[Solved] sshfs connection: Nothing happens after password prompt

dbacc · 2015-02-19 20:02:32

Hey,

I'm trying to mount a remote folder via ssh.

User on the server side is different from local user.

After entering sshfs -C userserver@server:serverfolder clientfolder I get the password promptfor userserver. Then nothing more happens.

I've read the troubleshooting section of sshfs and , of course, shh connection is working.

But what is going wrong here?

What do you mean 'nothing happens'? A successful mount will not result in any output.

testing@caddywhompus:~$ sshfs alphaniner@crapshoot:/tmp /tmp/test            
Password for alphaniner@crapshoot:
testing@caddywhompus:~$ mount |grep test
alphaniner@crapshoot:/tmp on /tmp/test type fuse.sshfs (rw,nosuid,nodev,relatime,user_id=1000,group_id=100)

run the command with the verbose option.

EDIT: Actually the answer above me is better. Are you returned to a shell prompt with no output? Or does the command just hang, without ever actually returning?

Oh, sry. I mean that the command is never actually returning. And as far as I can see sshfs has no verbose option.

alphaniner · 2015-02-19 20:56:49

Hmm, you can try '-o sshfs_debug' and maybe '-d' for fuse debug. Note, with -d the command did not return me to a prompt, but the mount did work.

You can also specify ssh options:

$ sshfs -h
...
    -o SSHOPT=VAL          ssh options (see man ssh_config)

hmm, tried it with these options and LOGLEVEL=DEBUG3.

Now the output after the password prompt is:

I don't see the problem;)

is missing. You know ehere this part is generated?

alphaniner · 2015-02-19 21:58:35

Unfortunately, everything after the p/w prompt (just after "debug1: Next authentication method: password") is pretty much 'instantaneous'.

For reference, both machines are running Arch and are up to date.

ssh_config of client:

StrictHostKeyChecking no

sshd_config of server:

AuthorizedKeysFile      .ssh/authorized_keys
ChallengeResponseAuthentication no
UsePAM yes
PrintMotd no # pam does that
UsePrivilegeSeparation sandbox          # Default for new installations.
Subsystem       sftp    /usr/lib/ssh/sftp-server

my config looks pretty much the same. Connection works with other clients using e.g. OpenSuse. So this has to be a client issue. However, do you have any more ideas?

cris9288 · 2015-03-08 17:55:20

hm...what is the default shell of the user on the server? Check the .zshrc/.bashrc to see if there might be anything there that is causing that specific login to hang - if anything, back it up and start with a blank file. Are there other users on the server you can test with? Can you create a new user and try mounting the remote folder?

Another idea that comes to mind is the folder that you are trying to mount to on the client - can you try another folder? If you are mounting to /tmp/test, try /mnt/tmp/test.

dbacc · 2015-03-08 19:14:00

thats it! Used a fresh .bashrc and now its working. Thanks a lot!
