Shell Programming and Scripting

hi,

well , if i say i can't ask , that's all i will not ask.

..... sorry i don't understand what you say "vbe" !

I agree with corona here, if your IT team has like we have aplliances that are after clear passwds on your intranet, you will be in the dog house...
Your only alternative will be since you have the passwd on both system to go for a passwdless connection by exchanging your public keys...

previous: I mean you will be asked twice the passwd how do you bypass that?

It may be possible to reduce the number of ssh calls quite a lot. You can feed entire scripts to the remote side, you don't have to ssh each individual thing. This would also make your script a lot more efficient.

Thanks for your help but definitly i can't ask for a modification of sudoers.

I resume:

i have to ssh more than 100 machines using a:

Code:

ssh -t myuser@host1  "sudo -u newuser crontab -l"

if i don't use

Code:

"ssh -t"

, the "mysuser crontab" is displayed when i want the "newuser crontab"

but with the

Code:

"ssh -t"

i'm forced to type the password

At the beginning of my script i ask for the password because we are 2 or 3 users to do that.

then i want to enter this password as the

Code:

"ssh -t"

will ask it.

i'm sure there is a special way to do that but i'm not too "expert".

regards
Christian

hi,

no ideas anymore?

i've tried to resume the difficulties , i know it's quite special

Not sure if the version of 'sudo' you're using has this option but there is a -S switch to allow receiving a password from stdin. Although this is an insecure option if someone has access to your script:

Code:

echo -e "password\n" | sudo -S <command>

..but how to try it ?

Code:

echo -e "password\n" | sudo -S ssh -t myuser@host1  "sudo -u newuser crontab -l"

thanks
