There are _lots_ of sysctls, even more recently with SCTP support. http://www.freebsd.org/doc/handbook/firewalls-ipfw.html rant This is absolutely the worst section of an otherwise great handbook. Apart from being way out of date it contains gratuitous deprecation, inaccuracies and a large number of plain untruths, was largely written by someone who doesn't use (or like) ipfw, and has examples styled to duplicate an IPFILTER setup. Nothing short of a rewrite from scratch could fix it, despite efforts by several people to clarify aspects; only quite recently the invalid 'ipfw block' command was removed from it. ipfw(8) is a complete (albeit very terse) ipfw reference and I thoroughly recommend studying that instead. Despite what the handbook section says, the sample rules eg the 'simple' ruleset in rc.firewall ARE these days suitable for immediate use using rc.conf variables, DO include NAT functionality (either with natd or ipfw nat) in the _correct_ place in the ruleset, and DO include some stateful rules; that and ipfw(8) are certainly a better place to start than the dreadful examples afflicting the handbook since some years. /rant So ... double-checking I'm doing this right: 1) in /boot/loader.conf: ipfw_load=YES ipdivert_load=YES I thought from your earlier mail that you wanted to use in-kernel NAT? If so, rather than divert sockets (using ipfw's divert action) you want: ipfw_nat_load=YES libalias_load=YES 2) in the kernel config: #options IPFIREWALL #firewall #options IPFIREWALL_VERBOSE #enable logging to syslogd(8) #options IPFIREWALL_VERBOSE_LIMIT=100#limit verbosity #options IPFIREWALL_DEFAULT_TO_ACCEPT#allow everything by default #options IPDIVERT #options IPFIREWALL_NAT #ipfw kernel nat support options LIBALIAS# required for NAT I believe all these can be accomplished with modules on GENERIC kernel, at least on 8.x, with the exception of FIREWALL_FORWARD functionality which does require a custom kernel as it messes with lots of ip paths. If you want to use natd(8) then you'll need ipdivert.ko (as you have above), but if you want to use in-kernel NAT (not yet mentioned in the handbook sections for ipfw or natd, though there since 7.0) then you'll want IPFIREWALL_NAT and LIBALIAS in kernel, or loaded as modules: ipfw.ko ipfw_nat.ko # in-kernel ipfw nat libalias.ko # for in-kernel ipfw nat dummynet.ko # if wanted ipdivert.ko # (or) for natd Basically, natd uses userland libaliasand ipdivert but in-kernel NAT needs in-kernel libalias. The syntax of nat commands is virtually identical for natd.conf and ipfw nat commands, see ipfw(8) natd(8) 3) in /etc/sysctl.conf: net.inet.ip.fw.default_to_accept=1 Interestingly, that one hasn't yet made it into ipfw(8) .. your choice, or you can use firewall_type=open for rc.firewall without that, until you've got your ruleset in action (when default to deny is advisable) net.inet.ip.fw.verbose=1 net.inet.ip.fw.verbose_limit=100 That cover it?

SSL / SSH choosing hardware accelerator first
Hello group, I am currently running FreeBSD 9-Current AMD64. I have a Hifn crypto accelerator installed in the machine. I have noticed that when I connect to the machine using SSH, it does not use the crypto hardware. There was a patch that someone made that forced SSL to use the hardware by default, but I was wondering if there was a way to do this in userland/configuration? It would be nice to have the hardware accelerated cryptography used as first priority before deciding to use the software emulated modes. Does anyone know how this can be done?

sendmail /etc/resolv.conf modified by DHCP
Hello, At home I have my WLAN as 192.168.2.0/24. After moving to my office and rebooting there, I encounter that sendmail receives messages (via fetchmail) terrible slow. I digged into this and see that the sendmail issues wrong DNS requests as (for example): 08:51:18.753491 IP xx.xx.xx.xx.49812 192.168.2.1.53: 12793+ MX? ubuntu.com.Sisis.de. (37) 08:51:18.867365 IP xx.xx.xx.xx.42619 192.168.2.1.53: 12793+ MX? physik.uni-wuerzburg.de.Sisis.de. (50) 08:51:18.982491 IP xx.xx.xx.xx.52554 192.168.2.1.53: 12794+ ? lexasoft.ru. (29) 08:51:19.095490 IP xx.xx.xx.xx.10093 192.168.2.1.53: 12794+ ? des.no. (24) The reason is obvious: - the /etc/resolv.conf on shutdown at home has this DNS resolver; - in my office the system comes up and when at some point the WLAN interface associates, it gets an IP and a new /etc/resolv.conf file; Why sendmail does not honour the new /etc/resolv.conf and stays with the old DNS server IP? How this is supposed to fix? An idea would be to restart sendmail via a devd hook, but maybe there is some config values for sendmail that it always check /etc/resolv.conf for fresh?

Only it's not the speakers that have their operation interrupted, JUST the keyboard (not even the mouse is affected). Guesses: Total power budget (but FIFO?). I don't get that. Do you mean total power allocated to USB? Speaker/keyboard USB ports are on the same internal hub. I'm not sure what you mean here. I've put the speakers on the internal, builtin USB ports (1.x) and they work fine except keyboard starts flaking out. I put them on the USB expansion card (which mouse and keyboard are on because they were starting to flake out on the builtins) with the same exact behavior. High-power OLED keyboard (my eyes!). Keyboard label (if it is to be believed) is +5V 100mA. It's just a standard keyboard with some extra multimedia keys that aren't active (a pity, too). Speakers labelled 500 mA but really only a low-power USB device. Than they shouldn't be messing with the keyboard, right? It usually takes about an hour or so for the keyboard to settle down to a usable state (until then, I'm doing a lot of mousing as the keyboard is near useless). I really don't know where to look for this. I've never even heard of USB powered speakers until I got these (no, I don't pay much attention to what's available unless I have a great need for it). I'm thinking I'm just going to wait until Tuesday and get a brand new pair of wall-powered speakers.

LSI MegaRAID SAS 9211-8i on FreeBSD 8/9?
I'd like to build a new Workstation based on Intels 'Gulftown' for some numerical modelling purposes. Since I realised that on our Dell Poweredge Server with built-in Fusion MPT RAID/JBOD controller even attached SATA 3 GB hard disks seem to be 'faster' than on most Intel ICH9/ICH10 machines we also utilise with FreeBSD 8/amd64, I'd like to have a replacement SAS 2.0 controller like the LSI MegaRAID SAS 9211-8. I do not know much about this controller. I don't want to wait for native SATA 6Gb on Intel chipsets since this is announce for next year and I feel better being 'back to the roots' with SCSI/SAS 2 on FreeBSD. Are there any contraints on this above mentioned LSI SAS 2.0 controller execpt lacking RAID 5/6 level (it should be an replacement for the ICH10 so far for 7 or 8 hard disks/SSDs)? Any comment would be appreciated (please set CC to my email since I do not subscribe the questions-list). Thanks in advance, O.

This would effectively convert your current set to wall-powered, which might be less costly than a new set. Perhaps, but I've been wanting a new set for a while now. The set I had before this one was old when I got them. Last new set I had was from Creative.
