File copy over DECnet.

[Noor Ahmed_1]

Hi managers,

I am encountering a problem in file copying over DEcnet form one node to other.
One node is on DECnet PaseIV on OpenVMS Alpha V6.2, other node is on DECnet Plus on itanium server running OpenVMS V8.2. I have registered DECnet PaseIV node adrress in DECnet Plus Node, and I can set host to nodes, but when I copy file from One node to another I have to mention Username and passwords in command line. How can I avoid user name and password in command line??How can the nodes be made trusted???

example of command is:

$copy node1 "username password"::[Disk]filename []

Ahmed,

The are two ways to do away with the username and password requirements, and they are complementary. They are logical names and proxy access.

If you create a logical name, which specifies the nodename, username, and password of the other machine, then your use of the logical name will completely eliminate the need to manually enter the node, user, and password on each access. However, it will expose the password if the logical name is displayed (RMS is smart enough, when displaying the directory name and error messages, to use the string "password" instead of the actual password, but the SHOW LOGICAL command cannot make the presumption).

You can eliminate the password entry on each access using Proxy Logins. They are fully described in the DECnet manuals. If you do not have the hardcopy for the DECnet manuals, you can get it online via the OpenVMS www site at http://www.hp.com/go/openvms.

These are, as I mentioned earlier, complementatary. Both can be used. The logical name eliminates the need to specify the nodename, and the proxy eliminates the need to specify the password on each access.

I will also mention, as a side note, that this would not happen were the machines clustered, since a clustered system is a single security domain, disks generally are organized to be cluster mounted, so a simple file copy, without node name or network semantics, can be used.

Ahmed,

You need to set up proxy access to be able to do
the copies without specifying password.

On the Alpha:

$ mcr authorize add/proxy itanium::username localusername

On the Itanium:

$ mcr authorize add/proxy alpha::username localusername

filling in the appropriate nodenames and usernames.
You can also add /DEFAULT to remove the need for
specifying the username on commands. Personally
I don't use /DEFAULT and thus always specify
usernames on my commands.

I'm with Dave but I prefer /DEFAULT option.
Usually I create same user on both machines so with /default option user can access on other side declaring only nodename.
It's just a my preference.
