FaceTime Compatibility
FaceTime works over both WiFi and cellular networks. When it was first released, it only worked over WiFi because phone companies were concerned that video calls would consume too much bandwidth, leading to slow network performance and high data bills.
With the release of iOS 6 in 2012, that limitation was removed. FaceTime calls can be made over 3G, 4G, and 5G networks.
When introduced in June 2010, FaceTime only worked on the iPhone 4 running iOS 4. Support for the iPod touch was added in fall 2010, Mac in February 2010, and iPad in March 2011 (starting with the iPad 2).
FaceTime is an Apple technology and therefore only runs on Apple devices. You can't run FaceTime on Android, and there's no Windows FaceTime to download. However, there are plenty of other video and audio calling apps for those devices.
Set up the right Live Patching path for SLES 16.0 or 15 SP7, apply eligible kernel fixes, and confirm what is active without confusing it with a reboot-required kernel update.
Load a custom SLES 15 kernel module without disabling Secure Boot. Match the running kernel, sign the .ko file, enroll a MOK key, and verify loading.
SLES 15 SP5 can migrate online to SP6, but each node must reboot. Use a tested rolling upgrade or blue-green cutover to keep workloads reachable.
Use SUSE’s supported STIG profile to scan SLES 15, test remediation, review remaining findings, and retain assessment evidence.
Trace a failed Cockpit connection through DNS, port 9090, the systemd socket, firewalld, TLS, and login settings using current SUSE guidance.
Create a redundant Ethernet connection on SLES 15 with YaST and Wicked, configure active-backup bonding, and verify both ports and failover.
Turn an existing SLES 15 system into a reviewed AutoYaST profile, validate it, and use it to deploy a test server with fewer manual steps.
Install the SLES 15 KVM and libvirt tools, enable the right host service, and configure selected virtual machines to start after a reboot.
Use systemd jobs and the previous boot journal to locate a slow service, mount, or storage dependency, then correct it without masking the cause.
Use firewall-cmd to inspect the active zone, allow HTTP safely, preserve SSH access, and verify that the rule survives a reload on SLES 15.
