Hi,

I'm running ssh on the trusted system. Is sshd daemon running on your trusted system? If it's not running start sshd daemon. It should be under //sbin/ . Can you also post the sshd_config file settings?

Hello Arockia,

I did not make any changes to the ssh_config file or the sshd_config file.. and the sshd is running...

Hello Deshpande,

The only message I get is ..

Connection to systemname closed.

I use the command ssh -l username systemname

I also tried with openssh 3.1 and had the same problem...:-(

Hi John,

Be sure to use the "-v" option of ssh. You might want to post that output.

Also, ssh from the trusted system to itself. Again, use the "-v" option to see what's going on.

John,
please post the contents of your sshd_config on the server you are trying to connect TO, and the ssh_config from the server you are connecting FROM.

The only thing that running ssh on a trusted system that changes things is if the tcb database is updated or not.

GL,

One thing I really can't under stand is that why is that it is still looking for openssh 3.1 and openssl infact I have already removed this from the system..

Hi again,

Well, your ssh -v output looks like my ssh -v output from a successful connection with the exception of Exit Status 254 which is supposed to be the error code of the remote command. Check out:
http://support2.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000061597111#Q22

It says to add move 'v's to your command for more verbose messages. So try "ssh -vvv ..." to see what happens. You may also want to tweak the sysloging levels for ssh (see the above web page).

HP supports their Secure Shell if you have a support contract.

When I do ssh -V
OpenSSH_3.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090603f

why is that it is showing openssh 3.1 and openssl is it normal ???

Darrell Allen — Thu, 20 Jun 2002 20:47:03 GMT

Hi John,

I don't know if that's normal but it is what I see.

Can you telnet into the system?

The ssh -v output looks fine until the "received eof". I can reproduce simiar output by directing
I think I could reproduce this output by modifying .profile to exit immediately, but that would produce other problems. There are several files that usually run when ssh logs you into the system. If there is a problem with any of these, it could produce output similar to this.

Hope that helps.

There's a difference in capitalization for the -v option. A capital V gives you the version number. A lower case gives you verbose. 2 lower case v's give you more verbose output. 3 lower case v's gives you the most verbose output.
