You'll get twice the network traffic since the copy is running on
your workstation (or whatever).

I normally use ssh to log into a remote server, change
directory and then use scp from there to copy files from
another remote server to the first one.
Now the first server has been hit by continuous error
correction messages from the ECC controller, all of which are
corrected, and I am unable to get a command line to issue the
required commands to change directory and then run scp from
the other server. I have no problems, however, getting into
the first server - except for being drowned by the error
correction messages and the server seems to be running
"fine".
Until I am able to get to the server and investigate, is it
possible to accomplish the above on a single command line,
thus avoiding seeing the error messages? I should add that
both the first and second server are set up to accept keys
and not passwords so at least I don't have to worry about
that.
Thank you. _______________________________________________

This did not work even though the same user is authenticated on
both servers and I have no problems ssh'ing into either of the two
servers. The message is "permission denied."
Presumably some problem with being recognized on both systems?

It sounds like it. Try:
$ ssh svr1 pwd
$ ssh svr2 pwd
If they work without asking for a password then there is a deeper
configuration issue. If you do get prompted for a password then you
need to sort out your access. If the username differs try
<user>@<host> both for the ssh test and the scp command.

I don't know. I have no problems with 'ssh user1@server1' and 'ssh user1@server2' or running 'scp user1@server2:somefilesserver2 tolocationonserver1' after having ssh'ed into server 1.
I just tried 'ssh user1@server1 'scp user1@server2:somefilesserver2 tolocationonserver1'' which worked fine suggesting that the configuration is correct.
There seems to be something broken when using scp between two remote locations. Some posts on the 'net suggest using 'scp -3' to do an intermediate copy to the workstation between the two remote servers but that option does not seem to have been implemented yet on scp for Centos 6.7.
