私はUbuntu 12.04から12.10にアップグレードしました。これを行う前に、autofs設定をバックアップしましたが、正常に動作しました。/etc/auto.master新しい行に古い行を追加します。
+dir:/etc/auto.master.d
+auto.master
/mnt /etc/auto.sshfs uid=1000,gid=1000,--timeout=30,--ghost,--verbose
私の/etc/auto.sshfs外観は次のとおりです。
mymount -fstype=fuse,rw,nodev,nonempty,noatime,allow_other,max_read=65536 :sshfs\#myuser@mydomain:/mnt/mymount
手動で試したConnetion reset by peerので、オプションを追加しましたIdentityFile=/home/myuser/.ssh/id_rsa。これで/mnt（manualとautofsを使って）アクセスしようとすると、これが起こります。
myuser@laptop /mnt % la
ls: cannot access mymount: No such file or directory

私の関連項目は/var/log/syslog次のとおりです。

UIDとGIDを確認した結果、私のユーザーと一致します。私のユーザーのSSHキーは所定の位置にあります。また、手動で作成しようとしましたが、/mnt/mymount奇妙なことに、autofsが実行されている間は「Permission Denied」（私の考えではそうする必要があると思います）が返されます。
どのアイデアが間違っている可能性がありますか？以前に忘れていた構成手順が必要です。
答え1
デバッグオプションを使用してautofsを実行してみましたか？
sudo automount --debug -f /etc/auto.master実行中の端末のデバッグ出力を提供します。
ヒューズグループにrootとユーザーを追加しましたか？
sudo gpasswd -a $USER fuse
答え2
問題を引き起こす可能性があるいくつかの問題があります。この回答を書いている時点で、あなたはすでに問題の1つを解決しましたが、すべての問題を解決します（現在の問題は＃3のために発生しました）。
1 - ID
これがあなたが解決する問題です。sshfsautofs マウントで実行するとsshfsroot として実行されるため、ルートの SSH キーがデフォルトで使用されます。IdentityFile=/home/user/.ssh/id_rsa別のキーを使用する場合は指定する必要があります。
2 - 既知のホスト
また、通常とは異なるユーザーとして実行しているため、インストールするsshfsリモートホストがそのファイルに存在することを確認する必要がありますknown_hosts。この問題を解決する方法はいくつかあります。
- リモートホストにルートとして一度SSHを介して接続し、リモートホストのキーを受け入れます。
- パラメータを追加します
StrictHostKeyChecking=no。これにより、sshに見えるすべてのキーが許可されます（したがって、少し不安が発生します）。 - パラメータを追加します
UserKnownHostsFile=/home/user/.ssh/known_hosts。これにより、known_hosts一般ユーザーのファイルが使用されます。
3 - ヒューズ許容_その他
デフォルトでは、ヒューズファイルシステム（sshfsなど）は、ファイルシステムをマウントしたユーザー以外のユーザーがアクセスすることを許可しません。 autofsはrootとして実行されるため、デフォルトではrootのみにアクセスできます。実際のファイル権限が許可する必要があることを示していても、他の誰も権限を持ちません（root権限を持つroot以外のユーザーがインストールしたユーザーも含まれます）。この問題を解決するには、マウントオプションを追加する必要がありますallow_other。これにより、インストールしたユーザー以外のユーザーがインストールにアクセスできます。ただし、アクセスはまだマウントされているファイルのファイルレベルの権限に従います。
