From 2aeb201c9751d4ee82978c623310e14b9e831b94 Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Tue, 17 Apr 2018 12:43:54 +0200 Subject: libbb: new option FEATURE_ETC_SERVICES: if off, /etc/services reads often avoided In practice, "wget http://host.com/" always uses port 80. People explicitly set non-standard ports via options or parameters ("telnet 1.2.3.4 567" or "telnet 1.2.3.4 ftp") instead of modifying /etc/services. function old new delta telnet_main 1466 1464 -2 rdate_main 215 198 -17 fakeidentd_main 269 252 -17 parse_url 459 392 -67 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-103) Total: -103 bytes Signed-off-by: Denys Vlasenko --- libbb/Config.src | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'libbb') diff --git a/libbb/Config.src b/libbb/Config.src index fdf8bbb28..16e16480b 100644 --- a/libbb/Config.src +++ b/libbb/Config.src @@ -76,6 +76,18 @@ config FEATURE_ETC_NETWORKS a rarely used feature which allows you to use names instead of IP/mask pairs in route command. +config FEATURE_ETC_SERVICES + bool "Consult /etc/services even for well-known ports" + default n + help + Look up e.g. "telnet" and "http" in /etc/services file + instead of assuming ports 23 and 80. + This is almost never necessary (everybody uses standard ports), + and it makes sense to avoid reading this file. + If you disable this option, in the cases where port is explicitly + specified as a service name (e.g. "telnet HOST PORTNAME"), + it will still be looked up in /etc/services. + config FEATURE_EDITING bool "Command line editing" default y -- cgit v1.2.3
