Ubuntu Networking :: Unable To Connect To Internet Via Proxy Server With Apt-get
May 14, 2010
I am unable to connect to the Internet in lucid via a proxy server using apt-get or synaptic. Opera & firefox connects to the internet fine with the proxy setting.
I have tried the following solutions:
1) set proxy setting using systems|preferences|network proxy
2) editing ~/.bashrc & /etc/.bashrc
3) creating a /etc/apt/apt.conf file.
4) putting the proxy setting in synaptic
For the proxy setting I have used the both the verbose name as well as the ip address. There is no logon requirements for the proxy server. Either formats work in the browsers.

When I installed Ubuntu 11 Server, it asked for a proxy http address. I gave it our address, I'll call it a.b.c.d. It did not, however, prompt for the port number (8080). Now, when I do the following:
sreeve@pto:~$ !20
sudo apt-get update
0% [Connecting to a.b.c.d (a.b.c.d)] [Connecting to a.b.c.d (a.b.c.d)]
it just sits there for a while and then says:
unable to connect to a.b.c.d
Is there a way to give it a proxy http address with the port number also?

I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.

Is there a way to connect to a samba share on the other side of a dynamic ssh tunnel?I like to use ssh -D 8080 <host> to access the network on the other side of a ssh session. For applications with their own proxy settings it seem to work really nice.In this particular case I'd like to use the 'Connect to server' feature in Ubuntu to connect a samba share through the tunnel, but I can't figure out how to make only that connecton use proxy settings.If I enforce system wide proxy settings the ssh tunnel will die, so that is not an option.

Having a bit of an issue connecting to my apache2 server. I'm running Ubuntu Server 10.04lts. I can only connect to my website via ip address global, ip address local, and the dyndns domain I have linked to my ip address. I have DMZ setup for my server with a local static address of 192.168.1.100. I can only connect to the default apache page via lan, and It wont load when I try via proxy. I need to know how to configure my router (wndr3300) so that I can connect to my server (address 192.168.1.100) and the pages from outside of my network.

I used windows OS and installed Ubuntu 10.04 (amd64) in separate partition and works well but had a problem in internet connectivity. Likely reason may be the proxy setting that we used in college (currently). I used this commands to set up the IP address and gateway.
ifconfig -a | grep eth
"eth0"
sudo ifconfig eth0 192.168.5.209 netmask 255.255.255.0
[code]....
Then I manually set the proxy setting of HTTP which is given as proxy server 192.168.5.2 and port as 8000, further more there is a wins setting which is 192.168.1.178, really don't know where to put this number.

I am running Jaunty 9.0.4. I have go through a proxy to get out to the net. It was working. Sometime yesterday it was unable to resolve the proxy server. Can't even ping it. Other computers can. I even switch cables to no avail. What could block the proxy server? I can't even ping google.com Was it something I installed through add/remove software? Has anyone seen something like this before and even better has a solution or can offer a way to troubleshoot this? I can ping myself and the default gateway server.

I'm trying to set up a server for an NPO who connects to the Internet through an internal proxy (Websense). I can't access the Internet unless through the proxy.
Since it's a server I did not install a GUI so I'm wondering how to connect the new server to said proxy server. I have the IP address, port number and username-password for the proxy server. The new server has a static IP address and is ready too go!

Currently I have an Acer Aspire One netbook with Windows XP on it. I want to switch to Ubuntu, so I have the OS on a flash drive and I can run it fine. The only problem is,I cant see any wireless networks in range. I know the router is working because I can connect with Windows fine. A notification also pops up telling me i have to install missing drivers. But when i click on install, the progress gets to 99% and fails. It says i need the Broadcom B43 driver, but i don't know how to get it.

I've been trying for 3 days now, gone to a couple of ubuntu sites, asked some friends who unfortunately don't have the time to assist me, and gone through several forum responses on here to try to find the solution to my problem.The problem is my inability to connect to my wireless network. I have a linksys USB device for my wireless, and the wireless router is literally right next door to my room. I am able to find my router and my neighbor's router from my computer. However I can not connect to my router. It is WPA enabled, and I have the correct password. It is just unable to connect to the network, it tries for a few minutes then doesn't connect at all and says wireless network disconnected. I am currently hooked up to an unsecured wireless network, but I can't connect to the internet. I am using firefox, but it doesn't seem to connect to any site I try.
Here is the lspci
Code:
captain@The-Ship-Of-Capn-Alex:~$ lspci
00:00.0 Host bridge: VIA Technologies, Inc. VT8375 [KM266/KL266] Host Bridge
00:01.0 PCI bridge: VIA Technologies, Inc. VT8633 [Apollo Pro266 AGP]
[code]....
and when I ping I type in [URL] in the terminal and all that comes up is
Code:
ping: unknown host [URL]

I have been using Windows XP, and last month i had Linux Mint installed. I was connecting to the internet with an external modem and everything was running fine, until while experimenting with the settings,i bust the whole thing. What i did was to do a "right click" on the 'computer icon' at the bottom right-hand corner to disconnect and from that day i am unable to connect from Linux, but i can still do it under Windows.I had done the same thing under Windows but after going to the 'control panel/network settings' i managed to get the thing working.I went to the 'control panel' in Linux, and under 'network ' i get the message: "Auto eth0 => never". i have been trying to 'edit' the 'settings'

I have a multiboot system running several versions of linux which do not all use the same software for handling wifi connections or have the same kernel. They have all stopped being able to connect to the internet in the last few days. My Windows 7 set up still connects though it seems to be a slow to establish a connection.Could BT have changed something and if so what?

Am using Fedora 15, in which i was able to configure the proxy server and authentication. i confirmed this by configuring web broswer and it works. Now the problem is that i want to deploy it out to other computer system(client) i dont want to use the transparent proxy because the Proxy Authentication will not work.
I even tried to configure a DHCP server if it will work but i cant still configure for other computer system to work.

The server connects fine, I can load pages, FTP in, etc. So everything seems good on that end. When I try to use the internet from the Ubuntu box, however, it doesn't seem to want to connect. The internet won't load through firefox, and attempting to update through the repository won't connect. I've tried playing around with refreshing the connection and rebooting and such, but nothing seems to be fixing this. I can't think of what the issue may be as the connection is working, as I can get on the server, but can't seem to get it to connect outward from the actual box.
