DBInstaller and FTP Server port 5000 conflict

[anders0ny]

Hello, I found a conflict between Sphaira's FTP-srv and DBInstaller.

When I start DBI through Sphaira and try to start its FTP service, I get an error:

Starting port 5000: Error: address already in use.

I went to the FPT-srv configuration and changed the port to 5001, and DBI started working again.

One of the two will need to change the FTP port for the solution to work correctly.

well, that is very very strange!

the ftp server is always closed on exit,

sphaira/sphaira/source/ftpsrv_helper.cpp

Lines 32 to 43 in 9390bd3

	void loop(void* arg) {
	while (!g_should_exit) {
	ftpsrv_init(&g_ftpsrv_config);
	while (!g_should_exit) {
	if (ftpsrv_loop(100) != FTP_API_LOOP_ERROR_OK) {
	svcSleepThread(1e+6);
	break;
	}
	}
	ftpsrv_exit();
	}
	}

and the call to exit is made here

sphaira/sphaira/source/app.cpp

Line 1481 in 9390bd3

ftpsrv::Exit();

closing the server itself is done here https://github.com/ITotalJustice/ftpsrv/blob/e8ef5f9e9f168bc25a03a22e93f32c4912c4d003/src/ftpsrv.c#L1776 which does the following https://github.com/ITotalJustice/ftpsrv/blob/e8ef5f9e9f168bc25a03a22e93f32c4912c4d003/src/ftpsrv.c#L493-L494

tldr, it properly closes the socket. I also can't reproduce this at all 😄 Do you have ftpsrv installed as a sysmodule by any chance?

Normally, if you have a ftp server as a sysmodule but you want to use a homebrew-specific one, you should first disable the sysmodule.

Hey!! Yes.... So I think this could be a problem with the AWS that I'm using and that most of Brazil uses hahahah it's called CNX, it already comes with the ftp-sys module active in the background... and in the latest version it removed HBMenu and left Sphaira as their main Menu, here I changed the port of mine to 5001 and I no longer have a conflict, I made a video on my channel showing subscribers how to disable or change the port... I'll talk to the CNX guys about this issue on their Github then :)

My dbi 658 is already configured with port 7000 and I haven't had any problems so far.
It's easier to edit the DBi port
