Do check out whether the expression is correct. In case, I leave a space after “Password: ” After I remove, the space, the error is gone. There is also a write-up in a form. Do take a look at Linux – spawn_id: spawn id exp6 not open
By default Linux uses up to 40% of the available memory for file system caching. After this mark has been reached the file system flushes all outstanding data to disk causing all following IOs going synchronous. For flushing out this data to disk this there is a time limit of 120 seconds by default. In the case here the IO subsystem is not fast enough to flush the data withing 120 seconds. As IO subsystem responds slowly and more requests are served, System Memory gets filled up resulting in the above error, thus serving HTTP requests.
If you just want to automate the Linux portion, here is something you may wish to consider.
Update the sshd_config Templates (The most important portion is that the “PasswordAuthentication no” and “ChallengeResponseAuthentication yes” is present. The whole sshd_config template is too large for me to put into the blog.
.....
.....
# To disable tunneled clear text passwords, change to no here!
#PasswordAuthentication yes
#PermitEmptyPasswords no
PasswordAuthentication no
# Change to no to disable s/key passwords
#ChallengeResponseAuthentication yes
ChallengeResponseAuthentication yes

Taken from Microsoft comes under blistering criticism for “grossly irresponsible” security – ars Technica
Microsoft has once again come under blistering criticism for the security practices of Azure and its other cloud offerings, with the CEO of security firm Tenable saying Microsoft is “grossly irresponsible” and mired in a “culture of toxic obfuscation.”
The comments from Amit Yoran, chairman and CEO of Tenable, come six days after Sen. Ron Wyden (D-Ore.) blasted Microsoft for what he said were “negligent cybersecurity practices” that enabled hackers backed by the Chinese government to steal hundreds of thousands of emails from cloud customers……….
Step 3: Install the Kernel-Headers and Kernel-Devel
The CUDA Driver requires that the kernel headers and development packages for the running version of the kernel be installed at the time of the driver installation, as well as whenever the driver is rebuilt.
To install the Display Driver, the Nouveau drivers must first be disabled. I use a template to disable it. I created a template called blacklist-nouveau-conf.j2. Here is the content
blacklist nouveau options nouveau modeset=0
The Ansible script for disabling Noveau using a template
Step 6: Reboot if there are changes to Drivers and CUDA
- name: Reboot if there are changes to Drivers or CUDA
ansible.builtin.reboot:
when:
- install_driver.changed or install_cuda.changed
- ansible_os_family == "RedHat"
- ansible_distribution_major_version == "8"
Aftermath
After reboot, you should try to do “nvidia-smi” commands, hopefully, you should see
You can use the ansible.builtin.file module. In my example below, I wanted to link the Module Environment profile.csh and profile.sh to be placed on the /etc/profile.d so that it will load on startup. Do take a look at the Ansible Document ansible.builtin.file module – Manage files and file properties
- name: Check for CUDA Link
stat: path=/usr/local/cuda
register: link_available
- name: Create a symbolic link for CUDA
ansible.builtin.file:
src: /usr/local/cuda-12.2
dest: /usr/local/cuda
owner: root
group: root
state: link
when:
- ansible_os_family == "RedHat"
- ansible_distribution_major_version == "8"
- link_available.stat.isdir is not defined and link_available.stat.isdir == False
You will need the latest GNU GCC-10 or the latest for a successful compile. I compiled with GCC-12.3. You may want to take a look at Compiling GCC 12.1.0 on Rocky Linux 8.5
If you are using OneAPI Intel MKL, you can use module use after compilation. It will not be covered in this write-up. But you can:
% module use /usr/local/intel/2023.1/modulefiles
Finally,
% module load mkl/latest
% module load gnu/gcc-12.3
% module load hpcx
% make veryclean
% make DEPS=1 -j
