Hello,
People who have their names in the Fedora tcp_wrappers changelog added to CC list..
Any comments about the below? Obviously aclexec feature would be useful for all services
using tcpwrappers/libwrap (ftp,telnet,tftp,ident,nfs, and many others),
and thus very nice to have.
Hi
please file a RFE bug on tcp_wrappers. I'll try to use the Debian patch.
I'm going to use the Debian patch adding tcpwrappers support in
openssh-6.7p1 likewise.
