NAME /usr/etc/appletalk/atconfig - enable AppleTalk on an interface SYNOPSIS atconfig intr [-net n] [-optnet n] [-optstart sn -optend en] [-node d] [-start sn -end en] [-f] [-D] atconfig -clear atconfig -attach intr DESCRIPTION The atconfig command enables AppleTalk on an interface. It is similar in function to ifconfig(1m). When atconfig is run, the interface uses the Apple Address Resolution Protocol (AARP) to determine its net and node number. When run on the loopback lo0, atconfig sets the net and node of a local pseudo-network. Specifying a intr of "default" will configure the first interface in the ifaddr list. All numeric arguments may be specified in hexadecimal by prepending them with a 0x. The flags are defined as follows: -net n Specifies that atconfig will use net number n. If a net number is specified, and it conflicts with net information gathered from RTMP packets, EINVAL will be returned. A net number must be specified when configuring the loopback interface (lo0). -optnet n Specifies that atconfig will use net number n, net range n-n. This differs from -net in that if there is another router using a different net number, no error message will be returned. If -optstart and -optend are used, they specify a network range to be used only if it does not conflict with an existing router. These modes are useful for configuring K-Talk on a network where other AppleTalk routers exist, but are not reliable. -node d This specifies that AARP will begin trying to acquire a node number at node d. If the node number is not specified, it defaults to 128 (0x80). It does not specify the actual node number obtained, only where to start. -start sn -end en This specifies the start and end of the network range. These arguments are only used when you want to set up an extended network range (more than one node number). If the start and end are not specified, atconfig defaults to the range already in use on the network (if there are other routers), or to provisional mode there are no other routers. In provisional mode, network range 65280-65534 (the provisional range) is used. This will allow K-Talk to communicate with other AppleTalk devices on an Ethertalk network with no routers. -f specifies that atconfig will use the specified net number for the local pseudo-net even if it already appears in routing tables. This option is used to maintain single numbers for the pseudo-net when there are routers that do not properly process delete-route packets. -D causes debugging information to be printed first when the flag is encountered in the command line, and again when the arguments have been processed. It is mostly used to check argument parsing. -clear is used to reset all AppleTalk kernel information. It should be done only when all AppleTalk services have been halted (with an atinit halt). It will clear all interface configuration information, as well as the AARP and routing tables. After clearing the interface, you should wait for 10 seconds to allow the routing tables to be rebuilt before running any additional atconfig commands. The main use of the -clear option is to clear a configuration when you plan to switch your network configuration. -attach is used on Streams implementations (currently, only Solaris) to make an interface ``known'' by the AppleTalk Protocol, but does not configure it. This is used to allow routing packets through on an interface in order to determine the prefered net range. On these systems, an interface will not show up in the atinfo(1) list until it has either been attached or configured. DIAGNOSTICS atconfig: old-style arguments. New command would be: ... The arguments passed to atconfig were in the format of old versions of atconfig A new-style command line will be printed to ease conversion. atconfig: permission denied You must be root to configure interfaces. atconfig: socket: ... atconfig could not open an AppleTalk socket. This usually means that AppleTalk is not installed in the kernel. atconfig: invalid interface xx The specified interface is not valid. Use atinfo(1) to get a list of the interfaces. atconfig: interface xx already configured The interface is already configured. You must clear it with atconfig -clear before you can configure it again. atconfig: no net number specified on net with no other routers This means that you did not specify a net number on a network that does not have any other AppleTalk routers. You need to specify a network number with a -net flag. To do this, edit /usr/etc/appletalk/services and change the atconfig line for the interface. atconfig: illegal parameters start=x net=y end=z. startnet <= net <= endnet One of the parameters startnet, endnet, or net is invalid. Usually means that you set a net number that was not within the existing network range. To fix this, edit /usr/etc/appletalk/services and remove the conflicting -net argument from the atconfig line for the interface. atconfig: SIOSETADDR failed (xx): ... The ioctl to set the address failed. Usually this means that the parameters specified conflict with configurations already existing on the network. atconfig: K-Talk kernel modules not loaded If you are running a system with loadable kernel modules, the loading of the kernel modules failed. Check for error messages from atalkmodload. If you are not running a system with loadable kernel modules, then you are running a non-AppleTalking kernel. Use mkkernel to build an AppleTalking kernel, copy it to /, and reboot. CAVEATS The first interface to be successfully configured becomes your default interface. This is the interface where AppleTalk services are registered. FILES /usr/etc/appletalk/services The file where atconfig commands are placed. SEE ALSO atinfo(1)
