comment Is there a hard limit of 65536 open TCP connections per IP address on linux?
@Chris what grawity said. The 5-tuple will have up to (but never reaching) 65536 combinations with the other machine. In reality, you'll never get there because a machine can't use any old port for a connection - some are reserved for specific reasons.

comment gzip without tar? Why are they used together?
@user36310 I know what you mean in principle, but in practice the tools let you extract a single file. tar -xzvf tarball.tar.gz single/file.txt. Behind the scenes it needs to do some extra work but for appearances it extracts a single file.

comment ssh banner per user
My Linux (Centos, a Redhat clone) uses /sbin/nologin as a shell in these situations, which reads /etc/nologin.txt as a message

Doesn't mount require root, or at least a root config change to make volumes mountable by non-root users?

comment Manual duplex (two-sided) printing of a PDF doc?
+1 for reverse pages. I do: print even pages, reverse pages, flip papers into paper tray, then print odd pages, no reverse pages.

comment is a CMOS battery rechargable?
@YuriKolovsky Mine died :) I had to replace it. They tend to run about 10 years or so, depending on use. Since most replace desktops every 3 or 4 years or so, you may never see it die. Even if they do die, you just have BIOS CMOS settings go to default, so you may not notice it.

+1 for Cygwin, though you can tune Cygwin setup.exe (somewhat) to limit all the extras of cygwin.
