"hostname" question during Debian installation
During Debian installation there is a question about "hostname" using
expert installation mode.
Am I correct, that "hostname" inserted during Debian installation is
associated with a local(address from 127.0.0.0/8 range) IP address:
martin@martin-ThinkPad-T60:~$ grep martin-ThinkPad-T60 /etc/hosts
::1 martin-ThinkPad-T60 localhost6.localdomain6 localhost6
..and it's used by few software programs(for example Apache, MySQL),
but hostname is usable only locally and not reachable from any other
machine even inside the LAN? In addition, aren't most of the programs
using 127.0.0.1 address which is mapped to "localhost" in /etc/hosts
file not to hostname I set:
martin@martin-desktop:~$ sudo netstat -lnpt
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address
State PID/Program name
tcp 0 0 127.0.0.1:8118 0.0.0.0:*
tcp 0 0 127.0.0.1:631 0.0.0.0:*
tcp6 0 0 ::1:631 :::*
If yes, then changing the hostname shouldn't break any
services/programs associated with it?
All the explanations and clarifications are most welcome!
