NAME

ntx_arp − display and modify MVME339 ARP table

SYNOPSIS

ntx_arp [ −d device ] hostname
ntx_arp [ −d  device ] −a
ntx_arp [ −d  device ] −r hostname
ntx_arp [ −d  device ] −s hostname ethernet_address [ temp ] [ pub ]
ntx_arp [ −d  device ] −f filename

DESCRIPTION

Ntx_arp displays and modifies the Internet-to-Ethernet address translation table of the MVME339 host adapter.  The address translation table is used by the address resolution protocol (ARP). 
 
With no flags (excepting the −d option), ntx_arp displays the current ARP entry for hostname.  The host may be specified by name or by Internet dot notation. 

OPTIONS

−aDisplay all of the current ARP entries. 

−dSet the MVME339 raw device file name.  This option will override the default MVME339 device name of /dev/xedt/mvme338_c0. 

−fRead the file named filename and set multiple entries in the ARP tables.  Entries in the file should be of the form:

hostname ethernet_address [temp] [pub]

−rRemove (delete) an entry for the host called hostname. 

−sCreate an ARP entry for the host called hostname with the Ethernet address ethernet_address.  The Ethernet address is given as six hex bytes separated by colons.  The entry will be permanent unless the word temp is given in the command.  If the word pub is given, the entry will be published; for instance, the MVME339 host adapter will respond to ARP requests for hostname even though the host address is not its own. 

EXAMPLES

Display all ARP table entries for the second MVME339 host adapter:

 ntx_arp -d /dev/xedt/mvme338_c1 -a
 

FILES

/dev/xedt/mvme338_c0
