I'm using Digital Ocean's Ubuntu 14.04 image and needs the kernel to be compiled for TPROXY. Is there a way to check whether the current kernel supports TPROXY?

On SUse 11 Sp2

 node01:~ # grep TPROXY /boot/config-3.0.38-0.5-default 
 CONFIG_NETFILTER_TPROXY=m
 CONFIG_NETFILTER_XT_TARGET_TPROXY=m
 node01:~ # uname -r
 3.0.38-0.5-default

I don't knwo the kernel version of ubuntu 14, but anyway, try grep in your kernel config under /boot Filesystem

Did the grep on the config and got CONFIG_NETFILTER_XT_TARGET_TPROXY=m but not CONFIG_NETFILTER_TPROXY=m. What does m means and does not having the other line means TPROXY is not supported? –  Nyxynyx Aug 19 at 16:22
    
m means it is compiled as a kernel module. TPROXY IS supported on the default Ubuntu 14.04 kernels. –  Florin Asavoaie Aug 19 at 16:58
