* 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

Here are some tips & tricks for Opera browser:

1. Download, extract, cd into directory

2. Compile & Install

    perl Makefile.PL
        make
        make install

the second method can be:

    perl -MCPAN -e shell
        install modulename

    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!

To capture the running state of the system. Start with the running processes on the system. Enter the following:

    (ps -aux; ps -auxeww; lsof) > current_procs.txt

Grab the contents of the /proc directory. Enter the following:

    tar -cvpf proc_directory.tar /proc/[0-9]*

Take a snapshot of the network state of the system. Enter the following:

    (date; uname -a; netstat -p; netstat -rn; arp -v) > network_status.txt

Take a snapshot of the currently active and kernel memory.

    dd bs=1024 < /dev/mem > mem
    dd bs=1024 < /dev/kmem > kmem

Taking a Disk Snapshot:

    dd if=/dev/hda1 bs=1024 > hda1
