Depois de atualizar um servidor Ubuntu de 12.04 para 14.04, agora não consigo enviar arquivos (maiores) por scp . Além disso, bzr atualizações e confirmações de e para o servidor não são confiáveis, presumivelmente se a transferência total de dados exceder 600kb .
Estou com o mesmo problema descrito aqui (linkado de aqui ).
Nenhum dos respostas fornecidas para ou a questão resolveu o problema.
Nenhuma esta lista de soluções, nem Esta lista popular de soluções alternativas funcionou.
Além disso, 14.04 não está mais executando o kernel 2.4 ou 2.6.
Finalmente, estou incapaz de atualizar o servidor até 16.04.1 é lançado.
( Editar: Após algum tempo, o servidor foi atualizado para 15.10, mas o problema persiste.)
Sugestões?
EDIT: Em resposta a um comentário abaixo, o verboso scp log é aqui :
