What I've seen (from "tcpdump -i ng0") is that broadcast packets are sent through the tunnel, but generally nobody receives them. However, there is at least a way to get a local daemon to see the broadcasts, using the loopback device... Supposing your mpd segment is x.y.z.0/24, this should work: ifconfig lo0 add x.y.z.4 netmask 0xffffff00 # a unicast addr ifconfig lo0 add x.y.z.255 netmask 0xffffff00 # the broadcast addr Now a daemon listening on x.y.z.4 should get the broadcasts. I've got the Samba nmbd running this way. - JD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Sun Nov 24 23: 9:32 2002 Delivered-To: freebsd-net@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 1246B37B404; Sun, 24 Nov 2002 23:09:31 -0800 (PST) Received: from hotmail.com (f69.law15.hotmail.com [64.4.23.69]) by mx1.FreeBSD.org (Postfix) with ESMTP id 3576C43E91; Sun, 24 Nov 2002 23:09:29 -0800 (PST) (envelope-from soheil_hh@hotmail.com) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Sun, 24 Nov 2002 23:09:29 -0800 Received: from 81.31.160.37 by lw15fd.law15.hotmail.msn.com with HTTP; Mon, 25 Nov 2002 07:09:28 GMT X-Originating-IP: [81.31.160.37] From: "soheil soheil" To: A.Nepomnyaschih@chartpilot.ru Cc: freebsd-net@freebsd.org Subject: RE: Error on installing FreeBSD 4.4 on Dell Inspiron 2650 ( 2.0 GHz ) Date: Mon, 25 Nov 2002 07:09:28 +0000 Mime-Version: 1.0 Content-Type: text/plain; format=flowed Message-ID: X-OriginalArrivalTime: 25 Nov 2002 07:09:29.0112 (UTC) FILETIME=[9878F180:01C29451] Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Hi By the way , It found the atapci0 device atapci0 : ....... at ata0 and pci0 then it founds the ata0 and found the device type and then it cannot found the pci0 pci0 (vendor=8086 .... ) IRQ ... pci0 (vendor=8086 .... ) IRQ ... pci0 (vendor=8086 .... ) IRQ ... it hanges up while to start the installation it never goes to the install menu ....

I personally would do it the Netgraph way, using a setup much like the one in the ng_ether(4) example section, but substituting my own module in place of the ng_tee node, so it does not unconditionally pass the packets, but analyze them first.

My 802.1x implementation is still lacking quite a lot, especially at the user space side. The kernel level stuff is mostly complete. The biggest missing pieces at the kernel side are support for multiple clients in a shared Ethernet, and SMP support so that the code could be included in 5.0-current. On the user level side, there is no support for Radius or Diameter, or for any other EAP protocols but OPIE. OTOH, it should be very easy to write new user level modules, especially client side modules. If I remember correctly, I had some changes in mind for the server side user level library, but I don't remember exactly what. The TODO should tell you something. Having said that, I do intend to continue the work, but just haven't had time. If there is interest, I'd more than happy to help other folks in continuing with the code. (Having a baby at the house keeps me very effectively from having too much spare time, and my job responsibilities have drifted away from FreeBSD.) If you want to start working, don't hesitate sending me e-mail, either CC:ing to the list or privately. Reading the Usenix paper (available on my web pages) probably helps understanding the structure of the code. --Pekka To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Tue Nov 26 5:14:51 2002 Delivered-To: freebsd-net@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 6E9A237B404 for ; Tue, 26 Nov 2002 05:14:48 -0800 (PST) Received: from smtp.completel.fr (smtp.completel.fr [213.244.0.12]) by mx1.FreeBSD.org (Postfix) with ESMTP id 6C7F243E4A for ; Tue, 26 Nov 2002 05:14:37 -0800 (PST) (envelope-from fabien.thomas@netasq.com) Received: from netasq.com (unknown [213.30.137.178]) by smtp.completel.fr (Postfix) with ESMTP id AA66D179D83 for ; Tue, 26 Nov 2002 14:14:25 +0100 (CET) Received: from netasq.com by completel.fr (8.10.1/8.10.1) with ESMTP id gAQDEx223726 for ; Tue, 26 Nov 2002 14:14:59 +0100 (CET) Date: Tue, 26 Nov 2002 14:13:59 +0100 From: Fabien THOMAS X-Mailer: The Bat!

Sigh, I guess TANSTAAFL shows true. I was hoping once the PCB was setup that it could act like some sort of packet attractor. Or in other words, to get the packet stream to play follow the leader on the syn. --don (don@sandvine.com www.sandvine.com) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Tue Nov 26 12:54:26 2002 Delivered-To: freebsd-net@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id D2AA437B401 for ; Tue, 26 Nov 2002 12:54:23 -0800 (PST) Received: from ns1.interbgc.com (mail.interbgc.com [217.9.224.3]) by mx1.FreeBSD.org (Postfix) with SMTP id D5EDD43E9C for ; Tue, 26 Nov 2002 12:54:19 -0800 (PST) (envelope-from misho@interbgc.com) Received: (qmail 63099 invoked by alias); 26 Nov 2002 20:54:02 -0000 Message-ID: <20021126205402.63098.qmail@ns1.interbgc.com> References: <127338536921.20021126141359@netasq.com> In-Reply-To: <127338536921.20021126141359@netasq.com> From: Mihail Balikov To: Fabien THOMAS Cc: freebsd-net@freebsd.org X-Priority: 3 Subject: Re: bpf_tap problem with PKTHDR Date: Tue, 26 Nov 2002 22:54:02 +0200 Mime-Version: 1.0 Content-Type: text/plain; format=flowed; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I found similar problem with bpf flag BIOCSSEESENT.

The question is WHERE are the packets being lost?. Are all the generated packets being aimed at a single session? are they all session startup packets, or data packets on an already set up session? I would suspect that the socket buffer size on the netgraph socket that ppp is using may be too short. you can try increase the buffer size in pppoed.c using int newval; int len; len = sizeof (newval); [...] getsockopt( so, SOL_SOCKET, SO_RCVBUF, &newval, &len); newval *= 4; /* make it 4 times as big */ setsockopt( so, SOL_SOCKET, SO_RCVBUF, &newval, len); This should happen in the function Spawn() probably about if (debug) syslog(LOG_INFO, "Sending CONNECT from .:%s -> %s.%s", ngc.ourhook, ngc.path, ngc.peerhook); if (NgSendMsg(cs, ".:", NGM_GENERIC_COOKIE, NGM_CONNECT, &ngc, sizeof ngc) < 0) { syslog(LOG_ERR, "Cannot CONNECT PPPoE and socket nodes: %m"); _exit(EX_OSERR); } /* HERE */ ========new code /* make the data socket buffer larger */ getsockopt( ds, SOL_SOCKET, SO_RCVBUF, &newval, &len); newval *= 4; /* make it 4 times as big */ setsockopt( ds, SOL_SOCKET, SO_RCVBUF, &newval, len); /* * If we tell the socket node not to LINGER, it will go away when * the last hook is removed. */ if (debug) syslog(LOG_INFO, "Sending NGM_SOCK_CMD_NOLINGER to socket"); if (NgSendMsg(cs, ".:", NGM_SOCKET_COOKIE, NGM_SOCK_CMD_NOLINGER, NULL, 0) < 0) { syslog(LOG_ERR, "Cannot send NGM_SOCK_CMD_NOLINGER: %m"); _exit(EX_OSERR); } > > DHCP performs fine.

It was a firewall problem. I have to had in ipf.rules a pass in quick proto ipv6 from IPV6GATEWAY to MYIPADRESS and a pass out quick proto ipv6 from MYIPADRESS to IPV6GATEWAY. I have to modify the ipf6.rules to (pass in quick all and pass out quick all). I have to use ifconfig gif0 tunnel MYIPADRESS IPV6GATEWAY (like in the handbook) and not ifconfig gif0 giftunnel MYIPADRESS IPV6GATEWAY. Does anybody have a good working ipfilter conf for ipv6 ?

Essentially this would assure that a multihomed host would send and receive IP packets through the "correct" interface (that is, the physical interface that is configured with the IP address used in the packets). Currently the incoming part is already present through the net.inet.ip.check_interface sysctl. If enabled, this would drop packets which arrive on an interface with a different IP address than the one of the interface. But what about the sending side? This appears to be missing. We would need to forward packets not according to the routing table, but according to the source address of the packet (if already defined, otherwise it would be defined through the routing table first). Is anybody aware of this issue? I personally consider this as beneficial for firewall-type setups. Are there plans to implement it?

My provider gives me a tunnel and a /48. Would be possible for my /48 to be divided in two subnet? I have a subnet for windows boxes and a subnet for unix boxes and beetween them an ip330 (nokia, which does support ipv6). For now, only the unix subnet is connected. When i try to add another subnet in my routing table (route add -inet6 -net 2001:7a8:10dd:1:: -host 2001:7a8:10dd::6 -prefixlen 64 ) it appears on the routing table with a /0. I try to ping (ping6 2001:7a8:10dd:1::1) the other firewall (ip330) interface but it does'nt respond. I have configured ipv6 forwarding on the ip330 (net:ip6:forwarding = 1). My freebsd router, which have the gif0 configured is a 4.5-p23. Why does the route appears on netstat -rn with a /0 (2001:7a8:10dd:1::/0 on the good interface, xl0)? I think I'm doing something bad or wrong but I don't know what (newbie in ipv6). If you have any ideas...

But I can not expect all the programs linked to libinet6 (where getaddrinfo is used) to be executed as root ! So I was wondering if there's any option to avoid this, I mean, I'd very much like if my sysctl function didn't require root privileges, then all the applications linked to libinet6.a would get benefit from my modification. Any other suggestion ? If you need more info I'll be glad to explain it deeper. -- JFRH.

I have one problem and i guess that you can help me... I have some FreeBSD diskless machines, 4.7 ones, working fine. The kernel have been compiled with root_nfs, bootp, and bootp_nfsroot support. So, the ip, network, mask and other configurations are been set with bootp/dhcp protocol. But the machines have hard drives, and i do not obtain nothing purchaising then without one... So, i use it. To load the kernel and for swap device. The loader.4th is working fine ...I was looking in the bootp_subr.c code, and saw whatit does... i saw the pxe.c code too, and saw the boot.netif variables. Now, because i know what variables to set, i do not want bootp anymore. :) The boot.netif.ip, boot.netif.netmask, boot.netif.rootpath and so on, i set without problems, but the boot.netif.nfshandle not. :( Browsing one more time the bootp_subr.c and pxe.c codes, i saw the procedures that set this variable. I'm trying to reproduce it in autoconf.c code, but i can't. The other variables i can set in loader.conf, but i need a function that retrieve from nfs server the nfs handle for the root filesystem. Somebody knows the nfs protocol to help me in the job to write a patch to autoconf.c and sets this variable? I guess that is not so hard task, but i do not write one c code a long time ago... :) Thanks very much!!! And sory by the english... I guess that freebsd do not think in this situation. Today, HD is not so expansive, and a misc solution is fine! Maybe, one manner for set ip mask and this magic file handle without dynamic protocols... omestre@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message From owner-freebsd-net Fri Nov 29 11:24:10 2002 Delivered-To: freebsd-net@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 5193837B404 for ; Fri, 29 Nov 2002 11:24:07 -0800 (PST) Received: from mordrede.visionsix.com (mordrede.visionsix.com [65.202.119.3]) by mx1.FreeBSD.org (Postfix) with ESMTP id 8EAC443E4A for ; Fri, 29 Nov 2002 11:24:06 -0800 (PST) (envelope-from lists@visionsix.com) Received: from yogi (unverified [65.202.119.169]) by mordrede.visionsix.com (Vircom SMTPRS 1.4.232) with SMTP id for ; Fri, 29 Nov 2002 13:24:06 -0600 Message-ID: <005d01c297dc$6939f340$a977ca41@yogi> From: "Lewis Watson" To: "freebsd-net" Subject: FreeBSD Gateway Question / Problem Date: Fri, 29 Nov 2002 13:20:43 -0600 MIME-Version: 1.0 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2800.1106 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Hello, I am currently trying to add another /24 network to my existing network with a FreeBSD machine as the gateway to it. Currently, I have a /24 network connected to the Internet w/ a cisco router. I have specified to the cisco router that the new /24 network is connected to 192.168.0.14, which is the external ip address of the bsd gateway machine. The internal ip address for that machine is 192.168.1.1. which is what I have specified to all systems on the new network as the gateway. I thought I had everything exactly the way it should be, except that specifically my Linux machines on the old network cannot find the new network at all. My windows machines on the old network can find the new network. The bsd machines on the old network can find the new network. Other non-Linux machines on the Internet can find the new network. The machines on the new network can find everything but the linux machines on the old network. It appears that only Linux machines cannot figure out where the new network is and I am not so sure that I have set up the bsd gateway properly. Its only one static route that has to be added so I think that routed and certainly gated is overkill. Please tell me what I need other than to specify enable_gateway="YES". I have tried enable_firewall="YES" and set it to "open" but yet I still am having these problems. What do I need to add here to get this going? Thanks.

If you can reach any other machine (bsd to windows, windows to bsd, ...) the linux perhaps have a wrong default gateway.

I went ahead and did a route add for each linux machine (there were three) now they can find the new network as if nothing was wrong. I am still just really confused about it. Maybe they have to have a static route entered even though the router for the old network knows where the new network is.... I have tried every host over the Internet and all seem to find the new network hosts ok.... See below for a simple layout....

Perhaps your code tries the write operation of sysctl, in which case the super user privilege is required by default. If your goal can be achieved without a write operation, the easiest way would be to just avoid the write. If you really need a write operation for every user, you may probably have to reconsider the library design. Since sysctl tends to affect fundamental behavior of kernel, the required privilege is basically reasonable and should not be overridden as an easy compromise.
