Unable to close open and blocked web server ports

I have been running the sun webserver 6.1 as a test development environment on my local pc (Windows 2000) at work. The machine crashed while the web server was running, and while the server instance stopped, the ports being used are still open and apparently, still being used. Restarting my machine does not solve the problem.
Using netstat (through cygwin - i am familiar with linux, and have been using cygwin as the easiest way to do many things with the web server) I can see that the ports are indeed being "used", however i cannot find any running processes (through the top or ps command or the task list) associated with the open ports. Also attempts to start the server again fail, and the server complains that the ports are currently being used.
In order to continue to develop I created a new domain using a different set of ports. Since then, I have (in zealous cleanup) removed the domain that was using those ports, and in attempting to setup a different webserver encountered the open ports.
I need/wish to stop the running processes and close the open ports. Any ideas?
Thanks in anticipation.

There are no such processes running in either the task manager or services.
I do not believe that the domain/web server is running, since the domain instance has since been removed.
However, the ports seems to be stuck on being "used".

Outlook.office365 debug unable to launch the IIS Express Web server 49152

Using office365 portal to test a mail app.
I am using VS2013 and have deployed from VS2013 to my office365 portal.
During the process of starting the debug of the mail app and window pops up stating:
"Unable to launch the IIS Express Web server.
Port '49152' is in use."
Is this error message being given because the portal is refusing the connection or is this from being generated from my PC?

Unable to access Workspace through Apache web server

Hi,
I have configured Hyperion 9.3.1. products in windows.
I am getting the following error message when trying to access Workspace through Apache web server(port 19000). But, able to access through Weblogic Application server(port 45000).
please assist me in resolving this issue.
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

I re-configured the BIPlus components and even now, i am unable to access workspace through Apache web server.
But now, i am getting a different error
Error:

Can anyone help me in resolving this issue.
I have updated httpd.conf and HYSL-Weblogic.conf file in Apache server.

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout).

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout). It is as if the server has decided that the client has timed out during the file upload. The default setting is 30 seconds for AcceptTimeout in the magnus.conf file. This should be ample to get the file across, even increasing this to 2 minutes just produces the same error after 2 minutes. Any help appreciated. Apologies if this is not the correct forum for this, I couldn't see one for iPlanet and Web, many thanks, Kieran.

Hi,
You didnt mention which version of IWS. follow these steps.
(1)Goto Web Server Administration Server, select the server you want to manage.
(2)Select Preference >> Perfomance Tuning.
(3)set HTTP Persistent Connection Timeout to your choice (eg 180 sec for three minutes)
(4) Apply changes and restart the server.
*Setting the timeout to a lower value, however, may prevent the transfer of large files as timeout does not refer to the time that the connection has been idle. For example, if you are using a 2400 baud modem, and the request timeout is set to 180 seconds, then the maximum file size that can be transferred before the connection is closed is 432000 bits (2400 multiplied by 180)

Why do I need to stop and restart web server?????

I am developing servlets on sun's standard web server as well as with Netscape's web server.
The problem is every time I make any changes to servlet and recompile my code, changes are not visible until I stop and restart web server. I guess web server uses cached version of servlet.
Can any body help me to solve this problem? It is matter of some setting issues in web server. But since I am novice, I don't know.........

Some app servers have a "reloadable" attribute that can automatically detect changes in your servlet and reload your application for you. Not sure if all do though... but check through the docs on your app server and see if there's something similar. If not, you're probably stuck manually restarting.

How do I change OS X (10.5.4) web server port?

Hello,
I'm trying to change the OS X web server port from port 80 to something else. In 10.4 I did this via modifying the httpd.config file in /private/etc/httpd/ but this doesn't work in 10.5 — no matter what I set the port to in the config file, it still only connects for port 80 (and yes, I've restarted Apache)?!?
Anyone know how to do this under 10.5?
Thanks,
Kristin.

Unable to close open apps with double clicking the button and when I tap screen does not respond?

Cannot not close open apps with double clicking the button Since downloading iOS8.

What happens when you try? Does double clicking the ?home button bring up the Task Bar of recently used apps? If so what happens when you flick up on the preview screen for the app you want to close?
To quit an app double click the Home button to reveal the row of recently used apps. Flick up on the page preview and it will fly away and disappear. That quits the app.

Replace Quotes, Connection Pooling, and Sun Web Server with MySQL, Oracle

This is code I use to insert data into my MySQL and Oracle databases.
I takes care of quotes and shows use of context, i.e. when you use Sun Web Server's
ConnectionPooling. This code works. Feel free to reply if you have questions on how to set up connection pooling using Sun Web Server 6.1SP - it took quite a long time to learn and I couldn't find much information throughout the web, so I hope this helps...
This is not a question and I am not looking for an answer, but please post comments or suggestions.

This is in one class where I have a hashtable containing the
column name / value pairs that I want to enter into my table.
This class simply creates the SQL string from the values in the
hashtable. It then passes that hashtable including the database
name to a class which executes that sql statement (second code
portion).
/* Insert data into sf_parts. Create the column strings from
 * the provided hash table. Be sure to parse out hash elements which
 * are used for the createTemplate process
 StringBuffer values = new StringBuffer();
 StringBuffer fields = new StringBuffer();
 Enumeration keys = fieldHash.keys();
 while(keys.hasMoreElements()){
 Object currentKey = keys.nextElement();
 String fieldValue = (String) fieldHash.get(currentKey);
 if(values.length() >0){
 values.append(",");
 values.append("'"+fieldValue.replaceAll("'","''")+"'"); // Takes care of quotes and various other special characters!
 if(fields.length() >0){
 fields.append(",");
 fields.append(currentKey);
 sql = "INSERT INTO myTable (" + fields.toString() + ") VALUES (" + values.toString() + ");";
 String insertResult = caq.getInsertDelete(sql,"myDatabaseName"); // your database name is defined in web.xml and sun-web.xml when you use Sun Web Server's Connection Pooling.
 returnValue += " Rows inserted into table(myTable): " + insertResult + " \n";
 And, like I describe above, this method executes the sql statement.
 * Takes care of insert, update and delete requests.
 * Must have set both dbName as well as the sql String.
 * Will return number of rows affected as String.
 * @return String Number of rows affected
 * @exception SQLException
 * @exception Exception
 public String getInsertDelete() {
 checkData(); // this simply checks if the variables dbName and sql are not empty ;-)
 InitialContext initContext = null;
 int rv = 0;
 try{
 // Get connection from configured pool
 initContext = new InitialContext();
 source = (DataSource) initContext.lookup("java:comp/env/jdbc/" + dbName); // I have this set up in web.xml and sun-web.xml (I use Sun Web Server 6.1SP which does connection pooling for me)
 conn = source.getConnection();
 if(conn != null){
 stmt = conn.createStatement();
 rv = stmt.executeUpdate(sql);
 }catch (SQLException e){
 // do something
 }catch (Exception e){
 // do something
 }finally{
 try{
 stmt.close();
 }catch(Exception e){
 // do something
 try{
 conn.close();
 }catch(Exception e){
 // do something
 try{
 initContext.close();
 }catch(Exception e){
 // do something
 return rv+"";
 }

This is not a question and I am not looking for an
answer, but please post comments or suggestions.Using prepared statements would mean that you wouldn't have to worry about quotes.
You should be closing the result set.
You are handling all fields as strings. That won't work with time fields and might not work for numeric fields.
Presumably most of your variables are member variables. They should be local variables because that is the scope of the usage.
You must do something with the exceptions.
Hashtables although convienent mean that problems with usage can only be resolved at run time rather than compile time.

HP LaserJet Pro 200 color MFP M276nw - No Embedded Web Server (Port 80 not even showing open)

The embedded web server on our LaserJet Pro 200 color MFP M276nw is not responding and a port scan of the printer shows that port 80 is not open. We have power cycled the printer and that did not resolve the issue.
Is there a way to check the status of the embedded web server through the control panel on the printer?
Are there any other steps we can take to restore the embedded web server?
Thanks in advance.

Hello csandrews68,
I see you have an LaserJet Pro 200 color MFP M276nw that the Embedded Web Server will not load, port 80 shows as closed.
I suggest restoring the network defaults on the printer:
From the home screen on the printer push Setup (wrench and gear icon)
Go to and select Network Setup
Push Restore Defaults
With defaults restored, connect the printer back to the network and try to load the EWS.
Let me know if that helped.
Thanks,

Can you post the entire log messages here.
Its difficult to understand why it failed. I searched around and found that normally this error message needs to be ignored and its not much of an issue. Also, the error actually means that it is trying to some additional classes which it cant find.
Since you are not being able to deploy your web application, we need to see your entire error log.

Unable to install Sun Java System Web Server 6.1 Service Pack 7 on Wndows

Dear All,
I recently downloaded Sun Java System Web Server 6.1 Service Pack 7 and now I am trying to install it.
The previous version of Web Server 6.1 that i installed is running successfully on Windows 2000 Prof. though it is not meant for it.
To install SP7, i uninstalled the previous Web Server 6.1. I also removed the folder Sun and all the child folders of it. The Sun ONE Web Server services are still available and i can't able to delete them even from registry so i disabled them.
Then I tried to install SP7. But after few steps, it gives error:
You already have a Sun ONE Web Server installed. Install can not proceed.
I am sure that i am able to remove completely the previous instance of webserver as i removed all the entries from registry also and also disabled the services related to it.
Still why i am getting this error?
Will it work on Windows 2000 Professional like its previous version?
If not can i able to install previous version of the Web server 6.1 (without SP7) on Windows 2000 Prof?
Please help me regarding this.
-Sameer

Sameer, you should have uninstalled Web Server 6.1 using the Web Server uninstallation program instead of just deleting its files and directories. Your Windows registry is now in an inconsistent state.
If you can restore your previous Web Server 6.1 installation from a backup, you can run the uninstaller to correctly uninstall it.
If you cannot uninstall Web Server 6.1 using its uninstallation program, you will need to manually delete the Windows services and edit the Windows registry to remove all references to the files you deleted. Note that you can render your computer inoperable by deleting services or modifying the Windows registry. Don't do this if you're not confident with what you're doing.
To delete the services using SC.EXE:C:\>sc delete https-admserv61
C:\>sc delete https-hostname(You can find the hostname for the Web Server 6.1 service(s) using the Services program in the Administrative Tools folder of the Control Panel.)
To clean up the registry, use REGEDIT.EXE to delete HKEY_LOCAL_MACHINE/Software/Sun Microsystems/WebServer.

Hi
As a general rule, whenever you got this kind of message:" This entry already exists in the following tables ", you have no other choice but log a support ticket. It seems as a database inconsistency.

Running the G server and labview web server as a stand-alone serve

Hello,
Now I am running the G web server from the Internet toolkit cooprating with the Labview default web server because I need the server to handle both GCI reguests and the requests of the remote panel.
Now I have a question. Is there any way to make these two servers as stand-alone applications and also make it to be window service ( I think if I could make them the stand-alone applications, making them to be window services would be easy)? I just want the web server to be a stand-alone application without installing the Labview (just installing the run-time engine) on one machine. Could this be done? Thank you very much.
Best Regards,
Benjamin Chu

Hello Benjamin,
for running a LabVIEW application as Windows Service is here a tutorial.
I formerly tried to get the G web Server into an application and I know there were some dynamic VIs loaded by the HTTP Server Control.vi and some SubVIs. I never tried this seriously enough to get it running.
You need at least to put the VIs vi.lib\addons\internet\http\http0.llb\HTTP Server, vi.lib\addons\internet\http\http0.llb\srvr_%02d.vi (%02d is part of a format into string with a for loop index), HTTP Load Configuration Files.vi as dynamic VIs into your build definition.
Running the G Web Server and looking at the VI hierarchy is not for help because for some reasons the G Web Server VIs will not show up in the VI hierarchy window.
