I know most Linux network services are linked to libwarp.a (tcp-wrappers) and this can be check via the ldd command. But can't seem to find how to list all the network services being linked to libwarp.a.
After some waiting, I created a dump way myself. Run the script below in /usr/sbin
find ./ -type f -exec echo {} \; -exec ldd {} \; | egrep "\\./|libwrap" | less
Found 5 in CentOS7. Is there a correct way to do this?
