Cisco ASA – Port Forward a ‘Range of Ports’
KB ID 0001111 Note: This is for Cisco ASA 5500, 5500-x, and Cisco Firepower devices running ASA Code. This comes up on forums a lot, some applications and most phone systems require a ‘LOT’ of ports to be open. Normally thats fine you just give the internal IP a static public IP and open the ports. But what if you don’t have a spare public IP? I’ve already covered port forwarding before. Cisco PIX / ASA Port...

Exchange – Display Mailbox’s by size
KB ID 0000469 Problem Yesterday a client asked me how he could find out, which of his users were the “worst offenders” for mailbox size. Normally a simple Get-MailboxStatistics command would be fine, and we would sort the results in descending order. Solution On one of the Exchange servers, launch the Exchange Management Shell. Issue the following command: Note: That’s all one command, replace the name PNL-MAIL-2019...

Windows Client(s) not ‘appearing’ in WSUS

No Mail Flow On-Premises To/From Office 365
KB ID 0001631 Problem I upgraded my On-Premises Hybrid Exchange server recently, from Exchange 2016 to Exchange 2019. I remembered to add the new server onto the Office 365 send connector, but there was no mail flow between an on premises mailbox and an office365 mailbox? Solution This happens because, (even if you are using the same certificate on the new and old servers) the certificate that is used for TLS security between your...
Cisco Catalist Upgrading 2900, 5500 and 3700 Stacks
KB ID 0001630 Problem People are often nervous about doing this, I’m not sure why because Cisco have made it painfully simple now. That’s because instead of the old /bin files we used to use, you can now upgrade a switch (or a switch stack) using a .tar file with one command, (and it will also upgrade all the stack members and the firmware on any other network modules you have in the switches at the same time). Yes it does...
XenServer: Enable SNMP
KB ID 0001629 Problem We had to enable SNMP on a XenServer today, I’d never even logged onto one, but it turns out, much like ESX, it’s just a Linux server, at least the good folk at Citrix included nano on there so I didn’t have to struggle with the vi editor! Solution First from the web console ensure that SSH access is enabled > Remote Services Configuration > Enable/Disable Remote Shell. SSH into the host...
