Message: 95988   

Hello,

I have modified my romfs/etc/inetd.conf file to not start ftpd though inetd process once kernel boots.  Now, when I run ftpd manually using "ftpd -D" command ftp server is not started(-D option to run as standalone process).

Could any one help me on this?

Regards,

Parimala

Hello Mike,

I have enabled NetworkApplications/ftpd, I think it uses user/ftpd code.

you'll have to enable HAVE_DAEMON in user/ftpd/config.h

although i dont know why you'd stop using inetd ... the entire point of it is to avoid multiple servers being resident all the time

Hello Mike,

/* Define to one if you have 'daemon' function */

#ifdef __uClinux__

#undef HAVE_DAEMON

#else

#define HAVE_DAEMON 1

#endif

Do I need to change this file manually, define HAVE_DAEMON to 1 in case of ifdef __uClinux__ or Is there any other way to change this?

I am stopping ftpd though inetd because I have to start ftpd from my application.

Regards,

Parimala

Hello Mike,

Cleaning & compiling the new Image made "ftpd -D -d" to run as a standalone process. Now, I am able to connect to uClinux ftp server & can run ftp commands. But once I quit the session following error message is logged

How can I avoid this? I don't see this while running ftpd through inetd.

Does this ftpd handles multiple connection simultaneously as a standalone process?

Hello Mike,

OK, I will try with the latest version. My requirement is ftpd should be started by default on reboot, it should be started when my application starts.
