Hi, all. I was getting: `http://mirror01.th.ifl.net/epel/6/x86_64/repodata/c60f7c3ee6f9a4902d5ce9dd181a84ca684bba1a1df1c612702c7c6760a04645-filelists.sqlite.bz2: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirror01.th.ifl.net'" Trying other mirror. ftp://ftp.mirrorservice.org/sites/dl.fedoraproject.org/pub/epel/6/x86_64/re…: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'ftp.mirrorservice.org'" Trying other mirror. ftp://ftp.fedora.is/pub/epel/6/x86_64/repodata/c60f7c3ee6f9a4902d5ce9dd181a84ca684bba1a1df1c612702c7c6760a04645-filelists.sqlite.bz2: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'ftp.fedora.is'" Trying other mirror. ftp://ftp.funet.fi/pub/mirrors/fedora.redhat.com/pub/epel/6/x86_64/repodata…: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'ftp.funet.fi'" Trying other mirror. ftp://mirrors.fedoraproject.org.uk/dl.fedoraproject.org/pub/epel/6/x86_64/r…: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.fedoraproject.org.uk'" Trying other mirror.

You could try using --skip-broken to work around the problem` every time I ran `sudo yum update'. This happened on Fedora 17 also. I've had to switch both machines to Ubuntu because I need working machines. I've Googled this extensively & changed my nameservers, commented out relevant lines in the configs, etc, etc but no luck so far. Ubuntu works fine & I have no network problems (two HP ProCurves 2124s working normally over the rest of the network: 17 machines). Is there a workaround for this as I need a working CentOS box. Any help appreciated.

5.9, GNOKII, SMS and Huawei [ E160G | E176 ]
by Jobst Schmalenbach 14 Aug '13

14 Aug '13

Hi I want to setup a SMS system for Nagios on a 5.9 box. I read in a blog that the two modems Huawei [ E160G | E176 ] work with 6.3. Anybody any experience with those modems and do they work with 5.9? Are there any other devices that are better/recommended? Thanks Jobst -- 186,262 miles/second : Not just a good idea, it's the LAW. | |0| | Jobst Schmalenbach, jobst(a)barrett.com.au, General Manager | | |0| Barrett Consulting Group P/L & The Meditation Room P/L |0|0|0| +61 3 9532 7677, POBox 277, Caulfield South, 3162, Australia

3TB External USB Drive isn't recognized
by james 13 Aug '13

13 Aug '13

We have a 3TB external USB drive that I am trying to attach to some CentOS5 servers. I have tried an older Dell PE1950 and a newer R310 but neither one seems to be able to read the drive. It works no problem on windows servers/workstations and I was able to format with NTFS. I know there are different methods for formatting large disks but this one doesn't even seem to show up as a /dev/ device. I supplied the dmesg output I see when I plug in the device. Is this a limitation of CentOS5? Do I need some additional package / driver / update? usb 2-1.2: new high speed USB device using ehci_hcd and address 5 usb 2-1.2: configuration #1 chosen from 1 choice scsi7 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 5 usb-storage: waiting for device to settle before scanning Vendor: ASMT Model: 2105 Rev: 0 Type: Direct-Access ANSI SCSI revision: 06 sde : very big device. try to use READ CAPACITY(16). sde : READ CAPACITY(16) failed. sde : status=0, message=00, host=5, driver=00 sde : use 0xffffffff as device size SCSI device sde: 4294967296 512-byte hdwr sectors (2199023 MB) sde: Write Protect is off sde: Mode Sense: 43 00 00 00 sde: assuming drive cache: write through sde : very big device. try to use READ CAPACITY(16). sde : READ CAPACITY(16) failed. sde : status=0, message=00, host=5, driver=00 sde : use 0xffffffff as device size SCSI device sde: 4294967296 512-byte hdwr sectors (2199023 MB) sde: Write Protect is off sde: Mode Sense: 43 00 00 00 sde: assuming drive cache: write through sde:<6>usb 2-1.2: reset high speed USB device using ehci_hcd and address 5 usb 2-1.2: reset high speed USB device using ehci_hcd and address 5 usb 2-1.2: reset high speed USB device using ehci_hcd and address 5 usb 2-1.2: reset high speed USB device using ehci_hcd and address 5 sd 7:0:0:0: SCSI error: return code = 0x00070000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 sd 7:0:0:0: SCSI error: return code = 0x00070000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 usb 2-1.2: USB disconnect, address 5 sd 7:0:0:0: SCSI error: return code = 0x00070000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 sd 7:0:0:0: SCSI error: return code = 0x00010000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 sd 7:0:0:0: SCSI error: return code = 0x00010000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 sd 7:0:0:0: SCSI error: return code = 0x00010000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 sd 7:0:0:0: SCSI error: return code = 0x00010000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 Dev sde: unable to read RDB block 0 sd 7:0:0:0: SCSI error: return code = 0x00010000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 sd 7:0:0:0: SCSI error: return code = 0x00010000 end_request: I/O error, dev sde, sector 0 Buffer I/O error on device sde, logical block 0 unable to read partition table sd 7:0:0:0: Attached scsi disk sde sd 7:0:0:0: Attached scsi generic sg7 type 0 usb-storage: device scan complete usb 2-1.2: new high speed USB device using ehci_hcd and address 6 usb 2-1.2: configuration #1 chosen from 1 choice scsi8 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 6 usb-storage: waiting for device to settle before scanning Vendor: ASMT Model: 2105 Rev: 0 Type: Direct-Access ANSI SCSI revision: 06 sde : very big device. try to use READ CAPACITY(16). sde : READ CAPACITY(16) failed. sde : status=0, message=00, host=5, driver=00 sde : use 0xffffffff as device size SCSI device sde: 4294967296 512-byte hdwr sectors (2199023 MB) sde: Write Protect is off sde: Mode Sense: 43 00 00 00 sde: assuming drive cache: write through sde : very big device. try to use READ CAPACITY(16). sde : READ CAPACITY(16) failed. sde : status=0, message=00, host=5, driver=00 sde : use 0xffffffff as device size SCSI device sde: 4294967296 512-byte hdwr sectors (2199023 MB) sde: Write Protect is off sde: Mode Sense: 43 00 00 00 sde: assuming drive cache: write through sde:<6>usb 2-1.2: reset high speed USB device using ehci_hcd and address 6 usb 2-1.2: reset high speed USB device using ehci_hcd and address 6 usb 2-1.2: reset high speed USB device using ehci_hcd and address 6 usb 2-1.2: reset high speed USB device using ehci_hcd and address 6 usb 2-1.2: reset high speed USB device using ehci_hcd and address 6 INFO: task usb-stor-scan:26787 blocked for more than 120 seconds.

Macromedia Flash data (compressed), version 9
by Michael Hennebry 13 Aug '13

13 Aug '13

I've copied some files from the firefox cache. According to file, they are Macromedia Flash data (compressed), version 9. How do I play them locally? I saw them from a remote site through firefox, but I cannot seem to play them locally. neither mplayer nor vlc seems to work. Pointing firefox at them didn't work either. Any ideas? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "On Monday, I'm gonna have to tell my kindergarten class, whom I teach not to run with scissors, that my fiance ran me through with a broadsword." -- Lily

Hey Y'all, I'm trying to turn off the kernel screen blanker that shuts off the video after about 10 minutes of inactivity at the keyboard. After extensive googling I've found two ways to *NOT* do it. In my home .xinitrc setterm -blank 0 -powersave off -powerdown 0 xset s off In /etc/rc.local /usr/bin/setterm -powersave off -blank 0 I've tried both to no effect. Of course I've turned off the screen saver in the Gnome desktop. How do I stop this machine from blanking the screen with no activity? I want video full time! I know someone is going to ask, "Why do you want to do that?", so to save you from asking. 1. I'm setting up a kiosk that customers can use interactively. It's not very inviting to passers by when the screen is blank. 2. I want to watch movies and Skype without having to poke the mouse all the time. 3. My monitor is very unhappy when the video signal is cut off. 4. My wife is very unhappy when the screen goes blank. 5. Insert your reason here. I just want it to stop. ;-) -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Motherboard and chipset compatibility
by Glenn Eychaner 13 Aug '13

So, having returned from a month's vacation, I'm back to work on attempting to build a set of small form factor CentOS compatible computers. I've really tried to do my homework, but this doesn't appear (at first glance) to be at all easy. It's not made easier by the fact that I have to get it right the first time (and I haven't built a PC in a decade); the time and money cost of shipping anything to and from my remote location in Chile means I can't afford to waste time buying and returning things. First question: does anyone have any experience with the Jetway NF9E-Q77 or ZOTAC Z77ITX-A-E motherboards? Having struck out on Intel Q77 or Z77-based SFF motherboards (the DQ77** series is completely out of stock everywhere, and the DZ77** series is ATX only), I have found a couple of Mini-ITX systems based on these two motherboards. Second question: Where can I get information about which Intel chipsets (Z77 vs Z87 vs Q77 vs C602 vs ...geez, there are a LOT of chipsets, as evidenced by http://www.supermicro.com/support/faqs/os.cfm) are supported by CentOS 6 / RHEL 6? I have not been able to find this information on either the Intel, RedHat, or CentOS web sites. Third (more general) question: My requirements are (I believe) modest: * 1U short-depth rackmount chassis OR Mini-ITX small-footprint chassis * Dual GbE network ports * Dual 1920x1200 monitor display * One SSD drive * 32-bit CentOS 6.4 compatible. It's the combination of the first, third, and fifth requirements that really seems to get me hung up. I've found plenty of 1U server systems (such as SuperMicro), but none of them support dual displays. (Some of them have a PCIe16x riser card that could conceivably accomodate a separate graphics card, assuming I could find one that fits; I have Emails in to various tech supports to inquire about this. I've found LOTS of 2U solutions, thanks, but only have 1U of available rack.) As far as Linux support goes, the RHEL Hardware List has thus far been pretty useless (much of the hardware on it is obsolete or discontinued), and most manufacturers' web sites have been equally useless. (One exception being ASUS, which has a Linux-compatibility list at http://www.asus.com/websites/global/aboutasus/OS/Linux.pdf SuperMicro has a very nice list referenced above, but none of their small form factor motherboards support dual displays AFAICT; I have found nothing useful at Intel's site.) Does anyone have any resources they'd like to point me to? Thanks, -G. -- Glenn Eychaner (geychaner(a)lco.cl) Telescope Systems Programmer, Las Campanas Observatory

Again, how does one find this kind of thing out? There has to be a better solution than 3 days of web searches, Emails to tech support, and forum posts. In addition, the USFF Optiplex seems to be limited to a Core i3 processor and a mere 2GB of memory, which while acceptable is not optimal (and worse than some other solutions I'm looking at). And for everyone suggesting KVMs, VMs, SSH, or other solutions...this is a telescope operations system, so none of those are really appropriate to the task, I'm afraid. I really want direct monitor/keyboard/mouse connections (and yes, I keep a hotspare warmed up at all times in case of a critical failure, and have had to use it on more than one occasion). And I'm sorry my postings don't seem to thread right in the archives. I subscribe to the Digest form orf the list and am compiling these replies using the web archives. Anyway, -G. -- Glenn Eychaner (geychaner(a)lco.cl) Telescope Systems Programmer, Las Campanas Observatory
