"How to record a script in Jmeter using VPN server" - jmeter-5.0

I'm new in JMeter and I am using the JMeter5.1 and I want to know about that how to record the script in JMeter through VPN Server?
I want to record the script in using this command line:-jmeter.bat -H -P -u -a -N
But I'm facing a some issue.That website run only Firefox browser without proxy. that's why I'm not able to record the script.

I know you can do this but there is no enough information in your question. Can you give more details so the other can try to help!
What is your situation? Are you tying to record an application on the same network as JMeter or a different network...?
My only experience with using VPN was when I had to record via VPN few times using a work laptop from a hotel room. I was able to do so, but I got few weird issues about JMeter browser trust certification, so I had to remove it and re-install it again.

"UnknownHostException" in Jmeter

I just started learning JMeter today. Wrote a simple web test - 10 user, 1 iteration to hit a webpage,
but in the "view result tree" I get "JMeter Response code: Non HTTP response code: java.net.UnknownHostException"
Thanks in advance for helpers
Most probably you're behind a corporate proxy, your computer is not connected directly to the Internet, it is connected via special machine which grants Internet access to other computers over the network.
You need to make JMeter aware of this proxy, it can be specified at
"Advanced" tab of the HTTP Request sampler (or even better HTTP Request Defaults)
Via command-line arguments like:
jmeter -H your-proxy-host -P your-proxy-port
Via system.properties file like:
https.proxyHost=your-proxy-host
https.proxyPort=your-proxy-port
More information: Using JMeter behind a proxy
You might give a try using Chrome Plugin of Blazemeter.
Add Blazemeter Plugin to Chrome (You need to create free account on Blazemeter)
Record sample script
Download Script as .JMX
Try executing the script from your local version of JMeter
This helps with automatically recording browser proxies.

JMeter recording - 'ERR_SSL_PROTOCOL_ERROR' and 'Software caused connection abort: socket write error'

I'm new in JMeter and my topic seems to be very similar to another ones already existing. However, it is not - I was trying already all the solutions for the errors that I get and nothing works :/
I have already set up all proxy settings and certificates, and it's working fine (with the same settings) on the other VM.
Outside the recording, I can see proper 'No Internet' warning:
enter image description here
However, once started recording, there are errors in the console and the front end of the application does not look like originally:
enter image description here
Please help! I've already done all the recommendations for clearing caches, SSL, removing files in Windows32 archive and so on...
You should try recording your script using Blazemeter Chrome Extension. Hope, this resolve your issue.
It might be the case there are differences in machines themselves, not in JMeter settings, for example this No Internet message most probably means that the browser is connected to JMeter's proxy server, but JMeter itself cannot connect to the internet.
Try creating a simple manual Test Plan with a single HTTP Request sampler to open http://example.com website. If the request will be successful - you will need to double check your browser and JMeter configuration. However if you get the UnknownHostException instead it may mean that:
Networking configuration of the machine is incorrect (it cannot access the Internet)
The machine requires an upstream Proxy server in order to be able to access Internet resources so you will need to make JMeter aware of this proxy server by passing appropriate command line arguments to the JMeter startup script:
jmeter -E https -H my.proxy.server -P 8000 -u username -a password -N localhost
in order to make the changes permanent you can define:
http.proxyScheme
http.proxyHost
http.proxyPort
https.proxyHost
https.proxyPort
in system.properties file and http.proxyDomain in user.properties file, check out Apache JMeter Properties Customization Guide for more information on JMeter properties and ways of setting and overriding them

How do I record test script of web application on localhost in Jmeter?

I am trying to record the flow of my web application using Jmeter 5.1.1 templates in Mozilla Firefox, but it does not record flow for the web application. But when I test any application online then it works fine.
I could able to solve this issue by following steps:
Use IPv4 addressinstead of using localhost or 127.0.0.1 to access your local application. (you can get IPv4 address by opening command prompt and typing ipconfig)
Get JMeter's recording template from File > Template.
Set proxy on 8888 port and start recording.
Thank you !!! I hope this helps
Try to record your scenario with BlazeMeter Plugin, you just have to sign up which is free and then you can learn how to record your script by referring Record Jmeter script Using Blazemeter Plugin

JMeter HTTP Proxy server is not recording

We are trying to do performance testing using JMeter.
I used the sample guide provided in jmeter using HTTP PROXY SERVER but my record controller was not recording any requests.
After doing a lot of research and here is what the complete scenario is.
I am accessing external sites using company proxy server. So, after a bit of research, I understand I need to start my jmeter by supplying all information via command line. e.g.
jmeter -H 129.198.1.1 -P 8000 -u someusername -a someuserpassword -N localhost
Now i understand that, i don't need to confuse these settings. By default JMETER uses its own internal proxy server.
We need to configure our browser so that it uses jmeter proxy settings and i did that way.
I added a thread group, a recording controller, http proxy server with url include patterns and exclude patterns but still, it's not able to record any scripts.
What am i doing wrong? Can someone help me with it?
I used document JMeter proxy step by step which comes bundled with JMETER documentation.
Here is my configuration
Remove everything in :
URLs patterns to include
URLs patterns to exclude
click on Add suggested excludes
It should work.
Currently your include patterns are wrong :
https://jmeter.apache.org/usermanual/component_reference.html#HTTP_Proxy_Server
The include and exclude patterns are treated as regular expressions (using Jakarta ORO). They will be matched against the host name, port (actual or implied) path and query (if any) of each browser request. If the URL you are browsing is
"http://jmeter.apache.org/jmeter/index.html?username=xxxx" ,
then the regular expression will be tested against the string:
"jmeter.apache.org:80/jmeter/index.html?username=xxxx" .
Thus, if you want to include all .html files, your regular expression might look like:
"..html(\?.)?" - or ".*.html" if you know that there is no query string or you only want html pages without query strings.
See this reference documentation for how to record:
https://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.html

I had a similar problem when configuring firefox for proxy and recording on localhost. In Firefox -> Tools -> options -> Advanced -> Network -> Settings
there was an entry for localhost in No Proxy for.
I removed that and it works
I have faced similar problem, please see below. As JMETER proxy is running on localhost, please uncheck the below checkbox.
Install Jmeter Chrome extension which records HTTPS protocol without any issue.
You have done wrong writing the syntax/format for "URL Patterns to Include" and "URL Patterns to Exclude" in "HTTP Proxy Server" under Workbench. The syntax/format should be as below:
.*\.jsp
.*\.jsf
.*\.html
But, you have written forward slash(/). Such as .*/.jsp. After correcting the syntax it should be recorded.
The Jmeter proxy server must be started before Firefox can connect to it. JMeter has its own proxy server so the Recording Controller 'start' button has to be pushed before FF will allow access to a website.
As far as I can understand the issue. The issue is not what it seems, JMeter and Browser are able to interact with each other. But the thing is that How to make sure that JMeter is able to use the proxy.
Now for this, there are many way outs. I'll start with the easiest one.
Install Blazemeter Extension in your browser and start recording in it. It will provide you a .jmx file once you're done
The second one is configuring JMeter to access the proxy.
the command is changed a bit now.
jmeter -E https -H my.proxy.server -P 8000 -u username -a password -N localhost
Please note that you need to change the below values:
my.proxy.server
8000
username
password
In case you don't use a username and password to connect to the proxy, simply omit the -u username -a password part.
Reference: https://jmeter.apache.org/usermanual/get-started.html#proxy_server
This will work to record the script.
Now, to run the script. This may not execute the things as expected.
In that case, you have a Advanced Tab in HTTP Request Sampler, go there and provide your proxy server details there.

Speeding up ssh in batch files

This is my situation:
I have a linux server/media center with a windows client.
My goal is to remote control rhythmbox amongst other things.
I've done this using plink (windows based cli ssh toy).
The problem is that starting up an ssh session logging in and sending a command is understandably slow as hell. When I had a windows server I used a tool called psexec which was almost instantaneous.
Is there any way to speed this process up? Either somehow sending the commands with the login request which should show some improvement. Or by maintaining a persistent ssh connection which I can use. (plink dcs at the end of the command).
More info: On my windows machine I'm using a bat like:
plink -ssh -l username -pw pass myipaddress "/home/username/bin/skip"
On my linux machine the skip bash file is something like:
//needed to get around a x11 error caused by controlling rhythmbox over sshif its an ssh connection copy the dbusaddressfirhythmbox-client --next //the cli wrapper for rhythmbox
Further Research:
The only way to go seems to keep an ssh connection open/maintained as a service. This seems doable as there is a demand due to setting up ssh tunnels (to bypass firewalls). From there I'd need a way to send the command line commands to this existing connection or reuse that connection.
The other option is of course to NOT use ssh. Hell I already have a connection through samba file shares and there is no lag there. I bet I could put a service linux side that checks for a modified file. Then have an ap client side that modifies said file. Amazingly hacky but so far it seems like the best option. And by best I mean the only one that cuts control lag. There has got to be a better way than this, I can't be the only nerd using linux as a media-center that wants remote controls. This kind of moves the topic from stackoverflow to superuser but that's ok.
You could user an SSL certificate to get rid of the login part. Alternatively, build yourself a small HTTP server which uses an "exotic" port for controlling your media player (amarok, btw, has one build-in)
Switching to something like mpd will bypass the ssh issue, although I give no guarantee that changing tracks will be any faster.
If anyone is curious, I ended up implementing an http based server with php to execute commands server side. And client side I used curl.exe to allow me to have nice click-able buttons without the overhead of a web-browser.
Also nice since it allowed me to implement an in browser UI which is great to use from any machine with internet, ones that don't have ssh installed. And works wonderfully from my phone as a remote control (which I can use from a country away if I so chose...)
