>Description:
Attempting slightly stronger dogfooding revealed some problems. SSH doesn't appear to work. Running with ssh -vvv, I get stuck after this:

debug1: kex: algorithm: curve25519-sha256%libssh.org@localhost
debug1: kex: host key algorithm: ssh-ed25519
debug1: REQUESTED ENC.NAME is 'chacha20-poly1305%openssh.com@localhost'
debug1: kex: server->client cipher: chacha20-poly1305%openssh.com@localhost MAC: <implicit> compression: none
debug1: REQUESTED ENC.NAME is 'chacha20-poly1305%openssh.com@localhost'
debug1: kex: client->server cipher: chacha20-poly1305%openssh.com@localhost MAC: <implicit> compression: none
debug3: send packet: type 30
debug2: mac 0x0, -1 -1
debug1: expecting SSH2_MSG_KEX_ECDH_REPLY

This issue occurs on an open network too.

Second issue, which is unrelated.
Trying to use wpa_supplicant in the foreground rather than as a service and using WPA rather than an open network, I got messages like:
WPA: EAPOL-Key Replay Counter did not increase - dropping packet"

However the connection seems to work.

no idea so far.
