problem doing sshfs mount with public key authentication
 

Hi,

I'm having trouble mounting over sshfs with public key authentication instead of password authentication (need this to do an automount).

I managed to get ordinary ssh logins to not require a password:

sambatyon@machina ~ $ ssh sambatyon@filer
sambatyon@filer ~ $

However, when I try mounting with sshfs I get the following:

sambatyon@machina ~ $ sudo sshfs sambatyon@filer:/shares/internal/backup /mnt/backup -o PasswordAuthentication=no
read: Connection reset by peer

I ran strace and got the following (relevant text only):

socketpair(PF_FILE, SOCK_STREAM, 0, [3, 4]) = 0
clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0xb7d766f8) = 10137
--- SIGCHLD (Child exited) @ 0 (0) ---
waitpid(10137, NULL, 0) = 10137
close(4) = 0
writev(3, [{"\0\0\0\5\1\0\0\0\3", 9}], 1) = 9
read(3, 0x80540d0, 9) = -1 ECONNRESET (Connection reset by peer)
dup(2) = 4
fcntl64(4, F_GETFL) = 0x2 (flags O_RDWR)
fstat64(4, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 3), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7fcc000
_llseek(4, 0, 0xbfcce6b8, SEEK_CUR) = -1 ESPIPE (Illegal seek)
write(4, "read: Connection reset by peer\n", 31read: Connection reset by peer
) = 31
close(4) = 0
munmap(0xb7fcc000, 4096) = 0
exit_group(1) = ?
Process 10136 detached


Any ideas?

I suspect that since you run the command with sudo it inherits some of sudo properties.
Run the sshfs sambatyon@filer:/shares/internal/backup /mnt/backup without "sudo"

The easier way would be to add the user sambatyon to group "fuse". You can then execute the command without sudo.
