I think downing eth0 was the right track, but I believe the physical interface does need to be up in order for the virtual interface to use it. Perhaps if you de-configure eth0, e.g. [root@box ~]# ifconfig eth0 0.0.0.0 so that packets on the 192.168.80.* subnet have only the VLAN interface to go out on... ________________________________ From: vlan-bounces@xxxxxxxxxxxxxxx [mailto:vlan-bounces@xxxxxxxxxxxxxxx] On Behalf Of Rui Cristo Sent: Wednesday, April 26, 2006 4:31 PM To: vlan@xxxxxxxxxxxxxxx Subject: [VLAN] Vlan is inactive Hi all, I`m trying to create a simple VLAN and make the traffic from a socket go through this interface and leave the device tagged. Here is the configuration: ----------------------------------------------------------------------------------------------- # modprobe 8021q # vconfig add eth0 10 # ifconfig eth0 10 192.168.80.149 up # ifconfig eth0 Link encap:Ethernet HWaddr 00:11:25:88:AB:12 inet addr:192.168.80.143 Bcast:192.168.80.255 Mask:255.255.255.0 inet6 addr: fe80::211:25ff:fe88:ab12/64 Scope:Link UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14474 errors:853 dropped:0 overruns:0 frame:853 TX packets:19960 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4931508 (4.7 Mb) TX bytes:19059455 (18.1 Mb) eth0.10 Link encap:Ethernet HWaddr 00:11:25:88:AB:12 inet addr:192.168.80.149 Bcast:192.168.80.255 Mask:255.255.255.0 inet6 addr: fe80::211:25ff:fe88:ab12/64 Scope:Link UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:484 (484.0 b) lo Link encap:Local Loopback ... ----------------------------------------------------------------------------------------------- -> I want to bind this VLAN to a socket, to send packets tagged through it. I bind it with IP: ----------------------------------------------------------------------------------------------- myaddr.sin_family = AF_INET; myaddr.sin_port = htonl(PORT); inet_aton("192.168.80.149", &myaddr.sin_addr.s_addr); if( (bind(sockfd, (struct sockaddr*)&myaddr, sizeof(struct sockaddr))) < 0 ) { printf ("erro bind: %d\n", ret); close(sockfd); exit(-1); } ----------------------------------------------------------------------------------------------- The problem is that the sent packets contain the source address 192.168.80.149 but the traffic is sent only by eth0, the eth0.10 is inactive. Even trying to see the packets with ethereal in Capture->Interfaces the eth0.10 seems to be inactive. How can I send packets through eth0.10 to "TAG" the traffic. I have already tried to "DOWN" eth0 but doesn`t work (and the computer crashes). Thanks ________________________________ Yahoo! doce lar.
