Broken when running against solana-test-validator #175

Seems to fail when using localhost versus a direct ip

Probably IPv6 failure. Does ws://[::1]:8900/ work?

Unfortunately, Websocat v1 does not properly support Happy Eyeballs (unlike Websocat v3), so if hostname resovles to multiple IPs, it would work reliably if all of them work (e.g. if server listens for IPv6+IPv4 instead of just IPv4).

Duplicate of #23.

Unfortunately the ipv6 endpoint doesn't work:

➜  ~ websocat -v "ws://[::1]:8900/"
[INFO  websocat::lints] Auto-inserting the line mode

[INFO  websocat::ws_client_peer] get_ws_client_peer

By default the service listens to ipv4 only:

➜  ~ sudo ss -tulpn | grep 8900
tcp   LISTEN 0      1024                                     0.0.0.0:8900       0.0.0.0:*    users:(("solana-test-val",pid=298084,fd=85))
