scripts

Hi

Let me know any body is having the following scripts.

1. script to check for the .rhosts file and housts.equiv files in system, if .rhosts exists send it to trash and if housts.equiv exists make sure it is empty.

2. script to check whether the applications is up or not
is not mail to administrator.

venkatmk, I always find it's a good idea to do a bit of research if you're unsure how to do something. It makes learning more worthwhile, and in my opinion, makes it stay in your head!. As a first point of call, have look at the following man pages on your system ...

man test - this explains how to check for the existence of files, directories, empty files, etc.

man ps - explains how to check for running processes

man grep - allows you to search for a specific string in the input ...

so you could use ps andgrep together to check for a running application, and if you find it, use the mail command.

Hope this sets you on your way. If, after this, you have any other queries, post again and we'll be happy to help.

Greg.

i've come across a good way of stopping .rhosts ...

as root create a .rhosts file in the users home, and set it so that noone can write to it, and _definately_ set the user to root:sys ... and that way they can _never_ put anything in those files, so no need to check.
