Networking :: VPN Connections Fail On Ubuntu 10.0.4 / Solve This?
Aug 2, 2010
I 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.

I have a A7V8X-X motherboard with VT6102 [Rhine-II] on board network device. Internet connections work fine for long time on openSuse 10.3, 11.1 11.2 and 11.3. But since a few weeks ago, internet connections began to fail: several times when I want to open any Internet site with Firefox, it answers:

I installed Ubuntu on one of my machines a few days ago. It was an oldish CD containing 9.10. Eveything was puppies and rainbows. However, today I updated that machine to 10.04, and it no longer sees my network. Specifically, Windows doesn't see shares on it, and it doesn't see shares on Windows. Further, when trying to make a share (or rather update the one I had previously) I get the following:

Again, this is already the newest version.
And, being that I have no real idea what I'm doing, this is where my Googeling skills fail me. I want to reiterate, though, that before I updated today, networking was fine in both directions, i.e. from windows to ubuntu and from ubuntu to windows. How can I get networking to work again?

I can't connect to apache from outside the LAN. I can connect to everything else (ssh ftp) from outside.
I'm getting Error 101 (net::ERR_CONNECTION_RESET): Unknown error
My router is configured to redirect port 80 to my webserver. I am getting access logs etc and error logs for missing files (favicon)

What should i do? Is there any driver for it or any special configuration on the Mac Os X 10.4 and 10.5?

I'm a total NOOB and I just finished a dual boot Ubunutu Studio 9.10 64bit/Windows 7 x64 install on a brand new i7 PC using a WD10EARS hard drive (with the new Advanced Format) and I gave myself top marks for getting by the mammoth amount of obstacles to accomplish what I have so far.
Item of note: you can NOT do a complete install with Ubuntu Studio 9.10 using a wireless device. The installer ONLY recognizes motherboard ethernet ports. No worries, I moved it to the office and the LAN line and got a complete install. I am using this in my living room though as a Media PC with MythTV and the distance requires me to use WIRELESS.
After a successful install, I was unable to get my brand new, out of box Netgear WG111v3 to establish a successful connection and I need your help. Pardon the length of this post, I will try to organize it as best as I can but I have done a LOT of troubleshooting before posting here. Here's what I did so far:
1. Tested Wireless in Win7 on same PC. Works GREAT! Rebooted, went into Ubuntu Studio 9.10 and got no joy.
2. This page says the WG111v3 works out of box with Karmic and I can state with 100% certainty it does NOT.
3. Went to this page (which is THE best how to out there) and followed instructions. I discovered a bug in wpa_passphrase immediately. I use a very complex passphrase using !#$&@ characters in the mix. wpa_passphrase dies with various errors when it sees these characters because it thinks they're command items rather than part of the text in my key. Try it yourself. Create any long text string with those characters and input it to wpa_passphrase. It dies. Works fine with regular letters/numbers. I had to use this page to get the HEX value for my passphrase so I could complete my interfaces file. On a hunch, I changed my passphrase on the router to be a simple 10 letter word all in lower case. wpa_passphrase changed that to HEX fine, updated interfaces file, rebooted router and PC and got nothing. So it's NOT the passphrase.
4. Went to this page, which again states it works out of box but doesn't and tried all the help there. NO JOY.
5. Tried here too. The help there is good when combined with #2 above but still nothing.
6. Went to unsupported versions of Ubuntu to try some old school tricks. Got nothing.
7. Found this site and it has EXACTLY my problem! I always end up with "No working leases in persistent database - sleeping." when it tries to get an IP address from the router. As you can see, that user found no fix either.
8. I turned off ALL security on the router and left it wide open, updated my interfaces file appropriately, rebooted everything and it still couldn't connect?

Neither 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
# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in

Is 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?

I'm new to ubuntu and using 9.10. I have installed a dlink wua 2340 wireless adaptor and it is working properly. But after waking up computer by standby mode, wireless connection breaks and the wireless device is not mounted. Therefore I always have to shut down the computer and restart again to establish wireless connection.

I have a Dell Inspiron 1525. I am unable to connect to wireless networks. I have a fresh installation of Ubuntu 8.04. I have installed Ndiswrapper (ndiswrapper-utils_1.8-0ubuntu2_i386.deb) and the GUI for ndiswrapper. The ndiwrapper GUI reports that the hardware was not found. Yet I am able to connect to the wlan using Windows.

I recently did a clean install of Ubuntu 10.04 and tried using a DLink DWL-G122 dongle for a wireless connection.
It seems to connect to the wireless router, but I cannot seem to access any websites using the wireless connection. Ethernet connections to the computer work perfectly, but ethernet isn't ideal.

I'm unable to get my Ubuntu 10.04LTS to see my Mac 10.6.4 machine.
I've got Samba and AFP enabled under the Mac file sharing preferences.
Attempt1: From Ubuntu, I can see my Mac under Network>Places, but I'm unable to mount the location.
Attempt2: In Ubuntu, I went to Places>Connect to Server and entered the following:
Service: Windows Share
Server: [name of my mac]
Share: [name of my shared folder]
Folder:
User Name: [username]
Domain Name: WORKGROUP
With this entered, I was able to get as far as being prompted for my password, but was still unable to connect.
Attempt3: I followed the same steps above, but left Domain Name blank. Still nothing.
Are there any docs out there for the correct steps? I can only find posts on getting Mac to see Ubuntu, but not the other way around.

I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.

I tried installing the mac80211 framework on ubuntu 10.10 but after i install it and restart my system , none of my network connections work.
i found a solution to that problem which is a very weird solution. because none of the network connections are working . i try to activate the wireless driver from the System->Administration->Additional Drivers. But it fails , but after it fails my wired network connection comes back online. and then i have acccess to the internet . After that i activate the wireless driver again and it works.
This is obviously the worst possible solution ever. So what i don't understand is why the mac80211 framework is causing these problems. after applying my "solution" i thought of checking the modules installed on my system using lsmod and i see mac80211 there. i don't understand why it is still there after i executed the "sudo make uninstall" command . code...

I configured an internal fake ip 192.168.1.11 on a virtual interface of my server.
I'm running one of my postfix instances on this ip.
The problem is that postfix can't talk to external hosts on the internet when running from this internal ip 192.168.1.11
I get an error in the mail log
Feb 21 22:43:00 localhost postfix-R1/smtp[11372]: connect to 7zips.com[109.169.46.199]:25: Connection timed out
It works fine when I run postfix on real ips, but I need it to work from the internal.
I thought it should just work.
Am I missing anything?

I use Ubuntu 9.04 and try to get a Sweex LW053 USB wireless card (Ralink RT73/RT2500 chipset) to work. According to the Wiki list in the sticky thread, this one should work "out of the box" since 8.04.
lsusb delivers
Bus 002 Device 002: ID 148f:2573 Ralink Technology Corp. RT2501USB Wireless Adapter
and there is also some wlan0 entry that doesn't look too dodgy when typing ifconfig.
From this I get that my laptop recognizes the card.
I also typed in some numbers such as SSID and DNS server address in Preferences>Network Connections where asked (although the information that I had wasn't 100% what was asked for so I tried to guess what needs to be filled in which fields).
However, I don't get an internet connection (Firefox can't find server...)
What else do I have to (or can I) do?

I'm new to linux. I've just installed Ubuntu 11.04. It has all been going ok, but the wireless just stopped working all of a sudden. The indicator light turned off and when I tried to turn it back on (Fn+F2) nothing happens. Sometimes, when I restart the computer, the wireless might work; but if the signal is lost the LED on my laptop turns off and I cannot reconnect. Also, in these strange cases that the wireless works when I restart I can manually turn it off (Fn+F2), but nothing happens when I try to switch it back on.
In the menu on the upper right corner I see 'Enable Networking' is checked, but 'Enable Wireless' cannot be modified.
I have a Dell Inspiron 6400 and the wireless device is an Intel Pro/Wireless 3945ABG.
I have tried to follow some of the threads on this forum on similar cases, but the ones that were comprehensible to me did not work (or I actually might not have understood them either). code...

I'm on an Acer Aspire One.Clean install of 9.10.I was using 9.10 and my wireless was working fine.Then for no reason it would not connect.So I decided to reboot my router and reinstall ubuntu.Still does not work.I have figured out that it seems to be WPA encryption that is at fault.When I turn it off on my Linksys the netbook connects fine, turn it back on and nada.
if i try to use a static address then the laptop seems to connect but I cannot ping the router or get to the internet.If anyone has any ideas I would be grateful, I would rather use WPA than WEP.My iphone connects and this netbook connects with Windows, so I know the linksys is not at fault.

When 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.

I 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.

So 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?

Here 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:
[398598.251548] martian source 169.254.1.255 from 169.254.1.33, on dev eth1
[398598.251565] ll header: ff:ff:ff:ff:ff:ff:00:23:69:3d:b1:82:08:00
