Guestshells running CentOS 7 will be unable to update or install system packages since the the default repositories have been deactivated (EOL).
This article shows how to configure and use "Vault" repositories if updating to a newer version of the NX-OS Guestshell running Rocky Linux is not an option.
Guest Shell is an LXC container that runs on Nexus switches (if enabled). Typically this separate execution space is accessed from the NX-OS CLI by typing guestshell. This article shows how to enable SSH within the Guest Shell so you can SSH directly to it.
This guide will show how to use/allow public key authentication for SSH connections to Cisco Nexus (NXOS) and Catalyst (IOSXE) switches.
Gnome’s Control Center region/locale settings are intentionally mutable/configurable by the user to set/determine the preferred formats, but Gnome Files (Nautilus) is not honoring the user chosen date format(s) when the Detailed preference is set for Date and Time Format.
Some time ago I wrote about my first venture into creating Jinja2 switch templates for FreeZTP. This is a follow up to that post after having an opportunity to revisit the process for another project.
Network security will always be more important than ever before.
This statement will remain true regardless of when this topic is discussed. Security is consistently being tested; whether it be voluntarily via hired penetration testing, or not so voluntarily by bad actors, or "BADDIES" herein.
Occasionally I'll post something here for the sole purpose of giving myself a point of reference for future configurations, or to simply fluff my post count since they're so infrequent. That being said...
On IOS switches with EEM, protect yourself (and less careful Jr engineers) with this applet that will prevent allowed-vlan-mishaps on trunks!
Time synchronization among network devices is important to consider when building out infrastructure, and not just within the datacenter; client endpoints, kiosk terminals, wireless controllers and associated access points, slot machine virtual bank controllers and their electronic gaming machines (EGMs, or slot machines), etc... All of these devices should be synced to the same time source, and done so in a secure method.
Considering gaming floor connectivity, the future has effectively already been here for some time. Serial connections are all but a bygone technology, any vendor worth their salt now supports Ethernet for EGM connectivity.
