#!/bin/bash
#路由器上扫CF的脚本
#运行目录下创建一个cfip.txt定义扫描范围
#每行定义一个网段，例如1.0.0.0/24
#0.0.0.0/0则全网扫描
#扫描结果：查看log.txt
#本次测速结果：查看speedlog.txt
#历史测速结果：查看hspeedlog.txt

#支持输入参数:
#-n <num>表示并发任务数量，默认100。路由运行如果内存不足挂死，可适当调小。手机termux下建议400。
#-k 表示跳过扫描，仅测速。
#-s 表示跳过测速，仅扫描。
#-m <mode>表示扫描模式，0表示https，1表示http
#-c 表示清除断点文件从头扫描，不会清除log.txt、speedlog.txt和hspeedlog.txt文件
#-a <asn>表示以ASN作为扫描范围，例如AS54994则输入-a 54994
#-r 当ftp服务器或worker备份服务器参数已配置时，携带-r参数从服务器上最近一次备份恢复运行环境（断点、log等），当worker和ftp都配置时，从worker恢复。
#-e 表示仅结束脚本时通过ftp或worker备份环境，中途不备份
#-i 表示断点模式测速，保留speedlog.txt并跳过其中已有测速记录的IP

#版本号，请勿修改
ver=20211222-00

######START######
###以下为脚本默认命令行参数，如果不想运行脚本时输入参数，可以直接修改这里
p_default_para="-m 0 -n 880"

######以下为内置参数######
###自定义扫描参数设置###
p_to=2; 
#单个ip扫描超时时间，默认5秒
p_max_load=1000;
#负载控制，高于该负载暂停启新任务，规避老毛子概率性跑死问题，老毛子建议20，没有跑死问题调到1000，相当于没有限制。
###自定义扫描参数设置结束###

###自定义测速设置###
p_st=1; 
#测速次数，可多次测速，取最大值输出
p_delay_mode=0
#时延测试模式，1为ping时延，0为http时延，即测速url的http/https响应时间
p_st_to=10
#每个IP测速时间，默认10秒
p_st_https_url="https://speed.cloudflare.com/__down?measId=6891185455449098&bytes=500000000"
#https测速地址
p_st_http_url="http://speed.cloudflare.com/__down?measId=6891185455449098&bytes=500000000"
#http测速地址
p_speed_filter='| grep HKG' 
#定义从log.txt中筛选测速IP的规则。例如不测洛杉矶的p_speed_filter='| grep -v LAX'
###自定义测速设置结束###

###以下为ftp备份和恢复参数，周期上传到ftp服务器，技能要求高，不懂不要用。
p_bk_ftp_srv="";
#备份服务器地址，例如p_bk_ftp_srv="ftp://user:password@valid.scan.cf:21";，留空表示不备份
p_bk_ftp_dir=/scancf/openwrt/;
#ftp服务器上的备份目录
p_bk_ftp_mode=0;
#ftp模式，1表示被动模式，0主动模式
p_bk_ftp_period=30; 
#备份周期，默认30分钟
p_ftp_rslt_file="cf_speed_result.txt"
#把speedlog.txt重命名后上传到一个命名不带时间的固定目录，方便通过固定URL分享，留空表示不重命名上传。
###ftp备份参数定义区域结束

###以下为worker备份和恢复设置，需要搭建CF worker
p_wk_env_srv=""
#worker备份运行环境的地址，例如"scancfupate.doremi.workers.dev"
p_bk_wk_period=30
#worker备份周期
############

###以下为公共TG推送设置
api_host=""
nickname="神仙"
ipflag="🚀🚀🚀"
msgemoji="🔥"
chat_id="-1001549398293"
