Ubuntu Servers :: Desktop Has No Internet Access?
Aug 26, 2010
I have ubuntu server 10.04 installed with wired internet access through my router. I recently installed the ubuntu-desktop packages and cannot get internet through the gui, firefox never gets past the "looking up" stage.I can accessthe internet through the command line and through webmin httptunnel. Wget, apt-get install, apt-get update, apt-get upgrade all work fine from the command line. I have local access to the GUi as well in the form of VNC that is working fine.

My laptop is running Ubuntu 10.04. I have my own account (custom) and 1 desktop user account.
When I log in under my account and switch to the desktop user account, I can connect to the internet. However, if I start the laptop and log into the desktop user account first I get no internet connection and the same when I switch to my own (custom) account. What gives?

I've got VPN setup and working on my server. I can VPN into the server and access my local network from anywhere. It uses pptpd for it. My problem is that I can't access the internet once I'm connected to my VPN. Is it possible to allow internet access through VPN?I mainly would just like to be able to connect, access my local network, and still browse the internet. Is there anything specific I need to change?

I have ubuntu 10.04 running LAMP and proftpd, I can access over LAN but not when I type my domain name in. I have forwarded all necessary port to to the local ip of that box, added rules to ufw to allow traffic on those specific ports. I use dyndns for a second level domain and have used all their tools to check whether the ports are open and have the results I am looking for.

I am able to access phpmyadmin via my web browser using either my local ip followed by /phpmyadmin and by using the same layout with localhost. If i use my DNS name provided by no-ip which i bound to in apache2 i am able to get to the "It works!" page with the domain name but if i use /phpmyadmin after it, it will tell me that there is no such directory.

I've been searched for the related topic, but i couldn't found any of them. Basically, i want to set up a server to restrict internet access for other computer (windows box), but allow internet connection for kaspersky to download its database. Here are some questions:
1. Do i need two network card at the server box?
2. There are 8 computers but only 2 are allowed all internet connection, 6 of the rest are not allowed, all windows box can accept connection to download database from kaspersky.
3. Is it Iptables the best, easiest way to configure?

alright so i set up dhcp server and my clients are getting ip's, can ping each other, and can ping/ssh the server. but nowhere beyond that.
however if i ping an externel site, i get its IP addr, but no pings (100% loss)
im ripping my hair out over this. i know that iptables is right, but i dont know about dns
idk if this helps:
Code:
pavel@ubuntu-server:~$ cat /etc/network/interfaces
auto lo br0 eth0 eth1
iface lo inet loopback
#mapping hotplug

I must be very thick as i cannot seem to get my dhcp clients to connect to the Internet properly.
on my lucid server i installed dhcp3 server and bind9, i can ping and dig all on the local network. on the clients however, as soon as i go out of the local network there's messages like "unknown host www.google.com" or "network is unreachable".

I came back to see on the screen a message requesting remote desktop control. So I said no and went into remote desktop and said never allow connection. I had recently hosted a PHP app on the home pc for testing purposes using apache. Here are some of the last logs entries:

I'm a absolute "server- noob" but I've got some experienced with desktop linux and want to build my own file server to access my stuff over the internet. I'm using dropbox for a while now like a cloud drive by simply mounting the "private" folder (which I encrypted with encfs/BoxCrypt) in order to cross-platform use important files. The problem is that Dropbox only provides 2 GB for free and I don't know how secure my data is up there. Moreover I don't wanna always sync all files locally.
I got an intel atom machine standing around and so I want to build my own file server to provide the same or at least a similar service.
1. Which type of server application provides a "network drive" that computers (several users) from the internet can access?
2. What's the best way to encrypt my data and transmission in order to make the system absolutely unattackable/unreadable from outside?
3. Is there a service that can provide a dropbox-style sync mechanism?
4. Which distro should I use? I'd prefer a non-desktop enviroment solution but never had anything to do with it. Is that possible for an average linux user?
I'm aware that this solution won't be very fast because of the limited upload of a standard internet connection but that would be ok! It's more that I want to have the possibiltiy to access all my data as a thin-client anywhere, anytime on any machine and still be on the safe side. I know that this is some kind of contradiction but what would be the best compromise? I know some questions may sound stupid but I really never had anything to do with servers at all in the past...

I am currently finalizing a SSH Tunnel (gSTM) via Ubuntu Server (see: [URL]). The gentleman who helped me there went above and beyond the call of duty as we used to say in the military. Accordingly, I wanted to start a new thread to explore options to the pending completion. So, several systems in play here. I will list two of the three with the presumption that the SSH situation is in play (testing it today from outside of my network).
Systems Currently in Play: Ubuntu 10.04 Desktop Edition with all updates as of today's post: Server: Acer Aspire AST180-400A. It is currently being accessed from Ubuntu 10.04 Desktop Edition with all updates as of today's post from a laptop: Toshiba Satellite A200. Router: Netgear N300 WNR 2000v2. Modem is Motorola Netopia 2210-02-1006. Proposed System To Add: eMachine ET1331G-05w running Windows 7. Why? Well, my girlfriend is terrified to ditch the Bill Hates way of things. It is running through the router currently as well.
What I would like to be able to do is access the Windows 7 desktop via my laptop on the road as well. Specifically, I need to be able to access and view documents and photos. Now, the docs are at least in OpenOffice; she switched to it finally. I would like to also be able to view my desktop to access docs and pictures on the server, but that may be a new thread as the Win7 situation is the priority right now.

I just finished setting up my small server, however I realized that no one can connect to it from the outside. The reason being is that my router is assigning internal ip's and dyndns is linked to that. I need port 80 for the Apache server, but if I have the router forward that port to my particular ip, won't it screw with everyone else's internet too?

Ever need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.
While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)
But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.
So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.
So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.

I have a machine (lets called it machine 1) with two networks card, eth0 and eth1. Both have static IPs. Once in a while the machine refuses to give access to the Internet via Firefox (eth0 is the route to router). Other machines on the network have no problems accessing the Internet. Eventually the machine would just magically start working again, but this time it just seems to have stayed broken. I've done some simple diagnostics and found:
a) I have another machine running Apache with a Wiki on our network - [URL]. Machine 1 is unable to connect to this Wiki. I get 'the connection has timed out'. I can ping 192.168.1.73 and it responds in the usual fashion.
b) If I try to ping www.google.com it times out with: ping: unknown host www.google.com. I can ping google using its IP address.
c) On machine 1 I have tried traceroute on both www.google.com and its IP and I just get:
1 * * *
2 * * *
And so on until hop 30. Doing this on any other machine on the network works. So while it seems I can ping internally in our network and outside, but when it attempts anything traceroute or URL related it does not work.

I am a novice in the world of cloud and recently managed to configure Ubuntu 9.04 Cloud (using kvm, eucalyptus and other packages) successfully at my college for my project work. The problem is that i can only manage to view the running instance using rdesktop from any remote machine. Is there any way to do this other than rdesktop/logs? Secondly, I want to develop a application on the lines of google docs as a part of my project. Is it possible to install apache server on this virtual instance, and host a website? How will the client access this website? Which frameworks would be required or do I have to develop one?

Is there any way to install a Ubuntu server and access the server remotely via a Ubuntu desktop environment instead of a SSH command line?
I will be installing a Ubuntu server in an office where the office manager will need to be able to do simple things like add/remove users, access filesystems, etc. She can handle these tasks in Ubuntu desktop/GUI, but it is impractical for her to have to learn how to use the CLI terminal to do this stuff.
Will I have to install desktop Ubuntu on the server to do this, or can I install Ubuntu server version and setup another computer Ubuntu desktop to remotely login graphically?

I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?

I'm not really a newbee in Linux but I am a newbee in networking. I have both a Ubuntu laptop and a Gentoo desktop computer. I have just bought me the MBR1000 Cradlepoint router and it works great with my Verizon USB 760 modem plugged in it. I can now send and receive email on my Ubuntu laptop. I like it.My Gentoo desktop computer is just sitting there with no Internet access because my Verizon modem is no longer plugged into it but plugged into the router instead. Only my laptop now has Internet access. The laptop has an integrated wireless card built in the MB but my desktop has no such capability.
Is there a way (besides buying a wi-fi adapter) to get Internet access on my desktop computer through networking so that the router would give both computers Internet access at the same? My Gentoo desktop does have an ethernet adapter that perhaps I could useThe router has several LAN ports and one WAN port, both unused.

Running Ubuntu 9.10. In the Remote Desktop config dialog I get: "Your desktop is only reachable over the local network. Others can access your computer using the address 127.0.0.1 or tabatha.local." I understand this means only the loopback ip address is available. All my other machines show their true local ip address (e.g., 192.168.1.104) in this dialog. Thus I cannot log on to this desktop from other machines.
When I try to do a remote logon from another Ubuntu 9.10 box (or from an XP box using a VNC viewer), I get: "Connection to 192.168.1.102 has been closed." What steps are needed to make this machine show its actual ip address? All file sharing between the various machines is working properly and all windows shares back and forth between XP and 'nix, and among the the vaious XP boxes and linux boxes are available as designed.

I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection

I can't remotely access my desktop when the desktop is asking for a keyring password. Why does this happen? it means that remote access is useless because you would need to enter the password locally before you can vnc to it. I do not wish to disable the default keyring but is there a way of making vnc work so I can enter the password.

I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message
- download (curl) error for (repo)
- error code connection failed
- error message could not resolve host (repo)
This was followed by a message box containing
- UI syntax error
- no widget with ID 'contents
Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)

I have an old FC2 box running Squid version 2.5. It has been running since 2003 so I am in the process of replacing it. I have a new machine with FC11, iptables, and Squid 3.0 installed.
On the old machine I use iptables to intercept Port 80 traffic and send it to Squid. By default I block all internet access and allow only sites that are in an Allowed_Sites.txt file. Within Squid I also have statements to allow certain users to bypass Squid based on their IP address.
I have set up the same thing on the new box. I have iptables intercepting the Port 80 traffic and sending it to Squid. That is working because if I remove the redirect statement from iptables all internet access is blocked.
The problem I am having is that Squid is not blocking any websites. It acts like the ACL is set to http_access allow all. I have worked on this for several hours and am stumped.
These are my Squid rules:
acl allowed_sites url_regex "/etc/squid/Allowed_Sites.txt"
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32
acl SSL_ports port 443
acl CONNECT method CONNECT
http_access allow manager localhost
http_access deny manager
http_access allow Bypass_Users
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
acl our_networks src 192.168.1.0/24
http_access allow allowed_sites
http_access allow our_networks

OpenSuse 11.4 Asus Netbook 1000H Following other members in the forums I have installed Opensuse 11.4 on the Netbook. In the early days Ubuntu Netbook Remix worked well for me. But this has been discarded, and the "one size fits all" Ubuntu had become slow and cumbersome. So..... onto my post. Opensuse is working well. The install went beautifully.
It detected the Wireless Internet and I am able to get on line. I also need to share the Internet connection to a desktop. This is done via a small network switch. Thus far I cannot do this. I tried to use ifup to configure a static ip but this busted my Wireless configuration. I went back to knetwork manager. Then I tried to set up the wired network using knetwork manager and under IPV4 "share" the connection. But this blanks out any possiblity of a static address and substitutes dhcp. My desktop cannot ping the this dhcp address. Ubuntu had this thing called Firestarter? - from memory. This configured the system to sharing the network.

I'm having a problem with my webdav share. I have a secure webdav folder that gets accessed via a non-standard port and requires basic authentication. I can connect and interact with it fine via cadaver. However, when I try to connect from nautilus, it says "Access was denied." To make it even stranger, sometimes I can click on the folder in nautilus (it still mounts) and access it. Sometimes not (just repeats the error message and won't show me the contents). I may not even un-mount it, but just look at other folder, then click it again and be able to access it, but again - only rarely.
I asked a friend to try connecting from his windows vista computer and it would not work. It would not work from my windows XP virtual computer either. However, it mounts and works just find from my work computer (also Windows XP).
So it seems to be a 50/50 chance that the drive will mount on any given computer/system and work. Do anyone know what the problem may be? I'm guessing user permissions, but I can't figure out what.
I've made sure the webdav folder is owned by www-data and www-data has read access to the password file as well.
When I try connecting from nautilus, I get this in the log file:

Here is one of the (many) sites I've tried looking at: [url]
