I just created a chroot jail with inetutils, coreutils and bash. Most of the things seem to work. I can ping ip addresses and hosts that are inside
/etc/hosts, however, I can't ping hosts that are not in
/etc/hosts. I copied both
protocols to the chroot jail, but I still cannot ping hostnames. Which file am I supposed to put inside the jail so I can resolve hostnames? I have also read some stuff about
scutil, but I want to avoid copying more binaries as much as possible.
