[GUFSC] RTlinux

[Emílio Wuerges]

Primeiramente, acredito q esta nao e' a lista adequada para receber essa
mensagem. A descricao do problema esta ate' em ingles! Isso e' uma falta de
consideracao com muitos membros da lista, provavelmente.

Mas agora o seu problema:
Devido a mensagem de erro:

//--
 jordiRTLinux:/opt/rtldk-2.2/rtlinuxpro/lnet/bin # ./ping.rtl target=
138.100.76.1

dev0: PING (138.100.76.1)
ERROR: dev0 rtl_sendmsg() returned -301



The error information on the documentation says: 'Destination IP4 Address
not found in table'. But we don't know how to solve this problem.
//--

O erro provavelmente se deve a uma tabela de rotas mal configurada.
Poderia postar a tabela de rotas?
