Sort of. I work for a defense contractor, so we use an air gapped sytems. I log into gateway servers that run Solaris. Heck, until a few weeks ago, It was even on Sunrays thin clients. However, I then just ssh onto linux servers. I do occasionally support older prorgrams on solaris and other ancient unix systems. Found systems without Perl on it. And once got a bash error report that had some MIT email address.
