[j0nne]

running ping -T tsonly [destination] returns the following error:

ping: ts option: invalid argument

according to the man page for ping, this should work and works in Ubuntu

Which build number of Windows?

@fpqc I can reproduce this issue on Version 1607 (OS Build 14393.187) (Release Preview / Slow).

See the strace for ping -T tsonly example.com in the gist.

@j0nne Thanks for reporting the issue and @wizardist for the trace. From the strace, it looks like the -T tsonly option uses the IPPROTO_IP\IP_OPTIONS, which is currently not implemented in WSL, but something we are already tracking.
setsockopt(3, SOL_IP, IP_OPTIONS, "D(\5\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 40) = -1 EINVAL (Invalid argument) setsockopt(3, SOL_IP, IP_OPTIONS, "D(\5\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 40) = -1 EINVAL (Invalid argument)

Just an update that support for IP_OPTIONS was added in 16176, but it does not fully unblock ping -T yet. Now it errors out with Invalid timestamp type.

This issue was fixed. Needs to close.
