Mu mikorere no kubungabunga umuyoboro w'itumanaho, ni ikibazo gikunze kubaho ariko kigoye ko ibikoresho bidashobora gukoresha Ping nyuma yo guhuzwa mu buryo butaziguye. Ku batangira ndetse n'abahanga b'inararibonye, akenshi biba ngombwa gutangirira ku nzego zitandukanye no gusuzuma impamvu zishobora gutera. Iyi nkuru isobanura intambwe zo gukemura ibibazo kugira ngo igufashe kubona vuba impamvu nyamukuru y'ikibazo no kugikemura. Ubu buryo burakenewe kandi ni ingirakamaro haba mu miyoboro yo mu rugo no mu bigo. Tuzakwereka iki kibazo intambwe ku yindi, kuva ku igenzura ry'ibanze kugeza ku igenzura rigezweho.
1. Reba uko Connection Ihagaze kugira ngo urebe neza ko Signal ikora
Ishingiro ry'itumanaho rya interineti ni uguhuza ikoranabuhanga. Iyo igikoresho kinaniwe gukoresha Ping nyuma yo guhuza ikoranabuhanga mu buryo butaziguye, intambwe ya mbere ni ukureba niba urwego fatizo rukora. Dore intambwe:
Emeza ko umuyoboro wa interineti uhujwe:Genzura niba insinga y'umuyoboro ifunze neza kandi niba aho insinga y'umuyoboro iherereye hari umugozi. Niba ukoresha insinga itaziguye, menya neza ko insinga ikurikiza TIA/EIA-568-B standard (Common Direct Cable Standard). Niba ufite ibikoresho bishaje, ushobora gukenera kwambuka imipaka (TIA/EIA-568-A) kuko bimwe mu bikoresho bishaje bidashyigikira guhinduranya MDI/MDIX mu buryo bwikora.
Genzura Ubwiza bw'Umugozi w'Umuyoboro:Insinga y'umuyoboro idakora neza cyangwa ndende cyane ishobora gutuma ikimenyetso kigabanuka. Uburebure bw'insinga isanzwe y'umuyoboro bugomba kugenzurwa muri metero 100. Niba insinga ari ndende cyane cyangwa ifite ibyangiritse bigaragara (urugero: yacitse cyangwa yacitse), ni byiza kuyisimbuza insinga nziza hanyuma ukongera kuyisuzuma.
Reba Ibipimo by'Igikoresho:Ibikoresho byinshi bya interineti (nk'amadirishya, router, amakarita ya interineti) bifite ibimenyetso byerekana aho bihurira. Ubusanzwe, urumuri ruracana (icyatsi kibisi cyangwa umuhondo) nyuma yo guhuza, kandi hashobora kubaho urumuri rugaragaza ko amakuru yoherezwa. Iyo ikimenyetso kidacana, bishobora kuba ikibazo ku nsinga ya interineti, aho umurongo uhurira wangiritse, cyangwa igikoresho kidacana.
Icyambu cyo kugerageza:Shyira insinga y'umuyoboro mu yindi port y'igikoresho kugira ngo wirinde ko port yangirika. Niba ihari, ushobora gukoresha icyuma gipima insinga y'umuyoboro kugira ngo urebe aho insinga y'umuyoboro ihurira kugira ngo urebe neza ko buri nsinga yatunganyijwe neza.
Guhuza ikoranabuhanga ni intambwe ya mbere mu itumanaho rya interineti, kandi tugomba kugenzura neza ko nta kibazo kirimo muri uru rwego mbere yuko dukomeza gukora iperereza ku mpamvu zo ku rwego rwo hejuru.
2. Reba uko STP ihagaze kuri Device kugira ngo urebe neza ko Port idafunze
Niba udashobora gukoresha Ping nubwo hari connection isanzwe, hashobora kubaho ikibazo kuri protocole y'urwego rw'ihuza ry'igikoresho. Impamvu imwe ikunze kubaho ni Spanning Tree Protocol (STP).
Sobanukirwa uruhare rwa STP:STP (Spanning Tree Protocol) ikoreshwa mu gukumira kugaragara kwa loops muri network. Iyo igikoresho kibonye loop, STP ishyira ports zimwe na zimwe muri Blocking State, ikazibuza kohereza amakuru.
Reba uko urubuga ruhagaze:Injira muri CLI (Command Line interface) cyangwa Web admin interface ya terefone yawe kugira ngo urebe niba port iri muri "Forwarding". Mu gihe hari Cisco switch, status ya STP irashobora kugaragara ukoresheje command show spat-tree. Iyo port igaragaye nka "Blocking", STP iba ihagaritse itumanaho kuri iyo port.
Igisubizo:
Kuraho by'agateganyo STP:Mu gihe cyo gupima, birashoboka kuzimya STP by'agateganyo (urugero, nta spath-tree vlan 1), ariko ibi ntibyemewe mu ikorwa kuko bishobora guteza inkubi y'umuyaga.
Koresha PortFast:Iyo igikoresho kiyishyigikiye, imikorere ya PortFast ishobora gukurikizwa kuri port (amabwiriza nka spath-tree portfast), bigatuma port isimbuka STP listening and learning phase hanyuma ikinjira mu buryo butaziguye muri forwarding state.
Reba imiyoboro:Niba bloki ya STP iterwa no kuba hari imiyoboro iri mu muyoboro, komeza urebe imiterere y'umuyoboro kugira ngo ubone kandi uce imiyoboro.
Ibibazo bya STP bikunze kugaragara mu miyoboro y'ibigo, cyane cyane mu duce dukoresha uburyo bwinshi bwo guhinduranya amakuru. Niba ufite umuyoboro muto, ushobora gusimbuka iyi ntambwe ubu, ariko gusobanukirwa uburyo STP ikora bishobora gufasha cyane mu gukemura ibibazo mu gihe kizaza.
3. Reba niba ARP ikora kugira ngo urebe neza ko aderesi ya MAC yakemutse neza
Iyo urwego rw'amakuru ari rusanzwe, jya kuri urwego rw'umuyoboro kugira ngo urebe. Itegeko rya Ping rishingira kuri protocole ya ICMP, ibanza gukemura aderesi ya IP igenewe aderesi ya MAC binyuze muri Aderesi ya Aderesi (ARP). Iyo igisubizo cya ARP kinaniwe, Ping izananirwa.
Reba imbonerahamwe ya ARP: Reba imbonerahamwe ya ARP kuri igikoresho kugira ngo wemeze ko aderesi ya MAC y'igikoresho cyagenewe yakemutse neza. Urugero, muri Windows, ushobora kureba cache ya ARP ufunguye umurongo w'amabwiriza hanyuma ukandika arp-a. Niba nta aderesi ya MAC kuri IP y'aho ugana, igisubizo cya ARP cyarananiranye.
Gupima ARP n'intoki:Gerageza kohereza ubusabe bwa ARP n'intoki. Urugero, kuri Windows ushobora gukoresha itegeko rya ping kugira ngo utangire ubusabe bwa ARP, cyangwa ugakoresha igikoresho nka arping (kuri sisitemu za Linux). Niba nta gisubizo cya ARP cyatanzwe, impamvu zishoboka zirimo:
Guhagarika Firewall:Ubusabe bwa ARP buhagarikwa n'insinga z'umuriro z'ibikoresho bimwe na bimwe. Reba Igenamiterere rya firewall y'igikoresho cyagenewe hanyuma wongere ugerageze nyuma yo kuzimya firewall by'agateganyo.
Iterana rya IP:Ubushobozi bwa ARP bushobora kunanirwa iyo habayeho guhurirana kwa aderesi za IP muri network. Koresha igikoresho nka Wireshark kugira ngo ufate paki urebe niba hari aderesi nyinshi za MAC zisubiza IP imwe.
Igisubizo:
Gusiba Arpcache (Windows: netsh interface ip gukuraho arpcache; Linux: ip-ss neigh flush all) hanyuma Ping wongere uyishyire.
Menya neza ko aderesi za IP z'ibikoresho byombi ziri muri subnet imwe kandi ko mask ya subnet ari imwe (reba intambwe ikurikiraho kugira ngo umenye byinshi).
Ibibazo bya ARP akenshi bifitanye isano rya hafi n'imiterere y'urutonde rw'umuyoboro, kandi bisaba kwihangana kugira ngo ukemure ibibazo kugira ngo umenye neza ko byose bikora.
4. Reba aderesi ya IP na Subnet configuration kugira ngo urebe neza ibikorwa remezo by'itumanaho
Ibibazo biri ku rwego rwa network akenshi ni byo nyirabayazana w’ibibazo bya Ping. Aderesi za IP na subnet zitari zo zihari bituma ibikoresho binanirwa kuvugana. Dore intambwe:
Emeza aderesi ya IP:Reba niba aderesi za IP z'ibikoresho bibiri ziri muri subnet imwe. Urugero, igikoresho A gifite IP ya 192.168.1.10 na mask ya subnet ya 255.255.255.0. Ikigo B gifite IP ya 192.168.1.20 na mask imwe ya subnet. Ips ebyiri ziri kuri subnet imwe (192.168.1.0/24) kandi zishobora gutumanaho mu buryo bw'imitekerereze. Niba igikoresho B gifite IP ya 192.168.2.20, ntabwo kiri kuri subnet imwe kandi Ping izananirwa.
Reba udupfukamunwa twa Subnet:Udupfukamunwa twa subnet tudahuza nabyo bishobora gutuma itumanaho rinanirwa. Urugero, igikoresho A gifite mask ya 255.255.255.0 naho igikoresho B gifite mask ya 255.255.0.0, bishobora gutera imbogamizi mu itumanaho bitewe n'uko basobanukiwe neza urwego rwa subnet. Menya neza ko mask za subnet ari zimwe kuri ibyo bikoresho byombi.
Reba Igenamiterere ry'Irembo:Ibikoresho bihujwe mu buryo butaziguye akenshi ntibikenera amarembo, ariko amarembo adakozwe neza ashobora gutuma paki zoherezwa nabi. Menya neza ko amarembo y'ibikoresho byombi ashyizwe ku buryo butakozwe cyangwa yerekeza kuri aderesi ikwiye.
Igisubizo:
Hindura aderesi ya IP cyangwa mask ya subnet kugira ngo urebe neza ko ibikoresho byombi biri muri subnet imwe. Hagarika Igenamiterere ry'inzira ritari ngombwa cyangwa ushyire ku gaciro gasanzwe (0.0.0.0).
Imiterere ya IP ni ingenzi mu itumanaho rya interineti, bityo ni ngombwa kugenzura neza ko nta kintu na kimwe kibura.
5. Reba paki za ICMP zoherejwe n'izakiriwe kugira ngo urebe neza ko Protocole idakingiwe
Itegeko rya Ping rishingira kuri Internet Control Messaging Protocol (ICMP). Iyo paki za ICMP zifashwe cyangwa zifunzwe, Ping ntabwo izageraho.
Reba Amategeko yawe ya Firewall:Ibikoresho byinshi bifite inkuta z'umuriro zifunguye ku buryo busanzwe, zishobora kubuza ubusabe bwa ICMP. Urugero, muri Windows, reba imiterere ya "Windows Defender Firewall" kugira ngo urebe neza ko itegeko rya ICMPv4-In ryemewe. Sisitemu za Linux zigenzura itegeko rya iptables (iptables -L) kugira ngo urebe neza ko ICMP idafunzwe.
Reba Politiki y'Igikoresho:Routers cyangwa switches zimwe na zimwe zifunga ibisubizo bya ICMP kugira ngo hirindwe gushakisha. Injira muri ecran yo gucunga igikoresho kugira ngo urebe neza ko ICMP idakora.
Isesengura ry'ifatwa ry'amapaki:Koresha igikoresho nka Wireshark cyangwaUburyo bwo guhuza imiyoboro ya interinetinaAbahuza ba Mylinking Network Packetgufata amapaki kugira ngo barebe niba icyifuzo cya ICMP cyaratanzwe kandi niba hari igisubizo. Niba icyifuzo cyatanzwe ariko nta gisubizo cyatanzwe, ikibazo gishobora kuba kiri ku gikoresho cyagenewe. Niba nta gisubizo cyatanzwe, ikibazo gishobora kuba kiri kuri mashini yo mu gace utuyemo.
Igisubizo:
(Windows: netsh advfirewall yashyizeho allprofiles state off; Linux: iptables -F) kugira ngo igerageze niba Ping yasubiye ku murongo. Koresha ibisubizo bya ICMP kuri igikoresho (urugero, Cisco device: ip icmp echo-resply).
Ibibazo bya ICMP akenshi bifitanye isano na politiki z'umutekano, zisaba gutandukana hagati y'umutekano n'imikoranire.
6. Reba niba imiterere ya Packet ari yo kugira ngo urebe neza ko nta bintu bidasanzwe biri muri Protocol Stack
Niba byose bigenda neza kandi ukaba udashobora gukoresha Ping, ushobora gukenera gucukumbura muri protocole stack kugira ngo urebe niba paki iri mu buryo bukwiye.
Fata kandi usesengure amapaki:
Koresha Wireshark kugira ngo ufate paki za ICMP hanyuma urebe ibi bikurikira:
- Ubwoko na Kode by'Ubusabe bwa ICMP ni byo (Ubusabe bwa Echo bugomba kuba Ubwoko bwa 8, Kode 0).
- Niba ip z'aho wakuye amakuru n'aho ugana ari zo.
- Niba hari agaciro ka TTL (Igihe cyo kubaho) kadasanzwe gashobora gutuma paki igwa hagati.
Reba Igenamiterere rya MTU:Iyo Igenamiterere rya "Maximum Transmission Unit (MTU)" ridahuye, gucikamo ibice bya paki bishobora kwangirika. MTU isanzwe ni bytes 1500, ariko hari ibikoresho bishobora gushyirwaho agaciro gato. Gerageza gucikamo ibice ukoresheje itegeko rya ping-fl 1472 target IP (Windows). Niba habayeho gucikamo ibice ariko ibendera rya "Do not sharding" (DF) rikashyirwaho, MTU ntabwo ihuye.
Igisubizo:
Hindura agaciro ka MTU (Windows: netsh interface ipv4 set subinterface "Ethernet" mtu=1400 store=persistent).
Menya neza ko MTU y'ibikoresho byombi ari imwe.
Ikibazo cyo gukusanya protocole kiragoye cyane, bivugwa ko isesengura ryimbitse rikorwa nyuma y’uko iperereza ry’ibanze ridafite icyo ritanga.
7. Gukusanya amakuru no gushaka inkunga za tekiniki
Niba intambwe zavuzwe haruguru zidakemuye ikibazo, ushobora gukenera gukusanya amakuru menshi no gushaka ubufasha mu bya tekiniki.
Ikarita:Kusanya amakuru y'ububiko bw'igikoresho (syslog ya router/switch, syslog ya PC) urebe niba hari amakosa.
Vugana n'uwakoze:Iyo igikoresho ari ibicuruzwa by'ikigo nkaKwandika kuri interineti(Gukoresha interineti, Abahuza ba Network PacketnaGucisha mu murongo), Cisco (Router/Switch), Huawei (Router/Switch), ushobora kuvugana n'ubufasha bwa tekiniki bw'uwakoze porogaramu kugira ngo ubahe intambwe zirambuye zo kugenzura no kwandika amakuru.
Gukoresha Umuryango:Shyira ku mbuga za tekiniki (urugero, Stack Overflow, Cisco Community) kugira ngo ubashe gufasha, utange amakuru arambuye yerekeye imiterere y'umuyoboro n'uburyo ukoresha.
Guhuza igikoresho cya interineti bitanyuze kuri Ping bishobora gusa n'aho byoroshye, ariko mu by'ukuri bishobora kuba birimo ibibazo byinshi kuri physical layer, link layer, network layer, ndetse na protocol stack. Ibibazo byinshi bishobora gukemurwa ukurikije izi ntambwe zirindwi, kuva ku zisanzwe kugeza ku zigezweho. Byaba ari ukureba insinga ya interineti, guhindura STP, kugenzura ARP, cyangwa kunoza imiterere ya IP na politiki ya ICMP, buri ntambwe isaba ubwitonzi n'ubwihangane. Nizeye ko iyi nyandiko izaguha ibisobanuro birambuye ku buryo wakora ikibazo cya interineti yawe, bityo ntuzatenguhwa nuhura n'ikibazo nk'icyo.
