How to securely invoke a Solaris privildged command (root) remotely?
Hi,
What I would like to do "securely" is the following.
From one central server invoke a script that does the following.
--Store user/name passwords. (password possibly encrypted in config file)
--From the central server invoke a privileged command (i.e. route add) on multiple servers.
High-level Steps:
1. User logs in Central Server
2. User Invokes "the script"
3. "The Script" --> SSH to <server(s)>, script invokes "privileged command", User has sudo-access to the "privileged command" only (everything should be logged).
Question:
What security issues can I potentially have with the above approach?
Is there other obvious (standard??) way to invoke privileged commands remotely that do not require some sort of agent running on each server? (Do I need an agent on each box??)
Would the new feature of Solaris 10 privileges help me in any way?
Your thoughts/advice on the above would be greatly appreciated.
Thanks
Sam

Ok,
I am trying to install solaris, but I would like as a lean installation as possible (while still having a shread of functionality).
If I chose the minimal install I have little if no utilities to do work on the box.
My question is what installation method do most admins take?

root_archive
root_archive(1M) root_archive(1M)
NAME
root_archive - manage bootable miniroot archives
SYNOPSIS
/boot/solaris/bin/root_archive pack archive root
/boot/solaris/bin/root_archive unpack archive root
/boot/solaris/bin/root_archive packmedia solaris_image root
/boot/solaris/bin/root_archive unpackmedia solaris_image root
The root_archive utility is used to manage bootable miniroot archives and is currently only available on platforms. The utility can pack
and unpack boot/root archives in both ufs and hsfs (iso9660) format. It will always generate ufs archives.
root_archive also uses the lofi file driver to export a file as a block device (see lofi(7D)) and mount to mount or unmount file systems
and remote resources (see mount(1M)). root_archive requires the same privileges that are needed to run these commands.
SUBCOMMANDS
The root_archive command has the following subcommands:
pack archive root
Pack from the image found under the root directory to the archive.
unpack archive root
Unpack from the archive to an unpacked image under the root directory.
packmedia solaris_image root
Pack the solaris image to the root directory.
unpackmedia solaris_image root
Unpack the solaris image from the root directory.
For packmedia and unpackmedia, other items that do not go into the ramdisk image are copied or uncopied (see cpio(1)) as well. Specifi-
cally, this includes all the packaging databases needed for pkgadd and the other packaging utilities to succeed which are not used in the
running and hence pruned to conserve memory.
EXAMPLES
Example 1: Unpacking the Solaris x86 install image
The following command unpacks the current Solaris image from the root directory:
# root_archive unpackmedia
/export/nv/solarisdvd.nvx_dvd/latest /export/Boot
Where /export/nv/solarisdvd.nvx_dvd/latest represents a path to a Solaris x86 install image and /export/Boot is a directory that will be
purged or created, as necessary.
Example 2: Packing the Solaris x86 install image
The following command packs the current Solaris image to the root directory:
# root_archive packmedia
/export/nv/solarisdvd.nvx_dvd/latest /export/Boot
The following exit values are returned:
0
The command completed successfully.
1
The command exited due to an error.
