General :: About Real UID And Forking?
Feb 13, 2010I'm thinking of designing a software that may need to change the current user to a normal user if run as root. But from what i've read, you can still switch back to root if you were root in the first place (meaning, the real UID is 0). I'd like to make this impossible. I think the solution is forking but i'd like you to confirm this.
My question is, does the real UID of the children is the effective UID of the parent at the time the fork is done? My manual lists what's inherited from the parent but doesn't states this. I'd like an answer about Linux kernel and about Unices in general (i'd like to make it at least POSIX-portable)
General :: Having A Virtual Ethernet Appear As A Real One?
Jan 7, 2011know of a way in Linux to have a virtual ethernet (e.g., eth0:1) appear as a "real" ethernet (eth1)? I ask because I have an old Shuttle box that only has one mobo ethernet and no way to add more. I'd like to use it in my Oracle RAC lab, but RAC requires two physical ethernets. You can't fool it with eth0 and eth0:1. RAC won't setup correctly if there's only one eth adapter, so I'm wondering if there is a way to fake two ethernets. I do not care about performance or reliability - it's my home lab. I fully realize that this violates every principle of HA, but I'm just using it to study. Worst case, I can get a USB dongle ethernet adapter, but I'd prefer to avoid the cost if possible.

Dec 7, 2009I've got the following problem:
1. I start two bash windows
2. In one of them I start a script test1:
Code:
This script puts a natural number 5 times a second.
3. Then in the second bash window I type (as root):
Code:
The script test2 looks as follows:
Code:
While true; do
true;
done
During the following 15 seconds test2 is the process with the highest real-time priority. As far as I know the script doesn't perform any system calls so it shouldn't be suspended even for a minimal timeslice. My question is: why the process test1 manages to put a few numbers on the screen before test2 stops. I thought that test2 would exclusivly own the processor for 15 seconds.

Jul 15, 2010I have a few servers that are exposed to the internet. When someone tried to brute force hack in to the ssh, ossec adds their IP to the hosts.deny. Then the hacker (read: script kiddie) moves to the next IP up the line and hits my next server, etc, etc.
I end up getting 20 emails for all the servers that they hit.
My question, is there anyway to sync the hosts.deny file across multiple servers so that if they are locked out of one, they are locked out of all?
