[openssl-users] Help : TLS 1.3 Server is not listening on the default port

[Chakrapani Reddy]

Hello,

Wanted to try to capture the TLS1.3 message flow using openssl-1.1.1-pre7
and used the below command to run the server.
[root at vm bin]# pwd
/opt/build/openssl-1.1.1-pre7/bin

*[root at vm bin]# ./openssl s_server -cert server.crt -key server1.key*

But it is throwing the below error :

Using default temp DH parameters

*47306412798048:error:02004061:system
library:socket:unknown:crypto/bio/b_sock2.c:49:47306412798048:error:2008C076:BIO

 ldd ./openssl
        linux-vdso.so.1 =>  (0x00007fff6c9fd000)
        libdl.so.2 => /lib64/libdl.so.2 (0x0000003fc2200000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003fc2a00000)
        libc.so.6 => /lib64/libc.so.6 (0x0000003fc1e00000)
        /lib64/ld-linux-x86-64.so.2 (0x0000003fc1600000)

Shall we know how to make it working?

Best Regards,
Chakrapani
