Esikhathini esithile esidlule bengifuna ukwazi idatha emayelana namachweba esistimu, ukwazi ukuthi ngayinye isetshenziselwe ini, ukusetshenziswa kwayo noma ukusebenza kwayo, futhi ngiyakhumbula ukuthi kwiWikipedia noma kwenye indawo ngithole okuthile ngalokhu.
Kodwa-ke, ngokuhamba kwesikhathi ngithole ukuthi lolu lwazi seluvele lukhona ohlelweni lwethu lwe-Linux, sinalo kufayela: / njll / amasevisi
Isibonelo, ngikushiyela isampula (nesampula elincane kuphela!) Kulokho eliqukethe:
I-ftp-data 20 / tcp
I-ftp 21 / tcp
fsp 21 / udp fspd
ssh 22 / tcp # SSH Protocol Yokungena Ekude
ssh 22 / udp
Inombolo yocingo 23 / tcp
smtp 25 / tcp imeyili
isikhathi 37 / tcp timserver
isikhathi 37 / udp timserver
rlp 39 / udp insiza # indawo yezinsiza
igama le-nameserver 42 / tcp # IEN 116
igama le-whois 43 / tcp
Njengoba ukwazi ukubona, isibonisa insiza kuqala, bese ichweba eliyisebenzisayo, bese kuba umthetho olandelwayo bese ekugcineni kube incazelo emfushane yezinsizakalo ezithile.
Bangakhombisa okuqukethwe kwaleli fayela ngokulivula nganoma yisiphi isihleli sombhalo, ngokwesibonelo esigungwini abangasibeka:
nano /etc/services
Noma umane ufake kuhlu ifayela nge:
cat /etc/services
Uma ungafuni ukukhombisa konke okuqukethwe, ngoba ufuna ukwazi kuphela (ngokwesibonelo) ukuthi iyiphi imbobo esetshenziselwa i-FTP, ungahlunga ngomyalo i-grep :
cat /etc/services | grep ftp
Futhi lokhu kuzosinika ngenxa yalokho okuhlobene ne-FTP:
I-ftp-data 20 / tcp
I-ftp 21 / tcp
tftp 69 / udp
sftp 115 / tcp
I-ftps-data 989 / tcp # FTP ngaphezulu kwe-SSL (idatha)
I-ftps 990 / tcp
venus-se 2431 / udp # udp sftp side effect
codasrv-se 2433 / udp # udp sftp side effect
gsiftp 2811 / tcp
gsiftp 2811 / udp
i-frox 2121 / tcp # frox: i-caching ftp proxy
i-zope-ftp 8021 / tcp # ukuphathwa kwe-zope nge-ftp
Kulungile lokho. Ukuthi uhlelo lwethu luvame ukuba nolwazi esiludingayo, futhi nathi asazi 😀
Phendula ngokucaphuna
Kunconywa njalo cha sebenzisa amachweba azenzakalelayo. Uma umuntu ongafuneki ezama ukuxhuma nge-ssh, itheku lokuqala abazolisebenzisa kuzoba ngu-22. Okufanayo kuzokwenzeka ngetelnet (ngicabanga ukuthi akusekho muntu oyisebenzisayo xD).

Kodwa-ke, kungenzeka ukuthi uthole ukuthi iyiphi insiza esetshenziswayo.
Vele, akunconywa ukusebenzisa amachweba azenzakalelayo, okungenani hhayi kuzo zonke izinsizakalo. Isibonelo sakudala yi-SSH, okusobala ukuthi noma ngabe kunezinqubomgomo ezifanele ku-firewall, kuhle ngaso sonke isikhathi ukushintsha itheku. Sesivele sichaza lokho lapha: https://blog.desdelinux.net/configurar-ssh-por-otro-puerto-y-no-por-el-22/
Hamba mngani wami, umuhle, ngiyabona ukuthi usenelisile isicelo sami, ngiyabonga kakhulu !!!!!, kepha ngilahlekelwe kakhulu, yize kukhona okungcono kungelutho futhi ngilokhu ngilinde eminye imibhalo, ngilambele ulwazi
Ukuthola eminye imibhalo ... mmm kahle, hlola lokho esikubeke lapha: https://blog.desdelinux.net/tag/bash/
Kuhle ukuthi kusebenze i-SElinux: $
I-SELinux isivele ingolunye udaba, ngokuqinisekile kunconyelwe ukusetshenziswa kwezinkampani, kepha kungahle kube ngaphezu kwamandla wohlelo lwasekhaya (kahle, lokhu kuya ngezinga le- "paranoia" lomsebenzisi).
UGaara, mngani, Yebo, sengikubuyekezile lokho, konke kuhle kakhulu futhi ngikugcinile, kuphela ukuthi bengisele nesifiso sokuqhubeka nokufunda ngemuva… .ukusho kanjani… ..ikilasi lokuqala lokwenza iskripthi futhi ufake ini https://blog.desdelinux.net/bash-como-hacer-un-script-ejecutable/
ncamashi izinsuku ezingama-261 ezedlule ... hehehe ... bengicabanga ukuthi ngizoqhubeka ngokulandelana noma ngokulandelana ukuze ngiqhubeke nokufunda, nje lokho.
Ngemuva kwalokho ngafaka eyodwa ezimweni zokuthi-ke-okunye, kubheke lapho kukhona.
Qhubeka ubhale i-athikili ngokusetshenziswa kwamacala, kuyasiza kakhulu (angizenzi ngokwami ngenxa yokushoda kwesikhathi, uxolo). Ngendlela, awungitshelanga ukuthi enye indlela engikuthumele yona kusikripthi sokuthola i-distros ikwenzile okuhle.
Kungukuthi ngigcine ngipakisha nje .DEB futhi yilokho, ngigcine leyo hahaha, futhi umngani (son_link) uzoyipakishela i-Arch, futhi ngizobona ukuthi ngifunda kanjani ukupakisha .RPM 🙂
Yebo yebo, kungisebenzele kahle, ngifunde okuthile okusha hehehehe.
Siyabonga ngokwabelana ngethiphu! Iya kumardardres ami.
Ozithobayo. 🙂
Ngiyabonga ngokuphawula 😀
ngiyabonga ngolwazi
Kungamachweba ayi-1000 xD
Kepha nge-nmap ekhomba ku-static ip yethu, lezo ezisebenzayo azisitholi futhi kukhona okungangena lapho?
Isibonelo i-armitage isebenzisa i-nmap ukulandelela izimbobo
Phendula ngokucaphuna
Yebo, nge-nmap ungazi amachweba avulekile kukhompyutha 🙂
Icebo elihle, ukuphawula nje, asikho isidingo sokufaka ikati nge-grep.
grep ftp / etc / services
