Sftp with SSH

Daryl Much — Wed, 29 Oct 2008 12:56:23 GMT

Hello, I have created a process that uses sftp to connect to a remote system and authnticates with a key that I generated with ssh-keygen. The key is named id-dsa. When I watch the process with a -v i see it check parse a list of keys and it gets to that particular one can accepts it. My question is how do I hav a key named something other then id_dsa to be offered by the server? Thanks

hey,
see this
you can give dsa or rsa
Client
Steps: For SSH Without a Password

On the client run the following commands:
$ mkdir -p $HOME/.ssh
$ chmod 0700 $HOME/.ssh
$ ssh-keygen -t dsa/rsa -f $HOME/.ssh/id_d sa -P ''

This should result in two files,
$HOME/.ssh/id_dsa/rsa (private key) & $HOME/.ssh/id_dsa.pub (public key).
Copy $HOME/.ssh/id_dsa.pub to the server.

Server:
On the server run the following commands:
$ mkdir -p $HOME/.ssh
$ cat id_dsa.pub >> $HOME/.ssh/authorized_keys2
$ chmod 0600 $HOME/.ssh/authorized_keys2

Depending on the version of OpenSSH the following commands may also be required:
$ cat id_dsa.pub >> $HOME/.ssh/authorized_keys
$ chmod 0600 $HOME/.ssh/authorized_keys

An alternative is to create a link from authorized_keys2 to authorized_keys:
$ cd $HOME/.ssh && ln -s authorized_keys2 authorized_keys

On the client test the results by ssh'ing to the server:
$ ssh -i $HOME/.ssh/id_dsa/rsa server

(Optional) Add the following $HOME/.ssh/config on the client:
Host server
IdentityFile ~/.ssh/id_dsa
This allows ssh access to the server without having to specify the path to the id_dsa/rsa file as an argument to ssh each time

Shalom,

It would be easier to use scp for the file transfer. Also part of the openssh package which includes ssh sftp and scp

That's nice, but we can't see what you see
unless you show it to us.

Offered _by_ the server or _to_ the server?

I may not understand what you want. Are you
looking for something like "-i file" for
"ssh"? If so, sftp probably has a way to let
you specify the same thing.

It might also help if you mentioned your OS
version, and, perhaps, your SSH and/or SFTP
version(s).
