I-NNCP inketho enhle kakhulu yokushintshana okuphephile kwamafayela, imeyili nokunye

I-NNCP (Ikhodi yeNode iye kuNode) iqoqo lezinsiza ukuthi bakhonza ukudluliswa okuphephile kwamafayela, ama-imeyili nemiyalo ukwenziwa esitolo nasemodini yokudlulisela phambili. Isekela ukusebenza ezinhlelweni izinhlelo zokusebenza ezihambisanayo I-POSIX.

Inzuzo imiselwe ukusiza ukwakha amanethiwekhi amancane kusuka kumngane kuya kumngane (F2F) ngomzila omile wokudluliswa kwamafayela okuphephile kumodi yokukhohlwa umlilo, kanye nezicelo zefayela, i-imeyili, kanye nezicelo zokwenza umyalo Onke amaphakethe adlulisiwe abetheliwe (ukuphela-to-end) futhi aqinisekiswe ngokusobala okhiye bomphakathi abaziwayo.

Ukubethela kufana neTor (u-anyanini) futhi isetshenziselwa wonke amaphakheji aphakathi. I-node ngayinye ingasebenza njengeklayenti neseva futhi isebenzise imodeli yokuziphatha kwe-Push neyokuvota.

Umehluko phakathi kwezixazululo ze-NNCP ne-UUCP ne-FTN (I-FidoNet Technology Network), ngaphezu kokubethela nokufakazela ubuqiniso okukhulunywe ngenhla, Kungukuxhaswa kwebhokisi lamanethiwekhi e-floppin namakhompyutha ahlukaniswe ngokomzimba namanethiwekhi endawo nokungazethembi komphakathi. Isici se-NNCP futhi ukuhlanganiswa okulula (kanye ne-UUCP) ngamaseva wamanje weposi afana nePostfix ne-Exim.

Phakathi kwezicelo ezingenzeka ze-NNCP yinhlangano ye ukuthumela / ukwamukela iposi kudivayisi ngaphandle kwesidingo sokuxhumeka unomphela kwe-inthanethi, dlulisa amafayela ngaphansi koxhumano lwenethiwekhi olungazinzile, ukudluliswa okuphephile kwemininingwane emikhulu kwimidiya ephathekayo, okwenza ukuthi kuvikelwe kumanethiwekhi wedatha ahlaselwe yi-MitM, ngokudlula ekucwaningweni kwenethiwekhi nokubhekwa.

Kusukela ukhiye wokubhala ngokuhumusha utholakala kuphela kumamukeliAkunandaba ukuthi iphakethe lilethwa kanjani kunethiwekhi noma kwimidiya ephathekayo, umuntu wesithathu akakwazi ukufunda okuqukethwe, noma ahlanganyele ukuthunyelwa. Futhi, ukufakazelwa ubuqiniso ngesiginesha yedijithali akuvumeli ukwakhiwa kokuthunyelwa okungamanga ngaphansi kokucasha komunye umthumeli.

Njengamanje i-NNCP isenguqulweni yayo engu-5.0.0, inguqulo lapho kutholakala phakathi kwezinto ezintsha eziphawuleka kakhulu:

• Iphrojekthi ye- Ilayisense ye-GPLv3 + ishintshelwe ku-GPLv3 kuphela, ngenxa yokungathembi i-SPO ngemuva kokuhamba kukaRichard Stallman kuyo.
• Ukubethela kwe-AEAD kuyasetshenziswa igcwele amabhlogo we-ChaCha20-Poly135 128 KiB. Lokhu kuvumela idatha ukuthi iqinisekiswe kumaphakethe abethelwe ngokushesha endizeni, kunokuhluleka ekugcineni kokufunda umbhalo ogcwele.
• Ifomethi yefayela lokumisa ishintshiwe ukusuka ku-YAML kuya ku-Hjson. Umtapo wezincwadi wokugcina ulula kakhulu futhi mncane ngosayizi, ngokulula okufanayo komuntu osebenza ngokumiswa.
• I-zlib compression algorithm efakwe esikhundleni se-Zstandard, lokhu kucabanga ukwanda okuphawulekayo kwejubane lokucindezela ngokusebenza kahle kakhulu.
• nncp-call yanikezwa inketho yokubuka amaphakheji akhona (-list) ohlangothini olukude, ngaphandle kokuwalanda. Ngaphezu kwekhono lokukhetha ngokulanda amaphakheji (ama-pkts)
• i-nncp-daemon ithole inketho -inetd, eyivumela ukuthi isebenze ku-inetd noma, ngokwesibonelo, nge-SSH
• Ukuxhumeka ku-inthanethi kungenziwa hhayi ngqo ngqo nge-TCP, kepha futhi ngokushayela imiyalo yangaphandle nokuxhumana nge-stdin / stdout.
• Imishini evumelana ne-Umask (isebenzisa izimvume ezinwetshiwe ezinjenge-666/777) kanye nekhono lokumisa i-umask emhlabeni jikelele ngefayela lokumisa, lenze lula ukusetshenziswa kwesikhombisi esijwayelekile se-spool phakathi kwabasebenzisi abaningi;
• Ukusetshenziswa okugcwele kwamamojula weGo Go.

Ungayifaka kanjani i-NNCP ku-Linux?

Ukufakwa kwale nsiza kulula, kufanele nje sithembele kuGo isivele ifakiwe ohlelweni futhi ithola inguqulo yakamuva ye-NNCP eyi-5.0.0. Lokhu kungatholakala ku-terminal ngomyalo wget ngale ndlela elandelayo:

wget http://www.nncpgo.org/download/nncp-5.0.0.tar.xz
wget http://www.nncpgo.org/download/nncp-5.0.0.tar.xz.sig
gpg --verify nncp-5.0.0.tar.xz.sig nncp-5.0.0.tar.xz
xz --decompress --stdout nncp-5.0.0.tar.xz | tar xf -
make -C nncp-5.0.0 all

Ngemuva kwalokho bangaqala ngokucushwa, lapho bangathola khona imininingwane edingekayo Kulesi sixhumanisi esilandelayo.

Futhi ekhasini eliyinhloko lelo Kunje:
