{FlexLM} (now officially FlexNet Publisher) is the industry-standard software license management system developed by Flexera. It controls, monitors, and optimizes application usage across networks, typically utilizing a floating (concurrent) license model where a central server manages a pool of licenses for multiple users. It supports node-locked licenses, manages license files (often found at C:\flexlm\license on Windows), and allows for vendor-specific configurations.

OpenSSL 1.1.0 required

Ubuntu 24 fails with:

$ ./getiolid
./getiolid: /lib/x86_64-linux-gnu/libcrypto.so.1.1: version `OPENSSL_1_1_0' not found (required by ./getiolid)

Cause: Ubuntu 24.04 (Noble Numbat) does not include libcrypto.so.1.1 in its official repositories because it has migrated to OpenSSL 3.0. You must manually install the legacy libssl1.1 package to obtain this file.

One solution: (no longer exists)

curl -O http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2.22_amd64.deb
dpkg -i libssl1.1_1.1.1f-1ubuntu2.22_amd64.deb

# also works: libssl1.1_1.1.1w-0+deb11u1_amd64.deb.md5sum

Docker Ubuntu 24 needed:

apt install sudo curl libterm-readline-gnu-perl libterm-ui-perl dmidecode iproute2
