options sp.ssh.access host_spec
host_spec is defined as:
host_list is a comma-separated list consisting of either a host name, an IP address, or an IP address with a netmask. A valid host name is a string and cannot contain the following characters: "=", "(", ")", "!", "*", and ",". The IP address can be either an IPv4 address or IPv6 address. An IPv4 address is of the format aaa.bbb.ccc.ddd. If the IP address contains a netmask, then the format is: aaa.bbb.ccc.ddd/mm where mm represents the number of bits from the left. An IPv6 address is of the format aaaa:bbbb:cccc:dddd:eeee:ffff:gggg:hhhh. If the IPv6 address contains a prefixlen, then the format is: aaaa:bbbb:cccc:dddd:eeee:ffff:gggg:hhhh/mm where mm represents the number of bits from the left.
The default value is * - everyone is allowed access to the SP.
The keyword all is used to grant access to all hosts. The keyword none is used to allow access to none(SSH connections cannot be made to the SP).
The host_spec can be a "*" which matches all. This is the same as the all keyword. If the host_spec is a "-", then all access is denied. This is the same as the none keyword.
