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
