Re: how to hide passwd while copy between server.
1) set nover before the copy and the password will not show in log files
2) put password in symbol and use "account ''symbol'":: in the command procedure.

Re: how to hide passwd while copy between server.
But....
Instead of passing username and password, you can setup a proxy in node2 for the specific user.
$ MCR AUTHORIZE
UAF> ADD/PROXY remodenode::remote_user local_user /DEFAULT
$ MCR AUTHORIZE HELP ADD/PROXY ( for additional help )

Re: how to hide passwd while copy between server.
There is hiding and there is hiding.
DECnet is unencrypted (unless you are using DECnet over IP, and that over an enciphered channel, either directly or using a tunnel such as SSL).
To prevent the password from showing, one can use a logical name, to wit:
$ assign
$ directory remote_node:
The output of DIRECTORY will now not show the command. Of course, a SHOW LOGICAL command will display the logical name (as will ANALYZE/SYSTEM). For this type of purpose, it is worthwhile to make logical name user mode. However, the password WILL be in the clear on the network.
Using a Proxy, as has been suggested, requires trust between the two machines, which is a whole other hazard.
Perhaps it would be helpful to clarify from whom we are securing the password and for what purpose.

Re: how to hide passwd while copy between server.
You're using classic text-based passwords and DECnet, so you're already somewhere between comparatively and completely insecure. You could use DECnet proxies and such here, but that's not particularly secure.
Switch to sftp and public key encryption, if you're serious.

Re: how to hide passwd while copy between server.
Where are those apostrophes?
node2"account ''tt'":: ?
To avoid confusion with the logical name
"TT", I'd avoid using a symbol "tt".

Re: how to hide passwd while copy between server.
My post from yesterday has a typographical error.
The ASSIGN command should read:
$ ASSIGN/USER_MODE "
The
My apologies if the typographical errors caused any difficulty.
