Hi,
Suppose I am user1 and I want to call a script using user2 (i.e., as if I call it while I am user2). However, I want to specify user2 password progromatically (without requiring user1 to enter it). Is this possible?
Thank you in advance
Best Regards

Check out expect, located at:expect.nist.gov .

These can be possibilities

1)set 'Set user-id' bit to user2 script.So that when u run user2.scr
while login as user1 still it runs as if user2 is executing it.

I am not sure whether it creates file etc where user1 has no permission..

for e.g. chmod 4755 user2.scr

2)Dynamically create .netrc file and rexec the user2 script


GOOD LUCK

Thank you very much

I didn't think you can use SUID for a shell script?

I believe that you can setup "sudo" privledges for the other user. Here are a few posts that may help.

For years that was true because suid shell scripts opened up a security hole that could not be closed. But now some unix versions have a /dev/fd psuedo filesystem which enables this hole to be closed. Recent SunOS versions fall into this category and they support suid shell scripts.

It surprised me too.

How abt trying to add an entry in /etc/inetd.conf for the script to be invoked under user2, and Start a program from user1 which will make an inetd connection to the inetd port of user2's script entry. You dont need the user2's passwd in this case.
