[Pyssh-discuss] problem with pyssh

[Michele S. <mi...@pi...>]

I  have successfully installed pyssh on my machine (Red Hat Linux 7.2).
However when I try to use it, nothing happens.
This is what I have:

python pyssh.py host=tycho.lpthe.jussieu.fr user=micheles command=date
password=******* debug=1
>> child says: "mic...@ty...'s password: "
>> child took 8 password bytes
>> sleeping 0 secs
>> child took 5 command bytes
>> child response is '\r\ndate\r\n'
results =
'\r\ndate\r\n'

I would expect a string with the date instead !

Any suggestion ?
Second question: how can I scp a file ??

thanks,

AW: [Pyssh-discuss] problem with pyssh

As previously pointed out, pyssh seems to have some difficulties. It
works perfectly and the command should be executed (one may check that),
but the output can' t be fetched due to some inconsistancy. It seems to
be important to read every output (eg also the entered login). I have
neither had the time nor the passion :) - to provide pyssh with a patch
for that, since even the developer himself doesn' t use it. :)

Attached to this mail you find some code which should work in place of
pyssh. It is something I recently did for a project at university. I
grabed the files from a package (another context) - so names may look a
bit confusing - but it should work. You' re free to use it in any way
you want.

python pyssh.py host=3Dtycho.lpthe.jussieu.fr user=3Dmicheles =
command=3Ddate
password=3D******* debug=3D1=20
>> child says: "mic...@ty...'s password: "=20
>> child took 8 password bytes=20
>> sleeping 0 secs=20
>> child took 5 command bytes=20
>> child response is '\r\ndate\r\n'=20
results =3D=20
'\r\ndate\r\n'=20

Well, I can't use it if it doesn't work. :)

I've never been able to get the interactive input of passwords and 
commands, and output of the commands to work consistently...

OK. So here is the patch for pyssh. At least it works for me :) - The
trick is to insert another os.read() that fetches the banner (everything
between password-prompt and system-prompt). I am not quite sure how this
will react on empty banners (read "\r\n" or raise error), so it may be
reasonable to implement those os.read() as select.select() - calls as I
did.

I thought it would only be consequent if one had to read the
system-prompt before issuing a command. However this doesn' t seem to be
necessary. If this differs on some platform - you now know what the
cause is. I'd be happy to hear whether this thing works or not.

Greets,

Julian
