Generalidades en Ubuntu y Centos

1. Si deseo saber el nombre del Pc uso el comando hostname, si quiero saber la ip, pe, mask y la MAC, uso el comando ifconfig, si quiero editarlas ejecutar en terrminal setup en centOS y en Ubuntu /etc/network/interfaces y para ver el detalle es route -n

sudo ifconfig eth0 10.0.0.100 netmask 255.255.255.0 sudo route add default gw 10.0.0.1 eth0

2. Si quiero ver que hosts, servicios y protocolos tengo que ver sus archivos, en este caso debo ejecutar el comando vi hosts, vi protocols, o vi services.

3. Si quiero activar un puerto, por ejemplo 6667 para que IRC no esté bloqueado entonces:

root@V20304:~# cd /etc/

root@V20304:/etc# gedit services

Nota: las ediciones sólo están permitidas si se ha logueado como superusuario sudo -i
