SG300-10 MAC ACL help please! -2
What I want to achieve, it's don't allow that specific mac addresses on switch and deny all others by using MAC ACE.
My periods are as below; What's wrong? It does not have specific host! 00:00:00:00:00:00 generic mask is correct for the host?
Action Source Destination Mask
allow any 00:00:00:00:00:00 ab: cd:ef:aa:bb:cd(Host_MAC)
license ab: cd:ef:aa:bb:cd(Host_MAC) (mask:00:00:00:00:00:00) any
deny any any
Thank you.
Hello
Well, I'm wonfering if the device of interest must at layer 2 to get an IP address for that this referred to MAC address ARP has a static IP address?
I tried and got the following results;
My first entry is to deny access from Layer 2 to my NAS to 192.168.20.61 - ping failed.
My second entry allows me to manage my switch SG300 - 10 p 192.168.20.200 - successful ping
My third invisible entry is probably that implied all refuse it.
So my ping to internet 4.2.2.1 address failed
My attempt to ping my router gateway to 192.168.20.1 also failed.
I still have to worry about ARPing at layer 2. But the result is my filters worked, I think that pings in the screenshot below shows that.
I kept it simple, just applied my MAC ACL filter to the port connected to my PC and not all ports.

Another question, some Mp3 files appear on the "rocket" but do not play. The "rocket" ignores the files about 50 who play very well on the computer. Why is this?
The Zip file is not specific to the platform. The way I unzipped stuff on my old Mac OS (granted, I was using the old OS 9, so it may be different for you) was using StuffIt Expander. If you do it this way, you should be fine.

PROBLEM SOLVED! and I feel so stupid, but maybe this will help others. I had downloaded Firefox 36.0 and it was in my applications folder, BUT I kept clicking on the old icon Firefox so still grown 16.0. All this time and I just needed to get out the new icon on the dock and remove the old. Thanks for those who have tried to help me.

I'm a new mac user. Successfully transferred all of the files from my PC to MacBook pro. All of this is to be seen in the documents. Opened now MacBook and only one file to be seen in 'documents. Where can I find the others. Convinced they are there somewhere, help please.
The Mac is in itself a system multi-user, whether you choose to create a user or a large number.
All users you already created can be seen in
System Preferences > users & groups
The files for each user are kept separated, protected of the subdirectories of the Directory/Users:
/ Users
your User_short_name folder
file user_short_name to your spouse
record your child User_short_name
record your dog user_short_name
