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

Uninzi lwamanani oThungelwano oluQhelekileyo lwePort yeLinux

Kwi-computing, kunye nokunye, iinethiwekhi ze-TCP/IP kunye ne-UDP, i-port yidilesi enengqiqo edla ngokunikezelwa kwinkonzo ethile okanye ukusebenzisa isicelo kwikhompyutheni. Isiphelo soqhagamshelwano esihambisa i-traffic kwinkonzo ethile kwinkqubo yokusebenza. Iizibuko zisekwe kwisoftware kwaye zihlala zinxulunyaniswa nedilesi ye-IP yomamkeli.

Indima ephambili yezibuko kukuqinisekisa ukuhanjiswa kwedatha phakathi kwekhompyuter kunye nesicelo. Iinkonzo ezithile ziqhutywa kumazibuko athile ngokungagqibekanga, umzekelo, uthutho lwewebhu limamela kwizibuko 80 (443 yetrafikhi efihliweyo),

Uyifaka njani kwaye uyisebenzise iNethiwekhi yeTor kwiWebhu yebhrawuza

Ubumfihlo be-Intanethi buba yinto enkulu kwaye abasebenzisi be-Intanethi abachaphazelekayo bahlala bekhangela iindlela ezisebenzayo okanye izixhobo zokusefa iwebhu ngokungaziwa ngesizathu esinye okanye esinye.

Ngokusefa ngokungaziwa, akukho unokutsho ngokulula ukuba ungubani, apho uqhagamshela khona okanye zeziphi iisayithi ozindwendwelayo. Ngale ndlela, unokwabelana ngolwazi olubuthathaka kwinethiwekhi yoluntu ngaphandle kokubeka esichengeni ubumfihlo bakho.

Inethiwekhi yeTor liqela leeseva ezisebenza ngokuvolontiya ezivumela abantu ukuba baphucule ubumfihlo babo kunye nokhusel

UWoof-Ukutshintsha ngokulula iiFayile ngaphezulu kweNethiwekhi yasekhaya kwiLinux

I-Woof (ifutshane kwiWebhu iFayile enye yeSibonelelo) sisicelo esilula sokwabelana ngeefayile phakathi kweenginginya kuthungelwano oluncinci lwasekhaya. Iqulathe iseva yeHTTP encinci enokusebenzela ifayile ekhankanyiweyo inani elinikiweyo lamaxesha (okungagqibekanga kube kanye) kwaye emva koko iyayiphelisa.

Ukusebenzisa i-woof, yibongoze nje kwifayile enye, kwaye umamkeli unokufikelela kwifayile ekwabelwana ngayo nge-browser yewebhu okanye usebenzisa umgca womyalelo womxhasi wewebhu onjenge-kurly (i-curl enye indlela) ukusuka kwi-terminal.

Enye inzuzo yewoof ngaphezu kwezinye iz

I-WonderShaper-Isixhobo sokunciphisa i-Network Bandwidth kwi-Linux

I-Wondershaper siskripthi esincinci se-bash esenza ukuba unciphise umda womnatha we-bandwidth kwiLinux. Isebenzisa inkqubo yelayini yomyalelo we-tc njengomva wokuqwalasela ulawulo lwendlela. Sisixhobo esiluncedo sokulawula i-bandwidth kwi-Linux server.

Ikuvumela ukuba usete ireyithi yokukhuphela ephezulu kunye/okanye isantya esiphezulu sokulayisha. Ukongeza, ikwakuvumela ukuba ucime imida oyibekileyo kwaye unokubonisa imeko yangoku yojongano olusuka kumgca womyalelo. Endaweni yokusebenzisa iinketho ze-CLI, unokuqhubeka ngokuqhubekayo njengenkonzo phantsi kwe-systemd.
