panic: EOF - sending data from windows to windows

Issue

I was trying to send files between my two windows machines and I am getting the following error.

I ran the following on Powershell on windows 10.

> cat .\LICENSE | .\croc.exe send --code test-test
Sending 'stdin' (1.1 kB)
Code is: test-test
On the other computer run

croc test-test

securing channel...2022/02/22 22:13:24 could not secure channel

Whereas when I used the WSL(which I downloaded the linux version for) I am not getting this issue.

Version

croc version v9.5.1-b0e7d4d

I cannot reproduce using windows powershell:

>cat .\test.txt | croc send --code test-test                                         Sending 'stdin' (16 B)

please answer the following:

  1. what is the version of the croc for sender and receiver
  2. what is the os for sender and receiver
  3. are you using LAN or public relay?
  4. are you using your own relay?
  5. how did you install croc?
  6. is it reproducible for you (does it happen 3 times in a row)?

  1. Version for sender and receiver are the same croc version v9.5.1-b0e7d4d which I downloaded from the official release.
  2. The OS for the sender and receiver is Windows 10 Home.
  3. I am using the default relay.
  4. No, I am not using my own relay, it's the default relay.
  5. I downloaded the binaries from the above link(release page).
  6. Yes, I am getting the same error every time, irrespective of file size.

Same exact results on Windows 11 Pro -> Windows 11 Pro through the 64 bit build for Windows

Same from Windows 11 Pro for Workstation to Raspberry Pi 4B in same LAN, public/selfhosted relay both throw out error: sender:

receiver:

However, on the exact same sender machine sending the exact same file, a VPS receiver (not same LAN of course) IS working fine.

All three machines are on croc version v9.5.6-b7e4a73 I personnally assume that this is a LAN transfer related issue.

Also getting this transferring from Windows 11 to a Linux machine (Steam Deck) on LAN.

It worked before I upgraded (on W10).

I believe I have encountered this issue, and I believe I may be able to provide some insight.

Hypothesis

There is a bug in (relating to?) the local relay when sending from a Windows machines (incl. 10 and 11 based on above comments), consistently reproducible on the latest croc version v9.6.0-0e93f1e.

My rudimentary log analysis (i.e., without a proper understanding of how croc works) leads me to believe that connections from the local relay get handled improperly, repeating the same process over and over instead of advancing the flow.

--no-local is an effective workaround.

I have a similar issue sending windows to mac-linux. it also works using --no-local. Also, coming from a non-coder, what does the local relay exactly do and why does avoiding it fix the issue??

SolarpandaS avatar Dec 09 '22 11:12 SolarpandaS

Local relay uses your LAN network to communicate. I think in some cases Windows blocks the ports needed to communicate, but I can't replicate this error (with windows -> windows or windows -> mac or mac -> linux)

schollz avatar Dec 13 '22 22:12 schollz

Are there specific ports I should open or firewall allowances I should set on either side? I can send files from Mac to PC just fine without the no-local modifier over my network.

Hi!

Same error here. Even if I switched to magic wormhole and it works from Windows to Linux without any problem on LAN, I really like croc and would want to solve this issue. @schollz, how could we help you debug this issue and provide useful information?

neurolit avatar May 03 '23 21:05 neurolit

Hi @neurolit can you make a new Issue and post your output? This issue is a conflation of several issues which have not been reproducible for me. I'm going to close this.
