Cisco VPN client in Linux
Connecting to a network using Cisco VPN is quite easy. I’ve got it with Fedora 7, but I suppose the steps are the same regardless the distribution you are using.
The latest iteration (v2.3.4) of the Cisco Secure Firewall Migration Tool adds public beta support for S2S VPN migrations from ASA: Policy-based (crypto map) Pre-Shared key authentication type VPN configuration to Firepower Management Center VP. If you don't need the 'official' Cisco AnyConnect VPN software, I highly recommend installing the 'network-manager-openconnect-gnome' package in the Ubuntu Repository. It uses OpenConnect which is an open source client for AnyConnect. Cisco VPN Client for Linux. Here is the steps to install the Cisco VPN client application on linux based servers. We have found several customers use their cisco router to manage their VPN Network, therefore by following this simple steps you should be able to install and configure your linux server as a VPN client.
The first step is to install a Cisco compatible VPN client. Cisco has a client, but there’s a free alternative called vpnc. To install it in Fedora, just run the following sentence as root:
# yum install vpnc
Once you have it installed, you can start using it:
# /usr/sbin/vpnc
Enter IPSec gateway address:
Enter IPSec ID for 192.168.2.1
Enter IPSec secret for [email protected]:
Enter username for 192.168.2.1:
Enter password for [email protected]:
but if you are going to connect often, you’d better put all that stuff in a config file. Edit as root, with your favourite text editor, the /etc/vpnc/default.conf file:
![Cisco Cisco](/uploads/1/1/9/5/119550656/641968814.jpg)
![Cisco Cisco](/uploads/1/1/9/5/119550656/732797167.png)
# vi /etc/vpnc/default.conf
Then type your connection data:
IPSec gateway
IPSec ID
IPSec secret
Xauth username
If you don’t have a ‘secret’, then it’s probably your password. At least, it has worked for me.
I suppose you have realized that your password it’s not stored in the file. That’s the only data you will need to type when you try to connect.
After setting up this, you will be able to connect using
# /usr/sbin/vpnc
Type your password when prompt. In that step, you may get an error if your network administrator is using simple DES encryption:
# /usr/sbin/vpnc
Enter password for [email protected]:
/usr/sbin/vpnc: peer selected (single) DES as 'encrytion' method.
This algorithm is considered too weak today
If your vpn concentrator admin still insists on using DES
use the '--enable-1des' option.

In that case, you will need to connect using the following command:
# /usr/sbin/vpnc --enable-1des

To disconnect, just run the following:
# /usr/sbin/vpnc-disconnect
