= Openstack OVH Dedicated Server Networking = ![ ](httpswww.redditstatic.com/desktop2x/img/renderTimingPixel.png) Hello semua, saya telah memesan pelayan khusus dan subnet /27 daripada OVH. Saya memasang Openstack (dengan komponen yang paling penting) padanya. Saya telah menyambungkan subnet /27 ke pelayan dan juga boleh ping 5.5.5.128, yang diberikan kepada antara muka "eno1". (5.5.5. hanyalah pemegang tempat) Masalahnya ialah semua alamat IP lain tidak dapat dicapai kerana laluan mungkin salah. Itulah jadual laluan pelayan saya: root@controller route Jadual penghalaan IP Kernel Destination Gateway Genmask Flags Metrik Ref Gunakan Iface lalai ovh-gateway-ip 0.0.0.0 UG 10brqf535e9d2-5d server-main-ip 0.0.0.0 255.255.255.0 U brqd25.0.0 U brqd2535d 255.255.255.224 U brqf535e9d2-5d 192.168.122.0 0.0.0.0 255.255.255.0 U virbr0 Subnet mask /24 untuk IP utama pelayan adalah betul. Idk mengapa ia bukan a /32 Malangnya, laluan ke rangkaian yang saya ingin letakkan VM tidak berfungsi. Saya tidak dapat mencapai sebarang IP di dalamnya. Bukan dari luar mahupun dari pengawal itu sendiri. Saya cuba menetapkan IP get laluan untuk "5.5.5.128/27"kepada IP get laluan OVH (Saya menggunakan untuk laluan lalai), IP utama Pelayan dan juga 5.5.5.128, tetapi tiada apa yang berfungsi. Adakah sesiapa di antara anda pernah mengalami masalah yang sama atau tahu penyelesaiannya? Terima kasih atas bantuan anda!

You can see wich network namespace is connected to the tap interface doing "ip a" under link netns. Then try to stablish communication in the subnet from the network namespace. "ip netns exec [netns connected to the tap] ip a" This way you can see if you can stablish connection to instances running in compute nodes in the subnet 5.5.5.128/27 Hi, thanks for your reply. The brctl show returns me this: root@controller brctl show bridge name bridge id STP enabled interfaces brq70238470-59 8000.1ed5e9a9e7c0 no tap2a631157-e2 tap3166097e-73 tapc2ba003a-21 tapeefe5e6c-2d vxlan-53 brqf535e9d2-5d 8000.b65368642388 no eno1 tap4b8dc5a7-f5 tapa2486984-d4 virbr0 8000.525400de8570 yes Could you explain how and where I can find the "network namespace" You can see wich network namespace is connected to the tap interface doing "ip a" under link netns. I can't find it .128 looks like a network address. you should use 129-158 for host and one ip should be the gw == About Community == Members Online
