What version of Codex is running?

0.42.0

Which model were you using?

gpt-5-codex high

What platform is your computer?

Microsoft Windows NT 10.0.19045.0 x64

What steps can reproduce the bug?

Launch codex cli under wsl in Windows 10, ask Codex to launch this command:
cmd.exe /c build.bat

Codex fails with this error:
Ran cmd.exe /c build.bat
└ <3>WSL (931 - ) ERROR: UtilBindVsockAnyPort:307: socket failed 1

What is the expected behavior?

command is run

What do you see instead?

Ran cmd.exe /c build.bat
└ <3>WSL (931 - ) ERROR: UtilBindVsockAnyPort:307: socket failed 1

I noticed that when Codex CLI adjusted command timeout - command worked successfully. Maybe there is a way to setup command timeouts in config file?

yeah I came across this issue too, and I also found that letting codex adjust bash tool timeout argument solved the problem, kind of weird

same issue

I found that wrapping the actual command in double quotes fixes the issue cmd.exe /c "tasklist | findstr build"

We've made a bunch of improvements for WSL in recent versions. I think this issue may no longer be relevant. I'll keep it open until someone is able to confirm.

As of v0.80.0 this problem still exists. I tried wrapping the command in double-quotes and without, same result.

I encountered this problem, but solved changing permission to full access.
