You will probably want to see the PF FAQ [1] on this, specifically the
section on Lists and Macros. It tells you why you should use tables
for this purpose. The list expands to a set of separate single rules,
for !$me and !$mynet respectively.
To quote from the FAQ:
Beware of constructs like the following, dubbed negated lists, which
are a common mistake:
pass in on fxp0 from { 10.0.0.0/8, !10.1.2.3 }
While the intended meaning is usually to match any address within
10.0.0.0/8, except for 10.1.2.3, the rule expands to:
pass in on fxp0 from 10.0.0.0/8
pass in on fxp0 from !10.1.2.3

another way to deal with negative in your pf.conf

Port trunking/bonding
Hi I'm trying to run an experiment (initially) with regards bonding/ trunking ethernet ports under OpenBSD (current) .. but I'm hitting a snag and I haven't been able to google my way out of it as yet ... I have 2 x Broadcom NICS set at 10mbit full duplex (for the purposes of the test .. in real life these will be either 2 or 4 x GigE ports) bonded together using trunk(4) (it's likely to be some time before we can afford 10 Gig infrastructure, but need more than 1Gig between certain segments of our network) My problem is that graphs of the 2 cisco ports show traffic is only going via the 1 port and not being balanced across both ports as I would have expected. What I need is what I believe is referred to as link aggregation .. ie traffic equal to the sum of all members of the trunk(4) and not just the one interface. Helpful pointers gratefully received!

BGP Connection For Two OpenBSD Machines
Anyone, I have one OpenBGP machine running OpenBGPd that is currently connected to the Internet running OpenBGPd. Furthermore, it has two NIC interfaces. The external NIC is designated as xl0(3com) whereas the internal NIC is rl0(rtlink). From the internal NIC, I connected it to another OpenBSD machine running OpenBPGd. I run ospfd and bgpd in these two machines. The results for both bgpctl and ospfctl showed that bgp and ospf is working. But from the OpenBSD machine behind the one that has internet connection, I cannot ping the internet. I added entries in /etc/resolv.conf and an entry /etc/sysctl.conf has been commented out. Yet still not working. Any tips for this? I Regards, Demuel
Re: Port trunking/bonding
Actually .. maybe I'm expecting too much from this ... With 1 of the ports disabled, and roundrobin specified - transfer speeds dropped from 1.2MB/s to about 780KB/s Certainly at GigE speeds the graphs look a little more as I would expect, so it could also be an artefact of testing at 10baseT I guess -- Jon Morby FidoNet Registration Services Ltd tel: 0845 004 3050 / fax: 0845 004 3051 web: http://www.fido.net/

FWIW, there is a newer version of the package -- openldap-server-2.3.11p5.tgz -- and IIRC it works better than openldap-server-2.3.11p4.tgz on OpenBSD 3.9. Also, if you are using bdb as the backend database, you have to install the bdb flavor of openldap-server from ports. If you prefer to use package instead of ports, you have to use ldbm as the backend database.

Re: COMPAT_LINUX in kernel
How do I figure out if my kernel was compiled with COMPAT_LINUX option or not? I didn't compile it. I put COMPAT_LINUX openbsd kernel into google but didn't find anything useful in the first several pages. ``sysctl kern.emul'' will list the available emulations. I have 4.0 on i386 installed from a CD it must be running the default kernel. The GENERIC kernel on i386 is compiled with COMPAT_LINUX. Miod

In the worst case one connection may run slower over two link trunk than over a single link. You need a real multilink capable L2 portocol (like ppp) to fully use the bandwith of the additional link. Ethernet was not designed for that and so bonding/trunking of interfaces give you a sub-optimal performance improvement. -- :wq Claudio Thanks That explains a lot I guess until we can afford / source / upgrade to 10Gig capable infrastructure, we're stuck with bonding and the issues that you describe.

Where should I suppose to declare announce default-route? And I commented all

Does this one announce a default route into bgp to the other machine?
('announce default-route')
OpenBSD machine that established BGP session to the gateway
Does this one accept a default route announced by the other machine?
(comment out 'deny from any prefix 0.0.0.0/0')
$ sudo bgpctl show rib
(if you're in wheel, you can skip the sudo.)
Check the RIB and the kernel routing table. Do the routes look ok? Is the
fib coupled? Is the nexthop valid? Does the RIB on your secondary bgpd
look OK -- valid, correct nexthop?
'bgpctl sh nex' to check nexthops.
compat_linux: Bad system call
Hello OpenBSD 4.0, i386, trying to copy from a 2007 Gentoo Linux. I made sure there is kern.emul.linux=1 in /etc/sysctl.conf and the machine is rebooted. Then I installed the Redhat package. Then I wanted to make the yes program work. I copied all the libraries from the Linux to /emul/linux/...: [EMAIL PROTECTED] ~ $ ldd `which yes` linux-gate.so.1 = (0xe000) libc.so.6 = /lib/libc.so.6 (0xb7e37000) /lib/ld-linux.so.2 (0xb7f65000) There is no file named *linux-gate* so I didn't copy this one. ld-linux.so.2 is copied, it's symlink dereference too, has the same length. The same holds for the libc. Then I made sure ld-2.4.so, ld.so.cache and ld.so.conf are copied and have the same length. Now when I run ./yes in my home directory under the user clock, I get Bad system call (core dumped). I tried under root, the same. #0 0x4ca55282 in ??

PowerEdge 2950 sd0: not queued: error 5
Sorry for the message without body, im a little sleepy and hitted the wrong button... :p Ok, I had this problem last night on one of our shiny Dell PowerEdge 2950s with RAID 10 and SAS disks. For no reason it started screaming sd0: not queued: error 5 on the console, the server didnt crash (no core, no trace) but was in an unresponsive state, i couldnt log on or anything. I was wondering if this error could be a hardware problem (RAID card maybe?). The logs dont show anything notorious, there were no heavy IO at the time of the problem. I'm kind of clueless at what could have been the problem, a quick search showed some old messages with SCSI cards problems only.

Then ldd yes on the Linux system shows these libraries: [EMAIL PROTECTED] ~ $ ldd `which yes` linux-gate.so.1 = (0xe000) libc.so.6 = /lib/libc.so.6 (0xb7e79000) /lib/ld-linux.so.2 (0xb7fa7000) I copied the following files to /emul/linux/... : /lib/ld-linux.so.2 /lib/libc.so.6 /lib/ld-2.4.so /lib/libc-2.4.so /etc/ld.so.cache /etc/ld.so.conf Now when I run ./yes (which I copied too), I get Bad system call (core dumped) and the following trace: 16287 ktrace RET ktrace 0 16287 ktrace CALL execve(0xcf7cc963,0xcf7cc7f0,0xcf7cc7f8) 16287 ktrace NAMI ./yes 16287 ktrace NAMI /emul/svr4/lib/ld-linux.so.2 16287 ktrace NAMI /emul/linux/lib/ld-linux.so.2 16287 ktrace NAMI /emul/linux 16287 yes NAMI /emul/linux/lib/ld-linux.so.2 16287 yes EMUL linux 16287 yes RET oldolduname 0 16287 yes CALL brk(0) 16287 yes RET brk 134529024/0x804c000 16287 yes CALL uname(0xcf7f1488) 16287 yes RET uname 0 16287 yes CALL access(0x50578de5,0x4) 16287 yes NAMI /emul/linux/etc/ld.so.preload 16287 yes NAMI /etc/ld.so.preload 16287 yes RET access -1 errno 2 No such file or directory 16287 yes CALL open(0xcf7f0db0,0,0) 16287 yes NAMI /emul/linux/usr/local/geda/lib/tls/libc.so.6 16287 yes NAMI /usr/local/geda/lib/tls/libc.so.6 16287 yes RET open -1 errno 2 No such file or directory 16287 yes CALL open(0xcf7f0db0,0,0) 16287 yes NAMI /emul/linux/usr/local/geda/lib/libc.so.6 16287 yes NAMI /usr/local/geda/lib/libc.so.6 16287 yes RET open -1 errno 2 No such file or directory 16287 yes CALL open(0xcf7f0db0,0,0) 16287 yes NAMI tls/libc.so.6 16287 yes RET open -1 errno 2 No such file or directory 16287 yes CALL open(0xcf7f0db0,0,0) 16287 yes NAMI libc.so.6 16287 yes RET open -1 errno 2 No such file or directory 16287 yes CALL open(0x505790d1,0,0) 16287 yes NAMI /emul/linux/etc/ld.so.cache 16287 yes NAMI /emul/linux 16287 yes NAMI /emul/linux/etc/ld.so.cache 16287 yes RET open 3 16287 yes CALL fstat64(0x3,0xcf7f0d80) 16287 yes RET fstat64 0 16287 yes CALL mmap2(0,0x150c2,0x1,0x2,0x3,0) 16287 yes RET mmap2 1259569152/0x4b138000 16287 yes CALL close(0x3) 16287 yes RET close 0 16287 yes CALL open(0x4b14a79d,0,0) 16287 yes NAMI /emul/linux/lib/libc.so.6 16287 yes NAMI /emul/linux 16287 yes NAMI /emul/linux/lib/libc.so.6 16287 yes RET open 3 16287 yes CALL read(0x3,0xcf7f0ee4,0x200) 16287 yes GIO fd 3 read 512 bytes \^?ELF\^A\^A\^A\0\0\0\0\0\0\0\0\0\^C\0\^C\0\^A\0\0\0\M^JY\^A\0004\0\0\ [EMAIL PROTECTED] \0\v\0(\0\0=\0\^F\0\0\0004\0\0\0004\0\0\ [EMAIL PROTECTED] [EMAIL PROTECTED]@\M^D\^P\0\^S\0\0\0\^S\0\0\0\^D\0\0\0\^A\0\0\0\^A\0\0\ \0\0\0\0\0\0\0\0\0\0\0\0\0\M-\M-y\^P\0\M-\M-y\^P\0\^E\0\0\0\0\^P\0\0\ \^A\0\0\0\M-\\M^?\^P\0\M-\\^O\^Q\0\M-\\^O\^Q\0\240)\0\0\240U\0\0\^F\0\ \0\0\0\^P\0\0\^B\0\0\0\\\^]\^Q\0\\-\^Q\0\\-\^Q\0\M-p\0\0\0\M-p\0\0\0\ \^F\0\0\0\^D\0\0\0\^D\0\0\0\M^T\^A\0\0\M^T\^A\0\0\M^T\^A\0\0 \0\0\0 \0\ \0\0\^D\0\0\0\^D\0\0\0\a\0\0\0\M-\\M^?\^P\0\M-\\^O\^Q\0\M-\\^O\^Q\0\b\ \0\0\0(\0\0\0\^D\0\0\0\^D\0\0\0P\M-etd\M-T\M^D\^P\0\M-T\M^D\^P\0\M-T\ \M^D\^P\0\M^L\^V\0\0\M^L\^V\0\0\^D\0\0\0\^D\0\0\0Q\M-etd\0\0\0\0\0\0\0\ \0\0\0\0\0\0\0\0\0\0\0\0\0\^F\0\0\0\^D\0\0\0R\M-etd\M-d\M^?\^P\0\M-d\ \^O\^Q\0\M-\\^O\^Q\0\^P \0\0\^P \0\0\^D\0\0\0 [EMAIL PROTECTED] \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0(\0\0\^D\0\0\0\^D\0\0\0\^P\0\0\0\ \^A\0\0\0GNU\0\0\0\0\0\^B\0\0\0\^F\0\0\0\0\0\0\M^?\^C\0\0\M-5\ \b\0\0\^P\^A\0\0\M-A\^F\0\0k\^B\0\0\M-[\0\0\0.\a\0\0\0\0\0\0\0\0\0\0\0\ \0\0\0\0\0\0\0\M-0\^F\0\0\f\^F\0\0\0\0\0\0l\b\0\0\M-:\^F\0\0'\^B\0\0\ \M-\^B\0\0\M^A\b\0\0 16287 yes RET read 512/0x200 16287 yes CALL fstat64(0x3,0xcf7f0e00) 16287 yes RET fstat64 0 16287 yes CALL mmap2(0,0x11657c,0x5,0x802,0x3,0) 16287 yes RET mmap2 1340907520/0x4feca000 16287 yes CALL mmap2(0x4ffda000,0x4000,0x3,0x812,0x3,0x10f) 16287 yes RET mmap2 1342021632/0x4ffda000 16287 yes CALL mmap2(0x4ffde000,0x257c,0x3,0x32,0x,0) 16287 yes RET mmap2 1342038016/0x4ffde000 16287 yes CALL close(0x3) 16287 yes RET close 0 16287 yes CALL mmap2(0,0x1000,0x3,0x22,0x,0) 16287 yes RET mmap2 1382084608/0x5260f000 16287 yes CALL #243 (unimplemented linux_sys_set_thread_area)() 16287 yes PSIG SIGSYS SIG_DFL code 0 16287 yes NAMI yes.core What does this mean?

Re: PowerEdge 2950 sd0: not queued: error 5
I have never seen this but I am very interested in this particular instance. Apparently there is an issue with read ahead on mfi that I have never seen before on OpenBSD but other OS' have run into.

I tried to compile all existing free software SIP packages (about 7) on OpenBSD 4.0 and everything failed. Everyone is claiming portability across Unix, but in reality it's just a wishful thinking, they are portable only to Linux. So I got an idea to try Xten-Xlite and Ekiga under emulation but it failed. With Ekiga tried about 3 different ways. Someone said Asterisk can be used as a SIP client but I didn't find any traces about that in the manpage or in the big Asterisk book PDF. Any idea? I ended up with xten xlite being installed on an old crappy Windows machine next to me, but it's not an example free software solution ;-) CL

Unfortunately, you cannot pull in arbitrary linux libraries and expect them to work because many of them make system calls that are unimplemented in the OpenBSD emulation code. I tried to use the Debian libraries on a dual boot system since it seemed wasteful to install a second set of linux libraries and ran into this same problem. Look at /usr/src/sys/compat/linux/linux_syscalls.c to see what is unimplemented; there are about 30 of them. If you want to stray from redhat_base, you will make it difficult for yourself. -- Mark

What does this mean? That linux_sys_set_thread_area is unimplemented in the
emulation?
IIRC, it's like that:
The linux ld-linux.so dynamic linker calls uname(), gets the version
of the kernel (4.0 on OpenBSD), and based on the fact that 4.0 2.5.58
(or something similar) decides that you're running a 2.6.X NPTL-able
kernel, and goes on to set up things for NTPL threads with
set_thread_area(), etc, even if the program is a non-threaded one.
The solution to that is to run the linux binary with
LD_ASSUME_KERNEL=2.4.2
in the environment.
(in FreeBSD, they have added a sysctl to fake a linux kernel version;
that is completely unnecessary).
However, fixing that won't get you too far -- there are other
problems (first, the simplest one, are the PROT_GROWS{UP,DOWN}
flags to linux' mmap()).
And, finally, the 'shadow root' idiocy is completely unusable, mainly
because of symlinks and binaries that call linux-only shell scripts.

carp and load balancing between different internet connections
Hello list. This is my first post here and also first contact with OpenBSD. I have a question about CARP. I'm engaged a project about redundancy and load balancing between 3 different internet links.They asked me to search for a robust open source solution that can do the job and I came to CARP. However, every example of CARP+pfsync shows a two or more firewalls + one internet connection and nothing like three firewalls + three internet connections that must act like one bigconnection. This illustration describes the situation: http://stpaul.0xbadc0ffe.org/files/carp.png CARP can do that? If not, is there any other robust open source product that can do the job? Thanks and sorry for the engrish.

I think for outgoing traffic PF could balance between the three links (see route-to in the docs), but for incoming traffic load balancing you need: 1) Proper balancing via BGP (see OpenBGPd, but this may be overkill and pricy, depending on your resources). OR 2) Your ISP could provide link aggregation as a particular configuration for your links (which may also cost premium, but probably way less than overall costs associated with BGP). This option probably requires that your internet links are all from the same ISP. ciao Luca

bsd cpu use
Hi All Hate to ask something that might be a simple answer but I am trying to find how it is best / easiest to get the CPU usage of a BSD 4.0 box. I only need the result and not a bunch of other data as I want to store the result in a mysql db. Basically i'm just looking for either the idle number or the % used I have tried with a few different options, but using SNMP (net-snmp 5x) I can't find the actual % used or idle any help or suggestions would be ideal. I'm also working on finding the free memory and some other stuff. I don't want to use MRTG at this point as we are building a custom management system for custom purposes. Thanks James Mackinnon
