OK. That worked. Thanks! It is worth noting that the 2.4.0-test9-pre9
kernel doesn't care about the {r,w}mem_max value (I installed 2.2.16,
2.2.17, and 2.4.0-test9-pre9 on the same machine). So I don't get
caught again later, is there different parameter that affects this
option on the 2.4.x kernel?

You need to set your /proc/sys/net/core/{w,r}mem* values large enough
for the window scale to have any reason to have a non-zero value.

Window Scale Option broken in 2.2.x
Hi: The window scale option doesn't appear to work in 2.2.16, 2.2.17, and 2.2.18. I've got an old 2.2.5 machine and it doesn't work either. Is this supposed to work? There is code in the kernel to do the window scale option, but it always sends a 0 value. It does, however, work correctly in 2.4.0-test9-pre9. I have tested it using ttcp -r -s -b131072 (the -b flag does a setsockopt to increase the receive buffer, and therefore the window size). p.s. Yes, /proc/sys/net/ipv4/tcp_window_scaling is 1 -- Lawrence ~ Lawrence MacIntyre Center for Information Infrastructure Technology [EMAIL PROTECTED] http://www.ciit.y12.doe.gov/~lpz 865.574.8696 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
