Yadda zaka Sanya Hanyar IPv6 akan CentOS/RHEL 8

Adireshin IPv6 an haɓaka shi ne da tsammanin ƙarancin adiresoshin IPv4. Yana nufin warware gajiyar adiresoshin IPv4 ta hanyar amfani da hanyar sadarwa mai faɗi mafi fadi. Adireshin IPv6 adadi ne mai lamba 128 wanda ya ƙunshi ƙungiyoyi 8 da aka rarrabe dasu daga hanji kowane ɗayan lambobin hexadecimal 4.

Misali na adireshin IPv6 an nuna shi a ƙasa:

2001:1:1:1443:0:0:0:400

IPv6 yawanci ana kunna shi ta tsohuwa akan CentOS/RHEL 8. Don bincika idan an kunna IPv6 akan tsarinku, gudanar da umarnin:

$ sudo sysctl -a | grep ipv6.*disable

0imar 0 tana nuna cewa IPv6 yana aiki akan kuɗinka. Darajar 1 ya nuna cewa IPv6 an kashe. Sabili da haka, daga fitarwa da ke sama, IPv6 yana aiki.

Wata hanyar dubawa idan an kunna IPv6 shine ta hanyar duba hanyar sadarwar ku a/etc/network-scripts/directory. A halinmu, wannan zai zama/etc/sysconfig/hanyar sadarwa-rubutun/ifcfg-enps03 fayil.

Don haka bari mu aiwatar da umarnin da ke ƙasa sannan mu bincika idan an kunna IPv6.

$ cat /etc/sysconfig/network-scripts/ifcfg-enps03

Kasance cikin hangen nesa don zaɓin IPI6 na folIowing kamar yadda aka nuna:

  • IPV6INIT = eh - Wannan yana ƙaddamar da dubawa don magance IPv6.
  • IPV6_AUTOCONF = eh - Wannan yana ba da damar daidaitawar IPv6 ta atomatik don aikin.
  • IPV6_DEFROUTE = eh - Wannan yana nuna cewa an sanya tsoffin hanyar IPv6 zuwa aikin dubawa.
  • IPV6_FAILURE_FATAL = a'a - yana nuna cewa tsarin ba zai gaza ba koda kuwa IPv6 ya gaza.

Abubuwan da aka samo a sama yana tabbatar da cewa IPv6 address yana aiki. A kan tashar, zaka iya bincika adireshin IPv6 na maɓallan ka ta hanyar tafiyar da umarnin IP ɗin da ke ƙasa.

$ ip a
OR
$ ip -6 addr

Kasance a kan hangen nesa don inet6 kamar yadda aka nuna a ƙasa.

Don dakatar da IPv6 na ɗan lokaci, gudanar da umarnin:

$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
$ ip -6 addr

Don kunna IPv6, gudanar da umarnin:

$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0

Sannan sake kunna NetworkManager don canje-canje don amfani.

$ sudo systemctl restart NetworkManager

Don dakatar da IPv6 har abada, shirya GRUB/sauransu/tsoho/grub fayil. A cikin layin, GRUB_CMDLINE_LINUX , sanya ra'ayoyin ipv6.disable = 1 a ƙarshen layin kamar yadda aka nuna.

Don amfani da canje-canje, sake yi tsarin ku.

Kamar dai IPv4, daidaitaccen aikin IPv6 mai yiwuwa ne ta amfani da kayan aikin nmcli. Koyaya, wannan ba'a ba da shawarar ba saboda daidaitaccen aikin IPv6 yana fuskantar kurakurai kuma yana da wahala.

Bugu da ƙari, aiki ne wanda yake lura da wane adireshi IPv6 aka sanya shi ga waɗanne tsarin. Hatsari shine da alama kuna iya rikita tsarinku.
