I am using an Ubuntu 20.04 machine along with the CLion IDE 2020.3.2 and I want to create an app using WolfSSL which would need the TLS1.3 implementation of it.
Using CLion, I cloned the official repository https://github.com/wolfSSL/wolfssl.git. CLion automatically built the project and I was able to run all the \wolfssl\examples perfectly.
Thus, the resumption session does not work.
I run both Server/Client with these arguments: client/server -v 4 -r
And I am getting this output from the client side: didn't reuse session id!!! which I can verify from Wireshark that there was no resumption made but just another handshake.
At another build I did, where instead of cmake ( which is the default of CLion ) I used make I manged to run properly the resumption but for that I had to add in the configuration before the build this command: ./configure --enable-all which "Enables all wolfSSL features, excluding SSL v3".
What is the equivalent command of --enable-all I should use in my Cmake configuration ? Or what should I do so I can achieve properly the resumption?
I tried -DWOLFSSL_ALL -DENABLE_ALL and others but did not managed to do it. I tried including many of them separately to find which is the one that enables the resumption but nothing yet.
The specific wolfSSL option for enabling TLS sessions is HAVE_SESSION_TICKET.
There is not currently an equivalent macro for the ./configure --enable-all option, but you can use the "user_settings" method to get close:
https://github.com/wolfSSL/wolfssl/tree/master/examples/configs
Here is an example that configures most of the library options:

When trying to install Phantomjs on Ubuntu 22.04, I get the following error:

I had the same issue and fixed it by setting export OPENSSL_CONF=/dev/null prior to phantomJS usage. If it's not possible for you to disable openssl then you would have to pack you application with older OpenSSL version.
Explanation:
Ubuntu 22.04 uses the new OpenSSL version 3.0.2 instead of the older OpenSSL version 1.1.1 . These OpenSSL versions are not fully compatible, so this is why you see this error when PhantomJS tries to auto configure the SSL/TLS settings.
Above answer is little about as I am describing.
Step:1 First stop your node server then run this command in base directory.
Step:2 I suggest you to comment out the lines providers = provider_sectin in the
file/etc/ssl/openssl.cnf
Step:3 Start your application

The tested platform is windows using cygwin. I download bonmin-1.8.8 from https://www.coin-or.org/download/source/Bonmin/.
First, I obtained the third party code with the commands
./get.asl
./get.blas
./get.lapack
./get.mumps
then ran the command
./configure -C
and it shows that the configuration of bonmin is successful.
But then, when I run
make
There's something wrong with the makefile of Mumps.
It shows a rank mismatch between the actual arguments at (1) and (2)
MUMPS/src/dmumps_comm_buffer.F:2670:23:
I want to know how can I successfully make it?
I'm new to Elm. and I'm not good at English. So, if any ambiguous or wrong thing is there, please let me correct it.
----------- edit -----------
All my problem below is on WSL. when I'm trying on windows, all work fine. then... why elm install doesn't work on WSL? did you have any idea?
-------- problem --------
when I try to elm-test init, it doesn't work like below
$ elm-test init
Here is my plan:
Add:
elm/random 1.0.0
elm-explorations/test 1.2.2
Would you like me to update your elm.json accordingly? [Y/n]:
-- PROBLEM DOWNLOADING PACKAGE -------------------------------------------------
I was trying to download the source code for elm/random 1.0.0, so I tried to
fetch:
https://github.com/elm/random/zipball/1.0.0/
But my HTTP library is giving me the following error message:
ConnectionTimeout
Are you somewhere with a slow internet connection? Or no internet? Does the link
I am trying to fetch work in your browser? Maybe the site is down? Does your
internet connection have a firewall that blocks certain domains? It is usually
something like that!
but my Browser(Chrome) is working beautifully, and even in WSL (the environment that I run elm-test init command at) is too.
$ curl https://github.com/elm/random/zipball/1.0.0/
https://codeload.github.com/elm/random/legacy.zip/1.0.0<body>You are being redirected.</body></html>
then I also try again to redirect the URL
$ curl https://codeload.github.com/elm/random/legacy.zip

I think there's no Network Problem. My PC can connect with the repo, and I think it will be downloaded well.
I lastly tried just elm install, and that throws the same error too. it seems like Elm can't connect with the repo, even if My PC can.
$ elm install elm/random
Here is my plan:
Add:
elm/random 1.0.0

I recently had reason to use WSL for elm development. It wasn't much fun and I'm glad to be back on Mac! What I found was that certain disk operations on WSL seemed to go very slowly and that could lead a variety of weird issues.
I was using Webstorm, which does not handle WSL well, so in the end I did everything on C: drive (rather than in /home/...) so that webstorm could run the windows version of elm-format, while my node development environment was run on the linux layer.
That's not a precise answer to your question but just to say that it can be done, but its not an ideal way to write Elm code in my experience
I had same issue and it was solved.
It was due to DNS server settings.
Create a file /etc/resolv.conf and write the following line.
nameserver 8.8.8.8
Then WSL will refer to Google Public DNS and works fine.
However, when restart WSL, the settings revert back.
Therefore, the following settings are also required.
Create a file /etc/wsl.conf and write the following line.
[network]
generateResolvConf = false
wsl --shutdown and restart WSL.

I am trying to diagnose a few issues with ssl connectivity with Leingen. I am trying to find what SSL Key Store and Trust Store is being Used by Leingen,
I am behind a corporate firewall and we have self signed certificates deployed on all our desktops . I am running lein.bat on a windows 10.
Hence I have to start Leingen with java -Djavax.net.debug=true option.
The :jvm-opts in the project.clj wont work -- I need to make sure the Liengen's JVM is started with this option
You can set leiningen JVM options by setting LEIN_JVM_OPTS environment variable before running lein in the same terminal session.
The lein command is just a shell script which eventually invokes java with various options. You can edit this script to see what options are used and/or to modify them.
As Piotrek mentioned, the LEIN_JVM_OPTS environment variable is the canonical way of passing options to the jvm in which lein runs. You can see it used on line 372 of the source code.
For your case:
> export LEIN_JVM_OPTS='-Djavax.net.debug=true'
> lein clean
> lein run
Since you're running windows, you'll want to actually look at the lein.bat file. You'll still need to update LEIN_JVM_OPTS, but how you go about it will be a bit different. If you're using windows command terminal (cmd.exe) you will want to use the set command.
set LEIN_JVM_OPTS="-Djavax.net.debug=true"
The command is likely different if you're using powershell, and you can likely find out how to set that on this page on environment variables.
How do I build and run the code from github for NS3 in the link provided below
https://github.com/mkheirkhah/mptcp
it has already ns3 installation steps with mptcp
https://github.com/mkheirkhah/mptcp
this is the Installations steps go according to it ul get to know
We have tested this code on Mac (with llvm-gcc42 and python 2.7.3-11) and several Linux distributions (e.g. Red Hat with gcc4.4.7 or Ubuntu16.4 with gcc5.4.0).
Clone the MPTCP's repository
git clone https://github.com/mkheirkhah/mptcp.git
Configure and build
CXXFLAGS="-Wall" ./waf configure build
Run a simulation
./waf --run "mptcp"
https://github.com/Kashif-Nadeem/ns-3-dev-git is the more recent fork of https://github.com/teto/ns-3-dev-git/wiki which started as mkheirkhah's fork.
It should work with the latest ns-3. Compared to mkheirkhah's approach (I haven't checked if it is still valid), it tries to reuse the TCP socket code so that it can use TCP socket application. You can read more details from https://www.researchgate.net/publication/313623789_An_Implementation_of_Multipath_TCP_in_ns3
