How does one put centos on a laptop? My understanding that laptops no longer come with optical drives. Booting from an install disk would be difficult. >From https://wiki.centos.org/HowTos/Laptops : Preparation tasks Repartition your harddisk Backup your Master Boot Record (MBR) Modifying your bootloader My understanding is that most laptops have at most one harddisk.

Hi Users I am using RHEL 6.5 on my server. From top command i can see that the processors in my server are spending a lot of time on wait for I/O. I can see high percentage in terms of 30-50% on "wa" time. Here is the df output about the disk space in my system: ********** [root at localhost images]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1

Hello, I have an old IBM Netvista. Lately, it would seem to go into sleep mode but I have all that disabled. I would have to power off to wake it up. Now I think its done. I can't even get to the CMOS/BIOS. The power light is on but no beeps or anything spinning up. I have two of these Netvistas and had put on away when I upgraded one of the machines. I pulled the HD from it and installed

Hi CentOS experts, I am using CentOS 7. Trying to disable kernel memory accounting: according to https://www.kernel.org/doc/Documentation/cgroup-v1/memory.txt, passing cgroup.memory=nokmem to the kernel at boot time, should be able to archive that. However it is not the case in my exercise. These are what I have now $ grep CONFIG_MEMCG_KMEM /boot/config-3.10.0-327.36.3.el7.x86_64

I've got a new VM installed for me by a sysadmin who apparently did a minmal install. As a result I've installed a bunch of things to try to get X going, including yum groupinstall "development and creative workstation", "Desktop platform" "mate desktop" but so far I've not found the incantation to get it to start up X at boot time. As far as I can

I need to run a report, source file on system 1, on system 2. I'd like to do this in one script, not have a second script to run it. Now cat script | ssh system2 works fine. But no matter what I've tried, it gags on ssh system2 <<EOF blah, blah EOF. Mostly, I have a multiline awk script in the script, with \ at the end of each line... *but* I think it's seeing "\n" as

I have 3.10 kernel. I am running some data processing job, need to first copy big (>5 GB) input files. The jobs were killed, because the system thought I used 5 GB memory from the file copying.

In days of old, in Solaris there was a daemon for NFS Client, and NFS server (actually several including portmap...). I am unable to find reference to the daemon that runs NFS client But the RedHat Documentation does not explain the NFS client daemon. Is this a service or something else. on centos6.5 I previously posted about a really weird root filesystem. It started on another non critical

Hi folks, I inherited a very old computer (I guess about 8 years old) which I'd like to use for some training on CentOS. I downloaded images for CentOS 6.4 i386 (DVD 1 and 2) and burned them onto discs. After inserting DVD 1 into drive and booting, on the "Welcome to CentOS 6.4!" screen I select "Install or upgrade an existing system". I then skip the media test and

I'd like to consolidate the services from several old servers onto 2 CentOS7 VMs that are currently running dhcpd in a balanced/failover configuration. It will simplify things to add the IPs from the old servers as aliases, at least temporarily so everything will continue to connect without changes. However, after adding the first one, I see in the logs that DHCPD is sending its DHCPACKs

Hello all, I've been googling my brains out since yesterday looking for up-to-date information on this matter, and have found information that is anywhere from 15 to 5 years old. I'd really like some information that much more up to date on the subject. Specifically configuring Sendmail SMTP authentication (_no smart host stuff_). I've got Sendmail 8.14 installed on a CentOS 7.3

I would like to have a smart cli tool, that shows a comprehensive list about the local storage structure: An output like: /srv /dev/mapper/luks-f85b7a2c-...: UUID="ca924fad-..." TYPE="ext4" /dev/mapper/vg_internal_e-lv_internal_srv: UUID="f85b7a2c-..." TYPE="crypto_LUKS" vg_internal_e /dev/md3: UUID="1Fi2Ex-..."

As a matter of interest, why does systemd start sessions every couple of minutes? And if it is completely standard, is it necessary to inform me of this in /var/log/messages? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Fun fact... If I echo my data to the same directory as the script is located in it works. But it does not allow writing to /tmp I'm good with that.

I've looked around in the menus and googled this, but I can't find a way to make the login require a username instead of just showing the available users to select from. ?Where do I change this? ?I'm using CentOS 6.5. Thanks, -wes

Folks On a lark, I am trying to set up a PXE server so I can use network boots to load new computers {some of which are virtual) at home. It's more of an intellectual exercise than a work necessity. I've read several "how to" documents, and even the one on the RedHat site doesn't help. (For example, it refers to /etc/xinet.d instead of /etc/xinetd.d, and the careless

Will anything break if you never log into the console after the initial reboot? I just installed my first copy in a VM, and connected over ssh as I normally would for all access after the install. But I just happened to leave the console window open and later noticed that it was prompting for license acceptance which I didn't see in the ssh login. On a more typical install, no one will
