Logging & Syslog scripts not working

Hello everyone! :slight_smile: I’m new to the forum (but not to mikrotik products) and I’m now configuring the Logging & Syslog as I saw in this guide http://wiki.mikrotik.com/wiki/Securing_New_RouterOs_Router#Port_Knocking
The problem is that when I put in the terminal the line

 /system logging action add target=disk disk-lines=300 name=FirewallHits

( I have choosen 300 as max lines to store) the terminal says to me that there is already a disk action with such name file. So it fails.
Going further, when I put the command

 /system logging add topics=firewall action=FirewallHits

the terminal says to me that input does not match any value of action.
What should I do?
Also, I did not understand this:
“Under *nix-like OS you should do that (FreeBSD, for example):” etc…
Should I do something similar even if I’m under windows 7?
Thanks :slight_smile:

Help please! :frowning:

Up :frowning:

Have you tried to do this via the GUI ?

Nope, if you think that it might works, i’ll try. Will take time, but ok.
Do you think changing the filename could works?

Not working, not even if i change the file name in the code line :frowning:
