JMeter (Active?) FTP to VLTrader - ftp

Situation:
I'm using JMeter to load test my communications application (Cleo VLTrader). I'm new to JMeter, and have been able to get HTTP communication working, but not FTP. When I attempt to use a JMeter FTP Request sampler, I can see on the server side that the JMeter is issuing a "PASV" command, and failing shortly thereafter due to a "502 PASV command not available" error.
Question:
How do I need to configure my JMeter FTP Request sampler to connect to my FTP server?

1. Sorry for this but just to ensure: have you ensured that FTP connection succeeds manually, i.e. not from FTP Request in jmeter script but via console/telnet connection or any FTP client utility?
2. FTP Passive mode
Possible cause:
Since your FTP Request fails during PASV command execution can suppose that the root cause is that your ftp server doesn't support passive mode while jmeter's FTP Request uses passive mode by default.
To ensure this try to switch into Passive mode after connecting to your ftp from console,
e.g.
telnet your.ftp.server.url 21
USER yourusername
PASS yourpassword
PASV
or
ftp -d your.ftp.server.url
USER yourusername
PASS yourpassword
passive
or using any ftp client utility which have option to select mode (active/passive) for connection.
If the same issue appears during this - well, the problem is that your ftp server doesn't support passive mode which is used by FTP Request.
See e.g. this for explanation of differences in both the modes.
Possible solution:
As per jmeter sources:
ftp.enterLocalPassiveMode();
switch to passive mode is used by default and there is no possibility to set mode externally in FTP Request configuration screen.
But you can implement ftp request yourself, avoiding usage of FTP Request.
You can use FTPClient realization from Apache Commons Net and script ftp connection in BeanShell Sampler.
Very simplified this may look like:
import org.apache.commons.net.ftp.*;
FTPClient client = new FTPClient();
client.setDataTimeout(3600000);
client.connect(ftpHost,ftpPort);
client.login(userName, userName);
client.setFileType(FTPClient.BINARY_FILE_TYPE);
...
// FTPClient uses 'active mode' by default
if (ftp_passive_mode) {
client.enterLocalPassiveMode();
} else {
client.enterLocalActiveMode();
}
...
client.logout();
client.disconnect();
Maybe also I'm wrong and the reason of your issue hides in another place.
Hope this will help you to diagnose and solve your problem.

Transfer Files through FTP in Windows Batch Scripts having Private Key

I am using these command to transfer a file to an SFTP location.It has an private key(Puttygen) with
passphrase.
open ftp://%1%:%2%#%3%/ -explicittls -certificate="32:4b:5e:a7:05:b9:e4:2d:7d:44:cb:c1:0e:ee:0e:17"-privatekey=D:\SSIS_DEV\DBTeam\Transfer\Rural\Private.ppk
put %4%
I am getting a timeout error while connecting.
exit
You want to use SFTP, but use FTP (ftp://) protocol in the session URL.
Use sftp:// instead:
open sftp://%1%:%2%#%3%/
FTP and SFTP are two completely different and incompatible protocols. You get the timeout, because you are trying to connect to the FTP port, which the server does not listen on.

Unable to Retrieve Directory Using ProFTPD(WHM)

Well, after looking for many solutions. I came here now.
I am setting up WHM/cPanel for hosting website. Everything was going smooth but I am stuck on FTP connection (Server sent passive reply with unroutable address. Using server address instead.)
Server Details:
CentOS Linux release 7.2.1511 (Core)
WHM/cPanel Version 11.58.0.13
FTP Server: PureFTPD
Acutal error while connecting
To fix this issue and get FTP working you need to open up more numbered ports so FTP can connect. I assume you are using CSF.
Login to WHM then go to CSF >> Firewall Configuration >>
allow TCP_In 30000:50000 and TCP_Out 30000:50000
Once you made the changes Restart the firewall
Now you need to make changes in FTP config file to use these ports, you will find this file to this location /etc/pure-ftpd.conf
Now you will see a line as follows and you will need to uncomment it
# Port range for passive connections replies. - for firewalling.
PassivePortRange 30000 50000
Restart FTP Service and should work.

FTP upload in passive mode not working, It opens data connection and times out with "Data channel timed out."

The above is the FTP done using command-line. When I check with FTP client there is a file with 0 size created.
There's a firewall or NAT between the client and the server that prevents a connection to the port 51638 (= 201 * 2^8 + 182).
If you are not able to transfer files to/from the server from anywhere/any other FTP client, the server was most likely not set up correctly. Particularly the Windows server firewall was not configured with a rule for a data port range. Another option is that the server is not aware of its external IP address. That would be the case, if the part you obfuscated (*,*,*,*) is not the same IP address you connected to.
See my article on FTP Connection Modes for explanation of the network issues with FTP data connection.
And particularly see my article on configuring IIS FTP Server for instructions on configuring the firewall and/or the external IP address.

Downloading a file from FTP using kettle

I was trying to download a file form FTP server(Remote machine) using pentaho kettle (Get a file with FTP), I can able to do that in my local machine. But when i try to deploy the app in jboss web server it fails to download resulting in a error "Error getting files from FTP : Login incorrect."
But everything seems to be correct regarding the login details.
Did i have configure any where else in the server? Please help.
There are several things you could check in this case:
Check that the security settings of the remote FTP server allows for the machine that runs the job to establish an FTP connection. If you have access to the server, try the following command to ensure that the server has access:
telnet <your-remote-ftp-server-host> 21
# Or try:
telnet <your-remote-ftp-server-host> 22
Verify that the remote FTP server respects FTP connection requests, otherwise try SFTP (Get a file with FTP & Get a file with SFTP are two entirely different job steps in Kettle)
Wherever you are fetching your FTP credentials from (ideally a configuration file), test that the credentials are properly read by the job in the relevant scope - use the Write To Log step for that matter

Ruby NET::FTP Not Resolving Correct IP

I am trying to connect to an FTP server using:
ftp = Net::FTPFXPTLS.new
ftp.passive=true
ftp.debug_mode=true
ftp.connect('200.111.111.11',21)
ftp.login('Username','Pass')
ftp.chdir('inbound')
ftp.putbinaryfile("./#{filename}", "/#{filename}")
ftp.close()
For the purposes of this example 200.111.111.11 is the correct IP and 10.1.1.1 is the fake IP.
When I connect via an FTP client such as Transmit I connect fine and everything works as normal but in the transcript it states:
Cmd: PASV
227: Entering Passive Mode (10,1,1,1,47,79).
Fixing bogus PASV data address from 10.1.1.1:12111 to 200.111.111.11:12111.
Then when it tries to connect via the ruby script:
get: 425 Failed to establish connection.
When it tries to do any action like LIST or STOR because the PASV command always returns 10.1.1.1:12111.
So is there anyway to ensure the PASV command uses 200.111.111.11 and not what is sent back to it?
This seems to be more of an issue with the gem, there is a solution for it but woud take a little while to implement. In order to save time we simply switched the protocol to use SFTP which works flawlessly. (Switched both server and code)
