[Cerowrt-devel] CeroWrt 3.10.18-1 odd firewall warnings

[Richard E. Brown]

When I was trying to set up the Hurricane Electric 6in4 tunnel, I got two sets of warnings from CeroWrt 3.10.18-1.

1) I used the tunnel.sh script (see URL below) to set up my tunnel. I got the first set of output. Note the “Error: Failed to connect to ubus” message. Is this OK? (The tunnel did come up after restarting the router.)

2) I then re-ran the firewall restart command (see second set of output) and saw a number of warnings. Any problems/surprises here?

Best,

Rich

============= 1) Restarting the firewall from the script that sets up the HE.net 6in4 tunnel ===========

Done. You should restart the router now to make these take effect.
