If FTP behaves similarly it might not matter lots, I guess. (I was thinking that if the receiver wasn't actually reading the data, it could cause this, but then we'd see different window size advertisements from receiver to sender.) > if i do that in that two box, > vice versa. > I've tried to turn off rfc1323 and rfc1644 option, still doesn't work. > Any hint ? Ummm. Let me ask this one more time....what's the network path like between your two machines? I assume at this point the SCO box is trying to shove a huge file over the FreeBSD machine, right? What happens if you try to go the opposite direction? (Is that what you meant by "vice versa" above?) Also, where is your tcpdump trace being taken? Is it on one of the two endhosts or at some point in the middle? Do you regularly do other types of communication over this path (e.g. HTTP, telnet, anything?)? If so, how do they fare?
