Lightweight packet manipulation script built on top of the Linux NFQUEUE. Designed to simulate common forms of network degradation.
Effects
- Latency
- Packet loss
- Restricted bandwidth
- Packet surges
Extra features
- Printing packets
- Display current bandwidth
- Saving to .pcap files
- Filter by protocol
Download the pre-compiled binary
sudo apt-get install build-essential python-dev libnetfilter-queue-dev
sudo pip install -r requirements.txt
Install aur/python-netfilterqueue-git https://aur.archlinux.org/packages/python-netfilterqueue-git/
sudo pip install -r requirements.txt
Run sudo Parcel.py -h for the usage
Command will print all packets flowing in and out of the current machine:
sudo python Parcel.py -p
To filter for certain packets for a certain protocol the -tp is used:
sudo python Parcel.py -p -tp TCP
EFFECTS
Only one effect can be selected
-p Prints all the packets
-i Does nothing to the packets. Used to show how much default overhead there is
-b Displays information on the transfer rate
-l <delay_ms> Applies latency on the connection
-pl <percentage> Performs packet loss on the connection
-t <delay_ms> Creates a packet surge on a connection by the given delay
-rl <rate_bytes> Limits the throughput of the program
OPTIONS
Can be used with any effect
-tp <packet-type> Only performs an effect on the specified packet type
-s <filename> Saves all collected packets into a .pcap file
