Hi Gianluca, On Sun, 26 Mar 2023 13:42:19 +0100 "Gianluca Stivan" <me(a)yawnt.com> wrote:Hi, Thank you so much for this project!And thanks for testing it!I'm running a rootless container using pasta. Everything works great but after a while (anything from minutes to hours) I see the error "Failed to open tun socket in namespace" in my systemd logs, and my container loses access to the internet.That happens when pasta detects an issue with the tap file descriptor (error or closure reported by the kernel, or failed read), so it closes it and tries to open it again. There are two issues actually: 1. the problem with the tap device causing this and 2. the fact that pasta fails to close and reopen the file descriptor.Do you happen to have any idea how I would go about debugging this? Thanks a lot in advance :) PS: I'm running pasta from podman with arguments --map-gw,--dns,<my-dns>,-i,wlan0,--outbound-if4,wireguard0,--outbound-if6,wireguard0,--config-netLet's try to debug issue 1. first: can you pass -d (--debug) and -l (--log-file) here, then check the lines at the end, when pasta terminates? You might want to play with --log-size too if there's a lot of activity. -- Stefano
