Created attachment 887173 [details] fix for the crash If nuttcp (server) is run under the docker fedora image where /proc/sys/net/ipv4/tcp_adv_win_scale does not exist, it crashes. The last lines of strace are shown below: getsockopt(6, SOL_SOCKET, SO_RCVBUF, [374400], [4]) = 0 open("/proc/sys/net/ipv4/tcp_adv_win_scale", O_RDONLY) = -1 ENOENT (No such file or directory) --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV (core dumped) +++ Segmentation fault (core dumped)
Can we have a fix for that in f20? Nuttcp is especially useful in docker images used for testing.
