Re: [owl-users] Network unreachable from inside Owl CT

Thank you GM,

The problem solved after running  '/sbin/route add default venet0' inside
the Container:

Sample output:

sub!root:~# ping 195.42.179.202
connect: Network is unreachable
sub!root:~# route -n

64 bytes from 195.42.179.202: icmp_seq=1 ttl=41 time=325 ms


FYI, there is /etc/vz/dists/owl.conf (owned by centos package
vzctl-3.0.23-1) on HN contains:

ADD_IP=redhat-7.x_add_ip.sh
DEL_IP=redhat-del_ip.sh
SET_HOSTNAME=redhat-set_hostname.sh
SET_DNS=set_dns.sh
SET_USERPASS=set_userpass.sh
SET_UGID_QUOTA=set_ugid_quota.sh
POST_CREATE=postcreate.sh

The question now is why Container using OpenVZ official pre-created
templates didn't need this manual routing table manipulation?
