Imwe nguva yapfuura ndaida kuziva dhata pane system chiteshi, kuziva kuti imwe neimwe yaishandisirwei, mashandisiro ayo kana basa, uye ndinorangarira kuti muWikipedia kana imwe saiti ini ndawana chimwe chinhu nezve izvi.
Nekudaro, imwe nguva gare gare ndakazoona kuti ruzivo urwu rwatove mune yedu Linux system, tinayo mufaira: / etc / services
Semuenzaniso, ini ndinokusiira sampuro (uye chete diki sampuro!
ftp-data 20 / tcp
ftp 21 / tcp
fsp 21 / udp fspd
ssh 22 / tcp # SSH Remote Login Protocol

nguva 37 / udp timserver
rlp 39 / udp sosi # nzvimbo yenzvimbo
nameserver 42 / tcp zita # IEN 116
ndiani 43 / tcp zita rezita
Sezvauri kuona, inotiratidza iyo sevhisi kutanga, ipapo chiteshi chainoshandisa, kozoti protocol uye pakupedzisira tsananguro pfupi yemamwe masevhisi.
Vanogona kuratidza zvirimo mufaira iri nekuvhura nechero zvinyorwa zvinyorwa, semuenzaniso mune terminal yavanogona kuisa:
nano /etc/services
Kana kungo nyora faira ne:
cat /etc/services
Kana vasingade KUTI varatidze zvese zvirimo, nekuti ivo vanongoda kuziva (semuenzaniso) ndeipi chiteshi chinoshandiswa FTP, vanogona kusefa nemirairo grep :
cat /etc/services | grep ftp
Uye izvi zvinongotipa izvo zvinoenderana neFTP:
ftp-data 20 / tcp

Zvakanaka izvo. Kuti yedu system inowanzo kuve neruzivo rwatinoda, uye isu hatitomboziva 😀

Enda shamwari yangu, uri mukuru, ndiri kuona kuti wagutsa chikumbiro changu, Ndatenda zvikuru !!!!!, asi ini ndiri kushaya zvimwe, kunyangwe chimwe chinhu chiri nani kupfuura chero chinhu uye ndinoramba ndichimirira mamwe magwaro, ini ndine nzara ruzivo
Kune mamwe magwaro ... mmm zvakanaka, tarisa izvo zvatakaisa apa: https://blog.desdelinux.net/tag/bash/
Nice kuve SElinux yakaitwa: $
SELinux yatove imwe nyaya, zvirokwazvo inokurudzirwa kuti ishandiswe pamwe chete, asi inogona kunge ichikunda dhizaini yemumba (hazvo, izvi zvinoenderana nedanho re "paranoia" remushandisi).
Gaara, shamwari, Hongu, ndatozviongorora izvo, zvese zvakanaka uye ndakazvichengeta, chete kuti ndakasara nechishuwo chekuenderera mberi ndichidzidza mushure me… .kutaura sei… ..kirasi yekutanga kugadzira script uye chii wakaisa here https://blog.desdelinux.net/bash-como-hacer-un-script-ejecutable/
