connect to server and scp
Hi
I am using Ubuntu 10.04. I normally use Places => connect to server to copy files from another linux machine via ssh.
I have been given a login to a remote machine which i connect via the command line using this command
ssh -X -L 3316:localhost:3316 username@ipaddress
Apparently this login automatically connects to me to another machine (on the same network i think) via ssh
I dont know how to access this machine using 'connect to server' or scp
I tried using 'connect to server' via ssh with a port of 3316 but it fails with message
'cannot display location sftp://username@ipaddress:3316/ timed out when logging in'
I don't know how the -X and -L options from the above can be specified with the ubuntu connect to server feature or even scp
thanks

-L is for ssh tunneling.
It basically connect remote machine port 3316 to your local machine.
So you can access remote machine port 3316 by connecting to localhost:3316 once this tunnel is setup.
For direct ssh, you just do
ssh username@ipaddress
or
scp <files to copy> username@ipaddress:/path-t

Hi,
You do the SSH then the -X and -L are simply for forwarding ports to and from your system. So they are irrelevant in your case.
If you want to copy files you need to start SSH or SCP from your station..
With SSH retrieving files:
tar -czf - /path/to/localfiles | ssh hoastname tar -xzf - -C /local/path
With scp retreiving files:
scp username@hostname:/path/to
If you want to keep a directory in sync with a remtote server you can use rsync over SSH:
rsync -ave ssh hostname:/path/to/remote/f
Cheers,
K.
scp /path/to/file
Cheers,
K.

ssh username@localhost -p 3316 will send the connection through the tunnel established on the -L 3316:localhost:3316
The system to which this connects depends on the rule on the remote system that binds the remote system's local port 3316.
With the connect feature in ubuntu you would use localhost and port 3316 to get to where you want to be.

thanks for your replies but i must be doing something wrong
in the command line i opened the ssh tunnel like so
ssh -X -L 3316:localhost:3316 username@ipaddress
I then went to Ubunut connect feature and selected ssh and entered
server: localhost
port: 3316
username
but got error "cannot display location sftp://username@localhost:3316 ssh program exited unexpectedly"
in the command line i opened the ssh tunnel like so
ssh -X -L 3316:localhost:3316 username@ipaddress
I then went to Ubunut connect feature and selected ssh and entered
server: localhost
port: 3316
username
but got error "cannot display location sftp://username@localhost:3316 ssh program exited unexpectedly"
What does the 3316 port on the remote server do?
If you want to reach serverc that is on the same network as serverb from servera, the connection from servera to serverb has to be:
ssh -X -L 3316:serverc:22 username@serverb
I think the tunnel you were setting up was from localhost on servera to loclahost of serverb.
-L [localhost]:localport:[rem
If [localhost] is omited, this means that the port is listened to on all interfaces of the local system, (0.0.0.0) is implied in the absence of a [localhost] which can be localhost (127.0.0.1) or name_of_server (IP).

i should point out that i tried the obvious first:
ssh username@server
and got permission denied when entering password
but this works fine
ssh -X -L 3316:localhost:3316 username@ipaddress
I also tried copying a file via scp
scp username@server:/remotepat
It asks for my password and then hangs - no file is transferred and I tried with a very small file

@arnold - i can't get hold of the person who set this up but I do know that when i log in to the remote server the login automatically ssh's to another machine, presumably on the same network

Simply try to use
ssh username@ipaddress
-L is for tunneling.
-X is for X server port forwarding.
If you want to do plain and simple ssh, you don't need these options.
