Please answer the following before submitting your issue:

Note: Please include any substantial examples (debug session output, stacktraces, etc) as linked gists.

  1. What version of Delve are you using (dlv version)? Delve Debugger Version: 1.2.0 Build: $Id: 068e2451004e95d0b042e5257e34f0f08ce01466 $

  2. What version of Go are you using? (go version)? go version go1.11.5 linux/amd64

  3. What operating system and processor architecture are you using? Linux 4.4.0-43-x86_64 GNU/Linux

  4. What did you do? dlv debug ~/python-buildpack/src/python/supply/cli/main.go --backend=native --headless --listen=127.0.1.1:2345 --log --api-version 1 --accept-multiclient -- "/home/ivan/fuzzy/ /tmp/fuzzy /home/ivan/fuzzy/.cloudfoundry 0"

This produces the following lines: API server listening at: 127.0.1.1:2345 INFO[0002] launching process with args: [/home/ivan/python-buildpack/bin/debug /home/ivan/fuzzy /tmp/fuzzy /home/ivan/fuzzy/.cloudfoundry 0] layer=debugger

  1. What did you expect to see? When I try to connect remotely, with the following command:

dlv connect 127.0.1.1:2345 --log

  1. What did you see instead? I get nothing. There isn't even a connection refused or any response whatsoever. I am also unable to stop the process by hitting CTRL+C (I must kill its PID).

If I telnet to ip/port I can see the connection is opened. There is no connection refused - so there is no firewall issues.

Any ideas?

Best regards, Ivan

This mechanism is the same mechanism used by all delve frontends to talk to delve, if it didn't work they wouldn't work either, therefore it's almost certainly a problem with your network configuration.
