Keeping track of Linux users: When do they log in and for how long?

The Linux command line provides some excellent tools for determining how frequently users log in and how much time they spend on a system. Pulling information from the /var/log/wtmp file that maintains details on user logins can be time-consuming, but with a couple easy commands, you can extract a lot of useful information on user logins.One of the commands that helps with this is the last command. It provides a list of user logins that can go quite far back. The output looks like this:$ last | head -5 | tr -s " " shs pts/0 192.168.0.14 Wed Aug 14 09:44 still logged in shs pts/0 192.168.0.14 Wed Aug 14 09:41 - 09:41 (00:00) shs pts/0 192.168.0.14 Wed Aug 14 09:40 - 09:41 (00:00) nemo pts/1 192.168.0.18 Wed Aug 14 09:38 still logged in shs pts/0 192.168.0.14 Tue Aug 13 06:15 - 18:18 (00:24) Note that the tr -s " " portion of the command above reduces strings of blanks to single blanks, and in this case, it keeps the output shown from being so wide that it would be wrapped around on Continue reading

IDG Contributor Network: IoT-enabled shipping containers sail the high seas improving global supply chains.

Global trade flows through shipping containers. Manufacturers depend on them to get raw materials in time and to ship finished products to market. IoT is being applied to monitor containers and make sure that their contents aren’t damaged or stolen.Inter-modal containers Containers have standardized dimensions, which lets transporters easily ship, stack and store them. There are over twenty million containers in motion right now. Containers are pre-filled which reduces the time that trucks need to get loaded. Their standard size allows them to be easily transferred between trucks, planes, ships and trains.Global supply chains based on containers enable manufacturers to minimize their costs with ‘just-in-time’ inventory. This makes it important to track containers’ location and the condition of their contents.To read this article in full, please click here

Cloudflare Global Network Expands to 193 Cities

Cloudflare’s global network currently spans 193 cities across 90+ countries. With over 20 million Internet properties on our network, we increase the security, performance, and reliability of large portions of the Internet every time we add a location.

Expanding Network to New Cities

So far in 2019, we’ve added a score of new locations: Amman, Antananarivo*, Arica*, Asunción, Bengaluru, Buffalo, Casablanca, Córdoba*, Cork, Curitiba, Dakar*, Dar es Salaam, Fortaleza, Göteborg, Guatemala City, Hyderabad, Kigali, Kolkata, Male*, Maputo, Nagpur, Neuquén*, Nicosia, Nouméa, Ottawa, Port-au-Prince, Porto Alegre, Querétaro, Ramallah, and Thessaloniki.

Our Humble Beginnings

When Cloudflare launched in 2010, we focused on putting servers at the Internet’s crossroads: large data centers with key connections, like the Amsterdam Internet Exchange and Equinix Ashburn. This not only provided the most value to the most people at once but was also easier to manage by keeping our servers in the same buildings as all the local ISPs, server providers, and other people they needed to talk to streamline our services.

This is a great approach for bootstrapping a global network, but we’re obsessed with speed in general. There are over five hundred cities in the world with over one million inhabitants, but only a handful Continue reading
