[Tiff] tiffcrop tool ~ JPEG compression options produce wrong output
The tiffcrop is inverting RGB and YCbCr output when using jpeg compression. The stated YCbCr default (no format specified) works correctly: 'tiffcrop -c jpeg infile.tiff outfile.tif' the output is a YCbCr file (default behavior) 'tiffinfo outfile.tif' 'Photometric Interpretation: YCbCr' But if we request a specific mode using the proposed 'rgb' and 'raw' jpeg options: 'tiffcrop -c jpeg:raw infile.tiff outfile.tif' the output is a RGB file 'tiffinfo outfile.tif''Photometric Interpretation: RGB color' 'tiffcrop -c jpeg:rgb infile.tiff outfile.tif' the output is a YCbCr file 'tiffinfo outfile.tif' 'Photometric Interpretation: YCbCr' When we request RGB a YCbCr file is produced, when YCbCr is requested a RGB file is produced. This has been reported 2 years ago as Issue #228, but still not addressed. Is this considered of lesser importance? I would certainly fix it if I knew how to do it... I know that the work on libtiff is voluntary, which I very much appreciate and am grateful for. I just thought I would leave a reminder here, in case the issue had just been inadvertently buried in time. tiffcp does not suffer from this drawback. ___ Tiff mailing list Tiff@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/tiff

Re: [Tiff] Building libtiff with WEBP support
I found a temporary way of doing this without editing the source.
On cmake command line:
-DCMAKE_PROJECT_INCLUDE=my_include_file
‘my_include_file’ has the following contents:
link_libraries("C:/build/lib/libsharpyuv.lib")
This is not very elegant, because it inserts the library as a dependency of all
targets, not just the ‘tiff’ one, but for now it seems to work without
undesirable secondary effects.

[Tiff] Building libtiff with WEBP support
Salutations to all
Due to some recent changes in the WEBP source code, building the dynamic
libtiff library with WEBP support started giving the following error messages:
libwebp.lib(picture_csp_enc.obj) : error LNK2001: unresolved external symbol
SharpYuvConvert [C:\Build\bin\libtiff\libtiff\tiff.vcxproj]
libwebp.lib(picture_csp_enc.obj) : error LNK2001: unresolved external symbol
SharpYuvGetConversionMatrix [C:\Build\bin\libtiff\libtiff\tiff.vcxproj]
libwebp.lib(picture_csp_enc.obj) : error LNK2001: unresolved external symbol

C:\Build\bin\libtiff\libtiff\Release\tiff.dll : fatal error LNK1120: 3
unresolved externals [C:\Build\bin\libtiff\libtiff\tiff.vcxproj]
This is related to the introduction of a new library in WEBP, libsharpyuv.lib.
I solved the problem by appending the following to the end of
libtiff/libtiff/CMakeLists.txt:
if(WEBP_SUPPORT)
target_link_libraries(${PROJECT_NAME} PRIVATE "C:/build/lib/libsharpyuv.lib")
endif()
or including the line in the relevant WEBP section (starting with line 148):
if(WEBP_SUPPORT)
target_link_libraries(tiff PRIVATE WebP::WebP)
string(APPEND tiff_requires_private " libwebp")
target_link_libraries(${PROJECT_NAME} PRIVATE "C:/build/lib/libsharpyuv.lib")
endif()
With this line, libtiff builds and works correctly.
But having to edit the file by hand each time is not very elegant and I would
like to find a definitive solution. I tried to pass the instruction on the
cmake command line, but I couldn’t find a working solution.
Better still would be someone with the necessary programming knowledge to come
up with a permanent solution on the original libtiff code. I am not a
developer, I am a libtiff user with just enough knowledge to compile it myself
and lightly modify code to solve basic issues.
I can also introduce the reference to libshrpyuv in Microsoft Visual Studio,
under Linker/Input/Additional Dependencies, but I mostly prefer to build from
the command line using cmake.
Any tips would be appreciated.
Thank you.

So far you have not provided stats on server usage (cpu,ram) over a 24hour or 7 day 8am-5pm timeframe. So I will asume you have plenty of usage/performance to spare. Yes, I do. Unless using SSDs when creating the VM pleae do not use dynamic disk allocation. MS SQL may be very intensive and you are already sharing resources, lets not be the i/o intensity of the expanding disk one of them.

[CentOS] File server as host for a Windows Server VM?
I hope that someone here can give some advice on the following: I have a Samba based Active Directory. A CentOS 7.6 machine runs as a file server and hosts the Windows user profiles for all the Windows workstations. Now management has decided that they need a Windows server for a couple of administrative applications, which need MS SQL Server. That would be the only role of this Windows. Since the above mentioned server has enough resources (2x Quad Core Xeon 2.66 GHz with HT and 48 GB of RAM, a dual port 10 Gb NIC) I thought of making it a host for a Windows virtual machine using KVM. Given the resources and current setup we have, at the moment it wouldn't be practical to implement both servers as VMs on top of a bare metal hypervisor.

Under CentOS, for example, I find the following directories: /dev/disk/by-id /dev/disk/by-path /dev/disk/by-uuid Each one has its optimal use case. It seems to me that in general the ideal would be to use the WWN identifier, which now comes printed on the disk label sticker and uniquely identifies the disk, offering a clear correspondence between physical and logical disks. Under CentOS, the WWN ID of detected disks can be found under /dev/disk/by-id. WWN stands for "World Wide Name". There's a Wikipedia article about it here: https://en.wikipedia.org/wiki/World_Wide_Name "hdparm - I" or even "smartctl -a" will show which /dev/sdX or whatever corresponds to which WWN or other relatively stable ID types. The advantage of WWN is that the ID won't change if you connect the disk to a different controller, for example from a SAS one to a SATA one. In one of my servers, if I unplug a SATA disk from a LSI-Avago SAS controller and I connect it to a Intel onboard SATA controller the ID changes from "scsi-idnumber" to "ata-brand-model-serialnumber" but the WWN remains constant. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

However, the latest C7 server I built, ran into problems with them on on a Intel C236 board (SuperMicro X11SSH) with tons of "ata bus error write fpdma queued". Googling on it threw up old suggestions to limit SATA link speed to 1.5Gbps using libata.force boot options and/or noncq. Lowering the link speed helped to reduce the frequency of the errors (from not getting a smartctl output to getting a complete listing within 2 tries).

Re: [CentOS] OT hard disk geometry
It seems to me that there's some confusion on your part about what a SATA power connector is... The SATA edge connector is divided in two parts, a larger one and a narrower one. The narrower one is the signal, or data, connector. The larger one is the power connector. Some older drives also had an additional common Molex connector for power, for compatibility reasons, since at first only a few power supplies had the SATA power connector. Note that the Molex connector does not enable the hot-plugging and unplugging of SATA drives. This needs the 3.3V supply that only the SATA connector provides. As far as I can see, the ST3250318AS does not have such a connector. The manual for the ST3250318AS is here: http://www.seagate.com/staticfiles/support/disc/manuals/desktop/Barracuda%207200.12/100529369b.pdf On page 28 you can read about the SATA cables and connectors. The pins you refer to, which are not present on the WD at the same position, are NOT power connections, that is a jumper block as you can read on the first image of page 28. The manual states the following: « It is usually not necessary to set any jumpers on the drive for proper operation; however, if you connect the drive and receive a “drive not detected” error, your SATAequipped motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation. If you have a motherboard or host adapter that does not support autonegotiation: -Install a jumper as shown in Figure 1 below to limit the data transfer rate to 1.5 Gbits per second (and leave the drive connected to the SATA-equipped motherboard or host adapter that doesn’t support autonegotiation) or -Install a SATA host adapter that supports autonegotiation, leave the drive jumper block set to “Normal operation” (see Figure 1 below), and connect the drive to that adapter. This option has the benefit of not limiting the drive to a 1.5 Gbits/sec transfer rate. » I think this is not a power connector issue. The WD is a SATA3 drive (6gb/s). Are you sure that your motherboard supports SATA3 drives? Maybe SOME ports support them while others do not? If not, can you force the WD to operate in a lower mode? Some drives can, either by hardware or software. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [Samba] RPM building tools for Samba 4.0.3 on RHEL 6 published bye me on Github
Regarding your latest samba.spec for version 4.0.4-0.1
If with_dc is activated, the build still fails with:
RPM build errors:
Installed (but unpackaged) file(s) found:
/usr/lib64/samba/ldb/ildap.so
As I reported before, there is an entry for ldbsamba_extensions.so
under # ldb libraries built with DC activated but not for ildap.so.
The file gets built but not packaged.
Also, the installation of the samba-libs package fails with:
error: Failed dependencies:
libdfs_server_ad.so()(64bit) is needed by
samba-libs-0:4.0.4-0.1.el6.x86_64
libdfs_server_ad.so(SAMBA_4.0.4)(64bit) is needed by
samba-libs-0:4.0.4-0.1.el6.x86_64
The query rpm --query --requires -p
samba-libs-4.0.4-0.1.el6.x86_64.rpm gives libdfs_server_ad.so as a
requirement.
Is there any reason why my previous suggestion to package
libdfs_server_ad.so in samba-libs instead of samba-dc-libs was not
accepted?
If you do that, under the condition %if %with_dc, the error
disappears. Please note that samba-libs must always be installed
before samba-dc-libs, so that the samba-dc-libs requirement at
install has already been satisfied by samba-libs.
As also reported before, the same happens with libposix_eadb.so. It is
required by samba. I suggested that it be moved to the same section as
libdfs_server_ad.so, i.e. in samba-libs under %if %with_dc.
If these two steps are taken, both build and install complete flawlessly
and you get a working AD DC installation.
If this is accepted, as a final touch and for the sake of consistency,
the %exclude for /libdfs_server_ad.so should go into LIBS, under
%if %with_dc:
%else
# formerly excluded in files dc
%exclude %{_libdir}/samba/libdfs_server_ad.so
%endif # with_dc
and the %exclude for /ildap.so and ldbsamba_extensions.so should

Re: [Samba] RPM building tools for Samba 4.0.3 on RHEL 6 published bye me on Github
I tested the .spec file you posted today. There's still a glitch remaining. If built with the file as it is (%global with_dc 0) the packages build cleanly. However, if %global with_dc 1 is used, the build fails with the following error: RPM build errors: Installed (but unpackaged) file(s) found: /usr/lib64/samba/ldb/ildap.so I can see that this file is excluded in the packging list pertaining to DC-LIBS, if with_dc is disabled but it is not one of the # ldb libraries built with DC activated, contrary to the other file always excluded in the Fedora .spec (ldbsamba_extensions.so), which is listed in your file. When I do a rpm query for --whatrequires both files, the answer is that no package requires either file. As such, they should probably be always excluded, as happens with the Fedora .spec file. One more thing: since Samba 4.0.4 is out now, maybe you should update your files to match? This is just a security release that presents no problem whatsoever when built with the same specs as 4.0.3.

I forgot something.
%{_libdir}/samba/libdfs_server_ad.so
%{_libdir}/samba/libposix_eadb.so
As I said before, those two entries MUST be within ### LIBS, under
%if %with_dc. Otherwise, the build completes cleanly but the install
process of samba-libs and samba fails with the following:
error: Failed dependencies:
libdfs_server_ad.so()(64bit) is needed by
samba-libs-0:4.0.4-1.el6.x86_64

libposix_eadb.so(SAMBA_4.0.3)(64bit) is needed by
samba-0:4.0.3-0.6.el6.x86_64
I suggest doing the described inclusions and, for the sake of
consistency, moving the correspondent exclusion to the same section:
### LIBS
%if %with_dc
%{_libdir}/samba/libdfs_server_ad.so
%{_libdir}/samba/libposix_eadb.so
%else
# formerly excluded in files dc
%exclude %{_libdir}/samba/libdfs_server_ad.so
%endif # with_dc
If these steps are taken, everything builds and installs correctly,
whether AD DC is activated or not.
The Fedora .spec file excludes samba/libdfs_server_ad.so from the
build process altogether because Fedora is not using the AD DC component
of Samba 4 due to lack of support with MIT Kerberos.

On the matter of the release of Samba 4.0.4, shouldn't the Obsoletes
statement now include the form Obsoletes: samba %{samba_depver}
instead of only Obsoletes: samba4 %{samba_depver}? You now need to
Obsolete all versions of Samba 4 prior to 4.0.4, both release and
pre-release.
Also, I think that the form you are still using for Provides (for
example Provides: samba4-common = %{samba_depver}) is no longer
correct. According to the Samba team conventions, after the release of
Samba 4 the form should now be Provides: samba-common = %{samba_depver}.
In a previous mail to you, I suggested:
Provides: samba = %{samba_depver}
Conflicts: samba4 %{samba_depver}
Obsoletes: samba %{samba_depver}
I used Conflicts for samba4 because there are significant
differences between the pre-release and the release versions.
Or maybe we could use two Obsoletes statements instead...

Re: [Samba] Samba4 Compile Error
Definitely update to RHEL 6.4, if possible, and consider working from
my samba-4.0.3 backports at: https://github.com/nkadel/samba4repo This
is designed to check out all the other needed dependencies, and work
from there to build up a local yum repository with all the necessary
libtdb, libldb, iniparser, and other dependencies.
I just had a look at the latest changes you did. I am glad that you
included a samba.init file.
It was a nice touch.
I used your latest samba.spec to build the packages and I found that
there are still a few issues to be solved:
If %global with_dc 0 is used, the build fails with the following result:
RPM build errors:
Installed (but unpackaged) file(s) found:
/usr/lib64/samba/ldb/ildap.so
/usr/lib64/samba/ldb/ldbsamba_extensions.so
/usr/lib64/samba/libdfs_server_ad.so
I used the following additions:
### DC-LIBS
%if %with_dc
# ldb libraries built with DC activated
%{_libdir}/samba/ldb/ildap.so
%{_libdir}/samba/ldb/ldbsamba_extensions.so
%else
%exclude %{_libdir}/samba/ldb/ildap.so

required order gives the following errors:

libposix_eadb.so(SAMBA_4.0.3)(64bit) is needed by
samba-0:4.0.3-0.6.el6.x86_64
To avoid a dependence nightmare, samba-libsand samba must be
installed before samba-dc-libs and samba-dc.
As such, the former two cannot depend on the later to satisfy their
requirements. Maybe the following should be included
under LIBS?
### LIBS
%if %with_dc
%{_libdir}/samba/libdfs_server_ad.so
%{_libdir}/samba/libposix_eadb.so
%else
%exclude %{_libdir}/samba/libdfs_server_ad.so
%endif # with_dc
I don't really know if some the above files are in fact needed even when
DC is off, so I did the above configuration experimentally for my own
use and everything built and installed correctly.

Re: [Samba] windows 7 roaming profiles
Isn't there a way with group policies to have the client delete the roaming profile after the user logs out. I think that would solve the OP''s problem. Yes, there's a way to do that. But it doesn't solve the problem of having to transfer maybe hundreds of megabytes or even worse each time you log in to the domain. Back when the idea of roaming profiles was first put to practice (Windows 2000), user profiles were MUCH smaller than they are today. So, the use of roaming profiles with folder redirection seems to me the most appropriate way to deal with this.

Re: [Samba] windows 7 roaming profiles
NO, IT DOESN'T! Microsoft disagrees - see below. You are introducing a new theme altogether: Offline Files. On a local and *reliable* network, you can use folder redirection *without* Offline Files. I did it and it works. What you describe is the behavior of normal *roaming profiles*. No... you can use a combination of roaming profiles and redirected folders for the best result, which is what I do. That's precisely what I was advocating. Please read my posts. The stuff in t he roaming profiles (very little) is copied back/forth at login/out, the stuff in t he redirected folders is *synchronized* at all times using the Offline Files technology that has long existed in Microsofts products. Maybe you were not very clear in your first post. You said the following: Folder Redirection will always (...) store local cached copy of those folders on the local computer... what it accomplishes is it saves all of the copying back and forth when logging in/out. which is not true. Even with Offline Files, only the files you are working with will be synchronized back and forth. The redirected folders themselves and the files previously stored therein will not be transferred to the client machine. This makes a big difference because we may be talking about Gigabytes of data. A roaming profile without folder redirection does transfer the whole profile, which might have been a good idea a decade ago but is not feasible with the amounts of data we work with today. Yes, but they will *also* reside on the *local computer*. As I said before, only the files you are modifying will have a local instance, which will be synchronized to the server at logout. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

Re: [Samba] windows 7 roaming profiles
2. Is it correct that the profile files are not synced until the user logs off? That is the correct working of roaming profiles.

Re: [CentOS] Software RAID1 with CentOS-6.2
A few months ago I had an enormous amount of grief trying to understand why a RAID array in a new server kept getting corrupted and suddenly changing configuration. After a lot of despair and head scratching it turned out to be the SATA cables. This was a rack server from Asus with a SATA backplane. The cables, made by Foxconn, came pre-installed. After I replaced the SATA cables with new ones, all problems were gone and the array is now rock solid. Many SATA cables on the market are pieces of junk either incapable of coping with the high frequencies involved in SATA 3Gb/s or 6Gb/s or their connector are made of bad quality plastics unable to keep the necessary pressure on the contacts. I had already found this problem with desktop machines, I simply wouldn't believe that such a class of hardware would exhibit it also. So, I would advise you to replace the SATA cables with good quality ones. As an additional information, I quote from the Caviar Black range datasheet: Desktop / Consumer RAID Environments - WD Caviar Black Hard Drives are tested and recommended for use in consumer-type RAID applications (RAID-0 /RAID-1). - Business Critical RAID Environments – WD Caviar Black Hard Drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications.

It may seem paradoxical but it's not. It just *works* after a very simple and quick installation. The user only has to answer a couple of simple questions. A WAN interface and a LAN interface are ready and working together and that's it. It can be installed on anything, from a Compact Flash card to a USB sticker, it doesn't even need a hard disk. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] How to setup a computer using CentOS6 as a firewall for the whole network in my place?
pfsense for a newbie? A CentOS-like firewall would be ClearOS (formerly Clarkconnect) and again would reduce the number of simultaneously-learned layers to wade through. While it works very well, it is yet another layer and difference to learn, and when learning is is really good to not overload the number of layers to learn at once. IMHO, YMMV, etc. Since I have done cisco IOS stuff for a decade and a half, now, I'd recommend Vyatta over pfsense, but, there again, it is yet another, different, layer to learn that *will* overwhelm a newbie. Isn't Vyatta a comercial product? I suppose that it wouldn't fit a newbie either... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] How to setup a computer using CentOS6 as a firewall for the whole network in my place?
Why does it have to be CentOS? If you want a wonderful router/firewall that you can have up and running in a few minutes, you should look at this: www.pfsense.org I quote from their website: pfSense is a free, open source customized distribution of FreeBSD http://www.freebsd.org tailored for use as a firewall and router. In addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features and a package system allowing further expandability without adding bloat and potential security vulnerabilities to the base distribution. If you insist in using Linux instead, you could look at this: www.ipcop.org Once again, a distro specialized on the function it performs. Why have a generic and bloated system that you then have to customize from scratch when such wonderful specialized projects already exist? I use Linux servers and a pfsense firewall to protect the network.

Re: [Samba] Samba 3.6.1 losing browser elections to WinXP
2) How can I force a browser election without restarting the daemons? smbd doesn't seem to respond to a SIGHUP. A command line would be nice. Look at the smbcontrol command. os level = 65 Did you try to increase os level ? Also, read the man page for the domain master parameter. From smb.conf man page: preferred master (G) This boolean parameter controls if nmbd(8) is a preferred master browser for its workgroup. If this is set to yes, on startup, nmbd will force an election, and it will have a slight advantage in winning the election. *It is recommended that this parameter is used in conjunction with domain master = yes, so that nmbd can guarantee becoming a domain master.* -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
Re: [Samba] Incorrect domain SID when creating new users
I created a new user on our Samba domain master yesterday but the user was unable to login from WinXP to the domain. I think they got an error that a device connected to the system wasn't working. The user was created using smbldap-useradd. (...) The question is where do I set the domain SID? I remember doing it at some stage when I set-up the samba domain but I have forgotten. The SID number is configured in /etc/smbldap-tools/smbldap.conf smbldap-tools comes with a script to assist in the basic configuration of the tools. It's called configure.pl in most versions but the name was recently changed to smbldap-config.pl At least in RedHat-alike distros, the script resides in /usr/share/doc/smbldap-tools-x.x.x, where x.x.x is your particular version.

Re: [CentOS] weird XFS problem
Now the machine is not particularly powerful: it is 64-bit machine, dual core CPU, 3 GB RAM. So perhaps this is a factor in why I am having the following problem: once in awhile that XFS partition starts generating multiple I/O errors, files that had content become 0 byte, directories disappear, etc. Every time a reboot fixes that, however. So far I've looked at logs but could not find a cause of precipitating event. Is the CentOS you are running a 64 bit one? The reason I am asking this is because the use of XFS under a 32 bit OS is NOT recommended.

Re: [CentOS] weird XFS problem
You are right - it would indeed be desirable to have more than 3 GB of RAM on that system. However it is not obvious to me that having that little RAM should cause I/O failure? Why? That it would make the machine slow is to be expected - and especially so given that I had to jack the swap up to some 40 GB. But I do not necessarily see why I should have outright failures due solely to not having more RAM. If I were you, I would be monitoring the system's memory usage. Maybe some software component has a memory leak which keeps worsening until a reboot cleans it. Also, I wouldn't discard the possibility of a physical memory problem.

If these attributes are set, the user does not connect to his home service. The homedir needs to be only in smb.conf. I must add that, according to documentation, the home directory LDAP attributes need only to be set for a particular user if they differ from the general setting. Quoting from The Official Samba 3.5 HOWTO: « 11.4.4.8 LDAP Special Attributes for sambaSamAccounts The sambaSamAccount ObjectClass is composed of the attributes shown in next tables: Part A, and Part B. The majority of these parameters are only used when Samba is acting as a PDC of a domain (refer to Domain Control, for details on how to configure Samba as a PDC). The following four attributes are only stored with the sambaSamAccount entry if the values are non-default values: • sambaHomePath • sambaLogonScript • sambaProfilePath • sambaHomeDrive These attributes are only stored with the sambaSamAccount entry if the values are non-default values. For example, assume MORIA has now been configured as a PDC and that logon home = \\%L\%u was defined in its smb.conf file. When a user named ‘becky’ logs on to the domain, the logon home string is expanded to \\MORIA\becky. If the smbHome attribute exists in the entry ‘uid=becky,ou=People,dc=samba,dc=org’, this value is used. However, if this attribute does not exist, then the value of the logon home parameter is used in its place. Samba will only write the attribute value to the directory entry if the value is something other than the default (e.g., \\MOBY\becky). » -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
