Unfortunately, I apparently have no clue how to use gdb with a multi-process server like nsd. :-/ If you are using pf, is it possible you are running into some state limit? On a system that is currently showing the nsd error messages, what does pfctl -si show? I would specifically look at the memory counter. If that counter is something other than 0 you are running into the current state limit (shown with pfctl -sm). Regards, Patrik Lundin
5.4 on a ThinkPad 760EL
I'm trying to install 5.4 on an old ThinkPad 760EL and running into some trouble, probably due to how little RAM it has - 16 MB. The install from the floppy54.fs image went well, no problems. When the machine boots up for the first time, SSH key generation takes an hour (the laptop is very slow) but then the laptop hangs after Starting RPC Daemons:.. I left the laptop on for 12 hours at this stage and it did not change. Is it possible to get 5.4 to run on this machine? I have read INSTALL.i386 and it says that I need at least 32 MB of RAM for 5.4. Should I install an earlier release which requires less RAM? I want to use this laptop for light text editing and checking emails, I realise that it may not be possible to get X to work. Following is a dmesg from a floppy54.fs diskette. Apologies if there is something obvious I should be doing.

You can keep your money. Or donate it to the project. :-) Theo confirmed the laptops I selected on ebay where the right ones.

Even running nsd in debug mode (using '-d') fails to produce any useful information about what reply failed.

How might I find out what's causing these errors, short of recompiling nsd with additional logging output? You may need to raise net.inet.udp.sendspace
Core i5 laptop suggestions
Hello all, I'm currently using a Toshiba Tecra R840, which I like, but ACPI on it doesn't work. It just spins it's fans on resume. Would people please suggest Core i5 laptops that have graphics support good enough to play 3D games such as Oolite, play HD video, and working ACPI for suspend/resume. I don't mind whether it has an optical drive or not. I've always liked Thinkpads are they a good bet? Regards, Laurence
Re: Core i5 laptop suggestions
I'm currently using a Toshiba Tecra R840, which I like, but ACPI on it doesn't work. It just spins it's fans on resume. There remain a few narrow failure conditions. The remaining ones are very hard to diagnose. Sometimes we win with a serial port, or BIOS KT serial, or use the keyboard LED. It is nasty. If you get get another, please keep this one and retry on a regular basis with -current in case we manage to find these problems. Changes which help suspend/resume happen all the time, and magically barriers get out of the way. I've always liked Thinkpads are they a good bet? Well... it is the machines I work on. I don't want to encourage a monocolture, though..
Re: When are default 'set prio' priorities set?
On Fri, Dec 20, 2013 at 4:11 PM, Maxim Khitrov m...@mxcrypt.com wrote: I was under the impression that the packet priority was always set to 3 prior to the pf ruleset evaluation (ignoring VLAN and CARP for a moment), and that 'set prio' on an inbound rule only affected returning traffic that matched the state entry. Here's an artificial example: pass out on $wan pass in on $lan set prio 7 What will be the priority of outbound packets on the $wan interface, 3 or 7? Looking at the code in pf.c, the priority is copied to m-m_pkthdr.pf.prio, but I'm not sure where this value is initialized or reset. I think I figured this out, but I would appreciate a confirmation. The m_pkthdr.pf.prio value is set to IFQ_DEFPRIO (3) in sys/kern/uipc_mbuf.c when a new mbuf is allocated. It is not modified after that except by pf rules. Therefore, packets going out on $wan in my example will have their priority set to 7. Essentially, priorities behave the same as tags. The difference is that priorities are saved in the state entries, so all subsequent packets coming in on $lan and matching an existing state will have a priority of 7 when going out on $wan. Returning packets will keep a default priority of 3 after crossing $wan, but this will be changed to 7 when they match the state outbound on $lan. Correct?
Re: Core i5 laptop suggestions
Thanks for the observations, Theo. ACPI on that particular model doesn't work on Linux either and requires a terrifying array of proprietary drivers on Windows. There are several in a drawer at work, so I'll try current and report back f anything improves in the new year. Merry Christmas and a Happy New year to all.

OpenBSD is getting so bloated these days, it requires so much RAM :) Right :) well, it is for fun of course. I too am playing with NetBSD on a ThinkPad 600E and OpenBSD on an Omnibook 800. You have a fine machine, why let it get dust? those old boxen have sometimes a charme newer don't have, a solid feel and for example older ThinkPads a marvellous keyboard. I use mine to hack a bit and to telnet/ssh around.. I would not recommend using an old release! However both NetBSD and OpenBSD became fat! I don't think it is only the kernel, it looks as if every single program got a bit fatter in the years, even plain old stuff like bash or xterm. To install you have the option to put the hard-disk in a more beefed up system, install on it and then put it back. Running will be less hungry than installing perhaps. Try to find more RAM, you should have slots... 32MB will be already a bit better and with 64 you start to have something useful. Memory upgrade sites tend to agree that 64MB is possible for you. My OmniBook has 32MB with OpenBSD 5.4 generic is usable command-line, however while starting Xorg now works, it is unusable, totally swap-bound. My TP 600E which has more RAM (160 IIRC) and runs NetBSD is instead usable! I can compile, edit, send mail, run GNUstep.. everything excepti running firefox of course. However, I optimized the NetBSD kernel by installing only drivers and hardware I need (I removed all unused busses, cards I won't use, file-systems, etc). I reduced the kernel size by 33%, I did not check the actual memory footprint, but it helped. I bet you can do the same with OpenBSD, but keep your old kernel as a back-up during these experiments! The other thing that really got fatter is gcc, so... if you have another machine with more RAM, do your compiles there :) Riccardo

What has gotten a bit fat is the kernel, but that is due to more device drivers, which people surely don't want us to remove. But back to userland.

[...] I have read INSTALL.i386 and it says that I need at least 32 MB of RAM for 5.4. [...] Apologies if there is something obvious I should be doing. The obvious thing you should do is to add more memory to this system. The 5.4 i386 GENERIC kernel is huge and eats more than half the physical memory, and then the data structures it creates aren't free. There is basically no free memory for userland to run, and your system is swap-bound, hence horribly slow, as you have noticed. Your available options are: - run an old release, which fits in 16MB. I doubt anything = 4.5 will fit in 16MB, so you'd use a 5+ years old, unsupported, release. - build a stripped-down kernel on another 5.4 system and run it on your ThinkPad. This ought to work, but your kernel will not be supported, so if it breaks, you get to keep both pieces. - add more memory to your system. Really. It will help. Can't you see your laptop looking at you with puppy dog eyes? - get a beefier laptop. Anything with more memory will do. Miod I have installed 4.0 and while it does work, even such an old release is barely usable. I'm not too keen on the idea of using such unsupported, possibly unstable software on my laptop, anyway. I suppose the only option is to buy a newer laptop, like you said. There are plenty of good suggestions floating around, most of which can be had for tens of dollars on eBay. OpenBSD is getting so bloated these days, it requires so much RAM :) There's an old tool called `dmassage` (in ports since 3.9) that may offer some help in building a smaller kernel for your situation. http://ports.su/sysutils/dmassage Cheers, Constantine.
dhcpd(8) support for option domain-search
Wanted to verify my understanding that the included dhcpd(8) in base does not currently support the domain-search option: option domain-search domain-list; The domain-search option specifies a 'search list' of Domain Names to be used by the client to locate not-fully-qualified domain names. The difference between this option and historic use of the domain-name option for the same ends is that this option is encoded in RFC1035 compressed labels on the wire. For example: option domain-search example.com, sales.example.com, eng.example.com; dhcpd.conf(5) and dhcp-options(5) don't mention the option. I can currently override the search domains on clients, and it seems like it might be supported in isc-dhcp-server package. Anything likely to make it into base? Simply a matter of patch not having been submitted, or anything deeper than that? -- Darren Spruell phatbuck...@gmail.com
