(OT) Computer seems to have died
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

kernel memory accounting
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

getting X started...
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

ssh & ksh question
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

kernel memory accounting
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.

tool for a comprehensive list of the storage structure
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/vg_internal_e-lv_internal_srv: UUID="f85b7a2c-..." TYPE="crypto_LUKS"

IP aliases for services (including dhcpd)?
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

Setting up PXE server
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

daemon for nfs client
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.

I previously posted about a really weird root filesystem. It started on

Somewhere tucked in the back of my mind a memory is screaming no.

CentOS 7 httpd cgi script file not able to write to /tmp
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.
Thanks,

Up to date guide/information Sendmail SMTP Auth
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

meminfo
Dear All
As far as I know , to check for the amount of installed RAM on my
centos server I checked it as:
#more /proc/meminfo
Can you please let me know how can I check for the instantaneous
occupied amount of my RAM the similar way the task manager shows it on
my Win server ?
Thank you in advance

I have had this in the past where either the CPU or PSU fan had died.

Rsync and differential Backups

a incremental backup copies everything since the last incremental
a differential copies everything since the last full.
rsync is NOT a backup system, its just a incremental file copy
with the full/incremental/differential approach, a restore to a given
date would need to restore the last
