Can't swap: can't `list-sellers` because local peer doesn't support protocols requested by remote
Opened this issue · 15 comments
Describe the bug
#1215 but it appears on non-Whonix systems as well: I have tested it on Ubuntu, Debian, and Fedora. All produced the same problem.
This makes it impossible to actually perform swaps.
The issue arises even when talking to the quasi-official unstoppableswap.net peer:
2023-07-27T08:02:25.004881109Z DEBUG Connection established to peer peer_id=12D3KooWMiriru5viqde3BMFLTqPur8Yrjpp4ULFc76ubQLfuYYX address=/dns4/beta.unstoppableswap.net/tcp/9939/p2p/12D3KooWMiriru5viqde3BMFLTqPur8Yrjpp4ULFc76ubQLfuYYX

Therefore it seems unlikely to be the result of sellers using outdated software. I assume unstoppableswap.net keeps theirs updated.

Platform (please complete the following information):
- CLI
swapbinary - Software Version [e.g. 0.8.3]
swap 0.12.1 - Operating System: [e.g. Ubuntu]
Debian 11.7
The problem seems to come from the libp2p library: the "Ignoring seller" message comes from swap/src/cli/list_sellers.rs and is the product of an InboundFailure.
Next step might be to find out which protocols the remote is asking for, and which protocols the local swap supports, and see why there is a mismatch. Both asb and swap appear to use the same Cargo.toml so it is not a question of library version mismatch.
Using a different rendezvous point works, because one of the sellers on this rendezvous point supports the correct protocols.

Very strange... Now one of the sellers on the unstoppableswap.net rendezvous point is also showing up in the table when I do list-sellers with that rendezvous point, indicating the swap client and the seller were able to negotiate a connection. Previously this seller produced the previously-described protocol error and the table of sellers was empty.
The "official" unstoppableswap.net seller is still not showing up, however.
I've seen this before, but couldn't narrow it down at the time :(
It seemed to happen only over Tor, I don't think I ever had the issue when using DNS/TCP.
@thomaseizinger is this something you have any insight on?
It's possible upgrading libp2p could help with this, this thread has some useful info: libp2p/rust-libp2p#3605
Unfortunately upgrading libp2p is a major task
It seemed to happen only over Tor, I don't think I ever had the issue when using DNS/TCP.
I saw this issue when testing over clearnet and also when testing over Tor
@thomaseizinger is this something you have any insight on?
Unfortunately no. You are running on libp2p 0.42.2 which is 1.5 years old. I am happy to answer any questions regarding updating to the latest version. I'd suggest you open a draft PR and then we can discuss things there.
How can it be that we are still receiving a quote?

Correction: looks like I was wrong when I suggested I had also got this problem over clearnet.
swap by default automatically uses any running Tor instance and I had Tor running on all systems that I tested this with.
Therefore all my tests (and failures) ran over Tor.
Running with
$ ./swap --debug list-sellers --rendezvous-point /dns4/discover.unstoppableswap.net/tcp/8888/p2p/12D3KooWA6cnqJpVnreBVnoro8midDL9Lpzmg8oJPoAGi7YYaamE --tor-socks5-port 0
results in a successful handshake with all non-Tor sellers.
Since some sellers are only accessible via Tor, this is a terrible workaround!
I will put a 1 XMR bounty on this. Happy to send it to one of the maintainers for escrow.
Unfortunately upgrading libp2p is a major task
My approach to upgrading libraries is usually:
- bump the version in Cargo.toml
- commit once the compiler stops complaining
:)
is this fixed? i'm having the exact issue at v0.12.3
This appears to be an issue still, and occurs regardless of if I'm using tor or not. Any progress on a fix or ETA for a workaround?

Would you still be open to assisting with the upgrade? I don't know how much time you guys have to spare.
I have opened a draft PR here: UnstoppableSwap#109 and will be working on this over the coming days / weeks
I am no longer a rust-libp2p maintainer. Many things have changed (for the better) there since this was built. My suggestion would be to take a holistic approach where you look at what rust-libp2p offers today, design a new network layer and throw the current one out.
