I'm trying to disable the firewall in an attempt to get my computer to see my other computer connected to the router. However I'm unable to get the firewall app to open. Here's the error in the attachment. It just says a float is required. My only options are to redo, which keeps the same error coming back, or to quit which closes the whole thing.

I am trying to make a vnc connection from pc #2 to pc #1. Pc #1 is a debian pc behind a zyxel router (P-2602HW-D1A). Pc #2 is a windows xp pc another place at the internet.I have configured the zyxel router to forward incomming trafic on port 5902 to the local ip-adress of the debian box. The debian box is running a vnc server, listening on port 5902.But i dosn?t work.I have tryed to scan the zyxel routers ipadress on port 5902 from the internet, but the scanner says that the port is closed.The vnc server on pc #1 is working fine on the local network. I can connect to the server from a pc on the same side of the zyxel router.Is it deffenitly a router problem, or could it have something to do with debians own firewall?

But the first few days, I couldn't open the firewall from the menu because it always crashed. From terminal no problem. This was with a couple of these standard gnome apps. With the 'autmatic bug reporting tool' I can now see how many times each program crashes. Samba still crashes every time I try to open it, python crashed, firefox loves to crash these days (with a flash open), amsn crashed a couple of times (empathy and telepathy-butterfly packages).Ofcourse I update my system every few days, so I have the latest updates of each package.

I am having brand new IBM server with two NIC card and want to setup Firewall. I am searching for good solution which suits to me. Which firewall system I should go for? I am thinking of IPCop.
1) Firewall should support OpenVPN
2) Easy to manage for Resident technician
3) Should be block streaming, facebook and others sites.

View 14 Replies View RelatedI have just switched over from firestart to gufw.I have set all incoming traffic to deny and all outgoing traffic to allow.I have rules set for incoming traffic, and have only opened 1 port on my system for torrents. My router also only has the same port opened which again is for torrents.I use "Network Tools" which is included on squeeze and do a portscan of 192.168.1.100 and 127.0.0.1 I get all kinds of crazy ports coming back as opened. What is even stranger is if I do a few scans, these ports change, so one port on one scan may come up as open, then it will disappear and a different port may show as open.
Mind you none but the torrent port is forwarded in my router, I have no idea what any of these other ports are, or why they are even showing up.What the heck is going on? I dont think this is normal? Am I at any higher risk for attack?
how to open firewall ports without using yast. The reason I'm asking is because I'm working on a .sh script for the installation of a couple of programs. Some ports need to be open for the programs to work, I find it really annoying to go to yast and type the ports manually every time. I've looked at /etc/sysconfig/SuSEfirewall2 but can't seem to find anything, I also know that after the changes I will have to stop start the firewall by running:
SuSEfirewall2 stop
SuSEfirewall2 start
I'm using version 10.04 (lucid lynx) and need to find out how to open my firewall in terminal.

View 2 Replies View RelatedI have a couple of openSUSE 11.2 machines and each is directly connected to the Internet (they are not behind a router, firewall, etc). I want them to be able to communicate without any firewall restrictions, but keep the firewall rules for all other IP addresses. Is this possible? the software package I'm trying to use randomly chooses a port to use in the range of 32768-61000 and I don't feel comfortable having a port range that wide open on both machines.
View 5 Replies View RelatedI have properly configured my router to open a port for Transmission and Vuze. The OpenSuSE firewall settings are somewhat confusing, however. How do I add a port specifically for the BT protocol? I know it's the firewall causing issues, because when I shut it down, my BT apps roar to life, and die with a whimper when I turn it back on. In Ubuntu, opening a port in the router is automatically configured in the firewall; that is apparently not the case with this distro.
So, when I go to Yast Firewall, I see "allowed services" under the tabs available. When I hit that tab, I see a dropdown menu that contains services such as NetBios Server and Samba Server. Am I choosing one of those available and adding a port to it? Am I adding a custom service via the Advanced settings, and if so, why isn't there a way to label the service so that it shows up under allowed services?
I am having trouble getting ports to open, on the router that the server is connected to it is set to DMZ, so everything passing through the router should go to the server right? but when I use a port checker none of the ports that I need to be open are. so my question is does ubuntu have a built in firewall that no one told me about? or something that would block me from having the ports open?
View 3 Replies View RelatedI have a local install of Wordpress and I've added a port forward rule in my firewall to share our site with family and friends (we're using a members only plugin). I have a DYNDNS account and my router automatically updates with this account.The problem I'm having is when I test accessing our local site from outside my network. I use my dyndns account name and port number to access my local Wordpress, I can see the login screen but once I login, the url changes from my dyndns name to the IP Address of my local server and then I never see any pages on my site.
I'm thinking it has something to do with either the WordPress address (URL) or the Site address (URL) since they currently have the ip address of my local ubuntu server that hosts our Wordpress site.So what have I configured incorrectly here?

View 1 Replies View RelatedI would like to ask today how to open up specific ports in Linux firewall (iptables). Recently I have changed the SSH port in server from 22 to 30022 by typing

Just installed Fedora 12 on a P4 IBM. Everything installed fine. Then, I rebooted, installed updates, and installed a few simple programs (emacs, ssh server). I rebooted since some kernel updates had been made. I can't login anymore. I get a brief message at GDM that says "unable to open session" after I enter my password. Root also doesn't work, but I figured out that root logins are disabled. I found something that recommended disabling selinux, so I reboot with selinux=0 parameter. That still didn't fix the problem, but did initiate selinux to re-label everything on the next boot.
My next thought was that maybe my password got corrupted, so I went into single usermode. I ran passwd justin, so I know that my password is correct. I still can't login via GDM or on a tty.
EDIT: I was also thinking I might need to uninstall something that I did; however, networking is disabled in single usermode, and if I init 3, then I get a login prompt that I can't open. Is there a way that I can enable root login? That might be a starting point to see if it's my user account or a general login problem.

I Made a fresh Installation of Fedora 13. It shows VolGroup00 and File System in the Computer on desktop.
The size of the hardisk is 160gb. The file system shows some 4gb. I'm not able to open the Volgroup00. On double clicking it it shoes the error "Unable to mount location"
on entering fdisk -l,
It says the partiton one /dev/sda1 did not end on cylinder boundary.
The partition /dev/sda1 ends on Cylinder 63 and the emaing LVM partition also starts on Cylinder 63.
I tried reinstallling after dropping both the partiotions 4 times, but this is always the case.
I am trying to understand why when running nmap against a SonicWALL firewall at a remote location, the SonicWall firewall is saying that most of its 65535 ports are open? I know this cant be correct and remember reading about how some of these network appliances are setup this way to thwart off attacks.

I have installed Fedora 10 and centos 5.3 on 30 system in my home office. everything works fine except accessing https websites. the problem persists in both centos and fedora even after changing firefox versions. what's worse is the problem is not resolved after changing other browsers. so the problem is not browser-centric. i think it has something to do deeper in fedora and centos. also note that i have disabled firewall and selinux but in vain. the problem is still there across all the systems. it's really a show-stopper for me.
View 7 Replies View RelatedI clean-installed Fedora 11 and everything was running well. I wanted to try Bacula backup program and so I installed the Development package in other to compile Bacula. When I finished the installation, I discovered a bunch of foreign language supports had been installed. I just erased them. While doing so, I must have also erased some other files.
When I rebooted, the bootup process went well until just before the login screen. The screen showed the Fedora logo, f, and got stock there. I was able to login remotely from another local network computer via vncviewer. I found that GNOME dsktop was missing. I logged on to Fedora 11 text mode by issuing CTL+ATL+F3 and did 'yum groupinstall "GNOME Desktop Environment" By remote login from another computer, I determined that the GNOME Desktop had been restored. But the Fedora 11 still stil stuck just before the login screen. What do you think is missing? What do I need to reinstall?
I am using Fedora 14 and i am unable to open a few sites e.g

I have a question about /etc/services file. If I open ports in firewall, do I need to alter /etc/services file in order for certain apps to work?
kpasswd 464/tcp # kpasswd
kpasswd 464/udp # kpasswd
# Theodore Ts'o <tytso&MIT.EDU>
# 465 is illegal used by eMail Server
smtps 465/tcp # eMail Server
#urd 465/tcp # URL Rendesvous Directory for SSM
igmpv3lite 465/udp # IGMP over UDP for SSM
# Toerless Eckert <eckert&cisco.com>
digital-vrc 466/tcp # digital-vrc
digital-vrc 466/udp # digital-vrc
Above example shows if 465 tcp isn't altered, Postfix MTA fails to listen on 465 tcp port. What if there's a bigger span 3000:7000 TCP/UDP, is there a need to alter each line by hand?
How do I open ports 5198/udp and 5199/udp on a slackware based firewall?
View 2 Replies View RelatedI now have a firewall up and running: almost perfectly. When I use nmap and perform the most comprehensive scan I can think of, it cannot detect any wide open ports (unless bittorent is running) and cannot fingerprint the OS. My last 2 questions about my firewall (I am very happy now) are:
It seems as though Firestarter has been "abandoned" by the developers, and that gufw is more current. Does it really matter which firewall I use because don't they all do the same thing? I like firestarters system tray icon a lot. 2nd question is I have two open|filtered ports. Are these still pretty well protected?
It is very pleasing to see that I have no open ports, because if you were an experienced Windows user like I was, you got used to the fact you were going to have open ports no matter what. Linux's builtin firewall completely destroys the expensive and useless scams they call Norton and McAfee. Linux officially rocks now
