function toCapital
{
   for x in $*
   do
      echo -n ${x:0:1} | tr '[a-z]' '[A-Z]' | xargs echo -n
      echo -n ${x:1} | tr '[A-Z]' '[a-z]' | xargs echo -n
      echo -n " "
   done
}

To test the function just call it:

Shell Script para cambiar de pasarela de Internet

El Problema

Cómo cambiar automáticamente de puerta de enlace (pasarela) sin tener que reconfigurar cada estación de trabajo en una red local (LAN) con dos accesos a Internet.



Solución

1. Instalar y configurar el demonio cron, editar el /etc/crontab para que ejecute cada minuto un scripts de comprobación y cambio atuomático de la puerta de enlace así:

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=”"
HOME=/

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
* * * * * root /root/switch-gw.sh

2. Luego ejecutar el comando chkconfig crond on

3. Finalmente ejecutar:
$ touch /root/switch-gw.sh
$ chmod 755 /root/switch-gw.sh

4. El contenido del archivo switch-gw.sh es el siguiente:

#!/bin/bash

#External direction to Internet
INTERNET=200.44.32.12

#Router ASDL
GW_ASDL=10.200.1.70

#Firewall Cisco PIX 506
GW_FR=129.1.1.69

#The result of one pinging
PING=0

#USE: change the default GW
#PARAM: $1 the new ip address
# $2 the new device for the ip address
#RETURN: none
function fswitch(){
echo “Switching…”
new_ip=$1
new_dev=$2
default_ip=`route | grep “default” | awk ‘{print $2}’`
default_dev=`route | grep “default” | awk ‘{print $8}’`
if [ "$new_ip" != "$default_ip" ]; then
route add -net 0.0.0.0/0 gw $new_ip dev $new_dev
route del -net 0.0.0.0/0 gw $default_ip dev $default_dev
fi
}

# USE: Ping to a host
# PARAM: $1 the host name
# RETURN: “0″ or “1″
function fping(){
ATTEMPS=3
PING=`ping -c$ATTEMPS $1 | grep ” 0% packet loss” | wc -l`
}

#Get the ip address of the gateway (gw)
#that you specified gateway in the arguments
if [ "$1" = "aba" ]; then
#is the first gw?
gw=$GW_ASDL
dev=”eth1″
else
if [ "$1" = "fr" ]; then
#is the second gw?
gw=$GW_FR
dev=”eth0″
else
#not found?, then get the actual default gateway.
gw=`route | grep “default” | awk ‘{print $2}’`
dev=`route | grep “default” | awk ‘{print $8}’`
fi
fi

#Testing ping to internet
fping $INTERNET

#Change the gateway if the current is not active
if [ "$PING" = "1" ] &&amp;amp; [ -z $1 ]; then
echo “Ping is OK, then no switching needed.”
else
#If no force then change to a new gateway
if [ "$2" = "force" ]; then
fswitch $gw $dev
echo “I’m forcing the switch to GW $gw on DEV $dev”
else
#Change to ASDL if default gateway is empty
echo “I’m trying to select an alternative gateway”
if [ -z "$1" ]; then
if [ "$gw" = "$GW_ASDL" ]; then
gw=$GW_FR
dev=”eth0″
else
gw=$GW_ASDL
dev=”eth1″
fi
fi
echo “Now I’m going to switch to GW $gw on DEV $dev”
fswitch $gw $dev
fi
fi
