Cisco ASA ‘Ping Source?’
KB ID 0001445 Problem To be honest, the title is a little misleading, on an ASA you can specify which interface to launch a ‘ping’ from, but that’s it. I found myself in a situation today where I was working on a client firewall and I was trying to bring up a VPN tunnel, and I did not have access to any of their machines, and nor did they, (hence the reason for the VPN tunnel!) Well we can’t use good old...

Switch#show inventory...
HP BL460c (Gen 10) Blade No RAID?
KB ID 0001443 Problem While spinning up some new BL460c (Gen 10) blades for a client, I noticed there was no RAID option? They were going to be VMware ESX hosts, and had two SSD drives so I just accepted the default and my ESX server saw a LUN for each drive and I created two DataStores on each host. The client wanted them changing to RAID1 (fair enough) so I revisited the drive setup. Solution WARNING: Before you proceed enabling...

Mac OSX: ‘Cannot Send F11 Keystroke’
KB ID 0001441 Problem I was building some HP blade servers today via iLO, and while trying to install ESX, I reached this stage; Pressing F11 on a mac just increases the volume, and with the other function keys (F1 to F10) you simply press ‘fn’ and the appropriate F key, and it works properly. But not on a mac, ‘Fn+F11’ just shows you your desktop. Even changing function keys in the keyboard settings has no...
vCenter and PSC: IE Content Was Blocked
KB ID 0001440 Problem I’d just installed a new vCenter and Platform Services Controller for a client this week. When I tried to access the web consoles I saw this. Content was blocked because it was not signed by a valid security certificate For information see “About Certificate Errors” in Internet Explorer Help. No amount of allowing certificates without revocation, and tinkering with the registry would let me in?...

PowerShell: Finding Stale User and Computer Accounts
KB ID 0001438 Problem I do this a lot, (usually prior to big migrations), most organisations have no mechanism for removing old users and computers from Active Directory, some don’t even disable the accounts. Find Users Who Have Never Logged On Use the following PowerShell Command; Get-ADUser -Filter { LastLogonDate -notlike “*” -and Enabled -eq $true } -Properties LastLogonDate | Select-Object @{...
vSphere: Open Console Only Opens the Web Console?
KB ID 0001437 Problem At first I simply though this was an IE problem, but I tried with Firefox and Chrome and it was the same. ‘Open Console’ simply opens the web console, and does not offer you a choice any more? Solution They’ve done a great job of hiding it! On the VM’s summary tab, click the options ‘cog’. And theres the options again. If you want to use the VMRC, you will need to download it...
