- Nkwado agbakwunyere maka MPTCP (Multipath TCP), ndọtị nke usoro TCP maka ịhazi ọrụ nke njikọ TCP na nnyefe nke ngwugwu n'otu oge n'ọtụtụ ụzọ site na ntanetị netwọk dị iche iche jikọtara ya na adreesị IP dị iche iche. NetworkManager nwere ike jikwaa adreesị IP ndị a kpọsara ma ọ bụ jiri na ntinye MPTCP ọzọ, gụnyere ịhazi adreesị ndị a na-akpaghị aka, dị ka usoro mptcpd si eme ya. NetworkManager na-akwadokwa ime ka MPTCP dị na kernel site na ịtọ sysctl /proc/sys/net/mptcp/enabled na ịtọ oke nke iwu "ip mptcp limits". Iji chịkwaa nhazi MPTCP, a na-atụpụta ihe onwunwe ọhụrụ "connection.mptcp-flags", site na nke ị nwere ike ime ka MPTCP wee họrọ akara ọrụ adreesị (signal, subflow, backup, fullmesh). Site na ndabara, MPTCP na-akpaghị aka na NetworkManager ma ọ bụrụ na sysctl /proc/sys/net/mptcp/enabled atọrọ na kernel.
- Ọ ga-ekwe omume dee paramita njikọ njikọ IP maka DHCP (DHCP lease) na faịlụ / run/NetworkManager / ngwaọrụ / $ IFINDEX (a na-echekwa ozi na ngalaba [dhcp4] na [dhcp6]), nke na-enye gị ohere ikpebi njikọ site na naanị. ịgụ faịlụ na-enweghị ịnweta D -Bus ma ọ bụ mee iwu "nmcli -f all device show eth0".
- Agbakwunyela paramita ipv4.link-local na profaịlụ njikọ maka ijikọ njikọ IPv4 mpaghara na adreesị intranet 169.254.0.0/16 (IPv4LL, Njikọ-local). Na mbụ, adreesị IPv4LL nwere ike iji aka kọwaa ya (ipv4.method=link-local) ma ọ bụ nweta site na DHCP.
- Oke agbakwunyere "ipv6.mtu" iji hazie MTU (Igbo Nnyefe Kachasị) maka IPv6.
- Koodu ewepụrụ na mmejuputa onye ahịa DHCPv4 ejighi ya dabere na koodu sitere na sistemu. Ihe mmejuputa n-dhcp4 sitere na ngwugwu nettools ejirila ogologo oge dịka onye ahịa DHCP.
