Ubuntu :: Can't Access Internet On Server Setup

Jul 8, 2011

First off - I'm running 11.04 as a VPS on an OpenVZ.

I've set up a very basic environment of LAMP + mail server. Installing apache, php, mysql and proftpd all went fine, but whenever I install iRedMail (which is postfix + dovecot + clamav and few more packages) I lose the internet connection.

Although the server is easily reachable by ssh and http, I can't connect anywhere from the server. At first I thought it only had issues with resolving domain names, but now I see it doesn't even ping IPs as well.

Code:
# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1

[Code]....

General :: PPPOE Server Access Internet Clients Fail To Access Internet

Aug 26, 2010

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?

Ubuntu Networking :: No Internet Access Via New Wireless Setup?

Feb 10, 2010

Running Ubuntu 9.10 Ive just got my wireless connection working after first having got the wired eth0 connection working.

With the wired connection I could SSH into my server through my firewall/router (via a forward). I can run up VNC, from there firefox, browse the web - all is well.

I have now setup the wireless connection, using a static IP, and I can likewise SSH into my server. I can run up VNC. I can ping my router. I can log onto it via VNC. I can browse to my router. But I cant browse the internet.

But I cant ping google.com. The reason is there is no host lookup service. Nslookup eventually says no servers could be reached.

So specifically, if I ping www.google.com Im told "unknown host". If I do an NSlookup on it I get timeout, no servers could be reached. However if I ping 66.102.11.104 I get responses.

I see no relevant entries in my firewall log.

Unfortunately I cant traceroute because the package isnt found - and of course I cant install it because I have no internet !

Strangely (to me at least !) if I then tunnel through SSH and browse the web, I have no problems. It works ? I know I am browsing through my SSH tunnel because whatsmyip gives the IP of my router at home, not where Ive SSHd in from. I can surf just fine.

why I cant do host lookups any more (and this did work with my wired connection, but whether its related to my change to wireless, or static IPs or both I cant be sure - it certainly appeared to happen at the same time). And, more to the point, what I need to look for/do to rectify it ?

As a bonus Id be interested in why I can SSH and browse via tunnelling but not direct from my server (via VNC). Just for interests sake !

if config reports :

wlan0 Link encap:Ethernet HWaddr 00:90:4b:27:ae:17
inet addr:192.168.1.69 Bcast:192.168.1.255 Mask:255.255.255.0

Ubuntu Networking :: Setup Server As A Wireless Access Point?

Apr 2, 2011

I'm trying to setup my ubuntu server as an access point but am running into some issues.

The server has an Atheros wireless card (AR5008 chipset) and I have used the following link to set it up in master mode using madwifi drivers: [URL]

I then used this link to set it upas an access point using hostapd. [URL]

But inspite of following the above steps, other wireless clients in my LAN are unable to see the ssid "Linuxmaster"

Although iwconfig shows that the card is in master mode.

iwconfig

Server :: Setup Permissions For SSH Access To Apache?

Feb 23, 2010

I am looking for the best way to set up permissions in the following situation. I have a web server set up on debian. I have different web sites in /var/www. Each web has a group of developers who each have system users and ssh access to the server. For example i have a web site in /var/www/example.com and a group of developers in group exampledev. I need all the users in exampledev plus the apache user (www-data) to have read write and execute permissions on all the content of the web site. I can give the group exampledev these permissions without a problem. The problem is that when they modify or create new files (they either connect via ssh o sftp which is the same right?) they are created with their user and group rather than exampledev. Am i going down the wrong path? This must be a common situation but i haven't found the solution.

Server :: Setup VSFTPD On Centos 5 To Access /var/www/ Directly

Sep 26, 2010

Trying to set up VSFTPD on the CentOS 5 box at work, which is an internal web development server. I'm leaving soon, and all knowledge of or desire to learn SSH is going with me so the other employees will need to be able to access the web root using FTP clients.

Essentially there is no need for special user accounts or privileges, it's an internal server in a tiny company. I've got the LocalRoot set to /var/www/ which I can log in to and read all files via FTP, however despite setting everything to 777 in /var/www/ and below, I still can't get any write privileges on the FTP server.

General :: Setup Media Server To Stream Video Via The Internet?

Nov 27, 2010

setup a media server in Linux which streams video over the internet? Is it easy to do this? I want a server that will actually encode video in real time to allow it to stream over sometimes slow or unreliable networks. Basically, I want a server that works on the internet. I have a directory with a bunch of video files, and want to make this accessible to myself remotely. For other situations, I found great and useful software (such as the PS3 media server). I'd like to find something equally as useful for streaming video over the internet.

Ubuntu Networking :: Get Internet Access To Server?

Jun 19, 2011

I have a server that was set up by a friend so I have a location to save all my documents for work in a RAID array.

It is on a static IP address, I can ping the hub and other computers on the network absolutely fine.

I can't connect to the internet, the router in question is a Netgear CG3101D. Logging into the router I can see that the server is a trusted device and in all the parameters are the same as other computer running Ubuntu Studio.

Does anyone have any tips of how I can find out how to find what is wrong?

It is Ubuntu 10.04.2 LTS (Lucid).

Networking :: Ubuntu Server Can't Access Internet ?

Jan 2, 2011

I'm setting up an old box as a dedicated file-sharing server on the LAN as well as an internet web server for my personal web site but I have no network connection. My computer is connected to a router which is connected to my DSL modem. The router has the Ubuntu box's MAC address as well as a Win7 box, which connects to the internet fine.

Here is what I've tried:

1. Check routing table

Code:

2. Try to add a default gateway to the internet on eth2, this happens:

Code:

3. I edited resolv.conf, which was empty, adding:

4. I edited /etc/network/interfaces as follows:

Code:

Then I type the following:

Code:

And it keeps doing this endlessly because it's not finding the DHCP server, presumably...? This didn't solve the problem and so I attempted another configuration:

Code:

Still, not internet connection and no ability to apt-get anything (says packages not found)

So, this didn't work either. What I've tried should work, especially the route command. Now why won't it work?

Ubuntu :: No Internet Access After Installing GUI On Server

I was having a hard time configuring ubuntu server with command line so this is the steps I did to install the GUI;

Code:

then

Code:

then

Code:

The GUI started up fine and I logged in as root, then I tried Update Manager and received this error message:

Requires installation of untrusted packages

I tried this in terminal window

Code:

and got

W: Failed to fetch [url]........(-5 - No address associated with hostname

So I did System Testing and got the result that my network was fine but my internet failed!

I could do command line update no problem before installing GUI. I can see it on the network on another computer though.

Trying to setup without the GUI is starting to look easier than with.

Security :: Setup Postfix On A Standalone Server Connected Directly To The Internet?

Jul 1, 2010

venturing into unfamiliar territory so I'm hoping someone can help me and make things a little more understandable for me. I have setup Postfix on a standalone server connected directly to the internet. I have got inbound and outbound email working for the most part, but I am worried about security.My fear is that if I leave port 25 open to the outside world spammers will find this and start relaying mail through it and eventually blacklisting the IP attached to this box.

For now, I am hosting mail for a single domain and single user (me) with a few aliases. I plan on expanding to IMAP and SMTP access from the outside at some point, but for now I've been using Mutt in a shell and it's fine for my needs for now.

Here are my current Postfix settings:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases

Ubuntu Networking :: VPN Server Does Not Allow Clients To Access Internet?

i have successfully setup PPTPD on my server and I can open a VPN tunnel but my clients can only ping the server's IP, they don't have access to the internet through the VPN.

i have searched different forums and understand that I have to create a route on the server to route packets between the VPN interface and my internet gateway, but I didn't manage to get this work.

here is what my setup looks like:

Server :: Local Dns Server With No Internet Access

Oct 1, 2009

In my computer networking class I have the option of doing a project where I set up a dns server for our classroom network. The problem is that this network is totally separate from the school network and we aren't allowed to connect it to the internet. I want all the machines to ping each other by name instead of ip using dns instead of host files on all 20 computers. I read on a site somewhere that you cannot do this because the dns queries will always go to the root servers. Is this correct? Is there some way I can do this using dns? The machine in question is using Ubuntu 9.04.
