Trying to send a file with `--local` fails with `found no addresses to connect`

[DUOLabs333]

Describe the bug

I'm trying to send a file between two devices on the LAN. To try to boost the speed, I send with --local. However, when trying to connect, it fails with

[debug]    17:54:45 croc.go:561: attempt to discover peers
[debug] 17:54:45 croc.go:626: discoveries: []

[debug] 17:54:45 croc.go:655: could not connect to : found no addresses to connect

To Reproduce

Steps to reproduce the behavior:

1. Send file with croc --local send <file>
2. On the other device, try to recieve with `croc --local
3. See error

Expected behaviour

There should be no error.

Version

This is between a Windows machine and Arch Linux ARM, both with croc version v9.5.0-f210ef8

Additional context

[schollz]

Can you try again with the latest version?

[DUOLabs333]

The problem seems to be resolved.

[DUOLabs333]

This is happening again with Android phone sending to Arch Linux computer.

[schollz]

Which version and which environment are you usinf

[DUOLabs333]

Both are v9.5.6.

[DUOLabs333]

Sending from Linux to Android works fine, though.

I also got this error on v9.5.6-b7e4a73, on macOS. I tried:

croc --local .

# on the same computer
croc --local xxx

Please run with --debug and report the output

This is happening sending from Windows (9.6.0) to Arch (9.5.6):

Hi so my question is I installed croc in android using termux it works fine but since i'm running out from data i wanted to send a 2 gb file to my laptop so i figured out that i can use croc with the --local so i made i made a hotpost without internet from my phone and connected it to my laptop and shared normally from my phone using the local but it gives me the same error So my question is the thing i was doing supposed to work in the first place or not

[stefins]

@beheeddinekhelil What command are you using to send the file?

[beh-10257]

@stefins croc --local send --code anyway1234 fgbhct.blend For sending

croc anyway1234 For receiving

The error is Found no address to connect

Remember the laptop is connected to a connection without internet sice i turned off the mobile data before trying to transfer the file

Btw in the two devices the version of croc is 9.6.0-0e93f1e I guess the latest

[stefins]

@beheeddinekhelil Have you tried sending with internet on( for peer discovery)? Then also if it's not working try to host a local relay on your device and send through it!

[beh-10257]

@stefins it works fine when the internet is on without the --local option

• Isn't hosting my own relay requires mobile data
• How to receive from that local relay is it always the same Like "croc anyway01234" per exemple

[stefins]

it works fine when the internet is on without the --local option

This is for peer discovery not for actual data transmission

Isn't hosting my own relay requires mobile data

No

How to receive from that local relay is it always the same

You have to specify the relay flag for both send and receive command like croc --relay "myrelay.example.com:9009" send [filename]

[beh-10257]

@stefins so when I keep the internet on but with the --locale option it sais in the receive device That the room is not ready

Btw can i open a relay with the locale option

[stefins]

Btw can i open a relay with the locale option

no you have to run croc relay and you have to mention your local ip as the --relay argument

Croc --local still doesn't work using the same computer with internet on If you need any info, just tell me
