From 86ba931697790d4da2515f4457ebfb3f20b43860 Mon Sep 17 00:00:00 2001 From: Epoch Qwert Date: Tue, 30 Dec 2014 07:25:39 -0600 Subject: all those .c changes were mostly fixes of warnings for the change in rebuild.sh being changed to use -Wall. gethostbyname was almost completely rewritten to work better with ipv6 for gopherd.sh gopherd.sh was rewritten to use gethostbyname instead of dig and to cut out any link-local interface indicators from the output of hop0 and to ignore an error if ipA -> hostname -> ipB causes ipA to be not the same as ipB. Don't remember if there's anything else. --- src/bin/dcchelper.c | 2 ++ src/bin/gethostbyname.c | 32 +++++++++++++++++--------------- src/bin/ipconvert.c | 2 ++ src/bin/pad.c | 1 + src/bin/rrd.c | 16 +++++++--------- src/bin/speed.c | 1 + src/libexec/deddos.c | 8 +++----- src/libexec/httpd.c | 2 +- src/libexec/peerip.c | 12 +++--------- 9 files changed, 37 insertions(+), 39 deletions(-) (limited to 'src') diff --git a/src/bin/dcchelper.c b/src/bin/dcchelper.c index bf8f28b..50009aa 100644 --- a/src/bin/dcchelper.c +++ b/src/bin/dcchelper.c @@ -1,4 +1,6 @@ #include +#include +#include int main(int argc,char *argv[]) { char *wanip;
