I am running Ubuntu 10.10 I have an question about the firewall Firestarter, when checking the firewall it told me there are 9 serious incoming connections what must I do with this info. Inbound is normally blocked as standard i have also see that someone with port 1234 and 12345 have trying to attempt mine system but failed all trojan ports are fully blocked.

I'm trying to adjust the firewall to only inbound syn connections.
To Allow all home subnets access to port 53 both tcp/udp but deny the rest.
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?
View 2 Replies View RelatedI'm facing a strange problem. I have a Debian squeeze machine connected to Internet through a 3G USB modem. The machine connects as expected, and I can resolve domain names and establish HTTP and SSH connections.The problem is when I try to communicate to that machine from another PC connected to Internet. The machine doesn't respond to PING and I can't connect to the SSHD installed in it. If I connect the machine to the local network, it works right.

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.
View 1 Replies View RelatedMy 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).
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.
View 3 Replies View RelatedIs 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?

View 1 Replies View RelatedI'm simply trying to make a little restriction on www packets under two rules:
1. Allow inbound/outbound www packets (works!)
2. DROP inbound traffic to port 80 from source ports less than 1024. (DOES NOT WORK!)
Now, technically, when i use hping to test my rules, hping3 192.168.100.100 -S -p80 -s 1023 I should NOT receive any packets. However, i still receive packets, which means my rule that says less than 1024 does not work. (see below)
And this is my iptables rules in shell-script so far:
#!/bin/sh
DEFAULT_NIC=eth0
SERVER_IP="192.168.100.100"
ALLOWED_WWW_PORT=80
IPT="/sbin/iptables"

View 2 Replies View RelatedI've been using Firestarter for a while and have used it to set-up inbound and outbound policies (which are probably way too restricitve) but since turning on boot logging the other day I have noted that the boot log contains the message:
Code:
* Starting the Firestarter firewall [fail] I find this somewhat alarming. I have seen post[URL].ht= firestarter (although have not added it the auto startup list and do not wish to have it start without the root password). What I would like to know is as the computer boots up does it set the iptables to their last setting irrespective of whether firestarter starts or does firestarter need to start to set the iptables and therefore my policies?
what files does firestarter change? I would like to know so I can look at the files so I can learn to do the same thing without firestarter.

View 2 Replies View RelatedI am running ubuntu 10.10. I recently enabled the firewall and installed Firestarter to configure it. Bad decision apparently. I can't connect to the internet using Firefox unless I first stop the firewall using Firestarter. After I do that, Firefox connects to the internet just fine.
If I uninstall Firestarter, will the ubuntu firewall function as it did originally, before I configured it? Or will it continue to function the way it does right now, which doesn't allow me to connect to the internet?
Just want to stealth ports on my laptop. Had problems with firestarter when I installed in on 10.10. Set Firestater back to defaults and then dumped it with:
Code:
sudo apt-get purge firestarter
Set up Gufw to defaults and now am not sure what I am seeing with iptables.
iptables -L shows .....
Do these settings look correct for default settings for Gufw? or do I still have some problems with the old firestarter settings not being removed. All I want is all ports stealthed. I know that ping is enabled but I believe that is a default setting in ufw. Could I restore iptables to default with:
Code:
sudo iptables -F
and then enable Gufw and set default?
There are far too many 'events' in Firestarter's log. I can't find which file contains the log either by searching my file system or the internet.

View 9 Replies View RelatedI 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?
A portscan reveals that port 39878 is 'open', service: 'unknown. I deny service for this port in Firestarter FW 'policy' Firestarter does not show any active connection. I am not running any apps, so how can I close this port?
View 9 Replies View RelatedHave homebrewed machine, was running Fedora 8. Installed Fedora 10.Firestarter firewall manager keeps crashing after about 5 minutes. Restarts, runs for a while, then crashes.Thought it might be an IPTABLES turf war with the native Fedora 10 gui firewall manager, so disabled that at System > Admin > Firewall. Also disabled SElinux. Still have problems.Firestarter firewall seems to work OK, just the gui Firestarter monitor/manager.If anyone has ideas as to cause, I'll take a clue.I could use Firestarter to generate the IPTABLES by ..manually editing the /etc/firestarter/inbound|outbound/allow-.. files and then../etc/init.d/firestarter restartBut I find the events log useful to look at. Anyone know where the events log file is kept in the file system?
View 4 Replies View RelatedI 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.
