NAME

       nsd-xfer - AXFR client to transfer zones from a name server

SYNOPSIS

       nsd-xfer [-4] [-6] [-a address[@port]] [-p port] [-s serial] [-T tsiginfo] [-v] -z zone -f file servers

DESCRIPTION

       Nsd-xfer is program to transfer zones from a name server using AXFR.  NSD is a complete implementation of an authoritative DNS nameserver.

OPTIONS

       -4     Only send to IPv4 addresses.

       -6     Only send to IPv6 addresses.

       -a address[@port]
              Specify the source address (and port) to send from.

       -f file

              Specify the port to send to.

       -s serial
              Specify the serial of the current zone. The zone is only transferred if the master server has a zone with a greater serial number.

       -T tsiginfo
              Use  TSIG  to verify the zone transfer. The tsiginfo file must contain the TSIG key information. The file is removed upon successful
              reading of the key. The format of the tsiginfo file is described in the doc/README file (section 3.3).

       -v     Be more verbose.

       -z zone
              Specify the zone to receive.
