Writing a script to access many servers
Hi there,

I'm writing a simple script (in a batch file) to access a number of servers with a number of different credentials (users/passwords/root passwords etc). What I need is a way to execute commands as root. I'm currently using the batch file to read the server information out of a text file one by one (with usernames/passwords) and then using plink to connect to servers and a text file with commands in to download/install what I need to. The problem comes when I need to be root to install the software.

Now i've seen many threads on the internet stating that it's practically impossible to gain root through doing su and dealing with a prompt for the password. I've done alot of playing around but to no avail.

What i'm wondering is if there is any way to get around this? I'm aware of Expect but I can't install that on all of the servers. Maybe someway I can log in and gain su rights at the same time?

If you want to login as root, arrange sudo in advance. If you want to ssh in without a password, arrange ssh keys in advance.

If you are not permitted to do these, I doubt you are permitted to insecurely bruteforce a plaintext login with a plink password either.

Thanks very much for the reply.

I suspected as much, I know the solution i'm trying is far from elegant. I'll see if I can arrange sudo for the install I need.
