Problem in FTP server, need to close socket asap.

Nilson — Tue, 27 Nov 2007 19:17:48 GMT

Hi, there is my problem...

I have a ftp server listen on port 21 and another socket listen on port 5000. Port 5000 gets data from a PABX and writes in a flash.

When the flash is full, i need to close the port 5000 socket asap so i dont lose data, but what is happening is when i tell the port 5000 socket to close it takes some time and it doesnt stop to get data from pabx, so i lose data and there is a worst thing happening, the tcp buffers get full and everything stops working.

How do i clean those tcp buffers after i close the socket? Theres a way to close the socket immediatly?

Thanks.

Oh well, i thought i would have more trouble to solve this.

Setting the socket flags to as below did the job.

pabx_server_socket->so_options = SO_LINGER;
pabx_server_socket->linger = 0;

pabx_communication_socket->so_options = SO_LINGER;
pabx_communication_socket->linger = 0;

Just a friendly reminder, please include the product # in the subject line so everyone knows which device your are programming.
