Hi Johan,

By default OpenWrt comes with busybox-nc (the busybox implementation of netcat) which does not support server mode. However, can install GNU netcat.
Please check if the Netcat package exits in the RUT240 or not. Go to CLI and issue the below command:

opkg list-installed

if you cannot see the package, please install it using command:

opkg install netcat

If the package is already there try to remove it and then reinstall it again.

Hi,

opkg install netcat did not work but the command ns seems to be working again:

[email protected]:~# nc

BusyBox v1.33.1 (2021-08-31 22:20:08 UTC) multi-call binary.

Usage: nc [IPADDR PORT]

Open a pipe to IP:PORT

Thanks for your support.

Hi Johan,

In case, if you face this issue in the future. Try to flash the firmware again. Download the firmware file here and please click on the link below on how to flash the firmware:

Note: It is recommended only in case if you cannot run nc at all.
