Network Presence Blog

After some 15 years of operation, I’ve decided to shutdown the public
retail cloud/VPS operations side of Network Presence.

The first phase of this is to quickly shutdown the Sydney POP, with the
last day of service from Network Presence in Sydney being February
28th.

I apologise for the inconvenience and I’m sorry to ask you to
please relocate your services provided by Network Presence asap and by
February 28th, as any service not migrated away from Network Presence
in Sydney by February 28th will no longer be available.

The Adelaide POP will continue to operate, but I won’t be offering
commercial-grade QoS and products in Adelaide from April 2026.

Any payments made to date for service beyond February will be refunded
and please cancel any Paypal Subscriptions or scheduled payments to
Network Presence.

I can understand you’d like to know why I’m doing this & its because
the Sydney POP and the retail public cloud side of Network Presence is
deeply unfinancial, and has been for some time, with costs increasing
substantially recently (year or so).

I’ve been happy to support it while doing mostly remote IT contracting
work around Adelaide. But my work is changing soon in 2026, and I can
no longer give the time, yet alone the funding, to operate this to the
public.

I’m available to discuss this with you and please let me know anything
you’d need me to action for you as I quickly stop providing these
services in my business.

I’ve enjoyed working with you and thank you for your business over
these years and I wish you all the best for your future endeavours.

Regards,
Richard.

Use the following command to get the full output from a recent service start attempt:

SYSTEMD_LESS=”FRXMK” journalctl -xeu $SERVICENAME

eg: # SYSTEMD_LESS=”FRXMK” journalctl -xeu httpd

‘tcp[tcpflags] & (tcp-syn) != 0 and tcp[tcpflags] & (tcp-ack) == 0 and dst port $PORTNUM’

We’re bringing online new VPS hosting servers (hypervisors) in our Adelaide POP, and moving some existing Adelaide POP customers to these new servers, with short outages for each customer VPS as these migrations occur.

This is possible after we’ve integrated our 2nd fibre based link to our Adelaide POP earlier this year.

These new servers in Adelaide will help host the growth that the POP is seeing.

Once again, like clockwork, it’s the season for multi-national companies to be raising their billing rates to Australians.

This time its our Sydney Data Centre, Equinix, increasing their costs to us by 5% from January, as is their contracted right & as they do every year without fail.

As per our other posts about such cost rises, we’d like customers to consider buying more VPS resources (eg: more CPUs or more RAM or more diskspace, etc) via our website, to help fund these cost increases, while giving more resources to your own VPS.

Regards,
Richard.

Redhat’s GPFS distributed file system is used in many HPC environments and is now known as IBM Storage Scale. It is not open-source software and can be downloaded from IBM’s sites. There is a Developer version which can be downloaded for trial use upon registering with IBM.

Here’s how to install the developers release version of IBM Storage Scale on an Alma Linux 9.6 operating system environment as of September 2025.

From a standard minimal install of Alma Linux version 9.6 (say from its ISO or an image template), which matches the newest currently supported kernel and software releases of IBM Storage Scale, see https://www.ibm.com/docs/en/storage-scale?topic=STXKQY/gpfsclustersfaq.html#fsi

Run the following commands to ensure you’re on the latest currently known working kernel version for GPFS/IBM Storage Scale, which at this date is
5.14.0-570.30.1.el9_6 in RHEL 9.6 or Alma Linux 9.6

dnf -y  update

dnf -y install kernel-devel-5.14.0-570.30.1.el9_6 kernel-5.14.0-570.30.1.el9_6 bzip2 gcc gcc-c++ make kernel-headers-5.14.0-570.30.1.el9_6 kernel-devel-5.14.0-570.30.1.el9_6 tar unzip zip

grubby --set-default /boot/vmlinuz-5.14.0-570.30.1.el9_6.x86_64

reboot

Once rebooted on this particularly kernel version with the build environment ready, you can run the “install” file supplied by IBM as the root user.
At the end of the installer’s run, part of it’s output will list:

To install a cluster manually: Use the GPFS packages located within /usr/lpp/mmfs/5.2.3.3/gpfs_rpms/

To do this, cd to the relevant directory for your RPM version Linux and run the dnf install command for the following list of package names:

cd /usr/lpp/mmfs/5.2.3.3/gpfs_rpms/

dnf -y install gpfs.base.rpm gpfs.gpl.rpm gpfs.license.dev.rpm gpfs.gskit.rpm gpfs.docs.rpm gpfs.msg.rpm gpfs.adv.rpm gpfs.crypto.rpm gpfs.docs.rpm gpfs.msg.rpm gpfs.adv.rpm gpfs.crypto.rpm

Now you can build the GPFS software suite and kernel modules with the single command provided by IBM, being: /usr/lpp/mmfs/bin/mmbuildgpl

# /usr/lpp/mmfs/bin/mmbuildgpl

Reimage your VPS with our Ubuntu 24.04 template.

Login to your VPS as root and run:

apt update && apt upgrade

Then install nodejs & npm with:

apt install nodejs npm

Now you can install claude-code with:

npm install -g @anthropic-ai/claude-code

With the above installed you can then run the “claude” command in your project’s directory, eg:

mkdir -p claude-project/1 && cd claude-project/1 && claude

Here’s the site where the old CentOS Linux Distros archive their final repositories.

http://archive.kernel.org/centos-vault/

Final command line is:

Where ~/.ssh/openssl.cnf is:

.include /etc/ssl/openssl.cnf
[openssl_init]
alg_section = evp_properties

rh-allow-sha1-signatures = yes

We’re installing a 2nd fibre link to our Adelaide POP.

This link will be through Vocus on physical separate & diverse fibre paths to our Adelaide POP and will allow greater Internet access redundancy & capacity for us in Adelaide.

This mirrors how we do our fibre connectivity to the Internet in our main Sydney POP and it will increase the level of service from our Adelaide POP.

This next fibre link in Adelaide will take a couple of months to get online now that it’s ordered & I’ll update when it’s close or online.

UPDATE from September 2025: This new link is online & working well for us.

Richard.
