I wish we had one, but we don't and I am the one being asked to fix things. Seriously, get a really good book on doing sysadmin work. 10 years ago, I was recommending O'Reilly's one, "Essential Systems Administration", by Aeleen Frisch. It saved my butt, I assure you, 21 years ago, when I had the same thing happen. > >> Each partition is formatted as a specific type >> of filesystem. The standard Linux filesystems for Upsteam-descended have been ext3, then ext4, and now xfs.

(The system is in Japan and I traveled from NY to Japan, where I am now, just to fix this issue.) Oh, geez, they want you to fix this... but you can't ssh in? This is *so* stupid. Here, fix this, and before you start, let me put an eyepatch over one eye, ties one hand behind your back, and prevent you from using manpages.... Best of luck, guy. mark

photos on iPhone 6
by J Martin Rushton 21 Oct '16

21 Oct '16

A bit of a perennial I'm afraid. My wife has filled up her iPhone 6 with photos, and wants them moved onto my computer. I'm running CentOS 7 patched about 30 minutes ago. Needless to say the computer can't see the data on the iPhone, though it does recognise the phone as an iPhone. Any suggestions (well any that don't involve a steam roller, sledge hammer or GBH to the whole of Apple Inc)? $ uname -a Linux tamar.home 3.10.0-327.36.1.el7.x86_64 #1 SMP Sun Sep 18 13:04:29 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux Thanks, Martin

VM disk question
by Jerry Geis 21 Oct '16

21 Oct '16

I have VMPlayer 12 running a CentOS 7 disk. Works fine. However I wish to change the disk from UUID booting (fstab) to the old style LABEL. (so I can export it and use on another machine). fdisk -l /dev/sda Disk /dev/sda: 21.5 GB, 21474836480 bytes, 41943040 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x0001c6d3 Device Boot Start End Blocks Id System /dev/sda1 * 2048 20482047 10240000 83 Linux /dev/sda2 20482048 22530047 1024000 82 Linux swap / Solaris /dev/sda3 22530048 41943039 9706496 83 Linux however when I run: e2label /dev/sda1 / e2label: Bad magic number in super-block while trying to open /dev/sda1 Couldn't find valid filesystem superblock. Three questions: 1) Am I doing something wrong? 2) Is there a better way? 3) How do I support VM formats (VBox, VHD and VMWare) easily? Thanks, Jerry

xdgurl
by Mark LaPierre 21 Oct '16

21 Oct '16

Has anyone figured out how to make Firefox 45.4.0 on CentOS 6 use xdgurl to handle xdg:// URLs? Google is full of suggestions that don't work. When I select a an xdg:// link I don't get a dialog asking me what to do like Google says I will. Instead I get a message that says Firefox doesn't have a clue how to handle this URL. Do you want to try again? I tried about:config I added: network.protocol-handler.external.xdg user set string /usr/bin/zdgurl Still no joy. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

SSH Weak Ciphers
by Clint Dilks 20 Oct '16

20 Oct '16

Hi, In a recent security review some systems I manage were flagged due to supporting "weak" ciphers, specifically the ones listed below. So first question is are people generally modifying the list of ciphers supported by the ssh client and sshd? On CentOS 6 currently it looks like if I remove all the ciphers they are concerned about then I am left with Ciphers aes128-ctr,aes192-ctr,aes256-ctr for both /etc/ssh/sshd_config and /etc/ssh/ssh_config. Is just using these three ciphers like to cause me any problems? Could having so few ciphers be creating a security concern itself? Thanks The following weak client-to-server encryption algorithms are supported by the remote service: rijndael-cbc(a)lysator.liu.se arcfour256 arcfour128 aes256-cbc 3des-cbc aes192-cbc blowfish-cbc cast128-cbc arcfour aes128-cbc The following weak server-to-client encryption algorithms are supported by the remote service: rijndael-cbc(a)lysator.liu.se arcfour256 arcfour128 aes256-cbc 3des-cbc aes192-cbc blowfish-cbc cast128-cbc arcfour aes128-cbc

Bacula Restore
by Alessandro Baggi 20 Oct '16

20 Oct '16

Hi list, another question about bacula, but this time about restoring backups. I've a server that I must backup every day. My plan is: from mon to sat incrimental backup and on sunday full backup. When I will perform a restore I must restore from last valid full backup and then all valid incremental backup from last backup to specific date. This server has aweb managed application where user can update data or delete data. Suppose that after a full backup, on monday the user upload a file and incrimental backup is performed. On tuesday the user remove the uploaded file and backup is performed. Suppose that I want perform a restore of these jobs. I restore full, mon-incr and I found on restore path file uploaded on monday. When restoring tuesday incr (where the uploaded file was not present), on restore path I will found the uploaded file or bacula remove it with tuesday incremental backup restore? Sorry but today I can't try this due to time issue. Thanks in advance.

port running but connection refused
by Jerry Geis 19 Oct '16

19 Oct '16

Hi All, I have a process running on port 5070... I'm using CentOS 7. iptables is running firewalld should be stopped and disabled. When I telnet localhost 5070 I get connection refused. When I stop iptables I still get connection refused. netstat -tnlv | grep 5070 tcp 0 0 192.168.1.8:5070 0.0.0.0:* LISTEN so the process is running and listening. ps ax | grep firewalld returns nothing except the grep command. What else could be blocking this connection? Thanks, Jerry

Dear Centos Users We are running centos on our HPC. Indeed, we have a problem with running some software using X11 server such as pymol. For your information, we are using cygwin to access to the hpc (using ssh -X -Y username(a)xxx.xxx.xxx.xxx) When we are testing glxinfo on my desktop, it gives us the following error: [username@hpc ~]# glxinfo name of display: localhost:10.0 X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 149 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 20 Current serial number in output stream: 23 The weird thing is that when we use another desktop computer running the same cygwin version and accessing with the same username, glxinfo works fine. Indeed, echo $DISPLAY on my desktop computer gives us localhost:10.0 , while it gives localhost:13.0 on the another desktop. If I set DISPLAY on my desktop to localhost:13.0, it doesn't work One more point, if we run glxinfo on the another desktop using my account and logging at the same time from my desktop with the same username and setting DISPLAY to 13:0, glxinfo works on my desktop. Any kind of help will be highly appreciated. Sincerely; M. Ibrahim

Hi I have a disk which two of the partitions are part of a RAID1 setup. I'm trying to rename the the second raided partition mdadm -E /dev/sdc4 /dev/sdc4: Magic : a92b4efc Version : 1.2 Feature Map : 0x1 Array UUID : 83d7657b:ebfddcb7:36b0fa14:d29a350c Name : oldname:2 Creation Time : Tue Aug 30 15:25:10 2016 Raid Level : raid1 Raid Devices : 2 Avail Dev Size : 486696960 (232.08 GiB 249.19 GB) Array Size : 243348480 (232.08 GiB 249.19 GB) Data Offset : 262144 sectors Super Offset : 8 sectors Unused Space : before=262056 sectors, after=0 sectors State : clean Device UUID : 97aba979:dd4cf85c:f6dbf4f6:f1e9ccab Internal Bitmap : 8 sectors from superblock Update Time : Fri Sep 23 14:21:00 2016 Bad Block Log : 512 entries available at offset 72 sectors Checksum : 749e26a8 - correct Events : 7319 Device Role : Active device 0 Array State : A. ('A' == active, '.' == missing, 'R' == replacing) For the first partition I stopped the RAID using mdadm --stop /dev/md127 and then reassembeld using mdadm --assemble /dev/md127 --name=newname_boot --update=name /dev/sdc2 The first partition was easy as the system had started the RAID, but the second parition the system does start, and when I try to assemble it, it tells me it's already active:- mdadm --assemble --uuid=83d7657b:ebfddcb7:36b0fa14:d29a350c --name=newname2 --update=name /dev/md2 /dev/sdc4 mdadm: Found some drive for an array that is already active: /dev/md/oldname:2 So any ideas on how i can rename this ? Thanks Phil.
