Re: Brute force agains Web Service

It worked.

The IP addresses are showing in the logs, as explained in the page. Now I will work in tuning fail2ban to properly use that information.

Tks.

Brute force agains Web Service

Hi, I know this has been asked before, but I haven't seen a good answer yet. I have a ZCS 8.7 (fully patched) install on Centos 6.10, including zmauditswatch and fail2ban.

You need to set the LC_ALL for the Zimbra user:

export LC_ALL="pt_BR.UTF-8"

Thank you,

I had -147 still installed and booted with that one. It solved the problem. Since uptime is more critical, I will update to -153 in a maintenanc...
