| + | ====== VPN using VPNC ====== | ||
| + | The company I'm working for is using a Cisco VPN concentrator for ingoing VPN connections to the company.\\ | ||
| + | Using VPNC it's possible to connect from your Linux Fedora client.\\ | ||
| + | With fedora 14 VPNC is supplied as a NetworkManager plugin in package NetworkManager-vpnc. I have although not been able to get a working VPN connection using the VPNC NetworkManager plugin.\\ | ||
| + | But VPNC is working from the command line...... | ||
| + | |||
| + | Installed packages:\\ | ||
| + | vpnc-0.5.3-7.fc13.x86_64\\ | ||
| + | vpnc-script-0.5.3-7.fc13.noarch\\ | ||
| + | NetworkManager-vpnc-0.8.1-1.fc14.x86_64 | ||
| + | |||
| + | The configuration file for VPNC is located in /etc/vpnc/default.conf: | ||
| + | #IPSec gateway my.vpn.gateway | ||
| + | #IPSec ID my.ipsec.id | ||
| + | #IPSec secret mysecret | ||
| + | # your username goes here: | ||
| + | #Xauth username | ||
| + | |||
| + | The default parameters should be modified to reflect your site configuration. You can get the parameters from your system administrator | ||
| + | |||
| + | If you have a .pcf configuration file from a Windows installation of the Cisco VPN client, it is easiest to convert this file.\\ | ||
| + | |||
| + | The tool used for converting is called pcf2vpnc. For some unknown reason the pcf2vpnc file (perl script) provided with fedora does not have execution rights.\\ | ||
| + | Fix permissions for /usr/share/doc/vpnc-0.5.3/pcf2vpnc: | ||
| + | chmod 750 /usr/share/doc/vpnc-0.5.3/pcf2vpnc | ||
| + | |||
| + | Convert your .pcf file: | ||
| + | /usr/share/doc/vpnc-0.5.3/pcf2vpnc <path&filename_to_.pcf_file> <outputfile> | ||
| + | |||
| + | Copy the <ouputfile> file to /etc/vpnc/default.conf | ||
| + | |||
| + | If you just want to convert the enc_GroupPwd the cisco-decrypt tool can be used: | ||
| + | cisco-decrypt <enc_GroupPwd> | ||
| + | | ||
| + | With a proper /etc/vpnc/default.conf in place start vpnc: | ||
| + | vpnc --local-port 0 | ||
| + | |||
| + | Provide your password and your are connected to the network.\\ | ||
| + | If you hit ifconfig a <tun> device should apear: | ||
| + | |||
| + | tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 | ||
| + | inet addr:<ip> P-t-P:<ip> Mask:255.255.255.255 | ||
| + | UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1412 Metric:1 | ||
| + | RX packets:0 errors:0 dropped:0 overruns:0 frame:0 | ||
| + | TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 | ||
| + | collisions:0 txqueuelen:500 | ||
| + | RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) | ||
| + | |||
| + | Where <ip> is your IP on the VPN network. | ||
| + | |||
| + | To disconnect use: | ||
| + | vpnc-disconnect | ||
