Environment: CentOS 7.6.18.10, PuTTY rel. 0.71
Whenever I use PuTTY (on Windows) to connect to my CentOS box, I always get the message immediately after the authentication:
Couldn't get a file descriptor referring to the console
I decided not to ignore the message today, and figured out that setfont in my .bash_profile was causing it. I recall putting that in when I used to work from home more often and connect directly on console. Just nuke or comment out the line, and all is at peace.
