# $FreeBSD$ To test tcp-md5 do: * compile and install kernel with TCP_SIGNATURE support * add this to /etc/ipsec.conf (the md5 'secret' is just a sample) add 127.0.0.1 127.0.0.1 tcp 0x1000 -A tcp-md5 "0e3a9ac42ceca8260f1d6fbc46a9707c"; * enable it in /etc/rc.conf with ipsec_enable="YES" and apply it with sh /etc/rc.d/ipsec start [ off course you can also manually add it using setkey(8) ] * compile tcpconnect in here running: make * start tcpdump (secret as above, port is just a sample): tcpdump -l -n -i lo0 -s 0 -M "0e3a9ac42ceca8260f1d6fbc46a9707c" tcp and port 2345 * run the server (use same port as given to tcpdump): ./tcpconnect server 2345 * run the client (use same port as given to tcpdump): ./tcpconnect client 127.0.0.1 2345 1 tcpmd5 * check tcpdump output # end
