Setup

Hostnames

Ensure that hostname rmq0 and rmq1 resolve to 127.0.0.1:

C:\Users\lbakken\development\lukebakken\erlang-ssl_dist_optfile-utf8 [main ↑1 +1 ~3 -0 | +0 ~4 -0 !]
> ping -n 1 rmq0

C:\Users\lbakken\development\lukebakken\erlang-ssl_dist_optfile-utf8 [main ↑1 +1 ~3 -0 | +0 ~4 -0 !]
> ping -n 1 rmq1

Run the setup script

In both the POSIX and Windows case, the setup script will generate an ssl_dist_optfile.*.conf file that should be valid, and contains the UTF-8 string Евгений

Reproduction

Windows

In a Powershell console:

.\setup.ps1
& erl.exe -proto_dist inet_tls -sname n0@rmq0 -ssl_dist_optfile .\ssl_dist_optfile.rmq0.conf
> node().

In a second Powershell console:

> & erl.exe -proto_dist inet_tls -sname n1@rmq1 -ssl_dist_optfile .\ssl_dist_optfile.rmq1.conf
net_kernel:verbose(2).
net_adm:ping('n0@rmq0').

Output

• Node n1@rmq1:

> & erl.exe -proto_dist inet_tls -sname n1@rmq1 -ssl_dist_optfile .\ssl_dist_optfile.rmq1.conf

POSIX

In a bash shell:

./setup.sh
erl -proto_dist inet_tls  -sname 'n0@rmq0' -ssl_dist_optfile ./ssl_dist_optfile.rmq0.conf
> node().

In a second bash shell:

erl -proto_dist inet_tls -sname 'n1@rmq1' -ssl_dist_optfile ./ssl_dist_optfile.rmq1.conf
> net_kernel:verbose(2).
> net_adm:ping('n0@rmq0').

Output

Output is similar to the Windows case.
