nfsportmon(8nfs)nfsportmon(8nfs)Name
nfsportmon - turn on or off the port monitor
Syntax
/etc/nfsportmon option
Description
The command turns the port monitor on or off at the kernel level. By default, the port monitor is turned off.
When the port monitor is on, NFS server port checking is activated. This checking increases system security by ensuring that file access
requests were generated by the client kernel rather than by a forged application program, for example.
Only the superuser or root can run
Options
on Turn on the port monitor.
off Turn off the port monitor.

mountd(8nfs)mountd(8nfs)Name
mountd - NFS mount request daemon
Syntax
/etc/mountd [-i] [-d] [-s]
Description
The daemon must be run on NFS servers to process NFS mount protocol requests. It reads the file to determine which file systems and direc-
tories are available to which machines and users, and makes this information available to the operating system. The machine names listed
in the file may optionally contain the local BIND domain name. For more information on BIND, see the Guide to the BIND/Hesiod Service To
see which clients have file systems or directories mounted, use the command.
Options-d If you are running the BIND/Hesiod service, after checking the Internet address, will verify that the host requesting a mount or unmount
is in the server's domain.
-i Turns on verification of the Internet address of the client against the server's database for mounts and unmounts. The default is no
address verification.
-s If you are running the BIND/Hesiod service, after checking the Internet address, will verify that the host requesting a mount or unmount
is in the server's subdomain.

I'm writing a command shell, and I want to be able to detect when the user presses an arrow key (otherwise it just prints [[A, [[B, etc.). I know it's relatively easy (although somewhat more time-consuming) to detect keystrokes in noncanonical mode, but I've noticed that the bash shell detects... (4 Replies)
I'm learning off Linux (Ubuntu) right now. I want to move up to Unix, but I don't want to rush like I did when it came to Windows --> to Linux. What is the best Unix OS that fits in pretty well with Ubuntu.
In other words is there kind of an equal Linux with Unix?

I noticed my hostname is <my-full-name>s-macbook.local. I'm not sure exactly what information leaves the local network, and whether the hostname is included, but if it is, this would mean people on the Internet can look at my hostname and see who I am. Before anyone says that's not possible,... (4 Replies)
