Mainly concentrating here on getting openSSH running on Windows Install Cygwin and openSSH First, get the Cygwin installer (a single .exe). Run this, set the proxy and choose a mirror. When the install tree comes up we want to select: * openSSH (in the Net category) * nano (in the Editors category)

concentrating on servers... Initial setup Use the advanced setup option – allows you to specify the fixed IP address, proxy etc. Usually set up with one partition for the system, and another called /export0 for data. Sometimes use a separate /home partition as well.

Server (minimal/cli)

Minimal install really is minimal. Better to choose minimal and then add base packages - gives nano, ssh etc.

If this gives you Networkmanager - remove this:
yum remove NetworkManager
Use system-config-network to configure /etc/sysconfig/network-scripts/ifcfg-eth0

Debian

Quick test if mailx is installed:
echo "test" | mail -s "test" user@example.com
exim4

Check if exim4 is installed (or if not, if another mail system is installed!)

Use dpkg to do the configuration:
dpkg-reconfigure exim4-config
General type of mail configuration:

(Copied from )

NOTE that the default configuration uses \$ (dollar signs) to delimit TeX formulas.  This may cause trouble if you have \$ characters in any pages.  The default configuration also lets you escape the dollar signs, however, by changing them to \$.  This should correct any problems you might have.

Inline Math

Use dollar signs:



or escaped parentheses:



Display Math

To display math on its own line, use double dollar signs:



or escaped square brackets:



A wide range of math environments1) will work as well:



Note that the math environments should not be inside the dollar sign delimiters; the environments should stand on their own with just the \begin and \end statements in order to be parsed correctly.

Preamble

From Iain Sim's email

The old system of wireless network in the Kelvin building is being withdrawn and replaced with a much more sophisticated wireless mesh system from Ubiquiti. With this system it should be possible to roam anywhere (almost) within the building without losing connectivity.
