ifconfig usually residence in /sbin (some GNU/Linux distribution are in the
migration path of moving it to /usr/sbin), this directory is never in a
normal users or a daemon users $PATH, so you need to give the whole path to
this binary to be able to run it.

By default the file is executional by all users, but someone may have changed
permissions or setup ACL rules with for example SELinux.
