4.5. Networking
- When configuring a network interface manually, including static IP addresses and search domains, it is possible that a
search
entry will not be propagated to/etc/resolv.conf
. Consequently, short host names that do not include the domain name will fail to resolve. To workaround this issue, add asearch
entry manually to/etc/resolv.conf
. - To ensure that RFC3442-standard classless static routes provided by a DHCP server are processed correctly when using NetworkManager, the following lines should be placed into /etc/dhclient.conf or, if using per-interface DHCP options, /etc/dhclient-<ifname>.conf:
option rfc3442-classless-static-routes code 121 = array of unsigned integer 8; option ms-classless-static-routes code 249 = array of unsigned integer 8; also request rfc3442-classless-static-routes; also request ms-classless-static-routes;
These lines will ensure that RFC3442 classless static routes are requested from the DHCP server, and that they are properly processed by NetworkManager.
