NAME
atmarp - administer classical IP over ATM connections SYNOPSIS
atmarp -a atmarp -c [[atm]number] atmarp -q ip_addr [qos qos] [sndbuf bytes] atmarp -s ip_addr [itf.]vpi.vci [qos qos] [sndbuf bytes] [temp] [pub] [null] atmarp -s ip_addr atm_addr [qos qos] [sndbuf bytes] [temp] [pub] [arpsrv] atmarp -d ip_addr [arpsrv] atmarp -V DESCRIPTION
atmarp is used to maintain the ATMARP table of the ATMARP demon. The table can be listed, new PVC and SVC entries can be added, and exist- ing entries can be deleted. In addition to that, atmarp is also used to create new IP over ATM interfaces. Note that the kernel has its own ATMARP table containing only entries for destinations to which a connection exists. The table of atmarpd can also contain currently unused entries. OPTIONS
-a list the current ATMARP table. -c create the specified IP interface. If the interface number is omitted, the operating system assigns the next free number and atmarp prints the resulting interface name (e.g. `atm0') on standard output. -q sets the QOS and the send buffer size to use as the default for all VCs generated for that IP network (ip_addr must be the address of the network). -s set up a PVC or create an SVC entry. The following options are recognized: qos qos uses the specified quality of service (see qos(7) for the syntax). UBR at link speed is used by default. sndbuf bytes tries to set the send buffer to the specified number of bytes. A system default value is used if sndbuf is not specified. temp does not mark the entry as permanent, i.e. it will time out and then be removed. pub publishes the entry (only relevant for ATMARP server). ATMARP requests for entries not marked for publishing yield an ATMARP_NAK response. null uses NULL encapsulation instead of LLC/SNAP encapsulation on the PVC. This option is not available for SVCs, because the LLC/SNAP header is required to identify ATMARP packets. null also implies that the entry is permanent. arpsrv identifies the entry pointing to the ATMARP server. Note that the node acting as the ATMARP server must have no ATMARP server entry in its ATMARP table. -d delete the specified ARP entry. In order to prevent accidental deletion of the ATMARP server entry, the arpsrv flag must be speci- fied when deleting it. -V print the version number of atmarp on standard output and exit. FILES

NAME
atmarpd - ATMARP demon SYNOPSIS
atmarpd [-b] [-d] [-D directory] [-l logfile] [-m] [-n] atmarpd -V DESCRIPTION
atmarpd implements the ATMARP protocol as specified in RFC1577 and RFC1755. Address resolution requests are sent from the kernel (using a comparably simple protocol) to the ATMARP demon, which then performs the dialog with the network. atmarpd can operate as an ATMARP client and as an ATMARP server. If also supports the concurrent use of several IP over ATM interfaces. atmarpd is configured from the command line using the atmarp program. Unless debugging is enabled, the ATMARP table is written after every change to the file /var/run/atmarpd.table (or to a file with the same name in a different directory, if the -D option is used). Note that atmarpd disables support for SVCs if signaling is not available at start time, i.e. if atmsigd is not running. OPTIONS
-b Run in background (i.e. in a forked child process) after initializing. -d Enables (lots of) debugging output. By default, atmarpd is comparably quiet. -D dump_dir Changes the directory where atmarpd writes its table (atmarpd.table). By default, /var/run is used. -l logfile Write diagnostic messages to the specified file instead of to standard error. The special name syslog is used to send diagnostics to the system logger. -m Enables merging of incoming calls if the address is known. An incoming connection on which no InARP reply has been received yet, but which originates from an ATM address for which an ATMARP entry already exists, is automatically added to that entry. This assumes that there is a 1:1 mapping between IP addresses and ATMARP addresses. By default, this assumption is not made, which fre- quently results in the setup of duplicate connections. Note that RFC1577 requires that an ATMARP server sends an InARP request on an incoming connection. Merging may therefore violate RFC1577 in this case. -n Prints addresses in numeric format only, i.e. no address to name translation is attempted. -V Prints the version number of atmarpd on standard output and exits.

atmarpd removes ATMARP entries from the kernel table while refreshing them. AUTHOR
