KEV POM ZOO
Netstat luam tawm cov ntaub ntawv hais txog qhov kev sib tshuam Linux hauv subsystem. Hom kev qhia luam tawm yog tswj los ntawm thawj kev sib cav, raws li nram no:
(tsis muaj)
Los ntawm vim, netstat qhia txog ib daim ntawv teev cov chaw qhib. Yog tias koj tsis qhia meej txog txhua qhov chaw nyob ntawm tsev neeg, ces cov chaw nyob ntawm txhua qhov chaw nyob yuav tsum luam tawm.

qhia cov chaw nyob rau hauv cov zauv suav tiam sis tsis ua li cas rau qhov chaw nres nkoj lossis tus neeg siv npe.
- chaw naj npawb
qhia tias muaj pes tsawg tus xov tooj hauv chaw nres nkoj tiamsis tsis cuam tshuam txog kev daws teeb meem ntawm tus tswv tsev lossis tus neeg siv npe.
- cov neeg siv-cov neeg siv
qhia tias neeg siv tus lej ntawm cov neeg siv suav tiam sis tsis cuam tshuam txog kev daws teeb meem ntawm tus tswv tsev lossis lub npe ntawm lub npe.
- Kev cai & # 61; tsev neeg, -A
Qhia meej rau cov tsev neeg qhov chaw nyob (tej zaum zoo dua piav raws li cov txheej txheem qis tshaj) rau cov kev sib txuas uas yuav tsum tau ua. tsev neeg yog ib qho vias (',') cais cov npe ntawm tsev neeg cov lus tseem ceeb xws li inet , unix , ipx , ax25 , netrom , thiab ddp . Qhov no muaj cov nyhuv tib yam li siv cov --inet , -unix ( -x ), --ipx , --ax25 , --netrom , thiab --ddp kev xaiv. Qhov chaw nyob hauv tsev neeg muaj xws li nqaij nyoos, udp thiab tcp raws tu qauv.
-c, -continuous
Qhov no yuav ua rau netstat luam tawm cov lus qhia xaiv txhua thib ob tsis tu ncua.
-e, --extend
Tso saib cov lus qhia ntxiv. Siv qhov kev xaiv no ob zaug rau kev nthuav dav tshaj.
-am, -timers
Muab cov lus qhia ntsig txog cov sijhawm sib tham.
-p, - tshuab
Qhia PID thiab lub npe ntawm qhov kev zov me nyuam uas txhua qhov qhov ntsej muaj.
-l, - mloog
Qhia tsuas yog mloog cov chaw nyob. (Cov no yog rho tawm ntawm lub neej ntawd.)
-a, - ib qho
Qhia ob qho tib si mloog thiab cov uas tsis mloog. Nrog rau - kev xaiv chaw, pom cov cim uas tsis muaj cim
