Ubuntu :: Vpnc Disconnects After About 8 Hours

Feb 13, 2011

I've seen a problem staying connected to a Cisco VPN, this goes back a number of years.I was running 8.10 and it was fine.After I moved to 9.10, the problem started happening.My VPN connection to work would drop after 8 hours.I looked around for a while and ended up compiling the cisco provided client which works fine (but is a pain).I've been running 9.10 on my work laptop, and it experiences the same problem using vpnc, but I've been dealing with it because it's easier than using the Cisco client.

I installed 10.04 on my work desktop, my home desktop, and a personal laptop that was previously running 8.10, and all experience the same problem with vpnc.I even go so far as to keep one terminal open with a constant ping all day and it still drops after about 8 hours. A couple of others at work experience the same problem using vpnc. This is not a problem using the Cisco provided client, or running it on windows or os/x.Has anybody else seen this, or have any ideas on what I can start looking for to get this addressed?

Ubuntu Networking :: Internet Disconnects Every 3 Hours

May 2, 2011

I have a minor Internet issue. I have a static IP address with the modem acting as a gateway only to my ISP. My Ubuntu server hosts my public IP address and I use pppoeconf to connect. Every 3 hours I lose Internet. I have wrote a short script to reconnect. I doubt that it is my ISP trying to renew that often.

Ubuntu Networking :: Vpnc & Network-manager-vpnc Inconsistency?

Jan 13, 2010

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.

Feb 2, 2010

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.

The only way out is a hard reboot and there are no messages in the logs that say there were any problems.

Ubuntu :: No VPNC With Maverick Meercat?

Dec 25, 2010

I had a problem and had to reinstall ubuntu and figured I may as well upgrade to 10.10 since I had to do a fresh install. Well I assumed I would have to reinstall vpnc for my cisco vpn client but I can not figure out how to download it. When I do a search it seems the only vpn option is pptp. I really need it working as I am on call with my job.

Ubuntu Networking :: VPNC Prompting For Passcode?

Jun 12, 2010

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:

IPSec ID CRL-Qfe

Ubuntu Networking :: Use VPNC To Connect To A Cisco VPN?

Feb 28, 2011

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.

Ubuntu Networking :: Vpnc Freezes After Short Time?

Aug 11, 2010

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?

Ubuntu Networking :: Can't Ping Or Ssh When Connected To Cisco VPN Using Vpnc

Jan 21, 2011

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'm using Ubuntu 10.10, amd64 build.

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.

Fedora Networking :: Vpnc Doesn't Anymore On FC11?

Jun 23, 2009

Since I installed FC11 vpnc stop working. I get "vpnc: no response from target." I tried running it with "strace" and the reason is a timeout: poll([{fd=3, events=POLLIN}], 1, 4000) = 0 (Timeout)

I tried google and adding "NAT Traversal Mode cisco-udp" to the config file works for some people but not for me Does anyone had experience with vpnc 0.5.3 in FC11?

Fedora Networking :: NetworkManager-vpnc Doesn't Work

Jun 27, 2011

how nobody else could have run into this in the meantime. [URL] Two friends of mine are having the same issue on Ubuntu-11.4-machines. In short: Connecting to the Cisco-VPN via shell-command "vpnc" works flawlessly, whereas NetworkManager just doesn't connect at all. We had this working in older versions of Fedora/Ubuntu about some months ago...

Networking :: Vpnc Working Under Virtualbox Under Windows But Not On Host?

Aug 8, 2010

Our company uses a customized vpnc (based on and almost the same as vpnc 0.5.3). I first tested it on a Windows host under Virtualbox everything works straight away. But when I want to use it on a Linux host directly it always ends in "No response from target". I have tested this on Fedora 12 and the latest Ubuntu.
I thought of firewall settings but iptables -L on Ubuntu returns an empty list even.

OpenSUSE Network :: 11.2 Vpnc Does Not Handle Split Horizon Properly

Dec 30, 2009

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.

Networking :: Vpnc Freezes Computer With Kernel 2.6.33-gentoo-r2, X86_64

Jul 18, 2010

I am trouble trying to get vpnc to work on my laptop.

Using the same computer via Ubuntu, it works fine.

I used to use an older kernel with the cisco vpn client, but had to go through the motions of turning off cpus in order for it to work. I gave that trick a try and it does not work.

I pretty much followed the instructions from: Gentoo Linux Documentation -- Gentoo vpnc HOWTO

The machine completely locks up right after I enter my password...

I don't see anything relevant in the /var/log/messages file.

Is there another log file to look into specific to the vpnc?

Fedora Networking :: Establishing A Vpn Connection Using Vpnc / Error Failed To Bind To 0.0.0.0:500: Address Already In Use?

Nov 24, 2010

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).

As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message

Quote:

Failed to bind to 0.0.0.0:500: Address already in use
[user@computer ...]# vpnc-helper --local--port 0

If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.

If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.

Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.

Does anybody have an idea how to enforce that the vpn connection is actually used?

Fedora Networking :: Kmanager-vpnc Vpn Key Lifetime Limit - GUI Doesn't Provide A Location To Enter Information

Jan 6, 2011

I am using KNetworkmanager-vpnc to VPN back to the office from home, the vpn connection works fine - for 15 minutes then I am disconnected. I am fairly certain that this is related to the Phase 1 key lifetime limit. The Knetworkmanager-vpnc GUI does not provide a location to enter this information. I think I found the config file that holds the connection information at /home/<user>/.kde/share/apps/networkmanagement/connections/ I just don't know the proper syntax to put in the file to specify a key life limit. Anyone out there know how to do this? I am using Fedora 14 x64 with knetworkmanager-vpnc 1.0.9-0.28.
