Hola chicos,
Hoy me gustaría compartir con ustedes un método seguro de administrar archivos entre sistemas. Apuesto a que escuchó sobre SCP o Copia segura, pero si no lo sabe, es un método cliente-servidor basado en SSH que puede permitir la transferencia segura de archivos de un host a otro.
Haré una demostración de cómo se puede configurar este protocolo en la serie de switches lan S5700 usando la interfaz de línea de comandos. Consideremos un escenario cliente-servidor, un conmutador será el servidor SSH y el segundo el cliente SSH.
Configuración del servidor:
#
aaa
local-user test password cipher %@%@Bi29HO<d{Bn*kPPc|>yQK<X3Akw3X'v%a6lsdT4r-Y@ ------test@12345678901234567890
M<X6K%@%@
local-user test privilege level 3
local-user test ftp-directory flash:
local-user test service-type ssh
#
#
scp server enable
ssh authentication-type default password
ssh user test
ssh user test authentication-type password
ssh user test service-type all
ssh user test sftp-directory flash:
ssh client first-time enable
ssh client 10.136.22.176 assign rsa-key 10.136.22.176
#
