There doesn't seem to be any pattern or timing. As I sit and watch "top" I see it pop up to the top occasionally. I'm surprised by the CPU utilization when it does appear.
I tried Googling for an answer about the topic of this post, but almost all threads led me to topics on "WooCommerce" for Wordpress. This matter involves a process/command called "wc" that occasionally spikes my CPU utilization dramatically. Can only shed light on this service and why it might...
@f33dm3bits ... I didn't see this question until just now. Sorry for the delayed response. I'm a general I.T. consultant. 99% of my time is spent dealing with Windowz and OSX systems. I maintain a Debian server for Web hosting clients. Since OSX is linux-based, I occasionally need to drop into...
Howdy, I'm a transplant from the U.S. living in Switzerland. I've been tapping on keyboards since the early 80's. Most of my time has been spent working on Macs and Windows machines, but I occasionally (very occasionally) dip my toes into the world of Linux. I joined linux.org because I wanted...
@f33dm3bits ... it's been a couple of days since I implemented the changes you suggested. The maddening crush of 'root' login attempts have almost entirely stopped. I assume the bots or their maintainers realized things had changed and they've backed away. There are still lots of attempts using...
@f33dm3bits ... this has been extremely helpful. Many, many thanks! I have followed your guidance and have verified that the 'root' account is excluded from logging in with simple password authentication. Cert-based login is working like a charm for console and FileZilla. Sudo is working great...
So I installed sudo and now face an inconvenience. I use FileZilla to up/download files to the server. When logged in as a sudo-enabled user my actions are restricted because.... sudo.
There appear to be work-arounds, but they create additional steps that involve moving files into directories...
Thanks @f33dm3bits
This host is using Debian 9
I already did steps 1 & 2 of your instruction however instead of using...

I used this instead...
usermod -aG sudo username
The user is able to log in via SSH but isn't able to do much of anything. Once logged...
Thanks for your replies. Again, I'll reiterate that I'm not fluent with linux, so please lend your patience with the following...
I did some research and found some articles explaining how to create a new user and add them to sudo users. Problem is... I don't think sudo is even currently an...
Semi-Newbie, first-time poster here...
I manage a linux server that faces the public Internet. Every day there are thousands-upon-thousands of SSH login attempts on the "root" account (40,000 in the last several days). Within that sample are about 600 unique IPs that are attempting to...
