From 83cf98f113541acca5a9b4d6ad084d401b64706f Mon Sep 17 00:00:00 2001 From: Aravind Srinivasan Date: Wed, 4 Feb 2009 16:05:36 -0800 Subject: Have nmbd check all available interfaces for WINS before failing When nmbd is acting as WINS, it picks the first interface's IP as WINS server's IP. If the first interface's IP is zero, we will just quit (even though we might have other interfaces with valid IPs). This patch makes nmbd look at all interfaces and pick the first interface with a valid IP as the WINS server's IP. --- source3/lib/interface.c | 7 +++++-- source3/nmbd/nmbd_become_dmb.c | 3 ++- source3/nmbd/nmbd_subnetdb.c | 3 ++- 3 files changed, 9 insertions(+), 4 deletions(-) diff --git a/source3/lib/interface.c b/source3/lib/interface.c index 48fa4d32a9..b32ccb9c56 100644 --- a/source3/lib/interface.c +++ b/source3/lib/interface.c @@ -151,7 +151,8 @@ int iface_count_v4_nl(void) } /**************************************************************************** - Return a pointer to the in_addr of the first IPv4 interface. + Return a pointer to the in_addr of the first IPv4 interface that's + not 0.0.0.0. **************************************************************************/ const struct in_addr *first_ipv4_iface(void) @@ -159,7 +160,9 @@ const struct in_addr *first_ipv4_iface(void) struct interface *i; for (i=local_interfaces;i ;i=i->next) { - if (i->ip.ss_family == AF_INET) { + if ((i->ip.ss_family == AF_INET) && + (!is_zero_ip_v4(((struct sockaddr_in *)&i->ip)->sin_addr))) + { break; } } diff --git a/source3/nmbd/nmbd_become_dmb.c b/source3/nmbd/nmbd_become_dmb.c index a0b2ef15f8..827d56cb06 100644 --- a/source3/nmbd/nmbd_become_dmb.c +++ b/source3/nmbd/nmbd_become_dmb.c @@ -128,7 +128,8 @@ in workgroup %s on subnet %s\n", work->dmb_name = nmbname; - /* Pick the first interface IPv4 address as the domain master browser ip. */ + /* Pick the first interface IPv4 address as the domain master + * browser ip. */ nip = first_ipv4_iface(); if (!nip) { DEBUG(0,("become_domain_master_stage2: " diff --git a/source3/nmbd/nmbd_subnetdb.c b/source3/nmbd/nmbd_subnetdb.c index 61af0bb4a4..13bc931863 100644 --- a/source3/nmbd/nmbd_subnetdb.c +++ b/source3/nmbd/nmbd_subnetdb.c @@ -287,7 +287,8 @@ bool create_subnets(void) } if (lp_we_are_a_wins_server()) { - /* Pick the first interface IPv4 address as the WINS server ip. */ + /* Pick the first interface IPv4 address as the WINS server + * ip. */ const struct in_addr *nip = first_ipv4_iface(); if (!nip) { -- cgit
