Hi Sandy, Thanks! Curious. Do you have any other interfaces? ifconfig -a should show them all including loopback. What is puzzling me is that it should not even attempt to use IPv6 to reach a global address when it only has a link-local address. It should gracefully fall back to IPv4 (as per RFC 6724 or RFC 3484 depending on the kernel version). Since you have an IPv4 address and I assume an

Diagnosing IPv6 routing
I just got 50 Mbps symmetric fiber from AT&T and it includes a /56 of IPv6 addresses, replacing a much slower ADSL line. I never tried to get IPv6 working on the old connection. I'm using CentOS 7 as a gateway and it's worked great for several versions for IPv4. I'm not seeing any IPv6 default route on the WAN interface. I suspect I'm not getting route announcements. I

Ifconfig ipv6:permission denied.
Hi! I installed CentOS 7 today, it's a minimal install, so it didn't have ifconfig command. So I installed net-tools, however I can't add ipv6 address to it. # ifconfig enp0s3 add fc00::1002/124 SIOCSIFADDR: Permission denied. Yes, I'm running as root. CentOS is running in a Qemu instance with e1000 ethernet card.

Suddenly getting lots of "Unable to send packet: Address Family mismatch between source/destination" but ONLY on 1 of 2 VPSs in same datacentre.
Two VPSs. Identical setups with the exception of the extension. Same version of everything, Asterisk 14.1, Ubuntu 16.10, same firewall rules and so on - box 2 was cloned from box 1. Both VPSs run in the same datacentre. Suddenly, after weeks of OK, I'm getting lots of this on ONE box only: [Nov 4 21:23:04] NOTICE[1468]: res_hep.c:466 hep_queue_cb: Unable to send packet: Address Family

Centos 6 - disabling IPv6 addressing
Sorry - that should be sysctl -w net.ipv6.conf.all.accept_ra=0 to disable that, not 1.

Hi Sandy, Please can you provide the output from an *i**fconfig -a* command? This should give an idea of what is going on. Turning off IPv6 will not be necessary if you can find the actual cause of the problem. You would not get this error message if you only have a link local address configured on your interface. You must have some form of global address. Also, the IPv6 address is that of

Re: guestfish Remote Images IPv6 Support
Unfortunately I do need to use the address explicitly as opposed to hostnames because the source of the data fed here is Ceph's monmap which returns the addresses explicitly. I've tried all the common ways to escape the : in the v6 address to no avail.  I definitely agree that the problem looks to be it parsing the colons as if the port comes next and then everything after that is
