It's working fine now, which makes me think it's some kind of caching issue. I find it weird that Chrome could connect to palantir-02 yesterday, immediately, and the command line tools could not. I use iTerm2, which is a 3rd party terminal program that, so far, as exceeded the functionality of Apple's Term program, but I can't help but thinking that there might be some DNS caching being done somewhere that impacts the term programs and that Chrome doesn't deal with.
I have several learning disabilities and it's an attention span thing. It takes me longer to dig into something than it does for most people. There's a line and when I cross it, and dive deep into something, I can get a clear understanding of everything in it, but six months later, if I haven't kept working with that material, I can forget it all - unless I do another deep dive. So I've dealt with this kind of stuff before, but long enough ago, that I've forgotten all that's involved.
I probably should have looked up the command to clear the Mac's networking cache, but didn't think of it yesterday, when it would have helped. I did consider just rebooting, but didn't have the time while I was at the computer. (I figured that'd clear any DNS caching it may have done.)
I have been able to resolve anything with ping in the past - never an issue. I'm in a rural setting, so there are times I lose internet. I have a simple alias:
alias icheck='ping -c 5 8.8.8.8;echo;ping -c 5 www.google.com;echo;echo'
or something close to that, you get the idea. When I seem to be having connectivity issues, I always run that to see if our internet is down. I did run it just as a quick check (yesterday, when the issue was happening) and it did work.
