A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).

i'll need a Shell script that scans thru creation dates of all patches (ideally only the security ones but
if this is not possible, then all patches) installed in an RHEL 7 server, get the latest one, compute
the difference from today's date & give the difference in number of days & if the difference is
more than 90 days, echo out a message, "It has been more than 90 days since last patch)

Purpose is to check the last patch date & remind Linux admins.  Believe RHEL releases patches
at least every 3 monthly?

i am in particular folder say abc.

I did ls -ltr where there are bunch of files.

i want to search all the files starting with file name xyz alone ignoring other starting with pqr etc(ignore pqr000.log.20170806.gz etc).
My search should result like

xyz123.log.20170806.gz
xyz456.log.20170806.gz
xyz789.log.20170806.gz etc



What is the command i have to use for that.

is it grep or find or something else.

when i gave grep xyz.* it did not gave any result.

how searching inside a file content is different from search outside on unix file names.

any good link on these commands? please advise

I have inherited a legacy Fedora server running v17, I need to migrate the server to a Hyper-V host and I would like to update the OS as well.

When I try to upgrade to v18 using fedup-cli --network 18 I get the following error

Downloading Failed: couldn't get boot images: curl#22 - "The requested URL returned error: 404 Not Found"

The server has network access as I have manually downloaded Webmin onto it, I can access BBC etc. There is no proxy configured

I have followed a tutorial to update the Repos

**************************************************************************************************
In your /etc/yum.repos.d/ directory are a number of configuration files specific to yum and repositories.


In the case of Fedora Linux, you’ll want to change each of these so they reflect the new archive site, vs. the original download site, which no longer resolves and does not exist.

The original URL looks like this:

baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/$releasever/$basearch/os/


baseurl=http://archive.fedoraproject.org/pub/archive/fedora/linux/core/$releasever/$basearch/os/

This still hasn't resolved the issue

I have a Linux bind server hosting a

the rzone  file in /var/named/data/51-168-192.zone

the SOA line says this is    "IN SOA  netsvc.int.alconi.com.   root.netsvc.int.alconi.com. 203 3h 1h 1w 5m

I want to create a windows DNS in the another namespace that would be       "win2016.int.alconi.com" or maybe "win.alconi.com"  with its own DNS servers, can I do this ?

should I create another subnet for the win.alconi.com?

if so how ,

I am very ignorant on this , and really really could use some help

Hello

I have tried a number of times to reduce the size of my EBS volume. I keep running into problems.

I am using Centos 7.3.1611 and Plesk (set up through Amazon marketplace)

I have managed to copy all the files over from the old server to the new using the instructions here (https://superuser.com/questions/1123799/how-to-decrease-size-the-ebs-root-volume-of-the-rhel-instance-in-aws) - as well as similar other guides.

The only difference is because I am using xfs instead of ext4 I was unable to do the e2label

When I attach the new volume to the instance as /dev/sda1 it does not load. I cannot connect to it using SSH and websites do not load.

I am at a loss now. I have tried so many times. I made a mistake making my initial EBS volume size way too big and it is costing me quite a bit of money every day.

I am unsure if the problem is because I am formatting my drive is XFS. This was the format of the original drive when I first set up the instance. I have not been able to find a guide that details how to shrink an EBS volume that is formatted in XFS, they are all for ext4.


If any one could provide some assistance that would be much appreciated.
