sshfs passwordless login

[Lakshmipathi]

Anyone here know,how to use sshfs without password. I need a equivalent of ssh -i command

As sshfs is built upon ssh, I would guess a normal key auth setup should do the trick.
i.e. if you can login via ssh without password,
sshfs should behave in the same way.

Thanks for your answer.One guy suggested me this

sshfs -o IdentityFile=~/.ssh/id_rsa

I'm using machine from amazon ec2.. normally i login using something like

ssh -i key.file root@ec2-zzz-xxx-xxx-y.compute.amazonaws.com

How to do that with sshfs I tried something like

sshfs -o IdentityFile= key.file key.pem root@ec2-zzz-xxx-xxx-y.compute.amazonaws.com

but it gave an error missing host see `sshfs -h' for usage

Any thoughts

Try this:

sshfs -o ssh_command="ssh -i key.file" root@ec2-zzz-xxx-xxx-y.compute.amazonaws.com

looks ugly as hell

I'm getting this error

Actually..

The usual way of using key auth is:
Create a ssh key pair on your machine with ssh-keygen
Then concat the content of your .ssh/id_rsa.pub to .ssh/authorized_keys2 on the remote machine

Can you try to get a passwordless login via ssh first by using the above?

In the mean time,I edited /etc/ssh/config and added alternate IdentityFile
and now when use ssh i can login without password

ssh user@xxx.yyy.aws.com

works
sshfs -o ssh_command="ssh" root@xx.yy.zz.amazonaws.com:/mnt/ /mnt
or
sshfs root@xx.yy.zz.amazonaws.com:/mnt /mnt

both gives
read: Connection reset by peer

[Lakshmipathi]

using running sshfs in verbose mode it says

subsystem request failed on channel 0
read: Connection reset by peer

I found this sloution
Sshfs - DD-WRT Wiki

But it didn't work.

Are you sure, the remote ssh server offers sftp?
