+============ SSH TUNEL ==================
+Slouzi k tunelovani do vzdalene site a zpristupneni portu na vzdalene siti. Priklad:
+Mame vzdaleny PC s adresou 1.2.3.4, na ktery se dostaneme ssh a ktery je zaroven v siti 4.5.6.0. (ktera je obvykle shovana za natem). A my potrebujeme pristup na webove rozhrani na (dejme tomu) switchi s adresou 4.5.6.7.
+Toho dosahneme tunelem.
+  ssh -L 8080:4.5.6.7:80 1.2.3.4
+Syntaxe:
+  ssh -[LR] localport:remotehost:remoteport host
+L znamena lokalne, tj. ze zpristupnujeme port u nas. Localport je ten, ktery se u nas otevre, remotehost stanice v te vzdalene siti, remoteport je port ktery chceme otevrit, host je ten, na ktery se dostaneme ssh. Tento tunel zpusobi, ze u nas, na localhost:8080 bude otevren 4.5.6.7:80 (cili to zadane rozhrani).
