SSH access to EISNER (DECUServe) has changed

[Hunter Goatley]

The SSH access to EISNER, the DECUServe system, has changed. For
details, please see:

https://eisner.decus.org/online/ssh

For the past year or two, EISNER has also responded to TELNET
connections with a message that TELNET access is no longer supported.
We've also now disabled that message, so TELNET connections are no
longer answered at all.

I have also created a more modern ecdsa host key for SSH on EISNER. The
old RSA host key is still there, but recent releases of Linux will
report that the host key has changed, and you can accept the new key or
continue to override that to use ssh-rsa, as shown on the web page:

https://eisner.decus.org/online/ssh

With the new ecdsa key, you are no longer required to specify
"-oHostKeyAlgorithm=+ssh-rsa" on Linux, etc.

To show you what to expect, here's what I saw when I connected from a
Linux box for the first time and did not specify the rsa key:

hunter@zaius:~$ ssh -p xxxxx goa...@eisner.decus.org
The authenticity of host
'[eisner.decus.org]:xxxxx([148.51.202.51]:xxxxx)' can't be established.
ECDSA key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
This key is not known by any other names
Are you sure you want to continue connecting
(yes/no/[fingerprint])? yes
Warning: Permanently added '[eisner.decus.org]:xxxxx' (ECDSA) to
the list of known hosts.

can you ask Process to port Purveyor to intel OpenVMS? VSI should assist as they really need to offer a webserver that isn't ported from unix
like tomcat. Purveyor is much simpler to use.

Greetings!

What is the invocation for sftp?
TIA!

From OpenVMS:

$ sftp user...@eisner.decuserve.org#22867

Regards,
Volker.

Didn't work. But I found something that did. I'm surprised I didn't try it:

sftp -P 22867 us...@eisner.decuserve.org

Yeah, I went to that site, but couldn't find sftp. No matter. I finally guessed the correct command.

RTFM?

ITS $ help sftp

SFTP
[...]
Options

The SFTP command supports many options, some of which are not
supported on OpenVMS. For a complete list of options, enter the
following command:

$ SFTP -h

ITS $ sftp -h
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]

Revealing where you wanted to use what might have been helpful, too.
Otherwise everyone else must guess, too.

I did. No good. Got the -P, but got the port number wrong. The manual doesn't have the port number. I thought it would be different for ssh and sftp.

Touché'. (Touche', if the diacritical thingie doesn't work.) I should have mentioned I'm working on a Mac. Sorry. "My bad!"

[alanfe...@gmail.com]

Also, who knows what other "options" (or "switches") in that wonderful, lengthy man page I might need? And there are a lot more options on the Mac than are listed above.

alan...@iMac-3 ~ % sftp -h
usage: sftp [-46AaCfNpqrv] [-B buffer_size] [-b batchfile] [-c cipher]
[-D sftp_server_path] [-F ssh_config] [-i identity_file]
[-J destination] [-l limit] [-o ssh_option] [-P port]
[-R num_requests] [-S program] [-s subsystem | sftp_server]
destination
alanfeldman@iMac-3 ~ %

Again, sorry about not indicating my OS.

[Johnny Billquist]

sftp under VMS appears to use # after the host to indicate port.
That won't work on OSX. But checking the man-page:

The destination may be specified either as [user@]host[:path] or
as a URI
in the form sftp://[user@]host[:port][/path].


Notice how you cannot give a port in the first form. -P is your only way
then.

: is usually used to separate host from port in most tools, but since
sftp uses : to separate host from path, there is a conflict on this one.
