Mam laptopa z systemem Windows 7 i zainstalowaną VMWare Workstation 9. Używam stacji roboczej do uruchamiania dwóch maszyn wirtualnych RHEL6. Mogę ssh do mojej pierwszej maszyny wirtualnej z laptopa, ale nie ma problemu, ale jedynym sposobem, w jaki mogę ssh do mojej drugiej maszyny wirtualnej, jest najpierw ssh do mojej pierwszej maszyny wirtualnej, a następnie ssh do drugiej maszyny wirtualnej. Nie mogę ssh bezpośrednio z mojego laptopa na drugą maszynę wirtualną. Nie rozumiem dlaczego. Każda pomoc jest mile widziana.
Pierwsza maszyna wirtualna ma adres IP 192.168.204.129 ...
