Can you recommend any guides/how-tos as https://docs.freebsd.org/en/books/handbook/advanced-networking/#network-dis= kless and man 8 diskless seem to only address freebsd clients and servers? I'm looking for an example with say ubuntu as client. or briefly describe how= =20 you did it? The clients need to always get the same IP address. I guess this would be tied to the MAC in some way. One issue is that there is already a dhcp server active on the router. If the freebsd tftp/pxe/nfs server is another dhcp server on the same network, they'll clash. How can this be avoided? thanks, --=20 J. --pG3BIwHX3XejJ6n4 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAmDHarcACgkQs8o7QhFz NAVxPw/+MUs0iuiC8Q8mYFVKKhC2vD5MBIljnBf1xGLvXHmdaSm6cxUUyt0OmMqF HFTPbfNkwFz0dvuCmGGQPodXII/OkaTtbbZ9J8rpnF48Gt/nn9JjNgNxtVyJVCnr ciEn2QbmDnSmlzr5+G0jZPRCNBrqZuvleWuPgmUfEIWL/sjUFZ0OCPr2OskQsOGw bDnssHWAuB+jPlzYkL51TLvrnp1VF3F6F+WkYEoFd78OzSYYZSMbGSsBltZ7IEUo cyBk94NdgLeKPyviid17VU1IMW2LIlVpkuPQIfRZldhRLwLZCzhqGe2WrD8YVLcC 9wVwaDbVTHk+JmduDDvwSWCpa2WMBesyXL9ZLsX83DlndgwhxFK3j7ZmxnfQkHMo dT7COCKSaoBO82GuDA3tKOw2KlT+C0l2qamRGfEpSvP9SmmB8r9zoKJu9xkqSYXZ 0eYmPKtOMqXLOBImSHLHKBfvecuezckrbBf/0de1zQE7leYoR2Np6jt1Dfcv3TCg g2qyUXfUJTv6EkUENsj1N4lJrA4Klfp4DwMmNs4rWXohue/ZP/LQ14mOp5ycS5v4 ka/mL8Z6LdLsZ+4cDnpVcXF0gBaJMggUrxD0qMK1T6TTp0SJzkG7ypFIgqb5ITvI nnnR8g5d/FfpcD3/iNnFpjKw4fFYhsAg4BdhQTgKeeii7NsolCc= =JJI5 -----END PGP SIGNATURE----- --pG3BIwHX3XejJ6n4--
