Empirically, ib qho kev ua yuam kev tseem ceeb tau pom nyob rau hauv D-Link DGS-3000-10TC hloov (Hardware Version: A2), uas tso cai rau kev tsis lees paub kev pabcuam los ntawm kev xa cov pob ntawv tsim tshwj xeeb hauv network. Tom qab ua cov pob ntawv zoo li no, qhov hloov pauv nkag mus rau hauv lub xeev nrog 100% CPU load, uas tuaj yeem daws tau los ntawm kev rov pib dua.
Thaum qhia txog qhov teeb meem, kev txhawb nqa D-Link tau teb "Zoo yav tav su, tom qab lwm qhov kev kuaj xyuas, cov neeg tsim khoom ntseeg tias tsis muaj teeb meem nrog DGS-3000-10TC. Qhov teeb meem yog vim lub pob tawg uas tau xa los ntawm DGS-3000-20L thiab tom qab kho tsis muaj teeb meem nrog lub firmware tshiab. " Hauv lwm lo lus, nws tau raug lees paub tias DGS-3000-20L hloov pauv (thiab lwm tus hauv cov koob no) rhuav tshem cov pob ntawv los ntawm PPP-over-Ethernet Discovery (pppoed) tus neeg siv khoom, thiab qhov teeb meem no tau kho hauv firmware.
Nyob rau tib lub sijhawm, D-Link cov neeg sawv cev tsis lees paub qhov muaj qhov teeb meem zoo sib xws hauv lwm tus qauv DGS-3000-10TC, txawm hais tias muab cov ntaub ntawv uas tso cai rau qhov tsis zoo rov ua dua. Tom qab tsis kam kho qhov teeb meem, ua kom pom qhov muaj peev xwm ua rau muaj kev tawm tsam thiab txhawb kev tso tawm firmware hloov tshiab los ntawm cov chaw tsim khoom, pcap pob tseg ntawm "pob tuag" tau luam tawm, uas tuaj yeem xa mus kuaj qhov teeb meem. siv tcpreplay utility.
