SSH/SCP problem in HP-UX 11.23 PA

[shashi kanth]

My target machine is running SSH.

OpenSSH_4.3p2-hpn, OpenSSL 0.9.7i 14 Oct 2005
HP-UX Secure Shell-A.04.30.007, HP-UX Secure Shell version


I can able to SSH to this box.

But "ssh date" gives no ouput.

"scp :
But all i can say is, i am using bash shell, i don't use /bin/sh .

with /bin/sh, there is no problem.

The problem is because of using bash shell.

i have installed bash shell which is given by HP itself .

Anyone tell me , what step i have to take with bash shell so that this problem own't appear ?

Shalom,

You have identified the problem yourself.

You are using the bash shell. By default, when you ssh to another server the environment is limited. Therefore you ssh command will provably provide output if you provide the command as follows:

ssh /usr/bin/date

Clearly HP's ssh/scp implementation was not designed to work with the bash shell.

If you however provide environment, either by building it into a script or changing the .bashrc or .bash_profile you may get it to work anyway.

"ssh /usr/bin/date" also own't work.

Dennis Handly, the URL that you have given, i am not finding any help in that.

I can't live without bash shell. Without bash shell, i can't work with any Unix/Linux box.

Please anyone tell me, how to solve this issue ?

Hi,

Could you add the -v option for dubbuging?

scp -v :

It doesn't help much.

>i can't work with any Unix/Linux box.

I feel the same way about ksh/sh. :-)

I suppose you could change your login shell to a real shell, sh, then invoke bash to do your work.

I assume your problem isn't as simple as not having bash in /etc/shells?? shells(4)

Are there some machines where scp works? Can you use scp to your own machine?

(1)scp from Linux to HP-Ux works

(2)scp from HP-Ux to Linux works

(3)scp from HP-Ux to HP-Ux don't work.
