Ubuntu Networking :: Missing Connections Tab In GUI?
Jul 27, 2010I have recently installed lucid 10.04, and I am having difficulty accessing my wireless. Following instructions to install the drivers for my wireless card, I always run into a problem when I need to configure my card. When I go to system-administration-network, there is no connections tab listed. I can only access General, DNS and hosts.

Aug 23, 2010Neither of my wired network connections are listed in the network manager applet. I know that networking seems to be functional since I can ping local devices on the network. I can't resolve DNS names however. I suppose this is because network manager usually handles DNS? I've posted the outputs of various configurations below.
Code:
/etc/NetworkManager/nm-system-settings.cfg

Security :: Policy That Limits Connections On Port - Encapsulates Total Sum Of All Connections From Hosts?
Jan 21, 2011Is 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 5 Replies View RelatedUbuntu Networking :: Connections Not Showing Up?
Jan 12, 2010When I click on the network manager icon next to the date in the upper right corner of my screen, my network connections do not show up. I have added two DSL connections on my laptop (username & password) but it doesn't show up. Everyday I need to use
Code:
sudo pppoeconf
if I wish to connect to the internet.
Both these connections are added in the same way on my Desktop Computer and it shows up on the network manager. One of them is even the default which connects automatically on startup.
Because it's not working I assume network manager is not compatible with my laptop. Are there patches to install or other programs that can easily manage my internet connection?
I'm using Ubuntu 9.10 on a not-so-new laptop.
Ubuntu Networking :: Opendns - All Connections Rather Than 1 By 1?
Nov 14, 2010So I'm going to try out opendns as an internet filter. But I'm not doing it on a network/router, just on my local machine. Using ubuntu, I read that I need to select each connection and change the dns settings.Is there a way to generically add the dns settings so that if I connect to a new network I don't have to manually update it's settings?

Jan 30, 2010Here is the layout of my network:My cable modem plugs into eth0 on my ubuntu server which acts as a firewall (shorewall) and dhcp server to my lan. A dd-wrt access point is plugged into eth1 and then a bridge connecting my xbox360 and another bridge connecting a desktop computer.Everything works pretty well, except a few times a day, my network will just shut down. The wireless on my macbook and my wife's laptop will just shut down, and if my xbox is running, it will lose connectivity. It will be down for maybe a minute or two, and then come back up like nothing ever happened.I never had this problem when I had just a dd-wrt router running everything instead of my server.When I ssh into my server afterwards and run dmesg, this is what I will get:
Code:

Ubuntu Networking :: Monitor Internet Connections ?
Jun 7, 2010I am a user of Ubuntu 10.04 and I use Firestarter because it lets me know which IPs I am connected to, which ports are used, and which applications are using those ports. The problem is that I can't use Firestarter with my non-sudo account (well, I know that I can change my system settings to do that, but I'd rahther not do it).
So the question is: Is there any application that lets the user monitor the internet connection?
Ubuntu Networking :: Use Of The TSC For Remote Desktop Connections?
Jun 17, 2010Alrighty, I have a couple of questions regarding use of the TSC for remote desktop connections. I'm connecting from my Ubuntu Desktop (Lucid) and i'm connecting to my Laptop (Windows 7) i'm running PC Tools Firewall Plus on the windows machine. The window's machine has remote assistance allowed. At the moment i'm just trying to get the TSC to work on my home network. I filled it out as follows:
Computer: Lappy's IP
Protocol: RDPv5
Username: ZachAdmin
Password: *My password*
Domain: Blank
Client Hostname: Blank
Now the first time I tried to connect, about 20ish seconds passed and "The connection has timed out" appears. So I went into my Firewall and sure enough it was blocking the UDP/TCP packets that my desktop was sending. So I temporarily allowed all UDP/TCP packets. Now when I connect "Connection Refused" immediately pops up. I go into my firewall and it's allowed both inbound and outbound packets from my laptop to my desktop and vis versa. So now i'm really stumped.
Ubuntu Networking :: How To Forward Transmission Connections
Jul 17, 2010Now I know how to set up port forwarding on a router so this is not that. What I want to do is, if possible, connect from Computer A to computer B and use computer B as a proxy for all of the Transmission (bit torrent) connections. I know how to do this with DNS, Http, etc etc but I'm not quite sure how to go at this with torrenting.Note that in this case Computer B is a ubuntu 10.04 server with an SSH server but no torrenting program installed.

View 1 Replies View RelatedUbuntu Networking :: How To Enable Loopback Connections
Aug 22, 2010I run a webserver Apache2, php5, and MySQL. They are all set up correctly and I can access my website at [URL] I have, also installed, noip2 to update my IP address to no-ip.com for my domain name. Here's the problem: I can access my website through that domain name on other computers, both on internet and on the same network. But I cannot access it from my own computer (using the domain name instead of localhost). I need to be able to access the domain name on my computer because some pages on my website have been defined as the address to my domain name and not localhost. I cannot change this to localhost because if I do then people outside cannot work the webpages correctly. I had the same troubles on Windows before and I simply enabled loopback connections by typing in my private IP address along with the domain name into the Windows hosts file. I use version 10.04.

Ubuntu Networking :: Wireless Connections Not Found
Nov 10, 2010I have an Acer AspireOne D255 netbook. I just installed Ubuntu Netbook Remix 10.10 and it looks pretty sweet.Right now, I'm on a wired connection. It's not detecting any networks, and I know at least my home wifi should show up (and usually we can get onto our neighbors!)I used to have a different model of an AspireOne (I think it was 531h but I'm not 100% sure) with UNR 10.04, and my network was detected right out of the box.
This reminds me of when I installed the desktop version of 10.04 on my iMac. I couldn't bring the wired connection to the room it was in, and my wifi didn't show up on it. I just gave up because I like my Mac so it wasn't a *huge* deal. but I definitely don't want to use this stupid Windows 7 Starter that comes on this netbook!
Ubuntu Networking :: Ufw Blocks IPv6 Connections?
Jan 10, 2011I've just started using ufw with the frontend gufw. I've configured it like this:
Accept everything in and out as default Block incoming FTP connections from a certain IPv4 address (brute-force for days)
Today I noticed that IPv6 connections don't work anymore. The connection to two hosts (IPv6 only) times out. As soon as I disable ufw entirely, the connections work again. The host I want to connect to is:
2001:638:a00:f00b:200:1cff:fedb:d38f port 7337
2001:638:a00:f00b:a00:6ff:fe07:cda2 port 7337
These are small telnet servers that print out a number (temperature nearby) and close again. I'm logging those values in a database.
Is ufw not IPv6-capable and blocks things it's not supposed to?
Update: ufw seems complete garbage to me... You can't even configure it while it's disabled! How am I supposed to safely activate it when the first thing it does is blocking all communications? I can't even configure it to let me in before I configure it to keep me out... And then, even if I explicitly let it pass port 7337, it still blocks it through IPv6.

View 1 Replies View RelatedUbuntu Networking :: Getting Two Connections To Play Nicely Together?
Jun 12, 2011Is there any way to turn off the load balancing that occurs when ubuntu detects two active network connections? To be more specific, I have two networks set up, one of which is supposed to be for regular web traffic while the other network is dedicated to streaming various things throughout the house. Whenever I try to connect my server to both networks at once ubuntu "load balances" traffic from the web network onto the streaming network, which completely defeats the segregation I was going for. So far all of my attempts to turn off that behavior haven't worked at all. I'm currently running Ubuntu 10.10.
View 3 Replies View RelatedUbuntu Networking :: Wireless N Dropped Connections
Jul 4, 2011I'm working right now with ubuntu 11.04 on my asus ul30vt-x1, my wireless n network is working on a linksys e3000 router, my issue is basically with long file transfers. When the issue started i was reaching speeds of 100 Mbps through my wireless network even when I'm connected at 150 Mbps. However when at this speed, I don't know why, the connection is dropped after some minutes or even seconds. I made some testing on windows, I'm reaching 70 Mbps there and no problem at all with dropping the connection.
So my conclusion is that for some reason the linux driver, in my case, is not able to handle such speed of 100 Mbps. I know that a wireless network will have a throughput of aprox 60% the wireless speed. Right now im trying to apply traffic shapping to my transfers so i can get 70 to 80 Mbps, its being working so far.

Networking :: VPN Connections Fail On Ubuntu 10.0.4 / Solve This?
Aug 2, 2010I am trying to find someone that can perhaps assist me with the following.
I have installed my notebook with Ubuntu 10.0.4 and need to setup various VPN connections to clients.
After setting up the microsoft VPN connections according to the normal procedures, I try to connect to one of the clients to test connectivity, but the connection fails.
This happens for all the MS vpn's so far.
I had a look at the daemon.log file and found the following message which I can't seem to find a solution to:
<WARN> connection_state_changed(): Could not process the request because no VPN connection was active.
Is there anyone that could perhpas assist me with this as I am not able to work without VPN.
