SSH birikmelerini näsazlyklary düzetmek üçin SSH düzediş tertibini nädip açmaly

Bu makalada Linux-da SSH işledilende düzediş tertibini nädip açmalydygyny görkezeris. Söz buýrugyny ýa-da düzediş tertibini ulanyp, uzakdaky Linux serwerine birikmek üçin ssh buýrugyny ýerine ýetireniňizde hakykatdanam nämäniň bolup geçýändigini görmäge mümkinçilik berer.

[Şeýle hem halamagyňyz mümkin: Linux-da SSH birikmelerini çaltlaşdyrmagyň 4 usuly]

Ssh müşderisiniň -v wyklýuçateli, SSH birikmesiniň ösüşi barada düzediş maglumatlary çap edýän, baglanyşyklary, autentifikasiýany we islendik konfigurasiýa meselelerini düzetmek üçin hakykatdanam peýdaly bolan ssh işleýiş tertibinde işlemäge mümkinçilik berýär.

Dürli sözler bar; birnäçe -v baýdaklary ulanmak sözliligi ýokarlandyrýar (iň ýokary söz derejesi 3).

ssh -v - esasan ahyrynda nämeleriň bolup geçýändigini size habar berer.
ssh -vv - iki ujunda pes derejäni habar berer.
ssh -vvv - iki ujundan hemme zat barada size habar berer.

Aşakdaky buýruk, görkezilişi ýaly köp düzediş maglumatlary berýän sözleriň birinji derejesinde SSH işleder.
