TTL - Yini lokhu?

TTL - Kuyini? TTL imele Isikhathi Live. Okungukuthi, isikhathi ukuphila, eyabelwa kuye okwamanje sokushintshela kusukela engeyokuqala kokuqala kuze kube sekupheleni. Ngo-IPv4 TTL ejwayelekile esabelwe kubonise ayisishiyagalombili-bit ensimini enhlokweni. Kudlulwa ISIZINDA amaningi iphakethe uya khona njalo ukubaluleka incipha ngo eyodwa. Lokhu kwenziwa ukuze kukhawulwe nesikhathi sokuba khona kwakhe ngaleso ISIZINDA yenombolo ethile. Futhi lokhu, esikhundleni salokho, ikuvumela ukuba ugweme kokuminyaka amanethiwekhi.

Njengoba kuhlelwa kobuchwepheshe abalobi isikhathi ukuphila ulahlekelwe 1 iphuzu ngomzuzwana. Kodwa sibonga okusezingeni eliphezulu yesivinini sokuxhuma kanye nenani router ISIZINDA nokwehlisa senzeka isheshe.

Kwenzakalani uma TTL sifinyelela zero? Iphakheji uzonyamalala futhi umthumeli uzothola umlayezo othi isikhathi sakhe ekuphileni, ngakho-ke kudingeka uzame futhi. Inani esiphezulu ukuthi uyakwazi ukubonisa ayisishiyagalombili-bit inkambu 255. ihambisane amagugu okuzenzakalelayo for uhlelo lokusebenza. njengoba TTL njalo is 128 e-Windows Linux nemikhiqizo - Mac, i-Android - 64.

Imvelo unendlela yawo DNS TTL, futhi ibonisa ukuphuthuma idatha ezilondolozwe isikhashana. Kodwa mbuzo esihlokweni akuyona ngaye.

Kungani usebenzisa TTL nezindawo zomphakathi

ukuphila Iphakheji ngenkuthalo ukusebenzisa ezahlukene Internet Service Providers, ezifana Yota. Ngakho, abazama Sinqanda ukufinyelela emininingwaneni ukusetshenziswa traffic ngokweqile ekusakazeni-Wi-Fi. Lokhu kwenzeka ngenxa yokuthi iphakethe uya kusuka kudivayisi ukuthi uthola i-traffic Sabalalisa, kunciphisa TTL, ekugcineni kuziwa umhlinzeki kuncane noma esimweni se-Windows kunaleso esilindelekile.

Ngokwesibonelo, singakwazi ukuchaza inqubo imisebenzi smartphone ngesisekelo "Android". Idivayisi ithumela isicelo idatha kusuka endaweni ebekiwe. Naye ithunyelwa TTL, ogama value kuyinto 64. Umhlinzeki uyazi ukuthi lobu indinganiso kulesi sikhathi isibalo kudivayisi iphakethe zokuphila, ngakho-ke kukuvumela ukuthi ufinyelele ngokukhululekile Web.

Manje, idivayisi iqala ukusabalalisa-Wi-Fi bese kuba uhlobo router. Xhuma smartphone yakho egijima emsamo-Windows, kanye TTL, edabula Hrazdan kudivayisi 127. Umhlinzeki uzohlangana lokhu iphakethe futhi uyaqonda ukuthi kwasakazwa inthanethi. Ngakho-ke, i-sodinenenie block.

Amathuba TTL izinguquko kumadivayisi amaningi

Ukushintsha ukubaluleka kwempilo iphakethe kungaba wusizo yokuwuthola Ukuvinjwa traffic umhlinzeki. Ngokwesibonelo, uma ufuna ukucima uxhumano ikhebula, futhi umsebenzisi kudingeka ngokuphuthumayo uthole ku-intanethi kusuka kwikhompyutha yakho. Lapho smartphone iba indawo yokungena, bese ivuka computer kwinethiwekhi.

Kuyaphawuleka ukuthi abanye abahlinzeki ukuvimba ukufinyelela hhayi kuphela TTL, kodwa futhi nizibhale site ukuvakashelwa. Futhi uma ukuphila akuhlangene ne-smartphone, isb. E. Akudingeki ke, ukuxhumana kuwa.

Shintsha TTL ngezindlela eziningana, okuyinto uzobe kuchazwe ngemuva kwalokhu.

Ukushintsha TTL kumadivayisi platform "Android"

Indlela elula ukushintsha kwempilo iphakethe kumadivayisi "Android" kungaba ukusetshenziswa software ezikhethekile. Ngokwesibonelo, umkhiqizo ephumelela kakhulu - TTL Master. Ungashintsha okwamanje amaphasela ukuphila kudivayisi, okuyinto etholakala ngenxa ukudlula idatha. Ngokwesibonelo, ngo-ukusatshalaliswa kwe-Wi-Fi idivayisi Windows kudingeka isethwe 127, futhi ku-Android noma i-Linux - 63.

Ezinye izinguqulo ngesinqumo lutholakala ngokusebenzisa iptables, ngoba lapho kukhona iphuzu elithile.

In the izilungiselelo kungenzeka ukusetha isiqalo futhi ushintshe isikhathi ukuphila ngokuzenzakalelayo lapho amabhuzu kudivayisi. Ezinye izinguqulo "Android" ikuvumela ukuthi wenze isiqalo emva kokushintsha ukubaluleka yokungena. Kukhona usekelo isiRashiya.

Uhlelo lokusebenza njalo namatemu ekuthuthukiseni. Kukhona iphrofayela kwi github, lapho wonke umuntu angakwazi azikhandle ukungeza amakhono ayo le phrojekthi. Uma amukela, onjiniyela, bayoba zifakwe ukukhululwa okwalandela.

Ungazama futhi indlela izinguquko ifayela uhlelo ngesandla ukushintsha isikhathi value iphakethe ukuphila. Lokhu kuzodinga impande-amalungelo. Okokuqala kufanele ukuya ye-flight mode, okungukuthi ukuqinisekisa ukuthi ifoni ilahlekelwa inethiwekhi.

Khona-ke ukusizakala yisiphi isiqondiso okwaziyo ukuhlela amafayela. Kuyadingeka ukuba uhambe endleleni proc / SYS / net / IPv4. Kulesi ikhathalogi unesithakazelo ifayela okuthiwa ip_default_ttl. Iqukethe 64 ishintshwe ukuze 63.

Okulandelayo udinga ukuletha ifoni aphume ye-flight mode, kangangokuba waphinde + bhalisiwe e inethiwekhi. Manje ungasabalalisa inthanethi wireless bese uyazama ukuxhuma idivayisi ye-iOS noma "i-Android" okungukuthi, nge TTL 64.

Uma ufuna ukuyisebenzisa njenge-PC klinetov ne-Windows, uzodinga ukusetha unomphela ukuphila konke indlela ukupakisha, njengoba kuchaziwe ngezansi.

Ukushintsha TTL kwikhompyutha nge-Windows wokusebenza

Uma ufuna ukusabalalisa i-Inthanethi kusuka smartphone "Android" kukhompyutha esebenzisa i-Windows, kufanele ulungise kancane yenani ebhukwini. Le ndlela uyobe ephila uma ifoni akanawo uRuthe no ukundlula ingidi kungaphumeleli.

Running a ebhukwini wohlu wokusebenza bungatholakala ngokusebenzisa into "Qala" imenyu "Gijima." Kumele ufake regedit bese ucindezela OK. Ku-window ezovela zindawo ezimbili ayifani. Ngakwesokunxele isakhiwo esihlahleni, futhi ilungelo - value. Udinga ukuthola igatsha HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Amapharamitha. Tcpip-Windows 8 ungayithola enye by Tcpip6.

Njenganoma amagugu ezidingekayo ukudala ewindini elisha. Lokhu kwenziwa ngokuchofoza ngakwesokudla. On imenyu yamashothikhathi, ukhethe "Entsha" ke ipharamitha elisha DWORD, sanikwa TTL igama Okuzenzakalelayo. Kuyini lokhu? Lena kulungiselelwa static kunani njalo isikhathi ekuphileni. Bese uchofoza kwesokudla futhi ukhethe "Shintsha". uhlobo inani kumelwe abe idesimali, kanye ukubaluleka - 65. Ngako-ke, uhlelo batawedlulisela isikhathi ukuphila kuya 65, okungukuthi omunye ngaphezulu kakhulu 'ze-Android ".
