A nice guide over on the ‘Dummies’ series website. Covers the basics – open/close/save files, edit a file etc.
Very handy, if like me, not a daily user of *nix type systems. All I needed to do was edit resolv.conf on a box to update DNS servers!
Forcing a link state up or down for a vmnic interface on ESXi 5.x
Used this to help work out the physical server’s NIC interfaces had been cabled up to the network switch correctly.
Luckily, the servers DRAC Remote access was working! So via the remote console connection, enabling local support access, downing the NIC and watching the Switch admin interface to trace which port changed. Easy! once I found the commands to down/up nics 🙂
BTW: Problem was VLAN was not assigned to the remote end of the switches uplink trunk.
