[CentOS] CentOS 6 - Support for CanoScan LiDE 210

2015-09-26 Thread Meikel 

Hi folks,

for some time I used a HP 2840 AiO device, connected via LAN, to scan 
documents. As scanning application I use xsane. I want to replace that 
HP scanner by a CanoScan LiDE 210.


# LANG="" yum info libsane-hpaio

(from HPOJ).


Now I connected CanoScan LiDE 210 Scanner via USB cable to my CentOS 6 
workstation.

After opening xsane it seems to be connected to the HP Scanner. I can 
not find any options for choosing another scanner device. From 
http://www.sane-project.org/sane-mfgs.html  I can see that CanoScan LiDE 
210 is supported by genesys 1.0-63. From my understanding on CentOS the 
genesys backend is included in sane-backends:

The sane-backends is installed, but I can not "see" the scanner:

# scanimage -L
device `hpaio:/net/HP_Color_LaserJet_2840?zc=NPI9AC264' is a 
Hewlett-Packard HP_Color_LaserJet_2840 all-in-one


I have no idea what I can do now. It is not clear to me if sane-backends 
package really includes the required genesys 1.0-63 version.


Any help to make the new scanner work is appreciated.

is it enabled in dll.conf ?



As far as I can see, it is enabled there:

You need sane-backends 1.0.22 or later to have genesys 1.0-63.

There are a few ways to install a newer version of sane-backends on
EL6. One is to rebuild a src.rpm from Fedora. The other is to use the
linuxtech-backports repo [1]. I have even built it from a tarball but
this should not be necessary.

If you need more assistance, let us know.

I was not able to confirm that this particular model is supported. I
understand you see the errors but is the mouse/touchpad actually
working?

If this is a problem with the psmouse module, you could try reloading it:

modprobe -r psmouse

modprobe psmouse

For the time being you can still get samba 4.2 packages and run Samba AD on

The paid service is only for 4.3+ so you should be good for a while.

[CentOS-virt] CentOS 6 Xen virt* issues

2015-09-26 Thread Pasi Kärkkäinen 
Hello,

I just upgraded some of my el6xen boxes to latest CentOS 6.7, Xen 4.4.3 and 
dom0 3.18.17 rpms, and noticed these new problems:


1) virt-manager fails to start with an error: "D-Bus library appears to be 
incorrectly set up; failed to read machine uuid: Failed to open 
"/var/lib/dbus/machine-id": No such file or directory"

And indeed.. there was no such file. Running command "dbus-uuidgen --ensure" 
fixed it, and virt-manager starts OK after that. So this was more for the 
mailinglist archives, if someone else meets the same issue.


2) virt-viewer doesn't work anymore. 

It seems in el6.6 virt-viewer was version 0.6.0-11, but now in el6.7 it's 
2.0-7, with a lot of changes..

If I try to use virt-viewer and run "virt-viewer " command, I get an 
error popup dialog saying "Failed to connect: Display can only be attached 
through libvirt with --attach".

verbose debug output:


# virt-viewer -v --debug -c "xen://" testvm

So it seems both connection types/methods now fail.. I'm not sure if the issue

I followed Frank's procedure on my C6 system, a year or two ago, and

Seems a packaging issue ? From where is your rpm for backuppc coming ?
/var/run on EL7 is in fact pointing to /run , which is tmpfs, so
packages aren't supposed to drop something there directly, or that
will be gone anyway next time your restart the machine.
Workaround for those not-yet-fixed-for-systemd-packages : man
tmpfiles.d (that will create/maintain those)

And third issue aswell:

3) Creating an HVM guest using virt-manager with file-based storage uses 
loopback-mount, not blktap

When I manually create a new Xen HVM guest using virt-manager, and choose 
file-based image for storage of the VM, it seems to be set up to use file: 
backend/driver with loopback-mounted image file:


  
  
  
  


# losetup -a
/dev/loop0: [fd00]:1709109 (/var/lib/libvirt/images/testvm2.img)

With earlier versions of rpms similar setup used blktap2 backend.. (and yes, I 
do have blktap module loaded in dom0 kernel).

[CentOS] Is this a bug in CentOS-7 BackupPC?

2015-09-26 Thread Timothy Murphy 
When I try to start BackupPC with "sudo systemctl restart backuppc"
on my CentOS-7 server (running kernel 3.10.0-229.14.1.el7.x86_64)
I get the following error in /var/log/BackupPC/LOG

  2015-09-26 13:58:14 Reading hosts file
  2015-09-26 13:58:14 unix bind() failed: No such file or directory

This message occurs in the Perl script /usr/share/BackupPC/bin/BackupPC :

  my $sockFile = "/var/run/BackupPC/BackupPC.sock";
  unlink($sockFile);
  if ( !bind(SERVER_UNIX, sockaddr_un($sockFile)) ) {
print(LOG $bpc->timeStamp, "unix bind() failed: $!\n");
exit(1);
}

As far as I can see (I'm no guru) this is trying to open a unix socket 
with the name /var/run/BackupPC/BackupPC.sock .

There is no directory /var/run/BackupPC/ on my server.
When I create this, setting backuppc.apache as owner,
and run "sudo systemctl restart backuppc"
I see in /var/log/BackupPC/LOG that BackupPC has (at long last) started

I don't really understand this.
The perl script wants to create /var/run/BackupPC/BackupPC.sock
which it seems it cannot do unless /var/run/BackupPC/ exists.
If as you say this disappears on re-booting,
I don't see how this program could work.

Seems like a packaging bug in EPEL.  Fedora does this (semi-)right, by
dropping down an /etc/tmpfiles.d/BackupPC.conf, which instantiates the
/var/run/BackupPC directory as 0755 root:backuppc.

Looking at the epel7 specfile, I see:

# tmpfiles.d & systemd support in all supported Fedora now, but not RHEL
%if 0%{?fedora}
%global _with_tmpfilesd 1
%global _with_systemd 1
%endif

and then later:

%if 0%{?_with_tmpfilesd}
install -d $RPM_BUILD_ROOT/%{_sysconfdir}/tmpfiles.d
install -p -m 0644 %{SOURCE6}
$RPM_BUILD_ROOT/%{_sysconfdir}/tmpfiles.d/%{name}.conf
%endif

and 

%if 0%{?_with_tmpfilesd}
%config(noreplace) %{_sysconfdir}/tmpfiles.d/%{name}.conf
%endif

Of course, CentOS7 (and RHEL7) supports tmpfiles.d, in fact, may
system services require it, such as cups, samba, pam, etc.  I'm not
sure why the BackupPC package installs it in /etc/tmpfiles.d instead
of /usr/lib/tmpfiles.d, probably because the person who made the
package isn't very systemd-saavy.

The contents of the /etc/tmpfiles.d/BackupPC.conf file looks like
this: 

D /var/run/BackupPC 0775 root backuppc -

If you create that file, you'll get the /var/run/BackupPC file when
you start up.  I suggest filing a bug against the EPEL package if you
want to get it fixed there.
