sftp on openvms

Bill Stewart_4 — Thu, 22 Dec 2005 14:45:11 GMT

Could someone please post an example of using sftp in batch mode on openvms.

we are running
HP TCP/IP Services for OpenVMS Alpha Version V5.4 - ECO 5
on a AlphaServer 1200 5/400 4MB running OpenVMS V7.3-2

Bill,

try this...

$ sftp -bbatch_file username@host

try this also
$sftp -bbatch_file 'usrname':'psswrd'@'node'

Bill,

this is SFTP cmnd Synopsis, you can give the necessary options if you know.

$ SFTP [-D ] [-b batchfile] [-S path][-h][-v] [-P ssh-port] user@host

-D debug-level Displays debug information. The debug-level value is a number between 0
and 99

-b batchfile Reads commands from a file instead of from SYS$INPUT.

-S ssh-path Specifies an alternate location for the SSH server executable file.

-h Displays information about how to use the SFTP utility.

-V Displays the version of SSH.

-P Tells SFTP on which port the SSH server is listening.

You will probably have to set up public key or host based authentication for batch mode to work.

Bill,

using SFTP from batch mode requires more than just knowing how to specify the options for the SFTP command...

I've found the following manual to best provide the necessary pieces of information:

http://h71000.www7.hp.com/openvms/products/ssh/ssh.pdf

I've followed the different chapters in this manual and have successfully set up the environment to run SFTP from a DCL procedure interactively (no prompt for password) with using user-based public key authentication.

For BATCH mode, host based authentication seems to be necessary, as you can't run an SSH_AGENT in batch mode. The SSH_AGENT is required to ask for and store the passphrase for the user's key file(s).

Once I'll get this running, I'll provide and describe the necessary steps (for TCPIP V5.5). There's a long weekend ahead, isn't it ;-)

Volker.

Bill,

it works well with TCPIP V5.5. I've done the setup based on the 'HP TCP/IP Services for OpenVMS Guide to SSH (TCPIP V5.4)' manual referenced above.

Here are my notes from the setup and an example BATCH procedure and logfile:

Setting up HOSTBASED Authentication
===================================

On SSH Client:

in TCPIP$SSH_DEVICE:[TCPIP$SSH.ssh2]SSH2_CONFIG.

DefaultDomain domain.name ! make sure to enter full domain name of local node

On SSH Server:

TCPIP$SSH_DEVICE:SSHD2_CONFIG.

AllowedAuthentications hostbased, publickey, password

TCPIP$SSH_DEVICE:SHOSTS.EQUIV

fully-qualified-client-IP-name username

NOTE: use lowercase username for OpenVMS clients

Copy from SSH Client

TCPIP$SSH_DEVICE:[TCPIP$SSH.ssh2]hostkey.pub

to SSH Server

TCPIP$SSH_DEVICE:[TCPIP$SSH.ssh2.KNOWNHOSTS]fully_qualified_client_SSH-DSS.PUB

e.g. NODE_DOMAIN_NAME_SSH-DSS.PUB (for client node node.domain.name)

Using SFTP from BATCH mode
==========================

Use TCPIP V5.4 ECO 5 or TCPIP V5.5

$ sftp "-B" "/userdisk1/halle/itrc/bf.ftp" hostname

Batchfile USERDISK1:[HALLE.ITRC]BF.FTP:

ls login.com[lf]
cd [.itrc][lf]
get x.x[lf]

NOTE: [lf] = each line needs to be terminated by [LF] character = ASCII 10.
In TPU: [GOLD]10[GOLD][SPEC INS]
or the file needs to be converted to STREAMLF record format

NOTE: Files to be copied etc. by SFTP need to be in STREAMLF format:
$ set file/attr=rfm:stmlf x.x

Batch logfile:

$ sftp "-B" "/userdisk1/halle/itrc/bf.ftp" hostname
sftp> ls login.com
login.com

/userdisk1/halle/itrc

x.x | 0 kB | 0.0 kB/s | TOC: 00:00:01 | 100%

Merry Christmas and a Happy New Year,

Volker.

Re: sftp on openvms

Volker Halle — Tue, 12 Feb 2008 17:52:06 GMT

Correction:

...

On SSH Server:

TCPIP$SSH_DEVICE:[TCPIP$SSH.SSH2]SSHD2_CONFIG.

AllowedAuthentications hostbased, publickey, password

TCPIP$SSH_DEVICE:[TCPIP$SSH.SSH2]SHOSTS.EQUIV

fully-qualified-client-IP-name username

NOTE: use lowercase username for OpenVMS clients

Hi All,

I need to connect to an IP through SFTP from VMS. I have the user name password and the IP. I need to find out whether the file is present or not.
I tried like this

sftp user_name@host password

But it throwed the below error:
Too many arguments.
Usage: sftp2 [-D debug_level_spec] [-B batchfile] [-S path] [-h]
[-V] [-P port] [-b buffer_size]
[-4] [-6] "[-C]" [-o option_to_ssh2]
[user@]host[#port]

Please Help me out.

Re: sftp on openvms

Joseph Huber_1 — Thu, 30 Sep 2010 13:39:36 GMT

The clear text error tells You "Too many arguments".
There is no such argument "password" on the sftp command-line, only user@host.
When sftp starts, it will prompt for the password , unless You have a public key established.

Although my version is older, it gets a "usage" response only if the command-line is really wrong.
And in Your case it gets an error as soon as You have a user@host argument.
My suspicion still is: You have a DCL symbol "sftp" defined,
what does "SHOW SYMBOL SFTP" return ?

Have you tried installing a newer TCPIP ECO?

Re: sftp on openvms

Joseph Huber_1 — Mon, 04 Oct 2010 12:23:52 GMT

Well mine seems to behave much different,
especially to automatically connect to the local host if asking the version in
sftp -v , which actually is "sftp -V".
Hope somebody with the combination VMS8.3/TCPIP 5.6 can reproduce something like that.

Meanwhile use debugging/verify:

sftp -"v" user@host !observe the string quotes!

to see more disgnostic revealing the point at which the error occurs.

Re: sftp on openvms

Hoff — Mon, 04 Oct 2010 15:12:32 GMT

CHANDRASEKARAN S:

In no particular order...

Ensure that the ssh client and ssh server are appropriately started via TCPIP$CONFIG.COM

Failure to start the appropriate client and server components has an unfortunate and long history of tossing obscure errors.

Patch to current; V5.6 ECO 2 is old.

Ensure the process quotas and process environment are sufficient. Details on minimum quotas should be in the manual, and you'll likely need TMPMBX and NETMBX minimally.

Test connections into the target server from another box. See if this is local or a server error.

Remove any DECC* logical names that might be around in the process or job context. Sufficiently odd settings for these can trigger errors in most any C application.

And I'm seeing completely different "usage" diagnostics with V5.6 ECO 5, so definitely roll forward to ECO 5.

Steven Schweda — Mon, 04 Oct 2010 17:42:10 GMT

> sftp -"v" user@host !observe the string quotes!

Quoting "-v" is not required. Quoting "-V"
probably _is_ required. (As shown above.)

Joseph Huber_1 — Tue, 05 Oct 2010 05:53:12 GMT

>> Quoting "-v" is not required. Quoting "-V"

So I keep quiet. Seems there are so many changes between TCPIP 5.4 and 5.6.
On my 5.4 sftp is a DCL verb, and both unquoted -V and -v result in "show version".
Only -"v" results in the desired "verbose".

It would be nice to see the output from

$ sftp "-V"
