I am currently trying to understand various security protocol implementation like EAP in wpa_supplicant. But its very complex way by reading wpa-supplicant-devel.pdf from w1.fi.
I want to know from expert in wpa_supplicant how to start in efficient way to deep drive in it. What advance c concept should know to better understand it.
Any resource/material/website/book for this can be suggested.
Please also don't ignore this as descriptive question as you well know that its hard to start in wpa_supplicant.
Thanks in advance.
Run the wpa_supplicant on a Linux machine in verbose mode :wpa_supplicant -Dnl80211 -i wlan0 -c wpa_supplicant.conf -ddd. Use appropriate interface name (-i) and configuration file (-c). To create a simple configuration file please refer this link. With the debug messages from the above command output, browse the source. This provides a starting point to understand various terms in wpa_supplicant security.

Xterm is used when running Corda locally on one computer using gradle.
Is there a way to specify your terminal editor when running as suggested by the following issue?
https://github.com/corda/corda/issues/2605
I completely share your pain on this. The way that runnodes has its tooling baked in makes it impossible for you to customize how the cordform plugin runs the nodes without digging into the internals.
Some other ideas for you
one thing you could do would be to stop using cordform altogether and run your corda network using dockerform (example here: https://github.com/corda/samples-java/blob/master/Features/dockerform-yocordapp/build.gradle#L93) so that the plugin doesn't need to actually create new terminals.
the much harder way would be to actually download the corda gradle plugins (https://github.com/corda/corda-gradle-plugins#installing-locally) and install it locally with your edits to the cordform task so that it opens the terminal of your choice. You may be able to PR them as the cordform task that's usually used to generate the runnodes script comes from here as far as I know.
As a separate note, I saw your github issue and I was disappointed by how that got handled. I'm sorry you had that experience and I'm going to dig into that issue internally to find out what's happening with that.
feel free to reach out to me (David Awad) on slack.corda.net and I can let you know what's going on there.
Thanks as always
I am wondering if it is somehow possible to have an OSGi environment with GoGo shell running with different consoles for input and output.
It is not very handy to write gogo commands into a console where your system is logging a lot of data.
Is there a good solution for that?
There are a number of solutions for your question.
You can use the telnet or ssh interface to gogo. Apache Felix provides both in separate bundles.
Gogo registers a CommandProcessor from which you can make a CommandSession by supplying an Input and Output Stream. It is quite easy to make a small Java Swing program that acts as a shell
Stop logging so much :-)
I am looking for the best way to execute code on a distant machine. Ideally, I am looking for a solution such as Cuda which provides the opportunity to allocate executions on GPU or CPU, but for distinct machine.
I tried distinct ways to do that :
I connect my machines with ssh, export my script, execut it. No particular issue, but not very handy. But maybe this solution could be optimise. Because I open my ssh connection with the terminal, or termius.
I try another way with mosh, same outcomes, but quicker.
Currently, I am working on a Spyder kernel to have a direct link in the place of execution.
I've seen there is also a possibility with a nohup connection, but I have to work on this solution to understand well the possibilities.
Everything works well, but I am looking for a more convenient solution.
Thank you in advance for your answers !
You could either use sshfs along to ssh to mount the remote filesystem on your machine it's easier than always copy the code by hand, if so I would recommend to use screen or something like that that if the connection breaks it offers no problems.
Personal I like to work with Visual Studio Code and the ssh fs extension for this purpose.
An other alternative is to work with X2Go. X2Go enables you to access a graphical desktop of a computer over a low bandwidth (or high bandwidth) connection.
I've researched this feature extensively and need help. PAM is a difficult authentication program for me to thoroughly understand although I'm learning.
We have the option of running either ProFTPD or pure-ftpd on a VPS hosted by hostgator. The OS is CentOS release 5.11. I have complete access to the server. Our goal is to send an email upon successful FTP login by a user. I've successfully used a script which is run by PAM for notification emails dispatched upon successful SSH logins and need to modify it for successful FTP logins. That script which is amazing works fine with ssh (but we need ftp as I've mentioned) and can be viewed here:
http://blog.stalkr.net/2010/11/login-notifications-pamexec-scripting.html
Before I even try to wrap my head around why this script does not work using FTP, despite PAM working on our VPS (for at least ssh), can someone chime in with some theory as to why this is not working at all. I.E., maybe I'm way off base with this idea and it can't work with FTP and PAM in which case I'll just drop this approach. However, when I read configuration settings, etc., on using PAM with these two FTP programs, they seem to indicate this should work.
Additionally, running the following code which is supposed to test for PAM-enabled applications does not return FTP.
ldd /{,usr/}{bin,sbin}/* | grep -B 5 libpam | grep '^/'
Any suggestions or help from gurus would be greatly appreciated.
Found solutions. The answer was to include session_support=YES in the /etc/pam.d/vsftd configuration file. So that's the answer to anyone who may have a similar issue.
I am pretty newbie by this question.
I want to know about possibilities of how to manipulate Jmeter through the console (bash or cmd).
My goal for a start consists in understanding of how to run my testplan.jmx for several URLS. For this I add "server" and "port" parameters into my testplan.
How could I can change these parameters through the console and then run Jmeter ?
Morover, I want to ask you guys to suggest any free online tutorials where I can learn more about "Jmeter in non gui mode" and possibilities for integration Jmeter between different frameworks to use for automated testing.
Thank you very much indeed.
See:
http://jmeter.512774.n5.nabble.com/How-to-Run-Jmeter-in-command-line-td2640725.html
You can launch your test plan from the command line, specifying parameters, like:
jmeter -n -t plan.jmx -Jmy_url=http://www.firsturl.com
Inside your testplan you'd reference that command line param as ${__P(my_url)}
In terms of capturing results when running in non-gui mode, you may want to see:
http://blogs.amd.com/developer/2009/03/31/using-apache-jmeter-in-non-gui-mode/
Personally, my experience is with using the GUI and writing and running test plans that way but this seems workable.
