a small bug is discovered
10/11/2006
Jeff from Indiana has written in to notify us of the following bug:
We're using PUSSH here at work and liking it very much.
We need to be able to send echo commands containing square bracket
characters. It seems that no matter how we try it we get the error
"PUSSH(001): Invalid host targetting - do try try again."
It thinks we mean to delimit a range of hosts with the brackets, when we
really aren't. Even putting the command in quotes won't work:
pussh -f hostlist -r "echo some[string" ...
What can we do?
Thanks for this bug report Jeff. We confirm the bug exists, and that we're working on
correcting it in the next version.
pussh_1.05 out today
24/06/2005
A support ticket from last week highlighted a lack of support for different SSH protocols.
This problem should be resolved in todays release. In future, PuSSH should support any and
all SSH client options, but for now, thanks for bringing issues such as this to our attention.
new release out now with cleaned up code - 1.04
14/06/2005
You can now go directly to the official sourceforge project page to
download this latest
cleaned up PuSSH, rather than to the temporary link posted in the previous update. This is
better for the project statistics, and also the right way to do things.
PuSSH works on AIX!
20/01/2005
Realistically speaking, there was never any reason why it shouldn't. As long as Python is
installed (in this case python-2.2-4, on AIX5.2), we seem to be in business. In other news,
thanks to the testers at iverve.com, it was discovered that the current release on SF is
buggy. The core functionality is there, but the '-f <filename>' option, doesn't work,
among other possible options. Due to a certain lack of time, a decent testing environment and
other unfavorable circumstances, a 'bum version' got released. Before a newer, fully working
version is released on SF however, you can get an older, stable version here instead. Remember to change your paths
if you need to, to specify the directory you want to run PuSSH from, in the pussh script
itself, at lines 88/89, otherwise just dump everything into a /home/yourhomedirectory/pussh
directory. Everything else you need to know is in the INSTALL.txt.
PuSSH appears on Python-Eggs.Org
15/06/2004
Fame at last! There's a fair buzz in the Python community about this eggs site. I
certainly like it, even if it is just a great collection of links.
first honest impressions, after intensive stress testing
29/10/2003
apart from non-existent targets (as opposed to
existing, and receptive targets i.e. those on
which sshd is running and which execute the PuSSHed command)
causing a slightly heavier load on the source machine
than some people might expect if commands are executed in
parallel on too many such machines (the results of fairly intensive benchmarking
in an environment of hundreds of machines of which
75% to 95% are "valid targets" would suggest a maximum
"parallel slice" of 40-50 target machines if
you don't want to see a load higher than about
3 on the machine from which the PuSSHed command
originates, and we have accounted for this in the
latest version - the default parallel slice parameter
is a fine-tuned 42, but otherwise you can fairly
safely go to about 100, or even beyond, although this
obviously depends on what else you have going on), the
fact that no serious
bug reports have appeared thus far has prompted
a development status upgrade to "production/stable",
although we are retaining the beta status as well
and concurrently, unusual as this may seem (basically,
circumstances would indicate PuSSH could technically speaking
still fall under either status umbrella by definition, so
why not have both?). In other news, DS Libby has
officially joined the PuSSH team, as his input
has been invaluable not only during most of the
development life-cycle thus far, but he will also
be implementing some test-scenarios shortly, with
a view towards verifying and expanding the flexibility
of PuSSH per se in environments where SSH could
be configured differently from how it was on the
original development platform (CERN PDP clusters,
using Kerberos authentication).
next to no bugs in the production environment
- alpha turns to beta
10/09/2003
Because PuSSH doesn't seem to show any actual
bugs as such after initial testing in the
CERN production environment,
yesterdays alpha release has been upgraded to
a beta release (as discussed unofficially). The
only significant changes to the package inbetween
are the addition of an INSTALL.txt file, and the
modification of the path to brussh.py to reflect
the installation instructions.
a Python success story is written.
09/09/2003
The first ever alpha release of PuSSH goes global
on Sourceforge - as far as anyone can tell, and
as basic as the idea may seem at first, at least
possibly to a somewhat a more advanced Python
developer, this is the first time this kind of
application has ever been attempted in Python.
At present, "the construct" consists
of 2 separate Python modules (one calls the other
directly), both of which are now available in a .tgz.
It works on most if not all Linux distros for sure, and
is probably completely platform independent.
On linux/unix, after downloading to your home directory,
run tar -zxpf on it, and then simply run it from its own
directory thereafter i.e.
[$] ~homedir/pussh/pussh --help |
