I then ran "strace -f -e trace=network iperf -s -d -l 1424 -i 1" and: # lsmod Module Size Used by dccp_tfrc_lib 17868 0 dccp_ipv6 14916 2 dccp_ipv4 14596 3 dccp_ipv6 dccp 58176 2 dccp_ipv6,dccp_ipv4 DCCP did not load the dccp_ccid2 module. Is this the problem? Just to let you know: # cat /proc/sys/net/dccp/default/rx_ccid /proc/sys/net/dccp/default/tx_ccid 2 2 I then tested tested with 2.6.27-rc8, the same as with 2.6.27-rc4. So, what is your opinion?
