I dont know how, but somehow all the ports on my comp appear to be blocked except for 24, for ssh and 5900 unknown. I can connect to the network, but as far as I can tell, I'm powerless to do anything. No webpages load, I'm typing this on my phone.

All ports are blocked only 22 and 80 are open. I scan localhost and ports are open. When I scan IP address ports are blocked.I have no firewall rules.
View 5 Replies View RelatedI have a vps server running certain services which can be accessed via a web browser (e.g webmin control panel), but I have recently been unable to access these services from my home machine using Firefox 5.0, running ubuntu 11.04.
Example:
I can access the server on port 80 fine, eg: [URL]
However I cannot access my webmin control panel on: [URL]
The pages takes ages to load and then times out. Same with transmission-daemon on: [URL]
Everything is set up fine on my server, the ports are open in firewall etc. and I can access these pages fine from my work computer.
This has only started happening in the last day or two and had been working fine up till then. I have not messed around at all with the firewall on my home machine. I have tried other browsers besides Firefox with same result.
Is there anyway i can ssh/rdp/telnet into my server from the outside bypassing comcast ALL blocked ports

Apparmor wasn't the problem. The network hard ware is not the problem.There is something inside of 10.04 that is blocking port 80. I can ping it all day using the ip address but when I ping it useing http://ipaddress it can't find the host
View 4 Replies View RelatedIn my Ubuntu 9.04 installation, just a few days ago, I lost my usage of the internet. I still had internet access. Firstly though, there was a problem with the router, so I tried a friend's router (both Netgear DG834) and the friend's one worked. But in Ubuntu, I could not access any web pages or email. Skype works.
I tried using my netbook and that could access web pages okay. So then I booted my main PC into the old installation that I kept there of Ubuntu 8.04, which I am using now. And in this the internet works just fine, I can access websites and download and send email.
But in Ubuntu 9.04, it seems like something is blocking my access. I do not recall installing anything new, although something may have been updated recently. I can see the DNS servers from Ubuntu 9.04 and it gets an IP address from the router. What is the likely cause of the Internet being blocked for websites and email (but not Skype)?
I recently installed the XRDP server on my desktop edition of Ubuntu v10.04 following the simple instructions available here. I did this on two computers. One computer has Firestarter installed while the other does not.
When I use Windows to connect to the Ubuntu box without Firestarter, everything works just fine. However, when I try to connect to the one running Firestarter, I get a pop up showing an error message (see the attached file).
I checked the incoming rules in Firestarter and I don't see a way to add RDP sessions to the list of exceptions. I also tried adding my IP address in the host section but this too didn't help the situation.
I can't seem to establish a conncction to my site (that I'm hosting in the same computer as the gFTP client- running Lucid Lynx desktop as a server). My site is 'out there', with a domain etc. and also I work on it with localhost. I wanted to use ftp as Joomla has a 'ftp layer' for files permissions etc. But it keeps saying that I can't connect, or the connection 'was reset by a peer' whatever that means. For 'hostname' I use site.com (site is my site's name) and even tried the whole thing like http://www.site.com (I clicke on 'connect to remote, and enter that in the url). or just put it where 'host' goes (when I'm not using localhost) For user name and pass, I just enter what I usually put to access the administrator's back panel in joomla, but maybe I am supposed to use what I use to log on to ubuntu when I start my computer? note sure. Anyway I used a telnet command in the terminal and found that port 21 was blocked. MY isp says they don't block any ports so I don't know. I was able to do this last year so I don't know what is so hard about this lol In the router, I have 'ftp 21 to 21 and ip address 192.168.1.100 (ip is the same for http which is working as I have my site up) now it seems to be open as I used a command at the terminal (found from google). It's open but my ftp still can't connect to my server either localhost or to my site. there is no firewall blocking it and I think my router is set right.

I connect to the internet at work through an authenticating proxy, and to avoid having to enter the proxy info into every app I use (e.g. firefox, wget, kde, etc) I have set up squid as a local transparent proxy which authenticates and routes all traffic to the work proxy. It has been working fine, but lately I haven't been able to connect to any https sites. I don't think I have changed the configuration, so perhaps it is the result of an upgrade, or something badly configured on my system from the start. I have tried connecting to https sites without squid and iptables and it works fine. My system is Arch linux, and my squid.conf file is: Code:
acl all src all
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8

View 11 Replies View RelatedLast night I installed all the updates that were available for CentOS. Today, I discovered that all connections to port 25 (Sendmail) are being blocked except connections coming from localhost.
I tried disabling the firewall to see if anything would change but it is still blocked.
If it is not the firewall doing the blocking, what else might it be?
Recently I discovered that we were accidentally running a POP server (port 110), when we only should have been running the encrypted version thereof (port 995). This wouldn't have been a problem if the port was blocked in the first place.Isn't the default iptables setup on CentOS to block unspecified ports? Specifically, this line from /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
Right? Well, this doesn't seem to be working for me. I added some rules to allow additional ports and commented out a couple (crucially port 110), but for some reason, port 110 is open.Here is /etc/sysconfig/iptables and the output of iptables -L below that:
# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]

Why isn't "-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited" doing what I think it should be doing?

View 3 Replies View RelatedA few months ago I installed Ubuntu 9.10 on my girlfriends laptop, on her request, as she didn't like Windows any more. Since then the internet connection periodically slows down due to too many open ports/connections. Always when this happens I call our ISP and usually there are around 80-200(!) active connections to various IP's.
She is not downloading torrents or anything.
She only uses Firefox and a few open tabs as people do.
Skype is open.
Wireless internet connection.
I am thinking either Ubuntu is updating more or less constantly or the ports/connections aren't closed "after use".
Does any body know how to enable ports in ubuntu 10.04?

I was following the directions over on the page How to watch Hulu overseas without a proxy server and got to the section about blocking ports, which I need to block port 1935. I figured this would be easy, as the mac instructions are
Code:
sudo ipfw add 0 deny tcp from any to any 1935
sudo ipfw add 0 deny udp from any to any 1935
and the Windows instructions are practically a book in itself. Since this page was lacking instructions on how to do it in Ubuntu, and ipfw seemingly doesn't exist in Ubuntu, how do I block the ports
I'm trying to open my ports all the way, but for some reason, I am unable to do so. I've forwarded the ports I want open in my router (I switched between two routers to make sure), I made exceptions in Firestarter, and I even added UFW rules, but when I use pretty much any and every port checking tool out there, the ports eithere back stealthed or closed.I'm not a complete noob, and I'm not an expert, but I'm p sure I'm doing everything right, seeing as there isn't much to screw up.The reason I'm trying to fully open these ports is because I'm getting this dumb 'No Incoming Connections

View 2 Replies View RelatedI have been running Ubuntu 10.10 and have found that at any time I am connected to the Internet that I will randomly see high port numbers open when doing a port scan on my computer all are in the unknown listings with five digit numbers so I don't know what is going on or who is using them. Please check your system to see if you are having the same thing happen by using network tools and filling in your local ip address in the port scan tab. If you shut down your Ethernet interface and run port scans the high ports are no longer open. this will at least keep whoever is using your ports at bay when you are not using the net.
