What is max. recommended amount based on?
What is the danger of exceeding it?
How should I increase kern.maxswzone?

# sysctl kern.maxswzone
kern.maxswzone: 0

Do I set it to the total swap size?
Where is kern.maxswzone described?



I went through this on an earlier version but didn't get any warning.
You might find the answer here:

http://blog.frankleonhardt.com/2011/large-swap-files-on-freebsd-die-with-mystery-killed-howto-add-lots-of-swap-space/

The hard limit that's mentioned there is i386 only. I think that may
have changed a bit since 8.2.

This was running 8.2 on AMD64, and it's definitely there (and with the 
same value as the i386 version). The code's there on 9.1, as is the 
manifest constant in param.h and it's still the same value. I haven't 
tried 9.2 yet. So what am I missing about i386?

 even though it seems you can assign existing partitions without any
 problem. The remaining question: Will they be initialized again?

 I know that sysinstall had the option newfs toggle so you could
 skip the newfs step after you had assigned the existing partitions
 to the desired mountpoints.

 It can be seen at

 http://www.freebsd.org/doc/handbook/install-steps.html

 in Fig. 3.19 and 3.24.

 I have to admit that I didn't assume such a significant loss of
 functionality (that sysinstall provided!) in the new installer... :-(

 That's why maybe manually extracting the distribution files from
 the installation media, using the CLI tools, would probably the
 easiest thing: Manually mount existing partitions as desired,
 then extract the installation datasets, and apply any further
 modifications as needed.

OR

Disconnect power line of existing HDD to be reinstalled .
Attach another HDD or drive , for example USB stick .
Perform a fresh install on the new unit .
After verifying that the new install is working properly ,
Shutdown the computer ,
attach power of previous HDD ,
mount it ,
copy all of the new files from freshly installed unit into previous HDD,
Shutdown the computer ,
Disconnect newly installed unit ,
Restart the computer .
It is very likely that your previous HDD will work as like newly installed .

OR

Do the reverse :

From previous HDD , copy all of the required files to the new HDD .
Disconnect previous HDD or unit .
Continue with the new HDD or unit .

If the previous HDD is not bootable , it is necessary to continue with the
new HDD .

I am applying the second kind of steps for all my new installs .

In that way nothing is broken , even there is no back up of the files
because
nothing applied to the existing HDD .

The cost of this operation is to have a spare disk or a USB stick having
sufficient capacity .
Personally I am not using USB sticks for such operations because they may
fail unexpectedly .

Thank you very much .

 Hello there,
 
 I'm writing because after a power failure I was unable to log in on my
 FreeBSD 9.2-RELEASE. The SU+J journal were executed correctly but some
 files disappeared, including /etc/pwd.db. Thus I was unable to log in.
 
 I've been able to regenerate the password database with a live cd but
 I'm afraid that more files had disappeared somewhere else...
 
 I think this is a serious issue, the journal should not truncate files,
 so something should have gone wrong somewhere..
 
 Any ideas? Should I open a PR?

Not sure there is enough to go on for a PR, but something is weird. 

Friday morning our power went down at home for about three hours after I had 
already left for work. When I came home I found the router/gateway box was 
OK. It is still with the old DOS mbr and disklabel scheme, with softupdates, 
and is a pair of disks gmirrored. 

The other box is my first foray into the land of GPT, along with SU+J. It 
was sitting at the 'couldn't mount... Press return for /bin/sh' line. There 
was an error indicating that replaying one or more journals had failed. I 
was able to successfully fsck all the other partitions (besides /), then 
rebooted and system came back up OK.

Both of these machines were recently updated to 9.2 Release from 9.1. It has 
been approximately 9 months, or so, since I last had a power outage like 
this one. Back then they were still 8.3 I think, did not have SU+J and 
recovered just fine on their own.  

This error about the replay of the journal(s) failing is somewhat 
disconcerting. Beyond that, however, I do not have any other details or 
data. Nothing to flesh out a PR, but thought I'd mention what I saw in 
conjunction with your experience.

Re: Authorisation Errors on 9.2

On 14/10/2013 06:37, Beeblebrox wrote:

Hi,
I Inadvertently posted the gnome-keyring bit. That's almost standard error
message on FreeBSD-Gnome. The relevant bit for the error is in fact:
slim: gkr-pam: no password is available for user
However, the user cannot login on a tty without providing a password.

For ssh, the same error and dropped connection occurs for all users. sshd
was modified to allow root login.  All users have valid home directories
defined. From /etc/passwd; I wonder if this has anything to do with it?
sshd:*:22:22:Secure Shell Daemon:/var/empty:/usr/sbin/*nologin*


Could it be a dud /root/.tcshrc? Or /etc/login.conf?

The accounts which try to ssh login also login on host proper and do not
have any login issues when logging-in directly on host - so I think we can
eliminate these problems.


I'm now really guessing - I've not tried 9.2-RELEASE. Given these things 
are usually really obvious when you finally spot them (it happens to me 
a lot, anyway), here are a few obvious things you could think of in case 
it helps. First off, ssh is different from a console login so what's in 
sshd_config matters. That said, the defaults generally work (or used 
to). In no particular order, in sshd_config:


PasswordAuthentication must be yes

KerberosOrLocalPasswd probably yes

AllowUsers, AllowGroups, DenyUsers and DenyGroups need to be set correctly.

ChrootDirectory - this could cause fun if it's set to something.

Other things that might be interesting are UseLogin and UsePAM.

If this was a fundamental problem with changed defaults in 9.2, I'm sure a lot 
more people would have complained.

Regards, Frank.

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

I think this is probably a good thing. With background checks you would

So if I understand everything correctly, the decision logic
is -- when partitions do already exist -- as follows:

a) existing partitions not mounted:
   run newfs
   mount partitions
   copy files

b) existing partitions mounted:
   do not run newfs
   copy files

The installer itself doesn't seem to give a hint about
this logic, even though the manual _might_ suggest it.
I haven't examined the source code to fully verify this
logic, even though it would be a reasonable approach.

The brutal and brute-force approach can work - better if you boot from
a USB stick, of course. You can untar base.tzx and kernel.tzx in your
/, with filesystems mounted.  As Polytropon says, do a backup of what
you'll want afterwards.

This approach will leave a lot of cruft (old versions of shared
libraries, etc.), but will certainly work.  Grab the distribution from

As already stated, those measures are to preserve fs integrity eg meta data
is in sync.  It doesn't ensure that all the outstanding writes are
committed to disk in the event of a power outage.

On GNU/Linux, on Windows you will not require anything else to recover
 your data.


This is complete garbage when using default settings as you imply below.
The default for ext3 on basically every distro still using ext3 is an
ordered journal and don't even get started on ext4.  NTFS by default
can/will also lose data on a power outage.


 I don't want to tweak the filesystem or use something different that the

There is no *warranty* as explicitly stated in
http://www.freebsd.org/copyright/freebsd-license.html

The behavior you wish would slow down disk writes by an order of magnitude
and is already available to users willing to use non-default settings.

 Hi people,

 I'm very interested to tuning /etc/sysctl.conf according to the
 specifications of my PC. I've been reading some guides [1], tutorials
 [2-3], QA [4] and the FreeBSD Handbook's related section 12.12 Tuning with
 sysctl(8), but I think it's much more convenient if I contrast it with
 other examples or experienced users.

 Here is my relevant info outputs for help to improve the sysctl(8)

Hmm, maybe /etc/pwd.db as David mentioned? This is updated on password

As a general rule it is more appropriate to think of tuning in
terms of the workload you intend to apply to your PC. Most changes you can
make will benefit some workflows at the cost of making others less

As already stated, those measures are to preserve fs integrity eg meta data
is in sync.  It doesn't ensure that all the outstanding writes are
committed to disk in the event of a power outage.

Then why random files gets damaged as well even they are not

Random files can be affected because the sectors of the hard disk 
containing the directory entries for those files, not the file data 
itself, may be damaged (ie: the directory was in the process of being 
written OR the pointer to that SECTOR was in the process of being written).


It doesn't mean a file was in active use, just that a chunk of the disk 
with data relevant to that file was. Keep in mind, one sector of disk 
may have data for a dozen files in it (or more). Damage doesn't have to 
occur because a given file was in use at the time of a crash.


If your power grid is prone to failures or blips, I strongly suggest 
investing in a UPS.

I have UPS in my desktop and also I am working on a laptop, so the

be faulty driver, hardware failure, kernel panic, etc.

Re: SU+J Lost files after a power failure

2013-10-14 Thread Bruce Cran

On 10/14/2013 6:16 PM, CeDeROM wrote:

Isn't there Journal to prevent and reverse such damage?


Unlike other journaling filesystems, UFS+J only protects the metadata, 
not the data itself - i.e. I think it ensures you won't have to run a 
manual fsck, but just like plain old UFS files may be truncated as the 
journal is replayed.
For ext3, https://www.kernel.org/doc/Documentation/filesystems/ext3.txt 
explains the different modes, with 'ordered' being default:


Data Mode
-
There are 3 different data modes:

* writeback mode
In data=writeback mode, ext3 does not journal data at all.  This mode provides
a similar level of journaling as that of XFS, JFS, and ReiserFS in its default
mode - metadata journaling.  A crash+recovery can cause incorrect data to
appear in files which were written shortly before the crash.  This mode will
typically provide the best ext3 performance.

* ordered mode
In data=ordered mode, ext3 only officially journals metadata, but it logically
groups metadata and data blocks into a single unit called a transaction.  When
it's time to write the new metadata out to disk, the associated data blocks
are written first.  In general, this mode performs slightly slower than
writeback but significantly faster than journal mode.

* journal mode
data=journal mode provides full data and metadata journaling.  All new data is
written to the journal first, and then to its final location.
In the event of a crash, the journal can be replayed, bringing both data and
metadata into a consistent state.  This mode is the slowest except when data
needs to be read from and written to disk at the same time where it
outperforms all other modes.

SU+J isn't a journalled filesytem, it's a filesystem with soft-updates
that journals information about free space so it can be recovered
without having to go through the whole filesystem.

Re: Advice sought on Portmaster -Faf and deleted ports

2013-10-14 Thread Scott Ballantyne
 
  Hi,
 
  I'm following the recipe at the end of man portmaster for deleting and
  reinstalling all my ports, which I have done many times in the
  past. This time, I am getting errors on the portmaster -Faf step
  involving deleted ports, and I'm not sure how to deal with this
  easily.
 
 What errors, exactly?

Well, for example:

portmaster -Faf
it starts to fetch a bunch of files
it finds a port which has been deleted, such as
linux-base-fc4
and it says, linux-base-fc4 has been deleted.
terminating
terminating
terminating
etc.

 
  So, I am seeking expert advice here. Is there a way to automate this
  and keep myself out of trouble, or do I need to do a 'port-by-port'
  upgrade of each port?
 
 It should just work.  Have you converted to pkgng?
 

I dream of the day that the ports system will just work. I don't use
binary packages, are you saying that pkgng will deal with this issue
automatically?

Thanks,
Scott

As I understand it UFS+J gives the same reliability as UFS with a normal 
fsck after a crash, so on a development system the only ways to improve 
the situation would be to mount with the 'sync' option, disable write 
caching on the disk or to switch to a different filesystem like ZFS.

Please explain the logic in which this helps anything.

Already standard behavior as implicitly seen in this thread.

No and any fs that requires such a system is broken by design.

mount -o sync or use ZFS. Both require hardware that correctly report
success to fsync.

You shouldn't ever need to recheck the filesystem if it was shutdown cleanly.

However, it doesn't hurt to fire off an fsck once a year or so just to look for
any unexpected issues.

 Or to do a filesystem check after crash..?

Yes.  Without journalling, you'd normally perform the full timeconsuming fsck
in the foreground.  With journalling, it should be able to do a journal replay 
to restore the filesystem to an OK state, but sometimes that doesn't restore
consistency, in which case it usually fires off a background fsck rather than
the foreground fsck.

 Are there any flags like that to mark filesystem
 unclean and to force fsck after n-th mount? That would assume
 disabling journal and soft updates journaling I guess..?

/etc/rc.conf should support something like the following to do what you ask:

fsck_y_enable=YES
background_fsck=NO
force_fsck=YES

 What would be the best option for best data integrity in case of
 crash? That would be helpful for development systems I guess :-)

Well, you can use mount -o sync and disable write caching via hw.ata.wc=0 or
similar depending on what kind of drives you use.

This will cause a massive loss of write performance, but will greatly improve
reliability-- i.e. fsync() and such are not as likely to lie about whether bits
have made it to disk, even in the face of hardware which lies about 
ATA_FLUSHCACHE
(or SCSI SYNCHRONIZE CACHE, etc).

Unlike other journaling filesystems, UFS+J only protects the metadata, not 
the data itself - i.e. I think it ensures you won't have to run a manual 
fsck, but just like plain old UFS files may be truncated as the journal is 
replayed.


This discussion skirts the critical issue - are files that are not open 
for writing endangered? No description of the uses of journaling can be 
considered informative if it doesn't address that explicitly. As a naive 
user I have always assumed that once closed, a file was invulnerable to 
improper shutdowns, but this discussion shakes that belief.


I expect the answer may be different for SSD and spinning disks.

One of the most annoying things about SU+J is that fsck asks if you

I'm following the recipe at the end of man portmaster for deleting and

What errors, exactly?


Well, for example:

it starts to fetch a bunch of files
it finds a port which has been deleted, such as
linux-base-fc4
and it says, linux-base-fc4 has been deleted.
terminating

That's correct.  linux_base-fc4 is long gone (years), replaced by 
linux_base-f10.  portmaster sees no way to upgrade that port, so 
evidently it quits.


If you have ports that far out of date, the upgrade process is going to 
be long.  Ports where the system does not know the replacement will have 
to be handled manually.



So, I am seeking expert advice here. Is there a way to automate this
and keep myself out of trouble, or do I need to do a 'port-by-port'
upgrade of each port?


It should just work.  Have you converted to pkgng?



I dream of the day that the ports system will just work. I don't use
binary packages, are you saying that pkgng will deal with this issue
automatically?


No, the concern was that you might have already converted to pkgng but 
still used the old package tools.

Okay, but why the fsck didn't run by itself to detect that the journal

 shutdowns, but this discussion shakes that belief.

Well, it's good to be a little paranoid if the data matters.  :-)

First, unless you call fsync() before close() and your OS and/or drive hardware 
isn't being deceptive when fsync() returns about whether the bits have made it 
to permanent storage, then you might be surprised at just how long the 
unwritten buffers containing the last updates to the file data take to get 
properly flushed to disk.

 I expect the answer may be different for SSD and spinning disks.

Second, this is an excellent point: however, it also applies to anything where 
the actual hardware block size does not match the device blocksize that the 
filesystem thinks it has-- so new 4K sector rotational disks also have some 
risk.

The basic issue with SSDs is that you (or the drive firmware, more precisely) 
need to read in an entire hardware sector, update the portion with changes in 
cache memory, do a bulk-erase of that block, and then scribble that back out.  
Good drive firmware actually writes out to a different block than the original 
for wear-leveling purposes and only updates the flash translation layer once 
the new version of that block is written.  That makes the drive mostly immune 
to major data integrity issues even if powered off in the middle of the process.

Less-than-good firmware, aka buggy firmware, can lead from power-failure to 
data loss of files which were not being modified at the time.  And may you 
possess recent working backups if the FTL somehow ever gets confused!

  encryption.
[..]
   I must reiterate, FreeBSD does not support Suspend to Disk (state S4 aka
   'hibernate') on ANY platform, except - perhaps - on machines supporting
   S4 in BIOS (hw.acpi.s4bios=1) which are very rarely spotted in the wild.
  
 And even suspend to RAM doesn't work on every machine [2].

 [2]: https://wiki.freebsd.org/IdeasPage#Suspend_to_disk
  
   That page IS about Suspend to Disk - but only as a wishlist idea, as it
   has been for many years.  Someone did take it on as a Google SoC project
   years ago, but nothing ever came of it to my knowledge.
[..]

  Thanks Ian for clarifying that FreeBSD does not support Suspend to Disk. I
  just assumed all major distros supported all the suspend states. Now I am
  looking for a UPS that cleanly shuts down the machine when there is a power
  outage.

Hi Yudi,

you haven't said what sort of machine (desktop/server/laptop) or how 
long a mains power fail runtime you're after, so it's impossible to 
guess what sort of size UPS you might need ..

  I am looking at a APC Power-Saving Back-UPS ES 8 Outlet 700VA 230V AS
  3112http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BE700G-AZtotal_watts=200tab=features,

I don't know about that model; it makes no mention of shutdown alert / 
control at all, only 'some models' have a USB connector, and I couldn't 
find the manual for it there.  Certainly not all 'desktop' UPSes support 
what's needed to communicate and shutdown cleanly, so check carefully 
both the specs and that software (apcupsd or nut) supports the model.

I gather from your timestamp (and that model) that you may be in 
Australia, in which case you could browse from here for the APCs:

http://www.apc.com/products/category.cfm?id=13ISOCountryCode=au

[However that page currently throws errors on the various model links of 
'Element CACHE.APCTOSECOUNTRYMAPPINGS is undefined in APPLICATION.' :( ]

  anyone know if apcupsd daemon works fine under FreeBSD or should I be
  looking at Network UPS Tools (NUT).

I'm sure there are people here who can advise.  I've only setup Eaton 
and PowerWare UPSes, and those on a Debian linux server, using NUT.

cheers, Ian

I have the opportunity to replace an aging UPS with a new APC BE750G
Power Saving Battery Back-UPS one. My question is if anyone here has

the unit is basically useless.

I Googled and found an old message regarding FreeBSD and a similar UPS
http://lists.freebsd.org/pipermail/freebsd-questions/2004-October/062543.html
dated 10/2004. Are those issues still relevant? According to
http://www.apcupsd.com/manual/#freebsd I need to insure that this is
a SmartUPS The unit I am looking at does not qualify.

I might add that my present unit is connected to a Windows machine. I
intend to replace that one and hook up both PCs to it.


sysutils/apcupsd works with a lot of APC units.  Offhand, I know it 
works with a several-year-old Back-UPS XS unit (not mine), and with all 
my older Smart-UPS units.  Mac people say that apcupsd works with the 
BE750G: http://hints.macworld.com/article.php?story=20100314155518972


The Smart-UPS models are preferred for better quality.  In some of the 
newer units, APC has gone to a proprietary communications protocol. 
The problem units are shown on the apcupsd.com site.

As to the second problem - csh: No such file or directory. At the risk 
of pointing out the trivial, is root's home directory valid? Why not 
post /etc/passwd and we'll check :-)


Could it be a dud /root/.tcshrc? Or /etc/login.conf?

I assume you've configured sshd to allow direct root logins. If you

Running fsck in single-user mode may not be sufficient.

You may need to run fsck_ffs from a USB-stick installation or live CD.

I remember reviving a FreeBSD partition that way, normal root partition not

I once revived a FreeBSD partition with fsck_ffs from a USB-stick installation

It helps to have a UPS to protect against short power failures and allow

Perhaps you should post the links that don't work with the latest Linux

caused by Flash Player and not by something else.

To add more confusion to this fray, although it may not help with gray

new pepper style Adobe is going with now.


FWIW, I did put in a port to fix drm issues on any site which was 
stopping videos playing (again, not your specific issue, but what 
appears to be in discussion here) and which allows flash to work using 
any browser - uses linux dbus libraries (weird). Not sure of the status

 Hi all. Is it possible to install FreeBSD without formatting the disk?

Yes. The installer supports not formatting existing partitions.

 I have one directory of data that I want to keep.

You should still make a backup, because I want to keep does

 I can boot from the

 could I install the OS from there?

You simply re-enter the installer, assign the (existing, but now
empty) partitions to the desired mountpoint, make sure _not_ to
newfs them, and then commit to the installation as usual.

An alternative would be, after preparing the partitions, mount
them as desired and extract the installation datasets from the
installation media manually (via shell commands). Still you might
miss other steps the installer performs.



 I've done ZFS on root installs with
 the shell and mounting the zpool to /mnt, would that work here too?

Probably yes (never tried that myself).

Oh, seems you're right. I've checked The FreeBSD Handbook for
the relevant instructions for using bsdinstall at

http://www.freebsd.org/doc/handbook/bsdinstall-partitioning.html

and

http://www.freebsd.org/doc/handbook/bsdinstall-final-warning.html

and I didn't find an option to _not_ initialize existing partitions,
even though it seems you can assign existing partitions without any
problem. The remaining question: Will they be initialized again?

I know that sysinstall had the option newfs toggle so you could
skip the newfs step after you had assigned the existing partitions
to the desired mountpoints.

It can be seen at

http://www.freebsd.org/doc/handbook/install-steps.html

in Fig. 3.19 and 3.24.

I have to admit that I didn't assume such a significant loss of
functionality (that sysinstall provided!) in the new installer... :-(

That's why maybe manually extracting the distribution files from
the installation media, using the CLI tools, would probably the
easiest thing: Manually mount existing partitions as desired,
then extract the installation datasets, and apply any further
modifications as needed.

  install 80! ports to get it. Is there an easier way?
 
 Actually I think you want x11-toolkits/gtk20..? Would pkg_add work for
 you?
 
 Maybe graphics/librsvg2 is better suited (even though it's version 2 of
 the library). The problem initially mentions will remain: lots of
 installation dependencies. Sadly, that seems to be normal today as
 modern software tends to rely on layers of libraries of abstraction of
 tools of utilities of stuff of layers of layers of other abstractions.
 :-)
 
 As you see: gnome-desktop and gtk20. That should bring your warning
 lights up: lots of dependencies ahead!
 
 When you try to install a simple desktop environment, you'll be
 confronted with hundreds of packages to be installed, some of them
 you've probably never had thought of in regards of what you need to
 install a desktop, such as two or more different databases, LaTeX,
 translators, and other surprising stuff. This will probably apply to
 most complex components and parts of desktop environments or X11
 toolkits (as mentioned above).
 
 As I mentioned, the librsvg2 port will install lib/librsvg-2.so.
 It might require you to re-install your target application to link
 against that library.
 
 A library libsvg.so (without version number) doesn't seem to be in the
 ports tree by that name.
 
 My lazy man's method of searching what port might contain the library:
 Midnight Commander, go to /usr/ports, Meta-?, seach in pkg-plist,
 search for text librsvg and examine the results with PF3. This method
 relies on approaches that might be wrong... :-)
 
 Note that my (locally installed) ports tree is not up to date anymore so
 you should consider performing a search on a recent tree to make sure I
 didn't miss anything.

Thanks Polytropon, but the one I needed was this:

x11-toolkits/py-gnome-desktop/pkg-plist:%%PYTHON_SITELIBDIR%%/gtk-2.0/
rsvg.so

I have given in, let it install all 80 ports, saved the one shlib I need 
and deleted the ports again. All is now well.

By the way, I needed it for the 'screenlets' Python applications; in 
particular ClockScreenlet.py.

I don't know what others think, but what *I* really want is that the
free software versions of Flash (gnash and klash, etc) work at least as
well as versions of Adobe Flash do, or if versions of Adobe Flash are
to be used, that it will be free and covered by the GPL.

Its unlikely to happen unless we start a campaign among the Free
Software users of the world to make Flash free software.

Yes, I know HTML 5 is just around the corner, but we've seen a
concerted effort already (in the European Parliament at least) to
introduce DRM into HTML 5 and though it may make using Flash marginally
easier, it would be a retrograde step if DRM is to be introduced.

So what are we left with?  Free software to replicate what Flash
does (at least) that does not have the taint of proprietary software?
Is that not an achievable goal?

I can't code but would be willing to join a project with those
achievable goals, but it hasn't appeared yet, so I don't seriously
expect it will happen any time soon.

Try 9.2 for AMD64. The i386 version should also work (as
you are low on RAM if that might matter, depending on

Depends. VMX EXE files may work via the SimH emulator. For
DOS EXE and Windows EXE files, there are dosbox and wine.
Those compatibility packs can be easily installed. They
are not part of the OS.

Definitely no bluescreens in FreeBSD. The system will behave
exactly as intended and won't change its mind a few days
after installation. :-)

 dual core processor 4000+ 2.11 GHz 960 MB RAM?

That's a 64 bit CPU, if I remember correctly. The AMD64 version
should run fine. But as you are a little bit low on RAM, you
might consider using the i386 version (32 bit version) if you
don't _need_ to run any 64 bit application. Especially as you've
mentioned to run EXE files, this might be the better solution.
From what I've heared, wine (the Windows compatibility pack)
runs better on i386 than on amd64. (I'm running it myself on
the i386 OS on a 64 bit system without any problems.)



 im always in internet watching live camers,what do you suggest
 me to use os type?

Is this via web? In this case, only the web browser matters.
The typical candidates Firefox and Chrome should be fine.
The OS does not matter here.

If you need a proprietary program to watch the live cameras,
often available only for an outdated Windows version, running
it with (the mentioned) wine should work. (I've successfully
tried something like that with a program to watch CCTV cameras
via Internet.)



 i like to save pictures and videos and never lost them,if you
 think your os is gonna spoil and lost my all files then i dont
 need it.

Definitely no problem. But keep in mind: _You_ are responsible
for creating backups! FreeBSD offers excellent tools to do so,
no matter if you want to backup to disks, DVDs, the Cloud, or
even to old-fashioned tape.

Saving pictures from videos is no problem. There is mplayer and
mencoder. It plays, records and converts _everything_.



 i want stable os and never to reinstall or update

That approach is unreasonable, I think. You _should_ update when
security updates become available. It's in _your_ interest to do
so, because effciency, security and usability improves from version
to version. Luckily, FreeBSD has an easy way of updating the OS.
It's _independent_ (!) from your installed applications and of
course from your data. You can also decide to update your programs
independently.

However, a install once, then keep using scenario is easily
possible with FreeBSD. (My home system has been installed in
summer 2011 and worked _flawlessly_ since that point, never
touch a running system.)



I suggest you make yourself familiar with FreeBSD by using the
resources from http://www.freebsd.org/ and you _might_ also want
to check out PC-BSD (might be perfect for what you want) and
VirtualBSD (easy way to try it out without installing it).

Regarding to driver issues you better stay with Microsoft or switch to

Free/libre and open source software does less good support proprietary
codecs and software. At the moment there is a thread about Adobe Flash
on this list. The best choice could be Windows, perhaps installed as
guest to a virtual machine, so that you always can restore it by using
snapshots.

For multimedia Linux might be better than FreeBSD. Neither Linux, nor
FreeBSD tend to lose data, you even shouldn't lose data when using one
of Microsoft's less good Windows versions. It's more likely that users
have less good backup and archiving strategies.

If you want to consume multimedia by the Internet, you likely need to
install security updates and software to use stuff based on proprietary
software. You could set up a text editor and never need to update or to
reinstall something, but the Internet and consuming multimedia likely
need updates from time to time.

Start an adventure ;), nobody will give you a guarantee,
self-responsibility is a catchword for free/libre and open source
software.

FreeBSD and Linux are similar operating systems, on both kernels more or
less the same multimedia applications do run, but the more recent
versions are provided by Linux and multimedia is better supported for
Linux.

I'm an Arch Linux user, it's similar to FreeBSD regarding to a port like
system, however, for your needs IMO Debian Linux stable release might be
the less risky choice. OTOH, why not simply testing FreeBSD?

 I don't know what others think, but what *I* really want is that the
 free software versions of Flash (gnash and klash, etc) work at least as
 well as versions of Adobe Flash do, or if versions of Adobe Flash are
 to be used, that it will be free and covered by the GPL.

First of all, keep in mind you're walking corporate territory
here. No company will give you anything for free, and even if
it looks free, there's a catch somewhere. Flash as a technology
is dying. It didn't make the transition to the growing mobile
markets. That's why Adobe does not continue its Linux line of
product - a completely reasoname business decision.

People who use, or to be correct, _abuse_ Flash as a replace-
ment for markup and content are not interested in bringing their
product to your attention and reception.

What I'd like to see would be a Flash plugin integrated in
the web browser, with the option of being switched off. I'd
consider it a 1st class citizen by demanding that is has the
same status as embedded media, centered text, a PNG image or
a hyperlink, being a functional module of the web browser
like the renderer, the CSS interpreter, the JS interpreter
or something like that. Could you imagine to install a pro-
prietary plugin to be able to see a JPG image? To see text
centered? To click on a hyperlink? And all the time keep in
mind that it is backdoored? Hmmm...



 Its unlikely to happen unless we start a campaign among the Free
 Software users of the world to make Flash free software.

That won't happen. Flash is the property of a corporation.
The only alternative I see is that this corporation would
donate the product, releasing all the sources and abandoning
all involved lawyer-crap. But that won't happen. I think
most companies better close away the stuff they won't develop
anymore instead of handing it over to a community.



 Yes, I know HTML 5 is just around the corner, but we've seen a
 concerted effort already (in the European Parliament at least) to
 introduce DRM into HTML 5 and though it may make using Flash marginally
 easier, it would be a retrograde step if DRM is to be introduced.

As far as I know, DRM will be covered by the upcoming standard.
This means it will be _possible_ to implement DRM solutions in
HTML. _Using_ them - that's a totally different field.

Keep in mind an important thing:

Alternatives for Flash have been around for a decade at least.
Video, audio, interaction - all possible without it. It's not just
about the browser plugin (the player), it's also about the
creative tools that people use to produce the stuff. Those tools
are offered usually in expensive commercially distributed suites.
As soon as developers and creators get aware of alternatives that
they can learn and use for free, they _might_ change, but only if
the mindset changes.

It's not just about those tools, it's also about file formats.
What I'm talking about is media codecs. Some of them offer DRM
capabilites, others don't. Some of them are highly infected with
patents and other lawyer-crap. There are reasons why some
systems and environments can play various formats out of the
box, and others can't. Which formats are efficient for use with
the Internet? Which offer scaling and streaming capabilities,
important for mobile users who demand lower quality, less data
transfer, and tolerance to higher latency? Which codecs can
make use of a decoder made in hardware?

_This_ problem also has to be solved!

Now put this back into relation with my initial idea of making
that kind of content decoder part of the web browser. The
same way you see a JPG image on a web page and click on a
hyperlink... It should be easy, but sadly it isn't.

HTML5 tries to solve those problems. Its markup will be better
suited for handling media content, plus CSS and JS will be
important players on the interaction field. There are already
projects that utilize those tools, and _developer tools_ as
well as _creator tools_ will be present. Maybe they will even
be present for free. YouTube can do fine without Flash already.
Online games in HTML5 are appearing. On the other hand, Flash
is a no-go on mobile, and mobile is becoming more and more
important to consumers. Additionally, more and more people
become aware of the danger of proprietary software (in regards
of privacy and corporate control, as well as an improving
understanding of what DRM does to their freedom). It will take
some time to show significant effect.

Let's hope people are going to get smarter than I assume. :-)



 So what are we left with?  Free software to replicate what Flash
 does (at least) that does not have the taint of proprietary software?
 Is that not an achievable goal?

It is a _desired_ goal.

Hi all,

   As far as I can tell, FreeBSD doesn't support suspend to disk on all
   architectures. On amd64 the necessary infrastructure doesn't exist,
and on
   i386 FPU state is lost, there is no multiprocessor support and some
MSRs are
   not restored [1].
  
   [1]: https://wiki.freebsd.org/SuspendResume

 Roland, sorry, no; you (and that page) are talking about Suspend to RAM,
 ACPI state S3.  What you've said is correct re Suspend to RAM - though
 some running amd64 have achieved some success on some machines lately;
 most of the issues are with restoring modern video, backlight and such.

 Those i386 comments don't apply to my Thinkpad T23s, which suspend and
 resume, in console mode and X, flawlessly on 9.1-R and properly after
 various tweaks on 8.x, 7.x and 6.x - but they're a single core P3-M ..

 I must reiterate, FreeBSD does not support Suspend to Disk (state S4 aka
 'hibernate') on ANY platform, except - perhaps - on machines supporting
 S4 in BIOS (hw.acpi.s4bios=1) which are very rarely spotted in the wild.

   And even suspend to RAM doesn't work on every machine [2].
  
   [2]: https://wiki.freebsd.org/IdeasPage#Suspend_to_disk

 That page IS about Suspend to Disk - but only as a wishlist idea, as it
 has been for many years.  Someone did take it on as a Google SoC project
 years ago, but nothing ever came of it to my knowledge.

 The last laptop I have that will properly hibernate - ie save RAM and
 all state to disk and power off, then reload all RAM and state on power
 return - is a 300MHz Compaq Armada 1500C (mfg '98), but using the older
 APM BIOS rather than ACPI.  (It's still running, 24/7/365 since 2002 :)

 cheers, Ian

Thanks Ian for clarifying that FreeBSD does not support Suspend to Disk. I
just assumed all major distros supported all the suspend states. Now I am
looking for a UPS that cleanly shuts down the machine when there is a power
outage.
I am looking at a APC Power-Saving Back-UPS ES 8 Outlet 700VA 230V AS
3112http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BE700G-AZtotal_watts=200tab=features,

Re: 9.1 VM nfs3 locks over VPN

2013-10-11 Thread Rick Romero

 Update - I've install a 9.1 VM locally, and I don't have the lock issue.
I've also allowed access straight over the internet, and locks don't work.
Now the non-working VM is not pristine like the test VM, but even so the
kernels appear to match based on uname,so I'm guessing it's a problem with
virtio block driver (which is not installed on the local test VM) or
something funky with the hosting providers virtualization.  Does that shed
any light on things?

Quoting Rick Romero r...@havokmon.com:


So let me explain my environment -
I have 1 FreeBSD 7.1 server, multiple Linux boxes, and a FreeBSD 9.0
server.  The 9.0 server is providing NFS3 mounts to all the other

systems.

I've built a remote VM (FreeBSD 9.1 offered by Hosting provider), and
connected it to my network via OpenVPN.  I copied my rc.conf from 9.0
server to 9.1 in order to grab the proper requirements for mount NFS3,

and

it worked fine until I ran my lock test (perl script).  Which really

sucks

because I've already gotten just about everything else I need working :(

I cannot get a lock from any OS on this side of the VPN.  There are no
errors logged anywhere, and adding rpcbind_flags=-l -L just tells me
that
the local servers are contacted. 
Oct 11 09:43:58 nl101 rpcbind: connect from 172.16.1.21 to
getport/addr(mountd)
Oct 11 09:44:07 nl101 rpcbind: connect from 172.16.1.21 to dump()
Oct 11 09:44:15 nl101 rpcbind: connect from 172.16.1.21 to
getport/addr(nfs)
Oct 11 09:44:16 nl101 rpcbind: connect from 172.16.1.21 to
getport/addr(mountd)
Oct 11 09:44:21 nl101 rpcbind: connect from 172.16.1.21 to
getport/addr(nlockmgr)
Yes lockd is running and the logs show a connection is made to it.  I

even

tried binding rpcbind to just the VPN IP.
What I couldn't do was enable debugging, the -d flag just caused rpcbind
to
hang.
So I'm currently here:

 I tried to contact the maintainer via email, but got no response.
 
 What would be the correct procedure for trying to get that port updated?
 
 1. Somehow get in contact with the maintainer. How? (I tried.)

A non-responding maintainer may be for any number of reasons
including having lost all interest, but sometimes they're just temporarily
unavailable (on holiday, busy with other things ...) and will get back to
it later.

 2. Try to become a maintainer. How?

Step one would be to try bringing the port up to date yourself,
sometimes it is as easy as editing the Makefile, changing the version and
running make makesum to update the checksums. Sometimes the patches need to
be adjusted in which case much depends on how much patching was needed in
the first place. In the case of asymptote it looks like the only patch is
adjusting the path to exampledir in Makefile.in which ought to be pretty
easy to handle.

The porters handbook has a lot of useful information on what to do
when things get tricky.

If you succeed in bringing the port up to date then your problem
is solved (you have an up to date version) and if you use send-pr to submit
the changes to bring it up to date then there's a good chance that you'll
solve the same problem for everyone else who may want it. 

 3. Something else?

Wait for someone else to do it.

FreeBSD is a volunteer project and the best way to make it better
is to scratch your itches and contribute the result.

  x11-toolkits/py-gnome-desktop.
  
  Unfortunately, it seems that going the normal route I shall have to 
  install 80! ports to get it. Is there an easier way?
 
 Actually I think you want x11-toolkits/gtk20..? Would pkg_add work for you?

Maybe graphics/librsvg2 is better suited (even though it's
version 2 of the library). The problem initially mentions
will remain: lots of installation dependencies. Sadly, that
seems to be normal today as modern software tends to rely
on layers of libraries of abstraction of tools of utilities
of stuff of layers of layers of other abstractions. :-)

As you see: gnome-desktop and gtk20. That should bring
your warning lights up: lots of dependencies ahead!

When you try to install a simple desktop environment, you'll
be confronted with hundreds of packages to be installed, some
of them you've probably never had thought of in regards of
what you need to install a desktop, such as two or more
different databases, LaTeX, translators, and other surprising
stuff. This will probably apply to most complex components and
parts of desktop environments or X11 toolkits (as mentioned
above).

As I mentioned, the librsvg2 port will install lib/librsvg-2.so.
It might require you to re-install your target application to
link against that library.

A library libsvg.so (without version number) doesn't seem to
be in the ports tree by that name.

My lazy man's method of searching what port might contain the
library: Midnight Commander, go to /usr/ports, Meta-?, seach
in pkg-plist, search for text librsvg and examine the
results with PF3. This method relies on approaches that might
be wrong... :-)

Note that my (locally installed) ports tree is not up to date
anymore so you should consider performing a search on a recent
tree to make sure I didn't miss anything.

 2. Try to become a maintainer. How?

   Step one would be to try bringing the port up to date yourself,
 sometimes it is as easy as editing the Makefile, changing the version
 and running make makesum to update the checksums. Sometimes the
 patches need to be adjusted in which case much depends on how much
 patching was needed in the first place. In the case of asymptote it
 looks like the only patch is adjusting the path to exampledir in
 Makefile.in which ought to be pretty easy to handle.

   If you succeed in bringing the port up to date then your problem
 is solved (you have an up to date version) and if you use send-pr to
 submit the changes to bring it up to date then there's a good chance
 that you'll solve the same problem for everyone else who may want it.

Sounds reasonable. I think I'll give this a try once 10.0 is officially
out.

   FreeBSD is a volunteer project and the best way to make it
 better is to scratch your itches and contribute the result.

It would be interesting to know how the number of volunteers has changed
during the past couple of years.

Thanks!

  -p10 through -p12 probably didn't involve any kernel changes. Bumping the

  new kernel.
 
 That there's no kernel changes doesn't mean that uname -a info is not
 updated. 

You are incorrect. The output of uname -a is taken from the kernel and
cannot be updated without installing a new kernel.

The good news is that FreeBSD 10 will ship with a new utility called
freebsd-version which will provide a better way of identifying if your
system is up to date.

From the commit message:

Introduce the /libexec/freebsd-version script, which is intended to be
used by auditing tools to determine the userland patch level when it
differs from what `uname -r` reports.  This can happen when the system
is kept up-to-date using freebsd-update and the last SA did not touch
the kernel, or when a new kernel has been installed but the system has
not yet rebooted.

http://svnweb.freebsd.org/base/head/bin/freebsd-version/


By the way, it will be /bin/freebsd-version as it has been relocated
since the import into head.

Re: Geli and ZFS

 Generally, it's recommended to let ZFS manage the whole disk if possible,

 I will be using couple of 3TB HDDs mirrored for data and want to encrypt

IIRC, there is/was a major performance-difference on Solaris between using ZFS 
on a partition, or a whole disk.  FreeBSD is happy with either.

The two alternatives you mentioned were:

ZFS over GELI over disk
and
ZFS over GELI over ZFS over disk

While ZFS wouldn't get the raw disk in setup #1, the left-most ZFS wouldn't get 
it in the second scenario either.

 I am hoping someone with an in-depth understanding of ZFS will be able to
 offer some insight.


What I usually do and recommend is using GPT with labels for the partitions 
you'll put GELI/ZFS on.

There's a couple of different reasons for this:

 * It'll let you create your zpool on /dev/gpt/label, which will make it easy 
to find even when the device moves (harddisk-renumbering, changes from internal 
ATA to USB enclosure… )

 * You don't run things through ZFS twice.

 * The disk is fully encrypted.

 * etc

Hi,

I've a Seagate constellation ES.2 which supports 4K sectors but diskinfo shows

I understand that Seagate ships these drives to be compatible with 512byte 
sectors so that older Windows OSs work on the.

But I'm unsure how to get this drive to report as having 4K sectors.


It does not need to report that, as long as the partitions are aligned 
to 4K blocks.  Seagate has some auto-alignment tech that seems 
reasonably effective.  I'd still make sure the partitions are aligned.



I'm really asking from a ZFS perspective as my vdevs show with an ashift of 9 
via the zdb command.

I'd rather forgo the gnop hack as I prefer a cleaner approach.


Using gnop is the way to force ZFS to use 4K blocks at present.  And 
this does not guarantee alignment with 4K disk blocks, which must be 
accomplished with partition alignment.

 I cannot use gmirror with these servers because a) if no MPT RAID is

 RAID *is* configured in BIOS setup, it occupies the last sector and
 prevents GEOM from working with these drives. 
 
 Any help please? (or redirect me to a more appropriate maillist).

After many unsuccessful trials and googling, we had to reconfigure the
adapter from RAID mode to IT mode. It required flashing the adapter's
BIOS from a Supermicro-supplied image and changing a jumper setting on
the motherboard. 

Now as the adapter is in IT mode, it is a plain HBA the BIOS can
boot from, and I have set up a gmirror on the SAS disks.

After flashing the adapter BIOS, don't forget to enter its setup

Thank you,

Hello,

ipfw always has one default rule, standard is

65535 deny ip from any to any

If you set net.inet.ip.fw.default_to_accept=1, you get

65535 allow ip from any to any

instead.


Specifing firewall_type=OPEN gives you an additional rule

65000 allow ip from any to any


Now, if for example you execute ``ipfw flush'', thus deleting all rules,
this deletes rule 65000, but the default rule stays in effect.
With ...default_to_accept=0 ( standard setting ) you now have disabled  
all network connections and locked yourself out if you're working remote.
