= bootpd, tftpd: Internet booting == SYNOPSIS *ip/bootpd* [ *-dsq* ] [ **-f**__ dbfile__ ] [ **-x**__ network__ ] *ip/tftpd* [*-dr*] [ **-p**__ port__ ] [ **-h**__ homedir__ ] [ **-x**__network__ ]  _Bootpd_ listens for Internet BOOTP requests and broadcasts a suitablereply to each request that matches an entry in the network database_dbfile_ (default: */lib/ndb/local*). The BOOTP protocol is typicallyused by a remote system as it boots, to obtain its Internet address andother configuration data such as the addresses of servers (see forinstance the *bootp* file in _ip_(3)). _Dbfile_ is in _ndb_(6) format, as interpreted by _attrdb_(2). _Bootpd_uses the following attributes: *auth*::  authentication server name or address*bootf*::  name of the client's boot file*dom*::  fully-qualified domain name*ether*::  hardware (MAC) address; only Ethernet is supported*fs*::  file server name or address*ip*::  client's Internet address*ipgw*::  gateway from client's subnet (IP address)*ipmask*::  subnet mask*ipnet*::  network name*sys*::  system name (client identifier) _Bootpd_ replies to an incoming request only if its hardware addressmatches the value of the *ether* attribute of an entry in _dbfile ._ Iffound, the reply contains all the other requested data that is containedin the entry; if an item is missing, it is sought in the entries forsuccessively higher networks (described by *ipnet* entries) that containthe requesting system's address. The `vendor specific' part of the replyconveys the file server and authentication server addresses to Infernoclients. Before answering a request, _bootpd_ rereads _dbfile_ if it haschanged since last read. The *-s* option causes _bootpd_ to sniff the network for BOOTP trafficand print it, but not reply. The *-d* option prints debugginginformation; giving it twice prints even more. The *-x* option tells_bootpd_ to use a _network_ other than */net*. Currently _bootpd_ printsa message to standard output each time it replies; the *-q* option keepsit quiet. _Tftpd_ is mainly used to send kernels and configuration files tomachines booting from the network. It listens for incoming TFTP filetransfer requests on the given UDP _port_ (default: 69) and responds bysending or receiving a file as requested. _Homedir_ is the currentdirectory for transfers, */services/tftpd* by default, and requests thatuse a relative path name refer to files in or below that directory. Ifthe *-r* option is given, absolute path names are also restricted to_homedir_. _Tftpd_ runs as *none* (the least privileged user) and cansend only files with general read permission, or write files that aregenerally writable. Normally _tftpd_ uses the network directory */net*,but another can be specified with the *-x* option. The *-d* optionprints a debugging trace on standard output. == FILES */lib/ndb/local*::  network configuration file*/services/tftpd*::  default directory for relative pathnames == SOURCE */appl/cmd/ip/bootpd.b* +*/appl/cmd/ip/tftpd.b* == SEE ALSO _attrdb_(2), _ip_(3), _ndb_(6), _cs_(8), _dns_(8)
