一、下载源程序
git clone https://github.com/semigodking/redsocks.git
二、编译
cd redsocks-master make
会出错：
parser.c: In function 'vp_in_addr': parser.c:306: error: 'AI_ADDRCONFIG' undeclared (first use in this function) parser.c:306: error: (Each undeclared identifier is reported only once parser.c:306: error: for each function it appears in.) make: *** [parser.o] Error 1
三、解决，在parser.c文件的第32行插入如下代码：
#ifndef AI_ADDRCONFIG #define AI_ADDRCONFIG 0x0020 #endif
下载源码： https://github.com/madeye/shadowsocks-libev
直接编译会出错：
/tmp/cciqCfzf.s: Assembler messages:
/tmp/cciqCfzf.s:2903: Error: opcode not supported on this processor: mips1 (mips1) `sync'
修改 \shadowsocks-libev-master\libev 下的 ev.c ：
找到:
#define ECB_MEMORY_FENCE __asm__ __volatile__ ("sync" : : : "memory")
改为:
#define ECB_MEMORY_FENCE __asm__ __volatile__ (".set mips2; sync; .set mips0" ::: "memory")
有两处，都改吧。（参考：http://permalink.gmane.org/gmane.comp.lib.ev/2182）
再编译就可以通过了：
网上的都要用到 find -mtime，这个参数默认的 busybox 是不支持的，当然你可以下 findunti ,我这个脚本无需额外的程序支持：

2015.07.03 更新，更好的支持 Tomato ARM 版本：
#!/bin/sh #USE AT YOUR OWN RISK. #THIS SCRIPT DOES NOT COME WITH ANY WARRANTY WHATSOEVER. # #Backs up selected nvram variables in "nvram export --set" format. # #Correctly handles multi-line entries. # #Thanks to ryzhov_al for basic approach. # #Should work equally well with both MIPS and ARM builds. # #Looks for a list of items to export in $etc/scriptname.ini #OR enter items to grep for below. # #The items list is a list of regular expressions to match against the #nvram variable names. # #Script assumes all entries are at beginning of line(prefixed with ^). # #Leave items list blank to backup up all of nvram. Resulting in essentially #the same output as MIPS "nvram export --set" # #The items list below is only intended as example and is not complete or #comprehensive.

比较完美的解决了多行文本框内容的备份，例如脚本等处。
