BackupPC usando rsync falha com “incompatibilidade de versão do protocolo - o shell está limpo?”

Acabei de instalar o BackupPC em uma caixa Debian para usá-lo como servidor de backup. Como você sabe, este software faz uso, entre outros, do rsync. Ao usar o opção rsync, falha.

Servidor: Debian Jessie. BackupPC 3.3.1 construído a partir da fonte, executado por usuário "backup-user". Rsync 3.1.2 construído a partir da fonte com o padrão opções.
Cliente: Debian Jessie. Rsync 3.1.2 construído a partir da fonte com o padrão opções.

Após a falha, o comando rsync usado pode ser encontrado nos logs do BackupPC. Tentando o comando em um shell, logado como o usuário do BackupPC, eu me deparo com isso "incompatibilidade de versão do protocolo - o seu shell está limpo?" erro. O comando é:

/usr/bin/ssh -q -x -l backup-user 192.168.10.20 /usr/local/bin/rsync
--server --sender --numeric-ids --perms --owner --group -D --links
--hard-links --times --block-size=2048 --recursive --ignore-times .
/home/backup-user/test

Adicionando algum verbose ao comando rsync enviado ao cliente, ele diz ( Observe a versão do protocolo remoto ):

FILE_STRUCT_LEN=24, EXTRA_LEN=4

(Server) Protocol versions: remote=168430090, negotiated=31
protocol version mismatch -- is your shell clean? 
(see the rsync man page for an explanation) 
[sender] _exit_cleanup(code=2, file=compat.c, line=178): entered rsync error: protocol incompatibility (code 2) at compat.c(178) [sender=3.1.2] 
[sender] _exit_cleanup(code=2, file=compat.c, line=178): about to call exit(2)

Parece que o 168430090 no protocolo remoto é o decimal representação para 0xA0A0A0A, mas nenhuma pista do que está escrevendo. Eu procurei por erros semelhantes na lista, mas tudo que encontrei se deve a coisas que eu já verifiquei.

No cliente, usando o script de depuração que encontrei no site rsync:

/usr/bin/ssh -q -x -l backup-user 192.168.206.103
/home/backup-user/rsync-debug --server --sender --numeric-ids --perms
--owner --group -D --links --hard-links --times --block-size=2048
--recursive --ignore-times . /home/backup-user/test

Aqui é onde o script é interrompido. Eu tenho que bater o retorno várias vezes no servidor. Então continua:

%pre%

Depois de algumas horas de pesquisa, não consigo descobrir o que está errado. Eu removi e verifiquei tudo o que poderia escrever qualquer texto (mensagem de boas vindas, .bashrc echos, passphrase e até mesmo o prompt do sistema) e rsync ainda é incapaz de reunir os arquivos. A conexão ssh é feita sem senha.

Eu também fiz o verdadeiro > teste do testfile, sem problemas:

%pre%

As linhas:

%pre%

Parece-me suspeito, mas também verificou as bibliotecas envolvidas.

As opções --server e --sender são adicionadas pelo BackupPC, mas não são supostas para ser necessário em um uso regular, como afirma a documentação do rsync.

Alguém encontrou o mesmo problema? Eu sei que geralmente isso é causado por algo escrever dados no terminal, mas com o script de depuração eu posso ver que é rsync o processo de escrever os dados.

Espero que esta informação seja clara o suficiente. Obrigado pelo seu tempo.

O BackupPC provavelmente está usando o módulo Perl File :: Rsync para se conectar ao cliente. Eu suspeitaria de um problema de bug ou compatibilidade neste módulo.

Existe um pacote de BackupPC para o Debian. Deve listar todas as dependências apropriadas. O pacote de origem pode listar dependências.

Eu geralmente prefiro os módulos compactados, pois eles são mais propensos a serem corrigidos regularmente. Se você quer construir a partir do código-fonte, considere baixar o pacote de compilação e substituir o tar de origem pelo seu próprio.
