Faka i-Cacti (i-Network Monitoring) kwi-RHEL/CentOS 8/7 kunye ne-Fedora 30
Isixhobo se-Cacti sisixhobo esivuleleke kumthombo ovulekileyo wokubeka iliso kuthungelwano olusekwe kwiwebhu kunye nesisombululo segraphing senkqubo yeshishini le-IT. I-Cacti yenza ukuba umsebenzisi enze iinkonzo zokuvota ngamaxesha aqhelekileyo ukwenza iigrafu kwiziphumo zedatha usebenzisa i-RRDtool. Ngokubanzi, isetyenziselwa ukwenza igrafu yothotho lwedatha yeemethrikhi ezinjengesithuba sediski, njl.
Kule ndlela yokwenza, siza kukubonisa indlela yokufaka kunye nokuseta isicelo esipheleleyo sokujonga inethiwekhi ebizwa ngokuba yiCacti usebenzisa isixhobo se-Net-SNMP kwi-RHEL, i-Cent

Isihluzi somnatha njengoko sisazi sonke ukuba ludonga lomlilo kwiLinux. Firewalld yidaemon eguquguqukayo yokulawula iifirewall ngenkxaso yeendawo zothungelwano. Kwinguqulo yangaphambili, i-RHEL kunye ne-CentOS sisebenzisa iiptables njengedaemon yesakhelo sokucoca ipakethe.
Kwiinguqulelo ezintsha ze-RHEL-based based distributions ezifana ne-Fedora, i-Rocky Linux, i-CentOS Stream, i-AlmaLinux, kunye ne-openSUSE - i-interface ye-iptables iyatshintshwa yi-firewalld.

Mafutshane: Esi sikhokelo siphonononga indlela yokuvala i-IPv6 kwi-RHEL, i-Rocky Linux, kunye nonikezelo lwe-AlmaLinux.
Kwi-computing, kukho iindidi ezimbini zedilesi ye-IP; IPv4 kunye ne-IPv6.
IPv4 yidilesi ye-32-bit equlathe ii-octets ezi-4 ezahlulwe ngamaxesha amathathu. Sesona sikimu sedilesi ye-IP esisetyenziswa kakhulu kwaye sixhasa ukuya kuthi ga kwiidilesi ze-IP ezingama-232. Kukho ithuba elihle lokuba isixhobo sakho sisebenzisa idilesi ye-IPv4 ukuqhagamshela kuyo nayiphi na inethiwekhi – enentambo okanye engenazingcingo.
Kwelinye icala, IPv6 yidilesi ye-1
