Using the main dialog you can set:
- State of the transport, that is: status, "Connect", name of the storage (containing the configuration), a list with information about the active connections and supported ciphers.
- Identifier, name and description of the transport.
- Address of the transport in the format "{addr}[:{port}[,{port2}[,{portN}]][:{mode}[:{IDmess}]]]", where:
- addr — address to open SSL, it must be one of the addresses of the host. Empty or "*" address opens SSL for all interfaces. There may be as the symbolic representation as well as IPv4 "127.0.0.1" or IPv6 "[::1]".
- port, port2, portN — network ports on which SSL is sequential opened (at busy the first ones), indication of the character name of the port, according to /etc/services is available.
- mode – mode of operation:
- 0(default) — ordinal connection;
- 2 — initiative connection. Enables the mode of connecting this input transport to remote host (address instead of local) and switching to the listening state of this host. The "Keep alive timeout" value is used as the timeout of the re-connection of this transport in the absence of activity in order to restore the possibly lost connection.
- IDmess — identification message of the initiative connection — the mode 2.
- Selecting of the transport protocols.
- State "Connect", in which the transport must be switched at start up.
