I'm trying to use a technique suggested by a fella at this website....
[URL]
He suggests adding an echo line to the actionban line in order to create or add to a file that will contain a list of all the IP's that fail2ban has banned.....but it doesn't seem to generate any output. .....here is the command.....
actionban = iptables -I fail2ban- 1 -s -j DROP
echo >> /etc/shitlist
I never get any IP's in the file so the echo part does not seem to work.

I have 2 questions... I couldn't find answers by Googling (more precisely, by Blackling) and in GCC documents, so I'm asking here.
1. There are 2 flags for position independent code, -fpic and -fPIC. All the examples I read use -fPIC... so when is -fpic useful and what is the difference?
2. Some tutorials use "g++ -shared" while others use "ld" for the creation of the shared library. Why? Does it matter which method I use? Is there a difference? Why does nobody mention both options?

list the used variables.
1. display menu until user quits the script
2. menu would give following options to
a. create backup
b. restore files from backup
c. quit
3. for option a or b user would be required to specify the files and name of the archive]
4. has option to be run with use of parameters if that is the case it will not display menu but carry out required task unless it was not possible to do
5. incase of any errors are encountered it would call external scrpit that would display custom disigned error message.

I wrote a script for capturing port 5060 with tshark.Well, it's only a line, but I needed to send a positional var, and I couldn't do it with an alias. Now I need that script to run as a service, so I can start/stop. (Using CentOS)
Code:
#!/bin/bash
#
# capture service
[code]....
One more thing, my goal is to start/stop the service with
Code:
service myservice start|stop
Is that possible? I read that I must use chkconfig.

bzero((char*) &serv_addr[i], sizeof(serv_addr[i]));

I have created an error logger thread in my application using pthread_create(), I want this thread to have a lower priority than my application's priority so that the application would run properly. Is there an easy way to do this? I know that we can change priority for thread created with policies FIFO or RR, since I don't set the policy for my application, I don't know what to set for my thread.

I need to be pointed in the right direction on how to do this project. I simply want a gnome panel applet that will run constantly and, when clicked, will display an IM style list of I.P. addresses that are active on the network I am currently connected to. It should be able to have a configuration menu that will allow the user to specify a subnet mask, and frequency of scan. I am looking for something that will return something similar to the output of:
Code:
nmap -sP xxx.xxx.xxx.xxx-xxx
My question is: What language should I learn to make this happen, and is anyone willing to mentor me through the process?

I want to create simple webcam effects filters. I am only interested in doing relatively simple image processing like blurring or averaging the color. I would like to create the filters in either C or Python.
So before I dive into using Gstreamer or V4L I wanted to ask the forum if they have had any experience with webcam development?
