Asi, usati watanga iyi positi nezve mashandisiro anoshanda evamwe "Linux Commands", tinokurudzira kuti iwe wobva waongorora yapfuura inoenderana posvo yenyaya dzino dzakatevedzana:
Linux Mirairo - Chikamu Chechitatu: netstat, ss uye nc
Kushandisa kushandiswa kwemirairo yeLinux
netstat
Kuraira netstat chishandiso cheCLI chinokutendera kuti utarise zvinongedzo zvenetiweki, matafura enzira, nhamba dzeinterface, masquerade kubatana, uye multicast nhengo yeboka ruzivo. manpages
Mienzaniso yekushandisa iyo netstat command
- Nyora zviteshi zvese: $ netstat --zvose
- Nyora zviteshi zvese zvekuteerera: $ netstat --kuteerera
- Ratidza kuteerera TCP ports: $ netstat --tcp
- Ratidza PID nemazita echirongwa: $ netstat --program
- Ratidza ruzivo pachiratidziro nguva dzose: $ netstat --inoenderera
Kuti uone mimwe mienzaniso yekushandisa uye tsananguro yezvainobatanidzwa sarudzo kana ma paramita, tinya pano.
ss
Kuraira "H.H" is a terminal utility iyo inoshandiswa kuongorora zvigadziko, kureva, kurasa socket statistics pachiratidziro. Naizvozvo, netstat inotariswa zvakanyanya nekuti inogona kuratidza yakawanda TCP uye mamiriro ruzivo. manpages
Mienzaniso yekushandisa iyo ss command
- Ratidza ese TCP/UDP/RAW/UNIX zvigadziko: $ss -a [-t|-u|-w|-x]
- Ratidza ese maTCP sockets akabatana neiyo HTTPS port (443): $ ss -t src :[443]
- Ratidza zvese zvigadziko zveTCP zvinoteerera pachiteshi chemuno 8080: $ss -lt src :[8080]
- Nyora zvigadziko zvese zveTCP pamwe nemaitiro akabatana kune iri kure ssh port: $ ss -pt dst :[ssh]
Kuti uone mimwe mienzaniso yekushandisa uye tsananguro yezvainobatanidzwa sarudzo kana ma paramita, tinya pano.
nc
Kuraira "nc" kana "netcat" murairo unozivikanwa seSwiss knife yeTPC/IP protocol. Sezvo, inobvumira kuverenga nekunyora data kuburikidza netiweki yekubatanidza, uchishandisa TCP kana UDP protocol. Uyezve, inogona kushandiswa zvakananga kana kuburikidza nemamwe mapurogiramu uye zvinyorwa. Uye inoshandawo sechinhu-chakapfuma network yekuongorora uye debugging chishandiso. manpages
Mienzaniso yekushandisa iyo nc command
- Gadzira kubatana kweTCP: $nc[ip_address][port]
- Seta nguva yekupera: $nc -w [timeout_in_seconds] [ipaddress] [port]
- Skena yakavhurika TCP ports yeakapihwa mugamuchiri: $nc -v -z [ip_address] [port]
- Teerera pane yakatsanangurwa TCP port uye printa iyo yakagamuchirwa data: $ nc -l [chiteshi]
- Chengetedza server kumusoro mushure mekunge mutengi abvisa: $ nc -k -l [chiteshi]
- Tumira chikumbiro cheHTTP: $ nc -u -l [chiteshi]
Kuti uone mimwe mienzaniso yekushandisa uye tsananguro yezvainobatanidzwa sarudzo kana ma paramita, tinya pano.
Resumen
Muchidimbu, tinovimba kuti chikamu ichi chechina pa Iyo "Linux Command» kwatakakurukura kushandiswa kwe netstat, ss uye nc mirairo, ramba uchibatsira vashandisi vazhinji kugona iyo Terminal ine simba zvakanyanya sezvinobvira. Uye kana wakamboshandisa imwe yeiyi mirairo mitatu kare, uye iwe uchida kupa chimwe chinhu pamusoro payo, tinokukoka iwe kuti uite saizvozvo. kuburikidza nemashoko.
Pakupedzisira, yeuka kugovera aya mashoko anobatsira navamwe, mukuwedzera kukushanyira musha wedu «website» kuti udzidze zvimwe zvirimo zvazvino, uye ubatane nechiteshi chedu chepamutemo che teregiramu kuti uongorore dzimwe nhau, zvidzidzo uye Linux updates. West boka, kuti uwane rumwe ruzivo nezve musoro wanhasi.
