DESCRIPTION
I-Netstat iprinta ulwazi mayelana nesistimu yokuxhumana yenethiwekhi ye-Linux. Uhlobo lwolwazi oluphrintiwe lulawulwa ngxabano yokuqala, kanje:
(akekho)
Ngokuzenzakalelayo, i- netstat ibonisa uhlu lwamasokhethi avulekile. Uma ungacacisi noma yikuphi imindeni yekheli, khona-ke amasokhethi asebenzayo kuwo wonke amakheli ekheli elihleliwe azophrinta.
- vuka, -r
Bonisa amatafula wokuzila kernel.
- amaqembu, -g
Bonisa imininingwane yobulungu beqembu le-multicast ye-IPv4 ne-IPv6.
--interface & # 61; iface, -i
Bonisa itafula lazo zonke izixhumi zenethiwekhi, noma i-interface ecacisiwe ) .
- ukumisa, -M
Bonisa uhlu lokuxhumeka kwe-masqueraded.
- izibalo, -s
Bonisa izibalo zesifinyeto seprotocol ngayinye.
AMAKHONO
- vele, -v
Tshela umsebenzisi ukuthi kwenzekani ngokufaka igama. Ikakhulu ukuphrinta ngolunye ulwazi oluwusizo mayelana nemindeni yekheli elingaguquki.
-numeric, -n
Khombisa amakheli wezinombolo kunokuzama ukuthola isingeniso soguquko, amachweba noma amagama omsebenzisi.
- abakwa-numeric-amabutho
ikhombisa amakheli abanjwe ngamanani kodwa ayithinti ukuxazulula amagama we-port noma yomsebenzisi.
- amarekhodi angamanye amazwe
ikhombisa izinombolo zezinombolo ze-port kepha ayithinti ukuxazulula amagama abanjwe noma abasebenzisi.
abasebenzisi abasebenzisi
ikhombisa ama-ID womsebenzisi wezinombolo kodwa ayithinti ukuxazulula amagama angabamba noma amachweba.
--protocol & # 61; umndeni, -A
Icacisa imindeni yekheli (mhlawumbe ichazwe kangcono njengezinhlelo eziphansi zezinga) okumele kuboniswe kuyo. umndeni uyinhlamba (',') uhlu oluhlukanisiwe lwamagama angukhiye womndeni wekheli njenge- inet , i- unix , i- ipx , i- ax25 , i- netrom , ne- ddp . Lokhu kunomphumela ofanayo nokusebenzisa izinketho ze---inet , --unix ( -x ), --ipx , --ax25 , --netrom , ne --ddp . I- inet yomndeni ikheli ihlanganisa amasokhethi okulandelwayo okuhlaza, we-udp ne-tcp.
-c, - eqhubekayo
Lokhu kuzobangela i- netstat ukuphrinta ulwazi olukhethiwe njalo ngomzuzwana ngokuqhubekayo.
-e, - thumela
Bonisa ulwazi olwengeziwe. Sebenzisa le nketho kabili ngemininingwane esiphezulu.
-o, --timers
Faka ulwazi oluhlobene nama-network timers.
-p, - uhlelo
Bonisa i-PID kanye negama lenqubo lapho isokhethi ngasinye singeyona.
-l, - ukukhetha
Bonisa kuphela izisekelo zokulalela. (Lokhu kukhishiwe ngokuzenzakalelayo.)
-a, - konke
Bonisa kokubili amasokhethi alalela nokungalaleli. Ngenketho ye - infaces , bonisa ukuxhumana okungaziwa
-F
Ulwazi lokuphrinta ukuphrinta kusuka ku-FIB. (Lokhu okuzenzakalelayo.)
-C
Ulwazi lokuphrinta lokuphrinta kusuka kusigcini se-umzila.
ukubambezeleka
I-Netstat izojikeleza ukunyathelisa ngokusebenzisa izibalo zonke imizuzwana yokulibala . UP .
I-OUTPUT
Ukuxhumaniseka okusebenzayo kwe-inthanethi (TCP, UDP, eluhlaza)
I-Proto
Iprotocol (tcp, udp, eluhlaza) esetshenziswe ngesikhwama.
I-Recv-Q
Ukubalwa kwama-byte akukopishiwe ngohlelo lomsebenzisi oluxhunywe kulolu sikhwama.
Thumela-Q
Ukubalwa kwama-bytes akuvunyelwe yi-host host.
Ikheli Lendawo
Ikheli kanye nenombolo ye-port yesiphetho sendawo sesokhethi. Ngaphandle uma okukhethwa kukho -numeric ( -n ) kucacisiwe, ikheli le-socket lixazululwa igama layo lomngane we-canonical (FQDN), futhi inombolo ye-port ihunyushwe egameni lezinsizakalo ezihambelanayo.
Ikheli Lamazwe
Ikheli nenombolo ye-port yesiphetho esikude sokwakheka. I-Analogous ku "Ikheli Lendawo."
Isimo
Umbuso wesisekelo. Njengoba kungekho zimo kumodi eluhlaza futhi ngokuvamile ayikho isetshenziswa esetshenziswa ku-UDP, le kholomu ingashiywa ingenalutho. Ngokuvamile lokhu kungaba omunye wamanani amaningana:
KUSETSHENZISWE
I-socket inexhumano olusungulwe.
SYN_SENT
Isokhethi sizama ngobuqotho ukusungula uxhumano.
SYN_RECV
Isicelo sokuxhuma sitholiwe kwinethiwekhi.
FIN_WAIT1
Isokhethi ivaliwe, nokuxhumeka kuvaliwe.
FIN_WAIT2
Ukuxhumeka kuvaliwe, futhi isokhethi ilinde ukuvala ukuvala ekugcineni.
TIME_WAIT
I-socket ilinde emva kokusondelana ukuphatha amaphakethe asekhona kwinethiwekhi.
KUVALWE
I-socket ayisetshenzisiwe.
CLOSE_WAIT
Ukuphela kokude kuqediwe, kulindeleke ukuthi isibopho sivale.
LAST_ACK
Ukuphela okukude kuqedile, futhi isokhethi ivaliwe. Ilinde ukuvuma.
LALELA
Isixhumi silalela ukuxhuma okungenayo. Izisekelo ezinjalo azifakiwe kulokhu okukhipha ngaphandle uma ucacisa okukhethwa kukho ( -l ) noma -all ( -a ).
UKUVALA
Zombili izisekelo zivaliwe kodwa asinayo yonke idatha yethu ethunyelwe.
AKUNGAZWAZI
Isimo se-socket asiyazi.
Umsebenzisi
Igama lomsebenzisi noma i-id yomsebenzisi (UID) yomnikazi wesokhethi.
Igama le-PID / Uhlelo
I-pair ye-id ye-process id (PID) kanye nenqubo yenkambiso yenqubo eyinhloko. - uhlelo ludala ukuthi le kholomu ifakwe. Uzodinga futhi amalungelo angaphezu kwamandla ukuze ubone lolu lwazi kumasokhethi awunabo . Lolu lwazi lokuhlonza alukatholakali ngamasokhethi we-IPX.
Isikhathi
(lokhu kuzodingeka kubhalwe)
Izixhumi ze-Active UNIX
I-Proto
I-protocol (ngokuvamile i-unix) esetshenziswe yi-socket.
RefCnt
Ukubalwa kwezinombolo (ie izinqubo ezixhunyiwe ngalezi zihloko).
Amafulegi
Amafulegi aboniswe ngu-SO_ACCEPTON (aboniswa njenge- ACC ), SO_WAITDATA ( W ) noma i-SO_NOSPACE ( N ). I-SO_ACCECPTON isetshenziselwa amasokhethi angaxhunyiwe uma izinqubo ezihambelanayo zilindele isicelo sokuxhumana. Amanye amafulege awazona ezithakazelisayo ezijwayelekile.
Thayipha
Kunezinhlobo eziningana zokufinyelela okusiketshezi:
SOCK_DGRAM
I-socket isetshenziswe kumodi ye-Datagram (ukungenaxhunyiwe).
SOCK_STREAM
Lona ukusakaza (uxhumano) isokhethi.
SOCK_RAW
I-socket isetshenziselwa njengesixhumi esiluhlaza.
SOCK_RDM
Lo ukhonza imiyalezo ethembekile-ethunyelwe.
SOCK_SEQPACKET
Lokhu yisixhumi sepakethe esiyingqayizivele.
SOCK_PACKET
Isikrini sokufinyelela esibonakalayo esibucayi.
AKUNGAZWAZI
Ngubani owaziyo ukuthi ikusasa lisiletha kanjani - faka nje lapha :-)
Isimo
Le nsimu izoqukatha enye yezinkomba ezilandelayo:
MAHHALA
Isikingi asikwabiwe
Ukulalela
Isitokisi silalela isicelo sokuxhuma. Izisekelo ezinjalo zifakiwe kuphela ekukhipheni uma ucacisa okukhethwa kukho ( -l ) noma -all ( -a ).
Ukuxhumana
Isitokisi siseduze ukusungula uxhumano.
IQINISWE
Isixhumi sixhunyiwe.
UKUQALA
I-socket ixhuma.
(akunalutho)
I-socket ayixhunyiwe kwenye.
AKUNGAZWAZI
Lesi simo akufanele senzeke.
Igama le-PID / Uhlelo
I-Process Process (PID) nenqubo yenkambiso yenqubo ene-socket evulekile. Ulwazi oluningi olutholakalayo kusigaba se- Active Internet esixhunywe ngenhla.
Indlela
Leli yigama lomzila njengoba izinqubo ezihambelanayo zifakwe esikhwameni.
Amasokhethi asebenzayo we-IPX
(lokhu kudinga kwenziwe ngomuntu owaziyo)
Amasokhethi asebenzayo we-NET / ROM
(lokhu kudinga kwenziwe ngomuntu owaziyo)
Amasokisi AX.25 asebenzayo
(lokhu kudinga kwenziwe ngomuntu owaziyo)
BONA FUTHI
Okubalulekile: Sebenzisa umyalo womuntu ( % umuntu ) ukuze ubone ukuthi umyalo usetshenziswe kanjani kukhompyutha yakho ethile.
