I think I’m coming down with a cold. Meh. Several days, now, I’ve awoken with a sore throat, stuffy nose, coughing, etc. It eases up as the day goes on (yesterday, I started on Dayquil)…but it still sucks.
The semester’s winding down. Fortunately, today my class is doing presentations for their research projects, so I won’t have to talk a lot. My system administration class really was a joy this semester. The students were motivated and engaged. We hit a few roadblocks in labs, as I had to rewrite every lab to use Amazon Web Services instead of VMware, but, all-in-all, I think it was a win.
We’re moving forward with my attempt to enlarge the Linux footprint in the department with the formation of a Linux subcommittee under the student chapter of the ACM. There seems to be a lot of interest in Linux among the students, so I’m hopeful. Whether ‘interest’ translates into ‘participation’ remains to be seen. With such a high percentage of our student body being commuters, I’ve known it to be challenging getting groups together. But I’m hopeful.
Still been monitoring my logfiles on the 1710 web server with both amusement and bemusement. I wrote a bash script to extract unique IP addresses that are attempting to SSH in to the server and then do IP lookups. Over a week’s time, I had 148 unique addresses ranging from Greece to Russia, from Mexico to Brazil, all over the US (interestingly, a bunch resolved to AWS, Google, and Microsoft servers). Oh yeah, China. So there was my ‘light bulb’ moment with regard to disabling root login, since every Linux box has a root user. They’re not going to brute force my password, but why take a chance on some yahoo getting lucky?
Oh well. Might as well get in to work and prepare for the day. Ta!
