Re: Backing Up ZFS
I'm just curious at what others are currently doing to back up huge amounts of data. eg. 2TB and onwards. I'm using rdiff-backup and some scripting to backup ZFS snapshots. Other than the use of the ZFS snapshots there's nothing special about it. If your use case is suitable for rdiff-backup, using it with ZFS is a nice combination. For 2 TB+ I do suspect you would want to divide that up into multiple distinct rdiff-backup sets and indeed dependening on situation you may still have a problem with performance. In general I don't know that there is a lot ZFS specific to know about backups other than the availability of snapshots, and other than the potential to use zfs send/receive. Personally I am reluctant to use ZFS send/receive at this stage, because it is too dependent on ZFS. I would love to use it for maintaining a hot standby machine, or having an almost-realtime backup in the best case senario. But I would probably want a generic non-ZFS specific backup as my primary backup as well. One risk that you want to target with ZFS is that of a bug in ZFS itself; such bugs could conceivably be such that it affects your zfs send/receive backup. You mention: 3. ZFS - Remote ZFS using RSync (Living in Australia, there are limits on data transfer of a few hundred GB per month, to costs are prohibitive) rdiff-backup will be good in this senario too, giving you a rolling window of history in addition to an up-to-date mirror. It does do incremental updates including applying the rsync algorithm on individual files. It is definitely slower, in terms of CPU usage, than rsync however so if you have massive amounts of small files you may feel there is an issue. That said, I'm using it regularly to backup millions of files (e.g. collections of Maildir mailboxes). I mention rdiff-backup but of course there are plenty of others. I just happen to prefer rdiff-backup, mostly because of it's rsync mirror + history semantics and completely trivial setup. -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller peter.schul...@infidyne.com' Key retrieval: Send an E-Mail to getpgp...@scode.org E-Mail: peter.schul...@infidyne.com Web: http://www.scode.org pgp3geOfKDD0f.pgp Description: PGP signature

Would this be suitable text to go in the -o options section of mount_msdosfs(8)? large Mount a filesystem larger than 128gb WARNING: This uses at least 32 bytes of kernel memory (which is not reclaimed until the FS is unmounted) for each file on disk to map between the 32-bit inode numbers used by VFS and the 64-bit pseudo-inode numbers used internally by msdosfs.

I have a program that now has all it's libraries resolved but one in preparation to attempt to run the Linux Quickbooks install on FreeBSD. The ldd output, prior to installing /usr/ports/devel/fam (a required shared library) looks like this. ldd ./opt/qbes7/util/qbmonitord ./opt/qbes7/util/qbmonitord: libfam.so.0 = not found libpthread.so.0 = /lib/libpthread.so.0 (0x28072000) libstdc++.so.6 = /usr/lib/libstdc++.so.6 (0x28088000) libm.so.6 = /lib/libm.so.6 (0x28171000) libgcc_s.so.1 = /lib/libgcc_s.so.1 (0x28198000) libc.so.6 = /lib/libc.so.6 (0x281a4000) /lib/ld-linux.so.2 (0x28054000) I install fam to get rid of the not found, perform the following link: ln /usr/local/lib/libfam.so.0 /compat/linux/lib/libfam.so.0 and then I get this: ldd ./opt/qbes7/util/qbmonitord ./opt/qbes7/util/qbmonitord: ./opt/qbes7/util/qbmonitord: error while loading shared libraries: / lib/libfam.so.0: ELF file OS ABI invalid ./opt/qbes7/util/qbmonitord: exit status 127 which kind of makes sense since this library is not a linux library. I'd read that I don't need to brandelf -t linux a library but I tried that anyway, realizing it was likely meaningless (or harmful). It didn't help of course. My next thought was to try and get a libfam.so.0 binary from a linux distro but stopped when it occurred to me that it would be illogical since fam uses kqueue on FreeBSD rather than something called imon. imon is not available for FreeBSD so a linux version shouldn't be able to function if it expects that. On FreeBSD, fam configures itself to not use imon. What is the appropriate course of action to get a linux flavor shared library for fam (or anything which runs into such conflicts) that will work on FreeBSD yet be recognized as suitable for linux under the compat mode?

portmanager looping on libtool on 6.2 - 6.3 upgrade
Hello All, I'm in the process of bringing a production web/mail server up to FreeBSD 7.0 from 6.2. After practicing the process on a non-production box set up in essentially the same manner, I discovered that the only major issue to look out for was the fact that I needed to hold back the upgrade of Python, since the CMS system running on the box will die if it doesn't have Python 2.4 specifically. So last night, I got the actual OS brought from 6.2 - 6.3, and then looked for a different method of port upgrading than I'd used on the development system, since even specifying ports to exclude via portmanager's -ip option didn't seem to work well when going from 6.3 - 7.0. I ran across some articles that told me that I could do ports one at a time, confirming upgrades of dependencies, with a command such as: portmanager editors/emacs -l -ui -f I was able to get some ports, such as bash, upgraded using this method. However, I've now reached a point where virtually everything I try to upgrade is now failing, because it's dependent on libtool, which is stuck in some sort of infinite upgrade loop. Attempting to upgrade it manually via the same command line as above (replacing editors/emacs with devel/libtool15), I end up with output like this: ok to update/rebuild /devel/libtool15 libtool-1.5.26 (yes/no/auto yes to all) [y/n/a] [y]? y [lots of trimmed-out building activity, followed by two more times asking me if it's OK to update/rebuild libtool] MGPMrUpdate 0.4.1_9 command: #1 of 14 cd /usr/ports/devel/libtool15 make -V OPTIONS reverting bsd.port.mk patch -=cd /usr/ports/Mk; patch -R /usr/local/share/portmanager/patch-bsd.port.mk-0.3.6; Hmm...

Does anyone have any advice on how to get this fixed?

Oops, I didn't ever notice that list as I've never needed Linux before. I hate to trouble development lists with an operational issue but this one is starting to look like an incompatibility that is beyond me. The Linux and FreeBSD versions of gamin both fail on inotify_init. Not having the source to the program I'm trying to run makes it very difficult to fix even though the functionality is there (perhaps even superior) on FreeBSD. I ended up using the linux libfam.so.0 from the gamin distribution for Fedora 9. Using it's server fails instantly, using the freebsd port version, the server doesn't fail until the Linux client library attempts to connect. Then it too gets inotify_init not implemented. The Fam list appears to be defunct and I've not yet tried the direct mail contact to the gamin development page. I'm assuming the answer would be that you use native FreeBSD libfam.so on FreeBSD and the linux version on Linux. I've no way to tell the Intuit daemon to do that because of the ABI error and I presume there is an underlying reason why a native library can't be used by a linux binary. I will try the other list if no one has run into a similar problem with other Linux apps. I may be kicking a dead horse but it seems others have talked about using FreeBSD in this manner and it makes it an interesting challenge. The time I'm investing in this is probably not any more time that it would take to configure and secure an openSUSE or Fedora system (having never bothered with them before). Plus it would mean not adding an additional server into my net just for a trivial SMB/file monitoring application. Thanks for the response. I've bumped into a library I can't resolve and I must have a disconnect in how the linux_compat works because I can't see how it could be solved. I have the following: * compat_linux enabled in the kernel, * /usr/ports/emulators/linux_base_fc7 * sysctl kern.fallback_elf_brand=3 * rpm2cpio to alter rpms * cpio to create the directories and place the files where they belong in /compat/linux. I have a program that now has all it's libraries resolved but one in preparation to attempt to run the Linux Quickbooks install on FreeBSD. The ldd output, prior to installing /usr/ports/devel/fam (a required shared library) looks like this. ldd ./opt/qbes7/util/qbmonitord ./opt/qbes7/util/qbmonitord: libfam.so.0 = not found libpthread.so.0 = /lib/libpthread.so.0 (0x28072000) libstdc++.so.6 = /usr/lib/libstdc++.so.6 (0x28088000) libm.so.6 = /lib/libm.so.6 (0x28171000) libgcc_s.so.1 = /lib/libgcc_s.so.1 (0x28198000) libc.so.6 = /lib/libc.so.6 (0x281a4000) /lib/ld-linux.so.2 (0x28054000) I install fam to get rid of the not found, perform the following link: ln /usr/local/lib/libfam.so.0 /compat/linux/lib/libfam.so.0 and then I get this: ldd ./opt/qbes7/util/qbmonitord ./opt/qbes7/util/qbmonitord: ./opt/qbes7/util/qbmonitord: error while loading shared libraries: / lib/libfam.so.0: ELF file OS ABI invalid ./opt/qbes7/util/qbmonitord: exit status 127 which kind of makes sense since this library is not a linux library. I'd read that I don't need to brandelf -t linux a library but I tried that anyway, realizing it was likely meaningless (or harmful). It didn't help of course. My next thought was to try and get a libfam.so.0 binary from a linux distro but stopped when it occurred to me that it would be illogical since fam uses kqueue on FreeBSD rather than something called imon. imon is not available for FreeBSD so a linux version shouldn't be able to function if it expects that. On FreeBSD, fam configures itself to not use imon. What is the appropriate course of action to get a linux flavor shared library for fam (or anything which runs into such conflicts) that will work on FreeBSD yet be recognized as suitable for linux under the compat mode? Try to create and use linux-fam port. I also tried this but it appears that gamin is a more recent implementation. It also provides the libfam.so.0.

I work for a different router manufacturer, so I have little knowledge of Juniper internals, but I have had to worry about interoperability issues, so I've worked with Juniper gear for testing. Also, my general knowledge of similar issues on other routers is very likely to apply to the tradeoffs that Juniper made in choosing and developing its stack software. I very much doubt that marketing issues were a significant issue. Off-the-shelf OS networking has always fallen short of supporting high-end (or even, um, medium-end) hardware routing platforms. There is reason to hope that this is changing, but it has always been the case so far. As someone else already mentioned in this thread, supporting hardware offload for forwarding is a major issue. Core routers (or even provider-edge routers) depend on most of the packet forwarding being done in proprietary hardware. Operating system IP stacks don't support this very well; all of the routers I've worked on used the kernel IP stack only for packets going to and from the kernel itself, and used a different stack for what I call transit packets -- those that are only being forwarded by the local system. Another issue is router virtualization. Although FreeBSD has made some recent progress in supporting multiple IP instances, none of this capability was available when Juniper was deciding to base its operating system on FreeBSD. It is also important to note that having a rewritten IP stack doesn't mean that a system isn't using the original IP stack as well. A number of routers I've seen do this; they have thoroughly custom IP code for doing routing, but the local OS kernel in the router still uses the native stack for its own communications.

Status of hyperthreading in FreeBSD
Netbooks based on Intel's Atom microprocessor are turning into big hits this Christmas season. The Atom, a super-low-power x86 processor, is an in-order machine, which means that except for a few special cases it can spend a lot of time waiting for data to arrive when it encounters a cache miss. So, hyperthreading may make sense on this kind of processor as compared to one with out-of-order execution. Which raises a question: What's the status of FreeBSD's support for hyperthreading?

But on single-user machines, or on servers where the CPU was likely to be shared by two processes that were both privileged anyway, it might make sense to re-enable it. But has this feature of the scheduler been maintained well enough for this to be a good idea?

Re: Network Stack Code Re-write (Possible motivations...?)
A year, or two, ago, I found such information buried within the Juniper website; however, upon recent attempts at further investigation, both for learning about certifications, and subject matter for this topic, I am unable to locate said information. The historic Juniper blurbs were very informative. I am sure that the information is still available, however, I have not been successful in locating it. As for the suggested avenues of investigation, I have not had any coding or employment experience at that level of router development so I don't have the level of specific knowledge-base to make such an inquiry about said reference tables. I also do not have $10-$20K or more to purchase a Juniper router box, so there would not much real motivation to answer my inquiries if I were to be able to get into contact with a sales rep with enough knowledge of the system code to have information to give me. I am very much making an initial inquiry in attempting to get that level of experience, hence my inquiry to the list. I am simply trying to make my own inquiries about the general case, so as to gain knowledge of what routes to take to gain said coding/development experience via experimentation, etc... (Please excuse the pun.) Thanks for the input, though. On Sat, 2008-12-20 at 20:53 +0100, Wojciech Puchar wrote: Thank you very much for the intuitive commentary.

Re: Network Stack Code Re-write (Possible motivations...?)
Thanks again for further information on this topic. Where can I find more information this as a research topic. I am talking about Academic/PHD-level information or industry-level information. (I mean that I am looking at this from a knowledge-base expansion point of view, so don't filter out possible academic avenues because that is where I am mostly coming from in the first place.) Is this the realm where I would have to be one of those six-figure-income embedded programmers to really get my teeth into the subject, or what??? It is OK, you can be honest, hehehe...

I've written portable IP stacks intended for exactly this Of course it can. i just write that FreeBSD network stack WASN'T MADE for that. not if it can or not. I had deliberately worked around this topic because FreeBSD's routing table implementation has made considerable strides in virtualization lately (for which, as far as I know, the credit is almost entirely due to Julian Elischer), and this will probably turn out to make it more useful for commercial routers. So far, however, these changes are irrelevant to the historical question of Juniper's use of FreeBSD code. routing ASIC's and put them there! Mostly, yes. But the system still has to be network manageable. That requires that it send and receive packets. Doing so requires using the same routing information that the forwarding engines are using to forward packets in the same address space. The kernel *does* still need to know routes to any of its destinations. but kernel doesn't forward much packets. It may not not forward any, but your statement that all it does with IP is put data into ASICs is still generally incorrect. It generally does *send* and *receive* packets, and as such it needs routing information. It is possible to use a FreeBSD kernel without the IP stack (and this has been done on particularly deeply embedded processors). However, commercial routers generally do not use their OS kernel this way -- it is far more common that the kernel does send and receive packets within its native IP stack. That forwarding data is usually coordinated with the entity managing the routing data, although sometimes the management is done completely out-of-band, in which case the kernel's forwarding data need not have any connection with the data driven into the forwarding hardware. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/ ___ 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: handbook suggestion
First, let me say that I find FreeBSD to be the best of all the free Unices -- and it is due to the excellent and practical documentation. That said, there is an easy way to make FreeBSD easier for the home user. There are a number of suggestions/methods of doing things in the handbook that are appropriate for the business user that are not needed or useful for the home user. As an example, both the usb drive and scanner sections give instructions for allowing others besides root to mount/use the respective hardware. Both suggestions give advice that restrict the enabling to just one group. For home use it would be easier to just allow any user to mount/use hardware. A sidebar or some such giving alternatives for personal/home users would be nice. Thanks, --dr IMHO FreeBSD documentation lack a section in wich are described case studies and recommendations for particular problems. ___ 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

Responses to icmp packets is one. Almost all hosts will respond to pings unless they're prevented by a firewall. Another way is the type of response to a probe of a port. Sometimes services will respond differently if they're firewalled than if they're not listening on a particular port. Also, very few computers have no ports at all listening. For example, most unix boxes will be running syslogd and listening on port udp/514. That is the default for that daemon. Unless you reconfigured syslogd to listen on localhost only, it will respond to probes. Sometimes a host will respond to a problem with RSETs. It's very, very hard to configure a box in such a way that it's impossible to detect that it's up and running. Run sockstat and look at what's listening on your computer. Then see if you can figure out how to get it to stop listening on those ports.

portaudit and periodic
I am using FreeBSD 7-RELEASE. I installed portaudit. The FreeBSD handbook stated that during the install process, the configuration files for periodic will be updated, permitting portaudit output in the daily security runs. portaudit was not run in my daily security runs. There is no mention of portaudit in /etc/periodic.conf or /etc/defaults/periodic.conf. I read /usr/local/etc/periodic/security/410.portaudit and found that it references 3 variables: daily_status_security_portaudit_enable daily_status_security_portaudit_expiry daily_status_security_portaudit_user I can't find those variables defined anywhere in any periodic.conf file. I understand I can just manually add daily_status_security_portaudit_enable=YES to my periodic.conf and be good to go. But I am wondering about the discrepancy with the Freebsd handbook.
