I set up an Amazon Linux 2023 EC2 and migrated the disk over to a new one to use LVM, (I didnt put the BIOS and /boot/efi on LVM.) I believe my system is using EFI, as indicated by the contents in /sys/firmware/efi/, but I'm facing an error with grub2-install. Here's the sequence of commands I ran:

grub2-mkconfig -o /boot/grub2/grub.cfg
dracut -f -H --regenerate-all
grub2-install --recheck /dev/nvme1n1p2

However grub2-install fails with the following error:

Generating grub configuration file ...
done
grub2-install: error: /usr/lib/grub/x86_64-efi/modinfo.sh doesn't exist. Please specify --target or --directory.

I want to copy the whole log that are stored in the AWS S3 bucket if the following line is present:

\"Key\" : 951332,\n

I've tried escaping by trying this:

aws s3 ls s3://bucket_name | grep "/\"Key/\" : 951332,/\n" --recursive

but not getting anything back, does anyone know how I can run the grep in this manner?

Fresh Webmin install on Ubuntu 20.04 on Amazon Lightsail * I added the line to iptables as per their instructions:

sudo iptables -A INPUT -p tcp -m tcp --dport 10000 -j ACCEPT

* I have added port 10000/tcp to ufw also. * When I go to the browser https://myip:10000 the browser stays loading for a while then says:

cant open the page because the server where this page is located isn't responding

What am I missing? **Edit:** When I run sudo service webmin status I get this:

I am suddenly seeing the following warning when I ssh to my server. I researched it and cannot seem to find the cause neither I am able to get rid of it. Please, can someone help? Thank you!

As I'll need to install the layrst version of Python, will need to install a particular repository - Inline with Upstream Stable (IUS) - that provides rpm packages for new versions of selected software. If I was using CentOS 7, would run yum -y install https://centos7.iuscommunity.org/ius-release.rpm and then for installing Python would do something like yum -y install python36u If I try to run the initial command, then I get in the first command > Loaded plugins: extras_suggestions, langpacks, priorities, update-motd > > Cannot open: https://centos7.iuscommunity.org/ius-release.rpm . Skipping. > > Error: Nothing to do and in the second > Loaded plugins: extras_suggestions, langpacks, priorities, update-motd amzn2-core | 3.7 kB 00:00:00 > > No package python36u available. > Error: Nothing to do All in all, ---------- Considering I'm now using Amazon Linux 2, NAME="Amazon Linux" VERSION="2" ID="amzn" ID_LIKE="centos rhel fedora" VERSION_ID="2" PRETTY_NAME="Amazon Linux 2" ANSI_COLOR="0;33" CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2" HOME_URL="https://amazonlinux.com/ " what would be the equivalent commands for Amazon Linux 2?

On an EC2 instance, I am attempting to install a Python package using pip, but receive an exception that states

: No module named 'setuptools'

. For context, the command I run is

pip install --user mlflow

I attempt to resolve the issue my installing setuptools with the following command:

yum install python36-setuptools

. Yet, the message returned indicates that setuptools is already installed:

Package python36-setuptools-36.2.7-1.33.amzn1.noarch already installed and latest version
Nothing to do

Please advise. **UPDATE**: After switching the EC2 instance from Amazon Linux AMI 2018.03.0 to Amazon Linux 2 AMI I was able to successfully install mlflow using pip. The question still remains - why was I able to successfully install using Amazon Linux 2 AMI but not Amazon Linux AMI 2018.03.0?

Probably no big deal although I have questions. Background: My home wireless was being overrun with all the devices. Have 6 people on the net and each have multiple devices. Then the kids would have friends over and the device count would go up. I have identified the mac addys for the local devices and modified iptables and dhcp to redirect unknown devices to a specific web page and not allow them on the network. So for the problem. During my watching of the network I have found that Amazon, Xbox and some Androids ping multiple different ports on my router. Most ports are above 1024, although I have seen some below that. Pings happen about every minute and a half per device. Some ping 10 times, other less. Every once in awhile we get more than 10 pings; all are using different destination ports. Some pings are from the source out in inet land with most being from the local device. Sure, ping uses a tiny amount of bandwidth. So my question: Anybody have any idea of what are these pings for? Looking at it as a security issue, it sure could be a 'slow' port scan to find holes in my systems. Since these devices are smart devices, just about anything could be done given a flaw in my network if there is one. I have dropped them at the router using the INPUT and FORWARD chains unless somebody gives me a good reason not to. Maybe I am thinking all wrong about this - ideas? Thanks Todh Welp, made an executive decision. Decided to drop all of the above packets and see who here complained. So far nobody! In other words, I gave up and just dropping stuff was easier.

This directory /data/files/ has thousands files like: 1test 2test 3test [...] 60000test 60001test I'm also sending them to a S3 Bucket (AWS), using AWS CLI. However, sometimes the S3 bucket can be offline and because of that the file is skipped. How can I check if the file that exists in /data/files/ is also in the S3 Bucket? and if not copy the missing file to S3? I would prefer to do this using BASH. Also if I need to change the AWS CLI for another one, can be.

I have an ubuntu instance on AWS and I want an email when 80% of disk space is consumed. I have checked the cloud watch but there is no such option to monitor disk space. There is only one option which is custom metric https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/mon-scripts.html but I am not sure that it will give an email alert. Please guide me for the same.

I have like 15 VPS CentOS machines with SSH access on one hosting and I need to move them all to Amazon Web Services to EC2 That hosting is not supporting anything expect of SSH Which the easiest options do I have to move them to AWS?

We have an Amazon Linux server and we scan it using OpenVAS. It detected one high vulnerability which is **Amazon Linux Local Check: alas-2016-754**. Looking at the solution it says **Run yum update php70 to update your system.** The vulnerable package detected is: Vulnerable package: gmp Installed version: gmp-6.0.0-11.16.amzn1 Fixed version: gmp-7.0.11-1.16.amzn1 At first we don't have php installed. So what we did is install latest version of php. Upon running the suggested solution the result is "No packages marked for update". We also did yum update. After doing another scan the package is still detected by OpenVAS. The question is how to update this package?

Recently I have installed a PHP on Amazon Linux to run Chevereto. It's an image hosting service. When I wanted to install it on my EC2 instance, I got the following error: > Aw, Snap! Your web server lacks some requirements that must be fixed to install Chevereto. Please check: **Enable ZipArchive PHP class** Does anyone know how to enable this on Amazon Linux?

I’m using Amazon Linux and running a script through a Jenkins job, including this line touch /usr/java/jboss/standalone/deployments/myproject.war.dodeploy which results in the error … touch: cannot touch ‘/usr/java/jboss/standalone/deployments/myproject.war.dodeploy’: Permission denied I thought I had the perms and groups set properly, so I output those in my script as well. But I can’t see why things are falling apart. Below is the output.

I don't want to allow others read access, so I have added my user and the apache user to a group called apachme and then set that group to all the files and folders I want apache to have access to, including the root of the webpage. I have then given group and owner all permissions. After this apache still can't access the files without setting the read permission to allow all(rwxrwxr--(0774)). The folder that contains the index file, it's owned by apache with the group apachme and the permissions rwxrwxr-x(0775) with this I get a 500 error, changing it to 0774 will let it run fine These where just to confirm what user apache was running under and that it had been added to the group.

How can I check if Apache is installed in my Amazon Linux AMI, which is based on RHEL 6? In Ubuntu, I use: dpkg --get-selections | grep apache But that doesn't work in this case. Note, I need to be able to tell if Apache is installed even if it isn't a service.

I did login into amazon server on terminal by ssh -i /path/to/pem_file.pem ec2-user@ec2-host.amazonaws.com. It was working fine but there are too many log files into ec2/ folder so i tried to delete them by using the command (find . -file_name_to_delete_all_series"*" -delete) and suddenly i noticed all files deleted and now i am not able to connect to server by using above ssh login command and getting this error "Permission denied (publickey)". when i am hitting it with -v then its showing $ ssh -i /path/pem.pem ec2-user@ec2-host-1.amazonaws.com -v OpenSSH_6.7p1 Ubuntu-5ubuntu1.4, OpenSSL 1.0.1f 6 Jan 2014 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to ec2-my_server port 22. debug1: Connection established. debug1: key_load_public: No such file or directory debug1: identity file /pem_file.pem type -1 debug1: key_load_public: No such file or directory debug1: identity file /pem_file.pem-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.7p1 Ubuntu-5ubuntu1.4 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.6.1 debug1: match: OpenSSH_6.6.1 pat OpenSSH_6.6.1* compat 0x04000000 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr umac-64-etm@openssh.com none debug1: kex: client->server aes128-ctr umac-64-etm@openssh.com none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ECDSA 34:77:b9:f0:87:6b:e8:c7:31:90:92:7c:a3:b5:4b:58 debug1: Host 'ec2-server.amazonaws.com' is known and matches the ECDSA host key. debug1: Found key in /home/apps/.ssh/known_hosts:1 debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /pem_file.pem debug1: Authentications that can continue: publickey debug1: No more authentication methods to try.

I'm using Packer to create a VM with CentOS 7, and exporting it as a .ova file at the final of installation. By default, Packer creates a 40GB Virtual Disk (.vmdk). After the installation, if I import the .ova file in VirtualBox (just for tests) and list the file system of the created VM, I got this: [root@localhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/cl-root 37G 1.6G 35G 5% / devtmpfs 1.3G 0 1.3G 0% /dev tmpfs 1.4G 0 1.4G 0% /dev/shm tmpfs 1.4G 8.4M 1.3G 1% /run tmpfs 1.4G 0 1.4G 0% /sys/fs/cgroup /dev/sda1 1014M 166M 849M 17% /boot tmpfs 268M 0 268M 0% /run/user/1000 tmpfs 268M 0 268M 0% /run/user/0 If I import the same .ova file in a Amazon Instance, this time increasing the size of my root storage volume to 100GB, I got this file system: [root@localhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/cl-root 50G 4,0G 46G 9% / devtmpfs 15G 0 15G 0% /dev tmpfs 15G 0 15G 0% /dev/shm tmpfs 15G 18M 15G 1% /run tmpfs 15G 0 15G 0% /sys/fs/cgroup /dev/xvda1 1014M 185M 830M 19% /boot /dev/mapper/cl-home 45G 89M 45G 1% /home tmpfs 3,0G 0 3,0G 0% /run/user/0 tmpfs 3,0G 0 3,0G 0% /run/user/1000 Note that the / was increased to 50GB, and now a new /home was automatically created. This was driving me crazy, until I find the cause: All the instalallation was made automatically by Packer, using a kickstart config file wich uses autopart for partitioning. In RedHat docs, I found this: autopart (optional) Automatically creates partitions: a root (/) partition (1 GB or larger), a swap partition, and an appropriate /boot partition for the architecture. On large enough drives (50 GB and larger), this also creates a /home partition. So, I decided to manually create the partitions, using this lines in the kickstart file instead of autopart: part /boot --fstype ext4 --size=1014 part pv.01 --size=1000 --grow volgroup cl pv.01 logvol swap --fstype swap --name=swap --vgname=cl --size=2048 logvol / --fstype ext4 --name=root --vgname=cl --size=1 --grow Importing the .ova again to Amazon, selecting the same storage size of 100GB for the root volume, I finally got what I wanted: [root@localhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/cl-root 94G 2,3G 87G 3% / devtmpfs 15G 0 15G 0% /dev tmpfs 15G 0 15G 0% /dev/shm tmpfs 15G 8,3M 15G 1% /run tmpfs 15G 0 15G 0% /sys/fs/cgroup /dev/xvda1 983M 154M 762M 17% /boot tmpfs 3,0G 0 3,0G 0% /run/user/1000 So I found **WHAT** is going on, but not **HOW** it happens. The questions are: - The kickstart file is supposed to be used only in installation time. How after Amazon VM import the file system get changed using the same conventions of the kickstart installation? - Where this info is stored, and how the resizing is being done automatically in CentOS 7?

How do I use the thufir profile I created, and not use the AWS root account? I'm on page 12 of the _AWS Command Line Interface User Guide_: thufir@doge:~$ thufir@doge:~$ cat .aws/config [default] output = text region = us-west-2 [profile thufir] role_arn = arn:aws:iam::1234567890:user/thufir source_profile = default thufir@doge:~$ thufir@doge:~$ aws iam list-users USERS arn:aws:iam::1234567890:user/thufir 2017-01-02T10:09:01Z / ABCDEFGIJKL thufir thufir@doge:~$ thufir@doge:~$ aws s3 ls --profile thufir An error occurred (AccessDenied) when calling the AssumeRole operation: Roles may not be assumed by root accounts. thufir@doge:~$ thufir@doge:~$ export AWS_DEFAULT_PROFILE=thufir thufir@doge:~$ thufir@doge:~$ aws s3 ls --profile thufir An error occurred (AccessDenied) when calling the AssumeRole operation: Roles may not be assumed by root accounts. thufir@doge:~$ [Page 12 of the _AWS Command Line Interface User Guide_](http://docs.aws.amazon.com/cli/latest/userguide/cli-roles.html#cli-role-prepare) says:

After creating the role, modify the trust relationship to allow the IAM user to assume it. The following example shows a trust relationship that allows a role to be assumed by an IAM user named jonsmith :

{
  "Version": "2012-10-17",
  "Statement": [
  {
    "Sid": "",
    "Effect": "Allow",
    "Principal": {
      "AWS": "arn:aws:iam::123456789012:user/jonsmith"
    },
  "Action": "sts:AssumeRole"
}

Is that done locally in a config file physically on my machine, or through a website, or...? *I think this may relate to roles rather than a **profile** as I have configured.*
