so, these are the messages.
We have installed Fedora 6, x86_64
My questions are these:
1. Why postdrop try to read, append, get atribute the apache logs. Is
can be because we have installed Logwatch program. We get these in all
servers.
2. I have to allow postdrop to make what is needed with the logs, this
is secure and it will not be problem for something?
3. For the last one, httpd, try to connect to postgresql socket, why
this happen and is it secure?
4. I have to give this permission of httpd to connect to postgresql.
We have set postgresql to work on localhost and not to execute queries
from remote host and sites.
I will wait for your opinions, thanks in advanced.
Regards, Ali Nebi!
