change password scripts

Prasad Pati — Fri, 11 Apr 2003 19:01:21 GMT

how can we change password through scripts in hp-ux 11.0. Or any utilities available?

Currently there are no provisions in HPUX that I know of to change a passwd via a script. I have heard though, that you can download something called "expect" that will simulate an interactive session.

Good luck

I hope we can achieve this by Perl if we can delay, like we used to do in Perl telnet module. I am not sure, but I'll certainly spend time on it and let you know.

Thanks

Yes, 'expect' has some features that claim to support this.

http://expect.nist.gov

is where you can find expect.

http://expect.nist.gov/example/autopasswd

shows an example.

here is a sample script using expect.

u can get expect from here

http://hpux.connect.org.uk/hppd/hpux/Tcl/expect-5.38/

+++++++++++++++++++++++++
[balajin@redpenguin X11]$ more /usr/bin/autopasswd
#!/usr/bin/expect -f
# wrapper to make passwd(1) be non-interactive
# username is passed as 1st arg, passwd as 2nd

set password [lindex $argv 1]
spawn passwd [lindex $argv 0]
expect "password:"
send "$password\r"
expect "password:"
send "$password\r"
expect eof

First you need to change the password in one system only, and then use a script to copy this password to the other systems, this is possible even if you are using a trusted system.

Scripts are the less than optimal method. You would be far better served by implementing NIS (or better NIS+) and manage your passwords in one place.

yes you could do this with expect. I'll attach a sample script for you. basically once installed you would type:
autoexpect -f telnet hostname
#where filename is insert the name you want to save your script to. Then proceed to use the passwd command to change your password.

you will need to edit your script then to remove things such as the date/time otherwise the script will not work.

Are you looking to change 1 password or are you looking to maybe do a mass password change? changing a group of identifiable users to a new/same password?

Just asking,
Rita
