vpnc cannot connect to VPN due to vpnc-script

Getting problems on the Ubuntu 11.04 for openconnect... the failure after connecting says:

Got CONNECT response: HTTP/1.1 200 OK CSTP connected. DPD 30, Keepalive 20 Connected tun0 as 172.21.246.21, using SSL DTLS handshake failed: 2

I thought it is a kernel fault so I updated to 12.04 which didn't change the message. It could be that the vpnc-script has the problem.

Hi all, hoping somebody can help me out. My company has switched are cisco vpn from regular rsa login to certificate/rsa login. My vpnc worked fine before using rsa login. But now with certificate/rsa login, I can't seem to get it to work. I think I've read pretty much everything I can google about this issue but still not working. I'm using FC16 64bit.

I'm trying to run vpnc I get this error

vpnc-connect: can't open /dev/net/tun, check that it is either device char 10 200 or (with DevFS) a symlink to ../misc/net/tun (not misc/net/tun): No such device vpnc-connect: can't initialise tunnel interface: No such device

However when I check for the tun device I get

root@t............:~# ls -l /dev/net/tun crw------- 1 root root 10, 200 2012-11-02

As stated in a previous question I want to connect to 2 VPN servers at the same time and for each connection specify the IPs of computers I want to reach with it. One of this VPN connection is done with vpnc and a default.conf file, and the other one is done with a Cisco client (I am not able, for now at least to connect with vpnc because I don't have the IPSecrete element required to connect).

I need to know how to establish VPN connection with Cisco VPN using vpnc on Centos 5.6. I can start the connection but after a period of time the vpnc process doesn't exist in the process list when run

# pgrep vpnc

I don't know is that because the connection itself goes down or what?...if so, then how can I make the connection permanent?

The configuration file looks like this

Being disappointed by Gnome3 I am moving to KDE. Everything is fine, but VPN does not work (under Gnome ok.). Anyone has a similar experience?

Kernel: 3.3.5-2.fc16.x86_64

I'm currently attempting to establish a vpn connection, but I am unable to install a vpn client. I assumed installation would be as simple as sudo yum install vpnc, but CentOS is unable to find the vpnc package.

I browsed some more, and discovered I needed to install and enable the rpmforge repository for yum to find the package.

The Cisco VPN client, vpnc, enables your Linux workstation to connect to a Cisco 3000 series VPN concentrator PIX firewall. Until vpnc existed, corporate employees were often relegated to connecting to their company's network via a Windows machine or with Cisco's problematic VPN client for Linux. Thankfully, those days are over, but not without slight configuration effort.

On my XP laptop at work, I use the Cisco VPN Client v5.0.06. The settings that get me in are: Host: <IP for my target gateway> Group Authentication: name & password

But using Ubuntu 9.10 on my laptop, with vpnc and network-manager-vpnc installed, I haven't been able to vpn in.

In network-manager-vpnc, I set:
