7.1 ioctls Functional Grouping

These ioctls are related to NUI mapping. The NUI mapping table maps Network User Identifiers to particular facilities. The ioctls described in this section let you operate on NUI mappings. Note that any changes you make could disrupt other users. For this reason you require root access to use the ioctls that let you change the current settings.

Table 7-1 NUI mapping icotls


ioctl	description	access level
`N_nuidel`	delete specified NUI mapping	root only
`N_nuiget`	read specified NUI mapping	unrestricted
`N_nuimget`	read all NUI mappings	unrestricted
`N_nuiput`	store a set of NUI mappings	root only
`N_nuireset`	delete all NUI mappings	root only

These ioctls operate on a per multiplexor basis:

Table 7-2 Multiplexor ioctls


ioctl	description	access level
`N_getstats`	read X.25 multiplexor statistics	unrestricted
`N_zerostats`	reset X.25 multiplexor statistics to zero	root only

These ioctls operate on a per virtual circuit basis:

Table 7-3 Virtual circuit ioctls


ioctl	description	access level
`N_getoneVCstats`	get status and statistics for VC associated with current stream	unrestricted
`N_getpvcmap`	get default packet and window sizes	unrestricted
`N_getVCstats`	get per VC statistics	unrestricted
`N_getVCstatus`	get per VC state and statistics	unrestricted
`N_putpvcmap`	change per VC packet and window sizes	unrestricted

These ioctls start and stop packet level tracing:

Table 7-4 Packet level tracing ioctls


ioctl	description	access level
`N_traceon`	start packet level tracing	root only
`N_traceoff`	stop packet level tracing	root only

These ioctls manage the X.25 routing table. Using them may override values set using x25tool. The ioctls are:

Table 7-5 Routing ioctls


ioctl	description	access level
`N_X25_ADD_ROUTE`	add a new route or update an existing route.	root only
`N_X25_FLUSH_ROUTE`	clear all entries from table.	root only
`N_X25_GET_ROUTE`	obtain routing information for specified address	unrestricted
`N_GET_NEXT_ROUTE`	obtain routing information for the next route in the table	unrestricted
`N_RM_ROUTE`	remove the specified route	root only

These ioctls operate on a link:

Table 7-6 Link ioctls


Header	Header	Header
`N_getlinkstats`	retreive per link statistics	unrestricted
`N_linkconfig`	configure `wlcfg` database for a link	unrestricted
`N_linkent`	configure a newly linked driver	unrestricted
`N_linkr`ead	read the `wlcfg` database	unrestricted
