Checking the proxy server settings with Google Chrome on a Windows system
In Google Chrome on a Microsoft Windows system you can check or change the
proxy server setttings by the following steps within the Chrome browser.
Note: changing the proxy server settings by this means changes the system-wide
proxy server settings, so the configuration changes you make will also apply
to Internet Explorer.
Click on the "Customize and Control Google Chrome" button at the top,
right-hand side of the Google Chrome window. It is represented as a button
with 3 short horizontal lines on it.
Click on the "Show advanced settings" link near the bottom of the window.
Scroll down to the Network Settings section and click on
the Change proxy settings button.
That will open an Internet Properties window where you can
click on the LAN settings button, which will open a
Local Area Network (LAN) Settings window.
Check the checkbox next to "Use a proxy server for your LAN (These settings
will not apply to dial-up or VPN connections)."
Click on the Advanced button, which will open a
Proxy Settings window.
Put in the IP address and port number for the proxy server in the
"Proxy address to use" and "Port" fields. You will see four types of proxies
listed: HTTP, Secure, FTP, and Socks. The line where you will place the
IP address and port number will depend on which of those you are using.
Click on OK and then OK again at the
Local Area Network (LAN) Settings window, and again
at the Internet Properties window.
Note: tested on Google Chrome 39.0 on a Microsoft Windows system.
Finding files modified on or after a date on a Linux system
If you wish to find all of the files modified on or after a particular
date on a Unix/Linux system, you can use the
argument. E.g., suppose I want to find
all files with a .php extension modified on or after January 10, 2015 in the
current directory and any subdirectories. I could use the command below:
find . -name "*.php" -newermt 2015-01-10
-newermt argument, which is a form of
is explained below:
Compares the timestamp of the current file with reference. The
reference argument is normally the name of a file (and one of
its timestamps is used for the comparison) but it may also be a
string describing an absolute time. X and Y are placeholders
for other letters, and these letters select which time belonging
to how reference is used for the comparison.
a The access time of the file reference
B The birth time of the file reference
c The inode status change time of reference
m The modification time of the file reference
t reference is interpreted directly as a time
Some combinations are invalid; for example, it is invalid for X
to be t. Some combinations are not implemented on all systems;
for example B is not supported on all systems. If an invalid or
unsupported combination of XY is specified, a fatal error
results. Time specifications are interpreted as for the argu‐
ment to the -d option of GNU date. If you try to use the birth
time of a reference file, and the birth time cannot be deter‐
mined, a fatal error message results. If you specify a test
which refers to the birth time of files being examined, this
test will fail for any files where the birth time is unknown.

Using a Juniper Networks NetScreen Firewall as a DHCP Server
A Juniper Networks NetScreen firewall running the ScreenOS operating system
can also serve as a DHCP server. The firewall can be configured through
the firewall from a browser, but also has a command line interface, which
is accessible via a SSH
The DHCP configuration provided by the server upon DHCP client requests can
be configured via the command line interface where you can set
the DNS servers, gateway address, netmask, etc. or enable and disable the
DHCP server functionality in the firewall.
