Ubuntu Networking :: In VMWare - Unable To Connect To External Sites

Apr 12, 2010

Have just installed Ubuntu 9.10 in Vmware workstation 6.5.1 and unable to connect to external sites, or servers (using NAT). I can ping on host name and IP but can't resolve either host or IP in browser (Receive message the connection has timed out). I can't ping the host (Windows 7 Professional) IP from the guest and vice versa. I use a mobile wireless network card, and my Windows operating systems work successfully in vmware. Currently in my VMNet8 properties I just have Obtain IP address and DNS Automatically (same as host).

Ubuntu Networking :: Can't Access External Sites

Sep 1, 2011

Strangest thing...yesterday my 11.04 box lost the ability to access anything external. I can ssh to the box from outside my network, and all other boxes on my network are fine, but this one box can't hit anything external. If I attempt to ping a site it's doing the same resolution, but no packets are delivered.

Up until yesterday it was running fine, and I didn't make any changes to my home network or install any updates. Totally stumped.

Edit: this is a wired connection with a static internal IP.

Networking :: New ISP Can Connect To Only A Few Sites?

Feb 2, 2009

I have an odd Linux problem. Changed ISP recently -- Windows NT4 & W95 work fine. Linux has worked fine on previous ISPs, but on the newest ISP, I can connect successfully on Linux, but can only communicate w/maybe one out of 10 sites (Google, for ex.). Mostly I get "cannot connect to site". Some points:

-Linux is Slackware w/kernel build 2.4.26.
-No settings changed from Linux setup that worked fine on previous ISPs.
-/var/log/Log file says PPP connects via CHAP successfully & no problems..
-I don't see any similarity on the few sites I can connect to -- seems random.
-ISP is useless -- say they "don't support Linux".
-Using Firefox & Konqueror browsers.

Ubuntu Networking :: Internet - Cannot Connect - But Can Connect Through XP On VMware

Aug 15, 2010

I had put my computer on standby and when i restarted it, it powered off within a few seconds. I turned it back on and after that i've lost connectivity to internet on Ubuntu 10.04.

However I have VMware (XP) installed and internet/network works on that. I'm a newbie with Linux.

Here are some outputs:

I have tried to edit the connection using System>Preferences>Network Connections. I entered manual settings for IPV4, but whatever i enter there, it doesnt get reflected when i type ifconfig in the terminal window. I tried setting it to Automatic DHCP as well. Doesnt work.

Ubuntu Networking :: Wireless Can Connect - Can't Open Sites/IPs

Jan 20, 2011

I've installed 10.10 yesterday on my old HP Pavillion ze2000 as dual boot with windowsXP and the wireless was working normally, I've updated everything it asked to update, rebooted a few times due to some of the updates. Today when I turned it on it was connecting normally to the router, though when I opened mozilla or tried to ping the router IP on the network tools neither have worked. Couldn't open any site on mozilla or ping any ip although it says I'm connected to my wireless router as it would normally. When I open into the XP my firefox there works just fine.

Ubuntu Networking :: Can't Connect To Internet At Sites Requiring Sign-in?

Nov 16, 2010

DM9, 2GB RAM, 32GB SSD, Ubuntu 10.04 UNR.At Panera and at my local library there is a page that comes up when I try to connect to the Internet that is an agreement page. It comes up with my iPod Touch and with my MacBook. Using my DM9 that page does not come up for me to sign in so I can't get on the Internet.I have had Firefox and Chromium running at different times with the same results. When there is a WEP password or no password it connects. What do I need to do to get connected to the Internet at Panera and the like?

Ubuntu Networking :: Can't Connect To Sites Served From Amazon's EC2 Cloud

Apr 8, 2011

Over the last 3 or 4 days, I have been unable to load sites that serve their images, scripts and whathaveyou from Amazon's cloudfront domain.

[URL]

I have made no changes to any of my networking files, hosts{allow,deny}, or dns settings.

Connections don't provide any errors, just continually fail to load. Stopping the page load after a while reveals the raw HTML in some cases (quora and blekko).

Tested in Firefox, Chromium, Midori and Vimprobable.

I have booted into another distro and pages resolve immediately.

I have disabled IPV6 and my firewall - to no effect.

Networking :: Easiest Way To Redirect External Traffic To VMWare Web Host On Same Machine?

Jul 14, 2009

Have done a bit of Googling around this but got totally swamped so will try here. Basically we are running a CentOS server which hosts a number of virtual hosts under Apache. Recently I needed to set up a development environment for another site using Ubuntu and have this running and accessible on the LAN from a VMWare image. I'm using bridged networking so the VMWare machine has its own IP on the LAN subnet.

I've set up a DNS to point to the external IP of the physical host but can't figure out how to route traffic requested on this domain to the VMWare host. I've basically tried two approaches (configuring a proxy web server and reverse proxy in an httpd.conf file and mucking around with iptables forwarding rules but without success.

Ideally I'd like somesite.somewhere.com to point to the VMWare IP but I could live with a custom port on the end if thats whats required.

To throw further complication into the mix I need reliable communication between the VMWare machine and external mail relay servers in order to debug any issues with mail bouncebacks, embargos etc.

Any idea what's the easiest way to accomplish this?

Ubuntu :: Unable To Connect An External Monitor To Laptop Running 10.04?

May 13, 2010

I've been unable to connect an external monitor to my laptop running 10.04, even though the resolution and framerate are right. The monitor says something like "unsupported video settings".

In other news, I put the live cd into another computer which relies on a monitor and after the very first screen with the two logos at the bottom, the monitor decides to go to sleep. I try with another monitor and it just seems to have to feed. This is the more important problem, but I wonder if there isn't some built-in problem with 10.04.

Networking :: Connect VMWare Guest To Host?

Sep 14, 2010

I have VMWare on a notebook, guest Windows running on Linux host. The network in that virtual machine is configured as NAT. I want to share/transfer files from Linux (host) to Windows (guest). So I leave sshd always running on the notebook, I go into Windows and run an SSH/SFTP program. My Wifi router has address 192.168.1.1, my desktop has address 192.168.1.2 and my notebook has address 192.168.1.3. On the notebook, that SSH/SFTP program connects to 192.168.1.3 (i.e. the notebook itself) and everything works fine. But it's a notebook, and when I leave home with it, 192.168.1.3 is no longer accessible. How can I let the guest OS connect to the host OS when I'm away from my Wifi network?

Ubuntu Networking :: Connect To Server When VMware Is Running Windows?

Jan 15, 2011

I have a private server which I stream media from, but since I've installed VMware running Windows 7 and set up Windows to used a bridged connection, so I can access the network drives in Windows. Now that I have done that, I cannot connect to my home server unless I have VMware running.

I only want windows running when I need it, but I need access to my server at all times.

Ubuntu Networking :: The Phone Can Access The Internet Through The Computer Unable To Get Access To Https Sites, Like Webmails

Dec 31, 2010

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

Ubuntu Networking :: Unable To See Local Web Sites From Local Network

Jun 28, 2011

I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).

Ubuntu Networking :: Unable To Connect To The Internet But Can Connect To The Router

Apr 6, 2011

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.

Ubuntu Networking :: OpenVPN Only Connect When External?

Apr 26, 2010

We use Openvpn for remote access to the office network. It would be nice to keep this running and automatically connect to the office at all times.Once started, it does this anyway. The problem lies when the user comes into the office. Openvpn connects as usual to the vpn gateway, but this causes weird routing loops.Is there a way to say to Openvpn "Always connect to the gateway unless you are on network 10.10.10.0/24" ?

General :: Using Wget To Mirror A Website And Everything From The First Level Of External Sites

Sep 14, 2010

I need to mirror a particular website (all the pages under that particular domain) any pages (but not whole sites) that the website links to.

How to do this

wget -r --level=inf (or some other variant) will mirror the site.

wget -r -H --level=1 will get all the links (from all domains) to the first level.

Anyone have any ideas on how I could combine these, to get the entire of the main site and one level deep into external sites. I've been banging my head against the manual all afternoon.

Fedora Networking :: Connected To Router - Can't Load Sites - Can Load Sites In XP ?

Jan 14, 2011

I dual boot XP and FC14 and have 2 routers. I can connect and ping one of these routers when I'm in FC and I have an IP address I just can't load any websites. When I connect to the other router (my main router) it works fine. When I boot into XP and connect to the problem router I can load pages fine. It's only when I'm on FC14 and connect to the problem router that I can't load pages even though I have an IP and can ping around.

Fedora Networking :: Unable To Connect To Wireless Networks And Unable To Configure Network

Jul 27, 2010

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.

Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network

However, there is no Network option under System>Administration.

Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

Networking :: Connect To External Computer Using Local Address?

Apr 9, 2011

I couldn't find an answer to this question (not including vpn) on different threads so decided to eventually post it, though it's probably easy one. I would like to connect to some application on known IP and port in the internet from my LAN computer. However to do so (I have some application, not any administrative constraints or not being allowed to) I would like to use local addresses. So, let's say - I want to connect to the external host VV.XX.YY.ZZ, port AA using 192.168.EE.FF port BB. Baically so far I have limitation in my application (too many places for possible error, to correct it right now - will change it in future). Is it possible that after my application sends request to 192.168.1.EE port BB, my Linux transparently translates it to VV.XX.YY.ZZ:AA? I tried iptables tutorials and some forums, but nothing seems to be addressing this issue. I don't know if it's event possible with iptables but am pretty sure this should be possible.

Networking :: Ubuntu Server Cant Ping Or Connect External / Can Resolve Hostname And Domain

Oct 15, 2009

As the title suggest, I have downlaoded the latest copy of Ubuntu Server from the ubuntu website.Everything installed fine. DHCP configured ok as far as I can tell. I can ping other machines on my network (which are running Windows) and they can ping the Ubuntu machine and conenct to Apache which is running on it.If I try to ping google.com or any other domain, it gives the correct IP address but gives no response to any pings, dont telnet on port 80 (or any toher potr for that matter) on any machine on the internet. I checked the settings using ifconfig to see what DHCP had assigned, and they matched the windows machines configuration (other than the IP address obvisouly). I tried assigning a static IP, even reserving a particular IP for my NIC.

Whatever I do, i cant connect to any machine outside the network via IP or domain.I have searched everywhere and tried everything i can find on the net but still to no avail.The Windows machines are part of a domain called alcom-uk.local and run off of a Windows Small Business 2003 Server. Not sure if i need to manually setup Ubuntu to connect using a domain or anything.
