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
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
