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 ===========
============= see script at the bottom of: http://www.bufferbloat.net/projects/cerowrt/wiki/IPv6_Tunnel

root@cerowrt:/tmp# sh tunnel.sh
Downloading http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.10.18-1/packages/Packages.gz.
Updated list of available packages in /var/opkg-lists/vancouver.
Package 6in4 (14-1) installed in root is up to date.
Setting up HE.net tunnel
Restarting network... "Device busy (-16)" messages are OK.
Restarting firewall...
Error: Failed to connect to ubus
Done. You should restart the router now to make these take effect.

============== 2) Restarting the firewall from the command line =============
