Re: [bug-inetutils] ftpd with USB gadget ethernet issue

[Alfred M. Szmidt]

   I'm trying to use the ftpd server on an Atmel AT91 ARM processor
   through a USB gadget Ethernet connection.  The issue that I'm
   seeing is that when I try to connect to the FTP server with no
   Ethernet cable attached (eth0 is down), I am unable to connect to
   the FTP server.  However, when I plug in the Ethernet cable (eth0
   is up), then everythinpg works perfectly through the usb0 Ethernet
   interface.  Is there some dependency with ftpd that requires an
   eth0 interface to be up for it to work on any interface?

How are you running ftpd (standalone, or via inetd)?  I don't see any
reason why it should misbehave like this though, could you try and
debug it further? 

   I'm also getting a bunch of "Alignment trap: ftpd (1080)
   PC=0x00012084 Instr=0xe59a3010 Address=0x00028bae FSR 0x001"
   messages when it's working properly and I'm connected.  I
   configured and built ftpd using -host=arm-linux.

Could you try and see what part of ftpd that is (using gdb, or
similar)?
