How is ssh2 installed for PHP 7.4 on Rocky Linux? - linux

I recently upgraded to Rocky. I am getting an error on a PHP SSH command that has worked for years. Everything I try fails for various reasons. I need to ssh from PHP. At this point I am not particular about the method used. This is the code used for ssh connections:
$ssh = ssh2_connect($ssh_domain);
if( ssh2_auth_password($ssh_user, $ssh_password) )
{
// send the command
}
but I get this error on the connect line:
Call to undefined function ssh2_connect()
I installed with
yum install libssh2-devel

What am I doing wrong? Did I install the wrong package? Maybe I need to install something else?

Let me know if there's more info I can provide in manner to help you help me.
Cheers.
when removing freeradius (either by apt remove freeradius or apt purge freeradius) mind that config files are a seperate package called freeradius-config
so to completely wipe freeradius and do a reinstall do:
apt purge freeradius freeradius-config
rm -rf /etc/freeradius/
apt install freeradius
After installation of freeradius, add the following lines at the end of the client.conf file to set the access of your client:
#vi /etc/freeradius/3.0/clients.conf
For Example :
client SWITCH-01 {
ipaddr = 192.168.0.10
secret = kamisama123
}
client LINUX-01 {
ipaddr = 192.168.0.20
secret = vegeto123
}
In our example, we are adding 2 client devices, both devices will offer a login promt to authenticate on freeradius server database.
Now, locate and edit the freeradius users configuration file:
Example:
# vi /etc/freeradius/3.0/users
Adding Your Username And Password Like below:
freerad1 Cleartext-Password := "freerad1234"
freerad2 Cleartext-Password := "freerad2123"
Now, Restart freeradius server :
# service freeradius restart
Now, test your radius server configuration file :
#freeradius -CX
you can Test your radius authentication locally on the Radius server using the following commands:
# radtest freerad1 freerad1234 localhost 0 testing123
Here is an example of a successful radius authentication:
Sent Access-Request Id 151 from 0.0.0.0:34857 to 127.0.0.1:1812 length 75
User-Name = "freerad1"
User-Password = "freerad1234"
NAS-IP-Address = 172.31.41.98
NAS-Port = 0
Message-Authenticator = 0x00
Cleartext-Password = "freerad1234"
Received Access-Accept Id 151 from 127.0.0.1:1812 to 0.0.0.0:0 length 20
We are using the freerad1 username and the freerad1234 password to authenticate the user account.
The testing123 is a default device password included in the clients.conf file.
Now, go to the Linux server included on the clients.conf configuration file as LINUX-01.
Install the freeradius-utils package.
# apt-get install freeradius-utils
Test your radius authentication remotely on the Linux server (LINUX-01 OR YOUR CLIENT YOU ARE ADDED ON client.conf) using the following commands:
# radtest freerad freerad1234 192.168.0.50 0 vegeto123
** Congratulations, Your Freeradius server is on the service **

Looks like docker does not want anyone to use this repo anymore. Probably they started issuing the error from today I guess.
Of course the two VMs do not have subscription-manager package installed, neither subscription attached, they don't need actually in our context, but why is there a mirror issue on one VM and not on the other, whose OS and system configuration is the same on both, except that they are locate in two different networks?
Looks like yum docker-engine querying came back to a normal state
Even docker project url curling is working without the warning message seen in my first post
Looks like the deployment process hit a bad state in the public repo and hence caused these errors.

Docker - Cannot build multi-platform images with docker buildx

I'm trying to build a multi-platform (amd64, arm64 and armv7) image using docker buildx. Since I'm using an amd64 machine running Ubuntu 18.04, I followed the instructions on the Docker website and installed qemu via:
sudo apt install qemu-user
However, a weird error appears when I execute the previous command. More specifically, there seems to be an issue with the binfmt-support service. Here's the full log:

Despite that, I tried to go on with the usual procedure, namely:

docker buildx inspect --bootstrap
Where the output of the last command is:

As you can see, "linux/amd64" and "linux/386" are listed as the only available platforms, however I would need to build the image for "linux/arm64" and "linux/arm/v7" platforms as well.
I've been looking for a solution to this problem for hours, though I didn't find anything that worked
------------------------------------ EDIT ------------------------------------
Looks like I was able to solve part of the issue by running:
sudo apt purge --auto-remove qemu-user qemu-user-binfmt binfmt-support
And then reinstalling them. In fact, running again this command:
sudo apt install qemu-user
gives no error at all:

However, part of the issue is still there, as the output after running these three commands:
docker buildx create --name mybuilder
docker buildx use mybuilder
docker buildx inspect --bootstrap
is the same as before, namely:
[+] Building 2.6s (1/1) FINISHED

Why is that? Why is it showing me linux/amd64 and linux/386 as the only available platforms?

The output of docker context ls is:

I've also tried to restart docker after qemu's installation, but to no success. Also, specifying the target platforms in the docker buildx command:
docker buildx build -t <mytag> --platform linux/amd64,linux/arm64,linux/arm/v7 --load .
results in this error:

By the way, my version of the kernel is 4.15.0-76-generic
Run the multiarch container first
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
docker buildx rm builder
docker buildx create --name builder --driver docker-container --use
docker buildx inspect --bootstrap
And you should have your alternate architectures.
Tagging on this answer in response to the first error. The commands have been updated per https://docs.docker.com/buildx/working-with-buildx/.
QEMU is a cross-platform emulator responsible for sourcing the binaries for different architectures (through the binfmt_misc handler).
Will save some people some time to start with this command first:
docker run --privileged --rm tonistiigi/binfmt --install all
There are multiple binfmt packages, and there's a configuration that I think was missed when this question was asked.
For the various packages, I would opt for qemu-user-static over qemu-user-binfmt to avoid any dynamic linking issues. The two packages are doing the same thing, so you'll need to pick one or the other.
The next part should be fixed in current releases, but I think you were stumbling on this before. That's the fix binary or F flag you'll see when catting the files in /proc/sys/fs/binfmt_misc, e.g. see the F flag here:
$ cat /proc/sys/fs/binfmt_misc/qemu-arm

Details on what the F flag means can be found on this kernel.org post but the short of it is container namespaces include a different filesystem namespace, and trying to access the interpreter from that namespace will fail (unless you do something like bind mount /usr/libexec/qemu-binfmt into your container). Newer versions of the qemu packages automatically set this flag, so if your flags section doesn't have the F defined, see these bug reports for the version you'll need to upgrade to:
Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=868030
Ubuntu: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1815100
The easy button is to use the binaries from the multiarch image. This is good in CI if you have a dedicated VM (less ideal if you are modifying the host used by other builds). However if you reboot, it breaks until you run the container again. And it requires you to remember to update it for any upstream patches. So I wouldn't recommend it for a long running build host.
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
For github CI, add following plugin solve this for me
- name: Set up QEMU
id: qemu
uses: docker/setup-qemu-action#v1
with:
image: tonistiigi/binfmt:latest
platforms: all

user data is not running at launch aws ec2

I am trying to launch an ec2 linux instance (linux 2 ami) and while doing that in the user data, I am trying to
get node js installed, and at the same time install git.
Then I am trying to get clone my github repo and then start the node js server, all this done in the userdata.
I am trying to check everywhere, in the cloudlog init file to find some error why my user data is not working.
Here are the codes.
#!/bin/bash
sudo yum update -y
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.0/install.sh | bash
. ~/.nvm/nvm.sh
nvm install 4.4.5
sudo yum upgrade
sudo yum install git -y
git clone https://github.com/myname/one_user.git
cd one_user
dnsaddress=$(curl -s http://169.254.169.254/latest/meta-data/public-hostname)
export dns_name=${dnsaddress}
npm install -y
node server.js
The code below is from the cloud init log file.

Have you checked your SGs and NACL configurations? You need to allow port 80 (HTTP) and port 443 (HTTPS) in outbound SG rules - destination 0.0.0.0/0. You also need to allow the same on outbound NACL's rules and ephemeral ports on inbound rules. Makes sure that your instance is sitting in a public subnet (with route to IGW) and it has public/Elastic IPv4 attached to it.
If any one of those conditions is not met, your user data scrip will fail, since it need connection to the Internet (in your case).
If your instance is sitting in a private subnet, make sure that you are running NAT Gateway or NAT instance and that your route tables are properly configured, as well as SGs and NACLs. Also make sure that source/destination check is disabled on NAT instance if you are using it.
UPDATE
You log clearly says that you don't have npm and node installed so you need to pass installation instruction to the script as well.
npm install -y
is not the right way to install npm. You can follow these steps to install both node and npm.
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.0/install.sh | bash
. ~/.nvm/nvm.sh
nvm install 4.4.5
This will install node version 4.4.5. If you want some other version of node to be installed, then change the number for whatever supported version.

Your answer appears to be there in the text -- you're missing a Python package. Try running sudo pip install psutil, then restarting the agent. Can you add your agent version, OS and version, and how you installed the agent to your text as well? It looks like you're also using a very old version of the agent (it's up to 5.17.* for a number of OS's) so there may be better package bundling or critical updates since v. 4.4.0. Try installing a newer version as well.
Please find the required
[root#mudcsftpup01 ~]# sudo pip install psutil
Requirement already satisfied: psutil in /usr/lib64/python2.7/site-packages
