I’m correctly get following error. After searching about this issue, correct me if i’m wrong, I believe that adding/configuring IPv6 should solve the problem.

PHP Fatal error:  Uncaught CurlException: 7: Failed to connect to 2a03:2880:10:8f02:face:b00c:0:26: Network is unreachable\n  thrown in /var/www/vhosts/facedex.net/httpdocs/fb/apps/seemyfuture/src/base_facebook.php on line 886

The problem is I dont know the right way to add it. There seems to have may methods. http://tldp.org/HOWTO/Linux+IPv6-HOWTO/x1035.html#AEN1044 http://unix.stackexchange.com/questions/34093/static-ipv4-ipv6-configuration-on-centos-6-2

My netstat show this. Shell doesnt recogize -rn6 though.It shows invalid option — 6

netstat -rn

FYI: I’m using Centos 5.7.

Thank you a lot in advance.

  1. I’m assuming that you don’t actually have IPv6 connectivity, in which case you probably want to disable IPv6.

  2. Short of globally disabling ipv6 you can try the –ipv4 argument to curl. I think that is what I used in a similar situation.

  3. You can’t just arbitrarily configure IPv6. You need to get IPv6 from your ISP, or create a tunnel with Hurricane Electric, Gogo6 or similar.
