Topic: EchoServer gives file open error

Hello everyone.

This is my second post, I removed the previous one.

What i am trying to do is to run minimal example. I want to understand basic API structure and library design of wolfssl, so i tried to run this minimal example:

https://www.wolfssl.com/docs/wolfssl-manual/ch11/

I attached the error with an SS.

Re: EchoServer gives file open error

Hi burakkirazli,

You must run the example from the wolfssl-root like:
./examples/echoserver/echoserver

Also you can find some simple TLS examples in our wolfssl-examples repo here:
https://github.com/wolfSSL/wolfssl-examples

Thanks,
David Garske, wolfSSL

Re: EchoServer gives file open error

Hi burakkirazli,

Please go to the directory where you ran your tests and run this command:

ls -la ../certs/ || echo "Directory not found"

Do you see a list of certs displayed or do you see this:

$ ls -la ../certs/ || echo "Directory not found"
ls: ../certs/: No such file or directory
Directory not found

If the directory is not there please copy/paste the certs/ directory from the wolfSSL download to that location and try running the example again, let us know if you continue to have issues.

Warm Regards,

K
