DevNull43 commented on FTPSERVER-349:
-------------------------------------
I just found a problem with current implementation.
I made a copy from BlackListFilter to WhiteListFilter, however when NioListener
starts the filter even if not set:
// add and update the whitelist filter
acceptor.getFilterChain().addLast("allowIpFilter", new
WhitelistFilter());
updateWhitelistFilter();
It does the same for BlackListFilter, however for BlackList setting an empty
array means allow ALL.
However for WhiteList setting a empty array means BLOCK all.
I thought adding subnet 0.0.0.0/0 will allow all host, but is not working.
The only solution would be not to start WhiteListFilter based on some boolean.
Any hints?
