by building ipxe with debug flags enabled you could get some more info on client side as well
make bin/undionly.kpxe DEBUG=ftp

However you might need some more flags to get enough info about the transfer to be useful. However together with a TCP dump for the same sessions it should be enugh to figure out what is going on.

I did recompiled ipxe with DEBUG=ftp flag and here is the result :

FTP 0x27794 fetching /sda/ipxe/modules/liveiso/tinycore/tinycore.iso
http://ftp.admin@***@192.168.2.1//sda/ip...nycore.iso
FTP 0x27794 received status 220
FTP 0x27794 sending USER admin
FTP 0x27794 received status 331
FTP 0x27794 sending PASS ***
FTP 0x27794 received status 230
FTP 0x27794 sending TYPE I
FTP 0x27794 received status 200
FTP 0x27794 sending SIZE /sda/ipxe/modules/liveiso/tinycore/tinycore.iso
FTP 0x27794 received status 550
FTP 0x27794 sending PASV
FTP 0x27794 received status 227
FTP 0x27794 sending RETR /sda/ipxe/modules/liveiso/tinycore/tinycore.iso
FTP 0x27794 received status 150
100%

After all this debug info is displayed i need to wait 5 min and tinycore boot .
