Ubuntu Networking :: Network Manager Vpnc Connects But Receives Nothing?
Oct 25, 2010
I'm trying to connect to a Cisco VPN at work from Ubuntu 10.10. On earlier versions, I was able to import the config and get it working. In 10.10, though, the best I've gotten is being able to connect to the VPN, see the welcome message, and have packets sent over the tunnel. I don't receive any packets, though.
The command-line vpnc client connects just fine. I found this bug report: [URL]
The symptoms it describes are exactly what I'm seeing. The apparent solution is to "make sure in your config that LZO Compression is enabled (checked) under Advanced"; however I see neither an option for compression nor an "Advanced" tab, button, or anything on my VPN config in Network Manager.
I've been trying to connect to my office Cisco VPN several time using the network-manager-vpnc GUI in Ubuntu Karmic with no success. I read a couple of articles and i tried using the direct command line way:
Code: sudo vpnc office with the following /etc/vpnc/office.conf file:This is fictional data Code: IPSec gateway vpn.office.com IPSec ID office IPSec secret 0ff1c3 which worked perfecly.
So i went back to the Network Manager GUI way and i used the same credentials. Same fictional data I got a libnotify message telling me it couldn't connect.Anyone know how i could troubleshoot this issue? Would be great to have it integrated in gnome instead of running a background command which is not tracked by nwm.
With fc12 vpnc starts allows me to connect to my work site then everything works fine til I try and start a remote desktop connections to a windows client use tsclient. All I get is a blackscreen and my laptop is hung.
At work without the vpnc it works fine if I start the vpnc from nm it performs the exact same way and I get the blackscreen.
I have disable selinux.I also disabled the firewall
there was another gentlemen on here with the same issue.
The only way out is a hard reboot and there are no messages in the logs that say there were any problems.
I got a little problem with network manager. I got two connections in it, with two different DNS-Servers, because the one of my provider is very slow I surf with opendns, but sometimes that slows down too, so I want to change if necessary. Both connections got the same fixed IP.That worked all fine, until I got my new router (it's a Netgear WGU 624). It's connected by cable and I configured it like the old one. But for some reason instead of connecting to the manually configured connections, my fedora 10 creates a new one "auto eth 0" with a dynamic IP. So every time I boot or switch on from standby my PC connects with this one and I have to manually set it to the right connection. There's no chance to edit or delete it cause those two buttons are grey and won't work. I also tried restarting network manager manually and I also tried starting it with su as root.
I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,
cups cupsys ssh pi memtester nfs-common aptitude safe-upgrade
At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.
This is used for a headless(no monitor, no keyboard) system running some custom applications.
Here are two problems.
1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?
2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:
Code:
However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.
/etc/cups/printers.conf has been wiped out to look like this:
Code:
My 'good' printer configuration is copied to printers.conf.O
To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.
So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.
I just got vpnc setup to work with my VPN at work and now I am trying to figure out how to limit the traffic that is routed through the VPN while I'm connected to it. I only want traffic going to the local domain to be routed through the VPN.This is what my vpnc config file looks like:
Code: IPSec gateway publicdomain.example.com IPSec ID XXXX
I've got a Zotac MAG HD-ND01 with XBMC live installed. This is built on Karmic Koala and runs very nicely through the wired NIC.
I configure the box using a cable. I'm using WPA2-PSK and it is clearly authenticating OK.. It gets an IP address.. the AP shows a connection to the box. My XP laptop connects to the access point OK.. just can't connect to the box via the wireless, and it can't see the network using wireless.
I have followed a number of threads on connecting Atheros 9XXX wireless [URL] but no joy.
Also, can Ubuntu connect to the AP at any speed greater than 54MB? My windows PC connects at 144MB+ . Will ndiswrappers connect at those sorts of speeds?
lspci -nn 04:00.0 Network controller [0280]: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01) iwconfig lo no wireless extensions.
I recently installed Xubuntu 10.04 on my desktop computer that had a USB wireless adapter DLink DWA-140. I didn't have to install any additional drivers to get it to work. I put in the network SSID and the password and was connected immediately. However, when I try starting firefox it doesn't load any sites. Can anyone help me in approaching this problem. I have a DLink DIR-655 router. If I should gather more information to get this problem solved then please let me know and I will do so. Edit: Now I am unable to connect to the network. When I click the network icon in the taskbar, my home network is not visible while it is visible under another ubuntu computer I'm running.
I installed Ubuntu 10.04 32-bit on an old desktop (1.5ghz Pentium 4, 20GB hard drive, 768MB RAM) a week or two ago, at the same time that I installed Xubuntu 10.04 on an even lower performance IBM tower server. The server functions perfectly and my other (Windows XP) desktop recognized it from the start, as did the Ubuntu desktop. However, I rearranged a few ethernet cables the other day without turning off the desktops and ever since my Ubuntu machine does not recognize my server, even though all of the devices are connected via ethernet cable to a linksys router and it connects to the internet without a problem. I'm a linux newbie - this is my first move away from Windows - and I don't know where to turn. Far more confusing is the fact that, when I boot from a LiveCD, the network is recognized and I can read/manipulate files on my server without a problem. Oh, and I briefly flirted with OpenSUSE KDE (not as noob-friendly as Ubuntu, so I'm back) and encountered the same problem.
Needless to say, booting from the hard drive is preferable to booting from CD every time
I have one pc on which I have installed slackware and samba (fixed IP, mask 255.255.255.0) I have another PC (also XP) which also has fixed IP running XP, and I can connect that to the slackware server easily My third PC connects to the internet and gets its IP address from the Cisco router(?) that provides the IP and mask on boot up.
I tried changing the IP and Mask on the slackware server to match the internet PC (which uses a mask 255.255.254.0) but the PC mask and IP changed on the internet PC I want the PC that connects to the internet to also be able to connect to the slackware server, but I see no need for the slackware server to also connect to the internet - I will mainly use it as a file server When I worked for another company I think the IT department talked about having 2 network cards in the PC that connects to the internet
I know Windows forward and backward but I am so new to linux it's just wrong. I just installed fedora (like 1hr ago) on and old toshiba laptop with a WiFi PC card. Everything seems to work fine except. My Networks connects to my home Wifi network but it will not connect to internet. When it connects the IP address isn't even close to being in the same range as my other laptops and PCs. Like I said I'm new to linux but I'm wanting to learn. Any fixes for this issue? Which linus book is the best one to read for a beginner? Other then not connecting to internet I have no complaints.
It hangs at the end and I can see in /var/log/messages "modem-manager: (net/tun0) could not get port's parent device" and then eventually "withdrawing workstation service for tun0".
My settings are correct and other people seem to be able to connect.
I am not using KNetworkManager because of an issue on my machine regarding rfkill.
I used to plug in my camera into the USB interface and was able to open the picture storage with the KDE file manager - the file manager came up automatically.
Now since I have installed openSUSE 11.2, digikam insists to take over.
How can I configure SUSE 11.2 that it offers me the file manager option again? It would be great (but not necessary) if it offered a selection "Open with ..." when the USB cable is plugged in.
I am using a fully up to date openSUSE 11.3 and today, I decided to upgrade my KDE 4.4.4 to Factory. The update went without a hitch, everything continued to work, including all of the items in my workspace.So now I am running KDE 4.4.95 and it looks nice. I like the new System Settings where the advanced tab is gone and everything is presented in a single window.
The only snag I have hit so far, is that Knetworkmanager no longer displays the network that I am connected to when I right click its icon in the tray. The screenshot may make clear what I am talking about.I am currently connected via a wireless network, which nm-tool confirms. However, it is not shown in the Knetworkmanager menu.
I WAS using opensuse 11.1 with gnome networkmanager and vpnc. I am NOW using opensuse 11.2 with gnome networkmanager and vpnc.When vpn concentrators are configured, they are configured with 'split horizons' (or not). If not, a default route is required from the client to pass ALL client traffic through the vpn connection. (when the connection is established, the vpn client replaces the default route on the client machine to point to the host site) If 'split horizons' is enabled, only the traffic bound for the host site is passed through the vpn connection.
What I have noticed, is since I installed 11.2, the vpn client is NOT enabling split horizon on connections that call for it. In stead, it is putting in a default gateway every time. This is a big problem, because for those sites that are configured for split horizon, doing this means that no Internet traffic will pass unless you manually adjust the route table.
I recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:
I am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?
I have used ubuntu in the past but had a lot of hardware issues with it and unfortunately moved back to windows (( BUT i have tried Ubuntu again and all seems to work great except wifi My wifi connection is sort of working because when i run SUDO IWLIST SCAN it does pull up all available networks. But in the network manager icon on the panel i left click but i see no networks and can't connect to anything. I WOULD LOVE TO keep Ubuntu and use it permanently but I must get wifi working or else this won't be possible.
I have the problem with my notebook, that, after I used it at work, the network-manager always tries to autoconnect after boot. He has no cable network and so I get the message "not connected" after a while.how to tell the network-manager, not to autoconnect each time?
I recently put Linux on a Thinkpad T40 I got. The wireless card works out of the box--I can see nearby networks. However, I can't connect to mine. network-manager would try (spin spin spin), fail, ask for the password, and then go back to the beginning and repeat indefinitely. This happened to me on a different computer, and on that one all I had to do was use wicd instead of network-manager. So I installed wicd, but it's not working either--it hangs at "Obtaining IP address".
I've found many, many threads with people who had the same problem, but none of their fixed worked for me.
I also tried to get wifi going manually, using this guide, but that didn't work.
My wifi connection drops sometimes and, for some reason, Network Manager attempts to connect to my neighbor's network, which requires a password (which I don't know). Is there any way to blacklist a wireless network so that the Network Manager will never attempt to connect to it?
I just upgraded Ubuntu 10.04 LTS. Now when I use vpnc to connect from the command line using vpnc-connect, I'm not only prompted for my password as usual, but now also being prompted for a "Passcode". Here's what the login attempt looks like:
Enter password for jegan@some.vpnhost.net: Passcode for VPN jegan@216.23.18.33:
I've been using the same /etc/vpnc/default.conf file for years.Note that I do not have an /etc/vpnc.conf, or any of the other configuration files that vpnc checks for.Here's a modified copy of my /etc/vpnc/default.conf file:
## generated by pcf2vpnc IPSec ID CRL-Qfe IPSec secret XM-j-245Rv[code].............
I use VPNC to connect to a Cisco VPN. I am able to connect, but some issues exist when I use SSH. For example, I login through SSH to a computer in the VPN and I execute ls => it works. If I execute ls -la => connection stalls. I think it stalls every time it is supposed to return more content (top, ls /etc).
If I do scp from my end to server => works. If I do scp from server to my end => connection stalls.
I'm trying to setup a VPN using VPNC. All is well and I can create the VPN.
The problem is that CNTLM does not want to connect in the VPN Further more I am not sure what to look for? The logs are empty and CNTLM only reports 502 Parent proxy unreacheable.
How can I trace what the problem is?
My setup: Ubuntu 10.10 64 CNTLM 0.91~rc6-0ubuntu1.1 VPNC 0.5.3r449-2
I installed network-manager-vpnc, configured cisco vpn through NetworkManager. It works slow, but the bigger problem is that after minute or so the connection just freezes.Then I tried kvpnc. It works like it should from speed point of view. But it also hangs up after minute or two.Tried to change MTU of my wired connection to 1500 - no good.Tried to uncomment line in /etc/ppp/options "mru 542" - no good.
Created /var/run/vpnc because it was giving some error "can't open pidfile /var/run/vpnc/pid for writing".From logs everything seems fine except for "nm-dispatcher.action:Script '/etc/NetworkManager/dispatcher.d/01ifupdown' exited with error status 1." in last line. If I use kvpnc it gives no errors.SO, how do I debug this thing or does anyone knows something I don't in this case?
When I connect to my company's VPN (it's a Cisco), it connects just fine and displays the broadcast message, but once connected I can't ping anything or ssh anywhere. Not on the private network, not on the Internet [URL], nothing. I can still browse the web without difficulties when connected to the VPN, but no ssh or ping. With ping, it properly resolves the host name, but I get 100% packet loss.
Once I disconnect from the VPN, a ping of [URL] works exactly as expected.
I don't have any firewalls set up on this host that I'm aware of (unless something is installed and configured by default).
I had trouble connecting to a wireless network with openSUSE, so I tried the YAST network manager to see if that fixed it. Not only did it not fix it, but now I cannot connect to any network, wired or wireless. I tried to open the default network manager and it said "Network management disabled". How do I re-enable it?I also have set YAST settings back to their originals with no luck.
I have a little home server with Ubuntu 10.10, actually it is already backing up my web hosting daily via a cron.daily script.. But I would like to do the same with my Windows laptop, which would it be the best way to do so?
since the Ubuntu pc is (almost) always turned on it would be no profit to have it mount the Win PC at startup, indeed I could have a cron.hourly script to check if the Laptop is connected to the network and to back it up once a day, thus by checking a small text file with written the date of the last backup BTW how do I check if the Win PC is connected to the network? How do I mount it via samba? Do you suggest to backup stuff simply moving files, via tar (as I already do with my web host) or with rsync?
