HelpDesk Script

Charles Keyser — Wed, 10 Mar 2010 17:56:34 GMT

I have a helpdesk script (see Below). When I run the script as root ./Helpdesk it will bring up the screen I can select option 4 enter the users name and change the password

When I log in as HelpDesk enter their password it will bring up the screen I select option 4 and here is the message I receive. ANy ideas what I am missing? Thanks

Apparently the script uses the sudo command, which is an add-on product not directly supplied by HP. It needs to be in the user's path or the full path name of the sudo command should be specified in the script.

What would be t he easiest way to resolve this? Our new help desk will be using the script and when the log in I would like for them to be able to reset and redo their password. Any help is appreciated

Re: HelpDesk Script

Pete Randall — Wed, 10 Mar 2010 18:14:36 GMT

The easiest way would be to change the script. Check to see where sudo is installed (probably /usr/local/bin) by doing "whence sudo". That should find it if run by root. Then edit the script itself and change all occurences of "sudo" to "/usr/local/bin/sudo".

You could also fix their PATH environment variable but that gets a bit more involved.

Hi

Regarding the easy way, well, this is a build team or install team or a production team issue. Sudo can be easily installed during first build. It can easily be installed over the network now. Refer to your O/S version and the intenet express bundle for 11.23 and 11.31.

11.23 link

https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=HPUXIEXP1123

Sounds like its a project that you'll have to get approval on. A good way to start the ball rolling would be to id the servers needing the install. Do you have access to all?

Re: HelpDesk Script

Charles Keyser — Wed, 10 Mar 2010 18:23:47 GMT

Would this be the correct way?
#This command looks at the account if it has a password liftime expired it will reset the account and enable it
#sudo /usr/lbin/modprpw -x ${USER}
/usr/local/bin/sudo

I am not an expert at writing scripts

Re: HelpDesk Script

Michael Steele_2 — Wed, 10 Mar 2010 18:26:22 GMT

Oh. I didn't read this as a PATH environment variable update. Well, this is easier but still probably a project needing approvals as I doubt the PATH env var will be identical on every box. So you should build a script to append the PATH var.

export PATH=$PATH:/usr/local/bin/sudo

Test out the above to see if it's what you want.

Re: HelpDesk Script

Charles Keyser — Wed, 10 Mar 2010 18:26:53 GMT

I would not be able to do any upgrade, the servers are running applications that if an upgrade was done the applications would not work. I have asked in the past and it was shot down

Re: HelpDesk Script

Charles Keyser — Wed, 10 Mar 2010 18:33:39 GMT

I am not sure where you are asking me to input the export Path?
Would it be in the HelpDesk log in or profile or in the script
If in the script where?
sorry again I am trying to understand this and learn with your assistance
Thanks

Re: HelpDesk Script

Pete Randall — Wed, 10 Mar 2010 18:43:35 GMT

Charles,

The reason I suggested changing the script rather than changing the path is because you first have to figure out how and where the path is being set. You could append a "export PATH=$PATH:/usr/local/bin" statement to the users login profile, but that's going to depend on which shell they are using and how they are logging in.

Edit the helpdesk script and change "sudo" to "/usr/local/bin/sudo".

Charles Keyser — Wed, 10 Mar 2010 18:54:34 GMT

I commented this out
#sudo /usr/lbin/modprpw -x ${USER}

Added
/usr/local/bin/sudo /usr/lbin/modprpw -x ${USER}

And it worked just fine. Thanks for all of yor help

As you become more experienced in Sysadmin work, one of the habits you should acquire is to always use full path names in your scripts and make sure all your environment variables are defined.

Whoever wrote this script (I'm assuming it wasn't you) should scold herself!

Rita C Workman — Wed, 10 Mar 2010 19:10:09 GMT

Once you have the correct path for where sudo is installed, put it in the line where sudo is used that you mentioned earlier (in your case 4 stmt...)

...and whoever edited my script needs to go back and fix it; cause he menu is off from commands. If you're gonna change it - do it right.

Kindest regards,
Rita

Re: HelpDesk Script

Charles Keyser — Wed, 10 Mar 2010 19:14:12 GMT

Sorry, I am just trying to fix what is there. I did not mean to offend or make anyone angry. The script is awesome and will work for us to do what we need. My apologies

-Charlie

Re: HelpDesk Script

Rita C Workman — Wed, 10 Mar 2010 19:21:36 GMT

Offend....it didn't come out right....I am totally flattered!

Maybe one day I'll share the one I wrote to cleanup some logfiles on Itanium boxes, cause they took out SAM and that quickie logfiles cleanup utility.

Kindest regards,
Rita

Re: HelpDesk Script

Charles Keyser — Wed, 10 Mar 2010 19:28:18 GMT

Thanks Rita. I appreciate that. The script keeps me from being woke up in the early AM where the Help Desk folks can log in run the script get the password and send the folks on their merry way.

Again Thank you

I didn't use sudo............

ha ha....

Re: HelpDesk Script

Rita C Workman — Wed, 10 Mar 2010 20:44:01 GMT

OK.............hope this helps you a little. It's still looking for the path for sudo you need to enter.

Regards,
Rita
