The program was initially written to reach the goal of OpportunisticEncryption by first "securing 5% of the Internet traffic against passive wiretapping in 1996 [..] we can secure 20% the next year, against both active and passive attacks; and 80% the following year. Soon the whole Internet will be private and secure."
Starting FreeS/WAN IPsec U2.01/K1.96... /usr/lib/ipsec/eroute: pfkey write failed, returning -1 with errno=22. Invalid argument, check kernel log messages for specifics.
pfkey has changed between 1.96 and 2.x - upgrade your kernel IPSEC support to 2.x or higher.
