There are many answers  but you should just be able to keep it simple  Make sure you know what port SSH is listening on  and define it  Here is what I just used to replicate your problem   scp -P 12222 file 7z user 193 168 X X  home user Downloads It worked out well

This can be achived by specifying port via the -P switch   scp -i   keys yourkey -P2222 file ubuntu host  directory

Copying  file  to  host  scp  SourceFile  remoteuser remotehost  directory TargetFile  Copying  file  from  host  scp  user host  directory SourceFile  TargetFile  Copying  directory  recursively  from  host  scp  -r  user host  directory SourceFolder  TargetFolder  NOTE   If  the  host  is  using  a  port  other  than  port  22   you  can  specify  it  with  the  -P  option  scp  -P  2222  user host  directory SourceFile  TargetFile

You know what s cooler than -P  nothing  If you use this server more than a few times  setup create a    ssh config file with an entry like   Host www myserver com     Port 80   or  Host myserver myserver80 short any name u want yes anything well-within-reason     HostName www myserver com     Port 80     User username   Then you can use   scp username www myserver com  root file txt    or  scp short  root file txt    You can use anything on the  Host  line with ssh  scp  rsync  git  amp  more  There are MANY configuration option that you can use in config files  see   man ssh config

Unlike ssh  scp uses the uppercase P switch to set the port instead of the lowercase p   scp -P 80       Use port 80 to bypass the firewall  instead of the scp default   The lowercase p switch is used with scp for the preservation of times and modes   Here is an excerpt from scp s man page with all of the details concerning the two switches  as well as an explanation of why uppercase P was chosen for scp      -P port  nbsp  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         -p  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  Preserves modification times  access times  and modes from the original file    Update and aside to address one of the  heavily upvoted  comments    With regard to Abdull s comment about scp option order  what he suggests   scp -P80 -r some directory -P 80            intersperses options and parameters  getopt 1  clearly defines that parameters must come after options and not be interspersed with them      The parameters getopt is called with can be divided into two parts  options which modify the way getopt will do the parsing  the options and the optstring in the SYNOPSIS   and the parameters which are to be parsed  parameters in the SYNOPSIS    The second part will start at          the first non-option parameter that is not an option argument  or after the first occurrence of  --    If no  -o  or  --options  option is found in the first part  the first parameter of the second part is used as the short options string    Since the -r command line option takes no further arguments  some directory is  the first non-option parameter that is not an option argument   Therefore  as clearly spelled out in the getopt 1  man page  all succeeding command line arguments that follow it  i e   -P 80      are assumed to be non-options  and non-option arguments    So  in effect  this is how getopt 1  sees the example presented with the end of the options and the beginning of the parameters demarcated by succeeding text bing in gray   scp -P80 -r some directory -P 80      This has nothing to do with scp behavior and everything to do with how POSIX standard applications parse command line options using the getopt 3  set of C functions   For more details with regard to command line ordering and processing  please read the getopt 1  manpage using   man 1 getopt

One additional hint  Place the  -P  option after the scp command  no matter whether the machine you are ssh-ing into is the second one  aka destination   Example   scp -P 2222  absolute path source-folder some-file user example com  absolute path destination-folder

I m using different ports then standard and copy files between files like this   scp -P 1234 user  ip address or host name   var www mywebsite dumps    var www myNewPathOnCurrentLocalMachine   This is only for occasional use  if it repeats itself based on a schedule you should use rsync and cron job to do it
