Description Benedikt Gollatz 2011-03-03 14:21:34 UTC

Version:           unspecified (using KDE 4.5.5) 
OS:                Linux

When operating a dual-stack IPv6/IPv4 setup and announcing a torrent on a tracker that is both reachable via IPv6 and IPv4, ktorrent connects to the tracker only via IPv6, announces only its IPv6 address and only receives IPv6 peers from the tracker, which keeps separate IPv6 and IPv4 client pools. As a consequence, dual-stack hosts cannot see IPv4-only peers and vice versa.

Reproducible: Always

Steps to Reproduce:
1. Set up working IPv6 and IPv4 on host1.
2. Create torrent, announce on IPv6- and IPv4-enabled tracker like <http://tracker.ccc.de/announce>.
3. Open torrent on exclusively IPv4-connected host2.

Actual Results:  
host1 and host2 get a distinct set of peers (IPv6 pool and IPv4 pool), even though they are theoretically interconnectible. Due to the current lack of popularity of IPv6, host1 may not see any peers at all.

Expected Results:  
host1 contacts tracker both via IPv4 and IPv6, thus acquiring both IPv6 and IPv4 peer addresses and announcing both its IPv4 and IPv6 address to the tracker.

In the advanced settings, is do not use KIO for tracker announces enabled ?

Comment 2 Benedikt Gollatz 2011-03-04 10:59:59 UTC

It is. Unfortunately, tracker.ccc.de appears not to listen on IPv6 any more (TCP reset), so I cannot test whether the behaviour changes if I disable that option.
