No Sudo in Solaris
 

Hi,
i've tried to find whether i've been in sudo list or not ,but i can't able to see any /etc/sudoers files in my solaris box ,so what is the file location for sudoers in solaris
so do i have to install something for getting sudo to work

Yes, sudo isn't part of Solaris 10 or older. You can install it from sunfreeware.com or other repositories. Alternatively, you can use rbac which has similar features.

OpenSolaris bundles sudo but makes use of rbac.

But i think i need to confirm first that i don't have sudo installed ,so for that what will be the location where it'll be normally located
and one more thing i can login by
it ask me username and all that ,but i think it's different for sudoers right

A common location would be /usr/local/bin, alternative might be /opt/<whatever>/bin.

But i can see that sudo is in my command list ,:scratch:where it will be coming from then

Try which sudo
$which sudo
/opt/csw/bin/sudo

Okay, I wrongly thought you were missing the sudo command, not its configuration file. Your sudoers file is probably in /usr/local/etc or /opt/csw/etc.
