Hi Folks, I have a odd issue that I would throw out for some ideas - if someone has any.
I am using the Microblaze uCLinux port, specifically on the 10/100 ethernet side. Everything seems fine, telnet, tftp, and net-perf work great. Net-perf reports a 6Mb/s data rate to a WindowsXP box - and I think that is fine. Tftp transfers around 150KB/s, which is fine for me as well. However, ftp is another story. If I try to ftp from the uCLinux O/s and get an image from an ftp server running on our local network, here is what happens 1) connect and login ~2-3 seconds 2) get the file 3) now, the first 1-2KB comes immediate, then the next 2-3 KB/s takes about 10 seconds, then the next 2-3KB/s takes about 20 seconds. Then the ftp server (on the remote windows xp box) times out The same process happens if I try to ftp a file from a windows system to the uclinux O/s (ftpd triggered by inetd) However, I can ftp from a linux box to the uCLinux O/s at a rate of about 20KB/s - seems slow but at least it works for all file sizes. Using ethereal, I see that the linux box transfer is a collected of tcp sends and acks from the board. Using ethereal, I see that the transfer between the uCLinix O/S and any windows box, seems to be missing a lot of acks? In particular, if I try to "get" a file from a windows xp FTP server on our network (this is using FTP from the uCLinux O/S), I see some tcp packets sent from the windows xp server, then some re-transmissions, then uCLinux sends an ACK....then nothing else is sent from the ftp sever for 10-20 seconds. It seems like things get slower and slower after every packet ack that the ucLinux O/s sends out. Has anyone seen anything like this or have any idea for me to look at? Thanks!
