I think this is a serious issue, the journal should not truncate files, so something should have gone wrong somewhere.. The journalling in SU+J has nothing to do with data integrity. When the system isn't shut-down cleanly, soft-updates are supposed to leave the filesystem in a self-consistent state, except that it may lose track of some freed disk space. The journal allows that space to be recovered without the lengthy background fsck that used to cripple performance. If you are having problems with data integrity you might try gjournal or zfs instead. If you look back at the lists before these were added there was a lot of suspicion about soft-updates and background checks. Some of the problems were explained by some (mostly desktop) drives incorrecty reporting what has been commited to disk - I don't know whether this is still the case. This error about the replay of the journal(s) failing is somewhat disconcerting. I think this is probably a good thing. With background checks you would (if you were looking) occasionally see unexpected soft-update inconsistency during the background check, which would lead to a foreground check on the next boot. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Journalling removes the need for the background fsck which only recovers lost space. With journalling, it should be able to do a journal replay to restore the filesystem to an OK state, My understanding is that the journal does nothing to restore the filesystem other than keep track of orphaned memory. In all other respect it's the job of soft-updates to keep the filesystem in an OK state. When it doesn't you need a foreground check. but sometimes that doesn't restore consistency, in which case it usually fires off a background fsck rather than the foreground fsck. I think if the journal fails, you would really need to run at least a foreground preen, maybe a full fsck. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

It's a matter of can you tie up the resource long enough to wait it out. Right, but if you were to strip-mine the earth's crust and turn all the silicon into GPU cores you still wouldn't even come close to brute-forcing AES256 before the sun turns into a red-giant. If you're saying that WPA is inadequate because weak keys can be bruteforced then the answer is don't use a weak key. If someone breaks such a key then that's pilot error, not an inherent weakness in WPA. Use a key with 100-256 bits of entropy. What I do at home is concatenate 2 ham radio call signs of friends that I can remember. Then I sha256 that and select from the end backwards 15 characters. 60 bits tops - assuming that there was 60 bit of entropy in the hashed data. My key is only twice as long, but about 40,000,000,000,000,000,000,000,000,000 times better at resisting a brute force attack. This won't actually defeat the inherent weakness of using a pre- shared key, but it will take longer for a simple brute force. You should also throw in additional characters from your character set beyond just alpha/numerics. That's good advice for natural language pass phrases where there is only about 1 bit of entropy per character.

I'm looking for a replacement for kget from KDE3 which I use with Konqueror on easynews.com. As the site has download accounting and I have a slow dsl line I have hundreds of files queued-up - often for months. Ideally what I after is something similar - Browser integration - The ability to queue and reorder downloads with only one or a few downloading at once - doesn't lose the queue on crashes. - authentication, and ideally SSL, support I thought I'd be able to get something working with Firefox+flashgot, but aria dumps core, flashgot doesn't seem to do anything with steadflow, urlgfe isn't recognised by flashgot and wxdfast doesn't seen to be able to authenticate to easynews (any doesn't seem to have any queue support anyway). The last time I tried kget from KDE4 they'd removed the queue management and made it like Opera and Firefox's built-in download manager. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

And this software could be manipulated to do things like e.g. send the encryption key to attacker. So from this point of view there is no difference whether the kernel is unencrypted or any other type of software (that runs before the kernel) is unencrypted.

This time I tried both approaches: assigned an IP address explicitly to fxp0, and then no explicit assignment to fxp0. I'd leave fxp0 unset until you've fixed the other problems - it's not necessary for PPP. Modems and routers in PPPoE bridging mode don't normally require any adjustment or other access so there's probably no need to assign address anyway. I still don' get why FreeBSD is having trouble connecting via PPP. The original problem you quoted was with DNS and that's explained by the DHCP on fxp0 overwriting resolv.conf with the router/modem's own non-functional DNS proxy. As regards ppp.conf mine was simply: default: set log Phase tun command adsl: set device PPPoE:vr0 set authname my username set authkey my password add default HISADDR ppp_adsl_unit=0 I tried to specify tun0 interface explicitly, but still no luck. When I start ppp using: service ppp start It shows tun0 is busy. Don't try to specify the tun device number. I've noticed in the past that occasionally tun0 becomes unusable and ppp will switch to tun1. I've seen this happen when I've been restarting ppp a lot. From my understanding it shoud not matter whether fxp0 is assigned the ip address via DHCP server on local lan or via manually - at least this concept works on windows. But in FreeBSD, if I enable dhcp on fxp0, then /etc/resolv.conf is created each time I boot in FreeBSD, so the only nameserver being 192.168.1.1, ie adsl modem ethernet interface. Even if I edit it to include nameservers of my ISP or OpenDNS this file is created each time FreeBSD boots, and these entries are lost, with only entry being 192.168.1.1 There's no good reason to use DHCP in this case, you can simply set a static private IP address (typically a high address in the same /24 as the modem). If you really must use DHCP then it can be reconfigured globally or per interface (type apropos dhclient). I notice that the original resolv.conf you quoted was set by resolvconf. I've never used this so I can't comment on whether it's helping or hindering.

It doesn't have an internet connection if it's not terminating PPP. You have ifconfig_fxp0=DHCP which means you are picking up DHCP from the modem itself not the other side of the PPP link. In bridging mode you only need to configure the underlying ethernet device if you want to route back-out into the router's LAN (PPPoE and IP can share a lan). You don't necessarily need DHCP with PPPoE because PPP can deliver the IP address, DNS etc by itself.

I have a problem with the semantics of the rc scripts for this and
var, though - if you are going to use a memory-backed filesystem, you
should reserve all the space at the outset.
It defaults to 20MB. There's no such thing as an unlimited md-backed
device
Bad things can occur as
you approach the memory limit (like a kernel panic) otherwise.
Provided that you have swap you can have a /tmp that's much bigger
than memory with either md or tmpfs.
I'd prefer something like this:
_mdunit=`mdconfig -a -n -t malloc -o reserve -s ${tmpsize}`
It's a bad idea to use a malloc device as it uses wired kernel memory, the
default allows the files to be written out
to swap rather than panic the kernel.
newfs /dev/md${_mdunit} /dev/null 21
mount -o ${tmpmfs_flags} /dev/md${_mdunit} /tmp
But that's just me. mount_md doesn't quite do this.

As you can see the result was unexpected.
When I try doing it for at least one letter, it works:

cBa

What am I doing wrong?
Or is awk buggy?
Traditional awk implementations don't support {n}, but I think POSIX

Actually the reason I asked is that I wanted to check whether I was ovelooking some key advantage of XTS that justified its being the default.

It seem to me than anyone that worries about attackers tampering with a drive should use authentication in geli, and anyone that doesn't should leave it off and use CBC.

That's because the revisions numbers will have been bumped, it's nothing to do with portupgrade. Ergo, I've since built a new version of perl, a new verion of python, rebuilt every perl module on the system, am presently rebuilding apache22, and I'm sure the system will turn around and require me to rebuild postgres real soon. You would think there's an option to portupgrade that says don't upgrade every single package I've got, Firstly it doesn't. Secondly no one is forcing you to do this, if you want to go through the ports and work out which need an update and which don't then portupgrade will let you do that. but if somewhere in the dependency chain I need a newer version of a thing, then do it.

In practice, I’ve found that this isn’t the case, and my system slows to a crawl and starts paging out to disk when free memory drops to zero, even as half of the available RAM (which is a lot) is marked as inactive. ... That's not a good description of inactive memory, most of which contains useful data. The situation described is undesirable, but not abnormal. It can happen when your physical memory is spread thinly, but most of it isn't being frequently accessed. In that case the inactive queue can be dominated by dirty swap-backed pages. The above and the past FreeBSD thread here, both I referred to, have something in common - the system seems to progressively come under stress due to what one user experienced as missing memory, The FreeBSD link involved ZFS which manages its own disk caching and is relatively new. My guess is that if there is a problem it's ZFS specific. If it were a more general problem I think we'd see a lot more complaints, whereas ZFS already has a reputation for needing lots of memory. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

The difference here is that the DHCP server is in a different address block to the DHCP server, but I'm not sure that's a problem. I think that FreeBSD associates DHCP traffic with the interface its operating on irrespective of normal routing. Have you got a firewall or something else blocking dhcp from communicating? What does ifconfig say?

libc regex word-boundary support fallen-off?
I've noticed for some time that claws-mail and less (which I think use libc's regex(3)) don't support word boundaries in searches. I might be delusional, but I think I've used \b in the past in both of those applications in FreeBSD. According to regex(3) it's an implementation POSIX.2, so the feature needn't be supported, but at the bottom of the page it says word-boundary matching is a bit of a kludge, so presumably it has been. Does anyone know what's going on? I switched from i386 to amd64 last year so it might be something to do with that. I'm currently using 8.2p6. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: Still having trouble with package upgrades
On Wed, 7 Mar 2012 11:28:47 -0500 David Jackson wrote: One faulty argument I heard was that it is often not a good idea to upgrade to new software release. This is an argument that you appear to have completely misunderstood. The point of suggesting that you use release package is that it's a workaround for your problems, and minor releases are not all that far apart. As for compile options, the solution is simple, compile in all feature options and the most commonly used settings into the binary packages, for the standard i386 CPU. Surely that would be the standard amd64. A good software philosophy is to allow software to work out of the box with as little configuration as possible, but allow everything to be configured by the user if they want, by shipping software with reasonable defaults which can be overridden by the user. Make simple things easy and complicated things doable. In GUI, by default, complexity can be hidden from users, but if people want fine grain control, they should be free to use advanced screens of the GUI to get complex, fine grained control. In GUI design, more commonly used settings can be provided more upfront while advanced features for use by experts can be placed deeper in advanced or expert screens oft the GUI. Everything should be able to be configured or accomplished by both GUI and CLI and API. Are aware that FreeBSD is mostly a server OS? doing any system wide all at once OS-release upgrades at all. There is no reason why kernel and userland programs have to be upgraded at the same time... The idea of waiting on a FreeBSD kernel release to upgrade firefox is absurd, and the idea that firefox must be upgraded during a kernel upgrade is also absurd. You don't have to do that, that's complete nonsense. There really should be little reason for release upgrades anymore these days, when the different parts of the system can be upgraded independantly through a binary package management tool, including kernel and user programs. When a new kernel is released, there is no reason to reinstall all of the packages on the system at the same time. You reinstall packages because there are major library changes when you cross a major base-system release. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: FreeBSD 8.2 - active plus inactive memory leak!?

Notably pages may appear in size but not appear in resident for read-only text pages from libraries which have not been used yet or which have been malloc()'d but not yet written-to. Yes. My understanding for the values for the system as a whole (at the top in 'top') is as follows: * Active / inactive memory is the same thing: resident memory from processes in use. Being in the inactive as opposed to active list simply indicates that the pages in question are less recently used and therefore more likely to get swapped out if the machine comes under memory pressure. Well, they aren't exactly the same thing. The kernel implements a VM working set algorithm which periodically looks at all of the pages that are in memory and notes whether a process has accessed that page recently. If it has, the page is active; if the page has not been used for some time, it becomes inactive. I think the previous poster has it about right, it's mostly about lifecycle. The inactive queue contains a mixture of resident and non-resident memory. It's commonly dominated by disk cache pages, and consequently is easily blown away by recursive greps etc. * Cache is freed memory which the kernel has decided to keep in case it correspond to a useful page in future; it can be cheaply evicted into the free list. Sort of, although this description fits the inactive memory category also. The major distinction is that the system is actively trying to flush any dirty pages in the cache category, so that they are available for reuse by something else immediately. Only clean pages are added to cache. A dirty page will go twice around the inactive queue as dirty, get flushed and then do a third pass as a clean page. The point of cache is that it's a small stock of memory that's available for immediate reuse, the pages have nothing else in common.
