Network Weather Update: Still Stormy, Suggested Short-Term Mitigations
The I2P network is currently under a Denial-of-Service attack. This attack affects I2P and i2pd but in different ways and is having a serious effect on network health. Reachability of I2P sites is badly degraded.
Java I2P users are suggested to disable the sybil attack tool, delete the sybil-blocklist, and re-start their routers.
To disable the sybil attack detector tool
Open the sybil attack detector in your router console at 127.0.0.1:7657/netdb?f=3&m=15
Change “Background Analysis Run Frequency” to “Never”
Click “Save” to save the settings.
To delete the sybil blocklist, run:
On Debian and Ubuntu:
rm “/var/lib/i2p/i2p-config/sybil-analysis/blocklist-sybil.txt”
On other Linuxes and on Mac OSX:
rm “$HOME/.i2p/sybil-analysis/blocklist-sybil.txt”
And on Windows:
del %LocalAppData%\i2p\sybil-analysis\blocklist-sybil.txt"
When you are finished, re-start your I2P router.
If you are hosting a service inside I2P and it is hosted on a Floodfill router, you should consider multihoming the service on a Floodfill-disabled router to improve reachability. Other mitigations are being discussed but a long-term, backward-compatible solution is still being worked on.
