To be precise vpnc itself seems to work as good as before but its post-connect script is now failing: $ ifconfig tun0 inet 10.99.15.144 10.99.15.144 netmask 255.255.255.255 mtu 1412 up ifconfig: ioctl (SIOCAIFADDR): File exists Where tun0 is an interface created by vpnc. ktrace gives this: ifconfig CALL socket(PF_INET,SOCK_DGRAM,IPPROTO_IP) ifconfig RET socket 3 ifconfig CALL ioctl(0x3,SIOCSIFMTU,0x525a60) ifconfig RET ioctl 0 ifconfig CALL ioctl(0x3,SIOCGIFFLAGS,0x7fffffffda30) ifconfig RET ioctl 0 ifconfig CALL ioctl(0x3,SIOCSIFFLAGS,0x7fffffffda30) ifconfig RET ioctl 0 ifconfig CALL ioctl(0x3,SIOCDIFADDR,0x525380) ifconfig RET ioctl -1 errno 49 Can't assign requested address ifconfig CALL ioctl(0x3,SIOCAIFADDR,0x525340) ifconfig RET ioctl -1 errno 17 File exists ifconfig CALL write(0x2,0x7fffffffd2d0,0xa) So, what's happening? Do you I have to update the ifconfig command? Or is there some issue in the networking code? BTW, I also get the following messages in the system log when vpnc is started: kernel: tun0: link state changed to UP kernel: ifa_add_loopback_route: insertion failed I have net.link.tap.up_on_open=1 in sysctl.conf if that matters. -- Andriy Gapon
