WAN_DHCP6 or WAN_SLAAC pending/Unknown

dh377 · Nov 14, 2023, 6:54 AM

This is quite an old bug on Comcast/Xfinity. Especially when using XFINITY/xfinitywifi as WAN, those do not propagate IPv6 Prefix through DHCP/RA, and dhcp6c or rtsold could not properly run gateway setup scripts internally. This could be fixed with making it fetch a default gateway address anyway through netstat.

@dh377 what version are your running?

That problem was solved in 23.05.1

dh377 · Nov 14, 2023, 5:27 PM

@maverickws CE 2.7.0. Do dhcp6c or rtsold correctly execute scripts which result in /tmp/<interface>_routerv6 and /tmp/<interface>_defaultgwv6?

@dh377 I had that problem on 23.01 and some other users as well, I believe you'll find this whole topic about it interesting.

@maverickws my script has CRLF line ends (#!/bin/sh^M). It's prevent the script to run.

@dh377 the ^M is a DOS/Windows line ending.
Did you edit that file on windows or something?

The original file for sure doesn't have them as we all are using it without issues.

Either use a file editor and save the file with unix format line endings or just get a source copy of the file, can't help you any further as that is a local issue.
