This includes variables which are set via other variables in /etc/rc.conf, including: rc.conf rc.network tcp_drop_synfin net.inet.tcp.drop_synfin tcp_restrict_rst net.inet.tcp.restrict_rst net.inet.tcp.rfc1323 net.inet.tcp.rfc1644 net.inet.tcp.mssdflt net.inet.tcp.sendspace net.inet.tcp.recvspace net.inet.tcp.v6mssdflt net.inet.tcp.slowstart_flightsize net.inet.tcp.local_slowstart_flightsize net.inet.tcp.syncookies net.inet.tcp.syncache.bucketlimit net.inet.tcp.syncache.cachelimit net.inet.tcp.syncache.count net.inet.tcp.syncache.hashsize net.inet.tcp.syncache.rexmtlimit net.inet.tcp.rexmit_min net.inet.tcp.rexmit_slop net.inet.icmp.maskrepl net.inet.icmp.icmplim icmp_drop_redirect net.inet.icmp.drop_redirect icmp_log_redirect net.inet.icmp.log_redirect net.inet.icmp.icmplim_output icmp_bmcastecho net.inet.icmp.bmcastecho net.inet6.icmp6.rediraccept net.inet6.icmp6.redirtimeout net.inet6.icmp6.nd6_prune net.inet6.icmp6.nd6_delay net.inet6.icmp6.nd6_umaxtries net.inet6.icmp6.nd6_mmaxtries net.inet6.icmp6.nd6_useloopback net.inet6.icmp6.nodeinfo net.inet6.icmp6.errppslimit net.inet6.icmp6.nd6_maxnudhint net.inet6.icmp6.nd6_debug This is not an exhaustive list; indeed, I don't know how to find one. But it's difficult to use an undocumented system, so we should do something about it. In addition, the tcp(4) man page contains descriptions of the (presumably obsolete) sysctls tcp.slowstart_flightsize and tcp.local_slowstart_flightsize. >How-To-Repeat: Create FreeBSD the way it has already been done. Or don't bother trying to repeat. >Fix: This looks to be an issue for the people who implemented the sysctls. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-doc" in the body of the message
