Hostname obtains data using the gethostname(2) call. The /etc/sysctl.conf file is used at startup to set kernel parameters via sysctl(8). The gethostname function does not necessarily use kernel tables. In particular, in glibc implementation, it effectively ignores them, so that the domain returned by `hostname' does not necessarily coincide with the one set by the kernel.domainname parameter. Technically speaking, in glibc, gethostname is a wrapper over uname(2) call, which returns the `nodename' member of the returned struct utsname. Regards, Sergey
