IonutVanHow to install Microsoft Core Fonts on Suse 10.2
Installing Microsoft's TrueType core fonts for the web on any rpm based linux box with TrueType support is now easy:
I will show you a few solutions with the same final result :)
1. download the .spec file:
wget http://corefonts.sourceforge.net/msttcorefonts-2.0-1.spec
* build the binary rpm with:
rpmbuild -bb msttcorefonts-2.0-1.spec
* install the package:
rpm -ivh /usr/src/packages/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm
* reload xfs server
/sbin/service xfs reload
2. a)
Get the install script:
wget http://penguinfonts.com/packages/fetchmsttfonts.sh
* And run it as root:
sh ./fetchmsttfonts.sh
b)
Or you can build an rpm package, get the spec file:
wget http://penguinfonts.com/packages/msttcorefonts-2.0-1.spec
* Then build it:
rpmbuild -ba msttcorefonts-2.0-1.spec
* Then install the resulting rpm file:
rpm -i /usr/src/packages/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm
* reload xfs server
/sbin/service xfs reload
3. just download and install this package:
MicrosoftFonts-1-jen14.noarch.rpm
The fonts are: Andale Mono, Arial, Comic Sans MS, Courier New, Georgia, Impact, Times New Roman, Trebuchet MS, Verdana and Webdings. Andale, Courier New and Lucida Console are monospaced fonts that are suited for terminal apps.
Copy and pack your files into an ISO
To create the iso file do:
mkisofs -o /storage/myfiles.iso -J -R -r -V -v /dir/path/
Replace /dir/path/ with the full path to whatever directory contains the files you wish burned to CD.

Protect a web directory with password
vim /path/of/your/dir/.htaccess
Paste this into:
AuthType Basic
AuthName "Private Dir"
AuthUserFile /path/of/your/dir/.htpasswd
require valid-user
Then we must create the password file /path/of/your/dir/.htpasswd.
We want to log in with the username "user", so we do this:
htpasswd -c /path/of/your/dir/.htpasswd user
Enter a password for "user", and you're done!
