No timeout on RTCS FTP server ?

lucky06200 — Wed, 04 Dec 2013 10:27:40 GMT

Hello,

I use ftpd server with only one session on ARM M4 (K60) + MQX 4.0.0 + RTCS 3.08

When active connection exist, and there is no more trafic, server do not close the connection (no timeout).

So, server is locked for other client.

How can i have a connection close when no traffic occurs during a given time ?

Is this possible to change socket option, for example (in ftpd.c code if needed) ?

If yes, wich option is OK for this ?

Or may be i need to write code in my application for this ?

Best regards,

Luc

I found a solution to my problem.I add a socket option (FTPDCFG_RECEIVE_TIMEOUT) in FTPd_task.

Something like :

(around line 150)

if (!error) {
option = FTPDCFG_CONNECT_TIMEOUT;
error = setsockopt(listensock, SOL_TCP, OPT_CONNECT_TIMEOUT, &option, sizeof(option));
}

if (!error) {
option = FTPDCFG_TIMEWAIT_TIMEOUT;
error = setsockopt(listensock, SOL_TCP, OPT_TIMEWAIT_TIMEOUT, &option, sizeof(option));
}

if (!error) {
option = FTPDCFG_RECEIVE_TIMEOUT; // Set this value to what you need (360000 for 6 minute, for me)
error = setsockopt(listensock, SOL_TCP, OPT_RECEIVE_TIMEOUT, &option, sizeof(option));
}

if (!error) {
error = bind(listensock, (const sockaddr *)&laddr, sizeof(laddr));
}

if (!error) {
error = listen(listensock, 0);
}

if (error) {
RTCS_task_exit(creator, error);
}
RTCS_task_resume_creator(creator, RTCS_OK);

So, ftpd exit after no trafic during 6 min.
