Enabling Local FS Quotas in Linux

Quotas allow you to limit the amount of space a user or group can use
and / or the number of files a user or group can create on a filesystem
(FS).  The following shows how to set up these quotas and the expected
user experience.  Our host details for this are:

Granting Elevated Privileges in Solaris

root, root, root, everybody always wants root.  Developers, application
administrators, users, they all seem to find a reason to "need" root
access.  Since normally these needs are for access to particular files
or to perform very specific tasks, only a subset of root's access is

Finding Open Files in Linux

Finding open files in Linux is quite similar to finding them in FreeBSD
and Solaris.  Here, we'll specifically identify open files on a particular
filesystem (FS) within a Linux environment.  Our host details this
time are:

Finding Open Files in FreeBSD

Following up the same in Solaris, here's how to identify open files on
a particular filesystem (FS) in a FreeBSD environment.  Our host details
for this are:

Finding Open Files in Solaris

During a recent discussion, another sysadmin asked that I write him a
tool to identify any open files on a particular file system (FS) in a
Solaris environment.  Rather than reinvent the wheel, I provided him
with the steps outlined here.  Our host details are:

updated utility, getldp.pl

An updated version of 'getldp.pl', v0.1.5, is now available on the
Tools page.  This version now appropriately handles VLAN tagged (802.1q)
CDP packets and includes output for duplex, 802.1q priority, and VLAN ID
(assuming the fields are present in the CDP packets):

Converting inet_aton and inet_ntoa

At some point or another, you've probably stumbled upon the 'inet_aton'
and 'inet_ntoa' functions.  Perhaps you have used them in programming,
or maybe for a MySQL statement, etc.  Briefly, for those not familiar
with either function, 'inet_aton' takes an IP address (10.234.18.76) and

Configuring NFS in FreeBSD

Having written up Solaris and Linux, it's time to take a look at
configuring NFS in FreeBSD.  Briefly, NFS (network file system) provides
access to remote filesystems which appear similar to local resources
on client hosts.  The following focuses on simple NFS server and client
