= Openstack OVH 전용 서버 네트워킹 = ![ ](httpswww.redditstatic.com/desktop2x/img/renderTimingPixel.png) 안녕하세요 여러분, 저는 OVH에서 전용 서버와 /27 서브넷을 주문했습니다. Openstack(가장 중요한 구성 요소 포함)을 설치했습니다. /27 서브넷을 서버에 연결했으며 "eno1"인터페이스에 할당된 5.5.5.128도 핑할 수 있습니다. (5.5.5.는 자리 표시자일 뿐입니다) 문제는 경로가 잘못되었을 수 있기 때문에 다른 모든 IP 주소에 도달할 수 없다는 것입니다. 이것이 내 서버의 경로 테이블입니다. root@controller route 커널 IP 라우팅 테이블 대상 게이트웨이 Genmask 플래그 메트릭 참조 사용 Iface 기본값 ovh-gateway-ip 0.0.0.0 UG 10brqf535e9d2-5d server-main-ip 0.0.0.0 255.255.255.0 U brqf535e9d2-5d 5.5.5.128 0.0.0.0 255.255.255.224 유 brqf535e9d2-5d 192.168.122.0 0.0.0.0 255.255.255.0 유 virbr0 서버 기본 IP의 /24 서브넷 마스크가 정확합니다. /32가 아닌 이유를 알겠습니다. 안타깝게도 VM을 배치하려는 네트워크 경로가 작동하지 않습니다. 그 안에 있는 IP에 연결할 수 없습니다. 외부에서나 컨트롤러 자체에서가 아닙니다. "5.5.5.128/27"의 게이트웨이 IP를 OVH 게이트웨이 IP(기본 경로로 사용 중임), 서버 기본 IP 및 5.5.5.128로 설정하려고 시도했지만 아무 것도 작동하지 않습니다. 혹시 같은 문제를 겪으셨거나 해결책을 아시는 분 계신가요? 도와주셔서 감사합니다! 편집: 내 ifconfig 출력: root@controller ifconfig brq70238470-59: flags=4163,BROADCAST,RUNNING,MULTICAST> mtu 1450 ether 96:76:bc:b7:29:b5 txqueuelen 1000 (Ethernet) RX packets 103 bytes 4852 (4.8 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 brqf535e9d2-5d: flags=4163,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet main-ip netmask 255.255.255.0 broadcast xxx inet6 main-ipv6 prefixlen 56 scopeid 0x0 inet6 xx prefixlen 64 scopeid 0x20 ethertxqueuelen 1000 (Ethernet) RX packets 83655 bytes 3800864 (3.8 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 129123 bytes 8067301 (8.0 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 eno1: flags=4163,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 xx prefixlen 64 scopeid 0x20 ether d0:50:99:da:39:ac txqueuelen 1000 (Ethernet) RX packets 85212 bytes 5905226 (5.9 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 131955 bytes 8233407 (8.2 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 499119 bytes 146251170 (146.2 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 499119 bytes 146251170 (146.2 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 tap3166097e-73: flags=4163,BROADCAST,RUNNING,MULTICAST> mtu 1450 ether 96:76:bc:b7:29:b5 txqueuelen 1000 (Ethernet) RX packets 12 bytes 2284 (2.2 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 102 bytes 6116 (6.1 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 tap4b8dc5a7-f5: flags=4163,BROADCAST,RUNNING,MULTICAST> mtu 1500 ethertxqueuelen 1000 (Ethernet) RX packets 7 bytes 702 (702.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 91823 bytes 4385443 (4.3 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 tapc2ba003a-21: flags=4163,BROADCAST,RUNNING,MULTICAST> mtu 1450 inet6 fe80::fc16:3eff:fe03:28a3 prefixlen 64 scopeid 0x20 ether fe:16:3e:03:28:a3 txqueuelen 1000 (Ethernet) RX packets 102 bytes 6116 (6.1 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 15 bytes 2378 (2.3 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 virbr0: flags=4099,BROADCAST,MULTICAST> mtu 1500 inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255 ether 52:54:00:de:85:70 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 vxlan-53: flags=4163,BROADCAST,RUNNING,MULTICAST> mtu 1450 ether ea:e4:58:8e:bc:d8 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 103 overruns 0 carrier 0 collisions 0 Its a bit strange, ifconfig doesnt show me my 5.5.5.128/27 here. # ip a12: brqf535e9d2-5d: ,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/etherbrd ff:ff:ff:ff:ff:ff inet main-ip/24 brd xxx.255 scope global brqf535e9d2-5d valid_lft forever preferred_lft forever inet 5.5.5.128/27 brd 5.5.5.159 scope global brqf535e9d2-5d valid_lft forever preferred_lft forever inet6 xxx/56 scope global valid_lft forever preferred_lft forever inet6 xxx/64 scope link valid_lft forever preferred_lft forever ![ ](httpswww.redditstatic.com/desktop2x/img/renderTimingPixel.png) Hi, Try to list all the interfaces and taps connected to the bridge brqf535e9d2-5d with the command "brctl show". 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
