I need help with scp

kyros · 12-29-2011, 10:47 AM

Hi there...I have been trying to use scp on my macbook in order to transfer a file from the server to my macbook. This is what I'm typing on the command line:

Code:

scp -P 5699 kyros@serverIPAddress:some.file kyros@macbookIPAddress:~
ssh: connect to host serverIPAddress port 22: Connection refused

Please help

You have put the port down as 5699, Is that the ssh port number, if you have not chnged the ssh port number leave the 5699 off.

kyros · 12-29-2011, 10:55 AM

thats the port number

spiky0011 · 12-29-2011, 11:11 AM

It seems strange that it reports connection to port 22 refused

kyros · 12-29-2011, 11:13 AM

does it matter that I'm behind a router?

Sed_Awk · 12-29-2011, 11:47 AM

Does the server and/or client have firewalls? if so, you may need to open port 5699

Also, is the ssh deamon also running on kyros@macbookIPAddress

Because ssh sees it as you are trying to transfer a file from one ssh server to another ssh server. The ssh deamon may not be enable on the macbook side.

I usually transfer file(s) this way
scp -P 12345 user@IPADDRESS:~/foo .

For example, from a client machine, I transfer a file called foo from user@IPADDRESS:~/ to the current directory by the '.' sign

The ~ is for home directory. If the file resides elsewhere than use the absolute path.

Where do you get that from?? There is no need to run SSHD on the client.

well....I'm running an openSSH server on my ubuntu machine and connecting to the server via my macbook which are all on the same network. I'm not sure if I'm running a firewall...I never installed one unless it already comes installed on ubuntu 11.04 or macOSx.

I tried

Code:

scp -P 5699 kyros@serverIPAddress:~/file.name ./newFile.name

which all it does is copy the file.name back onto the server as newFile.name. ARG!!!

I know you don't need sshd on the client side. The reason I mentioned that is because kyros had

Code:

scp -P 5699 kyros@serverIPAddress:some.file kyros@macbookIPAddress:~

The item in bold may be appear to scp as another server because of the user name, the @ symbol and the IP address.

That's way I said I transfer files this way below which works for me

Code:

scp -P 12345 user@IPADDRESS:~/foo .

So, if you're on a client machine i.e macbook, open a terminal and type

Code:

scp -P 5699 kyros@serverIPAddress:some.file .

The file will be copied from kyros@serverIPAddress to the current directory of the client machine.

Is your server and client the same machine?

spiky0011 · 12-29-2011, 12:57 PM

Have you tried to ssh into the server, will it conect that way?

kyros · 12-29-2011, 12:57 PM

no....they're two completely different machines. I even tried logging on to my school's server and I am getting the same results

Yeah...I can connect to the server no problem.

spiky0011 · 12-29-2011, 01:29 PM

Can you try logging in to another (school) server from your server, instaed of from macbook?

kyros · 12-29-2011, 01:30 PM

i logged on to the school server via my ubuntu machine
