13 How to get the host full name in perl on multiple operating systems
14 (mac, windows, unix* etc)
15
17 This is the SECOND release of this code. It has an improved set of
18 tests and improved interfaces - but it is still often failing to get a
19 full host name. This of course is the reason I wrote the module, it is
20 difficult to get full host names accurately on each system. On some
21 systems (eg: Linux) it is dependent on the order of the entries in
22 /etc/hosts.
23 To make it easier to test I have testall.pl to generate an output list
25 of all methods. Thus even if the logic is incorrect, it may be possible
26 to get the full name.
27 Attempt via many methods to get the systems full name. The
29 Sys::Hostname class is the best and standard way to get the system
30 hostname. However it is missing the long hostname.
31 Special thanks to David Sundstrom and Greg Bacon for the original

36 This is the original list of platforms tested.
37 MacOS Macintosh Classic OK
39 Win32 MS Windows (95,98,nt,2000...)
40 98 OK
41 MacOS X Macintosh 10 OK
42 (other darwin) Probably OK (not tested)
43 Linux Linux UNIX OS OK
44 Sparc OK
45 HPUX H.P. Unix 10? Not Tested
46 Solaris SUN Solaris 7? OK (now)
47 Irix SGI Irix 5? Not Tested

49 A new list has now been compiled of all the operating systems so that I
51 can individually keep information on their success.
52 THIS IS IN NEED OF AN UPDATE AFTER NEXT RELEASE.

154 Unix
155 Most unix systems have trouble working out the fully qualified domain
156 name as it to be configured somewhere in the system correctly. For
157 example in most linux systems (debian, ?) the fully qualified name
158 should be the first entry next to the ip number in /etc/hosts
