not just the yp_get_default_domain() domain), we must remove
any old binding files from /var/yp/binding (BINDINGDIR) from
previous runs, or the non-yp_get_default_domain()'s will not
bind properly. add a purge_bindingdir() function that basically
does "rm BINDINGDIR/*.[0-9]" at ypbind startup time.
example case of where this is an issue: bind a second (non-default)
domain. ypbind will create and flock a /var/yp/binding/xxx.2
file for it. stop and restart ypbind. the old /var/yp/binding/xxx.2
file will remain from the previous run. since it is not flock()'d
by the new instance of ypbind, libc functions like yp_master() will
fail without even bothering to talk to ypbind itself. (and ypbind
is totally unaware of the old file...)
to a 2-clause licence (retaining UCB clauses (1) and (2)), per PR
22409 from Joel Baker, approved by Theo de Raadt, and ratified by
myself - the only discrepancy being the handling of the original
clause 3 in src/usr.sbin/yppoll/yppoll.c.
Remove dom_server_port from struct _dom_binding. It's never initialised
and used in only one place, where dom_server_addr.sin_port was probably
intended.
__CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that. It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.
Messages will still be printed to stderr if ypbind is started in debug mode.
- Don't exist if none of the servers listed in
/var/yp/binding/<domainname>.ypservers are reacheable. It's a temporary
failure that can be recovered from.
* cleanup for -Wall
* use __RCSID
the following were inspired by openbsd:
* only allow connections from reserved ports
* implement -insecure, which turns off the above restriction (required
for sunos 3.x and ultrix)
* prevent more than 100 domains from being bound at once, preventing
a denial of service attacks
This is a compromise between the Solaris 2.5 naming of this file
(/var/yp/binding/domain/ypservers and /var/yp/binding/domain/vers)
and traditional NetBSD naming (/var/yp/binding/domain.vers).
Changing to the Solaris naming makes the C library incompatible
with ypbind. While it's easy to change the C library, I don't feel
right about introducing a gratuitous incompatibility.
The current name (/var/yp/domain/ypservers) conflicts with the name
of the YP map listing slave servers for a domain.
Per discussion w/ Chris Demetriou and Luke Mewburn.
of YP servers a client should bind to, mostly verbatim, but slightly
modified for better semantics when nagging servers if a ypset has been
issued. Default to broadcast mode if no .ypservers file is present.
Documentation changes to match, slightly tweaked by Scott Reynolds and
myself.
Closes PR #1759.
- check malloc returns
- null terminate strncpy() strings
- use snprintf instead of sprintf
- pass the right arguments to the right functions
- check usage
- use err(3) and warn(3) instead of printfs.

complaining about not being able to communicate with ypbind). Failure
