Gents,

I use mpssh or pssh to issue commands to multiple servers. Problem is that some of the commands require pseudo terminal and won't work with these tools.

This will work just fine: "ssh -t user@server command" as stated under SSH man:

-t = Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g., when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty.

So, is there a workaround for the above tools? Or is there any other tool for multi server administration that will work? If you are not sure what I am talking about just try executing "ssh user@server top" and "ssh -t user@server top" to know exactly the difference.

Thanks,
Rod

Hi
I think the package pssh will help you.
Do
which will give the following information:
I don't have some ssh Servers to check it out, but I would do:
Just check it out.

That's not it. Those are different type. Thanks for trying anyway!

Are you talking about this:

http://www.theether.org/pssh/
?
Well then have a look at this:
http://www.theether.org/pssh/docs/0.2.3/pssh-HOWTO.pdf
Page 2 says pssh has the option too.

The "options" are SSH configuration options and not command options like the "-t" to allow pseudo-terminal. So, both parallel ssh implementations will pass the -o option for this (taken from man ssh):

-o option
Can be used to give options in the format used in the configuration file. This is useful for specifying options for which there is no separate command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

Unless pseudo terminal support is one of the options above. The "-t" I need can be found with this information (outside of the "-o" option):

-t Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty.

I never used pssh, but it looks like a plain Python script, in which you can edit the call to ssh in certain lines to add -t. As it's just calling ssh without a full pathname, also an ssh-wrapper could help to customize its behavior.

Thanks for the hint, but I don't want to reinvent the wheel. Besides, my programming skills are very limited. Hopefully soon one of the programmers for mpssh or pssh will implement this.

I even tried cssh but I don't like to open hundreds of little java-like screens on my WS, reason mpssh and pssh are more appealing (script based).

This is a small operation. In pssh it's line 164 and 168 where -t can be addedtoSimilar for line 168. When I read the docs in the right way, it might be necessary to specify -t twice in both cases.

Seems like the version I got does not match your info. I got a later version from here (v2.2): http://linux.softpedia.com/get/Utili...ssh-8542.shtml

Can't locate that line. I edited trying to add the -t but I got a bunch of errors.

Oh, I'm sorry. Do you have this in line 70:then it should be:

Yeah, that's what I tried before. I also tried 'ssh -t' with same results... I get this:

[1] 16:19:35 [FAILURE] LAB-LINUX1 Exited with error code 1

For me it's working with a command like:Is it giving the error only with your application or also with such a simple command?

Edit: you can also try to enter -t twice.

You are officially THE MAN!

My script is working now. I will do some more testing tomorrow but it's looking good! The double '-t' worked:

FROM:
TO:

Well, I am happy with the current results, thanks to you. At least a couple of my scripts are working where they were not before.
