Limit number of concurrent logins

Hi, Is there a way to limit the number of concurrent logins in Solaris 10 besides writing a script of some form?
thanks in advance,
Ryan

Oops! I just noticed that in the release notes for 3.6(1) the issues appears as being an open caveat. I am going to upgrade to 3.7 and will post the results.

Limit number of concurrent users

Hi everyone,
We'd like to limit to 5 the number of concurrent connections to our dashboard, but we cant make it work.
We've tested changing the Connection Pool, setting to 5 the Maximum connections parameter, but we still can connect with more than 5 users. We've even tried setting the parameter to 1, but still can access the dashboard with more than one user.
Do we have to set any other parameters? Is this the right way of limiting concurrent connections?
Btw, we also tried unchecking "Enable connection pool", but it didnt work neither.
Thanks.
Regards

Limit number of concurrent connection

is there a way for me to limit the number of concurrent
connections to the media server. my upload bandwitdh is about a meg
so having too many connections just kills the whole thing. i would
like to put a limit at 5 connections. is there a way to do
this?

well i am only using flash media server to displaying videos
and just that. the reason i went with media server vs. progressive
was fullscreen method. since flash doesn't natively support
fullscreen you have to open another browser in fullscreen with
javascript. the problem with that is it start loading from
beginning so i decided to go server that way it only has to buffer
and get to the same point without having to load the whole video up
to that point. Now i want to limit number people that can be
watching the video. if i get more that 5 connection the whole thing
slows down. i am not too familiar with server based connections so
i don't know how to limit the number concurrent connections.

Limit Number of active sessions for wlan user in Cisco Prime

Is there a way to limit the number of logins from a particular set of credentials in Cisco Prime 2.1? I want to set a maximum of 2 logins from a particular user on the wlan. I have a guest wlan using layer 3 security and an internal wlan using RADIUS (Windows). Would appreciate the help

There is, but it isn't due to PI. It is a function of the WLC itself.
Under Security, there is a Concurrent User Login, set to 0(which is default) it is unlimited logins. This value can be changed to be the number of concurrent logins that work for your situation.
Be advised, this is not a Per WLAN setting, it is a controller wide setting.

Limit concurrent logins on a WS 2008 environment

Hi all
I'd like to ask if there is any way you can limit concurrent logons on a WS2008 AD domain.
Thing is i want my users (1500+) to only be able to log in on one machine at a time.
I saw a program called LimitLogon.exe but i'm not going to use that because it is unsupported, it requires IIS, it's quite old and it requires a OU structure in AD. I also saw a program called UserLock but we cannot afford that here since we would have to
buy too many licenses.
I was also wondering why this feature isn't in server 2008? It's a quite common problem in many different branches in which IT has been applied (my case, a hospital).
Any help on this?
(I don't mean concurrent logins on remote, i mean just be able to log onto one machine with their account at a time)
Thanks in advance.
Alex

Hi Alex,
As far as I know, there is no build-in feature to limit number of logins of users from many machines in Active Directory Domain. Microsoft has released the LimitLogin
tool. The tool stores logged-on information in a custom AD partition via a Microsoft IIS hosted Web service, a client component, and a logon and logoff script. To run the tool, IIS must be installed along with ASP.NET.
For more information on the tool, please refer to the following link:
Limit Login Attempts With LimitLogin
http://technet.microsoft.com/en-gb/magazine/2005.05.utilityspotlight.aspx
If you do not want to run the tool, there is also ways to only allow users to log into certain machines which can help limit where they are logged into as a workaround.
For example:
1. Go to AD Users and Computers, find the user who you want to restrict, right click and choose Properties, click the Account tab, choose “Log On To”.
Select “This user can log on to:” “The following computers”, then add the computers as you want.
2. Use group policy to restrict some domain users to log on certain computers
Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment
Deny logon locally
If you consider using LimitLogin, you can refer to the following links on how to install and use the tool:

How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file?

How can we send only one message to a WCF service at a time? How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file? Can we do it by Host throttling?

Hi Pawan,
You need to use WCF-Custom adapter and add the ServiceThrottlingBehavior service behavior to a WCF-Custom Locations.
ServiceThrottlingBehavior.MaxConcurrentCalls - Gets or sets a value that specifies the maximum number of messages actively processing across a ServiceHost. The MaxConcurrentCalls property specifies the maximum number of messages actively
processing across a ServiceHost object. Each channel can have one pending message that does not count against the value of MaxConcurrentCalls until WCF begins to process it.
Follow MSDN-

I hope this helps.

Limit the number of concurrent users

Is it possible to limit the number of concurrent users for the application in Websphere or at the http management level?

You don't say what version of Websphere you are using, but here's how you might limit the number of sessions in Websphere 4.0 Advanced Edition (other versions may differ):
Open the Administrative Console. Go down the tree to Nodes, Application Servers and click on the server you want to control (likely Default Server). In the right panel, click on the Services tab. In that panel, click on the Session Manager Service and click the Properties button. That pops up a new dialog.
Select the Advanced tab here. Put a number in the Maximum in-memory Session Count field and uncheck the Allow Overflow checkbox. Click OK, etc, etc, and you'll probably have to restart Websphere.
I said "might" because I don't know if this will do what you want or not. Read the help file associated with that dialog and judge for yourself.

How to limit number of logins per day?

We have a custom web application (WebAS 6.20) used by people and automated systems. Each user has his own login, and some of these automated systems sometimes produce heavy load because they log into system too often.
Is there an easy way to:
1) limit number of logins to, say, 1000 per day and when this limit is reached - do not allow this user to login till midnight
OR
2) dedicate one of the processes to the specific user
thanks in advance

extend PlainDocument class to restrict the number of characters per line.
Set this class as model to TextArea.
Below is a class which does this. May be its useful
import javax.swing.*;
import javax.swing.text.*;
import java.awt.*;
public class FixedNumericDocument extends PlainDocument {
private int maxLength = 9999;
private String max="";
public FixedNumericDocument(int maxLength) {
super();
this.maxLength = maxLength;
//this is where we'll control all input to our document.
//If the text that is being entered passes our criteria, then we'll just call
//super.insertString(...)
public void insertString(int offset, String str, AttributeSet attr)
throws BadLocationException {
if (getLength() + str.length() > maxLength) {
return;
else {
try {
//check if str is numeric only
int value = Integer.parseInt(str);
//if we get here then str contains only numbers
//chk if it is less than 65535 so that it can be inserted
super.insertString(offset, str, attr);
catch(NumberFormatException exp) {
return;
return;

Maximum Number of Concurrent User Sessions Limit?

Please can you tell me if there is a limit for the maximum number of concurrent users sessions that can access the Portal? If so, where is the setting and how do I change it?
By the way, I am not experiencing any issues; I am asking purely for information purposes
Thanks.

There used to be under one of the services in service configuration. I thought it was under portal runtime, but I can´t see it now. It mentioned it in the TZTEP1 course, but I haven´t got it with me.
Having said that, I don´t know if it worked!

Maximum number of concurrent users that can connect to a SQL DB

I see various SQL DB plan S0, S1, S2 and P1, P2 and P3. Each one of them talk about DTU's but never talk about the max number of concurrent users. Where can I find that number and is it configurable by the end user?

It is the maximum connection that is most important. Best practice is not to have users holding on to their connection for long period of time. Maximum user connection in SQL is 32767, resource permitting. Not sure for Azure SQL. If you follow best
practice, you are not supposed to hit this limit cause other limits will be hit first.

Scalability in BlazeDS - What is the maximum number of concurrent users possible with BlazeDS?

Hi all,
is there a limit on the number of concurrent users that can connect via BLAZEDS? I see many places that it is only in 100s and not in 1000s.
is that true? Anybody has doen performance testing on that?
Thanks
Kiran

What is practical? Probably between 1 and 6 streams can be done with reasonable use of bandwidth. However, keep in mind that you will likely want to use the lowest quality setting for cameras so they are demanding the least amount of bandwidth.
Using the Connect 8 numbers, Low quality webcam video with the room at LAN settings should have an aprox average bandwidth consumption of 184 kbps. From there it is just simple math. 6 live streams at that setting will be 1.1 Mbps. Alternatively, at High quality webcam video and with the room at LAN, each stream will average aprox 501 kbps. 6 streams will average 3 Mbps.

BOMM - Metadata manager busobj.exe process limit number of report processed

Hello,
We're facing the following problem, we have a BOMM setup which is running flawless for universes and webi reports. But we have a huge amount (+8000) Deski reports all stored in the same folder.
While the integrator is processing the Deski reports at a certain point in time it goes wrong, we found out that to process the Deski reports BOMM launches a busobj.exe process which uses 2 GB of RAM at the moment the integrator stalls. The integrator does not give an out of memory error, it just stops processing and seems to timeout.
What I am now looking for is a parameter that can limit the number of Deski reports processed by the busobj.exe process, before it is terminated to free up the memory. We thought that the pplimit parameter would do just that, but it is not.
In the log we see all kinds of parameters, but there's very little information about what they do. These are arguments for which we would like to get some more information:
- maxSelect (defaults to 1000000)
- mtc
- ppc (number of concurrent jobs, but this seems not to influence the number of busobj sessions)
- pplimit
- ptc
our setup:
BOE = 3.1 SP2.5
BOMM Version: 12.1.0.6
Kind regards
Guy

Thank you Manoj,
This was already helpful, it confirmed our thoughts about the parameters.
I can not confirm your first comment about the fact that the busobj process closes after eacht report, I've monitored the processing on the server and during the run of the integrator the same busobj process was active (same PID).
Currently we try to process 100 reports at a time by manipulating the date modified on our dev enivronment by checking the reports in scope out and back in, and then starting the integrator.
The reports average around 200KB in size and none of them is set to refresh on open. Base on the logs it takes around 1 minute to process a single report. Depending on the fact if it is processing the associated universes or not. Disk space is not the issue.
I noticed similar behaviour when we used a VBA-script to feed our own mm, and I had to write code to limit the number of reports processed by the busobj process to around 100. I did this by closing the busobj process after 100 reports and then start a new batch of 100 reports in a new busobj process. I think busobj does not cleanup after closing the report, and with every report opened within the same process the memory usage of the process grows, until it reaches 1.8 GB and then the process just hangs.
I can open cases, if you can tell me on how to make sure it reaches you I'll just create one. Do you already have a release date for the fixpack you are talking about?

Hi all,
Does anyone know how to restrict the number of SSH logins of a certain user in Solaris 10? It seems that OpenSSH server doesn't allow to do it.
I know that it's possible in Linux by using PAM.
Can you help me on that?

Max number of concurrent users?

I'm in the process of creating a web site with Cold Fusion and
Oracle. One concern involves the lack of web hosting services
that run Oracle on their servers. So, to get around this
problem, I was considering replicating an Oracle lite database
and putting it on an ISP's server. My thinking is that there
would be little need of DBA functions and I can run it on any
server I choose. But ....
1. Would Oracle 8i lite support a lot of concurrent users?
2. What other factors would I have to consider if I set it up
as a distributed DB ?
Any help on these thoughts would be greatly appreciated.
