IPXSAPD(8)

NAME
ipxsapd - IPX service advertising daemon

SYNOPSIS
ipxsapd [ [-d] logfilename]

DESCRIPTION
Ipxsapd uses IPX Service Advetising Protocol (SAP) to gather and propagate information about network services (e.g. file servers) and its adresses over IPX internetwork. In conjuction with ipxripd(8) and IPX kernel support ipxsapd allows Linux to act as IPX internetwork router. Before ipxsapd is started ipxripd(8) should be running.

OPTIONS
-d
    Turn on debug output. It means that all incoming or outgoing SAP packets are dumped to the log file.
logfilename
    Specifies the name of the log file where changes made to service database and optional debug output are logged. If the name of the log file is missing, no log file is generated.

SIGNALS
The following signals are handled by ipxsapd. SIGINT
    Dumps current service database to the log file.
SIGTERM,SIGHUP
    Shutdowns SAP agent (sends service is down broadcasts) and exits.

VERSION
This man page is correct for version 0.9 of ipxsapd. The implementation of SAP is conforming to the IPX Router Specification v1.10 (available via ftp ftp.novell.com).

BUGS
Ipxsapd reads IPX interface configuration information only at startup. Therefore ipxsapd must be stopped before any IPX interface configuration change is done and restarted after it.
 In responding to broadcast requests (IPX destination node is 0xFFFFFFFFFFFF) split-horizon algorithm is not followed, because there is no way to distinguish between direct and broadcast request.
 Simplified algorithm based only on 'hops to server' information is used for selecting nearest server. Reachability of a server is not tested when adding the new one to the service database. This two problems are implied by inaccessibility of IPX routing database and will be removed by merging ipxripd(8) and ipxsapd into a single program.
 All the violations of the IPX Router specification mentioned above should result in small increase of the network traffic or a client attaching to a distant server on looped network, but they cannot cause inoperability of Linux IPX router.
