[haeman]

I want to use scp to copy file from server A to server B , if I want the copying is via a specific port ( not use the default port ) , can advise what can i do ? thx

Hi,

you can use scp -P but on the other side ssh should listen that port number. so you should do appropirate changes.

u have to use -P option with scp


-P port
Specifies the port to connect to on the remote host. Note that
this option is written with a capital `P', because -p is already
reserved for preserving the times and modes of the file in
rcp(1).
Th ereceiver should receive on specified port no

[Steven E. Protter]

Shalom,

scp -p (permissions) -P

example
scp -p file.mine -P 22040 hostname:/destination

thx reply ,

when use scp -p file.mine -P 22040 hostname:/destination

it pop

-P: No such file or directory
22040: No such file or directory

what is wrong ? thx

[H.Merijn Brand (procura]

Do you have a very old or broken scp? scp's usage message should show the -P (capital P) usage

$ scp
usage: scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
[-l limit] [-o ssh_option] [-P port] [-S program]
[[user@]host1:]file1 ... [[user@]host2:]file2
$ ssh -V
OpenSSH_4.7p1, OpenSSL 0.9.8g 19 Oct 2007

Enjoy, have FUN! H.Merijn

[Sushil Srivastava]

Provide me the output of below command
#ssh -v

update the ssh pkg to get -P option .

[Suraj K Sankari]

Hi,

Try like this
scp file.mine -P 22040 hostname:/destination

As the usage line indicates, you must specify the options (including the -P option) _before_ specifying any files to copy.

i.e. the correct order of parameters is:

scp -P 22040 file.mine hostname:/destination

Or if you want to use the -p option to preserve the file times and permissions:

scp -p -P 22040 file.mine hostname:/destination

For this to work the other end's sshd needs to listen to that non-standard port.
But one reason why you asked might be that you would like SSH forward you a remote sshd's standard port to some local unused port because both hosts aren't allowed to communicate directly due to some firewall?
If you have an interim hop host that is allowed to ssh to the remote host, and if you have someone as an account thereon then you could scp via this hop through a tunnel.

Assuming port 2222 isn't in use on localhost you could build the tunnel like this
(note that the sleep has the advantage that you don't need to kill the tunnel when you're done (often forgotten) because it will shut down after 10 minutes).

$ ssh -NL2222:not_directly_reachable_host:22 someone@hop_host sleep 600

Once the tunnel is errected
(check by "netstat -anfinet|grep 2222.*LISTEN)
you can use the locally forwarded port 2222 and copy seemingly from localhost (remember that you need to supply the password of someone on remote host; also note that picking /dev/null as your local user's known_hosts file will prevent you from wrong host keys being saved for localhost)

$ scp -P 2222 -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no someone@localhost:/some/file/you/want/to.get /some/local/target

There's a typo in my SSH tunnel start command.
Of course, as you will have noticed, instead of
"$ ssh -NL..." it has to be "$ ssh -fL..."
-N would contradict the sleep command.
