Argh, why don't users understand the concept of stateful firewalls,

user request.  source desktop <-> Server,  bi directional?

I call user,  Asks: do you have a need to ssh to your desktop from the server?
he says he doesn't understand what I am asking.
I ask user if these running a ssh server on his pc?
he says not.
I tell hum I'm cancelling the bidirectional flow since it's not need
(i can see his puzzled look over the phone)

---

another customer asks to open port 8443 to his server  hisserver.mynetwork.com
I respond back request is completed.
he responds back, it's not working and includes the URL to the server http://hisserver.mynetwork.com:9000/web/app

Yes, please can you do the needful and open port 8443 so I can communicate on port 9000?

Gave an instruction to the contingent staff to do some maintenance work on 43 devices that worked great for 40 of them.

On the three it didn't work for, it totally hosed up our guest wireless environment.

:wall: :wall: :wall: :wall: :wall: :wall:

Fixing that now and making a note to never issue broad, all-inclusive instructions again...

now you can understand why we only do 1 task on 1 device per maintenance window.  short windows, lots of verification, time to roll back, and reverify everything.   makes sure nothing else impacts the maintenance, and if something does, it can only be 1 thing.

Think you can probably find a better way to handle things.. that won't a hundred change control windows.   Of course, easy for me to say. 

Why did the same process break three devices while wasn't an issue for the other forty?

40 of the devices needed an *internal* web server cert.
3 of the devices needed an *external* cert, but since I didn't leave them out of the instruction to "get an internal web cert on all these boxes!", they got an internal cert that invalidated the external cert when they had to have their private key regenerated for the internal cert...

As large and complicated that our network is, and the lack of knowledge about who connected what where, and as loud as the customers yell when their stuff goes down, even when we notify them. Best to play it safe.

Code Select
nottherealhostname(config)#crypto key gen rsa mod 4096 gen
The name for the keys will be: nottherealhostname.domain.com

% The key modulus size is 4096 bits
% Generating 4096 bit RSA keys, keys will be non-exportable...
[OK] (elapsed time was 168 seconds)
