This thread looks like it nails the issue:
http://www.linuxquestions.org/questions/showthread.php?t=514191&page=2 >From the thread: "Setting back the values to those of an earlier kernel does the trick: Code: [EMAIL PROTECTED]:$ echo "4096 16384 131072" > /proc/sys/net/ipv4/tcp_wmem [EMAIL PROTECTED]:$ echo "4096 87380 174760" > /proc/sys/net/ipv4/tcp_rmem " Sure enough I checked these values and here is what they were: /proc/sys/net/ipv4/tcp_wmem 4096 16384 4194304 /proc/sys/net/ipv4/tcp_rmem 4096 87380 4194304 When I turned tcp_window_scaling back on, using these values the problem exists. I then used the values in the suggestion above and it fixes the problem. For the time being I have put these lines in my /etc/sysctl.conf: # No longer needed, fixed by lines below #net.ipv4.tcp_window_scaling=0 # Fix for tcp window scaling issue related to broken Internet routers proc.sys.net.ipv4.tcp_wmem="4096 16384 131072" proc.sys.net.ipv4.tcp_rmem="4096 87380 174760" # Default Debian values for these, still causing problems as of 2.6.18-3 #proc.sys.net.ipv4.tcp_wmem="4096 16384 4194304" #proc.sys.net.ipv4.tcp_rmem="4096 87380 4194304" -- daniel -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
