SSH on VMS 7.3-2

robert70 — Fri, 05 Dec 2008 14:21:06 GMT

I have started up SSH on VMS 7.3-2
Trying to connect with a telnet/ssh
where on the Alpha side can I find the public and private key information to enable me to connect?
thanks

there are two files that should be in an ssh2 sub directory for your username , an identification file and an authorization file

identification file contains details of your private key

e.g

idkey priv_key_name

authorization file contains public key details

e.g

key public

use the tcpip$ssh_keygen.exe to create a private/public key pair.
certainly putty generated public keys can be used without issue and should be in the same ssh2 sub directory.
all 3 methods hostbased/public key and password can be enabled/disabled in the ssh conf files for client and server in the tcpip$ssh directory.

also obviously see the tcpip guide to ssh on the hp site

good luck

From what? To what? Do you already have
keys somewhere? (Where?)

Yup. Need directions?

Some reading:

http://64.223.189.234/node/1118

But do start with the HP manual for ssh. ssh starts out a little weird, and the HP OpenVMS port layers another helping or two of weirdness into the baseline ssh weird.

steven,

the link to the hp vms manuals is on the forum web page you don't need directions to get where you're already at :-)

While the following was clearly intended as a joke:

>the link to the hp vms manuals is on the forum web page you don't need directions to get where you're already at :-)

I can assure you that such is *not* a universal finding.

Further, the sheer scale and relative lack of indexing of the existing resources (manuals, help, the HP web site, the stuff in or disappeared from the support databases) is an increasing problem for inexperienced users. (I *know* where this stuff is and I've read much of it over the years and I've written some of it, and it can sometimes take me a while to find a reference.)

my keys dont get made when i select enable and start service on node (ssh)
any help?

SSH configuration options:

1 - Enable service on this node

2 - Enable & Start service on this node

[E] - Exit SSH configuration

Enter configuration option: 2

the service is enabled but never started and there are no PUB keys in the directory?

Re: SSH on VMS 7.3-2

Steven Schweda — Thu, 11 Dec 2008 14:48:20 GMT

alp $ sysmsg %x0764CFBC

%TCPIP-F-SSH_FATAL, non-specific fatal error condition

Not very informative, I'd say.

> [...] there are no PUB keys in the

You're SYSTEM when you do this stuff? Do the
directory protections and owner look
reasonable? I haven't made any host keys in
a while, but around here:

ALP $ dire /owne /prot /size TCPIP$SSH_DEVICE:[TCPIP$SSH.SSH2]host*

Directory SYS$SYSDEVICE:[TCPIP$SSH.SSH2]

HOSTKEY.;1 2 [TCPIP$AUX,TCPIP$SSH] (RWD,RWD,,)
HOSTKEY.PUB;1 2 [TCPIP$AUX,TCPIP$SSH] (RWD,RWD,R,R)
HOSTKEYS.DIR;1 1 [TCPIP$AUX,TCPIP$SSH] (RWE,RWE,RE,E)

Total of 3 files, 5 blocks.

You might try moving/removing the whole mess,
and starting fresh. Otherwise, I'd probably
start dissecting TCPIP$CONFIG.COM to see
what it's trying to do when it goes bad.

i am running this under SYSTEM yes.
the directory is TCPIP$SSH_DEVICE:[TCPIP$SSH.SSH2]but as i say the HOSTKEY.PUB is not created because of that error message.

Robert,

a possible cause of this issue is that the SYSTEM account is not associated with the SYSTEM identifier in SYSUAF.

Observe key generation when account and identifier match:

DEVT02> ssh_keygen "-P" fred
Generating 2048-bit dsa key pair
5 oOo..oOo.oOo
Key generated.
2048-bit dsa, morrisd@devt02.cpwplc.net, Thu Dec 11 2008 15:15:21
Private key saved to fred
Public key saved to fred.pub

Then modify my identifier in SYSUAF/RIGHTSLIST

DEVT02> mc authorize
UAF> ren/id morrisd fffred
%UAF-I-RDBMDFYMSG, identifier MORRISD modified
UAF> Exit

and retry key generation...

DEVT02> ssh_keygen "-P" fred

Error: Could not get user's password structure.
%TCPIP-E-SSH_ERROR, non-specific error condition
DEVT02>

Check your SYSUAF entry for SYSTEM!!!

Duncan,

doing a show system on uaf :-

Username: SYSTEM Owner: SYSTEM MANAGER
Account: SYSTEM UIC: [1,4] ([1,4])
CLI: DCL Tables: DCLTABLES
Default: SYS$SYSROOT:[SYSMGR]
LGICMD: LOGIN.COM

is this as should be?

Re: SSH on VMS 7.3-2

Duncan Morris — Thu, 11 Dec 2008 15:40:18 GMT

No - there is no identifier for SYSTEM, so you are seeing [1,4]

Here is a sample with an idenitifier

UAF> sh system

Username: SYSTEM Owner: SYSTEM MANAGER
Account: SYSTEM UIC: [1,4] ([ISE,SYSTEM])

Check if the identifier SYSTEM exists

UAF> show/id system
Name Value Attributes
SYSTEM [000001,000004]
UAF>

If not, then

UAF> ADD/ID/USER=SYSTEM

and AUTHORIZE will create the identifier for the account.

If it does exist but with another UIC, then you need to question why some other account has this identifier!

Re: SSH on VMS 7.3-2

robert70 — Thu, 11 Dec 2008 15:55:07 GMT

that was the problem Duncan !!!!
added the rights 1,4 to system via uaf
able to create public key and connect now
many thanks

Hi Duncan,
that was strange, I was running from a copy of the system account and got the accvio errors. When I run from the system account the keys are generated as expected, and I can run ssh2 -v localhost. But there is some kind of problem with the keys, look at this,
(unable to open...)

The file is readable, and the system account have bypass so it shouldn't be a prot problem. My system disk is at ODS-5, do you know if that could cause anything ?
