GADMIN-OpenVPN-Server 0.0.7 (Default branch)

Image GADMIN-OpenVPN-Server is an easy to use GTK+ interface for the OpenVPN server in bridge mode. It allows generation of five signed certificates and keys, including HMAC-Firewall and user authentications. Bridge mode enables SAMBA browsing and printing across physically separated networks and or full-blown road warrior client capabilities. License: GNU General Public License v3 Changes:
This release adds iptables forwarding for tap+ interfaces. It uses ifconfig instead of ifup/ifdown scripts. It adds lowercase detection for firestarter user-pre contents. Image

NAME
eurephia-variables - eurephia configuration variables DESCRIPTION
Overview over all eurephia configuration variables. These variables are stored in the database and can be modified by the eurephiadm con- fig command. PASSWORD HASH
These variables are related to the password hash configuration. All of them must be set, but they can be changed over time without affect- ing the functionality of the already stored passwords. These parameters are the first to be set when eurephia_init is run. The minimum and maximum hash rounds are bechmarked for you with this tool to find more suitable numbers for the hardware eurephia will be running on. passwordhash_salt_length Sets number of bytes to use for the password hash salt. passwordhash_rounds_min Sets the minimum number of hashing rounds to perform when calculating new password hashes. passwordhash_rounds_max Sets the maximum number of hashing rounds to perform when calculating new password hashes ATTEMPTS SETTINGS
eurephia can blacklist user names, certificates and IP addresses based on number of failed attempts. The following parameters defines the limits of how many attempts you are willing to allow before blacklisting them. allow_cert_attempts Defines the number of attempts of failed login attempts you allow before you will blacklist the OpenVPN clients cerrtificate. This number should normally be higher than allow_username_attempts. Default is 5. allow_username_attempts Defines the number of failed ttempts for a user name can be tried before you will blacklist the user name from further attempts. Default is 3. allow_ipaddr_attempts Defines the number of failed attempts for an IP address to be used before you will blacklist the IP address from further attempts. This one should be the least strictest limit. You also need to consider if your clients will log in via a proxy or NATed network and how many of your clients will do so. If you experience many users failing to log on and more of them are behind the same proxy or NAT gateway, this may blacklist the IP address quicker than intended. But if among many failing attempts a valid authentication happens, the attempts counter will be reset again, so this limit do not need to be too forgiving. Default is 10. FIREWALL INTEGRATION
If you are running the OpenVPN server with eurephia on a Linux server, it is possible to let eurephia interact with the firewall as well. These settings will enable the firewall integration and tell eurephia how to interact with the firewall. These parameters are very ipta- bles oriented. The iptables firewall module must be enabled at compile time and be installed to work. firewall_interface This is the variable which enables firewall integration. This variable must point at the firewall driver, which is a shared object file which eurephia will load dynamically. These drivers are prefixed efw and will be found in the same lib or lib64 directory as the eurephia-auth and edb-sqlite modules. The variable must contain the full path to the driver module. firewall_command This defines the binary the firewall module will execute to help update the firewall. For iptables this defaults to /sbin/iptables. firewall_destination Defines which predefined firewall rule to use when updating the firewall. The default value is vpn_users. firewall_blacklist_destination This activates firewall based IP address blacklisting in addition to the internal blacklist in eurephia. This variable defines which firewall rule to use when wanting to blacklist an IP address. firewall_blacklist_send_to This is an optional parameter. Normally when eurephia blacklists an IP address it will default to drop the network packets from that client. You can use this variable to send it to a different firewall target. This is useful if you to, for example, log the incident to the system log before dropping the packets. EUREPHIA UTILITIES
These settings are used by the eurephia administration utility, eurephiadm. eurephiadmin_autologout This defines how long a eurephia administration utility may have an open session before it is considered inactive. When exceeding this limit, the administrator user will be out automatically. The unit for this setting is minutes and the default value is 10. eurephiadm_xslt_path The eurephiadm utility uses XSLT templates for generating the output to the screen. This variable gives you the possibility to have your own set of templates in a different directory instead of using the system wide XSLT templates installed by default. This vari- able is not set by default. SEE ALSO
