Fedora Networking :: Failure Connecting VPN To Corp Network ?
Jan 12, 2011
I am running fedora 14 and have tried to setup VPN access to work. I used the simple networking GUI program. Another engineer at work uses ubuntu and that is how he accesses the VPN. I think that I did everything right but get this generic 'VPN connection failed' message. I am trying to connect to a monowall firewall and have the IP address. Yes, I have an account but am just trying it for the first time. I turned on all of the options available which seemed correct based on the instructions that I had. I have contacted my sys-admin to try to find out what the monowall doesn't like. However, I am wondering if I might need to open an outgoing port on my linksys home router/firewall and, if so, which one?

Currently my office use a Cisco Firewall which will only allow the ANYCONNECT utility to do the vpn connection. I found a Linux utility (OpenConnect) which will do the same thing, but allow me more flexibility with my networking needs.What I ultimately would like to have is to have a switch that I can connect any network device into it and be connected to the office. IE (my IP Work Phone and Computer) Currently I have is a computer with fedora 13 and two network cards eth0 (home network - connected to a router) and eth1 which I would like to connect a switch to. OpenConnect communicates fine and I can see the work network from the Fedora machine. It creates a vpn0 tun/tap device and I don't know how to pass communication to/from the eth1 device.
Do I try to iptables the ports for the phone and services I need on the computer? Or do I build bridge; and If I do what am I bridging. I have tried making a bridge from eth1 to vpn0 which reply's with unsupported device or something like that.Unfortunately my network skills are bit limited and my office says "it can't be done". Their solution is for me to buy a ASA5505 (or something device) and have a static IP. I would have to make it work as my router and even then it will only DHCP 10 ip addresses; which will cause a shortage of IP addresses in the house.

I'm attempting to get 10.04 to connect to an SBS 2003 pptp vpn server, but for the life of me have been unable to find or implement a working solution. System previously had 8.x and 9.x and had no difficulty connecting to same server, but on a fresh install of 10.04 cannot connect.
tail -f /var/log/syslog shows the following:
Code:
Sep 10 15:19:32 ubuntu NetworkManager: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'...
Sep 10 15:19:32 ubuntu NetworkManager: <info> VPN service 'org.freedesktop.NetworkManager.pptp' started

moved to Fedora 11 but can't figure out how to get my wireless working. I have the broadcom driver installed and the Network Manager Applet shows the available wireless networks, but when I click on them they just don't connect.I get the following output on lspci regarding the wireless adapter:03:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 02)

I'm having problems with my wireless card. The network manager won't allow me to turn it on. It is working in windows and in ubuntu, but I can't get it to turn on under fedora. I'm using a Lenovo B570 laptop and it uses the Centrino Wireless-N 1000 for wireless.

Decided to upgrade my usb bluetooth dongle because it is slow, old and bulky. Bought a Konig (broadcom) mini dongle. Ubuntu (natty) shows me a bluetooth icon and appears to be working. But: It doesn't find anything, nor can it be found...

I have an IBM ThinkPad W700 running 64 bit Ubuntu 9.10 Karmic Koala. At the office I normally connect it to the Ethernet since it's never connected very reliably to the wifi there (drops out 2 or 3 times per day, usually at the worst possible time, of course), but it always worked just fine with Netgear WGR614v5 at home... until a week or two ago.
I used to be able to come home, take the laptop out of suspend mode, and it would connect to the wifi. Occasionally there'd be some hitch and I'd have to restart the network manager (sudo /etc/init.d/network-manager restart) but this was only sometimes, and when I did, it'd always work. But now, when I get home from work, I need to restart the entire system to get it to connect properly again. Without restarting the whole system, it either doesn't scan for wifi networks, it doesn't find any wifi networks, it keeps stuffing up my wifi password, or it connects and gets 0% signal.
Presumably, some driver was updated recently and it doesn't work so well. What's the easiest way to find out what drivers have been updated lately, and revert to a previous version? And what else can I try restarting so I don't have to restart the entire system? I've tried /etc/init.d/network-manager restart, /etc/init.d/networking restart, /etc/init.d/network-interface restart, and restart network-manager. I've also tried turning the wireless switch at the front of the laptop off and on, many times.
Code:
$ lspci -nn
[...]
03:00.0 Network controller [0280]: Intel Corporation Wireless Wifi Link 5300 [8086:4236]
[...]
$ ifconfig wlan0
[Code]...
The info above is when I've taken my laptop out of suspend mode and it won't connect to the network. lsmod doesn't say anything about wifi nor wireless; iwlist does see my network, which my older Januty laptop is connected to without drama.

I recently went back to Linux on my netbook because Windows 7 was too laggy (1gb of RAM, go figure). I've never been able to connect to the protected wireless network on my campus without using Windows, though, so I was hoping someone could help me finally get that figured out.
The school has a how-to for connecting to the network using various operating systems, including Linux, here (scroll down to the bottom to choose OS). After following the guide through the CA certificate it mentions, the network manager tries to connect for a while then just sort of times out and asks me to enter the information again. Using Wicd, I noticed that this timeout appears to happen when trying to obtain an IP (after authentication).
My system: Acer Aspire One AOA150 with an Intel 4965AGN wireless card (installed by me a few months back, have had no problems with the card itself not working). I've installed Kubuntu 9.10 Netbook edition and done all available updates. My campus offers an unprotected "Visitor" network that I can connect to without issue, but they limit what you can access using the unprotected network so I need to be able to connect to the WPA2 one.
I've tried getting help from on-campus IT but keep getting told that none of them know how to use Linux, which makes me wonder who exactly wrote the how-to on their website... The guides on the website are for older versions of Ubuntu, but I figured they would remain applicable on a later-version Kubuntu install.

When I try to use Nautilus to connect to another computer on my network, and I attempt to connect using the name of the Windows XP computer I am connecting to, I get the following error; Could not display "smb://computername/". Error: Failed to retrieve share list from server Please select another viewer and try again. However when I attempt to connect using the IP address on the network, it connects instantly. smb://192.168.1.101/ Why doesn't it connect using the computer's name? What am I doing wrong?

So, I'm stumped. Ubuntu studio didn't come with nm-applet, so I installed it myself. Now that I have it, I can't connect to my network. Here's the output I get when I run it in the terminal:
Code:
** (nm-applet:1979): DEBUG: old state indicates that this was not a disconnect 0

The more I use Windows, the more disgusted I get with it lol. So I would really enjoy using Ubuntu on campus instead of Windows, but I can't seem to get it to work. They have PDF files explaining how to connect with Windows XP - Windows 7 and Mac OS X, but nothing for a Linux distro. Here is the link to the PDFs [URL], and here are the settings I've tried to use to connect [URL] . I know that the CA is right (unless I need to us the Ubuntu version).

have Karmic Coala runing on an IBM thinkpad X.41. Works great. My home network is all ethernet so I have a router , CAT5 cable to laptop.A coupleof times I've had power outages The laptop carries on as it's on battery power. When the power comes back , the router restarts, it reconnects after a few minutes but the laptop doesn't reconnect to the network seamlessly. On some other Linux distro's I've had running /etc/init.d/network restart will refresh everything. On Ubuntu I have /etc/init.d/networks but running restart In the end I needed to reboot the laptop to get the network back on.Perhaps this is a power management issue with the laptop ethernet card i.e losing power powers down the card and it never comes back up properly.

Recently I hibernated my computer, then when starting up again managed to boot into Windows instead. When I rebooted back into Ubuntu 10.04 my network card had stopped connecting to the internet.'s not a problem with my connection -- I'm posting this form Windows just fine. Using the network tools tool I can see that the card is inactive.I can use ifconfog to reactivate it, but it still won't connect.Attached is as many commands as I could find that provide information about the card

I have a beefy Win Box desktop that i'm using as a media server and i have a home network setup already using windows xp. I had everything running fine and the PC connects flawlessly to my Bravia TV and both my ps3's so i know the network and sharing settings are setup just fine. Anyways i got tired of all the Windows 7 BS and decided i would once again use Ubuntu on my Toshiba netbook. So the question is how in the heck do i get my Ubuntu netbook to connect to the Desktop? I've tried browsing the fourms but either i'm missing something of just a little slow. What "extensions" would i need to get and how would i go about implementing it from there?

I would share my long awaited success with connecting my ubuntu laptop up to my universities (University of Western Sydney) wireless network. The rumors appeared true and they have finally implemented 802.11x authentication instead of that horrible java app netdirect. I am sure you've been cursing at its erratic stability. There is no linux documentation for airUWS-Lite nor anything more imformative than there windows/mac point and click steps found at [URL]. However with a few simple clicks you can have stable working connection.
When connecting make sure you have theses settings.
Security: WPA & WPA2 Enterprise
Authentication: Protected EAP (PEAP)
#This is the settings that does not present itself correctly
Anonymous Identity: leave blank
PEAP Version: Automatic
Inner Authentication: MSCHAPv2
Username: <YOUR 8 DIGIT STUDENT NUMBER>
Password: your regular password

When I was on Windows I used to be able to connect my laptop to a printer that was plugged into the computer downstairs via the wireless network. This network is still in place, only now I am using ubuntu I haven't got a clue as to how I connect to this network,or if it is even possible at all! how I would go about printing over the network when the other computers on the network are all windows machines.

I setup a network bridge on pc A, with windows 7 installed on it, using windows default bridging tool. I connected computer B to computer A and Im trying to connect to the internet through the network bridge on computer A. Computer B (client) has two OS's installed, win XP and linux(tried with different distributions, didnt work). On windows XP everything is working, when i try to ping the router (after computer A) it also responds. On linux system nothing is working, and im not quite sure why.
I set up linux to receive IP adress from DHCP, which is router in this case (behind computer A), same way windows XP was configured. I decided to ask here, because I couldn't find anything on the net. My guess is windows-made bridge supports only windows-OS's but that would be kind of strange (its just a software bridge).

Having become so frustrated With the many bugs in 11.04 I have stepped backward and instead installed Ubuntu 10.10 onto my Dell laptop. Until now I have been very pleased, as nearly everything has worked well, straight out of the box. So, just as I thought I was home and dry I have noticed that I cannot see my Synology NAS drive on my network. This is doubly frustrating because my other PC, also running 10.10, has suddenly lost it's ability to see the NAS drive too. Throughout last week I used the NAS in conjunction with my Ubuntu PC without a hitch but now it's gone. The NAS is visible to both Windows and Macs it's just the Ubuntu machines that cannot use it. It is also vaguely annoying knowing that the NAS itself uses a Linux OS or maybe that could be a clue to what's wrong.
As things stand my Apple Macs can see each other, they see the Windows box, see the NAS and see the shared folders on the Ubuntu machines. The Windows machines see the Macs, each other, the NAS and the Linux shared folders. The Ubuntu machines only see the Apple Mac shares, no Windows and no other Ubuntu shared folder nor the NAS.
It is curious because the little program Avahi Zero Conf Browser can see absolutely everything on my network yet the Ubuntu GUI is proving to be the most difficult thing to network using anything other than than a web browser. Is there a concise definitive reason why Linux (Ubuntu) is so infernally difficult to network? I am not very experienced with Linux or the terminal but was hoping that this system might by now have become a little more user friendly for ordinary people.
Could there also have been something in a recent OS update that has killed off my PC running Ubuntu's ability to see the NAS where previously there has been no problem.

I have a fairly new install of 10.04 on a Dell laptop (about a week). Everything was running well, connecting wirelessly to the interneet through my home router (WPA/WPA2). Today, for some reason, I lost my connection to the internet. The network manager tells me I'm connected to my router, but all the lines on the wifi indicator are gray and there is no internet access. I reinstalled the 2 sets of packets for my BCN4312 (bcmwl-kernel-source and b43-fwcutter ), but no change.

I'm trying to connect to a data server (basically a big hard drive) in my lab with my computer. On the Mac that's at the workbench next to me, you enter Go -> Connect to Server. From there, enter the IP address that I have (I can't find a server name--just the IP.). It asks you which subsystem you want, queries you for a user name & password, and then opens a window with all the files. Meanwhile, on my Ubuntu machine, I have a "Connect to Server" option under "Places" on my main menu. But when I choose that, I need to select what kind of server it is, from several options that don't seem right. (It's not FTP, it's not SSH, it's not a form of HTTP, and that leaves "Windows share?") I've tried several things, but usually get back 'Cannot display location "smb://<IP-ADDRESS>/" The specified location is not mounted'. I've tried many ways of mounting this drive, but it usually gives me permission denied errors (even though I *know* I have the right login and password--I've logged in using the aforementioned Mac).

I recently downloaded and installed CentOS 5.3 DVD media.The media check passed. I proceed to install the operating system sucessfully. After installation, all my hardware is recognized, when compared to CentOS 5.2. Anyway, when I attempt to connect to my wireless network that uses either WEP/WPA/WPA2-- I get an error message that I cannot recall (it basically only came up when I entered the key) However, I can connect to my wireless network when it is unencrypted and no open/shared key is needed.I would like to be able to connect to my wireless network when
FYI: I am using a RealTek RTL8185 Wireless Driver.Also, I use CentOS as a workstation.

So I bought a used Dell Precision 390 Workstation and installed Ubuntu 9.04 on it. Everything seems to work fine, except for the built-in network card. Well, the graphics don't really work right, either, but I rather expected that, and I'll get to it later.
Anyway, when I boot Ubuntu and try to get on the internet, it says I'm not connected. When I open Network Tools, in the "Devices" tab, I get three Network device options: Loopback Interface, Ethernet Interface (eth0), and Unknown Interface (pan0). When I click on the ethernet device option, it shows me the hardware address of the interface, that it has multicast enabled, and that it is "Active", but I get no IP address.
Is there something really stupid that I'm missing? Do I need to do something special the first time I hook up an ethernet cable? I don't seem to remember having to do that on other Ubuntu boxes.

I installed Ubuntu on an old desktop last night and am having some problems with my wireless connection.I've searched around a bit and tried a few solutions but nothing seems to be working so hopefully someone can help. I'm using a Netgear WG111v3 wireless USB adapter and am attempting to connect to a Sky Broadband modem, the connection shows up in the list of avaliable networks after clicking on the network symbol and after attempting to connect for a while it then asks for the WPA password.
I enter the password and then this repeats over and over again continuously asking for the password and me continuously entering it. I know the password is correct as I'm using it on my laptop and other home computer right now.I've tried connecting to a hidden wireless network and inserting the network name and password as some have suggested and I've also tried adding the details from my router into the connection; so that I have manually entered the information rather than automatically finding it, this also hasn't worked.I should probably add that earlier today I seemingly randomly got connected and then managed to run some updates but since then it has disconnected and the same problem is repeating over and over. Sorry if thats quite a long explanation but I thought I'd try and make it as clear as possible,

set the number of retries networkmanager attempts to connect to a network to infinity?
I live in an area of Australia were wired internet dare not tread (or so say the ISPs). My only real choice is 3G wireless broadband, and even that is iffy at times. Often late at night the network towers do "something" (reset, maintenance, etc. - no idea) and the internet drops out, networkmanager tries to reconnect, fails, tries again, (etc. etc.) until it ultimately gives up, requiring human intervention when the towers are done with whatever it is they are doing. This happens frequently, and I'd like to have networkmanager keep trying "forever" until it connects so I don't have to restart the connection each morning.
Where would such a thing be set? How does networkmanager know when to give up?

I just installed Ubuntu server edition on to an old Dell desktop. The only problem is that I can't get the Internet to work. I have tried the following and I guess it doesn't work:
Code:
sudo ifconfig eth0 192.168.1.52/24 up
sudo route add default gw 192.168.1.1
Each of those commands don't give me any error and it would seem like everything works fine, until I try to ping google or any website and I get an error that tells me that no host was found. I am using version 10.04 of Ubuntu server.
