Content

Program for managing DNS tunelling, includes sender and receiver. Works only for IPv4 and text files, as it doesn't support '\0' (null byte) in its messages.

Usage

For running the program, use command

make

to create binary files. Then run these files with the following arguments:

dns_sender.c

./dns_sender [-u UPSTREAM_DNS_IP] {BASE_HOST} {DST_FILEPATH} [SRC_FILEPATH]

dns_receiver.c

./dns_receiver {BASE_HOST} {DST_FILEPATH}

Examples

dns_sender.c

1. ./dns_sender -u 127.0.0.1 example.com datatxt ./data.txt

dns_receiver.c

2. ./dns_receiver example.com ./data
