Well, you *can* have the dhcp client on FreeBSD send an identifier, and with that identifier the dhcp server can assign the client a static ip lease. If that static ip is registered in your local dns, you're all set. Doesn't work well if you use the client on another network who doesn't offer static ip's.

Now the disks are detected as adaXX devices. The problem still happens though. I think it takes a little longer after I have started dd before it hangs, but it still hangs. One thing seems a little different though. Occasionaly a short burst of interrupts on the mvsX devices do come through. It also seems that a few seconds after I press ^T in the dd window, I see a burst of mvsX interrupts happen and dd will report in/out records and bytes. This did not happen with the ata driver. It is still hanging in "zio->io_cv)" though.

Re: Panic: attempted pmap_enter on 2MB page
Kurt Alstrup wrote: Up front disclaimer: I may very well be wrong on this.. At a high-level, I agree with much of what you say. In particular, if pmap_enter() is applied to a virtual address that is already mapped by a large page, the reported panic could result. However, barring bugs, for example, in memory allocation by the upper levels of the kernel, the panic inducing situation shouldn't occur. At a lower-level, it appears that you are misinterpreting what pmap_unuse_pt() does. It is not pmap_unuse_pt()'s responsibility to clear page table entries, either for user-space page tables or the kernel page table. When a region of the kernel virtual address space is deallocated, we do clear the kernel page table entries. See, for example, pmap_remove_pte() (or pmap_qremove()). The special case for the kernel page table in pmap_unuse_pt() has a different purpose. User-space page table pages are reference counted. When there are no longer any valid mappings contained in a user-space page table page, we remove that page from the page table and free it. However, for the kernel page table, we never free unused page table pages. Instead, they persist, but with all of their mappings marked invalid. In other words, the special case for the kernel page table in pmap_unuse_pt() is skipping the code that unmaps and frees the unused page table page. This special handling of the kernel page table does create another special case when we destroy a large page mapping within the kernel address space. We have to reinsert into the kernel page table the old page table page (for small page mappings) that was sitting idle while the kernel page table held a large page mapping in its place. At the same time, all of the page table entries in this page must be invalidated. This is handled by pmap_remove_pde(). I'm curious to know more about you were doing when you encountered this panic. Were you also using ISO images containing large MFS roots?

Please understand that the removal of isdn4bsd has nothing to do with any belief that it was no longer being used. It was removed because it would not work with a modern kernel as it relied on a locking mechanism that could not be retained if the system was to remain relevant in the modern world. There were many calls, though they may have not reached all those with a vested interest in isdn4bsd, asking if anyone could re-work the code to remove giant locks. Due to the magnitude of the change to the kernel to support a non-giant locked world, there was simply no way to make support for giant a build time option. When no one stepped up to update isdn4bsd, there was really no choice but to remove it. Happily, HPS and taken the job and has an isdn4bsd driver that works on v8 and I hope to see it move back into the base system in the future. http://www.selasky.org/hans_petter/isdn4bsd/ -- R.

I've hacked dhclient exit scripts to synthesize a hostname, if one was not offered by the DHCP server. The host, under these circumstances, gets a hostname derived from the IP address and the supplied domain name, eg: '10-12-34-56.example.com'. This at least gets the box into a place where it has a hostname associated with the address on an external interface. No one else knows that hostname, however.

Regarding your posting to freebsd-stable.

I am using I4B as an answering machine for my phone-line, with the feature to monitor these calls and to download them as MP3 from anywhere in the world (could even be a web-interface, but I hadn't yet the time to write that). I don't want everybody to know my cellular nr; I don't want to (costly) forward calls to my cellular; but I want to be able to monitor and react on calls nevertheless! This is very easy and very comfortable - and currently I have no idea which other equipment could provide me with such functionality (if any would exist at all). And - my router is running anyway, it doesn't consume extra power when doing this - in fact, I think this is one of the most useful things one can do with a computer that is kept running all the time... So, I am sure my demand for this functionality will continue to exist for an indefinite time into the future, and in fact I am sad. To be honest, I am quite clueless now. Theoretically I do understand the problem with I4B. (Practically I do not understand it, because for me it has nothing to do with networking - I do only use the phone call monitoring/handling.) But staying with 7.3 will cut me off from other improvements/fixes, which I would much enjoy. Anyway, there is another open issue for me: my ISDN adapter card is ISA technology, so I will have to get a PCI type card as soon as I replace the mainboard of that system (which is imminent because it's too slow and too power-consuming - the ISDN being the main reason why I didnt do that already). But maybe, now I should look for some completely different approach? Any clues, ideas, pointers, hints, ressources,... are greatly welcomed!! rgds, PMc ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
How dhcp client can set its hostname properly on lease time
Hi, I'm using FreeBSD 8 stable as of 20101006. It is a dhcp client in a private local network, and xorg staff is installed. When I tried to use it from a remote pc with X11-forwarding set, xauth failed to set up .Xauthority as follows. /usr/local/bin/xauth: creating new authority file /home/hogehoge/.Xauthority /usr/local/bin/xauth: (stdin):1: bad display name "unix:10.0" in "remove" command /usr/local/bin/xauth: (stdin):2: bad display name "unix:10.0" in "add" command At this moment, hostname was not set (it's empty) because the FreeBSD box was a dhcp client. Meanwhile, if the hostname coresponding to the ip-address assigned by dhcp server was set manually, the above lines disappeared and X11-forwarding worked well. Now, my question is Are there good way for dhcp client to set its hostname properly on lease time? The following will be a possble workaround, but I'm wondering there can be a smart answer in FreeBSD itself. It is possible to resolve the hostname corresponding to a dhcp-delivered ip-address with a local name server. So, (1) resolve the corresponding hostname from the local name server, (2) set it as hostname, and (3) call them every time when dhcp lease is updated Cheers -- - Mamoru IWAKI Grad. Schl.

Multiple zdevs in the root zpool?
Hi, folks, Currently we have a RAIDZ1 system using 6 x 1TB drives, which we use as a bacula storage device. We now have another 6 x 1TB drives to increase capacity. I'd originally planned to just create another zpool and have two partitions mounted for bacula to store stuff in. However, it would be better in many ways if we could just add the capacity to the existing setup, presumably by creating a second vdev in the original pool. However, according to my understanding, if you want to boot from a zpool, you can only have one vdev in that pool. But what exactly does this mean? Is it really mounting the root fs that's the problem, or is it reading the kernel out of /boot ? Originally I followed the recipe in http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ1 for creating a system using a RAIDZ1 pool, so I have small freebsd-boot and -swap partitions on every drive. I don't really need that much swap space, so is there a way of parlaying that into something like the UFS /boot setup described in http://wiki.freebsd.org/RootOnZFS/UFSBoot ? Except I don't care about BIOS level compatibility with other OSes and so would happily forgo installing a MBR.
