35 Set the level of debugging messages written to the log file. The
36 value should be between 0 and 5, with 0 being no debugging, and 5
40 This will be where all logging and debugging information is written
41 to. This may be either a filename, such as

51 If set, the process id will be written to the specified file. The
52 value must be an absolute path.

66 .BR primary_dns , " secondary_dns"
67 Whenever a PPP connection is established, DNS servers will be sent to the
68 user, both a primary and a secondary. If either is set to 0.0.0.0, then that
71 .BR primary_radius , " secondary_radius"
72 Sets the RADIUS servers used for both authentication and accounting.
73 If the primary server does not respond, then the secondary RADIUS
76 .BR primary_radius_port , " secondary_radius_port"
77 Sets the authentication ports for the primary and secondary RADIUS
78 servers. The accounting port is one more than the authentication
79 port. If no ports are given, authentication defaults to 1645, and
83 If set to true, then RADIUS accounting packets will be sent. A
85 record will be sent when the session is successfully authenticated,
88 record when the session is closed.

94 accounting records (in seconds). Note: checking of this interval

100 Secret to be used in RADIUS packets.
103 A comma separated list of supported RADIUS authentication methods
104 ("pap" or "chap"), in order of preference (default "pap").
106 .B allow_duplicate_users
107 Allow multiple logins with the same username. If false (the default),
108 any prior session with the same username will be dropped when a new
109 session is established.
112 When the tun interface is created, it is assigned the address
113 specified here. If no address is given, 1.1.1.1 is used. Packets
114 containing user traffic should be routed via this address if given,
115 otherwise the primary address of the machine.
118 Address to send to clients as the default gateway.
121 Determines whether or not to send a gratuitous ARP for the
123 when the server is ready to handle traffic (default: true). This
124 setting is ignored if BGP is configured.
127 Sets the default speed (in kbits/s) which sessions will be limited to.
130 Number of token buckets to allocate for throttling. Each throttled
131 session requires two buckets (in and out).
134 If set to a directory, then every 5 minutes the current usage for
135 every connected use will be dumped to a file in this directory.
138 After starting up and binding the interface, change UID to this. This
139 doesn't work properly.
142 If set to true, then the current bandwidth utilization will be logged
143 every second. Even if this is disabled, you can see this information
149 Interval between regular cleanups (in seconds).
152 Number of packets to read off each of the UDP and TUN fds when
153 returned as readable by select (default: 10). Avoids incurring the
154 unnecessary system call overhead of select on busy servers.
157 Sets the scheduling policy for the

175 Maximum number of host unreachable ICMP packets to send per second.
178 Maximum number of packets of downstream traffic to be handled each
179 tenth of a second per session. If zero, no limit is applied (default:
180 0). Intended as a DoS prevention mechanism and not a general
181 throttling control (packets are dropped, not queued).
184 Multicast cluster address (default: 239.192.13.13).
187 Interface for cluster packets (default: eth0).
189 .B cluster_hb_interval
190 Interval in tenths of a second between cluster heartbeat/pings.
192 .B cluster_hb_timeout
193 Cluster heartbeat timeout in tenths of a second. A new master will be
194 elected when this interval has been passed without seeing a heartbeat
197 .B cluster_master_min_adv
198 Determines the minumum number of up to date slaves required before the
199 master will drop routes (default: 1).
202 Enable negotiation of IPv6. This forms the the first 64 bits of the
203 client allocated address. The remaining 64 come from the allocated
204 IPv4 address and 4 bytes of 0s.

217 define the attributes of BGP neighhbours. Valid commands are:
219 .BI "neighbour " peer " remote-as " as
221 .BI "neighbour " peer " timers " "keepalive hold"
225 specifies the BGP neighbour as either a hostname or IP address,
227 is the remote AS number and
230 are the timer values in seconds.
