Soy nuevo en Ubuntu y novato en redes. No puedo acceder a los hosts de la red local por su nombre desde mi servidor 13.10 (sin GUI) recién instalado. No está configurado como servidor DHCP. Utilizo un Netgear R6300v2 para el servidor DHCP.
Puedo enviar SSH al servidor por nombre (unix3) desde Winpro7 (192.163.1.3) desde la sesión SSH: puedo hacer ping a Google.com. No puedo hacer ping a WinPro7. Puedo hacer ping a 192.168.1.3 (WinPro7). dhclient está ejecutando ifconfig. bien ?
Aquí está el registro de la sesión SSH donde intenté obtener toda la información relevante.
