Escolha do nome da equipe = Épsilon
Instalação do Servidor Ubuntu versão 9.10
- Usado o servidor DHCP do Laboratório Redes I para atualização dos serviços do servidor
sudo apt-get update
Instalando ssh
sudo apt-get install ssh
Configuração de teste na interface eth0
sudo ifconfig 200.135.37.115 netmask 255.255.255.0

Instalado Hotspot no servidor
wget http://nocat.net/downloads/NoCatAuth/NocatAuth-nightty.tgz
Configurado resolv.conf
vim /etc/resolv.conf domain REDES1 search REDES1 nameserver 200.135.37.65
- Sequencia de comandos para o hotspot
tar zvxf NocatAuth-x.xx.tar.gz cd NocatAuth-x.xx make gateway cd /usr/local/nocat vim nocat.conf *verifcado linhas 22 alterado GatewayName Epsilon 125 130 141 150 160 168 176 183 alterado como RoteOnly 1 193 201 alterado como MemberOnly 1 211 226
- Hotspot ainda precisa ser configurado em alguns tópicos.

Criado um script simples para salvar configurações já setadas até o momento:
#!/bin/bash nome=backup-txt-`date +%Y_%m_%d-_%H_%M`.txt touch $nome echo "**** INTERFACES DE REDE ****" >> $nome echo >> $nome ifconfig -a >> $nome echo >> $nome echo "**** ROTAS ****" >> $nome echo >> $nome route -n >> $nome echo >> $nome echo "**** Arquivo Resolv.conf ****" >> $nome echo >> $nome cat /etc/resolv.conf >> $nome echo >> $nome echo "**** HOTSPOT ****" >> $nome echo >> $nome cat /usr/local/nocat/nocat.conf >> $nome echo >> $nome echo "**** DNS ****" >> $nome echo >> $nome echo "/etc/bind/named.conf.local" >> $nome cat /etc/bind/named.conf.local >> $nome echo >> $nome echo "/etc/bind/epsilon.sj.ifsc.edu.br" >> $nome cat /etc/bind/epsilon.sj.ifsc.edu.br >> $nome echo >> $nome echo "/etc/bins/37.135.200.in-addr.arpa" >> $nome cat /etc/bind/37.135.200.in-addr.arpa >> $nome echo >> $nome
Adicionado ao Crontab a execução do script de backup simples e a sincronização do relógio do servidor:
vim /etc/crontab ### Backup 1 - Texto 20 22 * * * root /backup/scripts/txback.sh bash 00 12 * * * root /backup/scripts/txback.sh bash ### Backup 1 - Texto 20 22 * * * root /backup/scripts/txback.sh bash 00 12 * * * root /backup/scripts/txback.sh bash
