Re: 'struct ifnet' question!
Thanks, event handlers looks very trivial to implement. My thoughts was: userland read rules and check if interface exist with: 'if_nametoindex(interface)' call. kernel stores rules without any knowledge about interface name or direction, because I use seperate decision tree for every interface + direction pair. When module got departure event, all rules are flushed from in/out decision tree: flush_rules(decision_tree[ifp->if_index]->out); flush_rules(decision_tree[ifp->if_index]->in); because if interface is gone, rules are not valid: # ifconfig vlan0 create if_findindex() returns index 6 # load rules with '... in on vlan0 ...' kernel store rules in 'decision_tree[6]->in' # ifconfig vlan0 destory here we must flush all vlan0 rules # ifconfig gif0 create gif0 got index 6 if we don't flush old rules, gif0 will use vlan0 rules because index is reused... And here is the problem: If i watch departure events, interface renaming feature will flush walid rules: case SIOCSIFNAME: ... EVENTHANDLER_INVOKE(ifnet_departure_event, ifp); ... change if_xname ... EVENTHANDLER_INVOKE(ifnet_arrival_event, ifp); how about another event? ;) EVENTHANDLER_INVOKE(ifnet_rename_event, ifp->ifx_name, new_name); strlcpy(ifp->if_xname, new_name, sizeof(ifp->if_xname)); > The other (big) problem in this field is, how to handle yet unknown interfaces > (e.g. USB/Cardbus/ppp/tun/...). What is about usb/cardbus/... interfaces? Don't they also call ether_ifattach()/if_attach()? -- Artis On Thu, Apr 29, 2004 at 02:22:47PM +0200, Max Laier wrote: > Yes there is, in -current you will find some eventhandlers (in if_var.h and > if_clone.h) which allow you to get a notification when an interface arrives > or leaves.

Dlink DSL router doesn't like FreeBSD
I'm trying to make work a D-Link 504T DSL router/switch with FreeBSD 5.2.1-RELEASE-p6. I've already realised that IPv6 is not supported by the router so I compiled an IPv4-only kernel and got to work DNS, HTTP, and FTP. My problem is that ssh and telnet don't work. I get as far as the Password prompt, I type it in, and then ssh freezes for a couple of minutes until it probably goes in timeout and gives up. The D-Link help desk is useless; the only thing they suggested was to return the router to where I bought it. I've anyhow the impression that the problem might not completely be the router's fault. In fact I plugged a Windoze machine, installed PuTTY, and ssh seems to work flawlessly. What am I missing here?

I'd try two things: 1) ssh -vvv [EMAIL PROTECTED] 2) tcpdump -vv (while trying to connect by telnet or ssh) You might have a chance to see where problems occur.

Re: Dlink DSL router doesn't like FreeBSD
Try connection to the router via SSHv1 protocol and without X11 forwarding. I had similar problems with Cisco routers with old Cisco IOS. They liked only SSH connections via SSHv1 and without X11 forwarding.

Transparent Bridging Admin Interface
Hi folks, I was searching the through the archives and found this question which seams to be describing a similar problem I am having, I did not find a reply or answer to it though. So I would like to ask the question again as it seams to very close to mine and I would imagine it must be resolveable, probably through a simple configuration or patch See the link below for the original post. http://lists.freebsd.org/pipermail/freebsd-net/2003-December/002109.html I have set up Transparent Bridging and IPFW on a server by compiling support into the Kernel as described in the FreeBSD handbook and other FreeBSD tutorials, no frills just the basics 2 interfaces, no IPs, passing traffic with the firewall wide open by default. I configured the machine over ssh before I stuck it on the network via a third interface that has an IP from the LAN the machine is bridging. When I put the bridge onto the network, it works perfectly, passing all packets both ways through the open firewall, but the third interface, the admin one with an ip on my network stops working just like describe in the original post Oh yea... FreeBSD 5.2.1 P4 1.4ghz 512Ram 2x3com (bridge) nics 1xrealtek (admin interface w/ ip) It must be some sort of logical loop bug!!!
