General :: Firestarter Denying Connections On Ports 80 & 443 Despite Settings
Apr 19, 2011
My firestarter is denying connections on ports 80 and 443, despite the fact that I have set rules to allow both the services, and indeed any connection from my gateway (the source of the connections).
Can someone please advise why this might be?I can surf the 'net fine, unfortunately I cannot load facebook, gmail, or another couple of sites that require logins, and I assume this is due to HTTPS not communicating properly.(On the off chance anyone can answer these real quick, I'm also trying to solve my resolution resetting every time I restart, and one of the icons in my KDE panel turning into a widget from an icon every time I restart. Still working on these, but just if anyone knows already).

Firestarter sometimes shows up to a dozen different ip connections for a single webpage that I open. This is for the first webpage I open, not after I have been browsing for awhile so they are not old connections that have not timed out. This just doesn't seem normal to me since other installs I have had of ubuntu have only shown one or two firefox connections at all times.

I am running Firestarter on Ubuntu 9.10 64 bit. I have noticed several times that after closing all web apps (Firefox, Thunderbird) that some entries remain under the heading "Active connections" on the Firestarter "Status" tab. Often these show no source program. Currently I have 2 showing which show Firefox as the source. These persist after Firefox is shut down. I have verified that no Firfox process is running. And both of the IPs point to google.I have Disconnected eht0 and they still show. I have logged out and back in and they still show. I must reboot the machine to make these entries go away. Which makes me think perhaps this is a bug in Firestarter(?) Is there another way I can identify truly active connections?

I am trying to configure Bittorando and iptables using Firestarter. I have got it working but am concerned about security holes.
Let me explain.
AIUI, the Bittornado program contacts the "tracker" on various ports which (from the previously blocked connections in Firestarter) ranged from 4664 to 65532. Therefore, currently I have set this range to be open to allow downloads of the torrent.
However, this seems, IMHO, to devalue to point of having a restrictive exit policy for Firestarter since now virtually all ports are open. I can see nothing on the Bittornado client to restrict the outgoing ports although the "listening" (incoming) ports can be restricted.
I would prefer to have my system locked-down so that the minimal number of ports are open to initiate external connections so is there any way to achieve this with Bittornado?

I've noticed that when I open firefox I get really strange HTTP and HTTPS connections showing up in firestarter (which as I understand it is just a GUI for IPtables). They connect to various bits of a site listed as 1e100.net (when you use "lookup hostnames") such as wy-in-f18.1e100.net, they stay connected all the time as far as I can see unless I close firefox. I've heard people say they are connected to Google, but I can close all tabs after loging out of google and still see them... it's very odd.

I'm trying to setup my debian system so that I can access it's services from the internet
I have my router set to forward ports 21, 22, and 80 to the internal ip of the server, and internet port checking tools tell me the ports are open at my external ip.
On the debian I am running Apache, ProFTPD, and SSH Server, and they all work fine for me inside the network, but whenever I try connecting with my external ip, all connections are immediately refused.
So I don't know if its a problem with my router setup, with my debian system setup, or the setups of the servers.

I have recently bought a IP/PABX system with one FXO and one FXS port. I intend to install this on a remote site with a public but dynamic IP (can be resolved via dyndns though) and make calls via clients that are NATTed (inside a home router). I would like to seek advice on the port opening and the recommended settings. I have been reading a lot on VOIP and I am getting feedback that SIP calls are difficult to establish on a NATTed environment.
1.) SIP port 5060 UDP?
2.) RTP ports - what range should I open for this? I see some use 10000-20000 UDP
3.) STUN server - Is this something that needs to be configured?
How can I ensure that the other party can hear the audio just like a regular telephone? Is it really impossible to do if the client is behind a router in which it is using a Private IP Address? What other network configurations needs to be done?

I installed firestarter and then at a later date uninstalled/purged it, both actions via synaptic. I have a very verbose boot, I like to see what's going on, and noticed after the uninstall/purge that I was getting an error zooming up the screen containing firestarter in it. After many restarts I found that a file was left in /etc/network/if-up.d/50firestarter and this file was simply a script trying to restart firestarter. At this point I've commented out the calling line and followed the commented line with exit 0. This removes the error but there's still a link calling the file so, is this a bug or am I missing something? It appears the uninstall/purge wasn't entirely complete.

Just had ModSecurity with CRS installed for me on my hosted website, which I'm hardening after a recent hack. My site is a php-based user community with MySQL back end, so people register as members via php.
First, I'd like to properly log malicious activity Then I'd like to deny access where an attack looks likely Thing is, I'm not sure which /etc/apache2/modsecurity_crs modsecurity config files to tweak.then I can't even see my login page because I'm forbidden from the .php file it loads.I'm guessing I need to change rules individually but I have no idea how or which to change to stop attacks. The CRS documentation is just a bit too heavy to give me the basics.

Just installed UbuntuStudio 10.4 X64 next to my main Ubuntu 10.4 X86. For some reason the network-settings app is not working right.I use a Netgear WG311v3 wifi card to connect to my home network and I'm a pro with using ndiswrapper to emulate the drivers for both 64 and 32 bit machines. Everything driver-wise works and iwconfig shows my card as installed and working.When I want to connect to the network I go to System > Admin > Networking to set everything up. But the problem is, there is no "Connections" tab. Only "General", "DNS" and "Hosts". So I cannot select my wifi card to set up the ip's and everything. I haven't tried using a normal UTP cable, as it's quite a hassle to extend it to my room, but I'm sure I will get the same results.How come everything works hunky-dory in Ubuntu, but not in Studio? It's exactly the same!

We use PAM to control access to our RHEL4 servers. We would like PAM to give a message, of our choice, when users who are not allowed to login try to login. PAM's default is to let the user try 3 times without any explanation.

I am working on ubuntu right now and it is quiet easy to install firestarter firewall on ubuntu thru GUI interafce but my requiremnet is to install firewall on target (powerpc 8560 ),so i have to compile firestarter source for target powerpc (montavista linux) and installed it on target. I have downloaded firestarter-1.0.3.tar & .src.rpm file both but not able to compile it for my target which is powerpc (8560).
1.How to compile source code for powerpc ( I have environment created for ppc compilation but do not know how to modify the configure file to change the compiler) because it is compiling firestarter source code with gcc compiler bydefault i. e for host. How can i change the compiler " CC "? 2.What will be the executable created to be installed on target after compilation ? 3.Is the cross compilation for target is possible?

I have installed the graphic user interface for IPtables and enabled this firewall. However, I find it a bit strange. What is the difference between rejecting and denying the traffic? If I want to configure IPtables as two-way, how can I define which of my apps can connect to the internet and which can't? If this firewall is enabled, does it really run in the background, protecting the user,or does it run only when its GUI is opened?

My apologies if this is the wrong board for this thread, but seeing how the issue appears to be related to where I'm connecting from, I thought this would be the place to look.To start off, I've been running VSFTPD on the box for a good year or so now. Until recently, everything seemed to be working fine, but during the past few days I've run into issues with it and have been having trouble pin-pointing the problem. I've gone as far as reinstalling VSFTPD and rechecking every line in the conf file to no avail.The issue presents itself when I try to login to the FTP server remotely. The moment I put my user name in, I get disconnected without any error message, simply connection closed. That isn't the case when I'm connecting locally from the server.If I try to connect remotely using eth0 (internal network), it works fine again... but if I try eth1 (external network)... it fails. I'm thinking it might be related to PAM, but so far have been unable to figure out what I need to change in the configuration there. Additionally, the PAM log file doesn't show any activity if I'm connecting through eth1, but displays it if connecting through eth0.

Is it fair to say that connLimit and hashlimit are very similiar on Linux i.e. while hashlimit caters to limits for groups of ports, they both set the connection rate limit per host? How in IPTables, do I configure a policy that limits connections on a port that encapsulates the total sum of all connections from all hosts? i.e. I do not want to allow more than 6000conn/minute for port range that is the sum of all connecting hosts?

I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.

I'm working on a Linux (fedora) based arcade dance machine using a game called Stepmania. I've got it all up and running and i'm trying to get it to work with two dance pads.
It detects the dance pads fine and they work well, the only issue is that when the machine is turned on it seems to randomly pick which pad is /dev/input/js0 and which is /dev/input/js1
What this leads to is the pad on the left controlling the character on the right & vice-versa. So I was wondering if there is any way to tie or map the joystick to a particular USB port so they always stay where they should ? Or is there another way this could be accomplished ?
