F\u00f6r det tredje, idag \u00e4r kryptering av kopplingar n\u00e4stan alltid aktiverad som standard i alla DC-klienter.<\/p>\n

\nDC++ avvisar kategoriskt s\u00e4kra kopplingar p\u00e5 NMDC-hubbar, men godk\u00e4nner vanliga. Utvecklarna har p\u00e5pekat orsaken flera g\u00e5nger - det finns ingen anledning att g\u00e5 p\u00e5 gamla spikar!<\/p>\n

StrongDC++ kan bara TLS v.1.0, och moderna klienter kopplar \u00f6verhuvudtaget inte upp sig med det. Med GreylinkDC++ \u00e4r det \u00e4nnu v\u00e4rre.<\/p>\n

Slutsatser<\/b><\/p>\n

L\u00e4saren kan tycka att det b\u00e4st \u00e4r att anv\u00e4nda FlylinkDC++ och inte ha n\u00e5gra problem, men ni gl\u00f6mmer att denna klient \u00e4r problematisk<\/a><\/noindex> i sig.

Som ett resultat av m\u00e5nga historiska och politiska sk\u00e4l \u00e4r anv\u00e4ndningen av NMDC-hubbar som bas f\u00f6r s\u00e4kra mellan-klientf\u00f6rbindelser komplicerad eller helt om\u00f6jlig. Genom att anv\u00e4nda NMDC-hubben kan du med s\u00e4kerhet f\u00f6rlora m\u00f6jligheten att koppla upp dig mot vissa anv\u00e4ndare, och ist\u00e4llet f\u00e5 s\u00e4kerhet \u2013 men utan garantier.<\/p>\n
