# Each protocol entry consists of:
# name: name of the probe. These are listed on the command
# line (ssh -?), plus 'regex' and 'timeout'.
# service: (optional) libwrap service name (see hosts_access(5))
# host, port: where to connect when this probe succeeds
# log_level: 0 to turn off logging
# 1 to log each incoming connection
# keepalive: Should TCP keepalive be on or off for that
# connection (default is off)
# fork: Should a new process be forked for this protocol?
# (only useful for sslh-select)
# tfo_ok: Set to true if the server supports TCP FAST OPEN
# resolve_on_forward: Set to true if server address should be resolved on
# (every) newly incoming connection (again)
# transparent: Set to true to proxy this protocol
# transparently (server sees the remote client IP
# address). Same as the global option, but per-protocol
#
# Probe-specific options:
# (sslh will try each probe in order they are declared, and
# connect to the first that matches.)

# set it as the last TLS probe
# regex:
# regex_patterns: list of patterns to match for
