Some parameters may be needed to set before using TCP. On SSL or web socket communication, especially, SSL setting is required before connection by set command of pid_ioctl function.
pid_ioctl($pid, "set ITEM VALUE");
ITEM means setting items and VALUE is possible value of the item.
| ITEM | VALUE | Description | |
|---|---|---|---|
| nodelay | 0 | Enable Nagle algorithm | |
| 1 | Disable Nagle algorithm | ||
| api | ssl | Use SSL | |
| tls | Use SSL ※ available on F/W 1.5.0 or later |
||
| ws | Use Web Socket server | ||
| ssl method | client | SSL client (version: automatic) ※ available on F/W 1.3.1 or later |
|
| server | SSL server (version: automatic) ※ available on F/W 1.3.1 or later |
||
| ws | path | PATH | Set path of web socket URI |
| mode | 0 | Set data type of web socket: text | |
| 1 | Set data type of web socket: binary | ||
| proto | PROTOCOL | Set protocol of web socket | |
| origin | ADDR | Specify a host to allow connection | |
※ Note : It is recommended to set "ssl method" to "client" or "server".(required to use F/W 1.3.1 or later)
※ Note : Both "ssl3_client" and "ssl3_server" commands on "ssl method" are no more supported on F/W 1.5.0 or later.
※ Note : Both "tls1_client" and "tls1_server" commands on "ssl method" are no more supported on F/W 2.1.0 or later.
※ Note : Both "telnet" and "ssh" commands on "api" are no more supported on F/W 2.1.0 or later.
※ Caution : TCP Nagle Algorithm is to improve effective data transmission by reducing the number of segments. Thus, it may accompany a little delay.
※ Caution : Only TCP 0 to 3 are available for setting SSL. In addition, it is not possible to set the TCP id to another api mode before product reboots.
