de monitoramento de redes
ele ainda esta sendo criado

estou testando a saida dele com o comando echo...

mas ele não sai o echo da função... oque ha de errado??

A primeira coisa é que a function deve estar num lugar antes da chamada dela no seu script ... tipo assim:

#!/bin/bash

#PARAMETROS
#----------------------------------------------------------
IPLNK=$1
IPSRV=$2
LOCK_OK=0
LOCK_LNK=0
LOCK_SRV=0


#FUNCTIONS
#----------------------------------------------------------
Spider_Trap_Lnk(){
while true; do

sleep 1
CONT=`expr $CONT + 1`
if [ "$CONT" -ge 3 ]; then
echo "Link Fora!!!! Segundo Aviso e Email"
CONT=0
fi

if ping -c 1 $IPLNK >> /dev/null; then
LOCK_OK=0
LOCK_LNK=0
break;
fi
done
}

Spider_Trap_Srv(){
while true; do

sleep 1
CONT=`expr $CONT + 1`
if [ "$CONT" -ge 10 ]; then
echo "Server Fora!!!! Segundo Aviso e Email"
CONT=0
fi

if ping -c 1 $IPSRV >> /dev/null; then
LOCK_OK=0
LOCK_SRV=0
break;
fi
done
}

#ROTINA PRINCIPAL

while true; do
if ping -c 1 $IPLNK >> /dev/null && ping -c 1 $IPSRV >> /dev/null; then

if [ "$LOCK_OK" -eq 0 ]; then
echo "Tudo OK!!!! Primeiro Aviso e Email"
LOCK_OK=1
else
sleep 2 #debug
echo "Aviso!! Aviso!! Aviso !!!"
fi
else
if ! ping -c 1 $IPLNK >> /dev/null; then

if [ "$LOCK_LNK" -eq 0 ]; then
echo "Link Fora!!!! Primeiro Aviso e Email"
LOCK_LNK=1
else
Spider_Trap_Lnk
fi
else
if ping -c 1 $IPLNK >> /dev/null && ! ping -c 1 $IPSRV >> /dev/null; then
if [ "$LOCK_SRV" -eq 0 ]; then

else
Spider_Trap_Srv
fi

done

Acho que este é um dos seus problemas ... se ainda der erro avisa.

Eu organizei o Codigo... ...

Todo Com Funções....
eu pesquisei no google em muitos sites gringos e
vi que tem que declarar mesmo as functions e depois invocar elas...

Tu tens razão fdmarp

ai vai o codigo refeito;

da uma analizada....

#CHAMA A FUNÇÃO PRINCIPAL

Spider_Web

# FIM

Cara ... testei aqui e funcionou legal!!!!

Fiz umas sugestões no seu script, buscando melhorar a performance ... mas não sei se pra vc funciona, né! ... ai vc quem avalia.

A maior mudança foi na estrutura do Spider_Web
=> cada vez que o ping -c aparece no if ele é executado realmente, então na Spider_Web vc
validava "if ping -c 1 $IPLNK >> /dev/null && ping -c 1 $IPSRV >> /dev/null"
se a resposta fosse não ... ai validava "if ! ping -c 1 $IPLNK"
se a resposta fosse não ... ai validava "if ping -c 1 $IPLNK" e "if ! ping -c 1 $IPSRV"

=> mudei para: verifica se o link falhou, se não ... verifica o server ... se não ... tudo OK

Espero ter ajudado ... precisando ... tamos ai!!

# FIM

Hoje é feriado e eu não to no trabalho pra verificar o script
mas eu vi que foram meio que radicais as mudanças nele...
principalmente nas funções filhas...
aquela ideia do $ALERT_TIME foi otima...
e a Spider_Web ficou mais enxuta mesmo....
eu vou dar umas modificadas....

mas como diz Murphi... quando tu axa a solução de um problema aparecem mas 10 piquenos problemas.... lá vai...

Dada a seguinte situação...

Imagina um rede com mais de 50 filiais.. este script funciona bem para o link de 1 loja....

eu terei que criar um outro shell Maior chamando os sub shells de cada lojas e retornando 3 valores, OK, LINK OFF ou SERVER OFF...

e ainda criar um interface ou no Terminal com cores... vere amarelo e vermelho... ou uma CGI em HTML ou PHP, fora o sendmail horrivel de configurar...

pow fico grande esse negócio, por 300 mango eu faço isso numa boa, me da umas 2 horas e duas latinhas de cerveja e fica pronto heheh

Valeu fdmarp ...

ja foi de grande apio tuas ideias...
me deram uma grande clareada e eu não vou pagar 300 pila pra ninguem.... vou fazer na mão.. o software é livre a a ajuda é solidaria... porisso que a comunidade é forte!!

agora to pensando em desenvolver a front End.. mas é uma outra historia... Obrigado!

Você pode utilizar o mailx e o postfix para enviar emails.

que é isso, tava zuando, se eu tivesse tempo (pra estudar tbm) até dava uma mãozinha!
Boa sorte
