RUT955 Tailscale

[deke]

Hi, we have a RUT955 running with firmware RUT9_R_00.07.04.2.

We are having issues when trying to install Tailscale. The router is saying I do not have enough space in /overlay. Is there a solution to this without using an external USB/SD?

I’ve also tried this

Hello,

Unfortunately, not much can be done. I am not sure, but it is possible that there will be slighly more flash memory available on RUT955 on older FW. You can try 7.3.4 or 7.02.7 FW. However, even if it will fit, it is likely that it will take up all your free flash and you wont be able to install any other packages. I would suggest expanding the memory with USB drive (link here).

Kind Regards,

You can run “official” openwrt on the RUT955. And only install required packages. Last not least: Cross-compile tailscale_COMBINED and install it (COMBINED: tailscale+tailscaled within one multi-call binary. Like busybox.) Simply removing already installed packages does NOT FREE used flash.
