Re: Re: [suse-security] libwrap supported services



Good try guys, BUT...:-)

I tried both rpm and ldd way and got plenty of services listed. After a quick look I could not find either portmap or telnet (both installed on the system), yet I know they are libwrap supported software.

For a fast overview, you can also try
rpm -q --whatrequires libwrap.so.0   ;-)

I guess rpm also doesn't know about them.
