access it again and I get that original error.
The only thing I could do is configure the first APN name with the actual Access Point of the second APN. This worked All apps are accessing the first APN whaich was reconfigured to look like the new Second APN.
This is not a solution again it is a workaround. Does anyone-else have this problem. Or am I the only one who is configuring multiple APNs. Since my provider has multiple APNs.
I would have thought that this phone supports Multiple PDP contexts, or Secondary PDP context. It was defined in the initial 3GPP specs way back in 2003ish. Nokia can you confirm???
Cheers Peps!
