Hi,

regarding to Rut300 iperf3 Segmentation fault still
seams not be fixed on my RUT951 with latest Firmware RUT9M_R_00.07.15

Are there any updates?

2

question for you - did you try run it as a client or a server ?

your example was just trying to run it without any args, which is a bit weird.

it needs args, for example to run it as a server/daemon:

/usr/local/usr/bin/iperf3 -s -D

3

yes, sure
iperf3 -s and with full path as you wrote end in segmentation fault

4

damn, anything else on the system segfaulting ? did you remove/re-add iperf ?

5

it may be worth sha256sum ing the iperf3 file - also check the size with ls -la

I recognise your build might be different but here are my results:

root@RUTM52:~# sha256sum /usr/local/usr/bin/iperf3
a3a35e9660dbfb6234b805aa4d0eb7a739112a9f1018c7e317bee390618653ab /usr/local/usr/bin/iperf3
root@RUTM52:~# ls -lah /usr/local/usr/bin/iperf3
-rwxr-xr-x 1 root root 8.0K Jun 4 12:34 /usr/local/usr/bin/iperf3
root@RUTM52:~# uname -a
Linux RUTM52 6.6.87 #0 SMP Wed Jun 4 10:34:44 2025 mips GNU/Linux
