Fixed "Apache2 Startup warning: NameVirtualHost *:80 has no VirtualHosts"

Based on the information from the following two links, I could remove this annoying error message in my linux box by commenting out the first line (i.e., "NameVirtualHost: *:80" ) in "/etc/apache2/ports.conf":

Automatic Mount/Unmount Novell NetWare Shares in Linux

Purpose

• Automatically mount Novell NetWare shares without prompting passwords when logging in.
• Automatically unmount Novell NetWare shares without prompting passwords when logging out.

Configurations

• "$HOME/.nwclient"
  
• Create the file with permissions of "0600".
• Add "Server/User Password" pair per each line as follows:
  

  NW_Server1/NW_UN1 PW1
  NW_Server2/NW_UN2 Password2
  

  where "NW_UN1/2" could be either just a NetWare username or
  a NetWare username appended by its context (e.g.,
  "joe.ee_dept.eng_school.great_univ").
  
  
• "$HOME/.bash_profile"
• Add "ncpmount" command as follows:
  

if [ ! -d /mount/point1/dir1_in_mounted_share ]; then
# Check the above to prevent duplicate mount.
ncpmount -S NW_Server1 -U NW_UN1 -u Linux_UN -V path/to/subdirectory1 -A NW_Server1_DNS_Name /mount/point1
fi
# We need "-m" below to allow multiple mounts from the same server.
if [ ! -d /mount/point2/dir2_in_mounted_share ]; then
ncpmount -S NW_Server2 -U NW_UN2 -u Linux_UN -V path/to/subdirectory2 -m -A NW_Server2_DNS_Name /mount/point2
fi
if [ ! -d /mount/point3/dir3_in_mounted_share ]; then
ncpmount -S NW_Server2 -U NW_UN2 -u Linux_UN -V path/to/subdirectory3 -m -A NW_Server2_DNS_Name /mount/point3
fi



• "$HOME/.bash_logout"
  
• Add "ncpumount" command as follows:
  

 if [ `w | grep pts | grep Linux_UN | wc -l` -eq 1 ]; then
# The following will be executed only when this shell is the last login shell.

if [ -d /mount/point1/dir1_in_mounted_share ]; then
ncpumount /mount/point1
fi
if [ -d /mount/point2/dir2_in_mounted_share ]; then
ncpumount /mount/point2
fi
if [ -d /mount/point3/dir3_in_mounted_share ]; then
ncpumount /mount/point3
fi
fi

Linux Programming Environment Settings in Windows XP (with VMware)

• GNU Emacs color settings & syntax highlighting for 256-color terminals (with PuTTy and screen):
• See EmacsWiki: PuTTy for PuTTy settings.
• Just change "xterm-256color" to "putty-256color" in "terminal-type-string".
  
• Install "xterm-256color.el" under "lisp/term" directory.
• Create "putty-256color.el" having the following line in the same directory:
• (load "term/xterm-256color" nil t)
  
• Install (from source) 256-color-enabled "screen".
• Add "term putty-256color" in "$HOME/.screenrc".

• Static IP address with NAT for Ubuntu server in VMware:
• Update "interface" file under "/etc/networking" as follows:
• From:
  

  
  iface eth0 inet dhcp
  

  
  
  
• To:
  

  
  iface eth0 inet static
  address xxx.yyy.zzz.abc
  gateway xxx.yyy.zzz.2
  netmask 255.255.255.0
  network xxx.yyy.zzz.0
  broadcast xxx.yyy.zzz.255
