-# afl-network-proxy
-
-If you want to run afl-fuzz over the network than this is what you need :)
-Note that the impact on fuzzing speed will be huge, expect a loss of 90%.
-
-## When to use this
-
-1. when you have to fuzz a target that has to run on a system that cannot
-   contain the fuzzing output (e.g. /tmp too small and file system is read-only)
-2. when the target instantly reboots on crashes
-3. ... any other reason you would need this
-
-## how to get it running
-
-### Compiling
-
-Just type `make` and let the autodetection do everything for you.
-
-Note that you will get a 40-50% performance increase if you have libdeflate-dev
-installed. The GNUmakefile will autodetect it if present.
-
-If your target has large test cases (10+kb) that are ascii only or large chunks
-of zero blocks then set `CFLAGS=-DCOMPRESS_TESTCASES=1` to compress them.
-For most targets this hurts performance though so it is disabled by default.
-
-### on the target
-
-Run `afl-network-server` with your target with the -m and -t values you need.
-Important is the -i parameter which is the TCP port to listen on.
-e.g.:
-```
-afl-network-server -i 1111 -m 25M -t 1000 -- /bin/target -f @@
-```
-
-### on the (afl-fuzz) master
-
-Just run afl-fuzz with your normal options, however the target should be
-`afl-network-client` with the IP and PORT of the `afl-network-server` and
-increase the -t value:
-```
-afl-fuzz -i in -o out -t 2000+ -- afl-network-client TARGET-IP 1111
-```
-Note the '+' on the -t parameter value. The afl-network-server will take
-care of proper timeouts hence afl-fuzz should not. The '+' increases the
-timeout and the value itself should be 500-1000 higher than the one on 
-afl-network-server.
-
-### networking
-
-The TARGET can be an IPv4 or IPv6 address, or a host name that resolves to
-either. Note that also the outgoing interface can be specified with a '%' for
-`afl-network-client`, e.g. `fe80::1234%eth0`.
-
-Also make sure your default TCP window size is larger than your MAP_SIZE
-(130kb is a good value).
-On Linux that is the middle value of `/proc/sys/net/ipv4/tcp_rmem` 
-
-## how to compile and install
-
-`make && sudo make install`
