--detach not working

[Manuel Portillo]

Affected Version

master, I also tried 2.0 but I didn't look at the logs then, so I am not sure if the same error was showing there.

Expected Behavior

starting a remote alias with --detach flag should make the tunnel available

Current Behavior

after starting using the alias, I get the proper messages on the output, but the tunnel is not actually running, looking at the logs, I can see the following:

cat mole.log

Error: unknown flag: --id
Usage:
  mole start [flags]
  mole start [command]

Available Commands:
  alias       Starts a ssh tunnel by alias
  local       Starts a ssh local port forwarding tunnel
  remote      Starts a ssh remote port forwarding tunnel

Flags:
  -h, --help   help for start

Use "mole start [command] --help" for more information about a command.

Steps to Reproduce

1. create an alias mole add alias remote pi4gameserver -S 0.0.0.0:2222 -d localhost:22 -s [e-mail]:666
2. start mole detached mole start alias pi4gameserver --detach, this one outputs the following:

INFO[0000] instance identifier is pi4gameserver
INFO[0000] execute "mole stop pi4gameserver" if you like to stop it at any time

3. Nothing works, checking ps, there is no mole, checking the tunnel it doesn't exist and the logs show what I mentioned above:

Error: unknown flag: --id
Usage:
  mole start [flags]
  mole start [command]

Available Commands:
  alias       Starts a ssh tunnel by alias
  local       Starts a ssh local port forwarding tunnel
  remote      Starts a ssh remote port forwarding tunnel

Flags:
  -h, --help   help for start

Use "mole start [command] --help" for more information about a command.

4. Running without --detach works fine

This functionality is broken for me as well.

[zieglar]

same for me, detach not working, version 2.0.0

[David Pinheiro]

@manuel220x, thank you for reporting it.

I want to apologize for the time it is taking for fixing this bug but I’ve been busy with work and family and had no time to spend on this project. Hopefully I can find some time to fix it soon.

[Alon Sabi]

Yep, definitely broken, otherwise works like a charm! 😅 happy holidays.

[Jimmie Han]

I found start alias --detach not work as expected, then a found this issue, i try to debug and fix it:

1. cat ~/.mole/pg}/mole.log and found the problem is missing --id flag logic.

Error: unknown flag: --id
Usage:
  mole start alias [name] [flags]

Flags:
  -x, --detach     run process in background
  -h, --help       help for alias
  -i, --insecure   skip host key validation when connecting to ssh server
  -v, --verbose    increase log verbosity

2. fix it #184.
3. go run main.go start alias pg -x works find.

git clone https://github.com/hanjm/mole.git && \
cd mole && \
git checkout fix/fix-start-alias-detach && \
go build -o $(go env GOPATH)/bin/mole

There might be build error on Mac OS 12.4 with go1.18.3 while build make and build test on @hanjm's fix
a simple upgrade may fix go get -u golang.org/x/sys

Detach is not working on Ubuntu :
I am using the latest release v2.0

After creating the tunnel when I check the log this is the output

time="2022-10-30T18:45:25Z" level=error msg="can't start. Another instance is already using the same id" id=bbee01f4
time="2022-10-30T18:45:25Z" level=error msg="error starting mole" error="can't start. Another instance is already using the same id bbee01f4"

There are no tunnels with the same ID.
Happens every time I run this but works fine when I run it without the detach parameter.

[: ask me anything :)]

Not working as well, I've manually installed golang version with go1.17.12 darwin/arm64 by brew install go@1.17
