Password Changer and rexec help
|
|
| Nandkishore.Sagi 2004-04-21, 1:35 pm |
| Hi All,
I am looking for some module which would help me in changing the
password on multiple boxes.I have the same login ID and would liketo
change the password for all of them using a Perl script.
Also I am looking for a perl module which can help me to logon
onto different boxes and execute a given script .Something more like
rexec.
Thanks a lot for your help.
Thanks and Regards

Yikes, if you are going to go that route then consider Net::SSH::Perl,
has worked well for me in the past, once you get through the dependency
installation.

Good idea, flame-suit. I am familar (meaning I have used it enough to
have gotten serious headaches from it) with expect, yikes. :-) Expect
for me is a next to last resort. Just too many things that can go wrong
and probably will.

Expect isn't a language, it is a program written in Tcl.

You may want to look at the Perl Expect module. It has similar
functionality as expect, but is IMHO a bit more rational.
BTW, expect is not written in Tcl. It uses Tcl syntax for flow control,
but it is a separate language. The Unix version is written in C as is
Tcl.

From John Ousterhout at http://www.tcl.tk/doc/tclHistory.html
<QUOTE>
One of the people at the USENIX presentation was Don Libes of the
National Institute of Standards and Technology. Don had been wanting for
some time to build a program to automate interactive Unix applications,
but the project had stalled because it needed a good command language
and Don didn't have the time to build one. After hearing my talk, Don
rushed home, downloaded Tcl, built a wonderful application called
Expect, and wrote a paper on it in time for the submission deadline for
the next USENIX Conference. This whole process took just three w s.
Don made Expect freely available after presenting his paper in the
summer of 1990, and it became an instant hit among system
administrators. Expect was not only the first widely distributed Tcl
application, but for many years it was the most popular. Many of the
early Tcl users learned about it by using Expect.

I wonder, had something similar happened to Larry in early Perl days
would Larry have stopped working on Perl -- Don Libes has more or less
stopped working on Expect.
Semantics of what is a language and what is not I will avoid.

Thanks! Interesting bit of history I did not know. I am speculating Don
reimplemented expect in C for efficiency. It is an interesting build
process, since you do need the Tcl libraries to build the expect binary
on Unix systems. I went thru that process around 1992 when I first
discovered expect.
