VMWare vSphere with OpenBSD and carp
Hi all, Matthew Grooms mgro...@shrew.net 27.07.2009 00:00 Vadim Korschok wrote: Hi Matthew, I've read about your comment on FreeBSD and carp with VMWare vSwitches in Promiscuous Mode. We also get loop packets. I'm very new to OpenBSD and hope you can help us. We performed a bootonly network installation of OpenBSD 4.5. After some searching we can not find the ip_carp.c like you described in your first posting. http://www.mail-archive.com/freebsd-...@freebsd.org/msg30498.html We're also missing the ip_ether.c file. Is it because I'm using a generic kernel ? How can I patch carp to work in VMWare vSphere ? Maybe you can attach me a diff file, because I don't know which should I use (ip_carp.c or/and ip_ether.c) and what's the final patch. We have spent already some days to get it working, I'm already despaired :) Hi Vadim, I'm afraid I don't have an OpenBSD system to generate diffs or attempt a kernel re-compile with. The code that I modified appears to exist in the OpenBSD kernel ... http://www.openbsd.org/cgi-bin/cvsweb/src/sys/netinet/ip_carp.c?rev=1.171 Your best bet would be to contact one of the OpenBSD developers on one of their mailing lists, forward them the patch and ask if someone would be able to port it for you. I am attaching the most recent version since it includes additional locking and a sysctl conditional as suggested by one of network stack maintainers. I haven't tested the ip_ether patch authored by Ermal but it may work and be more acceptable to the code maintainers ( IE, easier to talk them into including the patch in the main source distribution ). Hope this helps and good luck, -Matthew Thanks in Advance Vadim Korschok [demime 1.01d removed an attachment of type application/octet-stream which had a name of esx-carp.diff]

The patch from Matthew is working under FreeBSD, but after the installation
from FreeBSD we found out that load balancing / carpnodes are not supported.
So we can not test same scenario under FreeBSD. I've also tried to patch
OpenBSD without luck.
I've attached a picture: http://www.abload.de/image.php?img=carpicpb.jpg

So what is the problem here ?

Perhaps, but I am not going to enter any 'p*issing contests' of who's got whose name where (besides, I am not implying to be an uber-coder, but I do reserve the right to express my opinion wrt matter at hand). I would like to retain the concentration on the matter discussed. Your opinion is wrong and uninteresting. The only thing you have expressed so far is your detachment from the real world by implying that some sort of retarded document written by committee retards is somehow important. The source code _does_ define the behaviour. Exactly. Perhaps the source code is wrong, but it *EXACTLY DEFINES THE BEHAVIOUR*. All I was saying that it is not always the case. For example: the code in various http client/server applications *implements* the behavior (correctly or incorrectly as it may be), but the behavior is *defined* elsewhere (e.g. a standard); And in the real world all these standards are treated as guidelines. Anyone who has written code from a standard know this. This also means that every person on this planet would interpret language the same. In the open source world people can't even agree what the word free means. similar things could be said about the code in c compiler vs the c standard et al. Show me 2 compilers and I'll show you 2 compilers that don't adhere to the spec. Sometimes this may not be the case, of course, but to categorically imply that 'code defines behavior' is not right in my opinion. It does. Code is absolute, words on paper are not. On the other hand -- perhaps we differ in our understanding of the term defines. You probably implying defines as in results in a given behavior, I am implying defines more in terms of standardization/documentation (i.e. outline/definition of rules/behavior). blah blah blah. Either way -- this only reinforces what I was saying wrt to not expecting any future-compatible behavior of system and thus reducing the scope of disklabel and 'c' partition arguments to the static/current codebase behavior. Compatible with what? The c partition is the whole disk, end of discussion. Don't know what a committee could ever add to that. In fact I do know; they'd attach some arbitrary rules to show how smart they are or to push some corporation's agenda. The last thing they'd do is push anything useful. BTW, don't believe me? Go read ACPI, SCSI IPMI specs. Then go write the code. Let me know how that went.

Re: Intel Mac mini Server Mode
As detailed in the following message, it is possible to use a magic tweak to get the Mac mini into server mode. http://marc.info/?l=openbsd-miscm=120631459418290w=2 This was accomplished with pcitweak which unfortunately no longer exists in X.Org. The only way to get it at this point is to install 4.3 upgrade to 4.4 and then to 4.5. I have also tried using pciutils from ports but this does not work at all on an Intel Mac mini running OpenBSD 4.5. Is there any other solution that works on 4.5? I have searched the archives and every place else I can possible think of as well as the web at large. I haven't been able to find anything thus far. Any help would be greatly appreciated. I know there are others running Intel Mac minis and I hope someone has a solution. Thank you. Yes, I saw pcitweak disappear, too, and I didn't see anything regarding that on the lists. And no, I don't think you need to install the whole OS to run pcitweak. You just need pcitweak and a few libs: $ ldd /usr/X11R6/bin/pcitweak /usr/X11R6/bin/pcitweak: StartEnd Type Open Ref GrpRef Name 1c00 3c005000 exe 10 0 /usr/X11R6/bin/pcitweak 07e05000 27e0d000 rlib 01 0 /usr/lib/libm.so.4.0 0efc 2eff5000 rlib 01 0 /usr/lib/libc.so.49.0 0e80 0e80 rtld 01 0 /usr/libexec/ld.so I personally own a 4.3 (among others) CD set, so for me it's no problem to extract the few files necessary to run pcitweak from the CDs and add it to a new install by hand (wasn't necessary so far, I always upgrade so far). Another option would be to download the old release archives and extract the files from there, or you could get the sources for pcitweak from the 4.3 source tree and compile it yourself. Tas.
sensorsd strange tokens values
I'm using for the first time sensorsd to monitor RAID controller status and motherboard temperature. A script of mine is called that sends me an email. System is OpenBSD 4.4 amd64. The problem is the value of the %2 %3 and %4 tokens passed as arguments to the command. I thought that they should be (in the same order): current temperature, low limit and high limit as set in the sensorsd.conf file. Indeed here are the values I get: %2: 46.00 %3: degC %4: 9223372036581.62 The command I use is command=/path/scriptname %x %n %l %2 %3 %4. Is there some bug or I'm missing something?

Or maybe when you said US-ASCII you were really thinking of ye olde Code Page 437? http://en.wikipedia.org/wiki/Code_page_437 No, I'm thinking about 0x20 (space) to 0x7E with upper and lower case ABCDEFGHIJKLMNOPQRSTUVWXYZ, 0123456789, and the US ASCII punctuation from 0x21 - 0x2F and 0x7B - 0x7E. That is the common character set for keyboard input and printable output across all the systems I use. If all my keyboards, displays, and listing printers used a consistent ISO8859-1 set (for example), there wouldn't be much of a problem. I need to be able to compose edit text-like data for a number of systems which use various character sets. I need to be able to prepare that data in a consistent manner logged into an OpenBSD system from these systems. The printers and other specialized I/O devices producing and consuming my data map 8-bit codes to glyphs in different ways: mostly nonstandard or obscure. Worse, many of them have multiple mappings available. If I set the locale to C, most systems define the characters from 0x7F-0xFF as not printable. Editors, etc, print them as some sort of escaped or hex representation which is consistent and I can enter the values as hex or octal. (n)VI, for instance, shows characters as backslash 2 hex digits, and inputs them as control-X 2 hex digits. The problem is that UTF-8 is a superset of US-ASCII. Various implementations differ incompatibly on how to handle the characters not in US-ASCII, even when supposedly set to the same locale: glyphs are missing from fonts glyphs are inconsistent from system to system characters are printed as (character-0x80) etc. Input encoding from keyboards often also changes. Since the OpenBSD default C locale defines many of the characters 0x7F-0xFF as printable, my local systems attempt to print the characters in ways that are often not visible or readable. I understand that many people don't have US-ASCII keyboards or displays and find the limitation to that character set a problem. Still, the ability to map character/byte/octet values to and from visible marks in a completely consistent manner is valuable to me and perhaps to other people as well. That said, It is my understanding that Unicode support in OpenBSD hasn't been completed yet (correct me if I'm wrong). I don't believe it is there as well, since I haven't seen wchar typed data in sources very often. That's (selfishly) fine for me. Living in a US-English environment shields me from a lot of the need for conversion. Unicode is an extremely unpleasant thing I'm avoiding until the worth of the outcome exceeds the pain of conversion. For instance, will the world settle on a compressed form using the escape convention or will all data change to 16-bit? Or both? Legacy hardware, programs and data have a way of living forever. Translation to and from Unicode will be with us for a very long time even when the common systems and programs are all Unicode-aware. :-( :-( :-( geoff steckel

So, to repeat my question: Are you seeing the same problems as you had with FreeBSD under OpenBSD? I don't know VMWare too well, but I remember that their multicast handling was somehow funny. I would start without using load balancing. Only if everything works as expected without, you can try turning it on. However, there's no guarantee that ``balancing ip'' will work with that virtual vmware switch. But I'm too lazy to explain why :) Carp IP-Balancing has some known limitations (which I really should've added to the manpage): It was meant to balance servers, not pf(4) firewalls. Although it works for pf(4), the performance you gain isn't that high and there are issues if you're using any kind of NAT. HTH, Marco

ifstated with multiple CARP interfaces
Hello,
we have a problem with ifstated detecting state change on multiple CARP
interfaces.
After digging deeper, it seems that reading on the routing socket does
not give us all the state changes that we'd expect. We tried with the
latest snapshot kernel and got the same behavior.
Our CARP interfaces are as follows:
carp0
carp1
carp1010 (VLAN on carp1)
carp1011 (Another VLAN on carp1)
carp2
carp3
The condition we'd like to test is:
carp_up = 'carp0.link.up \
carp1.link.up \
carp1010.link.up \
carp1011.link.up \
carp2.link.up \
carp3.link.up'
Doing a little check using a quick C program (see below), and playing
with the demote counter, we can clearly see why the condition is not
always met as it should:
# ./getifinfo
[1] 20942
# ifconfig -g carp carpdemote 50
carp0 - LINK_STATE_DOWN
carp2 - LINK_STATE_DOWN
carp3 - LINK_STATE_DOWN
carp1010 - LINK_STATE_DOWN
carp1011 - LINK_STATE_DOWN
# ifconfig -g carp -carpdemote 50
carp1 - LINK_STATE_UP
carp1010 - LINK_STATE_UP
carp0 - LINK_STATE_UP
carp2 - LINK_STATE_UP
carp1011 - LINK_STATE_UP
carp3 - LINK_STATE_UP
# ifconfig -g carp carpdemote 50
carp0 - LINK_STATE_DOWN
carp1 - LINK_STATE_DOWN
carp2 - LINK_STATE_DOWN
carp3 - LINK_STATE_DOWN
carp1010 - LINK_STATE_DOWN
# ifconfig -g carp -carpdemote 50
carp0 - LINK_STATE_UP
carp1 - LINK_STATE_UP
carp1010 - LINK_STATE_UP
carp1011 - LINK_STATE_UP
#
Question is, is it normal that the routing socket doesn't report all
changes? Anyone else having similar issues?
Thanks in advance,

Speaking of layouts, it seems that some commands which work inside tmux can't be used in ~/.tmux.conf: I'm trying this in ~/.tmux.conf: select-layout main-vertical I get this: /home/dbolgheroni/.tmux.conf: can't establish current session at line 3 You are trying to set the layout before any sessions have been created, see below. No problem if I comment this line. If I use something like new-window in conf file, tmux doesn't get started, nor an error message shows up. This is probably due to a bug I have fixed earlier today (cmd.c r1.9). Even with this fix, you will not be able to use new-window/select-layout in the configuration file without creating a session first. The usual way to create initial windows in the configuration file is to have something like: # create new session with emacs in window 0 new emacs # create some more windows neww top neww # split the previous window and set its layout splitw splitw selectl even-vertical Then start the tmux server with tmux attach (or tmux start). If you start it with tmux new, tmux will load the configuration file - creating the session and windows with the commands in it - then create the second new session requested by the new command on the command line. I'd like to make this a bit more obvious but so far I haven't thought of a good solution. Will try with the latest snapshot. Also, when in tmux, I can't have the behaviour expected by main-vertical unless I already splitted window. Is this normal? I don't understand what you mean. None of the layouts can do anything unless you have multiple panes already. If you want to force a window to take up only part of the full terminal size, you can use the force-width and force-height options. I was expecting that _if I split_, it will act as main-vertical. Yes, I'm using force-width option. Thank you. -- Daniel Bolgheroni FEI - Faculdade de Engenharia Industrial http://www.dbolgheroni.eng.br/mykey ASCII ribbon campaign ( ) against HTML e-mail X / \

I would like to retain the concentration on the matter discussed. Your opinion is wrong and uninteresting. The only thing you have expressed so far is your detachment from the real world by implying that some sort of retarded document written by committee retards is somehow important. I didn't say this (although I also did not express any support for having this general attitude towards standards as 'retarded documents written by retards'). I think your (and others) emotions are getting in a way of seeing the point I was making. I am not imposing a qualitative resolution that everything which is concerned with source code implementation must be standardized by a committee. You appear to have concluded that I am frowning at the fact that some parts of the source code are somehow not committee-standardized -- this is not so. I am simply noting (i.e. observing w/o blaming-others or anything of such sort) that, in the absence of such (or similar) standards, any consideration for what kernel's mood may bring in a future (e.g. arbitrary changes of interpretation of what entire physical disk equates to; ala forward-compatibility) are not sufficient for the arguments at hand. In fact, I am not even suggesting that someone had made such arguments, I was simply enumerating the reasons I thought were relevant (and rather are easy to agree-on) when considering as to what kernel's mood may be interpreted in the context of the originally raised question (e.g. man pages implications for the disk to be functional without any disklabel being written to it [man 5 disklabel], the reasons given for not using c partition in [man vnconfig, caveats section] et al -- as per original email). The source code _does_ define the behaviour. Exactly. Perhaps the source code is wrong, but it *EXACTLY DEFINES THE BEHAVIOUR*. All I was saying that it is not always the case. For example: the code in various http client/server applications *implements* the behavior (correctly or incorrectly as it may be), but the behavior is *defined* elsewhere (e.g. a standard); And in the real world all these standards are treated as guidelines. Sure. But if such guidelines do exist -- should one not, at the very least, attempt/strive towards meeting them (provided, of course, that the standard/guidelines have been accepted by the implementing community)? We are basically starting to enter the whole discussion of viewing what implementation vs definition mean and this was so not the point of the original question. Besides, I am sure you already realize, that just because one may not be implementing the standard correctly -- it does not mean that one should simply ignore the standard altogether. Anyone who has written code from a standard know this. This also means that every person on this planet would interpret language the same. In the open source world people can't even agree what the word free means. Not every person on this planet may interpret the language the same -- but this does not mean that everyone should abandon well-defined semantics attached to well-known words and start speaking their own non-interoperable junk. This is even more so w.r.t. technical/programming languages. similar things could be said about the code in c compiler vs the c standard et al. Show me 2 compilers and I'll show you 2 compilers that don't adhere to the spec. This is a bit of a moot point -- and I am sure you realize this yourself. Not adhering to the specs does not equate to ignoring them altogether. Sometimes this may not be the case, of course, but to categorically imply that 'code defines behavior' is not right in my opinion. It does. Code is absolute, words on paper are not. How you choose to represent the behavior's definition is irrelevant (code or words, on paper or on screen). I am, at this stage of conversation (if one can call it such), noting the difference (in my opinion) between implementation and definition -- and whilst there are cases when code represents both of such concepts in one place; there are other places when there simply *must* be multiple implementations (i.e. a source code of a given app/library) of a given behavior/interface (standard) so that different processes/boxes/entities/etc can inter-operate with each other. For instance: Hello, how are you? whether being written by me or by you, on screen or on paper is still better than AOAURRAOREAr naoe as10 ao ... right? On the other hand -- perhaps we differ in our understanding of the term defines. You probably implying defines as in results in a given behavior, I am implying defines more in terms of standardization/documentation (i.e. outline/definition of

With the the supplied user-space libpthread, yes. To do otherwise requires building a kernel with the RTHREADS option and using librthread as the threading library. There are still a number of bugs and limitations with rthreads however, so I would avoid using them with any data or programs you can't recreate or check for consistency.

I was, originally, a little hesitant of adding this extra note but
after some thought I might as well mention it... as it may provide
more clarity on the issue of this implementation vs definition
diversion from original question. This is only to show that, in fact,
I think we are saying common things, just in different terms.
I look at the actual ('raw') source code.
I then observe/derive a resulting behavior that such code would produce.
But I then also may want to optimize/improve the code (i.e. change it
with purposes of making the application perform better, faster, etc.)
-- but the question is: by changing the code, some (insignificant)
aspects of the resulting behavior may change as well -- so which parts
of the resulting behavior are relied-upon/are-expected by other
applications and which fall in the 'irrelevant/insignificant or,
indeed, undefined' category? One would need to know the boundaries of
code re-factoring when improving the *implementation* whilst still
retaining the interoperability-enabling interface/contract,
expected/*defined* behavior.
Whether such expectations (behavior definitions) are sometimes written
'inline' in the source code or in some standard publication is not the
main point really.
That's all I am saying. Feel free to ignore or make blah blah blah noises :-)
So now we can, perhaps, get back (if at all) to the man pages and what
they are implying wrt original question.

Re: Colors and layout behaviour in tmux
Unless you are running tmux inside screen, you should not use TERM=screen outside. You should have TERM=screen /inside/ tmux. tmux will set that itself but you should be careful not to change it in shell startup files. Probably I missed this. What's the recommended TERM entry to use with tmux? Now I am running with $ TERM=color_xterm tmux -2 It should match your terminal. For xterm, I use xterm-xfree86 but xterm-color or color_xterm are fine if they work for you. If you are using a 256-color xterm, xterm-256color is probably the best (you won't need -2 in that case). Also, when in tmux, I can't have the behaviour expected by main-vertical unless I already splitted window. Is this normal? I don't understand what you mean. None of the layouts can do anything unless you have multiple panes already. If you want to force a window to take up only part of the full terminal size, you can use the force-width and force-height options. I was expecting that _if I split_, it will act as main-vertical. Yes, I'm using force-width option. Layouts are now applied once when you ask for them, the way to have one automatically applied after you split is to bind it to your split key as well: bind '' splitw\; selectl main-vertical Regards Nicholas
