[Feature Request] OpenSSL s_client ProxyCommand

[zandercodes]

Which I find a good feature if openssl s_client could be supported.

Ssh cannot lead an SNI which makes it difficult to lead TCP e.g. through a reverse proxy.
Using s_client as proxy command, SNI connections can be established by a reverse proxy.

For Example:
ssh -o ProxyCommand="openssl s_client -connect ssh.example.com:443 -quiet" root@localhost

I used traefik as reverse proxy thats is my dyn config:

tcp:
  routers:
    ssh:
      entryPoints:
        - websecure
      service: ssh
      tls: {}
      rule: HostSNI(`ssh.example.com`)
  services:
    ssh:
      loadBalancer:
        servers:
          - address: 192.168.1.100:2222
