how2 mount ntfs partition that is part of a full HD image file
by Fred Smith 05 Oct '14

05 Oct '14

I have a full disk image file (courtesy of ddrescue), and need to mount one of its partitions. I suppose I should have just extracted the single partition when I was using ddrescue, but right now I have the whole disk instead, and no disk space left to re-do the extraction (in fact I won't be able to use the system where I did it for several weeks, so I'd love to be able to mount just the partition from the image I have). I'll be doing some digging, but thought I'd inquire here too. thanks in advance! -- ------------------------------------------------------------------------------- Under no circumstances will I ever purchase anything offered to me as the result of an unsolicited e-mail message.

Mounting LUNs from a SAN array - LUN mappings to devices in /dev/ - are they static?
by Rafał Radecki 04 Oct '14

04 Oct '14

Hi All :) I am currently involved in a project in which there is a SAN array (Sun Storagetek 2540) which exports LUNs for some servers with Centos 5.2 x86. I will be performing a migration to Centos 5.9 x86_64 in some time and am gathering needed info now :) I am trying to find the place in the OS where there is the information about LUN mappings to /dev/ devices. For example on array level I have an exported LUN with number 8. I see it on one of the servers with lsscsi as: # lsscsi | grep '7\:0\:0\:8' [7:0:0:8] disk SUN LCSM100_F 0735 /dev/sdj As I said I need to perform migration of the OS to Centos 5.9 x86_64 and am curious where from does the mapping scsi device 7:0:0:8 <-> /dev/sdj come? I have some complex logical volume (Veritas Volume Manager) setup based on /dev/ disks (which are derived from LUNs imported from the array) and will need to recreate it on destination servers. My coworker said that udev may be assigning the /dev/sdj (and other) identifier so I checked this. In /etc/udev/rules.d/* I see rules for scsi subsystem (sysfs type 0 is "disk"): ACTION=="add", SUBSYSTEM=="scsi", WAIT_FOR_SYSFS="ioerr_cnt" ACTION=="add", SUBSYSTEM=="scsi_device", SYSFS{type}=="0", RUN+="socket:/org/kernel/diskres/uevents" ACTION=="remove", SUBSYSTEM=="scsi_device", RUN+="socket:/org/kernel/diskres/uevents" So I do not see anything which could answer my question. There have been other rules for different sysfs types but I think they are not relevant in my case. In sysfs in /sys/bus/scsi/devices/7:0:0:8 I found: # ll block\:sdj lrwxrwxrwx 1 root root 0 Oct 4 17:57 block:sdj -> ../../../../../../../../../../block/sdj Where else can I look for the LUN<->/dev/ device mapping rules? How are the LUNs mapped to operating system devices? Is there a way to add a static mapping so that also on a new server after attaching SAN array LUN number 8 will be visible as /dev/sdj? I think that there is a possibility that on a new server mentioned LUN will be visible as a different /dev/sd? :( That could potentially break my logical volume setup on the destination server. Any info will be greatly appreciated :) BR, Rafal.

en01 network
by Jerry Geis 04 Oct '14

04 Oct '14

I have installed CentOS 7. I added "biosdevname=0 net.ifnames=0" at install time. I still have a network name of en01 and not eth0. How do I get eth0 when viewing ifconfig? dmesg | grep eth0 show its being detected, and being renamed. systemd-udev renaming eth0 to en01... I then looked in /etc/udev and dont see anything of value... Thanks, Jerry

CUPS Enable printer from command line
by Rodrigo Pichiñual Norin 04 Oct '14

04 Oct '14

Hi all: I am investigating about Common Unix Printing System (CUPS).but, I have one doubt, when I execute the command "lpc status" , the output it's : for example: Printer-one: printer is on device 'lpd' speed -1 queuing is enabled printing is disabled 10 entries daemon present so the status the printer it's "DISABLED", I changed in the file /etc/cups/printers.conf the param "State stopped" by "State Idle" and then it's worked. My question it's, exist any command for enable printer in status disabled without modify the file printers.conf???? pd: excuse me my inglish (I speak spanish) Thanks -- *Atte.

ShellShock and bash status

03 Oct '14

For those of us still in shell shock, the following was sent several days ago under a misleading subject/thread mixed in with a bunch of other nonsense. (Message-ID: <54291071.7010209(a)centos.org>) According to Johnny the second bash patch addressed all of the known issues. I had been waiting for a third patch to come through and missed this important information sent on Monday.

Anyone have LibreSSL working on CentOS 6.5?
by Alan McKay 03 Oct '14

03 Oct '14

Hi folks, I searched the list for LibreSSL and found only one mention of it! Has anyone gotten this working? I have it compiling no problem, but removing OpenSSL is another story of course. It seems to be compiled with FIPS support and of course there is no such thing in LibreSSL - that is something they tore out thanks, -Alan -- "Don't eat anything you've ever seen advertised on TV" - Michael Pollan, author of "In Defense of Food"
