packetd

Userspace packet processing daemon

Building locally

You'll need an Untangle mirror to get the patched libnetfilter-queue-dev:

apt-get install libnetfilter-log-dev libnetfilter-queue-dev libnetfilter-conntrack-dev

You will also need to install several golang packages dependencies:

go get -u github.com/gin-gonic/gin
go get -u github.com/gin-contrib/cors
go get -u github.com/google/gopacket
go get -u github.com/mattn/go-sqlite3
go get -u github.com/oschwald/geoip2-golang

Then build the regular way:

go build

If you want to use the golint tool, you can install it with this command:

go get -u golang.org/x/lint/golint

You can run golint with the following command: (assumes GOPATH=~/golang)

~/golang/bin/golint github.com/untangle/packetd/...

Building in docker

For this to work you have to have your clone under a path of the form:

[...]/src/github.com/untangle/packetd

libc target

docker-compose -f docker-compose.build.yml up --build libc

Result:

# file ./packetd
./packetd: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=7459d11c6fd1dd3ed5d3e3ed5c2320e27dc4bea4, with debug_info, not stripped

MUSL target

docker-compose -f docker-compose.build.yml up --build musl

Result:

# file ./packetd
./packetd: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-musl-x86_64.so.1, with debug_info, not stripped

Running it

You'll also need an Untangle mirror for most of those:

apt-get install untangle-classd untangle-geoip-database untangle-python3-sync-settings libnetfilter-log1 libnetfilter-queue1 libnetfilter-conntrack3

Then:

./packetd

golint

Get golint:

go get -u golang.org/x/lint/golint

Use it:

${GOPATH}/bin/golint $(pwd)/...
