GNU inetutils - The GNU Networking Utilities



The GNU Networking Utilities are the common networking utilities,

clients and servers of the GNU Operating System.



The individual utilities were originally derived from the 4.4BSDLite2

distribution.  Many features were integrated from NetBSD, OpenBSD,

FreeBSD and GNU/Linux.



The file `paths' contains a list of all paths used by programs in this

distribution, and rules to find values for them.  To change a path

PATH_FOO, you may either tell configure, by using

`--with-path-foo=VALUE' (where VALUE may contain references to make

variables such as `$(bindir)'), or edit the `paths' file.  See further

below for some important cases.



If you wish to build only the clients or only the servers, you may

wish to use the --disable-servers or --disable-clients options when

invoking `configure'.  You can also use --enable- or

--disable- to control whether to build individual programs;

if you explicitly specify whether to build a program, that will

override the values specified by --disable-clients or

--disable-servers.



The GNU whois client reads a whois-servers file to figure out which

whois server to use.  It won't always pick the best server;

whois.internic.net seems to know something about nic.ddn.mil, but the

GNU whois client will use nic.ddn.mil to look up nic.ddn.mil if you

use the configuration file we supply.  Our configuration file probably

also does not have a complete list of whois servers; feel free to send

information about additional whois servers to the bug reporting

address.



Notes on setuid-executables:



 - All of the r* client commands, 'rcp', 'rlogin', 'rsh', used to need

   to be installed as setuid root to work correctly, since they use

   privileged ports for communication.  However, some modern operating

   systems now offer capabilities that avoid the need for setuid

   settings, and this is accounted for in our present code.

   CAP_NET_BIND_SERVICE and PRIV_NET_PRIVADDR are relevant for the

   above three programs.



 - Similarly, 'ping', 'ping6', and 'traceroute', used to depend on

   setuid installation, but also these are now content with

   capabilities like CAP_NET_RAW, PRIV_NET_ICMPACCESS, and

   PRIV_NET_RAWACCESS.



Notes on hard-coded file locations:



 - Some of the buildable executables depend critically on hard-coded

   file locations for correct execution.  The most important, where

   care is needed, are highlighted below.



 - `ftpd' needs access to several configuration files, in order that

   all use cases be covered.  Both of PATH_FTPCHROOT and

   PATH_FTPWELCOME are normally positioned correctly in sysconfdir by

   default, whereas PATH_FTPUSERS usually is desired to state

   `/etc/ftpusers', but not all systems manage this.  Particular care

   should be given to PATH_FTPLOGINMESG, since it defaults to

   `/etc/motd', which cannot be claimed as universally ideal.  A

   sensible counter measure could be



     ./configure --with-path-ftploginmesg='$(sysconfdir)/ftpmotd'



   This would, however, complicate matter for chrooted users, so a

   minor variation on the default could be preferable:



     ./configure --with-path-ftploginmesg=/etc/ftpmotd



   Finally, the fall-back value `/etc/nologin' for PATH_NOLOGIN is in

   effect for every systems lacking , but this sets the most

   plausible location in any case.



 - `rcp' relies on PATH_RSH for proper hand-over.  Use the

   configuration switch `--with-path-rsh=VALUE' for overriding the

   detected value.  It should point to the intended location of `rsh',

   particularly when built with Kerberos support.



 - Similarily, `rsh' needs PATH_RLOGIN to locate `rlogin' for correct

   delegation.  The switch `--with-path-rlogin=VALUE' may come handy

   to ensure that `rsh' as well as `rlogin' offer identical Kerberos

   support.



Some known deficiencies:



 - Non-Shishi Kerberos support does not build.  Patches welcome.



 - Shishi Kerberos support is only implemented for 'rcp', 'rlogin',

   'rlogind', 'rsh', 'rshd', 'telnet', and 'telnetd'.



 - Not all utilities are Kerberized even when built with Kerberos

   libraries, including 'rcp' for non-Shishi Kerberos.



 - InetUtils does not build on HP-UX 11.00, Cygwin, Minix, MinGW,

   MSCV, BeOS, Haiki (and probably other systems as well).  Patches

   welcome.
