NAME
dgserver - Provide IPIP tunnel routes to AmprNet clients.
SYNOPSIS
dgserver [-c conffile] [-i device] [-p port] [-t exptimer] [-d]
DESCRIPTION
- dgserver accepts specially formatted UDP datagram from Am
- prNet 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 re
- quired.
- Sending the dgserver program a SIGHUP will cause it to
- flush its knowledge of the available routes and re-read its con
- figuration file.
OPTIONS
- -c conffile
- specifies a configuration file to read if the de
- fault is not desired.
- -i device
- specifies the name of the tunnel device to config
- ure 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 mes
- sages 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 automat
- ically detach from the terminal and run in the background.
