Hi Gurus, I have a question:
I have a connection VPN to my Branch Office, but some day the Network administrator send an e-mail and he tell me that I must be disconnected the VPN. But In that moment I don't use the VPN, Someone was coneccted to the VPN I think.
The Question is: I want to know if exist a System or tecnology that when you access a VPN, the firewall (or equipment that manage the VPN) register the MAC address of the Station/PC that use the VPN? For example If someone know my user/pass of my VPN can do anything in my branch Office, and the Network Administrator would think that I do it. When I'm not the person that use the VPN.
Thantk gurus for your suggestions or advice

NETWORKMANAGER(8) System Manager's Manual NETWORKMANAGER(8)NAME
NetworkManager - network management daemon
SYNOPSIS
NetworkManager [--no-daemon]
DESCRIPTION
The NetworkManager daemon attempts to make networking configuration and operation as painless and automatic as possible by managing the
primary network connection and other network interfaces, like Ethernet, WiFi, and Mobile Broadband devices. NetworkManager will connect
any network device when a connection for that device becomes available, unless that behavior is disabled. Information about networking is
exported via a D-Bus interface to any interested application, providing a rich API with which to inspect and control network settings and
operation.
NetworkManager will execute scripts in the /etc/NetworkManager/dispatcher.d
directory in alphabetical order in response to network events. Each script should be (a) a regular file, (b) owned by root, (c) not
writable by group or other, (d) not set-uid, (e) and executable by the owner. Each script receives two arguments, the first being
the interface name of the device just activated, and second an action.
up The interface has been activated. The environment contains more information about the interface; CONNECTION_UUID contains the UUID
of the connection. Other variables are IP4_ADDRESS_N where N is a number from 0 to (# IPv4 addresses - 1), in the format
"address/prefix gateway". IP4_NUM_ADDRESSES contains the number addresses the script may expect. IP4_NAMESERVERS contains a space-
separated list of the DNS servers, and IP4_DOMAINS contains a space-separated list of the search domains. Routes use the format
IP4_ROUTE_N where N is a number from 0 to (# IPv4 routes - 1), in the format "address/prefix next-hop metric", and IP4_NUM_ROUTES
contains the number of routes to expect. If the connection used DHCP for address configuration, the received DHCP configuration is
passed in the environment using standard DHCP option names, prefixed with "DHCP4_", like "DHCP4_HOST_NAME=foobar".
down The interface has been deactivated.
vpn-up A VPN connection has been activated. The environment contains the connection UUID in the variable CONNECTION_UUID.
vpn-down
A VPN connection has been deactivated.
hostname
The system hostname has been updated. Use gethostname(2) to retrieve it.
OPTIONS
The following options are supported:
--no-daemon
Do not daemonize. This is useful for debugging, and directs log output to the controlling terminal in addition to syslog.
DEBUGGING
The following environment variables are supported to help debugging. When used in conjunction with the "--no-daemon" option (thus echoing
PPP and DHCP helper output to stdout) these can quickly help pinpoint the source of connection issues.
NM_SERIAL_DEBUG
When set to anything, causes NetworkManager to log all serial communication to and from serial devices like mobile broadband 3G
modems.
NM_PPP_DEBUG
When set to anything, causes NetworkManager to turn on PPP debugging in pppd, which logs all PPP and PPTP frames and client/server
exchanges.
