Hi!
Since I have no fr**king clue what could the problem be, I'm trying on
this list :)
I have a native IPv6 connection on my Desktop behind my router.
curl -v -6 http://anyurl.foo
doesn't work, the connection just times out SOMETIMES (when there is a
problem, tcpdump on the router says I doesn't even receive any packets
back, ip6tables is empty on the Desktop).. BUT a:
curl -v -6 --head http://anyurl.foo
is perfectly working. See my ping from my Desktop:
root@server:~# ping6 -c 10 -s 2000 -M do IPV6ADDRESSOFANYURL.FOO
PING IPV6ADDRESSOFANYURL.FOO(IPV6ADDRESSOFANYURL.FOO)
2000 data bytes From IPV6ADDRESSOFSOMEGATEWAY icmp_seq=1 Packet too big:
mtu=1452
2008 bytes from IPV6ADDRESSOFANYURL.FOO: icmp_seq=2 ttl=54 time=82.5 ms
2008 bytes from IPV6ADDRESSOFANYURL.FOO: icmp_seq=3 ttl=54 time=82.4 ms
soo... it couldn't be an MTU problem.. since the ping is ok.. (?) ->
there are icmp echo replies..
WHY does the connection "randomly gets bad"? (so sometimes it works,
sometimes not, the "anyurl" is ex.: youtube, facebook, and it works from
other places via IPv6 when it doesn't work behind my Desktop..)
Any help would be appreciated.. a keyword to what to google for or sth.
IMHO the problem isn't on my Desktop or on the remote site (other
Desktops behind the router are sometimes bad).
Maybe between somewhere, but how can I know which GW is bad that are
shown in a traceroute?
(xxx is my original IPv6 addres, just censored)

The "Permission denied" appears even when trying with root
