Acabei de atualizar do Ubuntu 12.04 para 12.10. Antes disso, fiz o backup da minha configuração autofs, que funcionou bem. Anexei a linha do antigo /etc/auto.master
para o novo:
+dir:/etc/auto.master.d
+auto.master
/mnt /etc/auto.sshfs uid=1000,gid=1000,--timeout=30,--ghost,--verbose
minha /etc/auto.sshfs
aparência assim:
mymount -fstype=fuse,rw,nodev,nonempty,noatime,allow_other,max_read=65536 :sshfs\#myuser@mydomain:/mnt/mymount
Tentando isso manualmente eu consegui, Connetion reset by peer
então eu adicionei a opção IdentityFile=/home/myuser/.ssh/id_rsa
. Agora isso acontece quando tento acessar /mnt
(com manual e autofs):
myuser@laptop /mnt % la
ls: cannot access mymount: No such file or directory
total 4
drwxr-xr-x 3 root root 0 Oct 19 10:34 ./
drwxr-xr-x 25 root root 4096 Oct 18 23:17 ../
d????????? ? ? ? ? ? mymount/
As entradas relevantes da minha /var/log/syslog
são as seguintes:

Eu já verifiquei o UID e o GID e eles correspondem ao meu usuário. As chaves SSH para o meu usuário estão no lugar. Eu também tentei criar /mnt/mymount
manualmente, mas estranhamente retorna "permissões negadas", mesmo enquanto root, enquanto o autofs estiver em execução (acho que deve ser assim).
Alguma idéia do que pode estar errado? Por uma etapa de configuração, esqueci o que fiz antes.

coisa?Respostas:
Existem algumas armadilhas que podem causar problemas. Até o momento desta resposta, você já havia resolvido uma delas, mas eu as acertarei em todas (seu problema atual está sendo causado pelo # 3).
1 - O arquivo de identidade
Este é o que você resolveu. Ao executar a
sshfs
partir de uma montagem autofs,sshfs
é executado como usuário root, portanto, usa a chave ssh do root por padrão. Você precisa especificarIdentityFile=/home/user/.ssh/id_rsa
para usar uma chave diferente.2 - hosts conhecidos
Também porque você está executando
sshfs
como um usuário diferente daquele que você normalmente faz, é necessário garantir que o host remoto que você está montando esteja noknown_hosts
arquivo. Existem algumas maneiras de resolver esse problema.StrictHostKeyChecking=no
. Isso fará com que o ssh aceite qualquer chave que ele veja (portanto, introduz um pouco de insegurança).UserKnownHostsFile=/home/user/.ssh/known_hosts
. Isso fará com que você use oknown_hosts
arquivo do seu usuário normal.3 - FUSE allow_other
Por padrão, um sistema de arquivos com fusível (que é o sshfs) não permite que usuários, além daquele que montou o sistema de arquivos, o acessem. Como o autofs é executado como root, por padrão, somente o root pode acessá-lo. Qualquer outra pessoa não terá permissões (mesmo root, se montada por um usuário não root), mesmo que as permissões de arquivo reais digam que deveriam. Para resolver isso, você deve adicionar a opção de montagem
allow_other
. Isso permitirá que outros usuários, além daquele que o montou, acessem o suporte. Embora o acesso ainda obedeça às permissões no nível dos arquivos na montagem.fonte
allow_other
opção já está no,/etc/auto.sshfs
como você pode ver na minha pergunta. Eu também uso ssh frequentemente, então a entrada de hosts conhecidos também está lá.known_hosts
você conferiu ? Do seu comentário sobre o uso do ssh com frequência, acho que você verificou o usuárioknown_hosts
. Você precisa verificar o root, pois ele está chamando o ssh.Você já tentou executar autofs com opções de depuração?
sudo automount --debug -f /etc/auto.master
fornecerá a saída de depuração para o terminal runnning.Você adicionou root E seu usuário ao grupo de fusíveis?
sudo gpasswd -a $USER fuse
fonte
/etc/auto.sshfs
arquivo.
