dgserver - Provide IPIP tunnel routes to AmprNet clients.

dgserver [-c conffile] [-i device] [-p port] [-t exptimer] [-d]

dgserver accepts specially formatted UDP datagram from AmprNet Dynamic Gateway clients. The datagram supplies the network address and mask of a network that the client wishes to have routed to it via IPIP encapsulation. An optional password may be supplied to the server to authenticate the client to it if required.

Sending the dgserver program a SIGHUP will cause it to flush its knowledge of the available routes and re-read its configuration file.

-c conffile

specifies a configuration file to read if the default is not desired.

-i device

specifies the name of the tunnel device to configure tunnel routes onto. The default value if this option is not supplied is "tunl0".

-p port

species an optional UDP port to use if the default of 1234 is not being used.

-t exptimer

specifies the time interval between refresh messages sent to the server. This should always be set to a value no larger than the dynamic route timer being used at the server. UDP is a lossy protocol so it may be wise to make this value at most half of the server route timeout to ensure that one lost datagram doesn't cause the route to be lost.

-d

causes the daemon stay running in the foreground of the terminal in which it was executed. The default is to automatically detach from the terminal and run in the background.

dgserver was written by Terry Dawson <terry@tao.linux.org.au> and based on the protocol described by the MFNOS implementation developed by Barry Siegfried, K2MF. Bug reports should be sent to <terry@tao.linux.org.au> or <terry@guglielmo.vk2ktj.ampr.org>.
