disable alias?
 

I was following a tutorial on hardening linux, and one of the modules they disabled in apache was alias.

I was getting an error with it, and apache was not booting/restarting, and so I then decided to enable the module again, and it seems to work ok now. Is there any benefit to disabling the alias module in apache?

I suggest you read from the source...http://httpd.apache.org/docs/current/mod/mod_alias.html and you can make your own assessment. And before "hardening anything", make regular backups.

Did this "tutorial" say why disabling this was needed?
Post the URL for this tutorial.
What you read is every bit as important as where you read it.

So it maps urls to system files? so if I want /var/log/log.log, I would have to have this enabled?
here is the tutorial link: http://www.thegeekstuff.com/2011/03/apache-hardening/

for what, pray tell?
Leave it alone. it has NOTHING to do with apache OR securing Apache.
