I installed fail2ban from the Ubuntu Software Center (Ubuntu 10.10) and everything seemed to go fine. But when I try to access the client I get this output:
Code:
wolfgang@Culture:/var/log$ fail2ban-client status
ERROR Unable to contact server. Is it running?

I'm trying to implement this method to block php injection attack using fail2ban: here it is, however I'm not sure it applies to Ubuntu. You see, there's this filter that must be added to the fail2ban jail file:
HTML Code:
[php-url-fopen]
enabled = true
port = http,https
filter = php-url-fopen

Currently suffering from this bug:If you don't want to read the whole thing, it appears fail2ban overloads IPTables when you have too many jails, and sends a whole load of commands at once.I attempted to use the workaround making it sleep for a random period of time, but this does not help at all, it still fails like it used to.Any ideas? Fail2ban is a pretty popular app...Ubuntu 9.10.
Code:
$ aptitude show fail2ban
Package: fail2ban

I have been trying for days now to get this to work. didn't want to bother people with my questions, i have installed Fail2Ban 0.8.4 on CentOS 5.4.
I get the email notifications from Fail2Ban stating that it just blocked another IP, however, when i look at the iptables through webmin, nothing is actually in there, also the log/secure file dose not show that the ip has been blocked.
Even when I try to log-in with the wrong password, after a few tries i get the email telling me that my ip is blocked, however, I can still SSH using my 'blocked' IP.
I yesterday installed fail2ban on my server and I see I am not getting logs for the genuine people also who log in to my machine.In

Is there a firewall installed and running in 10.04? If so are there any gui tools for configuring it and where are they? If there is not a firewall, what should I install to get one properly up and running?

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'm getting loads of hacking attempts on my pop3 daemon. Looks like fail2ban is not stopping it. How to ban these type of attacks?

i have fail2ban on server but everytime fail2ban conducts a log rotation it unbans all the banned IP's. I have ip's to be banned for a week whenever a log rotation happens or i restart fail2ban i dont want all the ip's released! I was thinking there was a script or patch that would fix this but i have come up short.
View 2 Replies View RelatedI've had fail2ban setup for awhile for my SSH server, and that works beautifully (I had someone I knew attempt to access it and get banned) however I then tried to set it up to ban people scanning my webserver for lots of other pages which dont exist (and have never been linked to) such as phpMyAdmin.
In my jail.conf I have:
Code:
However Looking at this I realise I need to edit the filter.d/apache-error.conf
I'm not sure exactly how to setup the regex to ban the correct hosts
The errors from the scanners are like this:

I am having issues getting yum to work with the repos for fail2ban and denyhosts. I followed the centos link on installing/cfg repos. However every time i run yum install fail2ban or denyhosts it does not find the software. I read in several google searches that I should be able to install it using yum. Is that info wrong? These are the link I was s reading too from centos. [URL]. I know I can download the rpm or a tar file but I would like to keep it in sync with yum if possible. May be I have the wrong repo? CentOSPlus is enabled also.
View 3 Replies View RelatedI was wondering about the security implications of running a GUI in a VM. I know that a GUI adversely affects security, but don't know how this works when visualization is thrown into the mix.
1. Is the security of the host OS affected by the presence of a guest OS with a GUI, or is it just the guest OS that would take the hit?
2. If the host OS does not have a GUI, and the guest OS does have a GUI, would it be possible to see the GUI of the guest OS?

I do in fact have it running. Veryfied it with mysql command on command line and it complained with missing attributes.
I read a thread that it needs php-mysql installed. So went to proceed to install it. Well, I did not have that and went to install it. Verified it. Package mysql-server-5.0.77-3.el5.i386 already installed and latest version
I then did a service mysql reset.
Checked back at the joomla web install interface and still, it says there is no mysql support! What is next? Im running centos OS. Also, I am running LAMP
