Ubuntu Networking :: Can't Access Any Site / Email / Bittorrent All Come To Screeching Hault
Nov 29, 2010
Using Ubuntu 10.10 I have a VPN account with VPNtunnel.se. I configured everything as described on their site. It uses OpenVPN It connects no problem. However; after it connects instead of having a nice secure connection I have no connection at all! I can't access any site, email, bittorrent all come to a screeching hault. The service works fine in Windows. I'm useless with linux networking.

I don't know what's wrong with my Ubuntu but everytime I open Transmission BitTorrent Client, the internet connection become unstable from time to time. Internet access run smooth without it but I need it to download file from torrent...
I used Dual-boot with XP and Ubuntu and I got no problem with 9.10 Karmic Koala but just got this problem after upgrading to 10.04 Lucid Lynx.

Trying to access 67.15.245.6 (its a forum site). I can't get to it from home for over a month now. I can't ping it, but I can ping obvious things like google. Tracert isn't working at all. Once it hits the lightspeed.frokca.sbcglobal.net hop it just dies like ATT isn't allowing traceroutes. I've been using Tor as a work around. About 3 months ago I basically had the same issue with openbittorrent.com's site.
I have a linux server and windows XP box. I can't ping the above IP nor tracepath/traceroute to the IP from my linux box.
I have ATT uverse.
EDIT: The site is hometheaterlounge.com (The IP won't do you much and its just the IP of the site host).

How can I block access to a certain internet site using ufw? Let's say I want to block access to www.xxx.zzz (IP 1.2.3.4) to any program and user; using iptables I can do
sudo iptables -A OUTPUT -d 1.2.3.4 -j DROP how can I do that using ufw? if ufw can not do this, where should I put this rule to persist it over reboot, without interfering with ufw chains infrastructure?

When I'm trying to access my site using Firefox I get this error: "Unable to connect
Firefox can't establish a connection to the server at mysite.com.
-The site could be temporarily unavailable or too busy. Try again in a few moments.
-If you are unable to load any pages, check your computer's network connection.
-If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."
Then I tried to access my site using Opera and Chrome but I get the same error, that the browsers couldn't connect to it.
The site to which I'm trying to connect is definitely up. (I ask a few people and they can access it and I looked at [url] and it says that my site it's up)

In the office there is a local network with samba+openldap PDC. The local domain name is company.net. The company desided to create a corporate Website on a remote hosting and desided that the site's domain should be company.net which is same as local network's domain name. So now it is not possible to reach that corporate website from within the company's local network because, as I guess, bind9 which is installed on above menioned PDC looks for company.net on a local webserver. Is there a possibility to let people from this local network browse the remote site?

Is there a way you could update content on a web page from an incoming email on a linux server? e.g. you email your comments to an email address and the contents of your email (comments) appear on a web page. (preferably in real time but some delay acceptable)

I can connect to the Internet. I can not access gmail or yahoo mail. It doesn't matter what browser I use.
If I switch to a wired connection, I can access gmail. Other wireless networks work fine.
MY router is a Belkin N, but it allows me to access other sites. The settings seem pretty vanilla, not different than wireless routers where I can access gmail.

I've successfully set-up Drupal on my machine on a local network and have no problem accessing it with the virtual host names defined in /etc/hosts, but I don't have bind or any other DNS set-up.I've installed Postfix and can sent email with the mail command to unix account, and I can also read them with the mail command( from the command line).Now, my problem is with not being able to use the local Unix email accounts in drupal. Particularly, I would like to have one of the unix account receive email for the development site.I might like to also have various user on the drupal installation, and then test sending notifications to them.here is my /etc/postfix/main.cf# See /usr/share/postfix/main.cf.dist for a commented, more complete version

I have a simple system at home where a DSL router is used as a basic dhcp server with one port forward for ssh to a server. I need to allow my daughters, ages 14,12 and 10, to access the net and also email but I want to have complete control and logging. What I'm looking to do is set up the Ubuntu file server I already have on the network to act as a gateway and also add content management and logging as step one.
I also want to add an email server so that all the email comes into the Ubuntu server and then is allowed to be accessed by outlook on their machines after spam/content scanning for valid emails as step two. My question is what, if any, additional software do I need and what options do I have. I've played with dhcp servers at work but never got much beyond ip assignment and network booting so I'm unfamiliar with what is needed for content management and such. As to the email server I've never even played with this at all so I'm completely in the dark as to what I should be looking at to start with. I'm looking for directions, RTFM is fine but right now I'm not sure even WHAT manual/manuals I should be reading.

I've been on a quest to enable full routing through my openvpn tunnel between my office and the colo. Masquerading will work, however it will throw off anything key based and makes a lot of things just more difficult and vague in general. Is there an easy way to do this via iptables? I tried using quagga hoping it would magically solve my problems, however it does not seem to do my routing for me . I just did a basic static route within zebra...

I have three locations with a central office connected to two remote locations. At the central office I run on a cisco asa 5505 two site to site vpns. The remote end of the first site is a checkpoint firewall , and the remote end of the second site is racoon on debian. Both sites are up and working. However, where at the first site traffic goes both ways, at the second site it only works from the central office to the remote office.
For example, I can ssh from a host in the central office to a host in the first remote site (through checkpoint firewall,) then ssh back from that host at the remote office to any host in the central office. In contrast, after I ssh from a host in the central office to a host in the second remote office (through racoon), I cannot see the central office hosts (ping the ip address of a central office host, ssh, etc. all fail.) The vpn settings at the central office (the cisco asa 5505) are identical. So it seems to me that some routing magic is missing on the host running racoon at the second remote office. Where would such setting reside? racoon config files? iptables?

Have no idea what I am doing operating a server. Our programmer got a new job and I am the one who has to take it over. Everything was fine til yesterday. You see I made a control panel to easier update the site www(dot)discoverysound(dot)com
but yesterday when I went to update the site I got an error called fopen. I thought I fixed it (and boy did I ever) but now I cannot get to my site because it says Forbidden You don't have permission to access / on this server. Apache/2.0.47 (Unix) mod_ssl/2.0.47 OpenSSL/0.9.7a DAV/2 PHP/4.3.3RC4-dev Server at www(dot)discoverysound(dot)comPort 80.

I've got my username on Ubuntu (I can't remember version number, but its 6 months old aprox)..
I'm the sole user (& admin)..
I have /home/myusername/ & can edit all files (without using sudo), but if I want to edit a file in another directory - i need to use Sudo..
I'm setting up a website /home/website/
(this is the same structure as the external website I'm going to edit, i want the directory structure to be the same..)
is there a way, I can allow FULL access to the /home/website/ directory - While logged in as /myusername/
(IE So I do not need sudo (or any 'admin' command), to edit the files )

using fedora 9 i've problems getting bittorent to work. i have an external kerio firewall but my messages seem not to get thrue. I read about port forwarding, as a way to speed up bittorent I interprete that as bundling the port series 6881 till 6999 to ferdora:6881 so all the ports are channeld to the bittorent machine and 1 port.(tcp and Udp)
that how I did set it up, but i seem not to get a lot of throughput i guess Maybe 1kb per week, I do not know if this is what is seen as a slow bittorent.... on the firewall i see a lot of messages running arround but nothing seems to advance
what can I do, verify to get this running. (I temporarly switched off fedora's firewall( internal) is there a way to structuraly test bittorent? is my forwarding rule correct? (input multiple ports to single port?

I know, that this thread is old one, but I am having the same issue. It does not seem to me to be the problem of single torrent. It is more the way how much do I use my connection. If I have only 1-2 torrents, everything is ok. If I have 10, I get this problem. It is also followed by aprox. 30 secs of no internet connection. I use Deluge for downloading and my limits are set like this:
max connections: 200
max upload: 300 KiB/s
max upload slots: 5
max connection attempts per sec: 20
The connection outage is really annoying.

I am having a strange problem I've never encountered before. I have an Asus Eee S101 10.1" netbook with the 32GB SSD. I installed Ubuntu 10.04 Netbook Edition.
The other day, I was browsing with Firefox, when suddenly the entire computer came screeching to a halt. Had to power it down with the power button. After this happened, I have been unable to use the same Firefox profile I had been using. I had to start Firefox from the command line with the -ProfileManager switch, then create a new profile to keep browsing.
I wanted to completely get rid of the old profile, so from the Profile Manager I tried to delete the old one. Computer hung, had to reboot with the power switch. I then tried to browse to the .mozilla/firefox directory and delete the profile's directory there, from both Nautilus and the command line. Both times, the computer froze.
I tried a few more times, and the couple of times the computer didn't freeze, I got an error from the command line saying a Bash input/output error. After this error appeared, it would appear no matter what command I ran - I couldn't even run a sudo reboot now.
I can create/delete other files and directories, just not that Firefox profile.

I've done a search and tried a few things as follows,I can not access the Fedora project.org web site from home comp using either Unbuntu 11.04 and fire fox, or Windows 7 and I.E.all I get is can't acess site when it times out.Following a posting on this site i tried the command host fedoraproject.org the output i got was "none' rather than some IPs as the person posting got.I want to switch from unbuntu to Fedora because it is what Ken Mayer uses to illustrate in his Linux + vids and I've found Unbuntu does not contain all the commands.

I have Debian Lenny and I use Google Chrome for internet surfing. When I try to open a web page for any Microsoft site (microsoft dot com, msdn dot microsoft dot com, etc) it times out and never shows the page nor I get 404. All I get : "Waiting for www dot microsoft dot com" .
I have a Window XP VirtualBox machine within Debian with nic card as bridge and I can connect with no problems.
What could it be?. DNS look up addresses in Debian and Windows virtual are the same.

I have a problem accessing my site.
My Gateway, is using Ubuntu.
From ssh command, I can't ping it (and can't access it).
But, when I ssh to my client's gateway (different ISP), I can ping it (and can access it).
My admin says that it's the DNS problem in my Gateway but when I change the DNS on my computer, still the problem exists.

I tried Ubuntu, Kubuntu and now Xubuntu, all 11.04. I've also tried Deluge, Transmission and Ktorrent. With 10.10 everything worked fine (all variants). Also, in Windows 7 it's working fine. But now it drives me crazy. As soon as I start a torrent, the download starts but after 30 seconds or so the download drops to a zero. Also, I'm not able to browse anymore. The networkmanager tells me I still have a connection.
Some say it has something to do with the number of peers the client connects to, or it's my router. My router isn't the problem, as it's working fine with 10.10 and windows. So maybe it's the number of peers right? Question. Why can I connect with over 200 peers at the same time while I'm using 10.10 or windows, but can't do it with 11.04? Better put, what should I do to get this working fine again? Going back to 10.10?

first of all I am sorry about the mess in the question, I hope I am being clear enough.
I am using VectorLinux 6.0 standard, kernel 2.6.27.12.
iptables v1.4.0
Deluge v1.18
the problem is that as soon as I do
Code:
iptables -A INPUT -j DROP
Deluge hangs and stops responding.
I am trying to make iptables to drop everything except tcp,udp 6887 (for torrent) and except established and related. iptables -L looks like so:
[Code]...
Edit:
Now I see that Firefox also hangs if I try to right click a tab when I have iptables -A INPUT -j DROP.

I'm going away for the weekend and will only be able to bring my laptop that has the latest release of Ubuntu on it. My question is: will i be able to access my company's Terminal Server site [URL] from browser in Linux, and be able to launch the applications? (Outlook, etc.) Seems to connect to Windows Server 2008. If this works in Linux, that would make my life a lot easier..
