Kev tso tawm ruaj khov ntawm lub interface yog muaj los ua kom yooj yim teeb tsa lub network tsis muaj - NetworkManager 1.40.0. Plugins rau kev txhawb nqa VPN (Libreswan, OpenConnect, Openswan, SSTP, thiab lwm yam) yog tsim los ua ib feem ntawm lawv tus kheej txoj kev loj hlob.
Kev tsim kho tseem ceeb ntawm NetworkManager 1.40:
- Nmcli hais kom ua kab interface siv tus chij "--offline", uas tso cai rau kev sib txuas cov ntaub ntawv hauv cov ntaub ntawv tseem ceeb yam tsis tau nkag mus rau keeb kwm yav dhau NetworkManager txheej txheem. Tshwj xeeb, thaum tsim, nthuav tawm, tshem tawm thiab hloov chaw cuam tshuam nrog lub network interface, cov lus txib "nmcli txuas" tam sim no tuaj yeem ua haujlwm yam tsis tau nkag mus rau keeb kwm yav dhau NetworkManager txheej txheem ntawm D-Bus. Piv txwv li, thaum ua tiav cov lus txib "nmcli -offline kev twb kev txuas ntxiv ...", nmcli kev siv hluav taws xob yuav tsis xa daim ntawv thov mus rau cov txheej txheem keeb kwm yav dhau los ntxiv kev sib txuas profile, tab sis yuav ncaj qha tawm mus rau stdout qhov cuam tshuam ntawm kev teeb tsa hauv keyfile hom, uas tso cai rau koj siv nmcli hauv scripts los tsim thiab hloov kev sib txuas profiles . Txhawm rau qhib, tus tsim profile tuaj yeem khaws cia hauv /etc/NetworkManager/system-connections directory. # Kho cov ntaub ntawv txuag nrog "600" txoj cai (muaj rau tus tswv nkaus xwb). umask 077 # Tsim ib qhov profile hauv keyfile format. nmcli --offline kev twb kev txuas ntxiv hom ethernet con-name my-profile \ | tee /etc/NetworkManager/system-connections/my-profile.nmconnection # Hloov cov profile nmcli —offline kev twb kev txuas hloov kho connection.mptcp-flags enabled, teeb liab \ < /etc/NetworkManager/system-connections/my-profile.nmconnection \ | tee /etc/NetworkManager/system-connections/my-profile.nmconnection~ mv /etc/NetworkManager/system-connections/my-profile.nmconnection~ \ /etc/NetworkManager/system-connections/my-profile.nmconnection # Tom qab rov sau dua profile ntawm lub disk, reload lub chaw NetworkManager nmcli kev twb kev txuas reload
- Ntxiv kev txhawb nqa rau MPTCP (Multipath TCP), qhov txuas ntxiv ntawm TCP raws tu qauv rau kev teeb tsa kev ua haujlwm ntawm TCP kev sib txuas nrog kev xa cov pob ntawv ib txhij ntawm ntau txoj hauv kev los ntawm kev sib txawv network cuam tshuam nrog cov chaw sib txawv IP. NetworkManager tam sim no tuaj yeem tswj hwm qhov chaw nyob IP uas tau tshaj tawm lossis siv hauv MPTCP ntxiv, suav nrog kev teeb tsa cov chaw nyob ntawd, zoo ib yam li cov txheej txheem mptcpd ua li cas. NetworkManager kuj tseem txhawb nqa MPTCP hauv cov ntsiav los ntawm kev teeb tsa sysctl / proc/sys/net/mptcp/enabled thiab teeb tsa cov kev txwv uas tau teev tseg los ntawm "ip mptcp txwv" hais kom ua. Txhawm rau tswj MPTCP kev ua tiav, cov cuab yeej tshiab "connection.mptcp-flags" tau thov, los ntawm qhov koj tuaj yeem pab MPTCP thiab xaiv qhov chaw nyob tsis pub dhau (lub teeb liab, subflow, thaub qab, fullmesh). Los ntawm lub neej ntawd, MPTCP tau cia li qhib hauv NetworkManager yog sysctl / proc/sys/net/mptcp/enabled yog teem rau hauv lub ntsiav.
- Kev sau cov kev txwv kev sib txuas lus tau muab Cov chaw nyob IP rau DHCP (DHCP daim ntawv xauj tsev) rau cov ntaub ntawv /run/NetworkManager/devices/$IFINDEX (cov ntaub ntawv khaws cia rau hauv [dhcp4] thiab [dhcp6] seem), uas tso cai rau koj txiav txim siab txog kev khi los ntawm kev nyeem cov ntaub ntawv yam tsis tas nkag mus rau D-Bus lossis khiav cov lus txib "nmcli -f txhua lub cuab yeej qhia eth0".
- ipv4.link-local parameter tau ntxiv rau qhov kev sib txuas profile rau khi hauv zos IPv4 txuas rau intranet chaw nyob 169.254.0.0/16 (IPv4LL, Link-local). Yav dhau los, IPv4LL chaw nyob tuaj yeem raug teev los ntawm tus kheej (ipv4.method=link-local) lossis tau txais los ntawm DHCP.
- Ntxiv parameter "ipv6.mtu" los teeb tsa MTU (Maximum Transmission Unit) rau IPv6.
- Tshem tawm cov cai los ntawm qhov tsis siv DHCPv4 tus neeg siv khoom siv raws li cov cai los ntawm systemd. Kev siv n-dhcp4 los ntawm pob nettools tau siv ntev los ua tus neeg siv khoom DHCP.
- Ua kom DHCP rov pib dua thaum MAC chaw nyob ntawm lub cuab yeej hloov pauv.
