Fedora 24 Network: ERR-No Active Peers, Check Network Connection and Firewall

Reported by: notrix Owned by:
Priority: minor Milestone: undecided
Component: router/general Version: 0.9.26

Parent Tickets: Sensitive: no


Can't get i2p to work on Fedora 24.

It was working fine on the same machine and same router, with Debian Jessie, so it's probably something to do with the OS. Router port forwarding as well as Fedora's firewall-config are already done (otherwise network would not be OK, see below)

Network is Testing a bit longer than usual, then goes OK and stays that way for a while (30 minutes or more). After that it goes yellow again and shows the error in the description. No eepsites ever load.

Peers section from sidebar, while Network is still showing OK:

Active:	1 / 1
Fast:	12
High capacity:	31
Integrated:	58
Known:	111

Active goes down to 0/1 or 0/0 later on, but it never goes above 1/1.

i2p was built from git master, commit number 896af2c5d2c.
Btw I didn't put bouncycastle jar in lib this time, because there was no warning. Is that still necessary?

#1812: Can't comment on ticket 1811closed

This looks like a network connectivity issue. You reseeded fine (Known: 111) but have essentially no connections to peers (Active: 1/1, and that probably isn't working either). Something is blocking outbound or inbound UDP and/or TCP. Firewall, iptables, antivirus, external routers, …

You could try reseeding again from /configreseed in the console ('save changes and reseed now' at the bottom) but that probably won't help.

The Network: OK is obviously a false positive, things aren't OK at all.

Add a subticket #1812.

I've verified that TCP is not blocked on the configured port, by running a http server on that port and using nmap from AWS. How to test if UDP is blocked?

Dang, it's working now. Ran uninstaller.jar, removed all files (~/i2p and ~/.i2p) and reinstalled via i2pinstall_0.9.26.jar. Shouldn't have built from trunk I guess. Feel free to close the ticket.

If trunk is broken, that's a problem, and we should leave the ticket open. But we've gotten no other reports of an issue with -3. So I'd like to get to the bottom of it.
