Hi, Just upgraded from FC2 to FC3 RC5. This line was added to /etc/rc.local: echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale However, there is no such file. Maybe this was suposed to be: echo 0 > /proc/sys/net/ipv4/tcp_window_scaling Presently: # cat /proc/sys/net/ipv4/tcp_window_scaling 1 -- Sandy Pond <sandy_pond@xxxxxxxxxxxxx>
