nohup e SSH

[Lucas Queiroz]

Eu estou tentando usar um programa por SSH, que eu compilei, chamado de a.out, mas toda vez que eu desconecto da conta, ele para de rodar, apesar de eu usar o nohup. O a.out não escreve nada na tela, só quando termina escreve um arquivo final.dat.

Um exemplo de como rodei:

Estou usando o Putty em um Windows XP

Sugestões:

1. Além do nohup, use o comando "disown" pra desassociar o processo do terminal.

2. Use o comando "screen" pra associar o terminal a uma tela que pode ser preservada entre uma sessão e outra.

-------------

Enquanto isso... como vc sabe que o programa está sendo interrompido, em vez de terminar normalmente?

[Lucas Queiroz]

Quando ele termina ele abre um arquivo. Estou usando o screen, nem tentei o disown. Só para futura referência, é só colocar "screen -r" depois, para ter a sua sessão de volta.
