Hi misc,
I'm trying to setup a new openbsd 3.9 install on i386. It worked before on
that computer when I installed quickly to test for compatibility, but I
needed to finish up some hardware stuff on it and then I wanted to install
for real but it does not work anymore.
It hangs at the disk: line
"Loading /3.9/I386/CDBOOT
probing: pc0 com0 apm mem[639K 382M a20=on]
disk:"
and then it stays there forever.
The computer has two storage controllers. One is an ami-compatible raid
controller. The other is the pciide-compatible sata sil3114 chip. Both
appear to be working.
If I unplug the scsi drives from the controller and leave the controller
in,
it will work.
Also if I unplug the sata drives and leave the controller in, it will
work.
However all appears to be working quite well as I can install win2000 on
it
and all drives work well. Also as I've said openbsd 3.9 worked on it just
a
few days ago, but I can't find what I've changed. I thought it might be a
bios settings problem so I played with the settings, but nothing seemed to
help.
Overall I think this makes no sense, what are some of the problems that
might be happening?
Can you boot from any of the install boot floppies?
If so, can you provide a dmesg?
Sure, I can get a dmesg if I use it with the two sata drives unplugged:

There isn't a shortage of multi-processor sparc64 machines that are available for development use, per se. Theo and I literally had to force Kjell to take a dual U60 machine off my hands earlier this year. The issue is that the longevity of the port is much more dependent on getting proper support for Ultrasparc III and more recent incarnations of the processor and glue logic. It wasn't until Jason Wright and Mark Kettenis started plowing away at the 2006 Hackathon on US3 gear I donated that the port progressed. Theo had a US3 machine for over a year but we could barely get past a hung boot kernel because there were so many nuances in the processor, cache and glue logic. As I type this, I'm testing Mark's latest tweaks to try to get the US3 processor running better than an M5 burning bunker oil as fuel. We didn't ship a Blade 1000 back with Mark because it would seriously upset the center of gravity on his bike for his summer tour! Given the choice between giving EOL'ed hardware a second chance at life and supporting the effort to get the port to work on current Sun hardware, we're currently choosing the latter. i386 and amd64 clearly win from an effort-expended standpoint for SMP enhancements. And just how many significant patches have been committed recently to improve the performance on those platforms? Not enough to start focusing attention on other platforms with multi-processor options. The extension to the "give us open documentation" is "give us money so that we can reallocate human resources in a more efficient, business-like manner in order to try to find other solution paths around problem sets". If your turnaround time for functionality isn't being met by volunteers working in areas they find interesting, there is always the "suitable and adequate funding" approach. There are vehicles available and in place for this type of work other than personal cheques to Theo, Paypal and CD sales. Serious inquiries may contact me off list for more information. No tire-kickers, please. In the meantime, Money, meet Mouth. Sorry to be harsh, but from time to time, the list needs to have this idea pounded solidly back into place in people's minds. --J Jason George, P.Eng. Calgary

No, I didn't mean that. I meant that both gentlemen are personal friends of mine and that the contrast between these two giants of free and open source software could hardly be more striking. Obviously there are elements trying to start an RMS/GNU versus TdR/ BSD holy war. If you are referring to me, you are right off the mark. I never mentioned GNU or BSD and had no intention of starting anything. It was just a throw-away comment in support of the OpenBSD leadership. If you don't find it interesting that two men could take a stand for free and open ideals, and yet interpret those ideals so differently, then fine, it isn't interesting to you. I never said it was not interesting. If you don't like RMS (or TdR for that matter) or his version of free and open ideals, then fine, you have the right to feel that way in most locales. I'm not particularly fond of RMS' views and ideas myself. I very much respect both, but lean towards Theo's ideals and line of practical thinking, which is always very thought provoking for me. But that is just me. I wouldn't waste time trying to start a flame war, because this is just my opinion and I don't want to waste misc@ users time. I do now see that I probably just should have kept my opinion to myself, because it could be misinterpreted and was probably not worth mentioning. But when you reply to the original poster's message feigning that you don't understand his point, well, then you come across as stupid. An inquisitive child could understand the difference between these two mens' views, and understand that some people might find it interesting. Who are you referring to with this? Am I the stupid person for finding a vague comment to be vague? If I don't ask, then I can only make assumptions with something like: '...um... "interesting"' And my comment was mostly meant in jest. Really, truly stupid. And willing to share it with the rest of the world on a public mailing list, no less! Brilliant! I, when confronted with a vague comment, ask a question for clarification. Which admittedly was meant more of a humorous, rhetorical question. Whereas you, confronted with something also vague (to a lesser extent), choose to read a LOT into it and then go on the attack, publicly with a tirade against a bunch of incorrect assumptions. So which is more stupid? If you want to start a holy war about the merits of these two positions then start a thread, preferably somewhere else, and howl into the wind. Nobody cares. We've all made up our minds about which side of the fence we are on. You aren't going to change my mind, or anyone else's. You are only making yourselves out to be a bunch of idiots. I think you have rather made quite the arse of yourself, Breen. I can now see the danger of a holy war erupting from my oversight, but mostly due to presumptuous people like you, who shoot first then ask questions later. This sure doesn't help the image of the OpenBSD user base at all. When we aren't taken seriously it is, in part, because of childish melodrama like this thread. Frankly, I don't much worry about the perception of the OpenBSD user base, because I think any negative perceptions towards it as a whole would be unfounded. There are idiots in every user camp. However this user camp makes up for them and then some, with some really helpful decent people on the list. I just temporarily put them on my twit list. But in the past 7 years or so, I've only put ONE person from misc@ in my twit list and I've since taken them off, now that they've become more reasonable. PS - Jack, some friendly advice, you are only encouraging them each time you reply. They obviously don't care about why you find interest in this subject. They only want to find a way to link you to RMS and then trash you. You find a lot of things "obvious" for a guy who is so presumptuous. For the record, I respect the intentions of RMS and I highly respect the intentions and practical thinking of Theo, the OpenBSD project, the developers and much of the user base. I've been enjoying OpenBSD since 2.5 and I try to buy OpenBSD items and donate whenever I am financially able. I tried to donate brand new SCSI disks when Theo asked for them for the older machines and I purchased a brand new SCSI card for an Aussie developer and had it sent to him, while I was mostly unemployed with small funds. My intentions are honourable here. I messed up by touchin

Hrrmpf. It seems like this goes against OpenBSD philosophy, but there are many who know far more than I on this subject Maybe TDR hasn't decided/thought about it, I don't know.

Say you don't run a dynamic routing protocol you would set the default route to 123.4.5.5. The internal network 123.123.123.0 is yours to play with and carve up as you like, say you take 123.123.123.1 and tell the other hosts in the subnet that's their default gateway. I think what confused my about your suggestion of using bridging is because I'm used to having setups like the one Stuart mentioned: that is, having an ISP assign an IP for the external interface of my firewall (a /30 one in the case of a point-to-point link) and giving me a range of public IPs for which the next hop router will be configured as the IP assigned to the external interface. This info will be configured in the ISP's router (the default gateway from my firewall's point of view) and I'll use the range of public IPs on the internal interface. In these types of cases I wouldn't use bridging; simply IP forwarding. Yes, bridging firewalls are useful where you don't have IP traffic for the whole subnet forwarded to your router by normal IP routing. The situation you describe is one. ISPs giving a `managed router' where they can't be bothered to manage it enough to add routing-table entries for you is another. I've never had to deal with the cases mentioned in the paragraph above, which explains why I've never looked into bridging. Also, I am a bit concerned about having the phones and the office computers on the same subnet: some of these brands of VoIP phones (at least the Cisco 7940s) have a TELNET interface on them and can boot off of a TFTPd server. I think it'd be safer to have the phones on their own subnets, protected by the OpenBSD firewall, so that some curious office worker armed with nmap doesn't start trying to figure out the IPs of all the phone and begins trying to access them just for the fun of it. Also, by separating the phones from the PCs in two different subnets you save a bit on broadcast and possible multicast (if your switch is not IGMP-aware) traffic. Anyway, I guess that's how I'd do it. -Martin -- "Suburbia is where the developer bulldozes out the trees, then names the streets after them." --Bill Vaughan
Firefox/Iceweasel in OpenBSD

blurb blurb
I've been thinking about the legal blurbs in the source files, the most permissive being the one in, for example, src/bin/chio/parse.y I feel it's a bit silly to bother with them, since they have no technical significance. But perhaps it's worthwhile, every once in a while, to ponder the real world and its constraints. The motivation for authors to put blurbs in their work must be some kind of fear. The nature of this fear can be guessed from the wording of the blurb. The authors hope that the blurb affords them protection. I wonder if the following language would provide the same level of protection or better: We, the authors of this work, are giving it away to you, dear reader (and to everyone else), as an opportunity, not as a service. Do with it whatever you want. We welcome your contributions, and we owe you nothing. I imagine that putting this one in place of the orthodox blurb would be an inspiring demonstration of resistance to fear. Surely no judge could misunderstand its intention. Please discuss.

Yes, bridging firewalls are useful where you don't have IP traffic for the whole subnet forwarded to your router by normal IP routing. The situation you describe is one.

To satisfy my own curiosity, what are the advantages in your view that
bridging offers between the internal and external interface compared
to using typical ip fowarding?
(Note: I've never worked with bridging on an OpenBSD firewall, so I'm
a newbie at it.)
I have limited expertise myself --while I do claim some OpenBSD
experience, that experience is has its limits and I can't code. So
here's my understanding, but if I'm wrong anywhere I would be very
happy to get corrected:
Let's assume I have am OpenBSD box with adapters $ext_if and $int_if,
and $ext_if is connected to a switch on a WAN, and $int_if is
connected to a switch that a number of hosts are connected to. Let's
say on the WAN IP subnet 123.0.0.0/8 is being used. Now I somehow want
to provide firewall protection to the hosts on the $inf_if side.
I could use NAT and give both the $int_if and $ext_if NICs IP
addresses. That way I sould make the part on the $int_if side into a
subnet using eg. 192.168.0.0/16. I could assign 123.1.2.3 to $ext_if
and 192.168.1.2 to $int_if. I would not use bridging and none of the
NICs would be in promiscuous mode.
Or maybe I have gotten a small chunk off of that big fat 123.0.0.0/8
network to play with. So let's say I have been allocated
123.123.123.0/24. I would put the external interface in promiscuous
mode (echo up > /etc/hostname.if) but assign an IP to the internal
one, say 123.123.123.123. This IP would be my default gateway on the
internal hosts. They need to know where the heck to send packets that
aren't for hosts on what's now their own local subnet. Apart from the
fact that I'm using IP addresses of the same type (public in this
case) on both sides of the firewall, and that those IPs have to be
properly assigned to/subnetted by me, I'm still king in my castle --
my 123.123.123.0/24 subnet can be fairly independent.
Finally, I could use bridging. This puts both NICs in promiscuous
mode, even if I assign an IP address to one of them, which is a good
idea to allow remote administration (I could assign IPs to both but
there's prolly no good reason to). Also I could decide to only allow
local/serial console administration, and on purpose don't give IPs to
either NICs. With bridging, both sides are logically on the same
network segment, it's as if the network parts in front and behind the
firewall were just one physical network segment. This is transparent
bridging. Neither host on either side needs to even know that that
bridge is even there. And indeed it would be largely useless (well,
useful for range extension beyond max cabling lengths) as long as it
weren't also filtering. Once you packet filter on the bridge it
becomes a magic cable that's just part of a larger segment, but for
some reason doesn't allow garbage through. Good if you have to share a
subnet with undesirables.
I have a setup where there's a switch that's directly connected to the
Internets, that's outside of my control, and that "my" Windows Server
2003 Domain Controller has to share with third parties. Yeuch! So I
put that box behind an OpenBSD nanny^Wbridging firewall. Trouble is,
there are all these other hosts outside that firewall who are directly
connected to the switch, and these all need to talk to the DC and
expect it to be on the same subnet. Also, I want to put more hosts
behind the firewall. No problem with bridging.
I hope this makes sense.
What I don't really understand is where bridging actually takes place,
and what happens in case of a filtering bridge. I thought that
bridging per se happened at the data-link layer of the OSI model,
while packet filtering happened at the network layer.
Neither do I understand what really goes on during IP forwarding as
opposed to bridging, or, for that matter, why I needed to enable
net.inet.ip.forwarding=1 in /etc/sysctl.conf for the bridge to work.
Cheers,
--ropers
PS: What was quite interesting to learn about is how to enable DHCP
requests (inclusive DHCPDISCOVER messages) from certain hosts to
traverse this firewall:
pass on $ext_if proto udp from { 0.0.0.0, } port 68 to
$dhcpsrv port 67
pass on $ext_if proto udp from any port 68 to 255.255.255.255 port 67
pass on $ext_if proto udp from $dhcpsrv port 67 to { 255.255.255.255,
} port 68
PPS: OT, but according to MS' official documentation, you can't turn
on the Windows Firewall on a DC (or if you do turn it on, the DC won't
work. But since putting the OpenBSD box in I've also learned that
there are additional solutions to the unprotected Win 2003 DC problem:
Core Force, building your own Windows "firewall" with IPsec and mmc,
hax0ring the registry of all DCs in the forest to constrain their use
of dynamic ports and then configuring exceptions for everything

This would result in Jumbo's working fine as long as VLANs were not in use. If VLANs were in use and a packet comes in with a size of 2046 bytes or larger, it would be corrupted as it came up through the VLAN layer. Also check the hw max frame size, instead of the MTU, so the alignment fixup is done as appropriate. --snip-- As I use VLANs alot I therefor have a question as this is not 100% clear to me... This was reverted in OBSD 3.8 and 3.9 but not in 4.0. As this according to cvs was reverted after OpenBSD 4.0 was tagged I therefor wonder if the problem exist in the 4.0 release.

And speaking of that, I just re-read your (Patrick's) earlier emails: Patrick wrote: Technically, we don't need NAT, but I want to free up some IP addresses in our company so we can use them elsewhere. That's why I wanted to put all the computers behind NAT. I guess I could assign an entire class C to our office computers, but IMO that isn't really efficient. Sorry if I'm asking stupid questions, but you know all about VLSM/CIDR, right? You know that you don't have to choose between assigning a whole class C subnet or NAT, right? You know that you can apportion any number of bits for your subnet, right? I was just playing with the details you gave earlier (mostly to practice and teach myself): Your friend suggested IPs like 216.139.44.142 and a 255.255.255.192 subnet mask: last octet for IP 216.139.44.142/26: 128 64 |32 16 8 4 2 1 1 0 | 0 0 1 1 1 0 + From 216.139.44.128/26 (x.y.z.1000) through 216.139.44.191/26 (x.y.z.1011), that's 64 IP addresses in total. How many hosts do you have, including the IP phones? How much room for future growth do you need to reserve? If you can steal enough bits off that last octet, then the easiest way may still be a bridge, which has the added advantage of being transparent to the end user. And it can be changed, substituted and removed in the future without so much as an interruption in service (as long as you have a switch with free ports both before and behind the firewall).

Here's the catch - we have VOIP phones that contact an external VOIP server outside of our firewall. I've been doing some research and found out that VOIP phones don't do NAT very well, and because of that you need to put them on their own static IPs. I've tried the sip proxy route, and honestly it was entirely over my head and I just couldn't understand how to get it to work. You are really asking for alot of work to try and do this with two NICs. Here's how we do it as a service provider: 1 vlan for data, 1 vlan for voice stuff. One device/router with essentially three interfaces: one that serves as a wan connection and two ethernet interfaces, one for each vlan. Firewall the data vlan however you want, and give each phone the equivlanet of a static address.

Just because openbsd's threading support isn't as good as it could be, doesn't mean threads are bad. And even if this were the case, it would still not change the fact that plenty of software uses threads, and people would like to run such software on openbsd. Adam

I was asking because although I'm familiar with the usual SIP RFCs (3261 and family) I was not aware of the "SIP actually has ALG built into the standard itself" notion that Girish mentionned and I wanted to know if there was any actual documentation to support this. But the core spec, RFC 3261, http://www.rfc-editor.org/rfc/rfc3261.txt , doesn't touch on the topic at all so far as I've ever noticed. Yeah, I've never heard of this in 3261 either. NAT fixup for SIP is a nasty thing and I've seen a number of broken implementations and incompatible solutions. As a hosted IP PBX provider, we've had the best luck using session border controllers at the edge of our network, which are configured to assume that phones are behind NAT. Yeah, we use SBCs in IMS as well. Unfortunately, SIP is nowhere near being "a" standard where you can assume interop just because you implement a bunch of RFCs. Especially if you mix NAT in. Add to that the 3GPP and OMA additions for IMS and it gets even wilder. -Martin -- "Suburbia is where the developer bulldozes out the trees, then names the streets after them." --Bill Vaughan

There are some old, long expired drafts that touch on the topic, e.g., http://www1.cs.columbia.edu/sip/drafts/draft-ietf-nat-protocol-complications-00.txt There's a best current practice document for call flow that mentions SIP ALGs: ftp://ftp.rfc-editor.org/in-notes/rfc3665.txt but that's more about proxies than about something that untangles NAT.

We tell our customers to not even think about STUN ( ftp://ftp.rfc-editor.org/in-notes/rfc3489.txt ), to not even think about putting the phones behind a firewall with any ALG functionality turned on (one ALG works fine until we issue a reinvite upon changing from ringing all the phones in a hunt group to actually establishing RTP streams with the phone that picks up, at which point the ALG drops all the packets; one mostly works except it plays funny games with port numbers sometimes and starts sending registration requests from a single phone using multiple port numbers, leading to confusion about where we're to send invites, etc., etc.) Unfortunately, SIP is nowhere near being "a" standard where you can assume interop just because you implement a bunch of RFCs.

Is this because giving them NATted, private range IPs previously didn't work so well? The VoIP phones Patrick is using are probably (my guess) using the Session Initiation Protocol (SIP) for signalling. http://en.wikipedia.org/wiki/Session_Initiation_Protocol SIP embeds IP information of the host (phone) inside the exchanged application messages and make use of the Session Description Protocol whenever it tries to set up a voice call (using the INVITE transaction) so that both phone know which kind of of voice/video stream encoding to expect, and on which port and IP it'll be coming to/from. http://en.wikipedia.org/wiki/Session_Description_Protocol If Patrick puts the phones behind a NAT box then the phones will have private IPs and will reflect these privates IPs in whatever SIP messages they send out onto the Internet. Unfortunately, if "public" phones receive these SIP messages with private IPs they might try to contact said IPs, which will fail miserably. It's a similar issue to NAT and FTP, since FTP also embeds IP address inside the control stream of the FTP session. Hence this is why OpenBSD has ftp-proxy(8). If Patrick wants to use SIP behind NAt he'll need the added "intelligence" of an Application Level Gateway. http://en.wikipedia.org/wiki/Application-level_gateway An ALG tracks SIP sessions and performs all the necessary NATs and creates all the dynamic firewall rules to allow incoming and outgoing media traffic for phone calls. I don't think pf alone will fit the bill for this. That's why if he has public IPs available for the phones it might be the quickest route to success. Still, if you *are* stuck behind a NAT and you have SIP phones and you don't want to spend a fortune on an ALG there might be open source solutions (which I have never looked into) that will achieve the same thing.

But since this is 3.7-era code, it's hard to imagine troubleshooting this further. Certainly a 4x upgrade is in order before I go chasing down an mbuf exhaustion problem.

The VoIP phones Patrick is using are probably (my guess) using the Session Initiation Protocol (SIP) for signalling. http://en.wikipedia.org/wiki/Session_Initiation_Protocol SIP embeds IP information of the host (phone) inside the exchanged application messages and make use of the Session Description Protocol whenever it tries to set up a voice call (using the INVITE transaction) so that both phone know which kind of of voice/video stream encoding to expect, and on which port and IP it'll be coming to/from. http://en.wikipedia.org/wiki/Session_Description_Protocol If Patrick puts the phones behind a NAT box then the phones will have private IPs and will reflect these privates IPs in whatever SIP messages they send out onto the Internet. Unfortunately, if "public" phones receive these SIP messages with private IPs they might try to contact said IPs, which will fail miserably. It's a similar issue to NAT and FTP, since FTP also embeds IP address inside the control stream of the FTP session. Hence this is why OpenBSD has ftp-proxy(8). If Patrick wants to use SIP behind NAt he'll need the added "intelligence" of an Application Level Gateway. http://en.wikipedia.org/wiki/Application-level_gateway An ALG tracks SIP sessions and performs all the necessary NATs and creates all the dynamic firewall rules to allow incoming and outgoing media traffic for phone calls. I don't think pf alone will fit the bill for this. That's why if he has public IPs available for the phones it might be the quickest route to success. Still, if you *are* stuck behind a NAT and you have SIP phones and you don't want to spend a fortune on an ALG there might be open source solutions (which I have never looked into) that will achieve the same thing. A quick search on Google did turn this up: http://siproxd.sourceforge.net/index.php?op=overview Could be interesting... -Martin -- "Suburbia is where the developer bulldozes out the trees, then names the streets after them." --Bill Vaughan

My "pamic" [SIC] report is still valid AFAIK, although I'm nowadays always forcing it to 11b mode (not the perfect solution), so I cannot really tell. Another ral-related bug report is #4953, which has been closed but also was very repeatable long after. I have not tried this in at least a month or so, but I reckon it is also still valid and should be re-opened. I'm on a tiny vacation and therefore cannot test it right now. /Alexander

The system I have this problem on is a 3.9, just updated from 3.8, and most config is simply moved, and I might have missed some changes? First off, I thought that doing "pfctl -sA" would actually list ALL the underlying anchors for authpf/*, including the active users, currently logged in, but all i ever get is "authpf".

Try to collect dumps via Kismet and crack wepkey with aircrack. Sadly, there are no tools similar to aireplay for BSD, but it's on my TODO list (I'm slowly rewriting aireplay for BSD.

Note the "might", it depends on a number of factors. and no, it is not feasable to make pfsync realtime. -- Henning Brauer, [EMAIL PROTECTED], [EMAIL PROTECTED] BS Web Services, http://bsws.de Full-Service ISP - Secure Hosting, Mail and DNS Services Dedicated Servers, Rootservers, Application Hosting - Hamburg & Amsterdam

Eventhough pfsync may allow it, it will hurt performance because pfsync updates are done in batches. It is far better to just prefer the active router over the other. (This is actually what OpenOSPFD does (it announces the network only on the active router)). Instead of using direct connections into your two core routers it would be better to use two interconnected switches to connect all four routers on one LAN. -- :wq Claudio
