Jmeter: FTP Request Sampler: " java.net.UnknownHostException" - ftp

I am working on FTP Sampler and connecting with Public FTP Server
"ftp.swfwmd.state.fl.us" for "Get" method.
But JMeter is showing following error in LOG:
Response code: 000 Response message: java.net.UnknownHostException:
ftp.swfwmd.state.fl.us
Please help me out in this problem.

The message indicate host is not known from your machine.
So check your DNS or add manually an entry in your DNS.

Try accessing the server using IP address instead of hostname - 204.76.241.31
If point 1 doesn't help most probably you are sitting behind corporate firewall. For HTTP-based samplers you can specify proxy server details by adding the next lines to system.properties file (lives in "bin" folder of your JMeter installation)
ftp.proxyHost=hostname or IP address of your proxy
ftp.proxyPort=port of your proxy server
if above doesn't help you can try setting the following properties instead:
socksProxyHost=hostname or IP address of your proxy
socksProxyPort=port of your proxy server (normally 1080)
JMeter restart will be required to pick the properties up

How to Change IP address of [ ::1 ] in JMeter

I am trying to Recode the test Script of VPN accessed Website and for that i am using JMeter HTTP(S) Test Script Recorder and start connection by using the localhost but by analysis i monitor that JMeter send request and in Remote server section it send [::1]:Port this value so please help me how to change this method and share Remote IP in Remote Address section
If you want to switch JMeter to use IPv4 localhost loopback address - 127.0.0.1 you need to add the next line to system.properties file:
java.net.preferIPv4Stack=true
More information:
Java Networking Properties
Apache JMeter Properties Customization Guide
You will also need to configure the browser to not to bypass proxy for local addresses, i.e. for Firefox you need to set network.proxy.allow_hijacking_localhost option to true

jmeter and unknown host exception

Please guide me what all are the settings needs to be done in jmeter while recording an https request through jmeter. I am getting unknown host exception while doing the same.
Thanks
Assumption 1: you have misconfigured JMeter and/or browser. You can get JMeter configured for recording in a couple of clicks using Templates feature.
From JMeter's main menu select File -> Templates -> Recording -> Create
Configure your browser to use the following proxy:
Proxy host: hostname or IP address where JMeter is running
Proxy port: 8888
Use proxy for all protocols (if available) - check
Bypass proxy for local addresses (or equivalent) - uncheck
Assumption 2: you (or your company) are using corporate proxy to access Internet and/or intranet. In that case you need to pass proxy details to JMeter startup script like:
jmeter -H proxy_host -P proxy_port ...
See Using JMeter behind a proxy guide for more information on the domain.
You can also consider an alternative solution which allows recording JMeter test right from browser without having to configure proxies, worry about SSL certificates, etc. Check out JMeter Chrome Extension
For unknown host exception, you should add the domain name and ip address pair in hosts file. For windows, this file is present at C:\Windows\System32\driver\etc\.
For example:
102.54.94.97 rhino.acme.com
For recording HTTP requests through JMeter, you have to configure some elements in your system. Steps are :
1.Add thread to test plan.
2.Add recording controller to plan
3.Add Http Proxy Server to Work Bench
4.address 127.0.0.1 port is 8888
5.Start proxy server
6.go on the recording when finished stop proxy server.
You have to configure your browser setting or install Certificates to record through JMeter. For step by step JMeter Proxy setting follow this PDF Step by step JMeter HTTP(S) Test Script Recorder Configuration

jMeter on VM with no internet not finishing test

My company is trying to use JMeter in a VM (Windows Server 2003 :( )with no internet connectivity to hit another VM with a server set up and code running on IIS. I set up the ip address in my hosts file, let's call it server.dev for now. Our goal is to hit server.dev/doSomething When we go into IE and hit server.dev we get a response.
We use a keystore with JMeter and it says that it creates it correctly. In JMeter we have an HTTP Request where we hit the server.dev, and the path is set to /doSomething. JMeter then starts, and the log has no errors, but once it says "Creating the HTTPS Trusall Scheme" it hangs. When I put debug flags on it shows that it created the SOAP Request correctly and seems to send it out. The Headers should all be correct. It hangs here for about 1 minute and then shuts down with error with saying something along the lines of "Could not get response from server".
Does anyone have any ideas on where to go from here? I tried to debug for hours, but got nowhere. I can't seem to load up Fiddler to see the network traffic either, since there is no localhost set up.
Most likely that IE uses proxy and JMeter does not. Try other browser, i.e. Firefox (it doesn't respect system proxy settings if you won't import anything during installation) and if Firefox won't be able to establish the connection - my assumption is correct and you're sitting behind the proxy server.
There is a way to "tell" JMeter to use a proxy server, it is controllable via command-line arguments, to wit:
-H [proxy server hostname or ip address]
-P [proxy server port]
-N [nonproxy hosts] (e.g. *.apache.org|localhost)
-u [username for proxy authentication - if required]
-a [password for proxy authentication - if required]
See Using JMeter behind a proxy guide for details and Full list of command-line options for the full list.
You can also configure proxy settings in system.properties file (which lives under /bin folder of your JMeter installation), add the following lines to it:
http.proxyHost=your.proxy.ip.address.or.host.name
http.proxyPort=your.proxy.port
https.proxyHost=your.proxy.ip.address.or.host.name
https.proxyPort=your.proxy.port
And after JMeter restart everything should work as expected.
See Apache JMeter Properties Customization Guide for more information on JMeter properties and ways of setting and overriding them

how to record in jmeter when proxy settings is configured to connect to internet

To record scripts in Jmeter we need to run the proxy in local port 8080, where as in browser I need to configure for internet connectivity proxy to connect to internet.
The company I work for is providing me internet through a proxy server.
Any one who knows how to record script using Jmeter while there is already internet proxy set up in the browser to connect to internet.
Thank you
I believe that your company uses PAC file to connect to the internet. JMeter will not execute PAC file. Refer JMeter is not a browser. PAC file has javascript which will not execute by JMeter.
Using browser developer tools or by asking your Network Admin or IT support team, you can get which IP being used by your company to connect to the internet.
Once you got the IP address, you can follow the steps mentioned by George in this thread to record/reply successfully.
You can provide the proxy server settings by running JMeter from command line like that:
jmeter -H [proxy server hostname or ip address]
-P [proxy server port]
-u[username for proxy authentication - if required]
-a [password for proxy authentication - if required]
Then you should set localhost and the port specified in HTTP(S) Test Script Recorder as the proxy address and port in your browser.

Jmeter's proxy server does not record

New to JMeter. I have downloaded and configured proxy server as the step by step guide from JMeter website. Got right log message such as "protocol 8080 has been created" and "Proxy is up running" etc. But it just did not record localhost:8080 with Tomcat. Change to Neoload to record localhost:8080 and everything works fine but JMeter just does not record anything. There is no errors in the log or within the screen.
Did you start the proxy ?
Try stopping it to see if you get an error in browser.
Are you sure neoload is not already listening to this same port and jmeter could not start on this same one.
Finally you could try using your ip in browser address.
I don't know what mistake have you made. This is what you can do from scratch:
Create empty plan
Add HTTP Proxy Server to WorkBench
In its configuration set port to free one at your computer (maybe 8080 is busy). Click Start
Set browser proxy to localhost, choose the same port as in JMeter's proxy
Browse to any url
--> Samplers should appear in JMeter
You may also like to change Target Controller so samplers will appear in more appropriate place
