* server.c (main): There's some problem with uname () - some systems
|
|
||||||
like Solaris or Digital Unix return a nonnegative value on success,
|
|
||||||
some others like Linux return 0. Since all known systems seem to return
|
|
||||||
a negative value on failure, we simply check whether the return value is
|
|

not negative here.

Larger changes to the daemon:
|
|
||||||
|
|
||||||
- Dropped all the unix domain socket stuff - we don't need it for
|
|
||||||
connections on the local host, here we behave just like any normal
|
|
||||||
application.
|
|
||||||
- Added poptimization: use the --help parameter to get usage info
|
|
||||||
- Made it a real daemon, fork into background and write to syslog.
|
|
||||||
- It's now possible to invoke the daemon from inetd, you'll get
|
|
||||||
GNU_SECURE authentication in this case.
|
|
||||||
- Don't make this executable suid/sgid - if invoked as root it
|
|
||||||
sets uid/gid to SERVER_UID/SERVER_GID as defined in server_config.h
|
|
||||||
- Added missing features, so you can now really use this thing.

|

1998-11-11 Martin Baulig <martin@home-of-linux.org>
|
|
||||||
|
|
||||||
* gnuserv.c (main): Set `server->features' directly rather than
|
|
||||||
calling glibtop_set_parameter_l () since this function no longer
|
|
||||||
allows to modify the features.
|
|
||||||
|
|
||||||
* gnuserv.c, main.c: Use LIBGTOP_ENABLE_DEBUG rather than DEBUG.

|
|

how it ever built without it.

1998-10-20 Martin Baulig <martin@home-of-linux.org>

libtool 1.2. It may work with 1.1 as well, but that's untested.

`write' and `send' to avoid compiler warnings.
|
|

* gnuserv.c (handle_signal): Declared static.

(main): Casting return value of `getuid' to `int' in
|
|
||||||
debugging statement.
|
|
||||||
|
|
||||||
* ChangeLog: New file.
