...e requires using different vlan IDs. suffice it to say I need bridges to connect a few different vlans that should all be one but can''t be because of firmware constraints. so my first step is to get shorewall to know about bridges. I convert my existing config to a bunch of bridges lan0 becomes a member of br-lan0, lan1 becomes a member of br-lan1, and shorewall gets edited. interfaces and routestopped, I prefix lan0 and lan1 with br- and I restart shorewall (sudo shorewall safe-restart). This is a ubuntu system, and far as I can tell everything is right. I''m usin...

Hello... Im trying to setup HTB to allow me to shape traffic from two upstreams that meets on single lan0 interface. I prefer to use HTB qdisc within HTB root qdisc for cleaner rules design. Seems that it doesnt work at all. tc -s class show doesnt show any traffic on other classes attached to HTB qdisc. Linux 2.6.20.7 iproute-2.6.20-070313 Weird thing is that tc -s class show that 1: and 2: are bot...

Hello to everyone, Here is the situation: [LAN1]---[eth3]/----------\ | LinuxBR |[eth2]---[LAN0]---[linuxGW]---[internet] [LAN2]---[eth4]\----------/ Whole LAN is in subnet 10.0.0.0/24. So I need: LAN0, LAN1, LAN2 could not see each other. LAN0, LAN1, LAN2 is in same subnet (10.0.0.0/24). All LANs have to get only internet. How can I configure LinuxBR to do so? Do I have to do o...

Thanks for this answer. As I understood, for example if parameter bind interfaces only = yes is and interfaces = lan0 (192.168.0.254) is and if broadcast packet goes from 95.95.95.14 such packet will be dropped (in other words) ? Am I right ? And other thing. Why is 192.168.0.255 (network broadcast) opened for ? May be exact such address (network broadcast) is inbtended for receiving broadcasts ? Within exact su...

...sting. I think the problem is in the fact it is configured to listen on several interfaces. These interfaces are virtual (I'm using vlan and 802.1q). There are several subnets (named lan_xxx), all nated by a FreeBSD box on the outside (the outside is a private network too, let's name it lan0. The PDC has one interface for each subnets, even for lan0. But isn't there a problem if the PDC announce himself with the same name on all the vlans, as the carbone is only delcared for lan0 ? Should I not use virtual servers with several smb.conf for each vlans, where the PDC could be nam...

I have Samba4 4.1.14 (built from sources) installed at Ubuntu 14.04 LTS x32 and acting as Standalone server at the time. Here are 3 faces at Ubuntu: lo, lan and wan.

...consider "up" - i.e. have an IP address. ens3 doesn't get it's IP address until much later. This works for Carlos though because he doesn't need an IP address - just the device existing. I have no idea how it worked for the stackexchange poster. Apparently because "lan0" is a virtual device as well ("sys-devices-virtual-net-lan0") that they need, not a more "physical" device like "net-devices-ens3", and it gets an IP address at the same time as creation. I've been dealing with issues like this for a while - systems with...

...tion to what is loaded along the > way. A major problem with my system. I'm sorry for perhaps asking something entirely obvious, but have you tried: kernel-dir $ rsync -avr tools/testing/selftests/ root@$board:selftests/ board $ cd selftests/drivers/net/dsa/ board $ ./bridge_locked_port.sh lan0 lan1 lan2 lan3 ? This is how I always run them, and it worked fine with both Debian (where it's easy to add missing packages to the rootfs) or with a more embedded-oriented Buildroot.

I need to change the host name on a test server, and in the past when I used hostname to change the hostname, it did not seem to change it everywhere. I really don't want to do a rebuild just yet, but I have to feel confident that hostname is really changed (reboot is not too much of an issue). What is the recommened practice? Other than get it right the first time.
