M\u00e1solni szeretn\u00e9m a remotemachine.net-en a mylogin k\u00f6nyvt\u00e1ramba, de nem szeretn\u00e9m, hogy b\u00e1rki beleszagolhasson a tartalm\u00e1ba. A t\u00e1voli g\u00e9pen SSH-szerver fut. Erre a feladatra az SCP t\u00f6k\u00e9letes, titkos\u00edtott ssh-t haszn\u00e1l.<\/span><\/span><\/p>\n

Eddig a cikk. Egy p\u00e1r apr\u00f3s\u00e1got a magyar szerkeszt\u0151 jog\u00e1n hozz\u00e1f\u0171zn\u00e9k:<\/span><\/p>\n

Nem kell felt\u00e9tlen\u00fcl kitenni m\u00e1sol\u00e1skor a \u201e~\u201d jelet. Ha a g\u00e9p neve (\u00e9s a kett\u0151spont) ut\u00e1n nem \u00edrunk semmit, akkor a t\u00e1voli k\u00f6nyvt\u00e1r a bejelentkez\u00e9si mappa (a home<\/em>) lesz. Ebb\u0151l ered\u0151en m\u00e1s ter\u00fcleteket is el lehet \u00e9rni \u2013 ha van hozz\u00e1f\u00e9r\u00e9si jogunk. \u00cdgy pl. a t\u00e1voli rendszer passwd<\/em> f\u00e1jlj\u00e1t \u00edgy m\u00e1solhatjuk le:<\/span><\/p>\n

scp mylogin@remotemachine.net:\/\/etc\/passwd<\/b> .<\/span><\/p>\n

(A parancs v\u00e9g\u00e9n a \u201e.\u201d azt jelzi, hogy az aktu\u00e1lis [munka] k\u00f6nyvt\u00e1rba helyezze ugyanezen a n\u00e9ven.)<\/span><\/p>\n

Ez a p\u00e9lda is mutatja, milyen fontos a biztons\u00e1g, hiszen ilyen egyszer\u0171en lehet \u201eellopni\u201d fontos, a rendszer szempontj\u00e1b\u00f3l kritikus f\u00e1jlunkat!<\/span><\/p>\n

Az is el\u00e9rhet\u0151, hogy a scp<\/i> \u00e9s az ssh<\/i> ne k\u00e9rjen jelsz\u00f3t, ennek ismertet\u00e9se azonban meghaladja a cikk kereteit. Jelenleg ford\u00edt\u00e1s alatt van egy, ezt a t\u00e9m\u00e1t taglal\u00f3, blog bejegyz\u00e9s.<\/span><\/p>\n

Ahogy a t\u00e1voli g\u00e9p hivatkoz\u00e1sa er\u0151teljesen hasonl\u00edt a b\u00f6ng\u00e9sz\u0151 c\u00edmsor\u00e1ban haszn\u00e1latos kifejez\u00e9sre, \u00edgy a bejelentkez\u00e9s is hasonl\u00edt egy e-mail c\u00edmre. Ez nem csak az scp<\/em> eset\u00e9n haszn\u00e1lhat\u00f3, hanem ugyan\u00edgy lehet az ssh<\/em> parancsban is haszn\u00e1lni:<\/span><\/p>\n

ssh mylogin@remotemachine.net<\/b><\/span><\/span><\/p>\n

Itt viszont nem lehet a g\u00e9p neve ut\u00e1n \u201e:\u201d!<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
