Yadda ake Increara lokacin hutun SSH a cikin Linux

Lokaci na SSH sakamakon rashin aiki na iya zama mai matukar damuwa. Wannan yakan tilasta ka ka sake haɗa haɗin kuma ka sake farawa.

Abin godiya, a sauƙaƙe za ku iya ƙara iyakance lokacin SSH kuma ku ci gaba da zamanku na SSH koda bayan rashin aiki. Wannan na faruwa yayin da ko dai sabar ko kuma abokin harka ya aika fakiti mara ga sauran tsarin don ci gaba da zaman da rai.

Shafi na Karanta: Yadda za a Amintar da Harden OpenSSH Server

Bari yanzu bincika yadda zaka iya ƙara lokacin hutun haɗin SSH a cikin Linux.

Timeara lokacin hutun SSH

A kan sabar, kai tsaye zuwa /etc/ssh/sshd_config fayil ɗin daidaitawa.

$ sudo vi /etc/ssh/sshd_config

Gungura kuma gano wurare masu zuwa:

#ClientAliveInterval 
#ClientAliveCountMax

Sigar ClientAliveInterval yana ƙayyade lokaci a cikin sakan da uwar garken zai jira kafin aika fakiti mara kyau zuwa tsarin abokin ciniki don kiyaye haɗin yana raye.

A gefe guda, saitin ClientAliveCountMax yana bayyana adadin saƙonnin rayayyiyar abokin ciniki waɗanda aka aika ba tare da samun kowane saƙo daga abokin ciniki ba. Idan har aka kai wannan iyaka yayin da ake aika sakonnin, sshd daemon zai sauke zaman, yadda yakamata ya dakatar da zaman ssh.

Ana ba da darajar lokaci-lokaci ta samfurin sigogi na sama watau

Timeout value = ClientAliveInterval * ClientAliveCountMax

Misali, bari mu ce kun ayyana sifofinku kamar yadda aka nuna:

ClientAliveInterval  1200
ClientAliveCountMax 3

Timeimar Lokaci zai zama sakan 1200 * 3 = 3600 sakan. Wannan kwatankwacin awa 1, wanda ke nuna cewa zaman ku na ssh zai kasance rayayye na rashin aikin awa 1 ba tare da faduwa ba.

A madadin haka, zaku iya cimma sakamako iri ɗaya ta hanyar ƙayyade ma'aunin ClientAliveInterval shi kaɗai.

ClientAliveInterval  3600

Da zarar an gama, sake shigar da daemon OpenSSH don canje-canjen ya fara aiki.

$ sudo systemctl reload sshd

A matsayin ma'aunin tsaro na SSH, yana da kyau koyaushe kada a saita darajar lokaci na SSH zuwa babbar daraja. Wannan shine don hana wani yayi tafiya ta hanyar satar zaman ku idan kun tafi na dogon lokaci. Kuma wannan don wannan batun.
