I-GNS3, i-real and virtual network simulator ye-Ubuntu

Esihlokweni esilandelayo sizobona uhlelo lokusebenza olubizwa nge- GNS3. Lokhu yi isoftware yomthombo ovulekile abanye abantu abavame ukukusebenzisa ukulingisa, ukuhlola, nokuxazulula inkinga a imvelo yenethiwekhi okubonakalayo futhi kwangempela. Lolu hlelo luzosivumela ukuthi sakhe futhi sisebenzise i-topology encane yenethiwekhi esingangeza kuyo amadivayisi enethiwekhi njengama-laptops, ama-desktops, amaseva, amaswishi, ama-routers, njll.

Ngaphambi kokuqhubeka faka i-GNS3 ku-Ubuntu 64bit, kungaba ukuhlakanipha ukubheka ngokushesha ukusetshenziswa kwayo nezici zayo. Okokuqala, yithi inguqulo ezinzile yakamuva yohlelo ingu-2.0.3. Kule nguqulo isicelo siletha izinguquko ezibalulekile zokwakha kanye nezici ezintsha maqondana nenguqulo yangaphambilini ezinzile.

Ekuqaleni komlando wayo, i-GNS3 yayiyi-desktop application kuphela kusuka kunguqulo yokuqala kuze kufike enguqulweni engu-0.8.3. Ngezinguqulo ze-1.x eza kamuva, lolu hlelo lokusebenza lwaqala ukunika abasebenzisi ikhono lokusebenzisa amaseva akude. Ku-version 2.0, uhlelo Izosinikeza ukuthi kungenzeka ukuthi amaklayenti amaningana angakwazi ukulawula i-GNS3 ngasikhathi sinye. Futhi konke "ukuhlakanipha kohlelo" kudluliselwe kuseva yalokhu, okwenza uhlelo lusebenze kangcono emsebenzini walo.

I-GNS3 hhayi kuphela iyahambisana namadivayisi weCisco. ICisco yilokho onjiniyela abaningi benethiwekhi abanentshisekelo yokwazi, kepha kukhona impilo ngale kwayo. Lesi yisona sizathu esikhulu sokuthi kungani abanye abahlinzeki bemithombo evulekile nabathengiswayo behambisana nalolu hlelo lokusebenza namuhla.

Izici ze-GNS3

Phakathi kokunye, lolu hlelo lokusebenza lunikeza umsebenzisi izici ezijwayelekile njengokuthi kungenzeka ukusebenzisa ukulingisa esikwenza njengobufakazi bomqondo noma ukuboniswa kwamakhasimende ngezinjongo zokuhweba. Akungabazeki ipulatifomu enhle yokufunda nokufundisa imvelo yenethiwekhi. Ngasikhathi sinye, ngokusetshenziswa kwelebhu ebonakalayo, ukusebenzisana kwabathengisi abaningi kungahlolwa kunethiwekhi.

Esinye isici esiphawuleka kakhulu ukuthi kuyindlela enhle ye- sekulingisa kwenethiwekhi yesikhathi sangempela ukuhlolwa kwangaphambi kokuthunyelwa. Ukuzama njalo kugcina kukusindisela izinkinga.

Lolu hlelo lokusebenza luzophinda lusinikeze amandla wokugijima ngokushesha futhi sihlole i-Hardware ehlukahlukene ngaphandle kwesidingo sehadiwe ephathekayo.

Ngokubhekisele kuzitifiketi zenethiwekhi, ungenza ngezifiso ama-topologies namalebhu ngaphakathi kwe-GNS3. Ngaphezu kwalokho, unga xhuma i-GNS3 endaweni yenethiwekhi yangempela.

Ungakwazi hlola zonke izici ye-GNS3 kuwebhusayithi yabo njengoba lonke uhlelo lokusebenza lubhaliwe. Ungahlola futhi ukuthi ungalulungisa kanjani lolu hlelo lokusebenza kunethiwekhi yakho yasendaweni.

Njengoba ngishilo, i-GNS3 isoftware yomthombo ovulekile ekhululekile ukulanda nokusebenzisa. Ungalanda izinhlobo ze IWindows, iMac OSX neLinux. Ikhodi yomthombo yesicelo iyatholakala ku- GitHub uma ufuna ukubheka ikhodi.

Faka i-GNS3 ku-Ubuntu

Ukufaka le software ohlelweni lwethu lwe-64-bit Ubuntu kulula kakhulu. Kulesi sihloko sizosebenzisa i-PPA abasinikeza yona kusuka iwebhusayithi yabo. Ukuqala kuzofanele sivule i-terminal (Ctrl + Alt + T) bese siqala ngokungeza okukhokhwayo sisebenzisa umyalo olandelayo:

sudo add-apt-repository ppa:gns3/ppa

Manje kufanele sibuyekeze kuphela uhlu lwezinhlelo kukhompyutha yethu bese sifaka uhlelo. Ukwenza lokhu, esigungwini esifanayo sibhala okulandelayo:

sudo apt-get update && sudo apt-get install gns3-gui

Khipha i-GNS3 kusuka ku-Ubuntu

Uma lolu hlelo lokusebenza lungakukhuthazi, lapha uzobona ukuthi ungalususa kanjani kalula. Njengenjwayelo, ukukhipha uhlelo kulula njengokulufaka.

Okokuqala, sizosusa uhlelo bese siqeda ngokususa okugciniwe ohlwini lwethu lwasendaweni. Sivula i-terminal (Ctrl + Alt + T) futhi kuyo sinamathisela i-oda lokuqeda uhlelo bese ngemuva kwalokho sihlanza noma yimaphi amafayela asalayo angahlala ohlelweni lwethu:

sudo apt remove gns3-gui && sudo apt autoremove

Manje, esigungwini esifanayo sizosusa okugcinwe ngokunamathisela umyalo olandelayo:

sudo add-apt-repository -r ppa:gns3/ppa
