'setting SO_TIMESTAMPNS option: Protocol not available' error fping 5.1-1 on Ubuntu 22.04 over WSL1

[grafias3787]

As the title mentioned we have Ubuntu 22.04 running over WSL1 on Windows Server 2019 and face the below error when using the fping application. Of cource the IP 192.168.1.1 is reachable from the server. The issue was replicated on three different servers with the same specs and versions.

root@server: fping 192.168.1.1
setting SO_TIMESTAMNS option: Protocol not available
setting SO_TIMESTAMNS option (IPv6): Protocol not available
192.168.1.1 is unreachable

We have tested also version 5.0-1 with the same result.
Finally we have downgraded to 4.2-1 and it worked normally.

[gsnw]

Can you please execute the following two commands inside your WSL1 Ubuntu enviroment and send back the output?
I hope gcc is installed.

Command-1
uname -a

Command-2
gcc -dM -E - </dev/null

Good day, below the results

[gsnw]

Can you please run the following commands? These commands look for the string SO_TIMESTAMPNS in all socket.h and types.h files under /usr/include.

cd /usr/include
find ./ -name socket.h -print0 | xargs -0 grep SO_TIMESTAMPNS
find ./ -name types.h -print0 | xargs -0 grep SO_TIMESTAMPNS

[grafias3787]

Should I run the commands having fping 5.1 installed or it doesn't matter? I have on the server running with version 4.2-1 because it is production server.

[gsnw]

Just run it, fping does not need to be installed

The better "really user-friendly" UX here, given that SO_TIMESTAMP* often require privileges not available (containers, outdated security module/syscall filters configuration, etc) would be to detect which one can be used at runtime, if any, and just do it. And be silent about it unless in debug or very-verbose mode, I guess...

[kaspergrubbe]

I wanted to run fping inside of my Docker container and I get the same permission issue. I don't have enough unix-fu to know which permission or capability to give my Docker container to use SO_TIMESTAMP*.

[gsnw]

Fixed with pull request #279

[auerswal]

Hi @sergiossl,

could you describe the problem in more detail, perhaps copy & paste the output of fping from the terminal?

The original report comprises two issues:

1. There are error messages pertaining to the socket option SO_TIMESTAMPNS.
2. The target host is reported as unreachable although it is reachable.

The first issue was addressed in the development version of fping (but not yet in an fping release) via pull request #279, in that now a fallback to SO_TIMESTAMP is tried if using SO_TIMESTAMPNS fails, and a slightly different error message is produced only if both fail. As such I would at least expect there to be a different error message instead of exactly the same problem. It is also important to know if fping gives a wrong result, i.e., reports a reachable target as unreachable.

(Please note that I do not have Windows and thus cannot reproduce the problem(s), neither can I verify any potential fixes.)

Thanks,
Erik

@sergiossl Please open a separate issue and describe the problem. I am closing this one as fixed since #279 has been merged.
