Kernel configuration options for Squid with tproxy

[arya6000]

I'm trying to install Squid with tproxy support and in their documentation here

https://wiki.squid-cache.org/Features/Tproxy4

The following is indicated

Requires kernel built with the configuration options:
NF_CONNTRACK=m
NETFILTER_TPROXY=m
NETFILTER_XT_MATCH_SOCKET=m
NETFILTER_XT_TARGET_TPROXY=m

Does the default Debian 9 come with a kernel with those options? or would I need to recompile the kernel with those options?

Is there anyway to check those values in my install?

Code: Select all

egrep "NF_CONNTRACK=|NETFILTER_TPROXY|NETFILTER_XT_MATCH_SOCKET|NETFILTER_XT_TARGET_TPROXY" /boot/config-$(uname -r)

Code: Select all

egrep "NF_CONNTRACK=|NETFILTER_TPROXY|NETFILTER_XT_MATCH_SOCKET|NETFILTER_XT_TARGET_TPROXY" /boot/config-$(uname -r)

I get an output for everything but "NETFILTER_TPROXY" so I assume I need to compile it myself?

Let me see...
It seems that this option is no longer needed by the other ones (socket match and TPROXY target) and was removed in kernel 3.12 by commit fd158d79d33d3c8b693e3e2d8c0e3068d529c2dc.
The squid documentation may be a bit outdated.
