v055c: Unable to share file through termux python over http.server over LAN

[barkoder]

Steps to reproduce:

0. Install ReThink v0.5.5c

1. Install and open Termux.

2. Install python in termux - pkg install python

3. echo test > test.file in termux.

4. Start http-server - python3 -m http.server 12345

5. curl -O http://<LOCAL_IP_ADDRESS_OF_YOUR_ANDROID_DEVICE>:12345/test.file on a different computer on your local network. This step fails unless you turn off Rethink altogether. Switching to DNS only or Firewall only mode in ReThink doesn't work.

6. Also the Network log and DNS Log on ReThink shows nothing regarding this request.

I remember an older version of ReThink used to work on Step 5.

Thanks.

Thanks. In general, we haven't checked if unconnected UDP sockets and server TCP sockets work in all scenarios as at least running TCP servers is a very uncommon thing to do (unconnected UDP sockets are slightly more common but apps don't rely on it solely so it never manifests as a bug, except in cases where it does: #1323).

Two ways to work around this problem:

1. Exclude Termux (from Configure -> Apps) from Rethink
2. Turn ON Do not route Private IPs (from Configure -> Network).

Thanks @ignoramous . That works!

It would help if the Network log showed that it was being blocked and also why it was being blocked.

It isn't blocked. I believe Android doesn't even send us the packets for server TCP sockets. I might be wrong. As mentioned above, we haven't really dug in to this.

In v055j (github, website), we've brought back the previous behaviour of "excluding" proxy-running apps like Termux. Please test on v055j and let us know.

To toggle this behaviour, go to turn ON/OFF Configure -> Network -> Loopback proxy forwarder apps (to be clear, in this case, OFF is what would "exclude" Termux and hopefully make it work).

v055j is on now f-droid too (closing this issue, feel free to reopen) if it hasn't fixed for you.
