KVM mit PXE / DHCP / TFTP

Created: 04 March 2016 | Written by vincent | Print | Email | Hits: 5404

KVM mit PXE / DHCP / TFTP

TFTP (tftpd-hpa)

apt install tftpd-hpa

ich musste unter

vi /etc/inetd.conf

den tftp auskomentieren # weil sonst der Port UDP/69 blockiert war

DHCP

DHCP Server Konfig

vi  /etc/dhcp/dhcpd.conf

cat /var/lib/dhcp/dhcpd.leases

service isc-dhcp-server restart
service isc-dhcp-server start
service isc-dhcp-server stop

shows the used IP

grep "^lease" /var/lib/dhcp/dhcpd.leases |sort |uniq |wc -l
or

egrep "lease|hostname|hardware|\}" /var/lib/dhcp/dhcpd.leases
or

dhcp-lease-list /var/lib/dhcp/dhcpd.leases

PXE
