Hey guys,
I use this utility dpkg-reconfigure to configure already installed packages on Debian Ubuntu. I was wondering what to use for this purpose on Centos??

For configuring services try chkconfig or ntsysv?

well rpm packages don't natively ask any questions, so I don't see what's to reconfigure. Not something I've ever needed to do. You can relocate *some* packages with the --relocate option to rpm if that's relevant.

Actually, I'd wanted to reconfigure sendmail - the package, not the service.

Guess that answers it, means i need to edit the config file in the /etc/ directory, its strange though because when I do yum install [package], it installs with certain defaults, thought it should ask for my preferences.

Either-ways, this is what I want to do, I have installed sendmail and I want to change the domain where the emails come from by default it just takes the hostname, anyone know where to change to manually specify a domain?

http://www.centos.org/docs/2/rhl-rg-...-sendmail.html or http://www.centos.org/docs/5/html/5....l-default.html

There is no "reconfigure" option under CentOS package management tools.

Thanks,

more reasons to love debian!

Just edit the /etc/mail/sendmail.mc file directly (although postfix is much nicer to configure)

No, i'd totally reject that one. You may be able to automate a few arbitrary basics, but you can't cover everything, so you end up in a weird state of having multiple ways to do different levels of config. No thanks. just edit the config properly.

reconfigure is no substitute for knowing what|where| and how to do system administration.
It actually can inhibit learning.
Anything reconfigure can do for you, you can do for yourself.

reconfigure "can" actually help restore things to default settings, but I have seen a couple of packages in Debian-derivatives that actually been made worse by reconfigure.

Make a cp of /etc/mail/sendmail.mc and edit the /etc/mail/sendmail.mc as Chris suggested.

Don't forget to restart sendmail after making changes to the /etc/mail/sendmail.mc file.

Good luck.

Total agree with you guys, guess I was just been lazy

Good sticks to wake up, thanks guys!
