ipv6 broken: radvd: can't join ipv6-allrouters on <interface>

yon 0

I tried to restart the service yesterday and did not solve the problem. Restart the system to work.I have problems after about 20 hours of running.

kiokoman

well i dont know how to solve the problem, you have 2 options, wait for the staff to solve it or go back to 2.4.4

@yon-0 a restart using the GUI doesn't work, you need to stop the service, wait 5 seconds and start the service.

Or script it using cron, as suggested.

ye, this is work. but we still need waiting for admin fix it.

Just tired enabling RA again and still having issues with log spam and dropouts.

My ISP disabled Ipv6 last month, so I am using HE tunnel now.
Same problem as TS mentioned — SPAM and drops after some hours.

Irata

Interesting, I'm using an HE tunnel too

@Irata
I am not sure that my ISP native Ipv6 have been working, so I don't think it's HE related. I am parsing tons of syslog messages now, let me see, if I find something, I'll let you know.

maverick_slo

I have native with same issues...

strangegopher

my isp has ipv6, no tunnel. i don't think that matters. at this point i think everyone is affected.

kiokoman

nope, nothing to do with tunnel, it's radvd that is broken

According to my logs there was no any problem with ISP Ipv6, but it was special case — configured to track PPPoE interface and used stateless DHCP router mode, DHCPv6 server not enabled.

i put here a workaround that seems to work for me

[2.5.0-DEVELOPMENT][root@pfSense.localdomain]/root: crontab -l
@hourly killall radvd && sleep 5 && /usr/local/sbin/radvd -p /var/run/radvd.pid -C /var/etc/radvd.conf -m syslog

Sorry for dumb question but where does it stored? I have executed this command, but I don't see anything similar in cron package. I can not also find any modified file on a system.

kiokoman

contrab -l (list)
crontab -e (edit)
from the terminal
you need to edit crontab with

crontab -e

then copy/past what i have in my crontab

@hourly killall radvd && sleep 5 && /usr/local/sbin/radvd -p /var/run/radvd.pid -C /var/etc/radvd.conf -m syslog

or you can install the cron pkg available in the gui and add

killall radvd && sleep 5 && /usr/local/sbin/radvd -p /var/run/radvd.pid -C /var/etc/radvd.conf -m syslog

as command line
what does it do: kill radvd & wait 5 seconds & restart radvd

Thank you for clarification. Okay, in that case, then, my bad. I just was too lazy to run it from terminal and used GUI command prompt, stupid me... It does not work that way.

Since I have cron GUI package installed, I'll try to make it over GUI.

Does anybody else with HE tunnel have those messages in the log?

I don't see any side effect, looks like gateway monitor works with no problem at least in GUI it shows correct data.

kiokoman

nope, never

kiokoman

anyway it seems like we are not alone with this

@kiokoman
Have seen this on the previous week, but it does not look promising. No answers from developer, no code changes, nothing.

Wait a minute....
We all rely on 1 person alone?
