Hi, I am on 14-CUREENT (6fa88a4ad35e from April) and I recently started to experience something which looks like: ping6 -n ff02::1%wlan0 works ping6 -n host works but ssh to host hangs. Given this seemed to be periodic-ish and I only always notice way after the facts I started to poke around and found: ndp -P ndp -R rtsol wlan0 fixes things. I've seen similar problems with NDP vs. routing table updates and another rtsol call would not bring back the default route unless ndp -R was run before and I wonder if these are connected. Both have become a bit annoying problems on a day-to-day IPv6-only usage for me that I had never experienced like this (in the last decade) before. If anyone has ideas and saves me from spending too many hours digging into this now I'd appreciate. /bz -- Bjoern A. Zeeb r15:7
