CentOS 6 - Support for CanoScan LiDE 210
by Meikel 30 Sep '15

30 Sep '15

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 ... Installed Packages Name : libsane-hpaio Arch : x86_64 Version : 3.14.6 Release : 3.el6 Size : 148 k Repo : installed From repo : base Summary : SANE driver for scanners in HP's multi-function devices URL : http://hplip.sourceforge.net/ License : GPLv2+ Description : SANE driver for scanners in HP's multi-function devices (from HPOJ). Now I connected CanoScan LiDE 210 Scanner via USB cable to my CentOS 6 workstation. # dmesg | tail --lines=15 ... usb 3-1: new high speed USB device number 8 using xhci_hcd usb 3-1: New USB device found, idVendor=04a9, idProduct=190a usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 3-1: Product: CanoScan usb 3-1: Manufacturer: Canon usb 3-1: configuration #1 chosen from 1 choice ... 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: # LANG="" yum info sane-backends ... Installed Packages Name : sane-backends Arch : x86_64 Version : 1.0.21 Release : 3.el6 Size : 4.4 M Repo : installed From repo : anaconda-CentOS-201410241409.x86_64 Summary : Scanner access software URL : http://www.sane-project.org License : GPLv2+ and GPLv2+ with exceptions and Public Domain Description : Scanner Access Now Easy (SANE) is a universal scanner interface. The : SANE application programming interface (API) provides standardized : access to any raster image scanner hardware (flatbed scanner, : hand-held scanner, video and still cameras, frame-grabbers, etc.). 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. Regards, Meikel

Question maybe off topic
by Jerry Geis 29 Sep '15

Is there something in CentOS/linux that would take a single input in my case RS232 port and deliver that to two connecting network ports? So two devices can get the single port data. Thanks, Jerry

[OT] linux on a PPC (mac mini)
by wwp 29 Sep '15

29 Sep '15

Hello there, complete off-topic, sorry about this, but my former idea was to install a CentOS on an old mac mini (PPC!). Disappointed to see that PowerPC is not a supported architecture and that non ARM or Intel architecture are not managed by recent distros.. :-(. Searching the web, I see very few possibilities to install a recent (I need gnome2) GNU/Linux distro on such hardware. I gave Linux MintPPC 11 (http://www.mintppc.org/content/list-macs) a try, but the netinstall iso simply fails in installing a boot loader that conserves the original OS/X partition even after many tries and workarounds. Any hint or experience would be welcome? Regards, -- wwp

Mate-update breaks locale
by johan.vermeulen7＠telenet.be 29 Sep '15

29 Sep '15

Hello All, today's Mate-updates seem to have removed our nl_be locale. We run Mate desktop on some 15 Centos7 laptops. Not so big a deal, we can easily switch to nl_nl or people would still figure it out in English. But maybe for other, not so common locales, you might want to check before updating. Greetings, Johan

httpd userdir problem
by Timothy Murphy 28 Sep '15

28 Sep '15

I'm running httpd-2.4.6-31.el7.centos.1.x86_64 under CentOS-7 (kernel 3.10.0-229.14.1.el7.x86_64). I cannot get the httpd userdir facility working; when I try to access localhost/Menloe I get the message "You don't have permission to access /Menloe on this server." I see in /var/log/httpd/error_log "Symbolic link not allowed or link target not accessible: /var/www/html/Menloe" while in /var/log/httpd/access_log I see "GET /Menloe HTTP/1.1" 403 208 In /etc/httpd/conf.d/userdir.conf I have UserDir public_html and <Directory "/home/*/public_html"> AllowOverride All Require all granted Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec Require method GET POST OPTIONS </Directory> The directory ~/public_html/Menloe/ is owned by me, and has permissions drwxr-xr-x. I wonder if anyone has met this problem? Or if anyone is using the apache userdir facility in CentOS 7? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Is this a bug in CentOS-7 BackupPC?
by Timothy Murphy 27 Sep '15

27 Sep '15

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 -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

It is the same problem reported here: https://bugs.centos.org/view.php?id=4192 and solution was to release a new kernel under cplus kernel repo ... Is the same solution for CentOS7? Will be patched? Thanks.

Samba Enterprise from Sernet no longer free
by Robert Moskowitz 26 Sep '15

26 Sep '15

http://www.samba.plus/ Currently this, other than rolling your own, this appears the only way to have a Samba AD on Centos. Later in the Samba 4.3 effort, MIT Kerberos is suppose to be supported so it MAY be easier to roll your own in a while, but until then, things are as they are. I am rethinking my efforts to develop a ARM based AD. I may just fall back (as everyone else) to just an NT style PDC.
