Muchinyorwa chinotevera ticha tarisa maitiro atingaite tsvaga madoko ekuteerera pane yedu Ubuntu system. Kuziva kuti ndeapi mapareti ari kushandiswa muhurongwa ibasa rakakosha kune chero maneja, zvese kana uchigadzirisa nzvimbo uye kana uchidzivirira pakurwisa, mitsara inotevera inogona kubatsira.
Kana iwe uri maneja, iwe unozoziva kuti maseva akagadzirwa kuti ruwanikwe neruzhinji achave nemasevhisi ayo anoteerera pazviteshi zvakapihwa kuti zviite kutaurirana Aya mamiriro anokonzera madoko asiri kushandiswa kuti arambe akavhurika kana kuteerera mune dzimwe nguva, izvo zvinogona kukonzera vamwe kutsvaga kushandisa mamiriro acho.
Isu tinokwanisa kuona network mapoti nenhamba yavo, inosanganisirwa IP kero uye nemhando yekutaurirana protocol (TCP kana UDP). Mune yedu Ubuntu system isu tinokwanisa kuwana mimwe default mirairo yatinogona kushandisa kwairi tarisa komputa yedu kuti uwane open ports.
Matanho atinozoona anotevera anoratidza mimwe mirairo yekuwana mateki ekuteerera. Kuti uvazive muUbuntu, iwe unofanirwa kungotevera imwe yeanotevera matanho:
Tsvaga iwo akavhurika madoko (ekuteerera madoko) muBuntu
Uchishandisa iyo netstat yekuraira
Ichi tambo yekuraira chishandiso icho inogona kutipa ruzivo rwakanangana ne IP kero, netiweki yekubatanidza, zviteshi uye masevhisi izvo zvinotaurirana mumadoko aya.
Kana iwe usina ichi chishandiso chakaiswa muUbuntu, iwe unozogona kuchibata icho nekuvhura terminal (Ctrl + Alt + T) uye uchishandisa rairo:
sudo apt install net-tools
Kuiswa kwapera, kana tichida nyora madoko anowanikwa pane server, mhanyisa unotevera kuraira:
sudo netstat -plnut
Mushure mekuita rairo pamwe chete nesarudzo dzakapfuura, isu tinofanirwa kuona chimwe chinhu chakafanana neinotevera pachiratidziri:
Sarudzo dzatinoshandisa mumutemo wekare dzichava dzinotevera:
- -p Inotaridza iyo PID.
- -l Ticharatidza chete anoteerera madoko.
- -n Iyo ichatiratidza nhamba dzemahara pane kugadzirisa mauto.
- -u Ratidza madhipatimendi eDP.
- -t Ratidza TCP zviteshi.
Panyaya yekuda tarisa chete rakatarwa zita rebasa kana chiteshi, Tinogona kushandisa rairo mune iyo terminal netstat nesarudzo dzataishandisa mumutemo wapfuura, apo isu tichizoshandisa zvakare grep.
sudo netstat -plnt | grep :139
Uchishandisa iyo lsof raira
Ichi ndicho chimwe chinozivikanwa Unix-senge anoshanda masisitimu ekuongorora mudziyo, iyo inoshandiswa kuratidza ese mafaera e disk ayo anochengetwa akavhurika nemaitiro, kusanganisira akavhurika network masokisi nemapombi, pakati pemamwe marudzi.
Kuraira lsof chimwe chinhu chinowanikwa, icho chatichakwanisa kumhanyisa muUbuntu terminal uye iyo izvo zvinotibvumidza isu kuti tione iyo network ruzivo. Kunyora ese TCP madoko ari kuteerera, isu tichafanira chete kushandisa iyo lsof yekuraira, ichiperekedzwa nesarudzo dzinotevera:
sudo lsof -nP -iTCP -sTCP:LISTEN
Uchishandisa iyo ss raira
Nokusingaperi netstat haina kuiswa paUbuntu, asi tinogona kuwana rairo iripo ss iyo yakaiswa seinotsiva netstat. Sezvo netstat, iwo wekuraira ss yaishandiswa kuratidza ruzivo rwe network pamusoro peGnu / Linux masisitimu. Ivo vaviri vanogovana ingangoita imwecheteyo yekuraira sarudzo, saka kuti utarise inoteerera madoko, zvese zvaunofanirwa kuita kuvhura terminal (Ctrl + Alt + T) uye nyora mairi:
sudo ss -plnut
Kuburitswa kwemirairo yapfuura, sepakutanga nemutemo we netstat, kunofanira kutiratidza chimwe chinhu chakafanana neiyo inotevera skrini
Kana iwe ukazvipira iwe kuti utungamirire sevha kana uri webmaster uye iwe unoda kuve nechokwadi icho chete anodiwa madoko akavhurika pane yako Ubuntu server, nhanho dzatichangobva kuona dzinogona kubatsira kana uchitsvaga ekuteerera madoko asiri kushandiswa uye anogona kuisa njodzi.
